Manifold Markets Review 2026: How Does It Work?

If you’ve landed here wondering whether Manifold Markets is worth your time, you’re in the right place.

In this Manifold review, we cover how the platform works, what markets are available, what Mana is and how it works, whether it’s safe and legitimate, and how it honestly stacks up against real-money alternatives like Polymarket and Kalshi.

We also walk you through how to create an account, break down the trading features and tools available, and share a few platform-specific strategies that actually apply here. You’ll also find clear tables throughout to help you compare costs, market types, and platform differences at a glance.

By the time you finish reading, you’ll know exactly what Manifold Markets is good for, where it falls short, and whether it belongs in your prediction market toolkit.

What is Manifold Markets?

Manifold Markets is an online prediction market platform founded in December 2021 by Austin Chen and brothers James and Stephen Grugett. The platform is headquartered in Austin, Texas. 

What makes Manifold Markets genuinely different from most prediction platforms is that it’s based on an open market creation model.

Anyone can create a market on any topic, from serious questions like “Will the Federal Reserve cut rates before July 2026?” to quirky ones like “Will my cat finally learn to use the door handle?” That openness has created one of the broadest and most diverse forecasting communities on the internet.

The platform uses a version of the Uniswap automated market maker, known as “Maniswap,” which means you don’t need a counterparty to take the other side of your trade. The system handles liquidity automatically, which keeps things moving even on less popular markets.

Has it always worked with play money?

Manifold Markets previously experimented with real-money trading through a feature called “Sweepcash,” launched in September 2024. That program was shut down on March 28, 2025. Today, the platform is purely play-money. Mana cannot be converted to cash. The only real-world use of Mana is donating it to charity at a rate of M100 per $1.

This play-money structure keeps Manifold Markets outside the scope of gambling regulations and CFTC oversight, which is a key reason the platform can operate globally without the legal hurdles facing real-money competitors.

Manifold Markets Promo Code & Bonuses

Manifold Markets does not offer a traditional promo code or deposit bonus, because you’re not depositing real money in the first place. Instead, every new user receives 1,000 in free Mana just for signing up. No code required, no strings attached.

Beyond the sign-up grant, you can grow your Mana balance through:

• Prediction streaks: Make at least one prediction per day to earn a daily Mana reward. It starts at Ṁ5 and scales up to M25 per day as your streak extends.
• Quests: The platform periodically offers specific challenges that reward Mana upon completion.
• Market creation: Creating a new market earns you M100.
• Referrals: Refer a friend who signs up, and you earn M1,000.
• Winning trades: The main way to grow your balance is simply predicting well and buying shares at favorable prices.

You can also purchase additional Mana if you want to trade more aggressively. Purchases are available through the platform, though Mana has no cash value and cannot be withdrawn.

Manifold Markets Terms & Conditions

Here are a few things worth knowing:

• Mana cannot be cashed out. The only external use is charitable donation at a fixed M100:$1 rate.
• Purchased Mana is non-refundable. Once you buy Mana, it stays on the platform.
• Referral bonuses are credited after the referred user signs up using your referral link and begins trading.
• The platform can adjust Mana rewards, bonuses, and streak structures at any time. Always check the official Manifold documentation for the most current details.

How to Create an Account on Manifold Markets

Getting started on Manifold Markets is one of the fastest sign-ups in any prediction market platform. Here’s how it works.

Step 1: Visit the Website and Sign Up

Go to manifold.markets and click the “Sign up” button. You can register instantly using a Google account or Apple ID; no separate email and password are required. The whole process takes under a minute.

Step 2: Claim Your 1,000 Starter Mana

Once your account is active, you’ll receive 1,000 in free Mana automatically. No code needed, no verification required. This is your starting bankroll for exploring the platform.

Step 3: Browse or Search Markets

Head to the Browse section to explore active markets. You can filter by category (Politics, Technology, Sports, Culture, Business, and more), sort by activity, or use the search bar to find markets on specific topics you care about.

Step 4: Place Your First Bet

Click on any market and choose your position, typically YES or NO for binary markets. Enter the amount of Mana you want to trade, review the implied probability and expected payout, and confirm the trade. It’s a straightforward process, and the interface shows you clearly how your bet will move the market price.

Step 5: Create Your Own Market (Optional)

If you want to go beyond trading and create your own market, you can do so from the homepage. Creating a market costs M50, which is added to the market’s liquidity pool.

You set the question, resolution criteria, and closing date. Just make sure your resolution criteria are clear and objective. Vague conditions are the most common source of market disputes on the platform.

Is Manifold Markets Legit and Safe?

Yes, Manifold Markets is a legitimate, community-funded prediction market platform with a real team and transparent history.

It was founded in December 2021, has received over $17 million in total funding across multiple rounds, and has hosted the Manifest forecasting conference in Berkeley, California, in 2023, 2024, and 2025, an event that attracted notable figures from the forecasting, economics, and rationalist communities, including Nate Silver.

That said, “safe” means something different here than on a regulated financial exchange. Here’s what you actually need to know:

• No real money at risk. Since everything runs on Mana, you can’t lose real money trading on Manifold Markets. That removes the most significant risk for most users.
• No KYC or identity verification required. You don’t need to provide any personal identification to use the platform. This is by design, given the play-money model.
• Not a regulated financial exchange. Manifold Markets does not operate under CFTC oversight or any gambling license. It explicitly describes itself as an experimental forecasting platform. Users should not expect the protections that come with regulated venues.
• Market resolution risk. Because anyone can create markets with their own resolution criteria, there is a real risk that a market creator resolves a market arbitrarily or in their own favor. The platform has moderation tools and community flagging mechanisms, but resolution quality varies significantly across user-created markets. This is probably the biggest practical concern for regular users.
• Data privacy. The platform collects account and usage data. Review their privacy policy at manifold.markets/privacy before signing up if this matters to you.

Overall, Manifold Markets is a trustworthy platform for learning and forecasting. Just go in with clear expectations: it’s a community-driven forecasting game, not a regulated financial product.

Where Is Manifold Markets Legal?

One of the biggest advantages of Manifold Markets is its global accessibility. Because the platform operates on play money rather than real-money contracts, it doesn’t trigger gambling laws or financial regulations in most jurisdictions.

You won’t find the same country-based access restrictions that affect platforms like Polymarket (limited in the US) or Kalshi (US-only).

To date, no equivalent access bans for Manifold Markets have been documented in any major jurisdiction. The platform is freely accessible from virtually every country, including the United States, the European Union, the United Kingdom, Canada, Australia, and most of Asia and Latin America.

For most users in most countries, Manifold Markets is fully accessible and carries no legal concerns whatsoever. But it’s always worth confirming your local regulations before getting started.

Manifold Markets App & Mobile Experience

Manifold Markets has native apps available on both iOS (requires iOS 15.1 or later) and Android, in addition to its web platform. The mobile apps are free to download and support the full core experience: browsing markets, placing trades, creating markets, and checking your portfolio.

What works well

The web app is arguably the stronger of the two experiences. It’s responsive, information-dense, and easy to navigate, with markets displayed as cards that include probability history graphs. The social feed is genuinely useful, surfacing markets relevant to your stated interests using an algorithmic approach similar to a news feed.

The comment section on each market page is one of the platform’s standout features. It’s where users debate methodology, share news links, and argue about resolution criteria. If you want to understand why a probability just moved, the comments often explain it better than anything else.

Push notifications for market updates are available through the mobile apps, which is helpful for tracking markets you’ve taken a position on.

Where it falls short

The mobile apps have received mixed user reviews, with recurring complaints about slow loading speeds, login issues (particularly around Google SSO with two-factor authentication), and occasional glitches. Some users describe the Android app as feeling like a “web wrapper” rather than a fully native experience. The iOS app requires iOS 15.1 or later, so older devices are excluded.

Based on our testing, the app is functional, but has a lot of room for improvement. The web experience significantly outperforms the native apps, and we’d recommend you stay on the website.

Markets You Can Trade on Manifold Markets

The market selection on Manifold is unlike any other prediction platform. Because anyone can create a market on any topic, the catalog is enormous and constantly expanding. Here’s a breakdown of the main categories.

Politics

Politics is one of the most active categories on Manifold Markets, covering elections at all levels, legislative outcomes, cabinet appointments, international political developments, and policy questions.

The platform gained recognition for its performance during the 2022 US midterms and the 2024 US presidential election, where it posted competitive calibration scores against other platforms. Political markets tend to attract the most trader attention and generally have higher liquidity than niche categories.

Technology & AI

AI is arguably Manifold’s biggest growth area. Markets on artificial intelligence milestones — from model releases and benchmark achievements to AGI timelines and regulatory outcomes — are some of the most actively traded on the platform.

The platform has become a go-to barometer for the broader AI forecasting community, and its markets on AI topics are frequently cited by analysts and researchers.

Sports

Sports prediction markets exist on Manifold Markets, though the depth here is thinner than on real-money platforms like Kalshi (which cleared over $43 billion in sports volume in 2025).

You’ll find markets on major league outcomes, championship winners, and notable sports events, but the liquidity is generally lower and market creation is community-driven rather than curated. For casual sports forecasting, it works fine; for serious sports trading, it’s not the right venue.

Science & Research

This is where Manifold’s permissionless model really shines. Markets on scientific questions (study replications, clinical trial outcomes, physics discoveries, medical breakthroughs) populate a category that most real-money platforms don’t cover at all.

These markets tend to attract knowledgeable forecasters and are particularly popular within the effective altruism and rationalist communities that form a significant part of Manifold’s user base.

Business & Finance

Business-related markets cover company funding events, product launches, executive moves, and macroeconomic indicators like Federal Reserve rate decisions.

Crypto and financial prediction markets also appear here. As with sports, liquidity in financial markets varies considerably. High-profile macro events attract reasonable trading volume; niche company-level markets may have very few traders.

Culture, Entertainment & Personal

One of the most unique aspects of Manifold Markets is the range of personal and cultural markets that wouldn’t exist anywhere else. You’ll find markets on movie box office results, awards shows, video game launches, streamer milestones, and even personal goals set by individual users.

These markets rarely move large amounts of Mana, but they’re a big part of what gives the platform its community-driven personality.

Custom / Meta Markets

Manifold is also home to an active category of meta-markets. These are markets about markets themselves, about the platform, and about the prediction market industry.

One notable example is an active contract asking which prediction market platform will have the highest total trading volume in the current year.

Manifold Markets Trading Features & Tools

Manifold Markets has a well-developed feature set for a community-driven platform. Here’s what’s available:

Market Types

Type	Description
Yes/No (Binary)	Simple binary outcome markets. The most common type.
Multiple Choice	Markets with several possible answers. Can be configured as mutually exclusive (sum to 100%) or independent.
Numeric	Predict a specific number within a defined range.
Polls	Collect opinions without betting (single choice, multi-select, or ranked).
Bounty Questions	Markets with several possible answers can be configured as mutually exclusive (sum to 100%) or independent.

Automated Market Maker (Maniswap)

Manifold uses Maniswap, its own version of the Uniswap AMM derived from the DeFi space. This means you don’t need another user to be on the opposite side of your trade.

The AMM provides liquidity automatically, though the depth of that liquidity scales with the amount of Mana in the market’s liquidity pool. More actively subsidized markets trade more efficiently.

Limit Orders

You can place limit orders to buy or sell shares at a specific probability level rather than at the current market price. This is a useful feature for more experienced traders who want to execute at a particular threshold rather than accepting the current price.

Loan System

For long-term markets (those resolving months or years from now), Manifold provides a loan mechanism. If you have Mana tied up in a long-term position, the platform lends you a portion of that value back so you can continue trading on other markets.

Portfolio Dashboard

Your profile page shows your current positions, profit/loss history, and overall forecasting performance. Manifold tracks calibration data site-wide, and you can also see your own calibration curve to understand how well your confidence levels match real outcomes.

Public API

Manifold offers a free, publicly accessible API that returns live market probabilities, full trade histories, and user-level bet data. This is popular among developers, researchers, and data analysts who want to build tools on top of the platform or analyze forecasting patterns at scale.

Leagues System

Manifold has a competitive leagues feature where traders are grouped by skill level and compete for Mana prizes over seasonal periods. This adds a gamification layer that rewards consistent, accurate forecasting rather than just activity volume.

Social Features

Every market has a comment section where users discuss resolution criteria, share relevant news, and debate probabilities. You can follow individual traders and see their positions. The algorithmic feed surfaces markets relevant to your interests, similar to a social media feed.

Manifold Markets Fees Structure & Trading Costs

Since Manifold Markets runs on play money, you’re never paying real-money fees. However, the platform does charge Mana-denominated fees on trades that affect your Mana balance. Here’s how the fee structure works:

Trading Fee Formula

On Yes/No (binary) markets, the fee is:

Fee = 10% x amount traded x (1 – max price per share bought)

For example, if you buy M50 of YES shares and the price moves from 50% to 70%, your fee is approximately: 10% x M50 x (1 – 0.70) = M1.50

If you buy M50 of NO shares and the price moves from 80% to 40%, your fee is approximately: 10% x M50 x 0.40 = M2.00

Market Creation Fee

Creating a new market costs M50, which is deposited into the market’s liquidity pool rather than collected as revenue. This means your creation fee directly contributes to how tradeable your market will be.

Mana Purchase

If you choose to buy more Mana with real money, you do so through the platform’s purchase flow. The effective exchange rate is approximately $1 per M100, though Manifold may adjust pricing over time. Purchased Mana carries no cash value and cannot be refunded.

Charity Donations

Mana can be donated to a selection of charities at a rate of M100 per $1. This is the only way to convert Mana into real-world value.

Cost Type	Amount
Sign-up	Free
Trading fee (binary markets)	~10% of trade x position factor
Market creation	M50 (added to liquidity pool)
Prediction streak	+M5 to M25 per day
Mana purchase (approx.)	~$1 per M100
Withdrawals	N/A (no cash withdrawals)

Manifold Markets Trading Limits & Liquidity

Trading Limits

Because Manifold Markets uses play money, there are no hard trading limits in the traditional sense. You can bet as much Mana as you have available. The practical limit is the depth of the liquidity pool in any given market.

Since anyone can create a market and liquidity pools start from just M50 (the creation fee), some markets are thinly traded and move significantly with even a small bet.

Others, particularly high-profile political or AI markets that have attracted subsidies from multiple users, can handle larger positions without shifting probabilities drastically.

Liquidity

Liquidity on Manifold Markets is community-driven, which means it varies considerably by market. Here’s a realistic breakdown:

Market Type	Typical Liquidity	Notes
Major political events	Moderate to good	Presidential elections, FOMC decisions, etc. attract the most activity
AI milestones	Moderate	Growing category; active user base from tech/EA communities
Sports events	Low to moderate	Functional but much thinner than real-money sports platforms
Niche / personal markets	Very low	Often one or two traders; prices can be very inefficient
Meta markets (platform forecasts)	Moderate	“Who will lead volume in 2026?” type markets attract real interest

The loan system partially mitigates liquidity constraints by allowing users to keep capital active even when it’s tied up in long-duration positions.

Manifold Markets Trading Strategies & Tips

Manifold Markets rewards skill over time, even though no real money is involved. Here are three practical tips that take advantage of how the platform actually works.

Tip 1: Find Markets Where You Have an Information Edge

The best opportunities on Manifold come from identifying markets priced inaccurately because the general user base lacks the specific knowledge you have. This could be anything from deep expertise in AI research to close following of a niche sports league or an industry sector.

Because markets here don’t have the institutional traders and hedge funds that keep real-money markets sharply priced, inefficiencies are more common. Look for markets sitting at 50% on binary questions where the answer seems obvious to anyone paying close attention (and bet accordingly).

Tip 2: React to News Faster Than the Market

Manifold Markets is a dynamic platform, and prices update continuously as events unfold. If you’re closely following breaking news in any category, there is real Mana to be made by being among the first to trade on new information before the market adjusts.

This is particularly valuable in fast-moving categories like politics, crypto, and AI developments, where a single announcement can dramatically shift the fair probability. Set up notifications for markets you’re watching so you’re ready to move quickly.

Tip 3: Use the Loan System

One of the most useful features specific to Manifold is the loan system. If you take a position on a market that won’t resolve for months or years, a portion of that position value is lent back to you so you can keep trading on shorter-term markets.

This prevents the common frustration of running out of Mana because your balance is locked up in long-duration positions. Use it deliberately.

Take well-considered long-term positions on markets you’re confident about, let the loan system free up capital, and stay active on shorter-term opportunities in parallel. Just keep in mind that loans carry a daily interest charge.

Manifold Markets vs Other Prediction Markets

Manifold Markets vs Polymarket

Polymarket is the global leader in real-money prediction markets, processing over $33.4 billion in trading volume in 2025 alone. Manifold and Polymarket occupy completely different tiers of the market.

Feature	Manifold Markets	Polymarket
Currency	Mana (play money)	USDC (real money)
Trading volume	Very low (play money)	$33.4B+ in 2025
KYC required	No	Yes (for US users post-QCEX)
Market creation	Open to all users	Curated/limited
Fees	~10% of trade (Mana)	Near zero
Geographic access	Global	Global (US via QCEX)
Blockchain	No	Polygon
Best for	Learning, research, niche topics	High-stakes real-money trading

In short, Manifold Markets is where you learn and experiment. Polymarket is where you trade with conviction and real dollars.

The two serve different needs and aren’t really in direct competition for active real-money traders. Interestingly, Manifold’s meta-markets on Polymarket are widely cited as real-time industry indicators, while Polymarket’s odds on Manifold are often referenced in market analysis.

Manifold Markets vs Kalshi

Kalshi is a CFTC-regulated US exchange offering real-money event contracts, backed by institutional investors including Sequoia Capital. It processed over $43.1 billion in trading volume in 2025, largely driven by sports markets.

Feature	Manifold Markets	Kalshi
Currency	Mana (play money)	USD (real money)
Regulation	None (play money model)	CFTC-regulated DCM
KYC required	No	Yes
Fees	~10% of trade (Mana)	0.5% to 1% per contract
Position limits	None (Mana)	Typically up to $25,000 per event
Market categories	Unlimited (user-created)	Curated: sports, politics, finance
Idle cash yield	N/A	~4% APY on idle balances
US availability	Yes	Yes

The key difference is regulatory standing. Kalshi is one of the most institutionally credible prediction market platforms in the world.

Manifold Markets is entirely unregulated, which is only safe because no real money is involved. If you want to trade real money in the US in a fully licensed environment, Kalshi is the more relevant comparison point, but it’s a different product from Manifold in almost every meaningful way.

Manifold Markets Deposits & Withdrawals

Because Manifold Markets is a play-money platform, the traditional concept of deposits and withdrawals doesn’t apply in the way it does on real-money exchanges.

Here’s what you need to consider in this platform in terms of balance management:

• Starting Balance: Every new user receives M1,000 for free upon creating an account. No payment required.
• Purchasing Mana: If you want to buy additional Mana, you can do so through the platform. Payment methods for Mana purchases are processed through Manifold’s standard checkout, which typically accepts major credit and debit cards. The indicative exchange rate is approximately $1 per M100, though this can change. Always check the current rate on the platform before purchasing.
• Withdrawals: There are no cash withdrawals. Mana cannot be converted to real money under any circumstances since the Sweepcash program ended.
• Charity Donations: The only way to convert Mana into real-world value is through charitable donation at a fixed M100:$1 rate. Manifold supports donations to a curated list of charities directly from your account.

Manifold’s Customer Support & Help Center

Manifold Markets provides customer support primarily through community and documentation channels rather than dedicated support staff.

Available support options:

• Documentation / FAQ: Manifold maintains a comprehensive FAQ and help center at docs.manifold.markets, covering everything from how Mana works to market creation best practices and API documentation.
• In-platform moderation: For market-specific issues, users can tag @mods in any market’s comment section to flag problems or request clarification. The moderation team monitors these and resolves markets that have been abandoned or are disputed.
• Discord: Manifold has an active Discord server that serves as the main community hub. It’s a good place to ask questions, report bugs, and connect with other traders.
• Social channels: The platform is active on social media and the team has historically been responsive there for visibility issues or product feedback.

What’s missing:

There is no live chat, dedicated email support ticketing system, or phone support. For a platform where real money is involved, this would be a concern — but since Mana has no cash value, the risk of something going seriously wrong with your “funds” is low. The bigger practical concern is market resolution disputes, and those are handled through moderation rather than formal support.

The support setup is appropriate for a community-driven, play-money platform, but users who are used to the more structured support environments of regulated exchanges (like Kalshi) may find it less formal than expected.

PredictGeek’s Final Words on Manifold Markets

Manifold Markets is one of the most genuinely useful platforms in the prediction market space, just not for the reasons most trading platforms are useful.

There’s no real money here, which means you’re not building a portfolio you can cash out. But what you are building is something arguably more valuable for a newcomer: forecasting skill, calibration awareness, and a practical understanding of how prediction markets work before you ever put real dollars on the line.

The platform is completely free to try, requires no ID, and is accessible globally. For someone new to prediction markets, that’s a nearly frictionless entry point.

What stands out to me most about Manifold is the wide market coverage. No other platform covers the combination of AI milestones, niche scientific questions, political minutiae, and community-created personal markets that you’ll find here. It’s chaotic in a good way. If you care about a topic, there’s a reasonable chance a market exists on it, and if there isn’t, you can create one in under a minute.

The trade-offs are real, though. Play-money incentives are weaker than real-money ones, and that does affect forecast quality and trader engagement. Resolution quality varies considerably across user-created markets, and the mobile apps are due for a serious update. Liquidity on anything outside the top-tier political and AI markets is thin.

Our conclusion is that if you want to learn prediction markets risk-free, build your forecasting instincts, or tap into one of the broadest and most active forecasting communities on the internet, Manifold Markets is well worth your time.
