Sports prediction markets let you trade on game outcomes and player stats, like a stock market for your favorite sports.
After spending a good time testing the markets, we’ll walk you through the best sports prediction market platforms you can use right now, how these markets actually stack up against regular sports betting, you’ll learn all the important terminology you need, and how to get started in the simplest way possible.
We’ll help you figure out whether Kalshi, or one of the other options, makes the most sense for you, and give you updates on what’s legal and what’s not in 2026. Let’s win this game together!
What Is a Sports Prediction Market?
A sports prediction market is a platform where you can trade contracts based on the outcomes of sporting events.
Think of it like a stock market, but instead of trading shares in companies, you’re trading on whether Seattle will win the Big Game or if LeBron will score over 25 points. Each contract represents a simple yes or no answer to a question about a sports event.
Now, you might be thinking, “I can bet on that on a sportsbook as well.” But here’s the key difference from traditional sports betting: prices aren’t set by a sportsbook or sharp bookmaker. They’re set by what other traders like you are willing to pay, based on how likely they think the outcome is.
If a contract costs 65 cents, the market is saying there’s roughly a 65% chance that the outcome will happen.
The platform acts as an exchange, matching buyers with sellers, much like how stock exchanges work. You’re not betting against “the house.” You’re trading with other people who have different opinions about what’ll happen.
How Sports Prediction Markets Work
Event contracts are the building blocks of prediction markets. Each contract pays out exactly $1.00 if the outcome you choose happens, and $0.00 if it doesn’t.
Let’s use an example:
You believe the Patriots will win their next game. You buy a “Patriots win” contract for 58 cents. If the Patriots win, your contract becomes worth $1.00, and you profit 42 cents (minus a small fee). If they lose, your contract expires worthless, and you lose the 58 cents you paid.
The price of 58 cents reflects what the market collectively believes is the probability of the Patriots winning. As new information comes in, like injury reports, weather updates, or betting activity, prices change in real time.
You can also sell your contracts before the game ends. Maybe you bought at 58 cents, but now the price has risen to 72 cents because the Patriots are favored even more heavily. You can sell for an immediate profit without waiting for the final outcome.
The beauty of these contracts is their transparency. You can always see exactly what you’re risking and what you stand to gain.
Sports Prediction Markets vs Sports Betting
While sports prediction markets and traditional sports betting might seem identical on the surface, they work fundamentally differently. Understanding these differences helps you know what to expect from each:
| Feature | Prediction Markets | Traditional Sportsbooks |
| Price Setting | Determined by supply and demand from traders | Set by oddsmakers with built-in profit margin (vig) |
| Who You’re Against | Trading with other users (peer-to-peer) | Betting against the house |
| Flexibility | Buy and sell anytime before event ends | Locked in once placed (unless cash-out offered) |
| Cost Structure | Transparent fees (1-2% per trade) | Hidden vig built into odds (4-5% per side) |
| Regulation | Federal CFTC oversight | State-by-state gambling regulation |
| Market Selection | Limited but growing (winners, spreads, totals, major props) | Extensive (moneylines, spreads, totals, props, parlays, live betting) |
The practical difference for you as a user often comes down to odds value, market selection, and legal access. Some traders use both, comparing prices to find the best value for specific outcomes. If you want to expand on this, read our prediction markets vs sports betting analysis article.
Best Sports Prediction Market Apps in [month_year]
The sports prediction market space has exploded in 2025 and early 2026, with several major platforms now competing for users. Here’s what you need to know about each leading option.
Kalshi sports prediction markets
Kalshi pioneered CFTC-regulated sports prediction markets and still dominates liquidity. During our testing across NFL and NBA markets, we consistently found bid-ask spreads of just 1-2 cents on popular games, compared to 5-10 cents on competing platforms.
Their Request for Quote (RFQ) system for custom parlays is the most advanced we’ve used. You can combine up to 10 different outcomes and get instant pricing. We built a five-leg parlay combining three NFL game winners with two player props and got filled within seconds.
The platform covers all major sports: NFL, NBA, MLB, NHL, college football, and college basketball. We’ve traded a little bit of everything, and the depth of available markets beats every competitor.
Fees cap at $1.74 per $100 traded, and they pay 4% interest on idle cash (we’ve earned a few extra dollars just from funds sitting between weekend trades).
Robinhood sports prediction markets
Robinhood’s prediction markets run on Kalshi’s exchange, but with a cleaner interface if you’re already comfortable with their investment app.
We tested their NFL and NBA markets side-by-side with Kalshi and found identical pricing, which makes sense since they share the same order book. The integration is seamless. Your sports contracts appear right next to stocks in your portfolio view.
Their live player prop feature, launched in December 2025, lets you trade on individual performances as games unfold. We bought Jayson Tatum “over 25 points” contracts during a Celtics game and watched the price swing from 52 cents to 78 cents as he heated up in the third quarter.
Custom parlays arrived recently, though the selection is more limited than Kalshi’s standalone platform. Robinhood charges about $0.01 per dollar traded on top of standard fees. They’ve pulled back from some states, so check availability in your state before signing up.
Underdog sports prediction markets
Underdog blends prediction markets with daily fantasy sports, creating a hybrid experience we haven’t seen elsewhere. You can build a DFS lineup and trade prediction market contracts in the same session.
We tested their “Combo” feature, pairing a three-player fantasy entry with an over/under contract on total points. It’s a unique product if you’re already into DFS.
The sports selection is solid: NFL, NBA, NHL, MLB, college football, soccer, and tennis. Powered by Crypto.com’s exchange, we found liquidity was decent on NFL Sundays but thinner on weeknight MLB games, for example.
During our Super Bowl testing week, spreads on the championship game stayed under 3 cents, but prop markets had wider gaps of 5-8 cents. Deposits only work via debit cards, Apple Pay, or Trustly; there are no ACH or wire transfers, which slowed our funding process.
Crypto.com sports prediction markets
Crypto.com powers the backend for Underdog and Fanatics but also runs its own direct platform Crypto.com Predictions.
We tested all three to compare, and honestly, unless you’re already deep into their crypto ecosystem, you’re better off using one of their partner platforms with more polished interfaces. The sports markets are identical since they all use the same exchange.
One major concern from our testing: Crypto.com implements a 3-second delay for retail traders. We noticed this immediately when trying to react to an injury announcement. Our order sat for three seconds while the price moved against us.
Institutional market makers don’t face this delay, creating an uneven playing field. Markets cover major U.S. sports with game winners, spreads, totals, and player props. You can fund via ACH, wire, or mobile wallets, but the platform isn’t available in New York.
FanDuel sports prediction markets
FanDuel entered prediction markets cautiously with FanDuel Predicts, and it shows in their curated sports selection. Through CME Group’s exchange, they offer game winners, spreads, totals, and basic player props on NFL, NBA, MLB, NHL, and college football.
We tested during the NFL playoffs and found respectable liquidity on marquee games, but struggled to fill orders on midweek sporting events.
They share CME’s order book with DraftKings Predictions, so pricing is identical between the two platforms. Pre-built parlays arrived before Super Bowl 2026, and we tested a three-leg combo (game winner + over/under + player touchdown) that filled instantly at fair pricing.
The interface looks exactly like their sportsbook, which helps if you’re already a FanDuel user, but serious traders will find the market selection limited. FanDuel requires full KYC, including Social Security number and government ID, which took about 10 minutes to complete during our sign-up.
DraftKings sports prediction markets
DraftKings Predictions launched big across the US and immediately grabbed market share. We tested across California and Texas, two major markets where traditional sports betting isn’t available, and found strong liquidity on football and basketball.
They added extensive player props before Super Bowl 2026. We traded contracts on rushing yards, receiving touchdowns, and even halftime show outcomes.
Like FanDuel, they use CME Group’s exchange currently but are transitioning to their own after acquiring Railbird for $250 million. During our testing month, they processed over $120 million in volume, and you could feel the difference in tighter spreads compared to smaller platforms.
Pre-built parlays work well for casual trading. We tested combinations of game winner, spread, and player props that filled in under two seconds.
The app interface mirrors their sportsbook design, making navigation intuitive if you’ve used DraftKings before. Sports contracts are limited to fewer states, while other categories are more open across the country.
Fanatics sports prediction markets
Fanatics Markets launched using Crypto.com’s infrastructure. We tested it and found the experience nearly identical to Underdog since both run on the same exchange.
Game winners, spreads, totals, and select player props are available, with liquidity concentrated on major matchups.
The platform looks more like a traditional sportsbook than Kalshi’s exchange-style interface. If you’re transitioning from betting apps, the familiar layout helps, but serious traders might prefer more detailed market data.
Fanatics requires users to be 21+, stricter than the typical 18+ minimum for CFTC products. A big win is for those already buying team gear or tickets through Fanatics; the integration across their ecosystem is the smoothest we’ve tested.
Mobile Sports Prediction Market Apps vs Desktop
Most major prediction market platforms prioritize mobile apps. Mobile apps give you instant access wherever you are.
You can respond to breaking news, injury reports, or sudden price movements without being tied to a computer. Push notifications keep you updated on market movements and event results.
The trade-off is screen size. Analyzing multiple markets, comparing odds across events, or conducting research is more difficult on a phone than on a larger screen, especially if you are a geek going serious about event trading, just like us.
Here is a table comparing both options, so you can see what the pros and cons are for each.
| Feature | Mobile Apps | Desktop/Web Platforms |
| Best For | Quick trades, responding to breaking news, on-the-go access | In-depth research, comparing multiple markets, portfolio management |
| Advantages | Instant access anywhere, push notifications for market movements, react to injury reports immediately | Larger screen for analysis, side-by-side market comparison, detailed charts and data, easier multi-market trading |
| Limitations | Small screen makes research difficult, harder to compare odds across events | Requires computer access, less convenient for quick reactions |
| Ideal User | Casual traders (few games per week), mobile-first sports fans who check scores on phone | Serious traders who research deeply, users who work with spreadsheets and data |
| Sync Capability | Full account sync – trades made on mobile appear on desktop | Full account sync – positions, balance, and history accessible across all devices |
| Recommended Approach | Use mobile for execution and quick position management | Use desktop for research and planning, then switch to mobile for trades |
How to Choose the Best Sports Prediction Market Site
With several platforms competing for your business, deciding where to trade depends on your specific situation and priorities.
Check Availability and Liquidity
Start by confirming which platforms operate in your state. Sports prediction markets are more limited than other categories, and state coverage shifts constantly.
Liquidity determines how easily you can buy and sell at fair prices. Kalshi dominates liquidity due to their first-mover advantage and Robinhood partnership.
Make sure to check the bid-ask spread before trading. If buying costs 58 cents but selling costs 42 cents, that 16-cent gap eats into your profits.
Compare Fees and Markets
Kalshi caps fees at $1.74 per $100 traded. Robinhood adds $0.01 per dollar on top of Kalshi’s rates. Crypto.com, Underdog, and Fanatics follow their exchange fee schedules. For occasional traders, fee differences are minimal, but they matter if you trade frequently.
Kalshi offers the broadest event selection across sports, politics, and economics. Sportsbook operators like FanDuel and DraftKings focus primarily on sports but with more limited options.
Check whether your preferred platforms offer the contract types you want. Not all support player props or custom parlays yet.
Consider User Experience and Integration
Test a few platforms to see which interface works for you. Kalshi feels like a financial exchange, while Fanatics and DraftKings resemble traditional sportsbooks.
If you already use Robinhood for investing or Underdog for DFS, their prediction markets integrate seamlessly with your existing account.
Check payment methods and withdrawal speeds. Some platforms require bank transfers, others accept debit cards or Apple Pay. All major platforms have CFTC regulation, but they’re fighting different legal battles with varying levels of aggression.
Try a couple of platforms with small deposits to find what works best for you. Keep in mind you can always consolidate later.
Types of Sports Prediction Market Contracts
Through our testing across multiple platforms, we’ve found that most offer six core contract types, each with different risk profiles and trading dynamics.
Game Winners (Moneyline)
These are the simplest markets. You’re trading yes/no contracts on which team wins outright. We’ve found these have the tightest spreads on major matchups since they attract the most volume. A contract priced at 72 cents means the market thinks that team has about a 72% chance to win. During our trades on NFL Sunday games, we consistently saw bid-ask spreads of just 1-2 cents on popular matchups.
Point Spreads
Point spreads add a handicap to level the playing field between mismatched teams. Instead of just “Will the Chiefs win?”, you’re trading on “Will the Chiefs win by more than 7 points?” These contracts let you find value when a heavy favorite faces a weak opponent. In our experience, spread markets often react slower to injury news than game winner markets, creating brief opportunities if you’re paying attention.
Point Totals (over/under)
Totals focus on the combined final score rather than who wins. You’ll trade contracts on whether both teams score more or less than a set number. We’ve noticed these markets are particularly sensitive to weather reports and pace-of-play stats. Indoor arena games like NBA tend to have more stable pricing than outdoor sports where conditions matter.
Props or Propositions
Player Props let you trade on individual performances: will a quarterback throw for over 250 yards, will a player score a touchdown, will someone grab 10+ rebounds. These have become our go-to for finding mispriced contracts because they require deeper research that casual traders often skip. The liquidity can be thinner than game-level markets, but we’ve found the best opportunities here when we’ve done our homework on matchups and usage rates.
Futures
These are long-term contracts on season outcomes like championship winners, MVP awards, or playoff qualifiers. These tie up your money for weeks or months, but the advantage is watching your position gain value as a team goes on a winning streak. We’ve held futures contracts that doubled in price before the season even hit the halfway point, letting us lock in profits early rather than sweating out the final outcome.
Parlays and Combos
These arrived later in prediction markets, but we are seeing them become common.Parlays and combos bundle multiple outcomes into one contract where everything needs to hit for you to win. A three-leg parlay combining “Patriots win + over 45 points + Mahomes throws 2 TDs” might cost 15 cents but pays a dollar if all three happen.
The math works against you exponentially with each leg you add. After tracking dozens of our own parlay trades, we can confirm what the data shows: these are entertaining but rarely profitable long-term. Stick to two or three legs max if you trade these at all.
Tips for Trading in Sports Prediction Markets
Understanding mechanics is one thing. Trading profitably is another. The key to sustainable success with sports prediction markets is treating this like trading or investing, not gambling. Develop a process, stick to it, track results, and continuously learn from outcomes.
Here are a few recommendations from the PredictGeek.com team:
Start Small and Understand Probability
Your first trades should be about education, not profit. Start with small positions on events you understand well. This lets you learn how pricing moves, how to enter and exit positions, and how fees impact your returns. Resist the temptation to make large trades until you’ve completed at least 20-30 smaller ones and understand what you’re doing.
Contract prices represent market consensus on probability. A contract at 67 cents implies a 67% chance of that outcome occurring.
Ask yourself: Does my analysis suggest the true probability is higher or lower than what the market thinks?
Only trade when you believe the market has mispriced the probability. If you think something has a 75% chance of happening but contracts are priced at 67 cents, that’s a potential opportunity.
Manage Risk and Liquidity
Prediction markets aggregate crowd wisdom, but they can be slow to react to breaking news. If you’re watching injury reports, weather updates, or lineup announcements closely, you might spot opportunities before prices adjust. This edge is temporary and small, but it can matter if you act quickly.
Before entering a position, check the liquidity. Can you easily exit if needed? Look at the spread between buying and selling prices. Wide spreads mean you’ll lose money just from entering and immediately exiting. Stick to popular markets with tight spreads, especially when starting out. Exotic props and small-market games might have attractive prices but poor liquidity.
Instead of buying at the current asking price, place limit orders at the price you’re willing to pay. This lets you wait for the market to come to you rather than crossing the spread immediately. For example, if buying costs 58 cents but selling costs 56 cents, place a limit buy order at 57 cents. You might get filled at a better price than market orders would provide.
Avoid Common Pitfalls
Multi-leg parlays offer huge potential payouts from small stakes, which makes them attractive. But they’re overwhelmingly losing propositions, just like at traditional sportsbooks. Every leg you add exponentially increases your chances of losing everything. If you do trade parlays, keep them to 2-3 legs maximum and understand you’re essentially buying lottery tickets.
Keep a simple spreadsheet of your trades: what you bought, what you sold, the outcome, and your profit/loss. This accountability helps you identify what’s working and what isn’t. Many traders think they’re profitable but haven’t actually tracked their all-time results. Don’t be one of them.
Prices fluctuate based on when you trade. Lines often move significantly in the hours before an event as more information becomes available and volume increases. Early in the week, you might find softer prices. Right before an event, liquidity is highest but prices are most efficient.
After a losing trade, the temptation is to make a bigger trade to win it back quickly. This almost always leads to worse decisions and larger losses. Treat each trade independently. Your previous results shouldn’t influence position sizing on the next one. Frequent trading racks up fees quickly. Before entering a trade, calculate what profit you need to overcome fees and the spread. Sometimes the best trade is no trade at all.
Practice Discipline
Don’t put a huge percentage of your bankroll on a single outcome. Even “sure things” fail. Spreading your capital across multiple independent events reduces the risk that one bad outcome wipes you out. A common rule: never risk more than 2-5% of your total bankroll on any single position.
Many successful prediction market traders share insights on social media and forums. Follow experienced traders, read their analysis, and understand their reasoning. That said, don’t blindly copy others. Use their insights to inform your own independent analysis.
You don’t need to have an opinion on every game. Sometimes the market pricing is accurate, and there’s no edge to be found. Patience to wait for genuine opportunities beats forcing trades just to have action.
Being able to exit positions early is powerful. If you made a trade based on certain assumptions and those assumptions change, don’t stubbornly hold until the event concludes. Cut losses when you’re wrong. Lock in profits when you’ve captured most of the available value.
Legal & Safety Considerations
Sports prediction markets operate in a complex and evolving regulatory environment. Understanding the legal landscape and protecting yourself should be top priorities.
The Regulatory Debate
The central legal question is whether sports prediction markets fall under exclusive federal regulation by the CFTC, or whether states can also regulate them as gambling.
Platforms like Kalshi argue that the Commodity Exchange Act gives the CFTC sole authority over their event contracts, classifying these products as derivatives rather than gambling. Many states disagree, arguing that sports prediction markets are functionally identical to sports betting and should require state gambling licenses.
As of early 2026, Kalshi faces cease-and-desist orders from ten states, including Nevada, New Jersey, Maryland, and Massachusetts. Federal courts have issued mixed rulings. Some sided with Kalshi, finding that federal law preempts state gambling regulations. Others ruled against Kalshi and allowed state enforcement action. The Third Circuit Court of Appeals and potentially the Supreme Court will likely provide more definitive answers in the coming years.
This uncertainty creates risk for users. Platforms operating in your state today might face restrictions tomorrow. Major platforms have stated they’ll honor all contracts and allow withdrawals even if forced to stop accepting new trades in certain states, but regulatory changes could complicate things.
Age, Taxes, and Consumer Protection
Most CFTC-regulated prediction markets set the minimum age at 18, though some platforms like Fanatics Markets voluntarily increased their age limit to 21+. Profits from prediction markets are taxable, similar to investment gains or gambling winnings.
Platforms issue 1099 forms reporting your trading activity to the IRS. Keep your own records of all transactions and consult a tax professional for guidance specific to your situation.
CFTC oversight provides consumer protections, including requirements for platforms to maintain customer funds separately from operating capital, position limits to prevent manipulation, and transparent settlement procedures. However, these differ from state gambling regulations, which often include specific responsible gaming requirements and self-exclusion programs.
Avoid keeping large balances in your prediction market accounts beyond what you plan to trade actively. Withdraw profits regularly.
Responsible Trading and Platform Verification
Prediction markets use the language of trading and investing, but the risks are similar to gambling. You can lose money quickly, especially if you’re trading emotionally or beyond your means.
Set deposit limits, take breaks, and never trade with money you can’t afford to lose. If you find yourself chasing losses or trading compulsively, seek help from the National Council on Problem Gambling at 1-800-GAMBLER.
Before depositing money, verify that the platform is properly registered with the CFTC through the National Futures Association’s registration database. Avoid platforms that aren’t transparent about their regulatory status or that make exaggerated claims about guaranteed returns.
The regulatory landscape changes frequently, so follow industry news, platform announcements, and legal developments. Legal uncertainty shouldn’t necessarily stop you from participating, but it should inform how much you commit and how closely you monitor developments.
PredictGeek’s Opinion: Are Sports Prediction Markets Worth It?
Sports prediction markets offer real advantages if you know what you’re getting into.
The biggest appeal right now is access. If you live in California, Texas, or another state where online sports betting isn’t legal, prediction markets let you trade on games without crossing state lines. Beyond availability, you get flexibility that traditional bets don’t provide. Exit positions early when circumstances change, lock in profits before events finish, and trade at transparent prices without hidden sportsbook vig eating into your returns.
That said, prediction markets aren’t perfect replacements for established sportsbooks. You’ll find fewer betting options, thinner liquidity on smaller markets, and an uncertain regulatory landscape still working itself out through the courts. The industry is evolving rapidly, with platforms launching, merging, and adjusting to legal challenges across different states.
If you decide to participate, treat it like any investing activity: start small, track your performance honestly, and stay updated on both market dynamics and regulatory developments.
Whether prediction markets become the dominant model or carve out a specific niche depends largely on pending court decisions. For now, they represent a legitimate alternative that’s particularly valuable in states where traditional options don’t exist.
