Prediction market volume hit $63B in 2025 and sports bettors are driving it. Here’s what you actually gain, what you give up, and whether it’s worth your time.

Sports bettors are leaving money on the table, and prediction markets are where they’re finding it. The numbers tell the story: prediction market trading volume surged past $63 billion in 2025, a fourfold increase from the prior year.1Gambling Insider, “Prediction Markets Statistics 2026,” gamblinginsider.com, February 2026 FanDuel, DraftKings, and Robinhood have all launched prediction market products. The New York Stock Exchange’s parent company invested $2 billion in Polymarket.2TRM Labs, “How Prediction Markets Scaled to USD 21B,” trmlabs.com, March 2026 This is not a fringe experiment anymore.
If you’ve spent years reading odds, managing a bankroll, and grinding out edges on sportsbooks, prediction markets offer something worth your attention: lower costs, broader markets, and the ability to trade out of positions before events resolve. But the picture isn’t all upside. Thinner liquidity, unfamiliar interfaces, and crypto friction on some platforms are real tradeoffs.
This article lays out both sides honestly. You’ll get the case for making the move, the genuine downsides, and a decision framework based on your specific background and goals. No sales pitch. Just the information you need to decide whether prediction markets deserve a spot alongside your sportsbook.
The growth is not subtle. Global prediction market trading volume hit $63.5 billion in 2025, up from roughly $15.8 billion in 2024.3Gambling Insider, “Prediction Markets Statistics 2026,” gamblinginsider.com, February 2026 Monthly active users climbed from around 4,000 in early 2024 to over 600,000 by late 2025. Those are not projections. Those are recorded transactions on regulated and tracked platforms.
The institutional signal is even louder. In October 2025, the Intercontinental Exchange (parent of the New York Stock Exchange) invested up to $2 billion in Polymarket at an $8 billion valuation.4TRM Labs, “How Prediction Markets Scaled to USD 21B,” trmlabs.com, March 2026 DraftKings acquired prediction market startup Railbird Technologies and launched its own product in December 2025.5Boston Globe, “To DraftKings, the prediction markets are both a threat and an opportunity,” bostonglobe.com, April 2026
FanDuel partnered with CME Group to create FanDuel Predicts, routing trades through one of the world’s largest derivatives exchanges.6International Banker, “Accounting for the Explosive Growth in Prediction Markets,” internationalbanker.com, January 2026 Robinhood reported that prediction markets became its fastest-growing product line by revenue, with annualized prediction market revenue reaching $435 million by Q4 2025.7FalconX Research, “From Opinions to Odds,” falconx.io, February 2026
The sports betting industry has taken notice. More than 80% of prediction market volume now comes from sports event contracts.8Yahoo Finance/Covers, “Prediction Market Volume Quadrupled in Past 2 Years,” yahoo.com, March 2026 For states with legalized sports betting, this has triggered regulatory battles, with over a dozen states filing lawsuits against prediction market operators.9NPR, “As hoops betting spikes, it’s states vs. prediction markets,” npr.org, April 2026 The legal landscape is evolving fast, but the direction of capital is unmistakable: money is flowing from traditional sportsbooks into prediction markets, and the biggest names in gambling are following it.
| By the Numbers Prediction market trading volume grew from less than $100 million per month in early 2024 to over $13 billion per month by late 2025. Industry analysts project the sector could process over $1 trillion annually by 2030. |
Those numbers explain the why. Here’s what the shift actually looks like for someone used to sportsbooks.
The structural differences between prediction markets and sports betting start with how you pay for access to the market.
On a traditional sportsbook, the vig is baked into every line. A standard NFL moneyline might show -110/-110, meaning you pay roughly 4.5% to the house on every bet. On a prediction market exchange like Kalshi, you trade against other users, not against the house. Kalshi’s fees are capped at $0.02 per contract.10Kalshi, “Fee Schedule,” kalshi.com, February 2026 The cost is the spread between buyers and sellers, which on liquid markets runs 1 to 5 cents. On high-volume political and economic contracts, that spread can drop to 1 to 2 cents, a 1 to 2% effective cost. That is a significant reduction from the 4 to 6% vig built into most sportsbook lines.
Place a futures bet on a sportsbook, and you’re locked in until the season ends. Buy a prediction market contract, and you can sell your position any time the market is open. Your assessment changed? Sell. Locked in a profit and want to move your capital elsewhere? Sell. This flexibility transforms a binary bet into a tradeable position.
Sportsbooks offer sports. Prediction markets offer sports, politics, economics, entertainment, weather, crypto, and more. Kalshi alone lists over 10,000 active markets across nine categories.11Kalshi, “Public API market data,” kalshi.com, March 2026 If you have an informed view on Fed interest rate decisions, inflation numbers, or Oscar winners, prediction markets let you trade on that edge.
Prediction markets are not a pure upgrade from sports betting. Pretending otherwise does you a disservice. Here are the real tradeoffs.
Thinner liquidity on non-headline events. Major political races and marquee sporting events attract deep liquidity. A mid-season MLS match or a niche policy contract? You might face wider spreads and slower fills. In sports betting, your sportsbook will always take the other side of your bet at posted odds. On a prediction market exchange, you need another trader to match your order.
Crypto friction on some platforms. Polymarket, the world’s largest prediction market by global volume, runs on USDC (a stablecoin on the Polygon blockchain).12Polymarket, “How to Deposit,” docs.polymarket.com, March 2026 If you’ve never set up a crypto wallet, that’s a real barrier. The learning curve is not trivial for someone used to depositing via debit card at DraftKings.
Pro Tip
If the crypto learning curve concerns you, start with a fiat-funded platform. Kalshi accepts bank transfers, debit cards, Apple Pay, Google Pay, PayPal, Venmo, and Cash App with a $1 minimum deposit.13Kalshi, “Deposit Funds,” help.kalshi.com, March 2026 FanDuel Predicts accepts debit cards and ACH transfers with a $10 minimum.14FanDuel, “Predicts Risk Disclosures,” fanduel.com, March 2026
Sportsbook advantages that still matter. Sportsbooks offer promotional credits, sign-up bonuses, deeper liquidity on individual games, and a mature user experience refined over decades. If you’re a casual bettor who values simplicity and promos over cost efficiency, sportsbooks still deliver.
Capital lockup. Sports bets resolve in hours. Many prediction market contracts resolve in weeks or months. Your capital is tied up longer, which changes how you think about position sizing and bankroll allocation. A $500 position on “Will the Fed cut rates in June?” locks that capital until the Fed announces its decision.
If you’ve been sports betting or playing DFS for any length of time, you already have skills that most prediction market participants lack. The market is young, and a surprising number of traders are making decisions based on gut feeling rather than disciplined analysis.
From sports betting: Your ability to read probability, assess value, and identify when the line is wrong translates directly, and the sports bettor’s guide to prediction markets maps those translations in detail. On a sportsbook, you look for +EV bets where the odds understate the true probability. On a prediction market, you buy contracts priced below your estimated probability, and understanding how prediction market odds work helps you identify where the value sits. Same skill, different interface.
From fantasy sports: DFS grinders bring statistical modeling, correlation analysis, and portfolio construction skills that are rare in prediction markets. Building a DFS lineup under a salary cap is conceptually similar to constructing a portfolio of prediction market positions across uncorrelated events. If you’ve built projection models for NFL player props, you can build probability models for prediction market contracts.
The uncomfortable question: am I just gambling differently? Honest answer: it depends on how you approach it. If you’re buying contracts on gut feeling with no edge, yes, you’re gambling. If you’re applying the same disciplined probability assessment, bankroll management, and expected value calculations you use for sports betting, you’re trading. The platform doesn’t determine the activity. Your process does.
Not every sports bettor needs prediction markets, and not every prediction market needs sports bettors. Here’s a framework based on who you are and what you want.
You should explore prediction markets if you’re a sharp or semi-sharp bettor frustrated by sportsbook vig, closing line value that’s hard to beat, and getting limited on winning accounts. Prediction market exchanges don’t profile winners or restrict accounts. Your edge is welcome.
You should explore prediction markets if you’re a DFS player who enjoys building models and analyzing data across multiple events. Your statistical modeling skills give you a genuine advantage in prediction markets where contract pricing is less efficient than sportsbook odds.
You should wait if you’re a casual bettor who places a few bets per week for entertainment and values a clean, simple experience. Sportsbook apps from FanDuel and DraftKings are still easier to use, and their promotional offers have real value for recreational players.
You should wait if you’re exclusively interested in single-game sports betting with no appetite for politics, economics, or longer-duration events. Sports contract liquidity on prediction market platforms still trails traditional sportsbooks for individual game markets. That gap is closing, but it hasn’t closed yet.
The practical starting point: If you decide to explore, start with one platform and a small amount of capital. Kalshi requires just $1 to start. FanDuel Predicts requires $10. Place a few trades, experience the mechanics, and decide from a position of knowledge rather than theory.
The case for sports bettors and fantasy players exploring prediction markets is straightforward: lower trading costs, the flexibility to sell positions before events resolve, and access to markets well beyond sports. Those are structural advantages, not marketing promises.
The tradeoffs are equally real. Thinner liquidity on smaller events, crypto requirements on some platforms, and a learning curve for exchange mechanics mean prediction markets aren’t a plug-and-play replacement for your sportsbook.
The smart move for most bettors isn’t to choose one over the other. It’s to use both. Keep your sportsbook for individual game bets where liquidity is deep and the experience is polished. Add a prediction market account for longer-duration trades, non-sports events, and situations where the exchange model gives you a cost advantage.
The skills you’ve already built, from reading probability and managing bankroll to spotting value, give you a head start over most prediction market participants.
