What Are Prediction Markets and How Are They Different From Sportsbooks?

Sports betting is changing. You might have started hearing about “prediction markets” popping up alongside the DraftKings and FanDuel ads you already know. But what exactly are prediction markets? Are they just another way to bet on sports? And why does everyone seem to be fighting about them?

Let’s break it all down from scratch.

First, a Quick Refresher on How Sportsbooks Work

A sportsbook (think DraftKings, FanDuel, BetMGM) is an online platform where you place bets on sports. You pick a team, choose your bet type — moneyline, spread, total points — and the sportsbook gives you odds. Those odds tell you how much you’ll win if you’re right.

For example, if the Chiefs are -150 to win a game, you’d need to bet $150 to win $100. If they’re +130, a $100 bet wins you $130. The sportsbook sets those odds and takes a cut — called the “vig” or “juice” — built into the odds.

One more key thing: you’re betting against the house. The sportsbook takes the other side of every wager.

So What Is a Prediction Market?

A prediction market is a platform where you buy and sell contracts based on the outcome of real-world events — including sports games.

Here’s the simplest way to think about it: imagine a contract that says “The Chiefs will win the Super Bowl.” That contract is worth exactly $1.00 if the Chiefs win, and $0.00 if they don’t. The price of that contract fluctuates between $0 and $1 based on what traders think the probability is.

If the market thinks the Chiefs have a 65% chance to win, the contract trades at about $0.65. You can buy it for $0.65, and if the Chiefs win, you collect $1.00 — a $0.35 profit. If they lose, you’re out $0.65.

The big platforms in this space right now are Kalshi and Polymarket. Think of them less like a casino and more like a stock exchange — except instead of buying shares of Apple, you’re buying contracts on whether the Eagles will win on Sunday.

The Biggest Difference: Who Regulates Them

This is the part that matters most, and it’s why prediction markets have become such a hot-button issue in 2026.

Sportsbooks are regulated by individual states. Each state decides whether to legalize sports betting, sets the rules, and licenses the operators. That’s why sports betting is available in some states but not others. As of 2026, roughly half the country has legalized online sports betting.

Prediction markets, on the other hand, are regulated by the federal government — specifically, the Commodity Futures Trading Commission (CFTC). The CFTC normally oversees things like oil futures and grain contracts. It views prediction market contracts as financial derivatives (similar to a futures contract), not gambling.

What does that mean for you? It means prediction markets are technically available in all 50 states — even in California and Texas, where you can’t legally use DraftKings for sports betting. That nationwide access is a huge competitive advantage, and it’s exactly why traditional sportsbooks are freaking out.

How Payouts Work: Contracts vs. Odds

With a sportsbook, your payout is determined by the odds at the time you place your bet. If you bet $50 on a team at +200, you win $100 regardless of what odds do after that.

With a prediction market, you can actually trade in and out before the event settles. If you buy a Chiefs contract at $0.60 and it rises to $0.85 as the game approaches, you can sell your contract and lock in that $0.25 gain — without even waiting for the final whistle. It’s more like trading stocks than placing a sports bet.

This flexibility is something totally new for most sports fans. It’s also why some people argue prediction markets are a financial product, not gambling.

What They Have in Common

Let’s be real: at the end of the day, both products let you put money down on whether your team wins. The experience feels similar. Both platforms show you prices that reflect how likely an outcome is. Both pay you if you’re right and cost you if you’re wrong.

The fundamental experience — watching a game with money on it — is the same. The mechanics under the hood are just different.

The Debate: Is a Prediction Market Just Gambling with a Fancy Name?

That’s literally what Congress is debating right now. In March 2026, senators introduced the Prediction Markets Are Gambling Act, arguing that sports contracts on platforms like Kalshi are just sports bets, regardless of what you call them.

Kalshi disagrees, saying they operate as a federal commodity exchange and that calling it gambling misunderstands what their product is. Courts across the country are split on the question too — some have ruled in Kalshi’s favor, others have sided with states trying to shut them down.

The Bottom Line for Beginners

Here’s what you actually need to know:

• Sportsbooks (DraftKings, FanDuel): Available in ~28 states, regulated by each state, you bet with traditional odds against the house.
• Prediction markets (Kalshi, Polymarket): Available in all 50 states, federally regulated by CFTC, you buy/sell contracts with prices between $0 and $1.
• Both let you put money on sports outcomes. The legal framework and product structure are just different.
• The regulatory battle between the two is far from over — and the winner will shape what sports betting looks like for the next decade.
