Prediction Markets vs Sports Betting: What is the Difference?

This guide looks at prediction markets, conventional sportsbooks, and betting exchanges from a commercial perspective. You’ll learn how different revenue models impact operator margins, understand the complex legal fight between state and federal rules, see how advertising rules differ between the models, and find out which sportsbooks are moving into the prediction market space.

What is a Prediction Market?

A prediction market is an online peer-to-peer marketplace where people trade on the outcomes of future events. The main option is an event contract, a specialized financial derivative that’s listed on federally regulated exchanges called Designated Contract Markets (DCMs). These contracts allow participants to trade on real-world outcomes using binary ‘yes’ or ‘no’ choices. Each one is priced between $0.01 and $0.99 based on market probability, and pays $1 if the outcome happens and $0 if it doesn’t.

Traders can freely exit their positions before the event ends to protect profit or cut losses. Our guide, ”How does sports betting work,” can help you understand the big structural differences behind these prices.

Traditional sportsbooks make money by betting against their own customers. By contrast, prediction markets allow users to trade against each other and earn their revenue by charging transaction fees.

Kalshi, Polymarket, and Robinhood are the leading prediction market platforms right now. Kalshi

dominates the regulated U.S. sector; as of April 2026, it accounted for 90% of domestic trading volume.

Polymarket is the main crypto-native platform. Although it has a smaller regulated domestic presence, it holds a large share of global cryptocurrency volume. Robinhood is another important brand in the spacespace. In June 2026, it launched its own CFTC-registered exchange, Rothera (a joint venture with Susquehanna), but it still routes many contracts to Kalshi.

Some of the biggest sportsbooks in the U.S. have also launched prediction markets. For example, FanDuel launched prediction markets in all 50 states in January 2026, but sports event contracts are only available in 18 of them. Other big-name sports betting brands involved in the event contracts space include Fanatics (Fanatics Markets), Underdog, DraftKings (DraftKings Predictions), and PrizePicks.

Prediction Markets vs Sports Betting Differences

The counterparty refers to whoever is on the other side of a wager and is one of the main differences between sportsbooks, prediction markets, and betting exchanges. While traditional sportsbooks take the other side of a bet and lose money if the bettor wins, prediction markets and betting exchanges match participants against one another.

As the comparison table below shows, the CFTC regulates registered U.S. prediction exchanges, state gaming boards oversee sportsbooks, and international gaming commissions regulate betting exchanges.

While all three systems calculate an event’s probability, they have different ways of expressing returns:

• Sportsbook Odds: Displayed as fixed returns on a base stake (e.g., +300 American or 4.00 decimal).
• Prediction Market Contracts: Shown as a live cash price that reflects implied percentage probability (e.g., $0.30 means the implied probability of an event happening is 30%).
• Betting Exchanges: Displayed as peer-to-peer decimal odds with payouts determined by the matched stakeholder’s risk. Exchanges charge a percentage commission on net winnings.

Let’s say that there’s a contract tracking the LA Rams to win the Super Bowl trading at $0.20. A position of 100 contracts carries an aggregate asset value of $20. If the Rams win the Vince Lombardi Trophy, the contracts settle at $1 each, which means a return of $80 before fees. This corresponds to decimal odds of 5.00 or American odds of +400 on a sportsbook or betting exchange.

Liquidity and Execution

A quoted price is only good value if there’s enough liquidity to take advantage. If a prediction market offers 500 contracts at $0.60, for example, a 2,000-contract order will have price slippage as the remaining volume moves into higher prices on the order book.

Platforms have different ways of handling execution limits:

• Prediction Exchanges: Disclose thin liquidity by showing resting quantities and order book depth. This allows users to see the available depth before making a trade.
• Sportsbooks: Manage capacity by setting hard limits on the total risk they’re willing to accept. If you’re figuring out how to be a bookie, managing this depth and capacity is a crucial part of the business.
• Betting Exchanges: Like prediction markets, these show order book depth. Users can see the available volume, but will need to wait for a price to get matched if there isn’t enough liquidity in the market.

How Betting Exchanges, Prediction Markets, and Sports Betting Sites Make Money

The way these platforms make a profit is another important difference between prediction markets and sports betting sites, with exchanges having their own means of earning:

• Prediction Markets: Charge trading fees per contract and carry no outcome risk.
• Betting Exchanges: Peer-to-peer betting networks like Betfair charge commission on net winnings.
• Sportsbooks: Build vig into their odds and earn revenue from stakes accepted minus money paid out.

Prediction Market vs Betting Exchange vs Sportsbook Odds

Subtracting the exchange’s winning commission, a prediction market’s trading fees, or a standard sportsbook’s vig reveals the real value of the odds provided by a platform.

Let’s say there’s an NBA game featuring the Pistons and the Spurs, and the market evaluates the Pistons as having a 50% implied probability of winning. Here’s what a successful $100 position looks like in terms of return on all three sports betting business models mentioned above based on fair market pricing:

Since prediction markets and betting exchanges operate on peer-to-peer architectures, they don’t have house edges and typically deliver higher payouts. While traditional sportsbooks can’t win on pricing alone, they can sustain market share through a variety of methods. These include large prop libraries, generous sign-up bonuses and regular promotions, and Same Game Parlays (SGPs).

Who’s in Charge of Sports Betting and Prediction Market Regulation, and Why It Matters

The Commodity Futures Trading Commission (CFTC) oversees registered U.S. prediction market exchanges. Commercial sportsbooks are regulated by individual state gaming control boards or tribal authorities that operate under tribal-state compacts. These platforms are strictly bound by local retail and online gambling laws.

While platforms such as Kalshi and Polymarket US are registered as federally supervised Designated Contract Markets (DCMs), the exact legal classification of their listings remains heavily contested.

For example, Kalshi argues that its sports contracts are ‘swaps’ under the Commodity Exchange Act (CEA). However, federal courts, such as the Sixth Circuit, have rejected this claim, ruling that the platform hasn’t proved its sports-based event contracts legally qualify as swaps.

Prediction markets argue that federal preemption applies. In simple terms, they claim that federal financial laws are more powerful than local state gambling rules. They believe individual states don’t have the legal right to ban any exchange with a federal license.

State regulators are fighting back, however. This ongoing legal battle has split federal courts across the United States, creating a 2-1 circuit split against Kalshi:

• April 6, 2026: The Third Circuit protected Kalshi from New Jersey regulators. It ruled that sports event contracts are swaps that fall under federal jurisdiction.
• August 28, 2026: The Ninth Circuit ruled against Kalshi in Nevada. It held that the platform failed to prove its sports contracts were exempt from state-level gambling oversight.
• September 25, 2026: The Sixth Circuit ruled against Kalshi, stating that federal financial laws don’t overrule the local gambling bans in Ohio or Tennessee.

State-level enforcement is also intensifying. On September 3, 2026, a Michigan court ordered Kalshi to geofence immediately and halt its sports contracts within the state. Then, on September 24, New York State officially sued Polymarket US, alleging that the platform was running an unlicensed, illegal gambling operation.

Until the Supreme Court makes things clear, no one can safely assume that a federal financial license protects a platform from local state gambling rules. That said, we may get a final answer sooner rather than later. On September 2, 2026, New Jersey filed a cert petition, which is a formal request asking the Supreme Court to review the Third Circuit’s decision.

Are Prediction Markets Legal Where Sportsbooks Aren’t?

Yes, legal differences mean that prediction markets are open for business in locations where traditional sportsbooks are banned. Mapping out where sports betting is legal reveals a fragmented market. At present, 20 states prohibit mobile or online sportsbooks, and 11 forbid any form of sports betting. The following 10 states don’t have mobile or retail sportsbooks, but broadly let residents trade on prediction platforms:

• Alabama
• Alaska
• California
• Georgia
• Hawaii
• Idaho
• Minnesota
• Oklahoma
• South Carolina
• Texas

Platforms like Kalshi argue they are financial exchanges, not gambling sites. As a result, residents of large non-sportsbook markets such as Texas and California can currently trade sports contracts, although that access depends on how the federal-versus-state fight is resolved. On the flip side, Utah doesn’t allow prediction markets or sportsbooks because of its strict state laws.

Residents of states such as Ohio, Tennessee, and Nevada can’t legally trade sports contracts on prediction markets, but they can use online sportsbooks. This situation is a direct result of recent federal and state developments, such as those outlined above.

What States Could Change Next?

The boundaries are moving quickly, and the answer to the ‘are prediction markets legal everywhere’ question isn’t straightforward, as some states are pushing back. Maryland regulators are arguing that sports event contracts are unlicensed sports bets. This case is currently before the Fourth Circuit Court of Appeals.

The Ohio Casino Control Commission has proposed a $5 million fine against Kalshi for operating without a state license, and state regulators are arguing for a full blackout. Rhode Island is another state currently involved in lawsuits against prediction platforms.

How Prediction Markets Compete With Sportsbooks for the Same Player

Major sportsbooks, such as FanDuel, DraftKings, and Fanatics, see event contracts as a powerful customer acquisition channel in states that prohibit sports betting. It’s this geographic fallback that provides the real answer to whether prediction products are a competitor or a channel.

For instance, FanDuel expanded its standalone app across all 50 states but restricted its sports contracts to large markets such as California and Texas, where its main sports betting app isn’t allowed. In states where sportsbooks are legal, FanDuel restricts its prediction app to finance and pop culture.

Through products such as DraftKings Predictions and Fanatics Markets, sportsbooks use federal financial frameworks to build large player databases in non-gambling states.

Meanwhile, user behavior plays a big role in determining the type of bettors most likely to switch. Sharps (high-skill, high-volume bettors) are moving away from sportsbooks because of issues like low betting limits and account bans. Prediction markets are more winner-friendly, have no built-in vig, and allow players to use automated trading bots.

Recreational bettors want high-variance, high-potential payout options like Same Game Parlays (SGPs) and player props. Prediction markets like Kalshi offer parlay-style ‘combos,’ but use a multi-step Request for Quote (RFQ) system that makes trades less straightforward than SGPs. Since casual players value convenience, they’re more likely to stick with sportsbooks.

Legal Restrictions: Obstacle or Future Opportunity?

In states where sportsbooks aren’t legal, prediction markets are the main regulated way to trade on sports. They can condition millions of sports fans to use digital wallets to trade sports outcomes. If a state such as California or Texas ever legalizes traditional sportsbooks, operators will have to compete against established user habits.

However, sportsbooks could also use prediction markets to their advantage. As these markets attract top mathematical minds and have high betting limits, their contract prices arguably represent the truest real-world probability of an event happening. Conventional sportsbooks can then use this data to sharpen their odds and manage liability.

Ultimately, for modern gaming operators, prediction markets are competitors and acquisition channels. They are a competitor for high-volume sharp bettors who want to avoid the house vig. Yet, they also act as a top-of-funnel channel to legally acquire and nurture user databases in states where traditional online sportsbooks are outlawed.

The Search Behavior Shift: New Keywords for Operators

Consumer search behavior is changing as the line between prediction markets and sports betting becomes more blurred. Rather than looking for standard gambling terms like “NFL moneylines,” users are increasingly searching for direct platform comparisons.

So, gaming operators must now track different target keywords.These include comparison keywords like “Kalshi vs DraftKings” and “prediction markets vs sportsbooks.” Users are also looking for terms focused on market mechanics such as “zero-vig betting” and “event contract apps.”

From an operator’s point of view, marketing teams must move away from standard gaming keywords and focus on comparison-based terms. Doing so enables them to capture high-value user intent early on, so they steer prediction traders into their ecosystem before a rival does.

What Are the Advertising Rules for Prediction Markets vs Sports Betting?

The legal definitions behind these platforms lead to big differences in advertising rules in sports betting vs prediction markets. Traditional sportsbooks must meet state-by-state gaming laws, while prediction markets work as financial exchanges under federal financial frameworks.

Ad platforms add another layer: Google, for example, only accepts prediction market ads from certified, CFTC-registered exchanges and blocks them entirely in Nevada, Ohio, Michigan, and New York.

Affiliate Disclosure & Compliance Considerations

The regulatory divide also changes how marketing affiliates operate. Creating the right sports betting marketing strategies means learning about complex gambling marketing laws.

Sportsbook affiliates can use tracking links but need to secure individual state vendor registrations or affiliate licenses. They must also use geo-targeting software to block restricted states. All content must prominently display state-specific responsible gambling messaging, helpline numbers, and age 21+ compliance warnings.

Prediction market affiliates must follow CFTC and National Futures Association (NFA) rules, which mandate clear disclosures regarding the risk of capital loss when trading derivatives. Standard consumer endorsement rules from the FTC also apply. It’s worth noting that prediction markets typically feature an age-18+ threshold, giving them a much larger demographic for ad compliance than the sports betting or gambling sectors.

Historically, this gave prediction market affiliates an advantage: content about event contracts was treated as financial commentary rather than gambling solicitation, so it sat outside state gaming board oversight.

Yet, following the Sixth and Ninth Circuit court rulings, this is no longer a clear advantage. As federal courts have empowered individual states to enforce local gambling laws against sports contracts, affiliates now face a major compliance risk. If a state decides to reclassify an event contract as gambling, any affiliate content that promotes it it could fall under state gaming board oversight, with potential penalties for unlicensed solicitation.
