Sports prediction markets allow users to buy and sell contracts based on whether a future event will happen. A contract might ask whether a team will win, whether a player will reach a statistical threshold, or whether a specific game event will occur.

A prediction market generally uses contract prices that reflect the market’s implied probability. For instance, a contract trading at 65 cents can roughly represent a 65% market-implied chance of the stated outcome.  

What Are Sports Prediction Markets?

Sports prediction markets are platforms where users trade event contracts whose value depends on a sports outcome. 

For example, suppose a contract pays $1 if Team A wins and costs 65 cents. If the contract later settles in Team A’s favor, the holder receives $1 before applicable fees. If Team A loses, the contract can settle at $0.

The price does not necessarily reflect the actual probability of an outcome. Traders should always consider the following aspects –

  • Recent team and player performance
  • Injuries and lineup changes
  • Opponent strength
  • Trading volume and liquidity

A thin market can move sharply after relatively small trades. So, the price alone should not be treated as a guarantee of the outcome. 

Why Are Event Swaps Important?

Event swaps are financial contracts whose value depends on whether a specified event occurs, and their classification is central to the legal dispute.

Operators like Kalshi argue that sports contracts fall under federal derivatives regulation under the Commodity Exchange Act and Dodd-Frank rules. This distinction is important because contracts regulated under federal law may be treated differently from traditional sports bets governed by state gambling laws. The main dispute is whether states can restrict these contracts even when a federal regulator allows them.

Which States Are Restricting Sports Prediction Markets?

Access to sports prediction markets varies by state because regulators and courts have challenged these contracts in several jurisdictions. 

The states involved in disputes or restrictions include Nevada, New Jersey, Massachusetts, Michigan, Washington, Arizona, Connecticut, and Utah.

The legal arguments and proceedings differ by state. Some states have argued that sports event contracts effectively function as sports wagering. Operators maintain that federal law gives the Commodity Futures Trading Commission authority over these markets. 

For users, the practical issue is that a platform available in one state might face restrictions in another.

FAQs

Can You Sell a Prediction Market Contract Before It Settles?

Yes. Depending on the platform and market liquidity, traders may be able to sell their position before the event is settled. The price can change as new information affects market expectations.

What Happens When a Sports Prediction Contract Settles?

The contract settles according to the outcome and the platform’s specified settlement rules. Winning contracts generally pay the stated settlement value, while losing contracts settle at zero.

Why Does Liquidity Matter in Sports Prediction Markets?

Liquidity affects how easily traders can enter or exit a position. A market with low trading activity may experience larger price movements and make it harder to buy or sell at the desired price.
