The Oklahoma City Thunder look to continue their dominant postseason run against the Los Angeles Lakers this Monday, May 11, 2026. As this high stakes Western Conference Semifinal matchup heads to Game 4, you can participate in the action via Kalshi, a regulated prediction market. By using the Kalshi promo code WSN, new traders can Get a $10 Bonus When You Trade $100. This offer allows you to receive a $10 bonus after trading your first 100 contracts on the platform, providing a unique way to engage with the Thunder vs. Lakers game.

Kalshi operates differently than a traditional sportsbook. Instead of taking a position against a house, you are trading event contracts with other participants. Each contract is a "Yes" or "No" proposition on a specific outcome, such as "Will the Los Angeles Lakers win Game 4?" The price of a contract ranges between $0.01 and $0.99, reflecting the market's aggregate belief in the probability of that event occurring.
When you use the Kalshi promo code WSN, you are entering a federally regulated exchange where you can buy and sell these positions just like stocks. Once you trade your first 100 contracts, you qualify for the $10 bonus.

| Market | Option | Probability | Yes Price |

Trading on Kalshi is the act of buying or selling "Yes" or "No" shares in a specific event. Each contract pays out exactly $1.00 if the outcome is correct and $0.00 if it is not. Your profit or loss is determined by the difference between the price you paid for the contract and the final $1.00 payout (or the price at which you sold the contract before the event ended). This structure makes it a pure prediction market, where the "odds" are simply the current market price of the contract.
