Unlike traditional platforms where you back a team to win under a static line, Kalshi operates as a financial exchange. On this network, you trade financial contracts based on real-world outcomes. Each contract functions like a mini share that resolves to either $1.00 if the event happens or $0.00 if it does not. The current market price of a contract reflects the consensus implied probability of that outcome occurring.
The signup promotion is straightforward. When you open a new account and apply the Kalshi promo code WSN, you qualify for a trading credit. Once you trade your first 100 contracts on any available market, Kalshi will automatically credit your account balance with a $10 bonus after trading your first 100 contracts. This provides an excellent entry point to learn the mechanics of supply and demand trading without relying on old-school systems.

The June 4 game features a pitching matchup between right-handers Jared Jones of the Pirates and Kai-Wei Teng of the Astros. Pittsburgh comes into the game carrying a hot momentum streak, while Houston looks to defend their home field at Daikin Park. This game presents several liquid contract markets on the exchange floor.
| Market | Option | Implied Probability | Yes Price |
|---|---|---|---|
| Houston Astros | Yes | 50.8% | $0.51 |
| Pittsburgh Pirates | Yes | 49.2% | $0.49 |
Implied probabilities and contract prices fluctuate dynamically up until game time based on user trading volume and market sentiment.

Trading on Kalshi is fundamentally different from using a traditional retail sportsbook. Because Kalshi is structured as a financial exchange rather than a betting shop, users buy and sell positions directly with one another.
If you believe the Houston Astros will win on June 4, you buy the "Yes" contract. If the market price is $0.51, you pay 51 cents to own that contract. If the Astros win, your contract settles at $1.00, yielding a profit of 49 cents per contract. If they lose, the contract settles at $0.00.
A major advantage of this financial structure is the ability to manage your risk dynamically. You do not have to hold your contracts until the final inning. If the Astros take an early lead, the price of your contract might rise from $0.51 to $0.80. You can sell your positions early to lock in immediate profits and minimize your exposure to late-game rallies.

Responsible Risk Management
Always practice responsible risk management when utilizing financial exchanges. Trading involves financial risk, and it is crucial to only invest capital that you are prepared to lose. Set strict limits on your portfolio exposure and monitor your active contracts closely.
