The Arizona Diamondbacks travel to Citi Field to face the New York Mets on Tuesday, April 7, 2026, at 4:10 PM. As both teams look to find their rhythm in the early stages of the 2026 season, you can engage with the action on Kalshi, a premier legal US prediction market. By using the Kalshi promo code WSN, new traders can get a $10 bonus when you trade $100 worth of contracts. This offer provides a $10 bonus after trading your first 100 contracts, allowing you to take positions on the game's outcome through a regulated exchange.

If you are new to prediction markets, think of them as a financial exchange rather than a traditional sports platform. On Kalshi, you aren't placing a bet; instead, you are trading event contracts based on "Yes" or "No" outcomes. Each contract's price fluctuates between $0.01 and $0.99, reflecting the market's aggregate belief in the probability of that event occurring. If your prediction is correct, the contract settles at $1.00.
The Kalshi promo code WSN is designed to help new users get started on the platform. By entering the Kalshi promo code WSN during registration, you become eligible for a $10 bonus once you have traded a total of 100 contracts. This allows you to build a portfolio of positions across various MLB markets or other economic events.

The matchup on April 7, 2026, features a compelling pitching duel. The Arizona Diamondbacks are expected to start Zac Gallen, who has maintained a solid 3.60 ERA through his first two starts of the season. The New York Mets counter with Freddy Peralta, who sits at 1-0 with a 4.35 ERA. With temperatures at Citi Field expected to be a chilly 41°F with high winds, the market is currently adjusting for a potential low-scoring affair.
| Market | Option | Probability | Yes Price |
|---|---|---|---|
| Mets | Yes | 54% | $0.54 |
| Diamondbacks | Yes | 46% | $0.46 |
| Total Runs Over 7.5 | Yes | 48% | $0.48 |

Trading on Kalshi is distinct because you are buying and selling shares of an outcome. Unlike a bookmaker that sets a fixed price, Kalshi is an exchange where traders interact with one another. If you believe the Mets will win, you buy the "Yes" contract. If the price is $0.54, you are essentially paying 54 cents for a contract that will be worth $1.00 if the Mets succeed.
You can exit your position at any time before the game ends. If the Mets take an early lead, the price of your "Yes" contract might rise to $0.80, allowing you to sell and realize a gain immediately without waiting for the final out. This flexibility is a hallmark of the Kalshi experience.
