Trade on U.S. Open Golf Using Kalshi
One of the best ways to trade on the U.S. Open is to target the first-round leader market. There's value all the way down the board, as even the favorites have less than a five percent chance to win. The Action Network experts like Jon Rahm to lead after the first round of the U.S. Open.
Check out what happens if you make a $10 trade on this prediction using the Kalshi promo code ACTION.
U.S. Open First Round Leader: Jon Rahm (2.3%): This course demands elite driving, as long, penal fairways and thick fescue punish any miss and make approach shots extremely difficult. Jon Rahm fits that setup well, entering in strong form with two wins and five runner-up finishes in his last 11 starts and ranking among the best drivers of the ball, including sixth in strokes gained off the tee at the PGA Championship.
If Rahm leads after the first round of the U.S. Open, you earn a payout of over $400 along with your $10 bonus. Even if your trade loses, you still walk away with a $10 bonus.
Don't miss your chance to claim a $10 welcome bonus with the Kalshi referral code ACTION. Trade on Scottie Scheffler, Rory McIlroy, or any player in the U.S. Open.
