What could influence prediction markets for the U.S. Open?
Market sentiment on the best prediction market sites is sure to change when the tournament kicks off. This change is likely to be influenced by:
- Course conditions: The U.S. Open and hard tests are synonymous in golf. This event has traditionally featured fast greens, narrow fairways, and thick rough. Under these conditions, expert player skills make all the difference.
- Recent player form: A week before the event, Scottie Scheffler and Rory McIlroy are already the frontrunners. Each of them is having a stellar season so far, and this could be further extended by good performances at the U.S. Open. Expect this to have a major influence on the event in the sports prediction markets, including Kalshi’s.
- Short-game performance: The U.S. Open’s course notoriety calls for a different approach to the short game. When the greens become harder to hit, strong-short game specialists can gain an edge and even go on to win.
