What US Open markets does Kalshi have?
Kalshi quotes every market between 1¢ and 99¢, with the price doubling as the market's implied probability. A 24¢ contract pays $1 if it lands, so it's the exchange version of roughly +317 at a sportsbook.
The two headline outright markets for the tournament:
Men's Tournament Winner – Carlos Alcaraz has been the market leader since Jannik Sinner's withdrawal, with Alexander Zverev the clear second choice and daylight back to the rest. This is comfortably the busier of the two boards, and you can find the prices below.
| Player | Chance | Yes | No |
|---|---|---|---|
| Carlos Alcaraz | 35% | 35¢ | 66¢ |
| Alexander Zverev | 22% | 22¢ | 79¢ |
| Ben Shelton | 9% | 9¢ | 92¢ |
With Novak Djokovic's exit, the tournament is seemingly Alcaraz’s to win, without a challenger, with the Serbian veteran having headed home. Ben Shelton carries the home crowd's hopes, yet the market is moving away from him, his price not improving even across the first few days.
Women's Tournament Winner – Aryna Sabalenka has led throughout as she chases a third straight title, with Coco Gauff and Iga Swiatek close behind.
| Player | Chance | Yes | No |
|---|---|---|---|
| Aryna Sabalenka | 24% | 24¢ | 77¢ |
| Coco Gauff | 19% | 19¢ | 82¢ |
| Iga Swiatek | 16% | 16¢ | 85¢ |
Coco Gauff exploded on this scene a few years later and returned to try and take the crown for herself. Yet in her way, the women’s No.1 Sabalenka stands, yet she continues to drift in price, as she has not made a final since March.
The hope of seeing some success for Team USA in this tourney rests with Gauff instead of Shelton this time out, as Alcaraz continues to headline the Kalshi US Open markets. Your $25 from the Kalshi promo code ACTION could go a long way on Gauff, with returns comfortably $100+.
Is the New $25 Flat Bonus Better Than the Old $500 Offer?
Kalshi has had two prediction market promos in the last few months; if you checked this offer out recently, a few things may have changed. Make sure the Kalshi promo code ACTION is the offer you want to claim with our easy explanation below.
| Old offer | New offer | |
|---|---|---|
| Structure | Randomised | Flat |
| Range | $15–$500 | $25 |
| Typical outcome | $15 for most users | $25 for all users |
| Certainty | None | Total |
Yes, the old ceiling towered above $25. But almost nobody reached it. Prior testing found most users landing on the $15 floor, which means the typical trader now nets $10 more than before, guaranteed.
A 100% shot at $25 beats a sliver of a chance at $500 alongside a strong likelihood of $15. The Kalshi promo code ACTION swaps a lottery ticket for a sure thing.
