Fair Value Reasoning:

As of March 15, 2026, the market is significantly mispriced following the Indian Wells semifinals. Daniil Medvedev defeated the previously unbeaten (16-0) Carlos Alcaraz (6-3, 7-6), while Jannik Sinner advanced to the final by beating Zverev. Mainstream bookmakers (e.g., FanDuel, Paddy Power) have now installed Sinner as the clear favorite for the US Open (implied probability ~46-50%), yet he trades at only 29c on Polymarket, while Alcaraz remains overpriced at 43c. This contradicts current form and data. Novak Djokovic's rebound to 7.5c ignores his concerning R16 loss to Jack Draper where he admitted to 'running out of gas'; at 38, his fitness for a best-of-five US Open is suspect. Medvedev, having just beaten the World No. 1 and being a US Open specialist, is critically undervalued at 2.7c.

Divergence

Significant divergence detected. Major external sportsbooks (e.g., Paddy Power, FanDuel) now list Jannik Sinner as the favorite for the 2026 US Open with odds around 2.0 (+100), implying a ~50% probability. However, Sinner trades at only 29c (29%) on Polymarket. Conversely, Alcaraz has slipped behind Sinner in external odds (~+145, 40%), yet remains the heavy favorite on Polymarket at 43c. The prediction market is severely lagging in pricing the impact of the Indian Wells results (Sinner in final, Alcaraz eliminated).
