Matteo Berrettini is an Italian professional tennis player competing on the ATP Tour. The 2026 US Open Men's singles championship will be held at the USTA Billie Jean King National Tennis Center in New York from August 31 to September 13. Berrettini has competed at the US Open multiple times but has not yet captured the title. At 1% YES odds, the market reflects that traders view Berrettini as a significant long-shot to win this Grand Slam. The US Open is one of tennis's four Grand Slam tournaments and draws the world's top-ranked players. With such low odds, the market prices in substantial competition from higher-ranked contenders and tournament favorites. The current price implies the market expects other players to dominate the draw. Berrettini would need to navigate a competitive field and maintain peak form throughout all rounds to reach and win the final. The 1% probability suggests the market assigns low conviction to this outcome relative to frontrunners. Over the past 24 hours, this market generated $47,900 in trading volume with $27,163 in liquidity, indicating ongoing interest from traders exploring various odds levels.
