The US Open closes the Grand Slam season: 128 players, on hard court, in New York from late August. Its winner market opens weeks before the first serve. It's one of the more readable futures in sport — as long as you keep a cool head.
A handful of favourites, a long tail of hope
Elite tennis is concentrated: a few players hold most of the real probability, and the rest of the draw is priced on hope. Always convert: returns of 2.75 on a favourite are about 36% (1 ÷ 2.75). A player at 26.00? Under 4%. Your only question: is this price more generous than your own estimate?
Tennis rewards line-shopping
A tennis quirk: for the same player, prices differ meaningfully from one broker to the next. Consistently taking the best available price — line-shopping — lifts your long-run return without changing a single one of your picks. Over a season, that's often the difference between winning and losing.
The longshot tax
As on any long-term market, extreme longshots are overpriced: the favourite–longshot bias means the shock winner at 40 pays, on average, less than its real probability. The small dream ticket is precisely the one that costs the most over time.
