ATP Challenger market beaters: win rate against closing odds

PickFinder logo

PickFinder Team•Updated:

Jan Kumstat has beaten the closing tennis odds by the most on the ATP Challenger tour over the last 52 weeks: 78.8% wins against 55.2% implied, over 33 matches. Gilles Arnaud Bailly has lagged them the most, 33.3% against 52.3%. Most of this looks like noise: 11 of 282 players sit outside the noise band where chance alone would put about 12.8, and a player's gap in the first 26 weeks correlates -0.03 with the last 26.

How good is the closing price?

Each band is the favorite's no-vig chance at the close. Power de-vig tracks the real win rate. Proportional de-vig, the common shortcut, understates favorites, which would make every heavy favorite look like a market beater. This page uses power.

Using market beaters on a prop

  1. Read the gap

    Jan Kumstat won 78.8% against 55.2% implied, a gap of +23.6 points over 33 matches. The noise band for that sample is ±16.5, so a gap has to be that big before it stands out at all.

  2. Split favorites and underdogs

    Jan Kumstat is 18-2 as a favorite and 8-5 as an underdog. Gilles Arnaud Bailly is 7-7 and 3-13. It shows where a record came from.

  3. Treat it as context for the price

    This explains what has happened, not what comes next. A player's gap correlates -0.03 from one half of the window to the next, across 232 players. Don't read a big gap as a reason to bet.

  4. Start from the close

    Favorites priced at 80% to 90% won 85.4% of 1328 matches against 84.4% implied by the power de-vig. The closing price is hard to beat, so treat it as your starting point. Today's line and the hit rate against it are in PickFinder.

How this is counted

Counts finished singles matches with a closing moneyline on both players, Nov 2, 2025 to Nov 2, 2026. 93% of prices are Pinnacle's, and the rest come from another major book. Implied % removes the vig with a power de-vig, because it matches real win rates. The proportional shortcut understates favorites: at 80% to 90% it gives 82.2%, power gives 84.4%, and they actually won 85.4%. Gap is win % minus average implied %. The noise band is two standard deviations of what those prices would produce by chance over that many matches. Beyond noise means the gap is outside it, and with this many players some will be by luck, which is why the page shows the count. Retired matches and walkovers are left out. Only ATP Challenger matches count here, qualifying included. Main tour matches have their own view. A player needs 30+ priced matches.

Market beaters FAQ

Who has beaten the market the most on the ATP Challenger tour?

Jan Kumstat: 78.8% wins against 55.2% implied over 33 matches, a gap of +23.6 points with a noise band of ±16.5.

Who has been most overrated on the ATP Challenger tour?

Gilles Arnaud Bailly: 33.3% wins against 52.3% implied over 30 matches, a gap of -19.0 points.

Does beating the market carry over?

Not much. A player's gap in the first 26 weeks correlates -0.03 with the last 26 across 232 players. 11 of 282 players sit outside the noise band, and chance alone would put about 12.8 there.

Are closing tennis odds accurate?

Close to it, after a power de-vig. Favorites priced at 80% to 90% won 85.4% of 1328 matches against 84.4% implied.

Why not use the simple proportional de-vig?

It understates favorites. At 80% to 90% it gives 82.2% against a real win rate of 85.4%, which would make every heavy favorite look like a market beater.
