The ATP Gstaad Men’s Singles final is set with a resurgent Stefanos Tsitsipas taking on Raphael Collignon at 5:30 am ET at Roy Emerson Arena.

The 24-yer-old Belgian Collignon brings impressive baseline form into the tournament’s final stage, while 27-year-old Greek Tsitsipas aims to channel his big-match experience to hold off the underdog. Below, I have set out my two best data-driven picks for Collignon vs Tsitsipas.

Stefanos Tsitsipas vs Raphael Collignon Picks

Moneyline Pick: Raphael Collignon Moneyline (+113 at Kalshi)

Entering the match as a modest +113 (47-cent) underdog, Raphael Collignon presents excellent value to win the tournament outright. The Belgian’s 2026 profile is no fluke: he is 35-12 overall, 16-3 on clay, and already has two titles this season, while Tsitsipas is 21-15 overall, 9-6 on clay, and titleless in 2026.

The ranking gap backs that up, with Collignon sitting No. 42 with 1,091 points and No. 42 in the year-to-date race with 748 points, compared to Tsitsipas at No. 85 with 740 ranking points and No. 57 in the race with 630 points.

The Elo table adds some nuance but does not force a pick change. Tsitsipas still owns the better clay-specific Elo rating (1841.0, No. 19) than Collignon (1808.1, No. 28), which is the clearest pro-Tsitsipas counterargument. However, Collignon rates higher overall by Elo – 1883.4 and No. 25 compared to Tsitsipas at 1833.4 and No. 31 – and his current clay results are markedly cleaner. His Gstaad run has included wins over Timofey Skatov, Lorenzo Sonego, Valentin Vacherot, and Juan Manuel Cerundolo, and he has repeatedly survived pressure moments rather than simply benefiting from an easy draw.

Pricing is the deciding factor. Kalshi’s 47¢ price on Collignon translates to a +113 moneyline payout. Given Collignon’s stronger 2026 record, superior ranking trajectory, better overall Elo, and 16-3 clay mark this season, plus-money is enough to make him the best bet despite Tsitsipas’ clay-Elo edge.

Game-Total Pick: Over 25.5 (+108 at Kalshi)

The recent match logs for both players, on the whole, strengthens the case for the over. Collignon has gone over 25.5 games in all four of his Gstaad matches: 35 games against Skatov, 26 against Sonego, 38 against Vacherot, and 31 against Cerundolo. Tsitsipas has also played three straight extended matches in Gstaad after a routine opener, going 36 games against Jerome Kym, 27 against Arthur Rinderknech, and 28 against Alexander Shevchenko.

Combined, seven of their eight matches at this event have cleared 25.5 games.

Both men have been pushed on serve, and both have shown enough late-set resilience to make a straight-set blowout less likely. Traditional sportsbooks listed this total heavily juiced at -120, but Kalshi’s 48¢ contract provides a +108 payout. Over 25.5 total games is the strongest secondary wager for the ATP Gstaad title match.
