Wimbledon ATP: Jenson Brooksby vs Ignacio Buse

Platform comparison

Market context

The upcoming Wimbledon Men’s Singles Round 2 match pits Jenson Brooksby against Ignacio Buse on 1 July 2026 at 6:00 AM ET, with the prediction market currently implying a 68% chance that Brooksby advances. This crowd-implied probability sits notably higher than independent analytics models, which estimate Brooksby’s win chance at 56–57.4% [1][3]. Australian bookmakers list Brooksby at $1.66 and Buse at $2.20, translating to implied probabilities of roughly 60% and 45% respectively [1]. In contrast, US moneyline odds show Brooksby at –145 and Buse at +132, aligning closer to the 57% modelled probability [3].

Historical precedents from recent Wimbledon rounds suggest that crowd-implied probabilities often overshoot modelled win rates when a player is favoured on paper but lacks dominant recent form. Traders should monitor official tournament updates, including potential weather delays or injury reports, as these can shift settlement outcomes significantly. The All England Lawn Tennis and Croquet Club has confirmed the match is scheduled for 01:00 local time, with live coverage available via Tennis.com and Sofascore [2][6]. A key catalyst is the first-set outcome, where TAB offers Brooksby at $1.80 and Buse at $2.00, hinting at a tighter contest than the head-to-head odds imply [1].

Platforms diverge sharply on this market: Polymarket and Kalshi use decimal odds and implied probabilities, while Betfair and Smarkets emphasise fee structures and KYC reach. Kalshi’s 2% fee contrasts with Betfair’s variable commission, affecting net returns for traders. With settlement ending 8 July 2026, traders must weigh the 68% crowd signal against the 57% model consensus, noting that cancellations or delays beyond seven days reset the market to 50–50 [1].
