French Open trading review: Bet365 leads on uptime and lowest lost turnover

The men’s singles matches at Roland Garros present a unique test of stamina, not just for the players but also for the sportsbooks managing the action. With long rallies, momentum swings and tactical delays, sportsbooks must strike a balance between uptime, pricing sharpness and risk containment.

Our latest analysis examines which operators emerged as the top performers during the 2025 French Open. It utilises live trading data to assess their performance in terms of uptime, acceptance, overrounds and arbitrage exposure.

French Open Bet365 reigns king

Bet365 is the outright leader when it comes to suspensions, with the highest uptime and the lowest lost turnover percentage. Their combination of 96.1% uptime and just 4.5% lost turnover suggests highly responsive risk controls to maintain availability during long and unpredictable five-set encounters.

FanDuel, meanwhile, delivered the most efficient pricing strategy. They combined a competitive 4.8% overround with the lowest exchange arbitrage exposure of any operator at 5.2%. In an environment where pricing errors are quickly punished, this reflects both sharp lines and responsible market-making.

Pinnacle’s unique approach

Pinnacle remains a fascinating outlier. With an industry low 2.3% overround, it remains the most competitive in raw pricing and holds the second lowest exchange arbitrage rate at 6.8%. However, they also posted the lowest uptime by some margin at 77.9% together with the weakest acceptance uptime of 62.8%. Its approach is resulting in superior accuracy at a significant cost of turnover availability.

Unibet provides an unexpected contrast. Despite podium-level uptime at 94.4%, it suffers the highest lost turnover of any operator at 17%. This is more than the lost potential wagering of Pinnacle, whose uptime trails them by a full 16%. This suggests potential issues with their pricing, which in turn is negating the advantage of simply being online.

Reducing lost turnover needs more than just uptime

William Hill’s less-granular odds ladder allows it to avoid a significant number of rejected wagers with an excellent 88.2% acceptance uptime. That said, their unmatched downtime of 1.6% was the third highest in the field, suggesting a possible operational trade-off where less frequent pricing adjustments avoid bet rejection but increase periods of temporary unavailability.

DraftKings continued with an aggressive turnover strategy, which is evident in its solid 93.8% uptime and top half performance in acceptance uptime. However, with an exchange arbitrage rate of 14.9%, it was the most exploitable by a wide margin. This suggests its push to capture more live betting action may have come at the cost of pricing discipline.

Fanatics and Betsson fell into the mid-tier, with performance that neither disappointed nor excelled, while Ladbrokes and Bwin struggled to keep up across multiple metrics, particularly in acceptance uptime and lost turnover.

In a Grand Slam setting where bettor interest peaks, and play is drawn out over five-set marathons, trading desks must find the right rhythm between price agility and execution stability. As the best operators at Roland Garros weren’t just those with low margins, they were those who stayed live the longest while minimising risk.
