Krejcikova vs Andreeva Set 1 Tops 8.5 Games at Wimbledon | Lines.com

Barbora Krejcikova and Mirra Andreeva delivered exactly what the over crowd wanted. The opening set of their second-round Wimbledon match on July 1, 2026 ran to 10 games, clearing the 8.5-game threshold and resolving the primary Polymarket contract at YES. Krejcikova eventually won the match 4-6, 7-5, 6-4 in two hours and 46 minutes on Centre Court.

The market opened this set-total line at roughly 63 percent in favor of OVER. By the time the match reached its climax, the contract had surged to 100 percent. Two whale traders who sold at 85.8 cents and 68.1 cents, banking a collective $137,549 on UNDER territory, watched the line move entirely against them. The $396,504 total volume confirmed genuine market conviction behind the outcome.

Set 1 Between Krejcikova and Andreeva Ran 10 Games

Andreeva, the 19-year-old reigning French Open champion and fifth seed, took the first set 6-4. The set required 10 total games before Andreeva closed it out. That single number, 10, is the one that mattered for the 8.5-game over-under. The line cleared by a full game and a half, not a nail-biting margin.

The broader match turned into a Centre Court classic. Krejcikova, the 2024 Wimbledon champion, trailed after Set 1 and faced a fierce Andreeva in Set 2. Krejcikova took Set 2 7-5 and Set 3 6-4, saving the match on her seventh match point, aided by a net cord on the final point. Andreeva had saved the first six match points before that decisive moment ended her run.

The final-hours market reflected the live scoring perfectly. As Set 1 ticked past nine games, the contract price accelerated toward 1.00. The 38-percentage-point jump in 24 hours captured both the live resolution and the rapid repricing that follows when a game-count line is settled in real time.

How the Market Priced This Set-Total Line

The market opened the Set 1 O/U 8.5 contract at 63 percent in favor of OVER. That starting price reflected genuine uncertainty. Grass-court first sets in WTA matches tend to be tight, and a 63 percent lean on OVER is a modest lean, not a lock. The market was directionally correct but left meaningful room for the UNDER.

The $396,504 in total volume, with $395,685 of that arriving in the 24 hours surrounding resolution, shows traders were active and engaged. The $142,221 in liquidity gave the market enough depth to price the line with reasonable accuracy. The opening price of 63 percent versus an outcome that went 10 games tells you the market slightly underpriced the OVER at the start.

MARKET PERFORMANCE SUMMARY

• Resolution Outcome: YES, Set 1 exceeded 8.5 games (10 games played)
• Article-Time Probability: 100% (market resolved)
• Opening Market Price: 63%
• Total Volume: $396,504
• Market Assessment: Underpriced YES at open. Directionally correct, but 63% opening left meaningful edge on the table.

What the Krejcikova-Andreeva Match Means Going Forward

Krejcikova advances to the third round at Wimbledon 2026, where she faces fellow Czech Nikola Bartunkova in an all-Czech matchup. The 2024 champion is alive in the draw, and the victory over a top-five opponent on Centre Court carries genuine weight in the tournament picture. Krejcikova’s market correlation with the 2026 Women’s Wimbledon Winner market now becomes relevant.

For prediction market traders, this match illustrated a structural truth about set-total lines. Two quality players with contrasting styles, one grass specialist and one clay champion transitioning to grass, tend to produce extended baseline exchanges. The over often holds in these stylistic mismatches. A 63 percent open looks conservative in hindsight.

• Krejcikova’s path to the Wimbledon quarterfinal now runs through the bottom half of the draw, where her experience as a defending champion matters.
• Andreeva, 19, heads to the North American hard-court swing after her run at Roland-Garros and a tough exit here, accumulating major-tournament experience at a rapid pace.
• The Set 2 O/U markets (8.5 and 9.5) also resolved OVER, as the second set ran 12 games (7-5), reinforcing the pattern of extended sets in this matchup.
• Total match games reached 32 across three sets, clearing every match total line (21.5, 22.5, and 23.5) offered in the related markets cluster.

LINES RESOLUTION VERDICT

OVER CONFIRMED

The market opened at 63 percent on OVER 8.5 first-set games and the set delivered 10, giving traders who bought early a comfortable margin and leaving the two large whale sellers significantly offside.

What the market showed: A 63% opening price correctly leaned OVER but underpriced the true probability. The contract closed at 100% after a 10-game opening set between Krejcikova and Andreeva made the result unambiguous.
