The WTA Finals lost their defending champion before the first ball was struck at Indian Wells Tennis Garden, and that changes the entire outlook for anyone trading futures this week.
Elena Rybakina, the world No. 1 who won the Australian Open and U.S. Open this season, withdrew from the event Saturday with a viral illness. Marta Kostyuk got the call as her replacement with about a day to prepare, and it showed in Sunday’s opener as Wimbledon champion Linda Noskova handled her 6-2, 6-4.
Coco Gauff followed with a grinder against Jessica Pegula, letting a match point slip away in a second-set tiebreak before rolling through the third for a 6-4, 6-7 (5), 6-2 win. The 2024 champion gets Noskova next on Tuesday with control of Group 1 up for grabs.
Group 2 opened Monday, and the two favorites held serve. Aryna Sabalenka survived Karolina Muchova 7-6 (2), 7-5, while French Open champion Mirra Andreeva needed just 70 minutes to dismantle Elina Svitolina 6-4, 6-0. That sets up a Sabalenka-Andreeva showdown Wednesday that could decide who tops the group.
With Rybakina out, Sabalenka is the natural name to beat. She won this same event in March, but she has also come up short in two WTA Finals title matches, in 2022 and again last year against Rybakina. Andreeva, who won Indian Wells in 2025, has looked every bit as comfortable in the desert.

Kalshi Indian Wells value picks
The biggest obstacle between Aryna Sabalenka and her first WTA Finals trophy just went home sick.
Elena Rybakina beat Sabalenka in the Australian Open final this year and again in last year’s WTA Finals championship match, so she’s the one player Sabalenka has had real trouble getting past when a title is on the line. With Rybakina out, Sabalenka is the highest-ranked player left in the field, and I’m surprised the market only has her around 36 cents. That works out to roughly +178, which is a fair price for the player with the best hard-court résumé in the draw.
The venue helps too. Sabalenka owns these courts this season. She won the BNP Paribas Open back in March, saving a championship point in a third-set tiebreak against Rybakina, then flew to Miami and finished off the Sunshine Double. She won 23 of her first 24 matches in 2026 and is 47-11 overall. The back half of her year hasn’t matched that start, but the version of Sabalenka that tore through the spring hard-court swing is the one that tends to show up in the desert.
Monday’s win over Karolina Muchova wasn’t pretty. She hit seven double faults, landed only 59% of her first serves and had to break back twice in the opening set. I’d still take it as a positive. Muchova was the one player in Group 2 with a winning head-to-head record against her, and Sabalenka found a way through in straight sets while dealing with sun and shade on her toss.
Mirra Andreeva on Wednesday is the real test. The teenager beat Sabalenka in the 2025 Indian Wells final on this same court, and she looked sharp in Monday’s demolition of Elina Svitolina. That said, Sabalenka holds a 4-2 career edge in that matchup, and she’s 6-1 against Svitolina, her final group opponent. A win Wednesday likely puts her through to the semifinals as the Group 2 winner.
Health is worth keeping an eye on. Sabalenka picked up a knee issue in Wuhan last month, though she gave a positive update before the event, and nothing in Monday’s movement suggested it was bothering her.
Coco Gauff is the name most likely to spoil this, and a potential final against her would be close to a coin flip. Sabalenka got the better of her in the Miami semifinals this spring, though, and I’d rather own the favorite at this number than chase a longer price on someone with a tougher path.

OG.com value picks
This match comes down to one question: can Linda Noskova’s serve hold up against the best returner left in the field? I don’t think it can for three sets.
Noskova will win plenty of free points. She was lights out at Wimbledon and looked crisp again Sunday, wrapping up her first set against Marta Kostyuk in just over half an hour. When she’s landing first serves, she can go toe-to-toe with anyone.
Coco Gauff makes that a lot harder to sustain. She converted 7 of 16 break chances against Jessica Pegula, and that came on a day when her own serve and forehand were shaky. Gauff doesn’t need to be at her best to win these matches. She makes opponents hit one more ball, then one more after that, and over a best-of-three in the desert heat that tends to add up.
The surface works in her favor as well. Gauff is 33-9 on hard courts this season, compared to 21-10 for Noskova, and she’s 2-0 against the Czech on hard courts. Those meetings came back in 2023, before Noskova turned into a Grand Slam champion, so I wouldn’t lean on them too heavily. Their lone 2026 matchup was a coin flip on clay in Madrid, where Noskova survived a third-set tiebreak, and that’s a fair reminder that this won’t be a walkover.
What separates Gauff for me is experience in this exact spot. She’s in her fifth straight WTA Finals, the youngest player to pull that off since Martina Hingis, and she’s already won the whole thing once. Noskova is making her debut, and the round-robin pressure feels different when a semifinal berth is sitting right in front of you.
There’s also a fitness angle that cuts both ways. Gauff spent more than an hour longer on court than Noskova on Sunday, but she’s played sparingly since the U.S. Open, so the legs should be fresh. If anything, a long match against Pegula probably knocked off some rust.
At 61%, the market has Gauff priced around -156, which feels about right for a top-five player against a debutant she’s never lost to on this surface. I’ll back the American to take control of Group 1.

Polymarket value picks
- Coco Gauff vs. Linda Noskova under 22.5 games (50% at Polymarket)
The total sits at 22.5 games, which means a straight-sets match almost always cashes this, and a third set almost always kills it. So the real question is whether either player can put this away in two.
I think there’s a better chance of that than a coin flip suggests, mostly because of how Linda Noskova plays when she’s on. Her service games go quickly, and she doesn’t waste much time in rallies. She won all four of her break points against Marta Kostyuk on Sunday and never lost serve after breaking for 4-2 in the second set. That kind of first-strike tennis doesn’t usually produce marathon sets. It produces breaks and holds that come fast, then a set that swings on one or two return games.
Coco Gauff is the one who can drag matches long, and she did exactly that against Jessica Pegula. That match was a bit of an outlier, though. Gauff was cruising in the third set, and her return game is good enough to turn a single loose service game from Noskova into a 6-3 or 6-4 set. If Gauff gets on top early, I don’t see Noskova grinding back the way Pegula did. If Noskova gets hot on serve, the same logic works in reverse.
The two players were nearly identical behind their first serves in their openers, with Noskova winning 68% of those points and Gauff 67%. That points to a match decided on second serves and return games, which is where breaks pile up and sets end before reaching a tiebreak.
The danger here is obvious enough. Their only meeting this year went the distance in Madrid, and a split-set match would bury this ticket. Still, at even money, I’d rather bet on one player imposing herself in two sets than on another three-hour slog.
