By Jake Hari · first written September 1, 2026, before her first-round match. Refreshed after her second-round win; every Kalshi quote on this page is as of 7:17pm ET on September 4, 2026.
Alexandra Eala is two matches into her US Open and has lost eight games doing it: 6-1, 6-2 over qualifier Mary Stoiana on Tuesday night, then 6-1, 6-4 over Oleksandra Oliynykova on Louis Armstrong Stadium on Thursday, a match she opened by winning the first nine points and closed in 64 minutes. That is her first third round at Flushing Meadows, and it comes with a Saturday night assignment: the No. 14 seed Iva Jovic, her close friend and former doubles partner, first match of the night session on Arthur Ashe Stadium at 7pm ET.
Kalshi listed that match at 9:06pm ET on Thursday, and within a day it had become the busiest Saturday match contract the exchange listed. The way it traded is the story of this page told a second time. On September 1, Eala was the most-traded name on the title board at 3 cents bid and 4 cents ask, and this page argued the volume was a crowd, not a view, because almost nothing was bid underneath the price. The match market has now run the same experiment on a one-night clock. Five Eala contracts traded for every Jovic contract, and 93% of the Eala side was bought by people lifting offers. The price opened at 75 cents, fell to 49 by midnight, settled at 48 before dawn, and has not moved off 47 and 48 since.
The difference between September 1 and today is what sits under the price, and that is where this refresh goes first. Every read below is built from Kalshi quotes pulled at 7:17pm ET on September 4; treat them as model estimates, not predictions of fact and not financial advice. Kalshi is a CFTC-regulated exchange and requires traders to be 18+ under its own platform policy; availability varies by state, and whether sports contracts like these count as sports bets a state can regulate is in active litigation after the Ninth Circuit's August 28 ruling.

Two Prices On One Player, Again
Kalshi prices Eala twice this week, the same way it did on September 1. Then it was her first-round match at 79 cents bid, 80 ask, against a 4-cent title contract. Now it is the Jovic match at 47 bid, 48 ask, against a title contract that is still 3 and 4.

The row to read is the first one against the second. Eala's side of the match has traded five times what Jovic's has, and Jovic is the favorite: the 14 seed at 52 to 53 cents, the 17 seed at 47 to 48, a coinflip with a lean. Buyer-heavy flow has spent all day lifting offers on the side the market leans against without moving it a cent.
How The Match Price Got To 48
The first Eala contract in the match market printed at 9:12pm ET on Thursday, six minutes after the listing, at 75 cents. The next three fills went 82, 84, and 85. For the first 40 minutes almost every trade was a buyer paying 70 cents or more for Eala to beat a player who had beaten her twice this year, and the first seller did not show up until 9:49pm, hitting a bid at 57. The 9pm hour closed on a 45-cent print before the 10pm hour opened back at 73, a whipsaw that tells you how thin the first book was.
Then the sellers arrived and did not leave. The 10pm hour averaged 68 cents, the 11pm hour 65, and the midnight hour, the busiest of the night, closed at 49. From 3am on Friday through 4pm, every hour's volume-weighted price rounded to 48 cents. At 6:51pm one buyer swept 11,043 contracts across 48 and 49 cents in 16 same-millisecond fills, the biggest sweep in the market's life, and the quote afterward was 47 bid, 48 ask, exactly where it had been.
Thursday night's first buyers paid 75 to 85 cents. Friday's buyers paid 48. The same crowd that could not move a 4-cent title contract spent a day failing to move a 48-cent match contract.
The reason is the same one the title board showed on September 1, and it lives in the offers. At the 48-cent ask there are about 4,600 contracts, then 30,100 at 49, then 55,500 at 50. That 50-cent stack is the match-market version of the 5-cent wall on the title contract: a price the sellers have decided Eala does not cross before Saturday, backed by enough size that no sweep has pushed through it yet. A buyer who wants Eala at even money can have as much as they like, and the market is telling them the fair number is below it.
What Jovic 2-0 Means When Neither Match Was On Hard Court
The sellers have a record to lean on. Jovic has beaten Eala twice on tour in 2026, both in straight sets, and both in the space of three weeks: 6-4, 6-2 in the first round of the French Open in May, then 6-2, 6-2 in the round of 16 at the HSBC Championships at Queen's Club in June, a match that took 77 minutes. The WTA's own write-up of the second one was titled "Jovic sets friendship aside to defeat Eala again at Queen's," and that is the record the 52-cent Jovic price is quoting.
Here is the case for pricing it closer to even anyway, and it is the case the market seems to have settled on. The French Open is clay. Queen's is grass. Saturday is the first time the two have played a tour match on a hard court, and hard courts are where Eala's season has happened: the Washington title on August 3, where she beat Jessica Pegula in the final, a fourth round in Montreal, a third round in Cincinnati that ended against Amanda Anisimova. Jovic's hard-court summer was shorter. She withdrew from Washington, reached the third round in Montreal as the 13 seed, and lost in Cincinnati's round of 32 to Marie Bouzkova in two tiebreaks, 7-6(0), 7-6(5). Her best hard-court results are real, a WTA title in Guadalajara last year and an Australian Open quarterfinal in January, where she beat Jasmine Paolini and became the youngest American to reach that round in Melbourne since Venus Williams in 1998. They are just not results against Eala.
The one hard-court set the two have played this year was an exhibition, a single set at the US Open's "Stars of the Open" event during Fan Week, and Jovic won it 6-3. It settles nothing and it counts for nothing, which is roughly how the market has treated it.
So the match price is a negotiation between a 2-0 record on the wrong surfaces and a first meeting on the right one, and 52 to 48 is where the negotiation stopped. What it is not is a market that doubts Eala. She has dropped eight games in two rounds; Jovic needed a rain-interrupted 7-5, 6-3 over Magdalena Frech in the first round and a 6-4, 6-4 over Fran Jones in the second. The lean is a record, not a form line.
The Busiest Longshot On The Board Is Still The Busiest
Back to the title board, which is where the September 1 read lives. Here it is re-pulled, sorted the way Kalshi sorts it, by total contracts traded, with the September 1 price beside the current one so the movement is visible.
| Player (Seed) | Kalshi bid / ask, Sept 1 | Kalshi bid / ask, Sept 4 | Lifetime contracts | Open interest | Last 24 hours |
|---|---|---|---|---|---|
| Alexandra Eala (17) | 3¢ / 4¢ | 3¢ / 4¢ | 525,516 | 408,136 | 47,336 |
| Coco Gauff (4) | 18¢ / 19¢ | 16¢ / 17¢ | 493,965 | 363,227 | 47,653 |
| Aryna Sabalenka (1) | 22¢ / 24¢ | 23¢ / 24¢ | 260,581 | 196,121 | 53,059 |
| Elena Rybakina (2) | 4¢ / 5¢ | 6¢ / 7¢ | 212,728 | 144,004 | 19,032 |
| Jessica Pegula (3) | 9¢ / 10¢ | 8¢ / 9¢ | 183,260 | 145,376 | 29,563 |
| Naomi Osaka (13) | 6¢ / 7¢ | 4¢ / 5¢ | 177,873 | 166,910 | 3,531 |

| Iga Swiatek (8) | 15¢ / 16¢ | 13¢ / 14¢ | 143,633 | 108,949 | 11,228 |
Source: Kalshi market KXWTA-26USO, pulled September 4, 2026 at 7:17pm ET. Contracts and open interest are shown in dollars of face value, as above. Karolina Muchova's contract, the fifth-busiest on the board, settled to zero after her third-round loss to Emma Navarro and is omitted.
The first row is the one that has not changed, and that is the point of it. Eala has added about 151,000 contracts since the September 1 pull, 83% of them buyers, and her quote is the same 3 and 4 it has been since August 11. Gauff, the name she was level with on September 1, is now more than 30,000 contracts behind her and two cents cheaper than she was, after a 6-4, 7-6(5) second-round scrap with Paula Badosa. Two rows below make the same point from opposite ends. Rybakina was bid up two cents, 4 to 6, on about 19,000 contracts of 24-hour volume. Osaka drifted down two, 6 to 4, on 3,531 contracts of nobody caring. Eala's 47,336 contracts of caring moved nothing.
Where The Volume Came From: Washington
The first Eala contract on this board traded on August 3, at 10 cents, the same day she beat Pegula in the DC Open final for her first WTA title. Outside a single 20-cent print the next morning it never traded above that opening price again. It was under 5 cents within a week and at 3 to 4 cents by August 11, and it has not left that band since.
What the tape since September 1 adds is a number nobody else has: the buyers are thinning out. Buyers were 79% of the title volume on September 1, 98% on September 2, the day after she beat Stoiana, 82% on September 3, and 67% on September 4, the day before the biggest match of her career. The volume held between roughly 30,000 and 48,000 contracts a day the whole time. The conviction behind it did not.
Four days of buying never pushed through the 5-cent wall, and the share of the tape that was buying fell from 98% to 67% doing it.
The cleanest comparison still sits one row down. Gauff won Cincinnati on August 23 and her volume did what Eala's did after Washington, but her quote went from 14 cents that weekend to 18 and 19 by September 1, and a hard match on Thursday took two of those cents back. Prices that were bid up can be bid down. Eala's was never bid up.
The Liquidity Tell, Three Days Later: 185 Became 41,000
On September 1 this section had one number in it. The best Eala bid, at 3 cents, had about 185 contracts behind it, on a contract that had traded 374,091. That was the tell: a market with almost no real demand at its own price, where a small position sold into the bid would print at 2 cents almost immediately.
That number is gone. The 3-cent bid now carries about 41,200 contracts. The offer side has only grown, roughly 29,000 at 4 cents and 47,000 at 5, up from about 39,000 at 5 on September 1, so the ceiling has not moved in price and has gotten deeper, but the floor has moved. September 1 said a first-round win should lift this contract to about 5 cents on the math alone. Two wins didn't. What changed is the thing that page called the tell: the bid. For scale, Sabalenka has about 450 contracts bid at 23 cents and Gauff about 4,800 at 16, so in contracts the cheapest of the three busiest names now has the deepest bid at its quoted price, though a cent lower Sabalenka's 23,175 at 22 cents is about four times the dollars.
The honest reading of that is narrower than it sounds. A 3-cent bid with 41,000 contracts behind it is about $1,200 of real money, and some of it may be the same buyer base from the volume column, now willing to hold a position rather than just open one. It is not sharp money arguing the price up. But it is the one thing the September 1 book did not have, and the round-trip cost on this contract, the subject of our Kalshi bid-ask spread guide, has stopped being the textbook case. You can get out at 3 now. Three days ago you could not.
The match market shows the same thing at a bigger scale. At the 47-cent bid there are about 4,400 contracts, then 28,900 at 46 and 37,500 at 45. Both sides of that book are deep, which looks like structured liquidity rather than one-sided crowd buying. The crowd is only on one side of it.
The Draw Path A 4-Cent Price Is Quoting
A 4-cent title contract is a price on the whole ladder at once, and the first rung of it is now a coinflip. On the math alone, a 48-cent chance of beating Jovic inside a 4-cent title price means the market values Eala at roughly 8 cents to win the tournament if she wins Saturday night. That is the number I keep coming back to, because two wins have not moved the price a cent. The first-round match was priced at 79 and 80 cents, and the market did not reprice her for winning it. Oliynykova is the better form line: she beat Eala in three sets at Strasbourg in May, and Thursday took 64 minutes. The market did not reprice her for that either. It is waiting on Jovic. Here is the ladder as it stands after two rounds, with each name's Kalshi title price beside it.
| Round | Opponent | Kalshi title price (Sept 4) |
|---|---|---|
| First Round | Mary Stoiana (qualifier), won 6-1, 6-2 | settled |
| Second Round | Oleksandra Oliynykova, won 6-1, 6-4 | settled |
| Third Round | Iva Jovic (14), Saturday 7pm ET, Arthur Ashe | 1¢ / 2¢ (match: Jovic 52¢ / 53¢) |
| Fourth Round | Coco Gauff (4) or Cristina Bucsa | Gauff 16¢ / 17¢; Bucsa 0¢ / 1¢ (match: Bucsa 5¢ / 6¢) |
| Quarterfinal | Mirra Andreeva (5) or Madison Keys (22) side | Andreeva 4¢ / 5¢; Keys 1¢ / 2¢ |
| Semifinal | Iga Swiatek (8) or Elena Rybakina (2) side | Swiatek 13¢ / 14¢; Rybakina 6¢ / 7¢ |
| Final | Aryna Sabalenka (1) or Jessica Pegula (3) side | Sabalenka 23¢ / 24¢; Pegula 8¢ / 9¢ |
Kalshi's match markets quote Bucsa at 5 to 6 cents to beat Gauff, so the fourth round is Gauff for practical purposes. Andreeva beat Eva Lys 6-0, 6-2 and Keys saved five match points against Anna Bondar to reach the third round.
The row that matters is still the fourth one. The market has Gauff at about 94 cents to be waiting on Monday, and her title contract, even after the Badosa scare, is more than four times Eala's. But the third row decides whether the fourth row ever matters, and it is the only rung on this ladder where Eala's opponent is priced as a coinflip. Her company at 3 and 4 cents has thinned too: Rybakina, a cent above her on September 1, has left for 6 and 7, while Anisimova, the player who beat her in Cincinnati, and Marta Kostyuk are still there, and 11 of the board's 21 live rows are bid below 3 cents. The practical read is that Eala's title contract is not a cheap longshot yet. The market is refusing to pay for the wins it expected and is using Jovic as the first real repricing gate.

What Saturday Night Has To Change
On September 1 this page said a first-round win should lift the title price to about 5 cents, and called the 185-contract bid the tell. Two wins later the price is where it was and the bid is 41,000 contracts, so the tell moved and the price did not, and the question has moved with the draw. Saturday's question is narrower: whether the crowd that could not push a 48-cent contract through the 50-cent wall on Friday gets to find out what the contract is worth without it.
The falsifiable version is the 5-cent stack. There are about 47,000 contracts offered there tonight. If Eala wins, the ladder math says her title contract should trade toward 8 cents, and the tell is what that stack does in the first hour after the match: pulled, and the sellers who capped her for a month have changed their minds; hit and consumed, and the crowd bought its way through them, which is what Gauff's crowd did after Cincinnati and what Eala's has not done yet. If the stack is still sitting there at 5 cents on Sunday morning with a 4-cent last trade, nothing about this page has changed. If Jovic wins, the contract settles to zero and 408,000 contracts of open interest, most of it bought between 3 and 5 cents, go with it. Either way, the price that would not move for a month finally has a reason to.
