Four contracts are seeing real movement this week, and each one has a clear news event behind it. From a Venice premiere to a shakeup atop the 2028 primary field, here's what's driving the numbers right now on Kalshi.
US Open Women's Singles Winner
Aryna Sabalenka is chasing something only Serena Williams has pulled off since 2014: three straight US Open titles. The two-time defending champion still sits atop this market, but her recent form has traders less confident than her ranking alone might suggest: an early Wimbledon exit is still fresh.
Coco Gauff has been closing the gap all tournament. The 2023 champion arrives fresh off a Cincinnati Open title, and her contract has climbed steadily through the opening rounds in New York. A difficult draw stands between her and a potential rematch with Sabalenka, but her current form gives that path real weight.
With the final set for September 12 at Arthur Ashe Stadium, there's still plenty of tennis left to move this number in either direction. And contracts like this one tend to swing hardest in the days right before a final, once the draw clears and the picture sharpens.
Oscar Winner: Best Actor
Matt Damon still tops this board. His turn as Odysseus in Christopher Nolan's The Odyssey has carried him to the front of the field for months, backed by strong reviews and a box office run that's kept the film in the conversation.
The real story this week is John Malkovich, who jumped into second place.
His new film Wild Horse Nine premiered Thursday at the Venice Film Festival, and the reaction has been enthusiastic. Martin McDonagh wrote and directed it, the same filmmaker behind In Bruges, Three Billboards Outside Ebbing, Missouri and The Banshees of Inisherin, two films that turned into major awards contenders after their own Venice debuts.
Malkovich plays a CIA officer sent to Easter Island just before the 1973 coup in Chile, and while he's downplaying the early chatter, telling reporters "the nicest thing is that the film gets attention", two prior nominations without a win give the story an obvious pull heading into voting season.
Andrew Scott holds third, tied to the Ian Charleson biopic Elsinore, which opens the BFI London Film Festival in October before a limited US release in November.
With nominations still five months away, a strong fall festival run can reorder this board more than once, and the gap between second and third right now is thin enough that the next wave of reviews could close it before the wider market catches up.
2027 NFL Champion
Week 1 kicks off this week, and the market has already picked a clear favorite.
Los Angeles Rams sit well ahead of the field after an offseason spending spree that included trading for reigning Defensive Player of the Year Myles Garrett, adding cornerback Trent McDuffie, and coaxing three-time DPOY Aaron Donald out of retirement.
Buffalo and Seattle, the reigning champion, are tied for the next spot, with Baltimore close behind them in a crowded second tier. None of the three is within shouting distance of Los Angeles at the moment.
That gap may shrink fast once real games start counting. A slow start for the Rams, or a hot one from Buffalo or Baltimore, could reshape this board before October, and prices move fastest in these first few weeks, well before most casual fans are even paying attention.
2028 Democratic Presidential Nominee
For most of the past year, Gavin Newsom was the clear favorite in this market, at one point trading above 35%. That's no longer the case. The California governor has slid into third place, and the drop has been gradual rather than sudden: no single headline explains it.
Alexandria Ocasio-Cortez has taken over the top spot, part of a climb that's been building since June.
Georgia Sen. Jon Ossoff sits close behind in second, despite repeatedly insisting he isn't interested in the race: traders clearly aren't taking him at his word.
Kamala Harris trails well behind the top three.
Two years is a long runway for a primary market, and the last few months already show how much room these numbers have to move. Whoever announces first, or doesn't, the current order looks anything but settled. Contracts like this one tend to swing hardest in the days right before a final, once the draw clears and the picture sharpens.
