Traders have flipped their Fed bet: a 25-basis-point September hike is now favored at 51%, up from a minority view a week ago. Meanwhile South Carolina Republicans consolidated fast behind one Senate candidate, and Gulf shipping risk collided with its own deadline.
Prediction markets have flipped their view of the Federal Reserve: traders now put September's odds of a 25-basis-point hike at 51%, up 12 points on the day and 28 over the week, overtaking the long-dominant 'no change' view, now down to 43%. The same repricing shows up across the year — 2026 hike odds are favored at 70%, up 10 points on the day — and in South Carolina, where Republican primary voters look to be consolidating fast: Russell Fry's nomination odds vaulted 57 points to 67% in a single day, at the expense of Pamela Evette (down 32) and Ralph Norman (down 20). In the Gulf, markets pricing Iranian action against a neighboring state jumped toward near-certainty as today's deadline arrived, though traders still expect a fresh round of US-Iran talks by August 31, priced at 48%. And in mathematics, two Fields Medal contenders now sit at 96%.
Gulf risk markets converged hard toward certainty as their July 14 and July 15 deadlines arrived — traders priced Iranian action against a neighboring state at 83% and 66% respectively, more calendar than conviction. Longer-dated bets tell a steadier story: Houthi shipping attacks by July 31 rose 25 points to 40%, while odds of a new US-Iran negotiating round by July 31 slid 7 points to 24%, down 48 over the week. The 60-day negotiation window's extension odds sit at 40%, down 5 on the day. Talks, in short, are fading faster than the shooting is starting.
South Carolina Republicans look to be closing ranks: Russell Fry's odds of winning the Senate special primary jumped 57 points to 67% in a single day, as Pamela Evette (down 32, to 5%) and Ralph Norman (down 20, to 16%) faded fast. Mitch McConnell's retirement odds ticked up 8 points to 40%, though that's still 42 points below last week's reading. In Maine, Troy Jackson extended his lead for the Democratic Senate nod, up 7 points to 76%, while Shenna Bellows slipped 11 points to 10%. And traders now favor a September Fed hike, 51% to 43%, for the first time.
The Fed repricing is broad-based: odds of any 2026 hike rose 10 points to 70%, cumulative hike-by-September odds climbed 10 points to 58%, and the 'Other' outcome (anything beyond three straight pauses) now leads the July-October window at 67%, up 16 points. Meanwhile on MetaDAO, the Credible token sale is romping past its targets — odds of raising over $25M jumped 39 points to 93%, and over $30M rose 32 points to 69% — a rare crypto-market show of enthusiasm on a day dominated by rate anxiety.
Mathematics' biggest prize looks headed for a rare double: both John Pardon (96%, up 17 points on the day and 45 over the week) and Yu Deng (96%, up 11 and 27) are now near-locks for the 2026 Fields Medal, at the expense of Jack Thorne (down 21, to 2%) and Vesselin Dimitrov (down 22, to 3%). Separately, Anthropic's grip on 'best AI model' bragging rights looks secure at 96%, with its edge in math-specific benchmarks a touch less commanding at 80%.
LeBron James' next-team odds keep softening — Cleveland's lead slipped 8 points to 40% on the day (down 16 over the week) while Golden State climbed 7 points to 27%. In football, Kylian Mbappé still leads the Golden Boot race at 56% (up 10 over the week) but has ceded ground in the Golden Ball market, down 2 points to 40% as Jude Bellingham rallied 12 points over the week to 18%. Meanwhile, wedding-guest markets for Taylor Swift and Travis Kelce drifted toward near-certainty for Max Martin (88%) and the Haim sisters (90-91%).
Box office forecasters remain split on 'The Odyssey's' opening weekend: the 95-105m bracket gained 14 points to 28% and the 105-115m band rose 14 points over the week to 24%, while the top-heavy >115m case slipped 4 points to 30% — a genuinely undecided market. In the broader 2026 race, Avengers: Doomsday retains a modest lead at 14%, edging out Toy Story 5 (5%) and The Odyssey itself, still at just 2%.
