Prediction markets flipped two leadership races overnight, naming Shabana Mahmood the clear favorite for UK Chancellor and Darline Graham Nordone the frontrunner for South Carolina's GOP Senate nod — both were afterthoughts a week ago.
Two governing bets flipped overnight. UK prediction markets now put Shabana Mahmood at 84% to be the next Chancellor of the Exchequer, up 77 points on the week as Ed Miliband's odds cratered to 5%. In South Carolina, Darline Graham Nordone leapt to 68% for the Republican Senate nomination, up 56 points in a single day, as Russell Fry collapsed to 8% and Ralph Norman slid to 20%. The Gulf told a split story: traders cut the odds of 30 ships transiting the Strait of Hormuz by month's end to just 18%, down 79 points in a week, even as they raised the odds of Iran military action against a Gulf state today to 82%, up 14 points on the day and 74 on the week — a bet on confrontation, not blockade. Elsewhere, Liverpool's exit door swung open: Mohamed Salah's move to Turkey's Süper Lig jumped to 85%, up 80 points in 24 hours.
The Strait of Hormuz thesis is unwinding: traders give just 18% odds that 30 ships transit on any day by July 31, down 13 points on the day and 79 over the week, while 40+ ships sits at 9% (-62 pts/7d) and 50+ at 6% (-20 pts/7d). Yet Iran military action against a Gulf state today is priced at 82%, up 14 on the day and 74 on the week, with strikes for July 19 (74%, +26) and July 22 (52%, +23) also gaining — a bet on confrontation even as the shipping-blockade story fades.
Britain's Treasury bet flipped hard: Shabana Mahmood is now 84% favorite for Chancellor, up 77 points this week, as Ed Miliband collapsed to 5% (-56 pts/7d). South Carolina Republicans handed Darline Graham Nordone a 68% share of the Senate nomination market, up 56 points in a day, at the expense of Russell Fry (8%, -32) and Ralph Norman (20%, -10). The Fed's no-change odds for July held at 95% (+17 pts/7d), while Samuel Alito's retirement-by-2027 odds drifted down to 42% (-14 pts/7d).
NVIDIA and Apple are trading blows for 'largest company' bragging rights: NVIDIA's lead narrowed to 50% (-10 on the day) as Apple climbed to 47% (+10). Apple also gained ground in the December contest, up 9 points to 34%, against NVIDIA's 52%. Databricks' odds of a $165B valuation by July 31 fell to 54% (-16 on the day), while Anthropic's shot at a $1.5T valuation by year-end eased to 68% (-2).
Anthropic's grip on the AI-model markets tightened further: traders now give it 89% odds of having the best model by August, up 18 points in a day, as Moonshot cratered to 4% and Google to 7%. The next Claude Opus release is priced at 91% by July 31 (+12) and 98% by October (+6 pts/7d). SpaceX's Starship Flight Test 13 timeline compressed too, with a July 23 launch now 74% likely, up 44 points on the day.
Mohamed Salah's next stop looks settled: Süper Lig odds jumped to 85%, up a startling 80 points in 24 hours, as Saudi Pro League bets cratered to 12%. LeBron James's market swung toward Miami, now 35% (+18 on the day) over Cleveland's 28% and Golden State's 18%. World Cup markets kept converging on favorites as the final nears — Spain 59%, Messi's Golden Ball 91% — moves better read as the calendar closing in than fresh conviction.
'The Odyssey' opening-weekend box office market swung to 96% odds of topping $115M, up 59 points on the day, as the $105-115M band collapsed to 3% (-55 pts/24h) — a shift that reflects the approaching release-weekend deadline more than new information. A companion market on finer bands now favors $120-125M (32%, +28) and $125-130M (31%, +27), with the sub-$115M outcome down to 2% (-61 pts/24h). Elsewhere, Spider-Man: Brand New Day remains the favorite for 2026's top grosser at 76%, little changed.
Markets are more confident about Britain's next Chancellor than about what happens in the Strait of Hormuz — proof that certainty, like liquidity, pools where the stakes feel smallest.
