Traders Now Bet the Fed Hikes, Not Cuts, in September

Fed-hike odds jumped to 80% on the day the US-Iran ceasefire firmed further and OpenAI's Astra model face-planted on its Arena debut.

Traders spent the day rewriting their Fed playbook: the probability of a 25-basis-point hike after the September meeting jumped to 80%, up 18 points on the day and 29 on the week, dragging the 2026 hike-count market to a dead heat between one and two increases (43% each). In the Middle East, optimism split by geography — the US-Iran ceasefire pause firmed to 86%, up 21 points on the day and 43 on the week, even as traders slashed the odds of an Israel-Lebanon meeting by September 15 to 46%, down a sharp 34 points, while later-date versions of the same market held near 85%. Elsewhere, OpenAI's Astra model cratered on its Arena debut, with markets for a 1480+ score collapsing to just 2%, down 69 points overnight. On the calendar's edge, Alexander Zverev's US Open title odds rose to 58% as Sunday's final approaches.
