Polymarket's "Strait of Hormuz traffic returns to normal by July 31" sits at 51¢, the most conditionally fragile near-consensus in the book: six weeks of resolution window, a contract priced as a coin flip, and any single escalation resets the clock. The same venue prices "Will Anthropic have the best AI model at the end of June 2026?" at 93¢, near-consensus territory with eight days left in the month, a level that leaves a competitor's surprise release almost nowhere to move before resolution. At 12¢ on Polymarket and Kalshi combined against the NY Fed model's 28¢ implied probability, the US recession-in-2026 gap has widened to fifteen points; the crowd is discounting the yield-curve signal more heavily than at any comparable divergence this cycle. Keir Starmer's resignation has no direct Polymarket or Kalshi contract in this week's leaders, which is its own data point. A G7 prime minister departing mid-term generated less addressable volume than a Colombian presidential race priced at 98¢ on Kalshi, where de la Espriella is so close to certain that the contract functions less as a market than a settlement countdown.

Largest repricings — 72h
Fed-no-change at July drifted from 72¢ to 76¢ over 72 hours on $280K, which is a grind rather than a shock, the kind of move that accumulates when traders are revising quietly rather than reacting to a single data point. Against that, the Hormuz contract held at 8¢ through $1.7M of volume, which is the more telling signal: liquidity flowing into a contract that doesn't budge is the market's way of stress-testing a price and finding it settled.
03
Top volume
Starmer at 84¢, up 51 points in a day on $409K, is the single most violent reprice in the set, which makes the Hormuz volume story, $650K in the end-of-June contract at a flat 6¢, the more revealing one.
04
Divergence — the ledger
Polymarket and Kalshi put a US recession in 2026 at a combined 12¢, fifteen points below the 28¢ the FRED T10Y3M spread and the NY Fed model imply. The model-based frameworks are backward-looking by construction, aggregators of credit and rate conditions already on the books. The traders are betting on something those models have not absorbed. Or the contracts are simply lighter on recession signal than the macro data warrants.

Politics
Kalshi's contract on de la Espriella's Colombian presidential victory settled at 98¢ after an 11-point climb on $301K of volume, which is less a price than a ratification: the BBC and Guardian both called the race for the Trump-backed outsider before the market finished adjusting. The lag is the tell. Not that the market was slow, but that 11 points of movement arrived after the headlines had already closed the question, leaving the final two cents as the only honest uncertainty still on the board.

Geopolitics
Polymarket's contract on Hormuz traffic normalizing by July 31 sits at 51¢ after a 9.5-point move in a single session on $343K of volume, which prices a geopolitical chokepoint as a near-coin-flip while the firmest public evidence is two diplomatic statements calling talks encouraging rather than concluded. Progress in US-Iran negotiations and a reopened strait are not the same thing. The market is betting they are close enough.

Economics
Polymarket's July Fed hold contract has slipped four points in twenty-four hours to 74¢ on $323K of volume, just as the Bank of England stayed put and warned, in plain terms, about energy-price drag. The U.S. contract drifts toward doubt while a peer bank vindicates the wait. The price has not yet decided which lesson to take.

Kalshi's Swift-Kelce marriage contract sits at 94¢, a near-consensus read on a couple that has not publicly announced an engagement. That prices the outcome almost as a formality, which is a different claim than "they seem likely to stay together." The contract resolves on marriage specifically, and 94¢ leaves very little room for the ordinary ways that fails to happen by year-end.

Science & Tech / AI
Anthropic's hold on the top-model position prices at 93¢ on Polymarket, down about three points in the last 24 hours on $45K of volume, a small but non-trivial move for a contract that has traded near certainty for weeks. A two-point drift at this level is not noise the same way it would be at 50¢; at 93¢, each point down carries more informational weight, and whoever sold into that price is making a meaningful claim about the next few weeks of model releases.
