Polymarket's "US x Iran permanent peace deal by June 15, 2026?" contract sits at 93¢ today, the same date as its resolution deadline, which means traders price this as settled fact rather than forecast, in keeping with the "Stocks surge as US-Iran deal ignites global rally" headline pushing equities into Monday's session. The "S&P 500 (SPX) Up or Down on June 15?" contract at 98¢ is about as close to consensus as a single-day directional bet gets, the Iran deal furnishing the clearest catalyst for a gap-up open. At 24¢, Polymarket's contract on Robert Kenyon winning the 2026 Makerfield by-election makes him a decided underdog, not a coin flip, a distinction worth holding given how often tight British constituency races get called too-close-to-call after the market has already called them. Prediction markets price a 2026 US recession at 16¢ against the NY Fed model's 27¢. That eleven-point gap is hard to square with a yield-curve signal that has historically outlasted single-day equity rallies, however large.

Largest repricings — 72h
Hormuz traffic contracts drifted two points higher across both venues over 72 hours, the Polymarket "returns to normal by end of June" contract moving from 16¢ to 18¢ on $2.3M, with the mechanically equivalent Kalshi PortWatch contract (above-60 transit calls before July 1) tracking the same two-point move on far thinner volume. The pace, peaking above 16 points per hour on the Kalshi side before settling, reads as a brief burst of conviction that then resolved into a slow grind rather than a sustained reassessment, and at 18¢ and 16¢ respectively, neither venue is pricing anything close to an expected normalization.
03
Top volume
Volume followed the sharpest move: the US-Iran permanent peace deal contract on Polymarket absorbed $23.0M in 24 hours while repricing 84 points to 93¢, leaving the Strait of Hormuz contract, up only 13 points on a tenth of the volume, to price what happens next if the deal holds.
04
Divergence — the ledger
Polymarket and Kalshi together put 2026 US recession probability at 16¢. The FRED T10Y3M spread and the New York Fed model jointly imply something closer to 27¢. An eleven-point gap between the rates-derived signal and the crowd-sourced contract is rarely a data lag; it is two camps disagreeing about whether the yield curve still reads the future or merely its own reflection.
05
Politics
Robert Kenyon's chances in the Makerfield by-election sit at 24¢ on Polymarket, down three points in the last day on $164K of volume, a heavy clip for one UK constituency. Nothing in the last 72 hours of headline noise touches Makerfield, which leaves the three-point slide to local information or to the quiet erosion that sentiment undergoes as a vote nears.

Geopolitics
Polymarket's contract on a permanent US-Iran peace deal by June 15 closed Monday at 93¢, up 84 points in a single session on $23M of volume. Deep skepticism became near-consensus in roughly 24 hours. A price that spent most of its life as a long shot now treats the deal as settled fact, and the FT headline on a Hormuz agreement shows traders were not running ahead of the news but catching up to it.

Economics
Polymarket's contract on whether SPX closes up on June 15 settled near consensus at 98¢, up 30 points in 24 hours on $58K of volume. This is less a forecast than a confirmation receipt. The Iran deal headlines and the SpaceX debut gave equity bulls something concrete to price, and by Sunday the uncertainty had largely drained out of the contract.
08
Culture
Kalshi's contract on a GTA6 release by November 30, 2026 sits at 78¢ on $11K of daily volume, unmoved in the last 24 hours, a price that has absorbed Rockstar's continued silence without flinching. The surrounding noise, social media bans, celebrity estate auctions, a musician's death in Brazil, touches none of the release-date math. The market's flatness says traders have already made up their minds.
09
Science & Tech / AI
At 96 cents on Polymarket, the contract on NVIDIA holding the top market-cap position through June 30 is about as settled as a market gets. The $50K of 24-hour volume against a 0.3-point move confirms the price is coasting, not under revision. What gives the number texture is the Anthropic headline. If the Trump administration's freeze on top AI models is a posture rather than a one-off, the competitive assumptions buried in that near-consensus price are doing quiet work.
