4-bullet brief | narrative

Kalshi prices only a 4% chance the United States reopens its embassy in Iran, per the New York Times resolution standard.
Trading volume on this Kalshi contract surged 1,553 times the prior day's level, signaling a sharp spike in attention to the claim.
Despite the volume surge, the 4% price shows the market is not treating diplomatic activity as a credible path to embassy normalization.
Trump's concurrent rejection of Iran's Hormuz proposal, with Polymarket at 21% on Hormuz normalization by year-end, reinforces the low embassy odds.
