4-bullet brief | narrative

Polymarket puts 4% on Iran developing a nuclear weapon before 2027, resolving via UMA oracle.
Trump's stated goal of nuclear prevention and the Camp David national security meeting (Story 11) are consistent with the market's view that weaponization remains unlikely near-term.
The US-Iran framework agreement story (Story 27) and Iran's 'major round of fighting' posture (Story 19) point in opposite directions; the 4% pricing reflects deep uncertainty without resolution.
Companion Kalshi contract on the US reopening its embassy in Iran sits at 4%, suggesting the market prices both war escalation and diplomatic breakthrough as low-probability tail events.
