4-bullet brief | narrative

Polymarket puts only 21% on Iran agreeing to end uranium enrichment by June 30, despite Iran releasing deal-framework details.
The 60-day nuclear talks structure disclosed by Iran implies enrichment decisions are deferred beyond June 30, directly consistent with the low 21% probability.
The broader US-Iran nuclear deal by June 30 contract sits at 28%, the gap between 28% and 21% isolates the specific enrichment-halt condition as the harder ask.
Resolves via UMA oracle; Iran must formally agree to cease all uranium enrichment, not merely enter talks, to settle YES by June 30.
