Polymarket 48%

4-bullet brief | narrative

Polymarket prices a 48% chance Strait of Hormuz traffic normalizes by December 31, unchanged from near-even pricing amid escalating blockade enforcement.
U.S. firing on a vessel and Iran's 'clear message' that the strait stays shut are consistent with the market's refusal to price a clear resolution.
The near-50% reading means the market is neither pricing a clean diplomatic breakthrough nor a permanent shutdown through year-end.
Resolves via Polymarket's UMA oracle; as previously noted, the standard is likely a return to pre-crisis traffic volumes, not a political announcement alone.
