    "Polymarket prices the US-Iran nuclear deal by June 30 at 51%, essentially a coin flip despite deal momentum headlines.",
    "News of a tentative memorandum of understanding is consistent with the near-50% pricing; markets are treating signing and full implementation as genuinely uncertain.",
    "The July 31 deadline contract on Polymarket sits at 59%, showing markets give meaningful extra probability to an 8-week slippage in formalization.",
    "Resolves via UMA oracle; the June 30 contract has only 13 days of runway, a tight window that explains why even positive headlines cannot push probability above 51%."
