    "The launch of formal VP-level talks in Switzerland is consistent with above-even pricing, though the market assigns meaningful doubt to any completed deal.",
    "The June 30 short-dated contract at 51% versus 71% by end-2026 captures the market's view that timeline, not deal viability, is the primary uncertainty.",
    "A 19% Polymarket contract on the US invading Iran before 2027 sits alongside the deal contract, framing the outcome distribution as deal-or-escalation, not a stable status quo."
