US-Iran Final Nuclear Deal by…?

Market context

The United States and Iran have signed an initial pact to end their recent war, mandating Tehran to reduce its highly enriched uranium stockpile while suspending key sanctions and reopening the Strait of Hormuz. This agreement, finalized by President Trump on 14 June 2026, establishes a 60-day window for negotiations toward a permanent cessation of hostilities and a final resolution on nuclear matters, though the US retains the option to resume military action if compliance falters[1][2].

Historically, such interim frameworks rarely culminate in binding final treaties without significant external pressure; the 2015 deal, for instance, lifted only selective sanctions in exchange for strict enrichment limits, whereas this current pact promises broader relief tied to future progress[1]. The current crowd-implied probability of 1% reflects this scepticism, mirroring how platforms like Kalshi and Betfair often price low-odds political outcomes differently from Polymarket’s decimal odds, with Kalshi’s KYC requirements and fee structures further diverging from the more accessible, lower-cost Smarkets model on this specific geopolitical event[3].

Traders must monitor the scheduled Geneva signing on 19 June and any subsequent announcements regarding the release of frozen assets, which Vice President Vance has stated will not be automatic but contingent on Iranian compliance[2]. Recent reports indicate that Hezbollah attacks in Lebanon and Israeli military actions could derail these talks, as peace negotiations were already postponed following an overnight attack on 19 June[8]. The next critical dependency is the technical negotiation on uranium stockpiles over the coming months, with the settlement window closing in August 2026[4].

Methodology

This page compares US-Iran Final Nuclear Deal by…? specifically across Polymarket, Kalshi, Betfair Exchange and Smarkets. Live odds come from the Polymarket order book; the other venues' contract details are maintained manually because their APIs aren't directly comparable. Every CTA routes to Polymarket Alternative, which mirrors the Polymarket order book at 0% fees.

Resolution & payout

Polymarket settles via UMA Optimistic Oracle on Polygon. A proposer posts the outcome with a bond, the two-hour window runs, then the smart contract pays USDC.

Kalshi settles USD through the CFTC-regulated clearinghouse — the cleanest variant, with heavier KYC. Betfair Exchange settles in account currency (GBP/EUR), net of 2-5% commission. Smarkets follows the same model as Betfair with a lower default 2% commission.
