Market context

This market will resolve to "Yes" if the Islamic Republic of Iran’s current ruling regime is overthrown, collapsed, or otherwise ceases to govern by May 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to “No”. This requires a broad consensus of reporting indicating that core structures of the Islamic Republic (e.g. the office of the Supreme Leader, the Guardian Council, IRGC control under clerical authority) have been dissolved, incapacitated, or replaced by a fundamentally different

Methodology

We read Will the Iranian regime fall by May 31? from four platform perspectives: Polymarket (on-chain CLOB), Kalshi (CFTC-regulated exchange), Betfair Exchange (sports book exchange), Smarkets (peer-to-peer betting exchange). Polymarket's live quote comes directly from the Polygon order book; the other three are listed with their platform attributes — fees, KYC, settlement currency, payment options — because a 1:1 contract comparison without API access would be guesswork.

Resolution & payout

Settlement is the biggest difference between the four platforms: Polymarket on-chain in USDC (instant), Kalshi USD via CFTC (T+1), Betfair and Smarkets in local currency via bank withdrawal (T+1 to T+3). PolyGram routes every trade directly into Polymarket's on-chain settlement, which is why payouts land fastest.
