Congress passes Iran war powers resolution by June 30?

Platform comparison

Market context

The real-world event centres on whether both the U.S. House and Senate will pass identical legislation to halt American military action in the recent US/Israel–Iran conflict before 30 June 2026. The House already approved a war powers resolution on 3 June with a 215–208 vote, including four Republicans joining Democrats, though the measure remains symbolic without immediate legal force[1][2]. The Senate previously discharged a similar joint resolution on 19 May, and both chambers now face the procedural step of final passage, which is subject to presidential veto[3][4].

Historically, the War Powers Resolution of 1973, enacted after Vietnam, mandates that hostilities cease within 60 days unless Congress authorises them, yet enforcement often hinges on political will rather than judicial mandate[3]. Comparable cases show that while Congress can direct withdrawal via concurrent resolution, presidents frequently claim emergency exceptions or assert that ceasefires terminate hostilities, as the Trump administration has done regarding Iran[1][2]. The current 100% crowd-implied probability suggests traders view final passage as inevitable, yet the symbolic nature of prior votes and the veto risk frame a cautious reading of that certainty[4].

Traders should monitor the Senate’s upcoming vote schedule, any procedural hurdles, and potential White House statements on the ceasefire’s status, as these could delay or block final passage[4]. Recent reporting confirms the Senate is expected to vote on both resolutions within days or weeks, with the outcome critical to the market’s resolution[4]. For accessibility, German GlüStV implications and US CFTC reach define regulatory boundaries, while ‘no-KYC up to $1,500’ allows UK traders to access this market without identity verification, provided they stay within that threshold, enhancing participation for those seeking direct exposure to this political outcome.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
