Pronóstico: Will the U.S. invade Iran before 2027?

Platform comparison

Market context

Polymarket’s contract currently trades at **17% YES**, which puts the market in a minority-tail outcome rather than a base case. On the platform, that price is backed by **USDC** collateral on **Polygon**, with the yes/no outcome settled through **conditional tokens** if the United States commences a military offensive intended to establish control over any part of Iran before the deadline.

The closest historical guide is the 2026 Iran war itself, where the U.S. moved from air and naval strikes into a broader campaign, but Reuters reported in February and March that the Pentagon’s visible posture still pointed more towards sustained air power, missile defence and limited operations than a classic invasion force.[12][9] Reports in March and April also described planning for weeks of ground operations, including raids and possible seizure of coastal or island sites, yet those scenarios were explicitly framed as limited, time-bounded actions rather than a full occupation.[8][11] That distinction matters for this market, because a “Yes” requires an offensive meant to establish control over territory, not merely strikes or temporary raids.

For traders, the main catalysts are any White House or Pentagon shift from pressure tactics to openly territorial language, troop-package changes, or orders tied to ground operations. CNN reported on 3 August that the military was still preparing possible strikes on Iranian sites and that Trump was weighing intensifying the campaign, while the CIA and DIA reportedly judged bombing alone unlikely to change Tehran’s position.[10] If those assessments lead to a decision for escalation, watch for deployment schedules, carrier and airlift movements, and any new targets around the Strait of Hormuz or Iranian nuclear facilities, because those are the clearest operational dependencies before a move from strikes to invasion-like action.[6][10]

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

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.

FAQ

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
