Will the U.S. invade Iran before 2027?

Platform comparison

Market context

The United States has already been at war with Iran in 2026, but this market is narrower: it pays **Yes** only if Washington starts a fresh offensive intended to establish control over any part of Iranian territory before the end of 2026. At a **22%** crowd-implied probability, the market is pricing this as an **underdog**, with the consensus leaning to **No** unless there is a clear escalation from strikes and naval pressure into a ground-taking mission or occupation-like operation.

Historically, the main comparison set is not a full invasion in the Iraq 2003 sense, but coercive air-and-sea campaigns that stop short of territorial control. Reuters reported in March that Defence Secretary Pete Hegseth said U.S. objectives had not changed and centred on destroying missile launch systems, defence manufacturing and naval forces, while also preventing a nuclear capability[7]. U.S. defence releases likewise described Operation Epic Fury as targeting Iran’s security apparatus and offensive missiles[8][13]. That keeps the current price looking a little rich for a literal invasion, unless traders believe the existing campaign becomes a land-control operation rather than an extended strike-and-blockade campaign.

The catalysts worth watching are any White House, Pentagon or congressional decisions that broaden the mission beyond strikes and maritime coercion. Recent reporting in July said the war had entered a new phase focused on the Strait of Hormuz, including renewed attacks and a naval blockade aimed at shipping access[17]. Reuters also noted discussion of adding thousands of U.S. troops to the theatre, which matters because a sizeable ground deployment would be the clearest sign the market’s definition could be met[7]. The value case for **No** is that the strategic emphasis, for now, is on deterrence, sea lanes and pressure; the contrarian **Yes** case depends on a rapid mission shift, not just more bombing or blockade activity.

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Who Will Win 2026, which mirrors the Polymarket order book directly.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.

FAQ

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 does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

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.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Who Will Win 2026 trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.

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.
