Pronóstico: US announces withdrawal from Al Udeid Air Base by Sep 30?

Platform comparison

Market context

Polymarket prices this contract at **7% YES**, with traders paying USDC on Polygon for conditional tokens that only settle if there is a public, official US withdrawal announcement for Al Udeid before the deadline.[14] That low price implies the market is treating a full, declared pull-out as a tail event, not merely a temporary repositioning of aircraft or a partial thinning of staff.[14]

Recent reporting matters because Al Udeid has already seen *partial* personnel reductions amid Iran-related tensions, but those moves were described as precautionary rather than an ordered evacuation.[1][3][4] The distinction is important for settlement: the contract requires a declarative announcement of a complete withdrawal of all military personnel, so asset dispersals, temporary redeployments, or unconfirmed satellite imagery would not be enough on their own.[14]

For traders, the main catalysts are any White House, Pentagon, CENTCOM, or embassy-language updates on force posture, plus developments in US-Iran tensions or regional strike risk that could trigger a formal base decision.[1][3][4] Al Udeid is CENTCOM’s forward hub and hosts roughly 10,000 US personnel, so any genuine withdrawal would likely be tied to a larger strategic announcement rather than an isolated base notice.[1][3] Keep an eye on official briefings and scheduled regional defence statements; the market resolves only on a public, authoritative announcement, not on rumours or third-party reporting.[14]

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

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
