Trump declassifies new UFO files by 2026?

Platform comparison

Market context

The Trump administration has already declassified a substantial collection of files on unidentified anomalous phenomena, with the first tranche released on 8 May 2026 and a third on 12 June 2026, meaning the core event this market hinges on has already occurred [1][3]. In prediction markets, a YES share pays out if the specified outcome happens before the settlement date, while a NO share pays out if it does not; here, the outcome is whether *new*, previously unavailable files on extraterrestrial life or unexplained aerial phenomena are released by 30 June 2026 [1]. Given that the initial release was explicitly described as the start of a rolling disclosure process, the 0% crowd-implied probability likely reflects that the market interprets the question as asking for *brand-new* files beyond what has already been published, not the act of declassification itself [1].

Historically, similar rolling disclosures—such as the Pentagon’s 2026 UFO file releases—have included materials dating back to the 1940s but have not yet confirmed extraterrestrial origins, with officials stating the cases remain unresolved [1][2]. Traders should monitor official announcements from the Department of War (formerly Defence) via PURSUE and WAR.GOV/UFO for any indication of additional tranches containing *never-before-seen* files, particularly those explicitly linked to extraterrestrial hypotheses [3][4]. A recent ABC News report confirms that while the released files include redacted documents, none have led to a conclusion that UAPs are extraterrestrial, suggesting future releases may follow the same pattern unless a breakthrough occurs [2]. Watch for Truth Social posts by President Trump or press releases from the White House Aliens portal, as these have previously accompanied major disclosure milestones [1][10].

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 Prediction Market UK, which mirrors the Polymarket order book directly.

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

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.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Prediction Market UK 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.
