Market context
The Trump administration has already declassified multiple batches of UFO and UAP files, with the first tranche released on 8 May 2026 and a second on 22 May 2026, containing over 380 documents including videos, audio recordings, and witness testimonies dating back to the 1940s[1][2]. Officials described this as the start of a rolling disclosure process, with further materials to be posted as they are reviewed[1]. Despite these releases, no file has confirmed extraterrestrial origin, though the Pentagon noted the public can now access declassified UAP files instantly without clearance[2].
Historically, declassifications on such topics have followed congressional pressure and public disclosure of evidence, as seen with the Pentagon UFO videos that spurred renewed government attention[1]. The current 0% YES probability implies the market believes no *new* extraterrestrial confirmation will emerge, yet the rolling disclosure framework suggests value may lie in contrarian bets on future batches containing unverified but compelling anomalies[1][7]. Consensus sits firmly on “No”, but the underdog angle gains traction if the third batch, released in late May, hints at spinning discs or glowing orbs without definitive proof[8].
Traders should monitor upcoming PURSUE website updates and scheduled Pentagon announcements for the next tranche, particularly any references to spinning discs, glowing orbs, or objects shot down[1][8]. A recent Washington Post report confirmed Trump’s historic directive to release all secret files on aliens and UFOs, reinforcing the administration’s transparency campaign[5]. Watch for Truth Social posts from Trump, which have previously accompanied major releases, and any congressional requests for additional audio or video evidence[1][7]. The settlement window ends 30 June 2026, leaving little time for surprise disclosures, but the rolling process means value could shift if a fourth batch is announced before the deadline[1].
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, 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.

- 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.
- What does Polymarket cost to trade?

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