Market context
The Trump administration's approach to unclassified records on extraterrestrial life and unexplained aerial phenomena remains uncertain. During his first term (2017–2021), Trump signed an executive order directing declassification reviews, though limited UFO-related materials emerged publicly, primarily through congressional pressure and Pentagon acknowledgement of the Advanced Aerospace Threat Identification Program. The second Trump administration, commencing January 2025, operates under different institutional constraints and political priorities than the first, with no explicit campaign commitments to UFO file releases documented in mainstream reporting as of late 2024.
Historical precedent suggests declassification of sensitive defence intelligence moves slowly. The 2017 CIA release of previously classified UFO documents came through Freedom of Information Act requests rather than executive initiative. Congressional interest has grown—the 2023 National Defence Authorisation Act included provisions requiring Pentagon reporting on unidentified anomalous phenomena—but executive declassification orders targeting this category specifically have not materialised. The 0% implied probability reflects the absence of scheduled declassification announcements, stated administration priorities in this domain, or legislative deadlines compelling action before June 2026.
Traders should monitor Department of Defence statements, congressional testimony from defence officials, and any executive orders on classification policy. The All-domain Anomaly Resolution Office, established within the Pentagon in 2022, may issue reports that could trigger declassification discussions, though reporting requirements do not mandate public release of classified materials. Media coverage of congressional UFO hearings and administration statements on government transparency will signal shifting likelihood, as will any formal executive directives on intelligence review.

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.
