Market context
The Trump administration's approach to UFO and unexplained aerial phenomena (UAP) disclosure represents a distinct policy vector from its first term. During 2017–2021, the administration released limited UAP materials under congressional pressure, including the 2020 Navy videos and a preliminary intelligence assessment in 2021. A second Trump presidency, commencing January 2025, operates under different congressional and public expectations: the UAP Disclosure Act framework has matured, the Department of Defense established a formal All-domain Anomaly Resolution Office in 2022, and declassification procedures have evolved. The market's 0% implied probability reflects scepticism that new substantive files—distinct from existing public records—will emerge by June 2026, a 18-month window.
Historical precedent suggests caution. The 1995 CIA acknowledgement of U-2 spy plane misidentifications as UAP sources demonstrated that "new" declassifications often reframe rather than reveal. Trump's first-term declassification orders (executive order 13526 amendments) prioritised counterintelligence and election-related materials; UAP files received secondary attention. Comparable administrations have deferred UAP releases citing national security classification reviews that extend beyond single-term cycles.
Traders monitoring this market should track congressional UAP hearing schedules, Defence Department budget cycle announcements (particularly AARO funding), and executive orders on declassification authority. The Intelligence Authorization Act renewal (typically autumn 2025) may impose new disclosure timelines. Recent reporting from *The Debrief* and congressional testimony indicate pressure for 2025 releases, but administrative machinery for declassification review typically requires 6–12 months post-order.
Methodology
We track Trump declassifies new UFO files by 2026? on the five venues with material liquidity for prediction markets. Live odds come from the Polymarket Polygon order book — the only source that ships real-time data under an open licence. For Kalshi, Betfair and Manifold we list platform attributes (fee, KYC, settlement, payment) instead of fabricated odds, because their APIs use non-comparable contract definitions.
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.
