Trump declassifies new UFO files by 2026?

Platform comparison

Market context

The Trump administration has already begun declassifying files on unidentified anomalous phenomena, with the first tranche released on 8 May 2026 and a second on 22 May, followed by a third on 12 June 2026. These documents, dating back to the late 1940s, include military reports, witness interviews, photographs, videos and audio recordings, some describing spinning discs and glowing orbs, with one video allegedly showing a UFO being shot down[1][2][3]. The process is described as rolling, with additional materials posted as they are reviewed[1][4].

Historically, such disclosures have been rare and incremental, often tied to congressional pressure or public disclosure of Pentagon videos, as seen in the initial release of the PURSUE system files[1]. The current 0% implied probability on this market likely reflects that the core event—declassification of previously secret UFO/UAP files—has already occurred, making the market’s “Yes” condition moot for any future date before June 2026. Traders comparing platforms should note that Polymarket uses decimal odds and lower fees with minimal KYC, whereas Kalshi and Betfair require stricter identity verification and report implied probabilities rather than raw odds, which can obscure the fact that the underlying event is already complete[1][2].

Key catalysts to monitor include further PURSUE tranche releases, official statements from the Department of War or Pentagon, and any legislative hearings on UAPs. The Department of War confirmed the third tranche was released on 12 June 2026, with more files expected on a rolling basis[3][4]. Recent coverage by ABC News highlights the Pentagon’s role in posting “never-before-seen” files on a new government website, reinforcing that transparency is ongoing[2]. No new announcement is required for the market to resolve “No”, as the declassification has already happened.
