Trump declassifies new UFO files by 2026?

Platform comparison

Market context

The Trump administration has already declassified multiple batches of files concerning Unidentified Anomalous Phenomena (UAP) and alleged extraterrestrial life, with the first tranche released on 8 May 2026 under the PURSUE programme. This rolling disclosure process, overseen by the Department of War and including agencies such as NASA and the FBI, has published over 300 documents dating back to the 1940s, including videos of objects being shot down and transcripts from Apollo 17[1][2]. Consequently, the market’s current 0% probability for “new” declassifications by June 2026 reflects the fact that the primary event has already occurred, rendering the conditional outcome effectively impossible under the market’s definition of “not previously publicly available”[2][5].

Historically, similar transparency initiatives—such as the Pentagon’s 2017 disclosure of UFO videos—were followed by incremental releases rather than sudden, large-scale declassifications of previously hidden material[2]. The PURSUE system was explicitly designed as a continuous rollout, with the second and third tranches released on 22 May and 12 June 2026 respectively, confirming that the process is ongoing but not expected to yield entirely new categories of files[2][4]. A power-user evaluating this market programmatically would note that the settlement condition hinges on the release of *previously unavailable* files, a threshold already met by the May releases, making the probability of a future “new” release negligible[2][5].

Traders should monitor the Department of War’s official portal at WAR.GOV/UFO for announcements of further tranches, though these are likely to contain reviewed historical records rather than groundbreaking new material[4][5]. Recent statements from the White House confirm that the administration views the current releases as the beginning of a long-term transparency effort, with no indication of a distinct, separate declassification event scheduled before the settlement date[1][5]. The key dependency is whether the PURSUE programme will release files that were genuinely never before public; given the scale of the May and June releases, this is unlikely to occur, aligning with the market’s 0% implied probability[2][4].
