Will the US confirm that aliens exist by 2027?

Platform comparison

Market context

The United States government has not definitively confirmed the existence of extraterrestrial life, despite President Donald Trump’s recent directive to declassify files on unidentified aerial phenomena. In May 2026, the Pentagon released over 160 documents under the PURSUE system, yet explicitly stated these were unresolved cases with no verifiable evidence of alien technology or beings[3]. NASA Administrator Jared Isaacman echoed this, confirming that while strange aerial sightings exist, no crashed ships or alien bodies have been found[4].

Historically, similar disclosures have failed to shift official consensus. The 2019 Gallup poll showed 68% of Americans believe the government knows more about UFOs than it shares, yet former intelligence official David Grusch’s 2023 allegations of a crash-retrieval program were dismissed by the Pentagon as false[1]. Even with Trump’s renewed push for transparency, experts like Seth Shostak of the SETI Institute maintain there is no compelling evidence for extraterrestrial life[3]. This pattern explains the current 0% crowd-implied probability: past releases generated excitement but no confirmation.

Traders should monitor upcoming file releases hinted by Trump in February 2026, which he described as “very interesting” and potentially revealing[6]. The All-domain Anomaly Resolution Office is collaborating with the White House to unveil previously unseen UAP information, though physicist Kirkpatrick warns expectations should be tempered, as no photographs or interviews with aliens exist[6]. Any definitive statement from the President, Cabinet, Joint Chiefs, or a federal agency before December 31, 2026, would resolve this market to “Yes”; until then, the absence of such confirmation remains the prevailing reality.
