Will the US confirm that aliens exist by 2027?

Platform comparison

Market context

President Donald Trump has ordered the Pentagon and federal agencies to declassify files on extraterrestrial life, yet the All-domain Anomaly Resolution Office (AARO) explicitly states it has found no evidence of alien beings, activities, or technologies[2]. This directive, issued in February 2026 and followed by multiple document releases through the PURSUE system, has consistently framed materials as unresolved cases rather than confirmations[4]. The historical precedent for US government disclosure is clear: previous releases of UFO records, including the first tranche of over 160 files, failed to definitively confirm extraterrestrial existence, with the Pentagon maintaining that the government cannot make a definitive determination on the nature of observed phenomena[4].

Traders should monitor the fourth release of files on 10 July 2026, which included 40 documents from NASA, the CIA, and the Pentagon, for any shift from “unresolved” to “confirmed” language[4]. The critical dependency remains whether Trump or a Cabinet member moves beyond ordering disclosure to issuing a definitive statement that extraterrestrial life exists, a threshold not met by the current “public can draw their own conclusions” stance[4]. With AARO’s latest report reinforcing the absence of evidence and senior astronomers like Seth Shostak noting no compelling proof thus far, the 0% crowd-implied probability aligns with the official record[2][4].
