Polymarket traders see 18% chance of US alien disclosure this year

Cumulative trading volume on a related Polymarket contract surpassed $33 million minutes after the U.S. Department of Defense released its first files on Unidentified Aerial Phenomena (UAP). The department published the files last week following a transparency directive from President Donald Trump. In response, traders on the platform are pricing in an 18% probability that the U.S. will officially disclose the existence of extraterrestrial life by the end of the year.
