A mysterious trader on Polymarket has resurfaced after more than a year of silence, investing $150,000 to predict that the United States will confirm the existence of extraterrestrial life before 2027—despite market odds standing at only 16.8%. The investor's large bet has sparked speculation, but his investment track record is far from flawless: a year ago, he bet on Harris winning the U.S. presidential election on the same platform, ultimately losing $50,000. This shift demonstrates that even seasoned traders on Polymarket struggle to accurately predict highly uncertain events. Can this new investment turn the tide? The market awaits the answer.
