Analysis
The Yes position offers an exceptional 644.7% implied yield with only 258 days to expiry, reflecting extreme conviction that official alien confirmation remains highly unlikely at just 18% probability. A notable 2¢ cross-venue gap exists between Polymarket (18¢) and Kalshi (20¢), suggesting potential arbitrage opportunity, though the tight 1¢ spread and substantial $661k open interest indicate reasonable liquidity despite the niche topic. The modest 7-day decline from 19¢ to 18¢ and neutral regime score suggest stable sentiment, though the 5 Cliff Risk Index warrants caution given the binary nature of the resolution criteria.
Resolution rules
This market will resolve to "Yes" if the President of the United States, any member of the Cabinet of the United States, any member of the Joint Chiefs of Staff, or any US federal agency definitively states that extraterrestrial life or technology exists by December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No". The primary resolution source for this market will be official information from the government of the United States, however a consensus of credible reporting will also be used.
