Will the U.S. confirm that aliens exist before 2027?
Prediction markets currently give a 20% probability that Will the U.S. confirm that aliens exist before 2027?. This contract trades at 20¢ on Kalshi, closing January 1, 2027. The Yes side offers an exceptional 562% implied yield with nearly $7M in open interest, but the 20¢ price reflects genuine skepticism about official alien confirmation within 2.3 years—a notably high bar requiring statements from top-tier U.S.
Analysis
The Yes side offers an exceptional 562% implied yield with nearly $7M in open interest, but the 20¢ price reflects genuine skepticism about official alien confirmation within 2.3 years—a notably high bar requiring statements from top-tier U.S. officials. The 2¢ cross-venue gap (Kalshi at 20¢ vs. Polymarket at 18¢) and strong 24-hour volume of $119.5K suggest active arbitrage opportunities, though the low Cliff Risk Index of 4 indicates relatively stable price dynamics despite the asymmetric payoff structure.
Resolution rules
If the President, any member of the Cabinet, any member of the Joint Chiefs of Staff, or any US federal agency definitively states that extraterrestrial life or technology exists before Jan 1, 2027, then the market resolves to Yes.
