It’s the biggest mystery on the planet—is there intelligent life outside of Earth?
Prediction markets are currently saying that a U.S. government confirmation of aliens by 2027 is possible but still unlikely, even after Trump’s latest disclosure push.
President Trump has said he will order U.S. agencies, including the Pentagon, to identify and release classified files related to UFOs, unidentified aerial phenomena, and possible extraterrestrial life. He specifically framed this as a transparency move after Barack Obama jokingly said on a podcast that aliens are “real” before clarifying there was no evidence of contact during his presidency.
On Polymarket, the main market, “Will the US confirm that aliens exist before 2027?” has seen over about $4.8–5.1 million in trading volume, with prices implying roughly a 15–30% chance at different points this week. And on Kalshi, a similar “U.S. confirms aliens before 2027” contract jumped from around 9–17% earlier in the year to the mid‑20s (about 25–26%) after Trump’s directive to release files.
Per Polymarket, as of February 20, there’s a 14% chance the government will confirm the existence of aliens before 2027.
Current odds snapshot
| Platform | Contract (simplified) | Implied chance (latest reporting) | Volume / notes |
|---|---|---|---|
| Polymarket | US confirms aliens exist before 2027 | Market pricing “Yes” in the teens–high 20s %; “No” ≈ 70–85% | >$4.4–5.1M traded. |
| Kalshi | US confirms aliens exist before 2027 | Around mid‑20s % after spike | Contracts nearly tripled from earlier ~9%. |
| Polymarket | Trump admin confirms aliens in first 100 days | “No” trading near 100% | Crowd sees near‑zero chance of very fast proof. |
| Other books | Trump to confirm aliens exist in Feb 2026 | Odds lengthened but with heavy action | Political/novelty books report >$5M across alien‑related bets. |
Markets are reacting to higher odds of disclosure, not to any new hard evidence that aliens exist; after all, the files could still be inconclusive.
Hence, folks think Trump will release files that neither confirm nor deny the existence of aliens.
The key resolution condition is a formal U.S. government confirmation, not a scientific paper or a private discovery by, say, SpaceX, which is why “Yes” remains an underdog even if traders think alien life somewhere in the universe is likely.
So, do aliens exist?
Scientifically, prediction markets are not claiming to know whether life exists elsewhere in the universe; they are pricing a specific event: the U.S. government officially confirming extraterrestrial life by a deadline (2026–2027 in most contracts). Right now, those markets are effectively saying, “Some chance of near‑term U.S. confirmation, but ‘no confirmation by 2027’ is still the strong favorite.”
