Remarks from Barack Obama and Donald Trump on the existence of extraterrestrial life have triggered a sharp spike in trading activity on Kalshi and Polymarket, with the combined volume on alien confirmation markets crossing $12m — though the implied probability of an official US confirmation remains well below 25%.
What Obama and Trump Said
In a recent interview, former President Obama stated that he believes aliens are real, while clarifying that he has not seen them. He added there was no vast underground facility dealing with extraterrestrial life, unless a major conspiracy was keeping it hidden.
On February 20, President Trump addressed the subject directly, directing relevant government departments to begin identifying and releasing classified files on the topic.
Based on the tremendous interest shown, I will be directing the Secretary of War, and other relevant Departments and Agencies, to begin the process of identifying and releasing Government files related to alien and extraterrestrial life, UAP, UFOs, and any and all other information connected to these highly complex, but extremely interesting and important, matters.
The statements landed in a prediction market environment already primed for high-volume event trading. Kalshi reported $1bn in Super Bowl trading volume earlier this month, demonstrating the platform’s capacity to absorb large, concentrated bets on major cultural and political events.
Trading Volume Jumps Across Both Platforms
Before the Obama and Trump statements, Kalshi’s “Will the U.S. confirm that aliens exist before 2027?” market had accumulated $1.3m in trading volume. As of February 23, that figure stood at $6.7m — a more than fivefold increase. The current market consensus puts the probability of confirmation at 20%.
Polymarket’s equivalent market shows $5.8m in volume, with traders pricing the event at a 14% likelihood. A narrower Polymarket contract — “Trump declassifies new UFO files by March 31?” — has attracted $16,898 in volume so far, with a 29% implied probability.
The divergence between Kalshi’s 20% and Polymarket’s 14% on broadly similar questions reflects differences in user composition, market structure, and liquidity. Both figures point to meaningful skepticism, even as nominal trading volumes suggest significant speculative interest.
Context: Prediction Markets in an Active Regulatory Moment
The alien markets are an unusual data point in what has otherwise been a fraught few weeks for prediction market operators. Nevada’s Gaming Control Board has sued Coinbase over unlicensed sports event contracts, part of a broader state-level push to assert jurisdiction over platforms that the CFTC oversees at the federal level.
Kalshi itself has been at the centre of that regulatory battle, contesting state gaming regulators’ authority over its federally licensed event contracts. The platform briefly surpassed DraftKings and FanDuel in app downloads ahead of Super Bowl LX, underlining its growing consumer reach even as the legal framework around its operations remains contested.
The alien markets sit outside the sports event contract debate entirely, which may partly explain why they have attracted volume without attracting regulatory friction. Whether Trump’s promised file releases move the probability needle on Kalshi and Polymarket will depend on what those files contain — and whether any disclosure meets the threshold traders have in mind when pricing a “confirmation.”
