Alien Disclosure Betting Odds: Is the U.S. About to Say We’re Not Alone?
You can bet on almost anything these days, and yes, that includes aliens.
Not whether they’re out there, exactly. Whether the U.S. government will stand up and say so before 2026 is over.
On Kalshi and Polymarket, two of the biggest prediction markets around, that question has its own price. Polymarket’s alien markets alone have pulled in more than $70 million in trading.
That price has had quite a year. A podcast answer, a presidential post and six batches of government UFO files all had a hand in it.
So, What Are the Odds?
Here’s where the alien disclosure betting odds stood on September 25, 2026:
| Market | Deadline | Chance of Yes |
|---|---|---|
| Kalshi: Will the U.S. confirm that aliens exist? | Before 2027 | 4.5% |
| Polymarket: U.S. alien confirmation | December 31, 2026 | About 4% |
Quick heads-up if you’re in the U.S.: the Polymarket page is look-but-don’t-touch. It says trading is blocked here.
Both numbers sit deep in long-shot territory. Back in February, though, things looked a lot more exciting.
How a Podcast Answer Became a Presidential Order
In February, former President Barack Obama sat down with podcaster Brian Tyler Cohen. During a round of rapid-fire questions, he was asked whether aliens are real.
“They’re real, but I haven’t seen them,” Obama said. He added that they’re not being kept at Area 51, and you can probably guess how fast that clip traveled.
He soon explained on Instagram that he’d been talking odds: the universe is so vast that there’s probably life out there, but he saw no evidence of alien contact while he was president. He finished with one word: “Really!”

Then the sitting president weighed in. On February 19, President Donald Trump told a reporter on Air Force One that Obama “gave classified information” and “made a big mistake.”
Hours later, Trump posted on Truth Social that he’d have the Pentagon and other agencies find and release government files on aliens and UFOs. That night, Kalshi’s price jumped from about 19% to 28%.
That’s the market’s way of saying, “Okay, now we’re listening.”
Everyone wanted to know what was in those files. It took a few months to find out.
Six Batches of Files and One Missing Sentence
The Pentagon began posting the files on May 8 through a program called PURSUE. That’s short for Presidential Unsealing and Reporting System for UAP Encounters, and UAP is the government’s newer word for UFOs.
Five more batches have followed, the latest on September 18. There’s a lot to dig through, from videos and audio to decades-old reports from agencies like the FBI and CIA.
- Read J. Allen Hynek's assessment of the UFO reports he investigated
- Explore the cases and disputes behind Project Blue Book
- Add historical context when comparing modern UAP claims with earlier investigations
The September batch even included 37 old papers on warp drives, wormholes and invisibility cloaking, from a defense intelligence program that wrapped up in 2012. The Pentagon says they shouldn’t be read as a stamp of approval for any of it.
What’s missing is the one sentence the bet needs.
Kalshi’s price was about 25% going into the first release. A week later, it was down to about 15%, and it’s been sliding pretty much ever since.
More files, lower odds.
So why doesn’t a stack of real government UFO files count? Blame the fine print.
The Fine Print: Who Has to Say It
Both sites use nearly the same rule. The president, a Cabinet member, a member of the Joint Chiefs of Staff or a federal agency has to flat-out say that extraterrestrial life or technology exists before the year runs out.
Kalshi even spells out who counts as Cabinet, right down to the head of the Small Business Administration. So in theory, the SBA could settle one of the strangest bets on the internet.
What doesn’t count? According to Kalshi, speculation, anonymous reports and vague nods to unexplained phenomena won’t do it, and it named Obama’s podcast comments as an example.
A blurry video won’t get it done either. Even this bet needs someone willing to put their name to the aliens.

- Explore why compelling stories can feel more convincing than the evidence warrants
- Bring a thoughtful scientific perspective to UFOs, mysteries, and unfamiliar ideas
And if someone ever does? Here’s what a Yes would actually pay.
How a Five-Cent Bet Works
These bets are called event contracts, and the deal is simple. Winning contracts settle at $1, and losing ones settle at $0.
Say you buy a Yes contract for five cents. If the confirmation arrives in time, you get $1 back, a 95-cent gain before fees.
If it doesn’t, your nickel is gone. Cheap to buy, but perfectly capable of losing every cent you put in.
The price also doubles as the crowd’s best guess. Kalshi says prices reflect what traders think the odds are, so five cents works out to roughly a 5% chance.
Here’s the part that surprises people.
You Can Believe in Aliens and Still Bet No
You could be sure there’s life out there and still bet No without blinking. Believing in aliens and betting on Washington are two very different things.
Obama’s Instagram post landed in pretty much the same spot.
No also has a nice track record here. Polymarket already ran shorter versions of this bet, with deadlines at the end of March, April, May and June, and every single one paid the No side.
But the year isn’t over yet.
The Aliens Have Until New Year’s
So is the U.S. about to say we’re not alone? The traders don’t think so, at least not this year.
Still, the Pentagon plans to keep releasing files, and it only takes one official sentence to flip the whole thing.
The universe can take its time. Anyone holding a Yes contract would just like Washington to hurry up.
