The prediction market on a U.S. confirmation that aliens exist is doing a bumper trade as the government continues to release files.
The Pentagon has released three sets of its own ‘X-Files’ in 2026, filled with supposed witness statements and grainy videos. However, despite a few teasing comments from Donald Trump, there has been no official confirmation that aliens exist.
That’s where the prediction markets come in, as you can buy and sell contracts on the date of announcement. Go for value plays on ‘Before 2028’ or buy the ‘Yes’ on a short-term big-hitter, such as ‘Before September 2026’ at 3¢.
This is the kind of market that Kalshi excels in, and with $30 million+ in trade volume, there’s huge interest. Let’s take a look at some of the big plays and show you how to watch the skies for more developments.
Key Takeaways
- The ‘No’ trades are still the smart play: Yes, the U.S. government has released lots of files, but there’s still no official confirmation that aliens exist. The ‘No’ buys are the way to go.
- Ignore the Pentagon releases: The government has now released three tranches of files, videos, and witness statements on UAPs (Unidentified Anomalous Phenomena). However, data alone does not equal full disclosure on Kalshi’s contract terms.
- Whistleblowers are driving a volatile market: Huge trade volume and big price spikes time with congressional hearings and viral testimony. However, the market won’t resolve without hard evidence and an official thumbsup from the government.

The Truth is Out There: But by Which Date?
🤐 No Confirmation | Before 2027 | 92.5¢
Let's stay on Earth with our heavy trade pick: a big, fat 'No Confirmation'.
Asking the U.S. government to declassify the biggest secret in human history is like asking Marvel to stop making Avengers movies. Theoretically, it’s possible, but don’t hold your breath.
The strict definition of ‘confirmation’ is the driving force in this prediction market. Kalshi’s own terms say that only the President, a Cabinet member, one of the Joint Chiefs of Staff, or a federal agency member must definitively state that aliens exist before January 20, 2029. No one will come out and say it before Trump does.
👽 Yes, Aliens Exist | Confirmed Before January 20, 2029 | 25¢
Both the 'Yes before 2028' and 'Yes before 2029' markets surged 8-9 points in May on the back of the Pentagon releasing declassified videos and photos.
If the genie is out of the bottle on UFOs, a longer buy on ‘Before 2028’ (16%) or the 25% on ‘Before Jan 20, 2029’ are safer options.
Plus, you can always sell if the believers keep the price rising. And with trading volume above $30 million, there are obviously plenty of those keeping the prices afloat.
👽 Yes, Aliens Exist | Confirmed Before 2027 | 7.7¢
The 'Yes, aliens exist before 2027' contract is the ultimate lotto ticket. The argument here relies entirely on momentum.
With the establishment of the All-domain Anomaly Resolution Office (AARO) and high-profile hearings, the ‘disclosure’ train has left the station.
Plus, Matt Gaetz (former U.S. representative for Florida and Trump's initial pick to become Attorney-General) told The Benny Show that he was once briefed on a secret alien breeding program while he was in office.
Believers are banking on a dam-breaking scenario where leaked evidence forces Trump's hand. Not even that can deflect Trump from Iran, the economy, or potentially bad midterms.
Key Actions & Findings 2026
2026 saw a major move forwards in the U.S. confirming the existence of aliens. Well, kind of.
In effect, it was a trickle of information from Donald Trump to whet an alien-obsessed nation’s appetite.
Here’s a brief timeline to understand how and why the Kalshi prediction market on aliens’ existence is so huge.
- February 2026: President Donald Trump posts on his Truth Social platform about “extremely interesting and important matters”, and orders the Secretary of War to begin the process of releasing government files on aliens and Unidentified Aerial Phenomena (UAPs).
- May 8, 2026: The Department of War releases the first tranche of records. The Kalshi ‘Yes Before 2029’ market spikes to 59%.
- May 22, 2026: The second bunch of records is released, featuring over 50 videos and documents. Documented witness reports included claims of seeing “orange orbs swarming”. One video apparently showed a UFO being shot down, but no government confirmation was issued.
- June 12, 2026: The third tranche of witness reports is released. The Pentagon confirms that extra files are to be released on a rolling basis.
- July 2026: The White House appoints polarizing Harvard astronomer, Avi Loeb, to lead a team studying the risks posed by UFOs. Loeb has said that there is a chance that the UFOs/UAPs reported might be extraterrestrial and not man-made, given that astronomers are being hired to investigate.
The key for alien prediction market traders is that despite the witness statements and video evidence, the files don’t draw any definitive conclusions on the existence of extraterrestrials.
Keeping it ambiguous, Donald Trump said on the release:
“With these new Documents and Videos, the people can decide for themselves, 'WHAT THE HELL IS GOING ON?' Have Fun and Enjoy!"
How to Trade on the Confirmation of Aliens’ Existence
Ready to party with little green men? Here’s how to take a position on America coming clean on the existence of extra-terrestrials:
- Prepare to Boldly Go: Visit Kalshi and create an account. You can fund your account with USD and get trading in minutes.
- Navigate Deep Space (or the Kalshi homepage): Search for ‘Will the U.S. confirm that aliens exist?’ under Science and Technology > Space.
- Set Phasers to Stun: Choose whether to buy ‘Yes’ or ‘No’ shares. Set your limit order based on the current bid (e.g. Buy ‘Yes’ at 25¢).
- Monitor the Radio Waves: Your trades are never locked in. You can always monitor prices and sell your shares before the market resolves, potentially locking in profit.
What Would Mulder & Scully Do? UFO Prediction Market Tips
Trading the UFO disclosure prediction markets requires a distinct lack of emotional attachment to E.T. Here are some top tips for trading contracts on whether aliens exist:
- Know when to trade: The volatility has been huge on the prediction market for the U.S. confirming that aliens exist. ‘Yes’ contracts have spiked massively in time with the Secretary of War releasing the latest tranche of documents. The Pentagon has confirmed it will release more papers over time, so keep an eye on the news cycle for more drops.
- Signals to watch: Ignore the grainy TikToks, watch the legislative calendar. Specifically, look for amendments in the annual National Defense Authorization Act (NDAA) related to UAP declassification. If ‘Schumer-Rounds’ style language gets stripped out, hammer the ‘No’. If mandatory declassification passes, the ‘Yes’ becomes a value play.
- How to interpret these probabilities: Trump and others in the administration have been vague about confirming whether aliens exist. So far, it’s been very much a case of ‘make of these what you will’. Remember, the ‘Before Jan 20, 2029’ contracts are still bubbling around the 25% mark. The price is going down as time goes by.
- The value plays aren’t really value: In a binary market, the underdog is the sleeper by default. The U.S. confirming aliens exist outcome represents the biggest potential upset in prediction market history. Its success hinges on a single, world-first event: a mass sighting, a live abduction on daytime TV, or a rogue press conference. The market would be completely shaken if it paid off, turning pennies into dollars overnight.
- The market is enormous: There is a lot of money going in and out of the ‘Will the U.S. confirm that aliens exist?’ market right now ($30 million and counting). That means a lot of trading in and out of positions. Join the wave and try to ignore the desire for millions to get the ultimate confirmation.
‘Do Aliens Exist?’ Prediction Market FAQs
The market's resolution source is strictly for the United States government, meaning a declaration by the UN Secretary General does not automatically trigger a contract payout. While such a major announcement would create immense pressure for the U.S. to follow suit, it does not fulfil the contract's specific requirement for a U.S. federal agency confirmation. Therefore, if the US government remains silent or denies the UN's claim, the ‘No’ trade would theoretically still win.
Prediction market contracts rigorously define ‘government officials’ as individuals currently holding office, so a former president does not qualify as a representative of the Cabinet or a federal agency. His comments are interpreted as personal opinion or civilian speculation rather than an official government disclosure, which explains why the market price remains relatively stagnant. Unless a sitting official explicitly corroborates his claims, the market will not resolve to ‘Yes’ based on his podcast appearance.
Prediction markets typically require an explicit admission that the technology's origin is extraterrestrial, meaning a statement effectively saying ‘we are tracking unidentified objects’ is insufficient for a payout. The government must definitively classify the technology as non-human, rather than simply acknowledging they possess data on aerial phenomena they cannot currently explain. Consequently, they do not need to physically display the craft, but they must verbally confirm its alien nature without ambiguity.
While buying ‘No’ at 97¢ implies a high statistical probability of success, labelling it "free money" dangerously ignores the risk of unexpected whistleblower leaks or sudden policy shifts. Plus, it puts you at a huge risk of losing money if the U.S. government suddenly flips. In volatile political markets, where decisions can be made instantly, it’s better to find value plays further down the trough.
