When half the country believes something, it stops being fringe. A new poll from YouGov finds that nearly half of Americans think extraterrestrials have visited Earth, and a growing share believe the government is hiding what it knows. The numbers are not a quirky survey of Reddit users. They reflect a shift in public opinion that has tracked with congressional hearings, military whistleblower testimony, and a steady drip of declassified UAP footage. The question is no longer whether people believe in alien visits. It is what the government should do about it.
TL;DR: A November 2025 YouGov poll of 1,114 U.S. adults found that 47 percent believe aliens have definitely or probably visited Earth at some point. An additional 42 percent say aliens have probably or definitely visited in recent years, while 41 percent say they have not. The poll also found growing distrust in government handling of UAP information, with a majority believing the government is hiding evidence. Sources linked below.
Timeline
September 2024 YouGov conducts an early poll on alien contact expectations. Results show 17 percent of Americans believe contact will happen within 10 years, 32 percent within 50 years, 41 percent within 100 years, and 44 percent within 200 years. The survey establishes a baseline for measuring shifts in public belief.
November 4-9, 2025 YouGov conducts a new online survey of 1,114 U.S. adults. The poll asks about alien visitation beliefs, recent visitation, government transparency, and expectations for future contact. The results are published in December 2025.
December 19, 2025 WIRED publishes analysis of the YouGov poll results, reporting that 47 percent of Americans believe aliens have definitely or probably visited Earth. The data shows a slight increase across all contact expectation timeframes compared to the September 2024 baseline.
January 2026 Additional outlets analyze the poll data, reporting that 42 percent of respondents believe aliens have visited in recent years, while 41 percent say they have not. The results reveal a closely divided public on the question of recent alien visitation.
What the Poll Found
The November 2025 YouGov poll surveyed 1,114 U.S. adults online between November 4 and 9. The margin of error was approximately 3 percent. Key findings include:
Visitation beliefs. 47 percent of respondents said aliens have definitely or probably visited Earth at some point. 41 percent said they probably or definitely have not. The remaining 12 percent were unsure. Compared to earlier polls, the share of believers has increased.
Recent visitation. 42 percent said aliens have probably or definitely visited in recent years. 41 percent said they have not. This is a closely divided result, with the margin of error making the difference between the two groups statistically negligible.
Government trust. A majority of respondents said they believe the government is hiding evidence about UAP or extraterrestrial contact. This finding tracks with polling trends showing declining public trust in government handling of the UAP topic since congressional hearings began in 2023.
Contact expectations. Compared to the September 2024 baseline, expectations for future alien contact increased across all timeframes. More respondents in 2025 believe contact could happen within 10, 50, 100, and 200 years than in 2024.
Fear vs. hope. The poll found that fear of alien contact exceeds hope among respondents. The ratio has shifted slightly compared to previous polls, suggesting that as belief in alien visitation grows, so does anxiety about what it would mean.
Opposing Perspectives
The disclosure case: Polling advocates argue that rising public belief in alien visitation reflects growing awareness of credible UAP evidence, including congressional testimony by military whistleblowers, declassified military footage, and government acknowledgment that UAP are real and frequently detected. The growing belief is not based on tabloid speculation but on the same evidence that prompted congressional hearings and the establishment of AARO. Public opinion is moving toward demanding transparency.
The skepticism case: Critics note that polling about alien visitation reflects cultural attitudes more than evidence assessment. Americans have consistently believed in alien visitation since the 1940s. The numbers have fluctuated with media coverage, not with new evidence. The 47 percent figure is within the range of historical polls on the topic. The government distrust finding, while striking, reflects a broader trend of declining trust in institutions rather than specific UAP-related concerns.
The policy implication: Regardless of what the poll reveals about alien belief, it has direct policy relevance. Congressional representatives who support UAP disclosure legislation cite constituent demand as a primary motivation. If nearly half the country believes the government is hiding UAP evidence, elected officials have political incentive to support transparency measures. The poll data strengthens the case for legislation like the UAP Disclosure Act of 2025.
