Peter Thiel did hold a real four-part lecture series in Rome from March 15 to March 18, 2026. The invitation-only talks took place at Palazzo Orsini Taverna, near the Vatican, and addressed the biblical Antichrist, political authority, existential risks and technology, including artificial intelligence. They were not hosted by the Vatican or the Pontifical University of St. Thomas Aquinas (the Angelicum).
The phrase “AI and the Antichrist” describes a connection in Thiel’s wider argument, not a technical AI conference or the confirmed title of every lecture.
What happened in Rome
| Detail | What is documented |
|---|---|
| Dates | Sunday, March 15, through Wednesday, March 18, 2026 |
| Format | Four private lectures, attended by invitation |
| Venue | Palazzo Orsini Taverna in central Rome |
| Speaker | Peter Thiel |
| Central subject | “The Biblical Antichrist,” alongside political, civilizational and technology-related themes |
| Press access | No ordinary press access; recording and note-taking were reportedly restricted |
| Organizing role | The Vincenzo Gioberti Cultural Association was identified as a co-organizer or organizing participant |
Reuters, the Associated Press and The New York Times reported the dates, private format and Rome setting. “Secret” is therefore best understood as closed-door and invitation-only. The event was publicly reported, not evidence of an occult operation.
The Rome series also followed earlier Thiel lectures in San Francisco in 2025 and Paris in January 2026. Le Monde’s account of the Paris talk places the Rome appearance in an ongoing project rather than a one-off announcement.

#1 Best Overall
- If you want to build a better future, you must believe in secrets.
- The great secret of our time is that there are still uncharted frontiers to explore and new inventions to create. In Zero to One, legendary entrepreneur and investor Peter Thiel shows how we can find singular ways to create those new things.
Was it a Vatican or Angelicum event?
No official Vatican sponsorship has been established. The building’s proximity to the Vatican does not establish institutional involvement.
The Angelicum publicly denied organizing the lectures, hosting them on its premises or including them in an institutional initiative. Its statement is available at angelicum.it. Reuters also reported that no meeting between Thiel and Pope Leo XIV appeared on the pope’s official schedule. That does not prove that no informal contact occurred, but there is no documented papal audience in the cited reporting.
It is consequently inaccurate to call the lectures Vatican-hosted, a papal conference or talks at the pope’s university.
Who organized the talks and who attended?
The Vincenzo Gioberti Cultural Association was identified in reporting as involved in organizing the series. That makes the event a privately arranged cultural and political gathering, not a formal Catholic University, Vatican or papal program.

What Thiel means by “the Antichrist”
In the framework attributed to Thiel’s lectures and related remarks, the Antichrist is less a straightforward identification of one living person than a political force or figure. It promises security from existential dangers—such as nuclear war, climate change or AI—and uses that promise to build a coercive, universal political order.
Thiel has connected this interpretation with Christian eschatology, the Book of Daniel, René Girard and other philosophical and historical references. This is Thiel’s interpretation, not a settled position shared across Christianity or Catholic theology. Christian traditions differ substantially in how they understand the Antichrist, end-times imagery and the relationship between political power and salvation.
How AI fits into the argument
AI as an existential-risk example
AI appears as one example of a danger that can generate demands for centralized authority. The argument is that fear of catastrophic technology may make extraordinary political control appear necessary.

Accounts of Thiel’s earlier lectures describe criticism of proposals to restrain or regulate AI. In that rhetoric, some anti-technology or AI-safety positions are cast as part of the danger associated with the Antichrist: a supposedly protective system that becomes authoritarian. The Washington Post reported details from leaked material from those earlier talks.
What the claim does not establish
There is no evidence that Thiel presented a technical theory proving AI will create the Antichrist. The defensible description is narrower: he uses AI, alongside climate change and nuclear war, in a theological and political critique of existential-risk governance. The Associated Press also reported this broader connection at apnews.com.
Why the event drew Catholic and political criticism
Critics objected to several features of the project:
- Christian apocalyptic language was used to frame current political and technology debates.
- Regulation, environmentalism or concern about AI risk could be portrayed as spiritually or politically suspect.
- Warnings about centralized surveillance and totalitarian power sit uneasily beside Thiel’s relationship to Palantir, whose data-analysis software is used by government, defense and intelligence institutions.
- A billionaire with major political and technological influence was presenting a private worldview as a diagnosis of civilization.
Those reactions came from different sources and should not be collapsed into one “Catholic Church” position. The Angelicum issued an institutional denial; individual Catholic writers, advisers and commentators offered theological or political criticism; and some public responses were anti-billionaire, anti-tech or anti-Trump rather than theological. Wired Italia and The Advocate documented parts of that debate.

Thiel’s warnings about a centralized technological order invite scrutiny because of his connection to Palantir. Palantir is more precisely described as a data-analysis and software company whose products are used in government, defense and intelligence contexts, rather than simply as an “AI company.”
That creates a visible tension between criticizing concentrated technological authority and participating in a business ecosystem that supplies tools to powerful state institutions. It is a subject for political and ethical evaluation, not proof by itself of hypocrisy or wrongdoing.
Protests and political repercussions
The Rome event prompted public criticism and protests, including a demonstration using the slogan “Peter Thiel out of Rome.” Media reports also described politicians seeking clarification about the gathering. Those reports do not, without an official parliamentary or government source, establish a formal Italian government investigation or condemnation.
Claims about a Latin Mass, particular attendees or a possible papal audience remain reported or unverified unless supported by a primary source.

What remains unknown
- There is no public, complete transcript of the four Rome lectures.
- The full attendee list has not been independently confirmed.
- Public accounts combine organizer descriptions, attendee reports, observation and material from earlier lectures; they should not be treated as verbatim records of every Rome session.
- No cited source establishes official Vatican sponsorship or an informal Vatican agreement with the organizers.
The accurate takeaway
Peter Thiel’s Rome lectures were real, private and centered on his interpretation of the Antichrist. They occurred near the Vatican but were not an official Vatican or Angelicum event. AI mattered as one example in a broader argument about existential fear, regulation and centralized political power—not as the sole subject, and not as a technical claim that AI will create the Antichrist.
