Peter Thiel Lectured on the Antichrist at the Vatican's Doorstep. His Company Is Helping Run the Iran War.

A short walk from St. Peter's Square, in a rented room the Vatican pretends doesn't exist, one of Silicon Valley's most powerful men spent four days this month lecturing on the end of the world.

Peter Thiel — co-founder of PayPal, co-founder of Palantir, early bankroller of JD Vance's political career — chose Rome for an invitation-only series on the Antichrist. Not as metaphor. As theology, philosophy, and what he sees as urgent technological prophecy.

While he lectured, his company was helping run an actual war.

The Hottest Ticket in Rome

The four lectures ran from March 8 to 11. The guest list was gold-plated and unpublished. The subject: Biblical apocalypse explored through Rene Girard, Carl Schmitt, Francis Bacon, Jonathan Swift, and John Henry Newman.

Thiel's thesis, developed across multiple lectures and essays over the past year, goes roughly like this: the Antichrist won't look evil. He'll look like a savior. He'll rise to power by warning about existential threats — climate change, AI, nuclear war — and use that fear to accumulate authority. Technology is both the mechanism of apocalypse and the thing that blinds us to it.

"Christians debated these prophecies for millennia," he wrote in the Catholic magazine First Things last November. "Who was the Antichrist? When would he arrive? What would he preach?"

The Catholic establishment wanted no part of it.

Every Institution Ran

The lectures were initially linked to the Pontifical St. Thomas Aquinas University — the Angelicum, best known today as the place where Pope Leo XIV wrote his doctoral thesis. The prospect of a tech billionaire delivering secret Antichrist lectures at the sitting Pope's alma mater proved too much.

"We would like to clarify that this event is not organized by the University, will not take place at the Angelicum, and is not part of any of our institutional initiatives," the university said in a rush statement.

The Catholic University of America in Washington also backed away. Their Cluny Institute — a new initiative bringing together academia, religion, and technology — had been listed as a co-organizer. CUA's response: the Cluny Project is "an independent initiative incubated at the university." Translation: not us.

Only the Vincenzo Gioberti Cultural Association, an Italian group dedicated to "the renewal of Italian political culture," stood by the event. They framed it as defending "the great tradition of classical and Christian thought."

Italian politicians demanded answers. The Italian media consumed the story with equal parts outrage and fascination. Rome loves a spectacle, especially one the Church wants buried.

The Part Nobody's Connecting

Here's what makes this more than a curiosity piece about a rich man's theological hobby.

Palantir, the company Thiel co-founded, holds a $10 billion contract with the U.S. Army. Its Maven Smart System supplies AI-powered weapons targeting for the Iran war. When the conflict launched on February 28, Palantir's stock jumped 15% in a single week. War is good business.

Palantir's partnership with Israel's Ministry of Defense — the one currently supplying AI tools for operations in both Gaza and Iran — traces back to introductions facilitated by Jeffrey Epstein, according to DOJ-released documents reported by Jacobin. Epstein arranged at least six meetings between Thiel and former Israeli prime minister Ehud Barak.

So while Thiel stood in Rome warning that the Antichrist would use technology and fear to accumulate power, his own company was using AI to choose military targets in a war that's killed thousands.

Meanwhile, another AI company — Anthropic — was being blacklisted by the Pentagon for refusing to allow its technology to be used for autonomous weapons. The Trump administration labeled Anthropic a "supply chain risk." Anthropic sued. Palantir's stock kept climbing.

What Thiel Understands That Most People Don't

Strip away the controversy and Thiel's core argument is worth sitting with. He draws on Girard's concept of mimetic desire — the idea that humans don't want things independently but copy each other's wants. This creates cycles of rivalry and violence that societies manage through scapegoating.

Thiel applies this to technology. AI doesn't just automate tasks. It automates desire, rivalry, and the mechanisms of control. The Antichrist, in his reading, isn't a red-horned demon. It's a system that looks like salvation.

The contradiction is that Thiel sees this clearly and profits from it simultaneously. Palantir is the infrastructure of surveillance states. Its tools track migrants for the Trump administration's deportation crackdown. Its AI identifies bombing targets in the Middle East. Its founder lectures on apocalypse in the shadow of the Vatican.

The Perception Gap

This story is mostly circulating in American and European media as a culture-war oddity — a quirky billionaire and his weird theological fixation. Italian outlets treat it as a sovereignty question: why is an American tech baron staging controversial events at Catholic institutions?

What's missing from both framings is the material connection. A man who builds the tools of modern warfare is also the world's most prominent lay theologian of apocalypse. He warns about exactly the kind of power his company exercises.

That gap between what Thiel preaches and what Palantir practices is the story. Not the lectures themselves. Not the outraged universities. The gap.

And it tells you something about this moment in history that nobody in Rome — not the Church, not the media, not the politicians — is asking the obvious question: if you're genuinely worried about technology enabling apocalyptic power, why did you build the company that sells it?
