Karpathy at Anthropic, the Pope at the Vatican, and the Internet Losing Its Mind

· 6 min read

Two things happened in the same week. Both of them involved Anthropic. One was a major hire. The other was a Vatican press conference. Neither was fake. But the internet managed to smash them together into something that was, and now people are asking me if the Pope works at Anthropic.

Let me untangle this.

What actually happened: the Karpathy hire

On May 19, 2026, Andrej Karpathy posted on X: “I’ve joined Anthropic. I think the next few years at the frontier of LLMs will be especially formative. I am very excited to join the team here and get back to R&D.”

This is confirmed. Axios, CNBC, TechCrunch, and VentureBeat all reported it the same day. Anthropic’s own communications confirmed the hire. There is no ambiguity here.

Karpathy joined the pre-training team, reporting to Nick Joseph. His specific role is to help launch a new sub-team focused on using Claude itself to accelerate pre-training research — essentially, using the model to make the next model better. This is the kind of recursive self-improvement loop that sounds like science fiction until you remember that every serious AI lab is already doing it.

For context, Karpathy’s career path reads like a map of the last decade of AI:

  • 2015–2017: Founding member at OpenAI, working as a research scientist.
  • 2017–2022: Director of AI and Autopilot Vision at Tesla, reporting to Elon Musk.
  • February 2023: Returned to OpenAI.
  • February 2024: Left OpenAI again, a year almost to the day.
  • July 2024: Founded Eureka Labs, an AI-native education startup.
  • May 19, 2026: Joined Anthropic, pausing Eureka Labs.

This is a real move, a big one, and it matters. Karpathy is one of the most respected researchers in the field. He co-founded the company that built GPT. And now he is working on Claude. The talent war in AI just got another data point, and it favors Anthropic.

What actually happened: the Pope and the encyclical

On May 25, 2026, Pope Leo XIV personally presented his first encyclical, Magnifica Humanitas, a 42,000-word document on safeguarding human dignity in the age of artificial intelligence. This is the first time a pope has personally presented an encyclical at a press event.

Seated among the cardinals and theologians at the Vatican for the presentation was Christopher Olah, the 33-year-old co-founder of Anthropic. Olah spoke at the event, saying that the Church’s voice is needed to “ensure the gains of AI are shared globally,” since its development is “concentrated in a handful of wealthy nations.”

This is also confirmed. NBC News, CNN, the Washington Post, the National Catholic Reporter, and Vatican News all covered it. Anthropic had been holding events targeting religious leaders across faiths throughout early 2026, including gatherings in March and April where the company invited Christian leaders to its San Francisco headquarters to discuss the spiritual implications of its AI systems.

The Pope did not join Anthropic. Anthropic did not hire the Pope. What happened is that a major AI company’s co-founder stood next to the head of the Catholic Church and said, in public, that the technology industry needs outside voices — including religious ones — to guide it.

You can agree with that or not. But it is not a hiring announcement.

How the rumor was born

The timeline is straightforward:

  1. May 19: Karpathy announces he joined Anthropic. The news is everywhere.
  2. May 19–22: Social media runs with the “X joined Anthropic” joke format. Fake announcements circulate for Kanye West, Johnny Sins, Jack Dorsey, and — inevitably — Pope Leo XIV.
  3. May 25: Pope Leo XIV actually appears alongside Anthropic co-founder Chris Olah at the Vatican. The jokes gain a second life because now there are real photos of Anthropic leadership standing next to the Pope.
  4. May 25: People who missed the first wave of jokes see the Vatican event and sincerely ask whether Anthropic “hired the Pope” or whether Pope Leo is “helping” Anthropic.

The mechanism is familiar. A real event creates a joke template. A second real event makes the joke look plausible to anyone seeing it for the first time without context. Information decays on its way through social media, and now you have people genuinely confused.

Yahoo News ran a fact-check titled “Jack Dorsey Has NOT Joined Anthropic — Trending Joke Is Using Names Of Many Notable People.” That is the level of discourse we are dealing with.

How to verify claims like these

This is the useful part. If you hear that a major figure has joined an AI company, here is how you actually check:

  1. Look for the person’s own statement. Karpathy posted on X. Official personal announcements are the strongest signal. If the Pope posted on his official Vatican account “I have joined Anthropic,” you would have your answer. He did not.
  2. Check major business outlets. Reuters, CNBC, Bloomberg, Axios, TechCrunch. If a major hire happened and none of them covered it within 24 hours, it almost certainly did not happen.
  3. Check the company’s blog and press page. Anthropic’s own communications confirmed Karpathy. They did not announce a papal hire, for obvious reasons.
  4. Check LinkedIn. Not infallible, but senior hires at major companies update their profiles. This catches a surprising number of announcements before they go public.
  5. Be skeptical of screenshots. If the only evidence is a screenshot of a tweet or a meme image, you have nothing. Screenshots are trivially faked. Go find the original post.
  6. Ask whether it passes the common-sense filter. The sitting Pope taking a salaried position at a San Francisco AI startup does not pass the common-sense filter.

What this actually tells us about Anthropic’s week

Strip away the noise and what you have is a company that, in a single week, recruited one of the most accomplished AI researchers on Earth and had its co-founder invited to stand beside the Pope for the first papal encyclical on artificial intelligence.

Whether you care about the talent-war angle or the ethics-and-religion angle, the signal is the same: Anthropic is positioning itself as the AI company that takes alignment and safety seriously enough for both the engineering elite and the Vatican to want to work with it. That is a strategic position, and it is not accidental.

Karpathy chose Anthropic over going back to OpenAI, over staying at Eureka Labs, and over joining any of the other well-funded labs that would have hired him on the spot. Chris Olah chose to sit in the Vatican and endorse the idea that AI development needs guardrails from institutions that think in centuries, not quarterly earnings cycles.

Those are the real stories. They are interesting enough without adding the Pope to the org chart.
