Anthropic's $2 Trillion IPO Could Mint Seven New Tech Billionaires

Anthropic is preparing an initial public offering that could value the San Francisco artificial intelligence company at $2 trillion, according to The New York Times — a debut that would rank as the largest IPO in history. The listing would turn the start-up's seven founders, all of whom left OpenAI in 2021 after disagreements with its executives over how A.I. should be built, into the tech industry's newest billionaires.

The company, best known for its Claude chatbot, was founded by former OpenAI employees who split over safety philosophy. The Times profiled the founders as the IPO preparations advance, and the picture that emerges centers on CEO Dario Amodei — a physicist-turned-A.I. executive who has spent the past year clashing with Washington and Silicon Valley alike.

Who is Dario Amodei?

Dr. Amodei, 43, leads Anthropic as chief executive. Over the past year he has clashed publicly with Defense Secretary Pete Hegseth over the use of A.I. in autonomous lethal weapons and for mass domestic surveillance, The Times reports. He has also been at odds with other tech leaders over a core industry divide: whether A.I. should be openly shared or tightly controlled.

In September, Dr. Amodei published a 3,800-word essay calling for a global slowdown of A.I. development. Weeks later, he had a private dinner with President Trump and attended a luncheon the president hosted with other A.I. leaders.

The sequence is notable: the same executive arguing for restraint on A.I. development is also sitting at the table with the administration weighing how to deploy it. In plain words, Amodei is fighting the industry's biggest battles from both sides of the argument.

What shaped the Anthropic CEO?

Dr. Amodei grew up in San Francisco's Mission District with his younger sister, Daniela Amodei — who is also an Anthropic founder. Their father, who died when Dr. Amodei was in his early 20s, was a leather craftsman. Their mother managed renovation projects for libraries in San Francisco and Berkeley, California. The siblings attended Lowell High School in San Francisco together.

His academic path cuts across the sciences. Dr. Amodei studied physics at the California Institute of Technology, then transferred to Stanford to finish his undergraduate degree. He went on to Princeton for a doctorate in biophysics and computational neuroscience as a Hertz fellow.

After Princeton, he returned to the Bay Area as a postdoctoral researcher at Stanford's School of Medicine. "I was trying to improve diagnostics and curing cancer," he told The New York Times's Ross Douthat in an interview in February.

That medical-research background now sits behind a company that could command a $2 trillion valuation — a figure that would exceed any prior public debut on record.

Why does the founding story matter for the IPO?

Anthropic's origin is a breakaway. The seven founders left OpenAI in 2021 after disagreements with its executives over how A.I. should be built, The Times reports. That schism produced a company whose leadership still frames safety and control as defining questions — even as it prepares for the largest IPO ever attempted.

The tension is the story: the founders who once walked out over how to build A.I. responsibly are now positioned to become billionaires from its commercialization. Watch whether the offering's reception reshapes how investors price that safety-first positioning.
