Anthropic’s IPO Puts Explosive Growth and Founder Control on the Same Ticket
Anthropic’s IPO Puts Explosive Growth and Founder Control on the Same Ticket
Anthropic’s path to Wall Street began quietly in early June, when it filed confidential IPO paperwork—just weeks after OpenAI did the same. But while OpenAI later indicated it did not expect to list until next year, Anthropic moved ahead, turning its proposed debut into what one account called “a referendum on the business of AI.”
On Monday, the company formally filed its S-1 registration statement with the Securities and Exchange Commission, proposing a Nasdaq Global Select Market listing under the ticker ANT. Anthropic said neither the number of shares nor the offering’s price range had been set, underscoring that the prospectus is a starting gun rather than a finished deal.
The filing gave investors a starkly split financial picture. Revenue reached $16.3 billion in the first half of 2026, up from $1.2 billion a year earlier, while operating losses narrowed to $693 million from $2.1 billion. Yet the company reported an $80.7 billion net loss, largely driven by non-cash accounting adjustments related to convertible debt, and warned that it “may not achieve or sustain profitability in the future.”
More favourable readings stress the underlying operating momentum: Anthropic reported $1.6 billion in adjusted profit for the half-year, a 19% adjusted operating margin in the second quarter and $3.9 billion in operating cash flow. But those gains sit beside enormous future compute commitments, customer concentration and reliance on cloud marketplaces run by Amazon, Google and Microsoft—partners that also compete with it.
The IPO also brings Anthropic’s governance bargain into full view. Its seven co-founders, through the Founder LLC, will retain 50.1% of voting power, while the Long-Term Benefit Trust can appoint most directors. The company says that structure protects its public-benefit and AI-safety mission; critics see public shareholders receiving limited practical influence over a company that itself acknowledges advanced AI could pose catastrophic or existential risks.
