Anthropic files for IPO: $16.3B in 6 months and 7 founders to hold 50.1% voting control

Anthropic has filed the paperwork for a Nasdaq listing under the ticker ANT, and the filing lands with one very large number attached: $16.3 billion in revenue in the first half of the year through June 30, up from $1.16 billion a year earlier. The company also said second-quarter operating profit reached $974 million on $11.6 billion of revenue. The registration statement does not give a price range, total compute commitments, or third-quarter revenue. It also leaves out official valuation targets, even as reports around the deal have pointed to a mid-November window and ambitions that would put the raise at $100 billion or more.

The governance setup is the other eye-catcher. Anthropic’s seven co-founders will hold 50.1% of the voting power through a single-share structure, giving them majority control over general governance matters. Dario Amodei, Daniela Amodei, Tom Brown, Jack Clark, Jared Kaplan, Sam McCandlish, and Christopher Olah are the people named in the filing. A separate Long Term Benefit Trust holds Class T shares with majority board oversight, while the Anthropic Public Benefit Fund gets 846,840,960 Class N shares, described as 5% of fully diluted shares, with room for more dilution-based grants later.

The financial picture is complicated by paper losses and one-off charges. Anthropic says the first half included $80.7 billion in losses, driven mostly by non-cash markdowns on convertible notes and by stock-related expense tied to earlier Google and Amazon purchases of Series G-2 stock at $259.14 a share, versus Series H pricing at $589.01. On an adjusted basis, net income for the half came to $2.7 billion. The company also says top-line performance for the half reached $4.6 billion, up from $386 million in 2024 and $41 million in 2023.

The filing shows a business that is scaling hard, but not cleanly. More than 11,900 enterprise customers spent at least $100,000 over the trailing twelve months, up from about 950 a year earlier, and net revenue retention was around 900%. No single customer made up more than 10% of revenue in the first nine months of 2026, though the top five together accounted for about 25%. At the same time, Amazon, Google, and Microsoft accounted for 48% of first-half income even while they sell competing models, and Anthropic disclosed huge compute and infrastructure obligations stretching across those same partners and others.
