Anthropic has filed an S-1 registration statement with the SEC to list its Class A shares on the Nasdaq under the symbol ANT. The filing reveals the company recorded $14.2 billion in R&D spending for the 12 months ending June 30, 2026.
Why it matters
The filing highlights the extreme capital intensity of modern AI model development, as Anthropic's R&D spend now rivals established pharmaceutical giants like Eli Lilly. This trajectory underscores the massive compute and infrastructure costs required to sustain high-end AI research and deployment.
Anthropic recorded $14.2 billion in R&D spending over the 12 months ending June 30, 2026, including $9.74 billion in the first half of the year. The company reports that at least two-thirds of this total expenditure is allocated to compute, software, and overhead.
The players
Anthropic

Anthropic accounts for its primary innovation costs by bundling infrastructure expenses, including specialized high-performance computing hardware and software, into research and development. In 2025, the firm began reporting these costs within Note 8 of its income statement to better reflect its operational focus. This financial structure supports a workforce of approximately 5,300 employees as of September 30, 2026, while generating $16.3 billion in revenue during the first half of 2026.
