Anthropic’s October 26 S-1 filing for a planned November IPO, targeting a roughly $1.5 trillion valuation, underscores surging demand for its Claude large language models amid heavy infrastructure outlays. Revenue reached $16.3 billion in the first half of 2026, up sharply from prior periods, while the company disclosed over $600 billion in future compute and cloud commitments, largely non-cancelable leases with Amazon, Google, and others. Most of the reported $80.7 billion net loss stemmed from non-cash accounting adjustments tied to convertible notes rather than cash burn, leaving $112 billion in cash reserves. Recent model releases, including Claude Opus 5.5 and Haiku 5.5, highlight ongoing capability gains and competitive positioning against OpenAI and Google. Traders assessing any bankruptcy timeline will watch the IPO launch and Q3 results for signs of sustained revenue scaling versus escalating infrastructure costs.
