Anthropic's confidential S-1 filing and plans for a Nasdaq IPO, now eyed for mid-to-late November after U.S. midterms, anchor trader expectations around a $2 trillion closing market cap. Explosive revenue growth, with Q2 2026 figures exceeding $11.5 billion and annualized run rate surpassing $65 billion, combined with recent Claude model releases like Opus 5.5, bolster competitive positioning against OpenAI amid surging enterprise demand for large language models. Heavy compute commitments exceeding $500 billion and prior $42 billion losses highlight capital intensity, yet secondary markets already imply valuations near $1.4 trillion. Key swing factors include final pricing after third-quarter results and any anchor investments from partners like Nvidia or hyperscalers.
