Anthropic is heading toward one of the largest public listings in history. Shares are expected to trade on Nasdaq under "ANT" around November 19, with an IPO range of $70-$78 for 825 million Class A shares, raising up to $64.4 billion. A concurrent $26 billion private placement from Google, Nvidia, Microsoft, AMD and TSMC could lift total capital raised close to $90 billion. The deal implies about $1 trillion undiluted and up to $1.4 trillion fully diluted, above the $965 billion Series H valuation set in May.
The growth case is strong. Third-quarter revenue reached $17 billion, more than 11 times the prior year, and the annualized run-rate approached $81 billion by late October. More than 11,900 customers now spend at least $100,000 a year, including all of the Fortune 10.
The risks are just as large. Anthropic carries roughly $900 billion in long-term compute commitments. Infrastructure spending consumed about 58% of third-quarter revenue, turning a $974 million profit in the second quarter into a $567 million loss. Market sentiment is fragile after a 6.4% one-day Nasdaq-100 selloff in early November, and post-midterm regulatory uncertainty adds pressure. Governance may also draw criticism: founder-held Class F shares carry 50.1% of the votes, leaving Class A holders little influence.
Comparisons with SpaceX's mid-2026 listing, which raised about $75-86 billion at nearly $1.75 trillion, will shape expectations for a strong debut.
A first-day touch of $1 trillion looks plausible, driven by scarcity and demand for a pure-play AI stock. Sustaining it is harder. Anthropic must show that growth continues beyond the current run-rate and that margins improve through efficiency or custom silicon. If growth slows or compute costs stay high, investors may stop valuing it on revenue multiples and start demanding earnings, and a sharp correction would follow. The IPO is Wall Street's clearest test of whether AI's growth can outrun its capital intensity.
