Anthropic Files for Nasdaq IPO, Disclosing $110 Billion Cloud Deal With Amazon

AI developer Anthropic has officially filed an S-1 prospectus for a Nasdaq IPO under ticker ANT, targeting a valuation between $965 billion and $2.0 trillion. Disclosures revealed major strategic ties with early backer Amazon, including $110 billion in non-cancelable cloud compute commitments with Amazon Web Services through 2036. Anthropic generated $16.3 billion in first-half 2026 revenue but recorded an $80.7 billion net loss, mostly from non-cash accounting adjustments on derivative liabilities tied to stakes held by Amazon and Alphabet. The filing lifted tech shares, with Amazon stock gaining about 1% as investors await its quarterly earnings report.
