Anthropic’s confidential IPO filing and aggressive November 2026 listing timeline drive the 97.2% market-implied odds against acquisition before 2027. The company recently closed a $65 billion Series H round at a $965 billion valuation, secured $518 billion in largely non-cancelable compute commitments with Amazon, Google, and Broadcom, and structured founder voting control via Class F shares to maintain independence as a public entity. Recent due-diligence walkaways from a potential $6 billion Decart deal further signal focus on scaling Claude large language models and infrastructure rather than a sale. While regulatory scrutiny or an unexpected strategic bid from a hyperscaler could still intervene, the current trajectory of revenue growth, partnerships, and public-market preparation leaves little room for an acquisition in the remaining months of 2026.
