Anthropic’s pending IPO, with an S-1 filing in late October 2026 and a Nasdaq roadshow underway targeting up to $1.4 trillion valuation, drives the 95.6% market-implied odds against acquisition before 2027. The company has secured massive independent funding, including a $65 billion round at $965 billion valuation in May 2026, alongside surging revenue exceeding $17 billion in Q3 and strategic compute partnerships with Google, Nvidia, and Broadcom. Founder-controlled governance via a 50.1% voting bloc further supports its standalone path. While regulatory delays to the listing or an unforeseen bid could theoretically intervene in the narrow remaining window, trader consensus views these as low-probability given the advanced IPO momentum and demonstrated scale in large language model development.
