Anthropic’s confidential S-1 filing on June 1, 2026, followed by active preparations for a September or October listing with major banks, has driven the 87.5% market-implied probability that its IPO will precede OpenAI’s. The company’s $965 billion valuation after its Series H round and strong revenue trajectory in large language models like Claude support a faster path to public markets. In contrast, OpenAI’s later filing and recent signals of leaning toward 2027 reflect internal deliberations and a more complex corporate structure, creating uncertainty around its timeline. Traders view Anthropic’s clearer near-term catalysts as the decisive factor in the current consensus.
