Anthropic’s commanding 94.7% market-implied odds reflect its $965 billion post-money valuation from the May 2026 Series H round, the highest confirmed private mark among listed contenders, backed by an $81 billion revenue run-rate and leadership in the Claude large language model family. Traders view this as durable through month-end given the company’s recent infrastructure commitments and competitive edge over other AI labs. OpenAI’s fresh $1.25 trillion private round narrows the gap but remains secondary in current sentiment. The primary risk to the consensus is an accelerated Anthropic IPO closing before November 30, which would remove it from private-company consideration, or a surprise OpenAI funding surge that overtakes the benchmark.
