Anthropic's rapid revenue acceleration underpins the 92.5% market-implied probability it holds the higher valuation on December 31, 2026. Its annualized run rate reached approximately $65 billion by July 2026 after crossing $47 billion in May, supported by strong enterprise adoption of Claude models and major infrastructure commitments from Amazon and others, following the $965 billion post-money Series H close in late May. OpenAI's run rate stands near $40-41 billion with its most recent primary valuation at $852 billion from the March round. Trader consensus reflects these fundamentals and Anthropic's momentum toward a potential autumn IPO targeting $2 trillion or higher. Key swing factors include the timing and pricing of either company's public debut, any material shifts in quarterly growth rates, or competitive pressures from open-weight models that could compress multiples before year-end.
