SpaceX's June 2026 Nasdaq debut at a $1.77 trillion valuation and Anthropic's targeted November listing near $2 trillion anchor trader pricing in this market, with their near-even odds reflecting uncertainty over which will set the year's record. SpaceX's $75 billion raise established the benchmark amid strong initial demand, yet Anthropic's prospectus highlights surging revenue run rates above $65 billion annualized alongside heavy compute outlays that could support a larger debut if execution holds. xAI's February integration into SpaceX removes it as a standalone contender, while delayed timelines for OpenAI and minimal activity from ByteDance, Databricks or others leave little room for disruption. Key swing factors include Anthropic's final roadshow valuation and any last-minute shifts in market conditions ahead of resolution.
