Jane Street's AI Blitz Revealed: $6B CoreWeave Compute Commitment, $1B Equity Stake, Anthropic Holding, and Own 200 MW Data Center Plans Behind $16.1B Q1 Trading Revenue

The Wall Street Journal profiled Jane Street's aggressive AI expansion on June 20, revealing the secretive quantitative trading firm committed $6 billion in CoreWeave cloud compute plus a $1 billion equity investment in April 2026, while also holding a stake in Anthropic whose valuation climbed above $800 billion. Jane Street posted $16.1 billion in Q1 2026 trading revenue — more than double year-over-year — with AI-powered strategies credited as a key driver, and the firm plans to hire 500 more staff and self-finance a 100–200 MW data center to scale its AI compute for trading operations. The profile positions Jane Street as one of the largest private-market AI investors outside Big Tech, deploying AI simultaneously as an investment thesis and as an operational edge.
