Summary

Story summary

Jane Street reported $16.1 billion in Q1 2026 trading revenue—the highest ever—and net income of $10.3 billion, more than double the prior year.
The surge came from medium-frequency, automated trading that rode March volatility from the U.S.–Israeli war with Iran and oil-supply worries.
Rising values of stakes in AI firm Anthropic and cloud-infrastructure provider CoreWeave added to gains, while the firm accesses over 200 venues without outside capital.

History

Historical Context

On May 6 2010 the Dow plunged 998.5 points after a $4.1 billion futures sell order and high-frequency traders amplified the swing, prompting a joint SEC-CFTC report that blamed HFT for added volatility. In response, the SEC tested five-minute circuit breakers on all 404 S&P 500 stocks, beginning June 2010 and ending a six-month trial on Dec 10 2010.
