Robinhood CEO expects all code format verification within 2 years

Robinhood CEO Vlad Tenev said on X that all code will undergo formal verification within two years, starting with safety-critical code and expanding from there, though he gave no company-specific adoption timelines. Tenev co-founded and serves as executive chairman of Harmonic, which builds the Aristotle formal verification tool and said on October 27 that it now supports C and Verilog, extending coverage to software and hardware. The tie matters because a major brokerage CEO is publicly backing formal verification—mathematically proving code meets a specification—as a mainstream engineering standard rather than a niche practice. Watch for concrete adoption milestones from Robinhood and Harmonic customers, and for further expansion of Aristotle's language support beyond C and Verilog.
