Robinhood's shares took a 7.8% hit while Coinbase slipped 6.5% following news that U.S. Congress has postponed crypto market structure legislation. The delay sparked immediate selloff pressure on these two major trading platforms. The postponement suggests a longer timeline ahead for comprehensive crypto regulatory framework in the U.S., leaving market participants uncertain about institutional adoption pathways. Investors appeared to react swiftly to the setback, viewing the delayed legislative action as a near-term headwind for platforms deeply embedded in the American market. The move underscores how closely tied these companies' valuations are to regulatory momentum—any stall in Washington's crypto agenda ripples directly through their stock performance.
