On January 15, 2026, Coinbase CEO Brian Armstrong announced that the company would no longer back the Senate Banking Committee’s market-structure legislation, citing what he described as regulatory capture by large banks. Speaking on Fox Business’ “Mornings with Maria,” Armstrong said that several late-night amendments — including a reduced role for the CFTC and restrictions on crypto firms’ ability to pay stablecoin holders interest-like rewards — compelled Coinbase to pull its endorsement. His decision, he noted, reflects concerns shared by “much of the industry” about the bill’s provisions, which he argued would deliver a competitive advantage to banks at the expense of digital-asset platforms and their customers.

Just hours after Coinbase’s announcement, Senate Banking Chair Tim Scott formally postponed the scheduled markup and vote, initially set for mid-January, with new dates expected in February or March. Senator Cynthia Lummis, a lead sponsor of similar digital-asset legislation, lamented that Armstrong’s public opposition represented “the 1,000th cut in a death by 1,000 cuts,” but expressed confidence that negotiators could reconvene and address outstanding issues. Key sticking points include stablecoin reward payments — banks warn this could shift up to $1.2 trillion from deposits into digital tokens — and jurisdictional authority between the SEC and CFTC.

Coinbase’s high-profile withdrawal of support sent its shares swinging in both directions on Capitol Hill newsflow, reinforcing the company’s role as a regulatory bellwether. While the precise impact on COIN’s valuation depends on how swiftly lawmakers resolve disagreements, Armstrong highlighted that more than 3,000 banks, led by the American Bankers Association, have petitioned for language that would prohibit crypto exchanges from offering stablecoin interest. With cross-industry talks scheduled to resume over the next several weeks, investors will be closely watching for amendments that restore competitive balance and clarify oversight – developments that could ultimately shape trading volumes on Coinbase’s platform and the growth trajectory of its institutional custody business.
