The Securities and Exchange Commission announced on September 17 that it would grant a five-year conditional exemption allowing tokenized U.S. stocks to trade through permissioned automated market makers, a framework designed to test regulated onchain equity markets while preserving investor protections. Under the Innovation Exemption, qualifying venues may operate secondary trading pools for tokenized National Market System stocks provided the tokens convey identical shareholder rights to their traditional counterparts, including dividend entitlement, voting rights and liquidation claims. Primary offerings remain barred from the exemption, and any tokenized stock must still satisfy standard Securities Act registration requirements or qualify under another exemption. The SEC imposed strict caps on participation, limiting Tier One tokenized stocks to 75 symbols and 0.25% of each stock’s prior-month average daily volume, while Tier Two expands the ceiling to 250 symbols and 2.5% volume. Breaching these thresholds triggers a three-month suspension of trading for the affected token. Venues must also publish a public notice at least 30 days before launch and notify the Commission within one business day, with issuers granted a 30-day window to object before trading begins. Smart contracts powering these pools must be auditable and operate on public, permissionless ledgers, though access to the venue itself remains permissioned. Trading must halt immediately if the underlying stock is suspended on its primary exchange. Goldman Sachs and Citizens analysts identified Coinbase, Robinhood and Circle as potential beneficiaries, noting Coinbase’s existing infrastructure for tokenization, custody and stablecoin integration could support compliant onchain equity markets. Coinbase’s international stock tokens are fully backed one-to-one by regulated, bankruptcy-remote shares and already distribute dividends via onchain multipliers, though U.S. availability awaits compliance adjustments. Its Base network has processed over $730 million in decentralized exchange volume in September, with Morpho enabling lending against these tokens using USDC as collateral. Robinhood’s current overseas stock tokens, structured as debt securities without legal claim on underlying companies, do not meet the SEC’s shareholder-rights threshold and would require redesign before U.S. eligibility. The company has signaled plans to add redemption and voting features, but its existing products conflict with the exemption’s requirement for equivalent shareholder rights. Circle could see increased demand for USDC as a settlement asset within qualifying AMM pairs, though the framework does not mandate any specific stablecoin. Traditional market infrastructure providers, including DTCC and major banks, are separately advancing tokenization through DTC-custodied assets, with a limited launch planned for October 2026 following pilot transactions. The SEC frames the exemption as a temporary bridge to inform future rulemaking, emphasizing that synthetic exposure products remain excluded and that price dislocations between AMM pools and conventional markets will be monitored closely.
