Dinari, a securities token platform, has launched tokenized access to the entire S&P 500 for eligible U.S. investors through a partnership with Circle, the issuer of the USDC stablecoin. The initiative allows users to trade blockchain-based shares funded directly with USDC via self-custody wallets, bypassing traditional brokerage infrastructure.
Each tokenized security—branded as a dShare—is backed one-to-one by an underlying stock held in regulated custody. Investors retain rights such as voting, cash dividends distributed in native USDC, corporate actions, and redemption at market prices. Transactions settle almost instantly on the blockchain, and portfolios can move freely between supported platforms instead of being tied to a single brokerage account.
Fortune reported that the initial rollout supports 724 stock tokens, including all S&P 500 constituents, and is already available across 85 jurisdictions outside the U.S. Dinari’s CEO Gabriel Otte told Fortune that blockchain-based ownership removes many limitations of centralized systems like the Depository Trust and Clearing Corporation, giving investors direct control over their assets.
The launch links the roughly $300 billion stablecoin market with the more than $60 trillion U.S. equities market. Circle declined to comment, citing a quiet period before upcoming earnings. Dinari operates as an SEC-registered transfer agent, and its broker-dealer subsidiary is an SEC-registered FINRA and SIPC member, ensuring compliance with existing securities laws.
The move comes amid growing competition in tokenized equities. Robinhood recently introduced tokenized stock products for European users, while Coinbase and Base are working on similar regulated offerings. A recent a16z crypto report noted that the market value of tokenized stocks surged about 600% to nearly $1.7 billion by mid-2026.
