Exclusive: Dinari, founded by Stripe and Apple alums, partners with Circle to offer tokenized stocks to U.S. investors

San Mateo-based startup Dinari has announced the expansion of its tokenized stock platform to U.S. investors, enabling the purchase of S&P 500 equities via blockchain. By partnering with Circle, the platform allows users to fund accounts instantly using USDC to acquire dShares, which represent ownership in underlying securities held in regulated custody. This model aims to bypass traditional brokerage limitations by offering instant settlement and self-custody, effectively bridging the $300 billion stablecoin market with the $60 trillion U.S. equities sector. Dinari’s system preserves shareholder rights, including voting and dividend distributions, while facilitating greater portfolio mobility across platforms. The company distinguishes itself from competitors like Securitize and Figure by focusing on broad access to public stocks rather than niche or private assets. With the tokenized stock market growing approximately 600% to $1.7 billion by June, this move signals a significant shift toward decentralized financial infrastructure. Dinari is already operational in 85 jurisdictions, supporting over 6,000 active tokens as it seeks to modernize opaque capital market systems.
