Dinari Launches Tokenized S&P 500 Stock Trading for U.S. Investors Through Circle Partnership

Aug 4, 2026

On August 4, 2026, fintech startup Dinari launched tokenized trading of 724 U.S. stocks and ETFs, covering the entire S&P 500, for eligible U.S. investors and businesses. Partnering with Circle, Dinari allows users to trade these blockchain-backed "dShares" directly from self-custody wallets using USDC. The tokens are backed one-for-one by underlying securities in regulated custody, preserving shareholder rights like voting and native USDC dividends. While the tokenized stock market grew 600% to $1.7 billion by June 2026, Dinari warns of potential liquidity and regulatory risks.
