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

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.
