Dinari tokenized S&P 500 access has arrived for eligible U.S. investors, with the platform now letting users buy and sell blockchain-based versions of every index constituent through self-custody wallets funded with USDC, bypassing the conventional brokerage stack entirely.
dShares: Custody, Audits, and What You Actually Own
Each tokenized equity, branded as a dShare, is backed one-to-one by the underlying security held in a custodial account at Alpaca Securities LLC, a FINRA-member broker-dealer (CRD# 288202, SEC# 8-69928) segregated from Dinari’s own operating accounts.
That 1:1 backing is verified independently: reserve audits are conducted by a Big 4 accounting firm, and the smart contracts themselves are separately audited. Dinari describes this custodial structure as the model the SEC now references in its own taxonomy of tokenized securities.
Holders retain full economic rights on the underlying stock: voting rights, cash dividends distributed in native USDC, corporate actions, and redemption at market prices. Settlement occurs on-chain, making it near-instant rather than following the standard T+1 or T+2 cycle. Tokenized portfolios can also move between supported platforms without being locked to a single account.
The Circle partnership is central to the stablecoin leg. Dinari frames the launch as a bridge between the roughly $300 billion stablecoin market and the more than $60 trillion U.S. equities market. Circle declined to comment ahead of an upcoming earnings report.
Dinari Tokenized S&P 500 Launch in a Crowded but Still-Nascent Market
The Dinari tokenized S&P 500 rollout lands as the broader tokenized equities sector is accelerating fast. A recent a16z crypto report put the market value of tokenized stocks at nearly $1.7 billion by the end of June, a roughly 600% climb. For context, that is still a rounding error against the $60 trillion underlying market.
Robinhood has launched tokenized stock products for eligible European users on its own blockchain network. Coinbase and Base have signalled they are targeting one-to-one-backed tokenized equities using regulated structures. Securitize and Figure are also active, though Fortune reported their offerings have concentrated on private or specialised assets rather than publicly traded equities.
Dinari’s differentiation is regulatory depth. Reuters reported in June 2025 that Dinari’s broker-dealer subsidiary became the first tokenized equity platform to receive such a registration in the United States, and that the company was working directly with the SEC before going live with its U.S. offering. Dinari had already registered as an SEC transfer agent in 2022. The broker-dealer is also a FINRA and SIPC member.
The platform currently supports 6,139 active tokenized assets across 85 jurisdictions outside the U.S. rollout.
Infrastructure and Institutional Reach
Dinari was founded in 2021 by Gabriel Otte, former LegalZoom executive Chas Rampenthal, and Crunchyroll founder Brandon Ooi. The company raised a $7.5 million seed round in August 2023, backed by Third Kind Venture Capital, SPEILLLP (part of the Susquehanna International Group), 500 Global, Balaji Srinivasan, Sancus Ventures, and Version One VC. A $12.7 million Series A followed, earmarked for expanding tokenized asset offerings and deepening institutional integrations.
The Dinari Financial Network, launched earlier this year, connects broker-dealers, exchanges, custodians, issuers, and transfer agents across the full lifecycle of a tokenized security. In December 2025, Flow Traders partnered with Dinari to provide liquidity for 24/7 trading of dShares across major exchanges, initially covering more than 200 tokenized U.S. equities.
Gemini was the first platform to offer tokenized U.S. stocks in the EU using Dinari’s infrastructure. BitGo provides access to crypto, stablecoins, and tokenized U.S. equities through a Unified API partnership with Dinari.
CEO Gabriel Otte has said he expects blockchain-issued tokens to eventually become the trusted record of stock ownership, displacing the Depository Trust and Clearing Corporation’s role as the central ledger. Whether the SEC’s current receptiveness to Dinari’s model survives future administrations is the variable that the rest of the tokenized equities sector is also betting on.
