Major financial institutions including NYSE, DTCC, and Tradeweb are building blockchain infrastructure for 24/7 trading and instant settlement of tokenized securities.
The New York Stock Exchange, DTCC, and Tradeweb aren’t experimenting with blockchain anymore. They’re building production systems on it.
According to a16z’s Jason Rosenthal, what’s unfolding represents the most significant infrastructure upgrade in capital markets since electronic trading replaced floor traders in the 1990s. DTCC, which processed $3.7 quadrillion in transactions in 2024, received SEC authorization in December 2025 to tokenize real-world assets and is targeting production deployment for U.S. Treasury securities in the first half of 2026.
The Migration Timeline
NYSE announced in January 2026 a platform for 24/7 onchain trading and settlement of U.S. equities and ETFs. The system will support fractional shares, instant settlement, and stablecoin funding, with BNY and Citi backing tokenized deposits across ICE’s clearinghouses.
Tradeweb already executed the first fully onchain financing of U.S. Treasuries against USDC in August 2025—on a Saturday, outside traditional settlement windows. Bank of America, Citadel Securities, DTCC, and Virtu Financial participated. The scope has since expanded to cross-border and intraday settlements.
Nasdaq filed its own proposed rule change with the SEC in September 2025. This week, the Lise stock exchange announced preparations for the first tokenized IPO under the DLT Pilot Regime, adding European momentum to the shift.
The Economic Logic
The current securities infrastructure extracts fees at every layer: broker spreads, prime broker financing, exchange fees, transfer agent fees, custodian charges, and DTCC’s clearing and settlement costs. Even after the U.S. moved to T+1 settlement in 2024, capital remains locked overnight.
Smart contracts and atomic settlement compress that entire stack. Two parties can transact instantly with finality, eliminating the overnight capital lockup that functions as a structural tax on every market participant.
Rosenthal frames the incumbent margin as opportunity: “Their margin is YOUR opportunity to build the new rails.”
What Actually Gets Built
The pattern mirrors the 1990s transition. Exchanges didn’t build E*TRADE or Bloomberg. They didn’t create the order management systems that defined electronic trading. Those came from founders who recognized the infrastructure shift early.
DTCC doesn’t want to build middleware. NYSE doesn’t want to build compliance tooling. Tradeweb doesn’t want to build cross-border distribution layers. These institutions are laying regulated, institutional-grade foundations. The middleware, tooling, and distribution networks represent the building opportunity.
The CLARITY Act, if passed, could provide the regulatory framework that the GENIUS Act established for stablecoins. Combined with existing SEC no-action letters, the regulatory path for tokenized traditional assets is becoming visible.
For traders, the implications are straightforward: 24/7 markets mean continuous price discovery and no more weekend gaps. Instant settlement eliminates counterparty risk windows. Fractional ownership opens previously inaccessible asset classes. The infrastructure buildout is happening now, with production systems targeting 2026 deployment.
