The clearing house that sits underneath nearly every US stock trade is about to put a blockchain layer on top of it. The Depository Trust & Clearing Corporation, which oversees roughly $114 trillion in securities, plans to launch its tokenization service in October, making Russell 1000 constituents — including Nvidia, Apple and Microsoft — eligible to be represented as blockchain-based tokens for the first time.
The rollout follows a pilot phase that began in July, and DTCC has been building toward this launch for months with input from more than 50 financial industry firms. According to DTCC's own announcement of the service's development, the effort covers a defined set of highly liquid assets: Russell 1000 stocks, exchange-traded funds tracking major indexes, and US Treasury bills, bonds and notes.
Regulatory clearance came first
DTCC isn't moving ahead informally. Its Depository Trust Company subsidiary received a No-Action Letter from the SEC in December 2025 explicitly authorizing a defined tokenization service for DTC participants and their clients, good for three years. That clearance is what let the pilot proceed through the summer without regulatory ambiguity hanging over each trade.
The design intent, according to DTCC, is to preserve the same investor protections, ownership rights and entitlements that come with holding a security in traditional book-entry form — the tokenized version isn't meant to be a separate, lesser-protected instrument, just a different rail for settlement and transfer.
Why the biggest names matter here
Making Nvidia, Apple and Microsoft eligible isn't a symbolic gesture. Those three stocks alone represent trillions in market capitalization and some of the deepest, most liquid trading volume in US equities. Bringing them onto a tokenized rail gives the service instant relevance to institutional desks that might otherwise treat tokenization as a niche experiment for illiquid assets.

Part of a broader institutional push on-chain
DTCC's move lands alongside a wave of similar infrastructure bets from traditional finance this year — asset managers building tokenized credit funds, banks standing up native crypto custody, and exchanges exploring near-continuous trading hours. DeFi protocols have been courting the same institutional money from the other direction, building compliance-ready rails to meet Wall Street halfway. What sets DTCC's service apart is its position in the plumbing: it doesn't compete with any single bank or broker for tokenization business, it sits underneath all of them. If October's launch goes as planned, it could become the default settlement layer other tokenization efforts end up routing through, simply because it's already where the securities live.
