Nasdaq Gets SEC Approval for Blockchain Settlement

The machinery of American capital markets shifted on March 18, 2026. The SEC formally approved Nasdaq’s proposal to allow securities to be traded and settled in tokenized form – a regulatory green light that opens the door to blockchain settlement inside the world’s most scrutinized national market system.

The pilot is initially limited to Russell 1000 stocks and select ETFs tracking the S&P 500 and Nasdaq-100. Contained for now, but the math is not: a full expansion would touch assets representing roughly $61.6 trillion in U.S. market capitalization.

Tokenized shares share the same CUSIP identifiers, trading symbols, prices, and order books as traditional shares. Brokers tag orders with a “tokenization flag” to indicate settlement preference. If either side can’t support it, the system reverts automatically. Settlement stays at T+1 for now, with real-time atomic settlement as the stated long-term goal. Clearing runs through the Depository Trust Company under a three-year SEC no-action letter issued in December 2025.

According to the SEC filling, Nasdaq has partnered with Kraken to distribute tokenized equities globally, and with Boerse Stuttgart’s Seturion for European institutional access. The official launch requires a 30-day notice and is expected before end of Q3 2026. Industry observers have compared the moment to the shift from paper certificates to electronic trading – structural, but dressed up as incremental.

How is it Different From NYSE’s Approach?

Nasdaq is not moving alone, and its approach is not the only one on the table.

The NYSE is building a separate, 24/7 blockchain venue with real-time (T+0) settlement, stablecoin funding via tokenized deposits from BNY and Citi, and independent pricing. It is not an upgrade – it is a parallel system built on different assumptions about where markets are headed. As of this writing, it is still awaiting SEC approval.

The contrast sharpens when you look at the tradeoffs. Nasdaq’s integrated model preserves liquidity and keeps disruption minimal, but limits what tokenization can actually deliver – fractional shares and programmable settlement features are harder to retrofit onto legacy infrastructure. The NYSE’s parallel model risks temporary price discrepancies between venues but allows a clean slate for genuinely new market structure.

Some analysts frame the NYSE’s always-on model as a direct challenge not just to Nasdaq but to platforms like Coinbase and Robinhood – offering 24/7 trading with the regulatory credibility of a centuries-old exchange behind it.

The Regulatory Patchwork

The SEC’s approval did not happen in isolation. Three broad regulatory approaches have taken shape globally.

The EU and UK have moved toward comprehensive frameworks. MiCA, fully in force as of 2025, created a single licensing passport across 27 member states. The UK’s Digital Securities Sandbox, launched in late 2024, lets institutions including HSBC and NatWest trade tokenized government bonds under modified rules designed to test instant settlement.

Singapore, the UAE, and Hong Kong have taken a test-and-learn approach. Singapore’s Project Guardian – a collaboration between the MAS and banks including JPMorgan and DBS – is building interoperable networks for tokenized funds. Dubai’s VARA has attracted hedge funds tokenizing private equity and real estate, offering regulatory infrastructure most Western jurisdictions lack.

The United States remains the most fragmented. The SEC and CFTC signed a memorandum of understading, to share their roles. Late 2025 Congressional pressure forced the SEC to relax its SAB 121 guidance, finally allowing major banks to custody digital assets without triggering outsized capital charges – clearing a significant barrier to institutional adoption.

The direction across all jurisdictions points toward functional regulation: if a token performs the economic function of a security, it is governed as one, regardless of the technology underneath.

What It Means for Markets

Immediate effects will be modest. Retail investors won’t notice. But the structural math compounds quickly.

The most direct near-term gain is on settlement efficiency. Moving collateral currently takes one to three business days. Atomic settlement – where the asset and cash move simultaneously – could unlock $20 to $30 billion sitting idle in settlement buffers. Eliminating daily bank reconciliation through shared ledger infrastructure could save the industry a further $15 to $20 billion annually by 2027.

Longer term, the BIS is promoting a unified global infrastructure – a “Finternet” – where central bank digital currencies, tokenized deposits, and tokenized assets operate on one programmable layer. Dividend payments, proxy voting, and interest distributions get automated via smart contract, cutting out intermediary chains entirely.

The efficiency gains are real. So is the new risk category. Smart contract bugs in systems governing large asset pools don’t produce slow-moving failures. They move at the speed of code, potentially leaving regulators minutes – not days – to respond.

The Nasdaq pilot is a controlled experiment. But it arrives as every major exchange, central bank, and regulator is working through the same questions. The on-chain era for traditional finance is no longer a prediction. It has a launch date.
