Author: Jason Rosenthal, Operating Partner at a16z. Wall Street is no longer merely exploring blockchain—it’s migrating to it. For years, the institutions that form the backbone of global capital markets—exchanges, clearinghouses, and electronic trading platforms—have watched from the sidelines; now, they’re moving on-chain. What’s unfolding today is the largest infrastructure upgrade to capital markets since the rise of electronic trading three decades ago. Yet most people won’t realize this until the transformation is complete.
Why now? Speed changes everything. Every institution moving in this direction shares one conviction: on-chain infrastructure will dramatically accelerate the flow of capital. History has made this clear. Consider the evolution of electronic trading in the 1990s: before electronic communication networks (ECNs) and online brokers emerged, a trade took minutes to execute, spreads were quoted in fractions, and access was constrained by geography and capital requirements. Then the infrastructure changed. Spreads collapsed, commissions dropped from $150 to $9.95—and eventually to zero—trading volume exploded, and retail participation surged. Markets in the 2000s looked nothing like those of the 1990s—not only cheaper, but vastly larger in scale.
Tokenization applies the same logic across the entire global financial system: 24/7 markets, instant settlement, seamless cross-border distribution, fractional ownership of assets previously locked behind six-figure minimums, and collateral that moves in real time instead of sitting idle overnight. Higher trading speed, broader participation, and a bigger market pie. But what does tokenization actually mean? Tokenized assets are digital representations of real-world assets (RWAs)—such as U.S. Treasuries, Apple stock, or real estate deeds—recorded as programmable tokens on a blockchain. Unlike legacy systems where custodians tracked ownership in centralized databases during specific time zones and business hours, tokenized assets exist on-chain: transferable, programmable, and instantly settleable anywhere in the world, at any time. They are not derivatives—they are the real assets themselves, backed by a far more robust underlying architecture.
Institutions have already begun acting. In December 2025, the Depository Trust & Clearing Corporation (DTCC) received a “no-action” letter from the U.S. Securities and Exchange Commission (SEC), authorizing it to tokenize RWAs on an approved blockchain. In 2024, DTCC processed $37 trillion in transactions. Its current goal is to launch tokenized U.S. Treasury services in the first half of 2026. On January 19, 2026, the New York Stock Exchange (NYSE) announced a platform for 24/7 on-chain trading and settlement of U.S. equities and ETFs—including fractional shares, instant settlement, and stablecoin financing—in partnership with BNY Mellon and Citigroup, supporting tokenized deposits at ICE Clear U.S. The world’s most iconic securities exchange is embracing on-chain trading.
Tradeweb completed its first fully on-chain, real-time U.S. Treasury financing transaction denominated in USDC in August 2025—executed on a Saturday, bypassing traditional settlement windows, with participants including Bank of America, Citadel Securities, DTCC, and Virtu Financial. Since then, this financing model has expanded quarterly and now includes cross-border and intraday settlement. Nasdaq submitted its proposed rule change to the SEC in September 2025. This increasingly looks less like a series of isolated experiments—and more like a migration.
A second driver accelerating this shift is the hidden cost embedded in the current system: today’s markets are built around intermediaries, not markets. Consider a typical equity trade: traders pay spreads to brokers. In institutional trading, prime brokers charge financing fees. Exchanges and transfer agents collect commissions. Custodians levy custody fees. DTCC charges for clearing, netting, and settlement. Even after the U.S. finally achieves T+1 settlement in 2024—a reform decades in the making because processing used to take days—funds remain locked up overnight, effectively imposing a “structural tax” on all participants. Smart contracts and atomic settlement break this logjam. Now, counterparties can transact instantly on-chain, with finality guaranteed upon execution. The profit margins—the “spread”—embedded in the existing system haven’t vanished… they’ve become opportunities for new entrants. In other words: their margin is your opportunity to build the next system.
The final breakthrough lies in regulatory clarity—and that process has finally begun. If current momentum continues, the impact of the CLARITY Act on traditional finance will mirror that of the GENIUS Act on stablecoin adoption and acceleration. The guardrails large institutions need are beginning to emerge. So what does this mean for builders? The migration of global financial infrastructure on-chain will generate demand for entirely new categories of products and services. The fastest-moving incumbents aren’t your competitors—they’re your customers. DTCC doesn’t want to build middleware. The NYSE doesn’t want to build compliance tooling. Tradeweb doesn’t want to build the cross-border distribution layer. These firms are building regulated, institutional-grade infrastructure. Founders, meanwhile, build everything that runs on top of it—just as in the 1990s. Exchanges didn’t build E*TRADE. They didn’t build Bloomberg Terminals. They didn’t build the order management systems and prime brokerage platforms that defined the next era. Those were built by founders who saw the future coming. More participants. Faster flows. Less friction. Higher liquidity. Bigger markets. History has made the ultimate trajectory unmistakably clear. The window to build the foundational infrastructure for tokenized financial markets is open. Seize it—and build deliberately.

Wall Street’s Blockchain Migration: The Largest Infrastructure Shift in 30 Years
Market Impact: A Paradigm Shift in Capital Markets
Jason Rosenthal’s article from a16z isn’t just another bullish take on crypto—it’s a stark declaration that the largest infrastructure upgrade in Wall Street since electronic trading is underway. This isn’t about speculative tokens or DeFi experiments; it’s about the migration of $37 trillion in annual transactions processed by the DTCC alone onto blockchain infrastructure.
The implications are profound. For years, we’ve witnessed crypto’s “build it and they will come” approach. Now, the tables have turned. Traditional financial institutions aren’t just dabbling—they’re actively rebuilding their core infrastructure on-chain. The DTCC’s SEC approval for tokenizing RWAs, the NYSE’s partnership with BNY Mellon and Citigroup for 24/7 trading, and Tradeweb’s successful on-chain Treasury transactions aren’t pilots. They’re the first dominoes in what will be a multi-year migration.
This fundamentally alters the crypto market’s trajectory. We’re moving from a crypto-native ecosystem trying to attract TradFi to TradFi actively adopting crypto infrastructure. The distinction between “on-chain” and “off-chain” will increasingly blur as traditional markets rebuild themselves on distributed ledger technology.
Token Price Implications: Beyond the Hype
The market has already begun pricing in this shift, but the real opportunity lies in identifying which segments will capture disproportionate value.
Infrastructure Layer Winners:
– Settlement and clearing tokens: Those enabling atomic settlement and reducing T+1 friction will see significant upside. The “structural tax” Rosenthal mentions represents billions in annual fees that blockchain can eliminate.
– Oracle providers: As RWAs proliferate, reliable price feeds for tokenized stocks, bonds, and real estate become critical.
– Interoperability solutions: With multiple institutions potentially using different blockchains, cross-chain communication protocols will be essential.
Application Layer Opportunities:
– Composable DeFi primitives: Just as the 1990s electronic revolution spawned E*TRADE and Bloomberg Terminals, we’ll see specialized applications built on top of institutional infrastructure.
– RWA-specific platforms: Solutions for fractional ownership of real estate, private credit, and alternative assets will unlock trillions in currently illiquid markets.
I’m particularly bullish on settlement infrastructure tokens. The DTCC alone processes $37 trillion annually—imagine even a small percentage of those fees flowing to blockchain-based settlement solutions. This isn’t speculative; it’s capturing value from existing, high-margin services.
Risks: The Devil in the Details
Despite the optimistic outlook, several risks demand attention:
Regulatory Uncertainty: While Rosenthal rightly notes regulatory guardrails are emerging, the SEC’s approach to crypto remains inconsistent. A sudden shift in regulatory posture could slow institutional adoption, regardless of technological superiority.
Legacy System Integration: The transition will be messy. Legacy systems won’t disappear overnight, creating complex hybrid environments that introduce new points of failure. The first major incident in this hybrid environment could set back adoption significantly.
Centralization Risks: The current trajectory suggests large financial institutions will control the new infrastructure. While technically decentralized, this could result in a “permissioned” blockchain ecosystem that merely replaces old intermediaries with new ones.
Timeline Mismatch: Crypto markets often operate on 12-24 month cycles, while infrastructure transformations take years. We could see a period where crypto prices decouple from the slow-moving institutional reality, creating volatility for investors.
Investment Strategy: Navigating the Transition
For experienced investors, this shift demands a nuanced approach:
Short-term (6-12 months): Focus on infrastructure plays with clear institutional partnerships. Projects like those enabling the NYSE’s 24/7 trading platform or Tradeweb’s Treasury settlements will likely outperform.
Mid-term (1-3 years): Monitor RWA adoption curves. As tokenized Treasuries and equities gain liquidity, platforms facilitating their trading and management will capture value. Watch for specific asset classes crossing the chasm from pilot to production.
Long-term (3+ years): The real opportunity lies in applications we can’t yet fully imagine. Just as few predicted Robinhood or Bloomberg during the early days of electronic trading, the most valuable applications in tokenized markets remain undiscovered.
I’m particularly interested in the intersection of DeFi and TradFi emerging from this shift. We’re likely to see “institutional DeFi” protocols that maintain composability while meeting regulatory requirements—a hybrid approach that could unlock the best of both worlds.
Conclusion: A Structural, Not Cyclical, Shift
This isn’t another crypto bull run—it’s a fundamental restructuring of global financial infrastructure. The institutions driving this change have decades of experience, trillions in assets, and the regulatory relationships necessary to execute this transition.
For crypto investors, the lesson is clear: the narrative is shifting from disruption to infrastructure. The winners won’t necessarily be the projects with the highest TVL or most users, but those solving real problems for institutions migrating trillions in assets on-chain.
The window Rosenthal mentions is open, but it won’t remain so indefinitely. Within the next 18-24 months, we’ll likely see clear winners emerge in the institutional blockchain space. For those paying attention, this represents not just an opportunity for alpha generation, but a chance to participate in what will likely be the most significant financial transformation of our lifetime.
As institutions continue their migration, the crypto market will increasingly reflect real economic activity rather than purely speculative flows. This maturation, while potentially reducing volatility in the short term, will ultimately create a more robust and valuable ecosystem for long-term investors.
