Hey, it’s Marc & the 51 team.
The SEC submitted a proposal outlining how securities laws apply to crypto. This means: SEC won’t wait for Congress. And Washington is betting on private stablecoins and regulated crypto. [SEC] More on that below.
Here are our highlights this week:
ICE (NYSE’s parent) invested in OKX at a $25 billion valuation, with plans to let OKX users trade tokenized NYSE-listed stocks on-chain by H2 2026. [RELEASE]
We sat down with the man responsible for this. Watch our interview here.
Morgan Stanley (AUM: $7T) applied for a crypto broker-dealer license, moving to offer direct BTC, ETH, and SOL trading to its E-Trade users through ZeroHash. [FILLING]
Kraken became the first digital asset bank to receive a Federal Reserve master account. This is historic. [RELEASE]
Five US regional banks (Huntington, First Horizon, M&T, KeyCorp, and Old National) are building “Cari,” a shared tokenized deposit network targeting launch by Q4 2026. [RELEASE]
Stripe is not buying PayPal. PayPal officially denied being in sale talks, and its stock dropped after the denial, reversing the initial 7% pop.
Mastercard processes 160 billion transactions a year. Now it’s letting AI agents spend that money for you. [RELEASE]

Top Signals This Week
ICE (NYSE’s parent) invests in OKX at a $25B valuation
Intercontinental Exchange, NYSE's parent company, has taken a minority stake in OKX, valuing the crypto exchange at $25 billion. ICE invested roughly $200 million, secured a board seat, and licensed OKX's spot crypto prices to launch U.S.-regulated futures contracts. In return, OKX's 120 million users gain access to ICE's futures markets and NYSE tokenized equities, pending regulatory approval. OKB surged over 35% on the news. [RELEASE]
Why this matters: This is ICE's third major crypto infrastructure move in four months — it's buying infrastructure, piece by piece. Polymarket gave it a data layer it can license into derivatives pricing. The BNY and Citi partnership locked in clearing and settlement. OKX adds distribution: 120 million crypto users who will get access to NYSE tokenized equities by H2 2026. The business model is straightforward, licensing OKX's spot crypto prices to launch regulated U.S. futures, the same data-licensing playbook ICE has run for 20 years. It now controls the exchange, the clearing houses, the data pipes, the prediction layer, and the crypto user base.

Kraken receive Federal reserve master account
Kraken Financial, Kraken’s Wyoming-chartered bank, has become the first digital asset company in U.S. history to receive a Federal Reserve master account, granted by the Federal Reserve Bank of Kansas City on March 4, 2026, after a 5.5-year regulatory process. The account is a limited-purpose Tier 3 structure: Kraken must hold 100% reserves, earns no interest on deposits, and has no access to the Fed’s emergency lending window. [RELEASE]
Why this matters: With this approval, Kraken settles directly on the Fed’s balance sheet in real time, no intermediaries, no holds, full U.S. government-backed finality. That closes the last major gap between crypto and traditional finance settlement. BNY Mellon and State Street‘s institutional pitch was built on exclusive Fed rail access, that exclusivity just ended. Timing matters too: this lands right before Kraken’s IPO, and a Fed master account is one of the most powerful things you can put in an S-1.

Morgan Stanley applies for a crypto broker-dealer license
Morgan Stanley has applied for a crypto broker-dealer license with the SEC, moving to offer direct BTC, ETH, and SOL trading to its E-Trade users through ZeroHash as the backend settlement layer. This follows the bank’s earlier OCC filing to create Morgan Stanley Digital Trust, a federally chartered national trust bank focused on crypto custody. [FILLING]
Why this matters: Over the past six months,Morgan Stanley has filed for Bitcoin and Solana ETFs, hired its first Head of Digital Asset Strategy, applied for a crypto trust charter throughMorgan Stanley Digital Trust for custody, and updated its Investment Committee guidance to recommend 2-4% crypto allocations to its 16,000 financial advisors. The broker-dealer license connects it all: custody via the trust charter, trading viaE-Trade andZeroHash, product access via the ETFs, and distribution through the advisory network. These two filings alone, a trust charter for custody and a broker-dealer license for spot trading, gives Morgan Stanley the full client stack in crypto, with E-Trade’s retail base as the distribution engine.

US regional banks launch “Cari” tokenized deposit network
Five U.S. regional banks, Huntington Bancshares, First Horizon, M&T Bank, KeyCorp, and Old National Bancorp have formed a consortium to build Cari Network, a permissioned blockchain platform for tokenized deposits. Led by former U.S. Comptroller of the Currency Gene Ludwig, the network targets an MVP in March, a pilot in Q3, and full customer rollout in Q4 2026. [RELEASE]
Why this matters: BlackRock, Morgan Stanley, and JPMorgan all ran private and permissioned blockchain experiments first, then graduated to public chains like Ethereum and Solana for live products, with BlackRock’s BUIDL fund and Franklin Templeton’s BENJI being the clearest examples. The regional banks building Cari on a permissioned network today may be on the same trajectory. With the GENIUS Act regulatory clarity may be exactly what pushes regional banks to eventually move from permissioned networks to public blockchains.
Santander and Mastercard complete Europe’s first AI agent payment
On March 2, Banco Santander and Mastercard completed Europe’s first live payment executed entirely by an AI agent inside a regulated bank, on real rails, with real money. The AI agent acted within rules set in advance by the user — a spending limit, approved merchant types, and a time window — completing the purchase without any human involvement at checkout. DBS in Singapore and Commonwealth Bank of Australia have run similar pilots under both Visa and Mastercard. [RELEASE]
Why this matters: AI agents are becoming a new buyer class, and the $5 trillion checkout is being rebuilt around them. Card rails settling in 3–5 days can’t support machine-speed transactions, making stablecoins the natural settlement layer and Mastercard is already there, enabling stablecoin spending at 150M+ merchant locations via Circle, MetaMask, and OKX. The real stakes sit in the standards battle: Stripe and OpenAI back one protocol, while Google, Visa, Shopify, and Walmart back a rival open standard — and whoever wins controls how $3T–$5T in annual agent-driven commerce gets routed, discovered, and settled.
