Wall Street banker, former chief financial officer of Musk, now a director of Coinbase: The story of Anthony Armstrong

Coinbase expanded its board of directors to 10 members by appointing Anthony Armstrong. Armstrong brings a rare combination of experience in Wall Street, artificial intelligence, government and cryptocurrency to Coinbase.

The former Morgan Stanley banker helped Elon Musk complete his $44 billion acquisition of Twitter and later served as chief financial officer (CFO) of xAI and X. His appointment comes as Coinbase deepens its equity, derivatives, and forecast markets businesses and advances its vision of an "Everything Exchange".

In the cryptocurrency industry, board members change from time to time. But occasionally, a board appointment can provide a clearer indication of the company's future direction. That's what made Anthony Armstrong different when he joined Coinbase.

New directors can influence the direction of the exchange's development, the market areas it enters, and the degree of expansion beyond the cryptocurrency space. However, few recent appointments have attracted public attention from the cryptocurrency world to the broader fields of finance and technology as Armstrong's appointment.

This is not only because of his work experience, but also because of the names and institutions with which his career was associated: Morgan Stanley, Elon Musk, xAI, X, the U.S. government, and now Coinbase.

Who is Anthony Armstrong, the new director of Coinbase?

Anthony Armstrong laid the foundation for his career on Wall Street long before he became chief financial officer of Elon Musk's company. He worked at Morgan Stanley for nearly a decade, during which time he established and led the investment bank's global technology M & A business, and eventually rose to vice chairman of investment banking.

This career has put him at the heart of some of the world's largest technology deals. This eventually brought him into Elon Musk's circle. In 2022, Armstrong advised on Musk's $44 billion acquisition of Twitter, one of the most-watched technology deals in the decade. Recently, Elon Musk's SpaceX completed a $60 billion acquisition of Cursor AI startup.

But he did not stop at his role as an external consultant. Armstrong later entered Musk's technology empire and eventually served as chief financial officer at several Musk companies, including xAI, X.AI Corp. and X Corp. This puts him directly at the financial heart of one of the world's most ambitious technology companies, including Musk's layout in artificial intelligence.

Another unusual chapter followed. Armstrong serves as a senior adviser to the Department of Government Efficiency, focusing on studying how large and complex institutions can operate more efficiently.

So when Coinbase invited him to join the board, it was not just adding a former Musk executive, but bringing in a professional with a background in Wall Street trading who had worked with Elon Musk, managed Musk's companies and worked deep into the U.S. government.

In its official announcement, Coinbase also described Armstrong's resume as one of the most distinctive talents its board can recruit, noting in particular his experience in traditional finance, cutting-edge technology and government efficiency.

Coinbase's new chapter

The timing of Armstrong's appointment is perhaps the most important part of this story. Coinbase is trying to redefine the functionality of the exchange.

Brian Armstrong's vision of an "Exchange for Everything" is pushing companies beyond mere places to buy and sell bitcoins and other cryptocurrencies. The company is expanding into derivatives, forecasting markets, stocks and other financial products, trying to consolidate more financial markets under one roof.

Coinbase even dabbled in pre-IPO equity exposure, initially launching a SpaceX-related perpetual contract. It has recently become Canada's first major regulated exchange to offer cryptocurrency perpetual contracts. This week, the company filed an application with the U.S. Securities and Exchange Commission seeking approval to provide equity perpetual contracts, another step into traditional market areas.

This makes Armstrong's background suddenly seem highly relevant. He understands Wall Street, understands technology, understands mergers and acquisitions, and has worked inside the world's most ambitious organizations. These are exactly the worlds Coinbase is now trying to connect.

Armstrong sees the intersection of cryptocurrency and finance

After joining Coinbase, Armstrong's remarks made the move even more eye-catching. "The intersection of regulated financial services and cryptocurrencies is where the most influential work in the industry takes place." Armstrong wrote on Platform X.

Wall Street, Washington, Artificial Intelligence. The intersection of markets, policies and leading technologies builds the future of finance.
This is where Coinbase operates and where my career has been. It's a pleasure to join the board.

This sentence may explain the significance of this appointment more than any other explanation. Coinbase is increasingly positioning itself as a key player at this intersection.

For many years, cryptocurrencies and traditional finance have operated as two separate worlds. Today, boundaries are becoming blurred. Banks are moving billions of dollars into the chain; stocks are also on the chain; private equity exposure is being introduced to cryptocurrency platforms; derivatives are expanding; and the forecast market continues to grow. Exchanges are increasingly competing for the same traders, liquidity and financial activity.

Coinbase wants to be at the center of this transformation. Armstrong's career has traveled between these now converging worlds.

More than just Musk's relationship

Of course, the connection with Elon Musk will be the first thing many people notice. This is indeed an important factor. Armstrong advised Musk on the Twitter acquisition and later became the chief financial officer of several Musk companies.

But simply calling him "Elon Musk's chief financial officer" would underestimate his resume. Before Musk, there was Morgan Stanley; before Coinbase, there was the experience of Wall Street, government, AI and X. Now, all of this experience has been brought together in the cryptocurrency giant.

Coinbase said Armstrong has always been focused on building a company that can operate at scale without redundancy and waste. This is closely consistent with Coinbase's own operating principles.

This may be critical as Coinbase expands in size and ambitions. Because building an "Everything Exchange" is not just about adding more assets. This means building the infrastructure, risk controls, compliance systems and the financial architecture needed to handle the broader market universe.

It is in these respects that Armstrong's financial background may become particularly valuable.
