Coinbase adds ex-xAI CFO Anthony Armstrong to its board
Coinbase has appointed Anthony Armstrong, the former finance chief at Elon Musk’s xAI and X, to its board of directors as competition in the cryptocurrency industry increasingly shifts from trading volume to control of the technologies behind 24/7 markets.
In this environment, the ability to provide liquidity, settlement, custody, and regulatory mechanisms for trading outside conventional hours is becoming more important than simply giving individuals the ability to buy Bitcoins. Coinbase is betting that Armstrong’s combination of Wall Street deal-making experience, government knowledge, and experience working at Elon Musk’s companies will strengthen its competitive position.
Board seat, committee role, and expanded board size
Coinbase announced Armstrong’s appointment publicly on September 2. According to the company’s SEC filing, the appointment became effective on September 1. Armstrong will also join the Audit and Compliance Committee, and his addition increases Coinbase’s board from nine directors to ten.
The SEC filing also stated that Anthony Armstrong and Brian Armstrong, Coinbase co-founder and CEO, are not related.
Coinbase said Anthony Armstrong has a record of “building things that work at scale, without waste,” linking his appointment to the company’s emphasis on efficient execution.
From Morgan Stanley to Musk’s companies
Armstrong spent nearly a decade at Morgan Stanley, where he eventually became vice chairman of investment banking after helping lead the firm’s global technology M&A business. He later served as a senior adviser at the Department of Government Efficiency before becoming CFO across xAI, X.AI Corp. and X Corp.
In October 2025, Cryptopolitan reported that Armstrong advised Musk on the acquisition of Twitter for $44 billion and had a strong working relationship with him. The same report said Musk later brought together X and xAI in a deal worth around $113 billion.
That background makes Armstrong more than a routine governance appointment. Coinbase’s future could depend on acquisitions, partnerships, and integrations across securities, crypto markets and blockchain settlement, areas where his deal-making experience may prove useful.
Appointment comes amid weaker results and share-price pressure
The new board member arrives as Coinbase faces weaker financial results and a sharp decline in its share price. According to The Block, COIN closed at $174.96 on September 2, more than 40% below its level a year earlier.
Coinbase’s quarterly report showed a second-quarter loss of $359.5 million on revenue of $1.2 billion. Subscription and services revenue totaled $555.1 million, and the company said 88% of total revenue came from operations other than Bitcoin spot trading. Quartz reported that the company missed Wall Street expectations for three consecutive quarters.
Brian Armstrong summarized the company’s broader strategy during the earnings release by saying Coinbase is “no longer a bet just on the price of Bitcoin.”
Coinbase’s everything-exchange strategy and the race for infrastructure
Coinbase’s “everything exchange” strategy is narrowing the gap between a crypto exchange and a broader multi-asset financial platform. The company has rolled out U.S. stock and ETF trading and prediction markets, while also outlining plans for tokenized assets, pre-IPO perpetual futures, unified liquidity and an SEC-registered AI investment adviser, according to Cryptopolitan.
The market opportunity is already visible in the numbers. CoinGecko said TradFi/RWA perpetual trading volume reached $347.17 billion in May 2026, up from just $230 million at the start of 2025.
At the same time, regulation and market structure may be as important as product expansion. The World Federation of Exchanges has warned that fragmented tokenized-equity markets could weaken liquidity and price discovery.
Traditional exchanges are also moving into the same area. Reuters reported that London Stock Exchange Group is partnering with Kraken parent Payward on tokenized UK shares, with xStocks planned for its 24-hour LSE 24 venue in 2027, subject to regulatory approval.
That raises Coinbase’s strategic challenge. Winning the 24/7 market may depend less on listing the most assets than on controlling the regulated rails that allow capital to move continuously between them.
