Breaking Down Brian Armstrong’s Net Worth in 2025

These days, Armstrong’s net worth comprises not only of his stake in Coinbase and his crypto investments, but also his profits from sold Coinbase shares and profits from his other venture, NewLimit.

While the details remain largely undisclosed, as can be expected, we have gathered sufficient data to make a detailed breakdown of his net worth.

Brian Armstrong Net Worth: Early Life and Education

Brian Armstrong was born on January 25, 1983, in San Jose, California. His parents both worked as engineers at the forefront of their fields. “My mom worked at IBM. She was one of the early women computer programmers,” – Brian Armstrong said in the documentary “COIN: Brian Armstrong: A Founder’s Story.”

Brian was very interested in computers from an early age, so his parents shopped around, looking for a used computer to buy for him.

Armstrong attended Bellarmine College Preparatory, an all-male, Catholic private secondary school. After graduation, he enrolled at Rice University in Texas, where he earned a dual Bachelor’s degree in economics and computer science in 2005.

Armstrong then enrolled in a Master’s program at Rice, earning his degree in computer science in 2006. While he was still a student, Armstrong started his first business, a website named University Tutor, that matched tutors with students.

“In high school, I built this website. I remember, I went to sleep and woke up in the morning and I checked the stats and, like, a thousand people looked at it while I was sleeping… And when I went to college, my roommate and I were trying to think about how to make some extra cash. And I realized if we were to tutor high school students, we could make great money”. – Brian shared in the documentary.

In October 2024, Armstrong married his long-term partner, Angela Meng.

Brian Armstrong’s Early Career Days and the Birth of Coinbase

Before Brian Armstrong cofounded Coinbase and turned it into one of the world’s largest cryptocurrency exchanges, he had a successful tech career. Let’s see how his career led him to billionaire status.

Early Career

University Tutor was successful shortly after it was launched, but Armstrong wanted to move on to greener pastures, so he sold it after he graduated from college. He then spent a whole year in Buenos Aires, working for an education company.

Armstrong continued to move up in the world soon after college, working for free as an IBM developer and even worked as a consultant for Deloitte for a short stint. Around this time, he discovered the emerging world of blockchain technology and was enthralled by its ingenuity and sheer potential.

Discovering Crypto and Founding Coinbase

In 2010, Armstrong discovered Satoshi Nakamoto’s Bitcoin whitepaper, changing his life forever.

“Around Christmas time, 2010, I came back to California and I was just home with my family and I happened to come across the Bitcoin Whitepaper… It was describing something kind of like the Internet that was global and decentralized that no company or country owned. I thought “Oh my gosh, this could have an enormous impact on the world” – Amstrong remembers in his documentary.

A year later, he joined Airbnb as a software engineer, where he encountered challenges in cross-border payments, most particularly in Latin America. His experience at Airbnb reinforced his belief in the need for a decentralized financial system, and he couldn’t stop thinking about Bitcoin. He believed in its potential but felt like the world needed someone to make it easier to use and trade.

In 2012, Brian Armstrong entered the Y Combinator startup accelerator contest with his idea for Coinbase. The company gave him a $150,000 investment for his new business.

“The minute I got accepted into Y Combinator, I decided I was quitting my job at Airbnb and starting this new company” – he shared.

Teaming up with Fred Ehrsam, who he met on an online forum, Armstrong cofounded Coinbase in San Francisco to simplify cryptocurrency transactions for users.

Ehrsam is a former Goldman Sachs trader who noticed Armstrong’s posts on Reddit and liked his idea of the new brand. Been Reeves, a British programmer and cofounder of Blockchain.info was initially meant to be part of the founding team, too, but he parted ways with Amstrong just before the Y Combinator funding round due to differing views.

The name of the company, Coinbase, refers to a type of transaction used in proof-of-work cryptocurrencies that introduces new coins into circulation. In October 2012, Coinbase officially launched its platform, allowing users to trade Bitcoin through bank transfers.

As its first CEO, Brian Armstrong led Coinbase to tremendous growth. In its early days, he developed a crypto wallet called “Toshi”, inspired by the pseudonymous creator of the Bitcoin white paper, Satoshi Nakamoto.

The company quickly gained traction and attracted significant investments, such as the $25 million investment from the venture capital firms Andreessen Horowitz, Ribbit Capital, and USV; as well as the $75 million investment by the New York Stock Exchange, USAA, and several banks.

In the COIN documentary, Armstrong and Ersham share their life stories and tell us how they founded Coinbase. In a celebratory moment captured in a behind-the-scenes video, Armstrong and Vitalik Buterin, Ethereum’s cofounder, shared an iconic exchange when Coinbase received a significant financial boost.

You can watch the full documentary on YouTube below:

By 2018, a new funding round valued Coinbase at $8.1 billion. That same year, Coinbase formed an early-stage venture fund called Coinbase Ventures, focusing on investments in blockchain companies.

In December 2020, the business took a major step toward mainstream financial markets when it filed with the SEC for a public listing. In April 2021, Coinbase went public through a direct listing on the Nasdaq exchange, achieving an impressive market capitalization of $100 billion on its debut.

As of 2025, Coinbase is the world’s largest custodian of Bitcoin. The company holds over 12% of all Bitcoin in existence. By the end of 2024, the company shared that it was managing digital assets worth $404 billion.

Brian Armstrong’s Stake in Coinbase

Brian Armstrong, as the company’s CEO and cofounder, saw his personal wealth grow significantly as Coinbase grew exponentially. Even today, most of his wealth comes from his stake in Coinbase.

Based on the valuation in 2021, Armstrong’s 19% stake in Coinbase was worth $19 billion. As of March 2025, Coinbase Global Inc. has a market capitalization of over $47.57 billion, but Armstrong’s stake has decreased to less than 14%.

This suggests that Brian Armstrong has sold a portion of his stake in Coinbase since 2021. He likely liquidated shares either for personal wealth, diversification, or other strategic reasons. The exact value at which he sold his shares remains unknown, as market conditions and Coinbase’s stock valuation fluctuated over time.

Considering the trajectory of Coinbase’s valuation, he most likely earned billions from the stock sale. Just recently, he sold $100 million of Coinbase shares a week after the election in 2024. The following week, he sold $313 million worth of shares, which is reportedly part of a trading strategy he set in motion as the share’s price spiked. Since then, Armstrong has been selling smaller amounts week after week, adding up to a total of $437 million worth of stock.

Back in 2021, his 19% stake in Coinbase would be worth $19 billion. As of March 2025, Coinbase is reportedly worth around $47.57 billion. If Armstrong still held a 19% stake, it would be worth $9 billion today. However, recent reports indicate that his ownership has decreased to 13.91%, with his latest disclosure revealing that he still owned 33,103,998 shares in Coinbase. Based on this figure, his stake in the business is now worth over $6.5 billion.

Coinbase’s Controversies

Brian Armstrong’s Coinbase has faced various controversies and legal challenges over the years.

In 2017, Coinbase was ordered by the U.S. Internal Revenue Service (IRS) to disclose the identities of users who had transacted over $20,000 in a year. This move was part of efforts to ensure tax compliance with earnings in the crypto industry.

That same year, Coinbase faced an insider trading investigation related to the listing of Bitcoin Cash, where the platform experienced price abnormalities that raised many questions about possible market manipulation.

When Coinbase obtained a BitLicense from the New York State Department of Financial Services, allowing it to operate legally in New York, the move was met with heavy criticism. Many people in the crypto community argued that such regulations restrict innovation.

In 2018, Coinbase disclosed to around 13,000 users that their tax records from 2013 to 2015 would be handed over to the IRS as part of an investigation. This raised more concerns about privacy and the company’s handling of user data.

In 2019, Coinbase’s acquisition of the blockchain intelligence company Neutrino sparked considerable controversy. Neutrino’s founders had previously worked with Hacking Team, a company that was allegedly involved in surveillance and human rights abuses. The backlash led to Brian Armstrong apologizing for the lack of due diligence in the deal. The crypto exchange ultimately fired some of the employees connected to the controversial firm.

More recently, in 2023, Coinbase became entangled in a legal battle with the SEC. The SEC alleged that the crypto exchange Coinbase was operating as an unregistered securities broker, demanding that they cease all operations as such until it was registered properly. The SEC’s investigation was focused on Coinbase’s staking services and the company filed a lawsuit against the SEC in response.

Coinbase reached an agreement to have the SEC’s litigation dismissed in February 2025 with no fines and no changes to its business. Armstrong spoke about the agreement in a recent statement on X, which you can see below.

This wasn’t the first or only battle between Coinbase and the SEC. In 2021, Coinbase was under investigation by the SEC over its plans to offer cryptocurrency lending services, specifically a product called Lend, which would allow users to earn interest on their crypto holdings. The investigation led to Coinbase dropping their project.

Coinbase has also been accused of listing coins that have been deemed to be securities by the SEC. These include assets such as Ripple and other altcoins, which have led to legal disputes between Coinbase and the SEC.

Brian Armstrong’s wealth mostly stems from his stake in Coinbase, as well as his crypto holdings. However, he has built his fortune with a variety of other projects.

In May 2023, New Limit raised $40 million in a Series A investment round to continue its research.

Armstrong’s stake in NewLimit has not been publicly disclosed. As a cofounder, he likely holds a significant stake in the company. Since NewLimit is a private company, detailed financial information, such as its valuation, is not publicly disclosed.

Political Activities

Over the years, Armstrong and Coinbase have used significant financial backing to support political candidates who align with their pro-crypto stance. The Fairshake PAC (Political Action Committee) has been funded largely by Coinbase and played a major role in the 2024 U.S. election cycle, supporting candidates who favored crypto-friendly policies.

Armstrong has been an influential backer of candidates like Ohio Republican Bernie Moreno, whom he met with multiple times to discuss the future of blockchain technology and crypto policy. Moreno was challenging the incumbent Sherrod Brown, who had been quite critical of cryptocurrencies. Following Moreno’s victory, Armstrong shared the following on his X profile:

“Moreno understands that crypto is an important part of America’s future. Bernie and the crypto owners who helped him secure this win understand how everyone can benefit from crypto and are willing to fight for it. Welcome to America’s most pro-crypto Congress ever.”
