Bitcoin, the first and most prominent cryptocurrency, has garnered widespread attention since its creation in 2009. With growing institutional interest, many wonder: Which organization holds the most Bitcoin in 2025?
As of now, several organizations and companies have made significant investments in Bitcoin, holding vast amounts of the digital asset. Here, we explore the top organizations and their Bitcoin holdings, with a focus on the year 2025.
1. Satoshi Nakamoto: The Largest Bitcoin Holder
Before diving into contemporary institutional holders, it’s important to note the largest known holder of Bitcoin—the mysterious creator of the cryptocurrency, Satoshi Nakamoto. Although the true identity of Nakamoto remains a mystery, it is believed they mined around 1 million bitcoins in the early days of Bitcoin’s existence. As of 2025, these coins remain untouched, making Satoshi the largest holder.
Though these coins haven’t moved, Nakamoto’s stash remains a significant part of Bitcoin’s supply and has sparked much curiosity. However, as these coins remain dormant, Nakamoto’s holdings don’t affect the market, leaving room for other organizations to emerge as active Bitcoin holders.
2. MicroStrategy: Leading the Corporate Bitcoin Rush in 2025
As of 2025, the American business intelligence firm MicroStrategy holds the most Bitcoin among publicly traded companies. MicroStrategy’s Bitcoin holdings surpass 120,000 BTC, making it the largest corporate Bitcoin holder. This strategic decision began in 2020 under the leadership of CEO Michael Saylor, who saw Bitcoin as a hedge against inflation and a store of value.
MicroStrategy’s consistent purchasing of Bitcoin has made it a major player in the Bitcoin market. The company’s holdings are stored securely in cold storage, and its Bitcoin strategy has influenced many other companies to consider Bitcoin as part of their treasury management.
3. Tesla’s Bitcoin Holdings in 2025
Electric vehicle manufacturer Tesla has also been a significant player in the Bitcoin market. In early 2021, Tesla purchased $1.5 billion worth of Bitcoin, making headlines in the corporate world. By 2025, Tesla still holds a notable amount of Bitcoin, with estimates suggesting the company owns around 42,000 bitcoins.
While Tesla has sold off a portion of its Bitcoin holdings over the years, it continues to hold Bitcoin as part of its treasury reserve strategy. Tesla’s involvement in Bitcoin has further helped mainstream cryptocurrency adoption, especially in the corporate sector.
4. Grayscale Bitcoin Trust (GBTC): A Major Institutional Player
Another top contender in the race for the most Bitcoin is Grayscale Bitcoin Trust (GBTC). As of 2025, GBTC holds more than 600,000 bitcoins on behalf of institutional investors. GBTC provides a regulated and accessible way for institutional investors to gain exposure to Bitcoin without directly owning or managing the cryptocurrency.
This makes Grayscale a critical player in the Bitcoin market, and its large holdings reflect the growing institutional demand for Bitcoin. The trust’s shares trade on public markets, offering liquidity while ensuring safe, regulated access to Bitcoin.
5. Block.one: EOS Blockchain’s Bitcoin Holdings in 2025
Block.one, the company behind the EOS blockchain, is another significant Bitcoin holder. As of 2025, Block.one owns around 140,000 bitcoins. The company accumulated these coins during its initial coin offering (ICO) and has held them as part of its treasury. While its main focus remains on the EOS blockchain, its Bitcoin holdings play a crucial role in its overall financial strategy.
Block.one’s decision to hold Bitcoin is a testament to the strategic role that cryptocurrency plays for blockchain-related companies. Its significant holdings contribute to its standing as one of the largest Bitcoin holders in 2025.
6. Other Organizations Holding Bitcoin in 2025
Several other organizations hold significant amounts of Bitcoin in 2025, contributing to the growing institutional adoption of the digital asset. These include:
- Coinbase: As one of the largest cryptocurrency exchanges globally, Coinbase holds substantial amounts of Bitcoin, primarily in its user wallets. While these holdings are not exclusively owned by Coinbase itself, the exchange’s volume and market presence make it a major entity in Bitcoin’s ecosystem.
- Bitfinex: Another major cryptocurrency exchange, Bitfinex, is known for holding a large number of Bitcoin in cold storage. As one of the most active exchanges in the Bitcoin market, Bitfinex plays a crucial role in facilitating large Bitcoin trades.
- SpaceX: In addition to Tesla, SpaceX—Elon Musk’s aerospace company—has also reportedly purchased Bitcoin. As of 2025, SpaceX holds an estimated amount of Bitcoin, further solidifying Musk’s influence in the cryptocurrency space.
Conclusion: Who Holds the Most Bitcoin in 2025?
As of 2025, Satoshi Nakamoto remains the largest known holder of Bitcoin, with over 1 million BTC, though these coins are inactive. However, among active holders, MicroStrategy is the leader with more than 120,000 bitcoins. Tesla, Grayscale Bitcoin Trust, and Block.one are also major institutional holders, showcasing the growing adoption of Bitcoin by corporations and investment vehicles.
With increasing institutional adoption and growing corporate treasuries holding Bitcoin, it is clear that the landscape of Bitcoin ownership continues to evolve in 2025. As the digital asset gains more mainstream acceptance, the question of which organization holds the most Bitcoin will likely continue to evolve.
