Why Peter Thiel’s Founders Fund Exited Its Ether Treasury Investment

Key Points

• The decision by Founders Fund to exit ETHZilla highlights the structural risks of leveraged crypto treasury strategies.
• Ether treasury companies face unique operational complexity compared with Bitcoin-focused balance sheet strategies.
• Debt obligations combined with crypto volatility can force companies to sell assets at unfavorable times.
• Institutional investors increasingly prefer direct exposure to digital assets instead of investing through leveraged public companies.
• The ETHZilla case illustrates how capital structure, risk management and market cycles shape the sustainability of crypto treasury models.

The Rise of Ether Treasury Companies

In recent years, a new corporate strategy emerged within the crypto ecosystem: companies transforming their balance sheets into digital asset treasuries. Inspired by the success of Bitcoin treasury strategies adopted by firms like MicroStrategy, some companies attempted to replicate the model with Ethereum.

One of the most ambitious examples of this approach was ETHZilla. Originally operating as a biotechnology company under the name 180 Life Sciences, the firm executed a dramatic strategic shift in 2025. Instead of focusing on medical research, the company pivoted toward becoming a publicly traded vehicle designed to accumulate Ether and provide investors with indirect exposure to the cryptocurrency market.

The strategy attracted significant attention from investors. In July 2025, the company raised approximately $425 million to build its Ether reserves. Soon after, it attempted to secure an additional $350 million through convertible bond offerings. The goal was simple in theory but bold in execution: acquire large amounts of Ether, hold the assets on the company’s balance sheet and potentially generate additional yield through staking or decentralized finance activities.

At its peak, ETHZilla reportedly held more than 100,000 ETH, positioning itself as one of the largest corporate holders of Ethereum. For investors who wanted exposure to the cryptocurrency through traditional equity markets, the company represented an appealing gateway.

Yet beneath the surface, the strategy contained significant structural risks.

Peter Thiel’s Founders Fund and the Initial Bet

Peter Thiel has long been known as one of Silicon Valley’s most unconventional investors. As the co-founder of PayPal and an early backer of Facebook, Thiel built a reputation for identifying transformative technological trends long before they reached mainstream recognition.

Through his venture capital firm, Founders Fund, Thiel has supported a wide range of disruptive ventures across technology, aerospace and artificial intelligence. Crypto assets have also appeared in the firm’s investment portfolio.

In 2025, regulatory filings revealed that entities connected to Founders Fund had taken a notable stake in ETHZilla, holding roughly 7.5% of the company. The investment signaled confidence in the emerging concept of Ether treasury companies and their potential to serve as public market proxies for digital asset exposure.

However, the position would not last long.

When Market Reality Meets Leverage

As the crypto market cooled after the highs of 2025, ETHZilla’s ambitious treasury strategy began to face serious pressure. Ether prices declined significantly from earlier levels, reducing the value of the company’s balance sheet.

The situation became particularly challenging because the company had relied heavily on debt financing. Borrowed capital allowed ETHZilla to accumulate more Ether, amplifying gains during favorable market conditions. But when prices dropped, leverage turned from an advantage into a liability.

In December 2025, the company made a pivotal move: it sold 24,291 ETH, raising approximately $74.5 million at an average price of around $3,068 per coin. The purpose of the sale was not portfolio rebalancing or strategic repositioning. Instead, the funds were required to meet debt obligations.

For a company whose identity was built around holding Ether, selling a substantial portion of its holdings to service debt raised important questions about the resilience of the model.

Following the transaction, ETHZilla’s Ether reserves reportedly fell to around 69,800 ETH.

The event exposed one of the core vulnerabilities of leveraged crypto treasury strategies. When debt is involved, market downturns can trigger forced asset sales. Instead of patiently accumulating assets over the long term, companies may find themselves liquidating holdings precisely when prices are weakest.

The Quiet Exit

Shortly after ETHZilla’s Ether sale, regulatory filings revealed another development. Entities linked to Founders Fund had reduced their ownership stake in the company to zero by the end of 2025.

The disclosure appeared in an amendment to a Schedule 13G filing submitted to the U.S. Securities and Exchange Commission. These filings are typically used by investors who hold passive stakes in publicly traded companies.

When such a filing indicates that an investor no longer holds shares above the reporting threshold, it effectively signals a complete exit from the position.

Importantly, these filings do not explain the reasons behind the decision. Investors are not required to disclose whether the move reflects a portfolio rebalancing, a reassessment of risk, or broader concerns about the company’s strategy.

Nevertheless, the timing of the exit—coming shortly after ETHZilla’s forced Ether liquidation—naturally drew attention across financial and crypto markets.

Ether Treasury Strategies Are Not the Same as Bitcoin Treasuries

Comparisons between Ether and Bitcoin treasury strategies are inevitable. However, the two approaches differ in several fundamental ways.

Bitcoin treasury models are relatively straightforward. Companies accumulate Bitcoin as a long-term store of value and simply hold it on their balance sheets. The investment thesis relies primarily on Bitcoin’s scarcity, predictable monetary policy and growing institutional adoption.

Ether treasury strategies introduce additional layers of complexity.

Ethereum is not just a digital asset but also the fuel that powers a programmable blockchain ecosystem. Companies holding large amounts of Ether often pursue strategies aimed at generating yield, such as staking or participating in decentralized finance protocols.

While these activities can enhance returns, they also introduce operational risks that Bitcoin treasury companies generally avoid. Smart contract vulnerabilities, validator penalties, liquidity lock-ups and counterparty exposures all become relevant considerations.

This added complexity can make it harder for investors to evaluate the true risk profile of Ether treasury companies.

Market Narratives and Investor Psychology

Another factor shaping investor behavior is narrative clarity. Bitcoin has spent more than a decade building its identity as  digital gold,  a scarce asset that serves as a hedge against monetary expansion.

Ethereum’s narrative is broader and more dynamic. The network supports decentralized applications, tokenized assets, decentralized finance and nonfungible tokens. While this versatility creates enormous innovation potential, it also introduces uncertainty.

Network upgrades, competition from alternative blockchains, regulatory developments and fluctuating transaction fees all influence Ethereum’s ecosystem.

For investors seeking a simple macro thesis, Bitcoin’s narrative may feel easier to understand and evaluate.

The Capital Structure Challenge

The ETHZilla case also highlights an important financial concept: capital structure risk.

During bullish markets, companies with crypto-heavy balance sheets can benefit from a positive feedback loop. Rising asset values increase net asset value, which may push the company’s share price higher. This allows firms to issue new equity or convertible instruments to raise additional capital and purchase more digital assets.

However, the dynamic reverses during downturns.

As crypto prices decline, net asset value falls. Share prices may drop below the value of the underlying assets, making it difficult or expensive to raise new capital. Debt obligations remain fixed, forcing companies to consider selling assets to maintain financial stability.

This reversal can transform a growth-oriented strategy into a defensive one almost overnight.

Direct Crypto Exposure Is Easier Than Ever

Institutional investors today have more options than ever when it comes to gaining exposure to digital assets.

Secure custody solutions allow institutions to hold cryptocurrencies directly. Exchange-traded funds and regulated investment products provide additional pathways into the market. Staking platforms and derivatives markets also offer sophisticated tools for managing risk and generating returns.

Compared with these options, investing in a publicly traded company whose primary strategy is holding leveraged crypto assets may appear unnecessarily complicated.

Equity investors must consider not only the performance of the underlying digital asset but also management decisions, governance structures, financing strategies and operational execution.

For some institutions, simpler exposure may be preferable.

What the Founders Fund Exit Really Means

It would be a mistake to interpret Founders Fund’s exit as a blanket rejection of Ethereum or the broader crypto sector.

Peter Thiel’s investment firm has historically pursued opportunities where technological innovation intersects with long-term economic transformation. The decision to leave a particular company does not necessarily imply a negative view of the underlying technology.

Instead, the move may reflect a more selective approach to how crypto exposure fits within a venture portfolio.

Founders Fund typically invests in high-growth companies building scalable technology platforms. A publicly traded vehicle whose primary strategy revolves around managing a leveraged balance sheet of digital assets may simply fall outside that framework.

The episode serves as a reminder that not all crypto-related investments carry the same risk profile.

The Future of Public Crypto Treasury Strategies

The concept of corporate crypto treasuries is still evolving. Some companies continue to accumulate digital assets with long-term conviction, viewing short-term volatility as a natural part of an emerging financial system.

Others are reconsidering their strategies as market conditions shift.

Ultimately, the sustainability of crypto treasury models depends on several key factors: conservative leverage, disciplined capital management and the ability to withstand prolonged market downturns.

The ETHZilla story illustrates both the potential and the pitfalls of turning a corporate balance sheet into a digital asset investment vehicle.

As institutional participation in crypto markets continues to grow, the industry will likely see new experiments in how companies integrate blockchain assets into their financial strategies.

Some will succeed. Others will reveal the structural weaknesses that must be addressed before the model can mature.
