Bitcoin treasury companies lose $80B as business model unwinds

For about 18 months, the playbook seemed bulletproof: buy Bitcoin, tell Wall Street about it, watch your stock price rip. That playbook just lost $80 billion.

The 50 largest public companies holding Bitcoin on their balance sheets saw their combined market capitalization plummet from $150 billion in July 2025 to just $67 billion by August 2026, according to the Financial Times. The digital asset treasury model, which turned obscure software firms and shell companies into proxy Bitcoin ETFs with leverage, is now unwinding in spectacular fashion.

Strategy’s outsized collapse

If one company defined the Bitcoin treasury era, it was Strategy, the firm formerly known as MicroStrategy. And its decline accounts for nearly all of the carnage.

Strategy alone lost approximately $79 billion from its peak valuation. That means virtually the entire $83 billion wipeout across the top 50 can be traced back to a single company’s stock deflating.

Of the 50 largest Bitcoin treasury companies, 43 are now trading below the share prices they had before they pivoted to a Bitcoin-centric strategy. That’s 86% of the cohort performing worse than if they’d simply done nothing.

Even more painful: 35 of those 50 companies have lost at least half their value. Not 10%. Not 20%. Fifty percent or more, gone.

From buyers to sellers

The most telling signal of the model’s breakdown came in July 2026, when the top 50 companies collectively became net sellers of Bitcoin for what appears to be the first time since the treasury trend began. They offloaded 2,500 more Bitcoin than they purchased in a single month.

That shift matters enormously. The entire thesis behind Bitcoin treasury companies rested on a reflexive loop: issue stock or debt at inflated valuations, use the proceeds to buy Bitcoin, point to the Bitcoin holdings to justify the inflated valuation, repeat. When the loop runs in reverse, companies need to sell Bitcoin to cover operational costs, service debt, or fund share buybacks designed to stop the bleeding in their stock price.

Bitcoin itself peaked above $126,000 in October 2025 before the broader market downturn set in.

The copycat problem

During 2024 and 2025, a wave of companies across multiple continents adopted the Bitcoin treasury playbook. Japan’s Metaplanet became one of the most prominent international examples, while the UK’s Smarter Web Company pivoted from its original business to focus on Bitcoin accumulation.

The pattern was remarkably consistent. A company with a stagnant or declining legacy business would announce a pivot to holding Bitcoin as a treasury reserve asset. Its stock would surge on retail enthusiasm and the implicit leverage embedded in the strategy. Management teams would raise capital through secondary offerings or convertible debt, using the inflated stock price as currency.

The more fundamental question is whether the entire concept of a Bitcoin treasury company was ever viable, or whether it was simply a leveraged bet dressed up in corporate strategy language. Spot Bitcoin ETFs, which launched in the US in January 2024, gave investors direct, low-cost exposure to Bitcoin without the management risk, dilution, or premium embedded in treasury company stocks.
