A Bitcoin treasury company is a publicly listed firm that uses its stock market access to raise money — through share sales, debt, or hybrid securities — specifically to buy and hold Bitcoin on its balance sheet. The core idea is simple and slightly absurd: investors in the stock market will pay roughly $2 for every $1 worth of Bitcoin the company owns. That premium is the engine. Companies use it to sell overvalued stock, buy more Bitcoin, push the Bitcoin price higher, which pushes their stock higher, which lets them sell more stock. Repeat until further notice.

This is how a struggling British web design firm called Smarter Web Company went from a £4 million valuation to over £1 billion in just two months — simply by announcing it would start buying Bitcoin. No new product. No new customers. Just Bitcoin.

What Is a Bitcoin Treasury Company?

At its core, a Bitcoin treasury company is a publicly traded firm that has pivoted — sometimes entirely — from its original business to accumulating Bitcoin as its primary asset. Many of these companies still technically operate in their original industry, whether that's web design, hotel management, healthcare, or video game retail. But the real business is the Bitcoin pile and the financial engineering around it.

The strategy works because public equity investors appear willing to pay a significant premium over the net asset value (NAV) of the Bitcoin these companies hold. That premium creates a perpetual funding loop: sell stock at a premium, buy Bitcoin, watch Bitcoin and stock price rise, sell more stock, buy more Bitcoin. As one financial commentator put it, it's a financial perpetual motion machine — and once someone discovers it, everyone copies it.

More than 130 listed companies now collectively hold over 800,000 bitcoins — that's more than 3% of the total supply ever available. They span industries as different as gold mining, AI software, Japanese hotel development, and opioid healthcare. What unites them is a shared belief that Bitcoin can do what their actual business could not: ignite investor enthusiasm and turbocharge their share price.

How Did MicroStrategy Turn Bitcoin Into a $100B Company?

MicroStrategy — now rebranded simply as Strategy — is where this all began. Before its Bitcoin pivot, it was a business intelligence and data analytics software company that went public during the dot-com boom in 1998. The company has a colorful history: it was forced to restate two years of financial results in 2000 due to accounting irregularities, triggering one of the first major corporate scandals of the dot-com crash. Its CEO, Michael Saylor, later settled for $40 million over what the DC Attorney General described as the largest income tax fraud in Washington's history.

None of that matters much now, because Saylor figured something out that nobody else had: stock market investors would pay a large premium to own a company that owns Bitcoin, compared to just owning Bitcoin directly. Strategy's core software business generates tiny revenues and operates at a loss. Yet the company is worth over $100 billion. The gap between the value of its Bitcoin holdings and its market capitalisation is the premium — and that premium is the product.

By selling shares at that inflated price and using the proceeds to buy more Bitcoin, Strategy effectively prints money. The efficient markets hypothesis would suggest this shouldn't be possible. It is, apparently, very possible. Saylor has been vocal about encouraging other large companies — including Microsoft — to adopt the same approach, which happens to be very convenient given that he owns a lot of Bitcoin and would benefit enormously from increased institutional demand pushing the price higher.

Why Are Companies Buying Bitcoin Instead of Running Their Business?

For many of the firms that have made this pivot, the honest answer is: because their actual business wasn't working. Bluebird Mining Ventures was struggling with project delays and financial losses before crediting its Bitcoin strategy with reviving shareholder interest and securing new funding. A Chinese AI software company called Next Technology Holding was on the verge of being delisted from NASDAQ when it used the same playbook to boost its share price and stay listed.

Then there's the regulatory angle. In the UK, retail investors are banned from buying exchange-traded products linked to cryptocurrencies. Bitcoin treasury company stocks listed on the London Stock Exchange or the Aquis exchange give British investors a way to get crypto exposure through a familiar vehicle — a regular equity — even if they end up paying a substantial premium for the privilege.

In the US, the political environment has shifted dramatically in crypto's favour. The SEC has dropped or paused more than a dozen cases, the Department of Justice disbanded its crypto enforcement team, and senior politicians have described Bitcoin as part of the mainstream economy. That political tailwind has made it far easier — and far more fashionable — for companies to announce Bitcoin treasury strategies and watch their share prices respond accordingly.

Which Companies Have Become Bitcoin Treasury Firms?

The list is broader and stranger than you might expect:

  • Strategy (formerly MicroStrategy) — The original. A US software company that is now effectively a leveraged Bitcoin holding vehicle.
  • Metaplanet — A Japanese hotel developer whose CEO described himself as transitioning from hotel operator to hodler. The stock is up nearly 600% over the past year after announcing plans to raise approximately $5.4 billion for Bitcoin purchases.
  • Tesla — Bought $1.5 billion in Bitcoin in 2021, sold 75% a year later, and is now once again a significant holder. It reported a $600 million earnings boost last year from rising crypto values under new accounting rules.
  • GameStop — Yes, the video game retailer. It announced Bitcoin purchases, and its stock fell 10%. Investors apparently prefer it to focus on the thriving business of selling Pokémon cards in mall locations.
  • Trump Media — The media company associated with the US president's family confirmed plans to raise $2.5 billion to buy crypto.
  • 21 Capital — Backed by SoftBank and stablecoin operator Tether, connected to figures including Jack Mallers and Brandon Lutnick, son of Commerce Secretary Howard Lutnick.
  • Smarter Web Company — The British web design firm that went from £4 million to over £1 billion in valuation in two months.
  • Nakamoto Holdings — A SPAC that merged with an opioid healthcare group called Kindly MD to create a Bitcoin treasury vehicle. Yes, really.

In just the final week of June alone, at least nine UK-listed companies announced Bitcoin treasury plans or purchases.

How Do Convertible Bonds Fund Bitcoin Purchases?

Beyond selling equity, many of these companies — Strategy in particular — raise money through convertible bonds. These are debt instruments that pay a lower fixed interest rate than regular bonds but give the holder the option to convert their bonds into shares at a pre-agreed price, letting them benefit from any stock price upside.

Because Strategy's stock is extraordinarily volatile — more volatile, in fact, than the underlying Bitcoin — it can issue convertible bonds with unusually high conversion premiums and sometimes at zero interest. Investors accept those terms because the potential upside from the stock is so large.

There's an interesting wrinkle here. Convertible bond investors typically hedge their equity exposure dynamically — buying the stock when it falls and selling when it rises — which would normally dampen the stock's volatility. But Strategy also has a large number of investors in leveraged ETFs that track its stock, and leveraged ETFs do the opposite: they amplify volatility. The two groups are essentially offsetting each other in a strange financial tug of war, with the bond holders trying to smooth the ride and the ETF buyers making it bumpier.

Is the Bitcoin Treasury Strategy Just a House of Cards?

That depends entirely on what Bitcoin does next. If Bitcoin continues to rise, the strategy looks like genius. Companies that leveraged up to buy it will report enormous paper gains, their stock prices will stay elevated, and they'll be able to service any debt they've taken on with ease.

If Bitcoin enters a prolonged bear market, the picture changes dramatically. Many of these firms have taken on significant debt to fund their purchases. A sharp sustained decline in Bitcoin's price could leave them unable to service that debt, with balance sheets full of a depreciating asset and no underlying business generating enough cash to cover the gap. Bitcoin treasury strategies have not yet been tested by a serious crypto winter. That test may still be coming.

There's also a governance dimension. Not all shareholders signed up to own a crypto fund when they bought into a hotel company or a web design firm. As long as share prices are rising, dissenting investors can simply sell. When the music stops, boards will have some very uncomfortable questions to answer.

How Has Bitcoin's Identity Changed Over Time?

Bitcoin was created in 2008 as a direct response to the global financial crisis — a decentralised, transparent, user-controlled alternative to the centralised banking system that had just nearly collapsed. It was meant to be a currency: peer-to-peer, trustless, free from institutional control.

When its price started rising sharply, using it as a currency became impractical. Nobody spends an appreciating asset. So it became an investment. Then it was repositioned as digital gold — a store of value, a hedge against inflation. That story ran into trouble when Bitcoin fell sharply during the post-pandemic inflation surge, at the exact moment you'd expect a genuine inflation hedge to perform.

Now the pitch is something else entirely: get exposure to Bitcoin by buying a locally listed stock at a large premium to NAV, denominated in your own currency, through your regular brokerage account, in a company run by someone who used to clean hotel rooms or sell business intelligence software. This is the opposite of decentralisation. It's Bitcoin being absorbed back into the very institutional financial infrastructure it was designed to escape.

Whether that's a triumph of adoption or a betrayal of the original idea is a philosophical question. Whether it's a sound investment strategy is a financial one. The answer to both, for now, remains genuinely unclear.
