Why Do Companies Buy Bitcoin? Corporate Treasuries Explained

A company's treasury is where it keeps its spare cash. For decades, that money sat in bank deposits, money market funds and short-term government bonds. It was safe, boring and predictable.

Then, in 2020, Strategy—then known as MicroStrategy—became the first major publicly traded company to make bitcoin its primary treasury reserve asset. The approach has since spread to dedicated bitcoin treasury companies, conventional operating businesses and public bitcoin miners. Public companies tracked by bitcoin-treasury datasets now collectively hold well over one million BTC, although those holdings are heavily concentrated among a relatively small number of companies.

So why would a business swap cash for bitcoin? This guide explains what a corporate bitcoin treasury is, the main reasons companies buy bitcoin, how they pay for it, the risks involved, and why some businesses choose to mine their bitcoin instead of buying it.

Key Takeaways

• A corporate bitcoin treasury means a company holds bitcoin on its balance sheet as a reserve asset.

• Companies cite inflation protection, bitcoin's fixed supply, diversification and long-term growth potential.

• FASB issued ASU 2023-08 in December 2023, requiring qualifying crypto assets such as bitcoin to be measured at fair value for fiscal years beginning after December 15, 2024, with changes recognized in net income.

• Firms fund purchases with cash, convertible debt or new share sales, and each method has its own risks.

• Bitcoin miners can build treasury positions by earning BTC through mining and retaining some of those rewards, although mining costs can be higher or lower than bitcoin's market price depending on electricity, efficiency, difficulty and other operating conditions.

What Is a Corporate Bitcoin Treasury?

A corporate bitcoin treasury is simply a company holding bitcoin as part of its reserves instead of keeping everything in cash or bonds.

For most companies, bitcoin is a small slice of their reserves. But a new type of business, often called a bitcoin treasury company, makes accumulating bitcoin its core strategy. For these firms, buying bitcoin is not a side bet. It is the business plan.

The Company That Popularized the Corporate Bitcoin Treasury

The company most associated with the modern corporate bitcoin-treasury strategy is Strategy, formerly MicroStrategy. Strategy describes itself as the first publicly traded company to adopt bitcoin as its primary treasury reserve asset, and it publishes a Treasury Reserve Policy explaining its approach.

Fidelity Digital Assets' Adding Bitcoin to a Corporate Treasury notes that Strategy initially acquired 38,250 BTC for about $425 million between July and September 2020. The strategy grew far beyond that initial allocation through cash purchases, debt, equity issuance and other capital-market transactions.

Strategy's holdings have continued to change rapidly. The company reported 848,250 BTC as of October 11, 2026, after purchasing another 250 BTC. Because Strategy frequently raises capital and changes its holdings, use its latest investor-relations disclosures rather than relying on an older fixed number.

Why Do Companies Buy Bitcoin?

1. Protection Against Inflation

Cash and other low-yield assets can lose purchasing power when inflation exceeds the return they earn. Fidelity's research points to the inflation surge that peaked above 9% in 2022 and remained elevated afterward as one reason some corporate treasurers began reconsidering traditional reserve strategies. Bitcoin advocates argue that its fixed maximum supply may provide protection against currency debasement, but that thesis comes with much higher price volatility than cash, Treasury bills or money-market instruments.

2. Fixed, Verifiable Scarcity

Only 21 million bitcoin will ever exist, and anyone can verify that supply on the blockchain. Supporters see this as a hedge against government deficits, currency debasement and geopolitical risk. In OneMiners' Top 10 Cryptocurrencies to Invest in 2026, Bitcoin takes the number one spot, described as a store-of-value asset with a fixed supply whose role has been strengthened by institutional adoption, exchange-traded products and corporate treasury allocations.

3. Diversification

Fidelity's research discusses bitcoin's historically low or changing correlation with many traditional assets as one possible diversification argument. That does not mean bitcoin always moves independently from stocks or other risk assets—correlations can rise sharply during market stress. A bitcoin allocation can therefore add a different source of return to a treasury, but it can also increase overall volatility and drawdown risk.

4. Long-Term Growth Potential

Bitcoin's historical returns have outpaced major benchmarks such as the S&P 500, according to The Block. Fidelity gives an illustration: a 1% allocation ($100 million on a $10 billion treasury) made at $10,000 per bitcoin in June 2019 would have grown to about $700 million by June 2024. Past performance does not guarantee future results, but it explains the appeal.

5. Investor Demand

Some shareholders want bitcoin exposure through a regulated stock rather than holding coins themselves. Companies with bitcoin treasuries can offer exactly that.

6. Growing Regulatory Clarity

Fidelity points to Europe's MiCA framework and the SEC's January 2024 approval of spot bitcoin ETFs as signs that bitcoin is becoming an accepted part of the financial system.

The Accounting Change That Removed an Important Barrier

Before the new fair-value rules, U.S. companies generally accounted for bitcoin under the indefinite-lived intangible-asset model. If bitcoin's value fell below its carrying amount, an impairment could be recorded, while later price recoveries generally could not be marked back up before a sale. That could leave the balance-sheet carrying value well below bitcoin's current market value.

In December 2023, the Financial Accounting Standards Board issued ASU 2023-08, Accounting for and Disclosure of Crypto Assets. For crypto assets within the standard's scope—including bitcoin—the rules require measurement at fair value at each reporting date, with changes in fair value recognized in net income. The amendments became effective for fiscal years beginning after December 15, 2024, with early adoption permitted.

That treatment gives investors a more current view of the market value of a company's bitcoin, but it introduces another trade-off: large bitcoin price movements can now create significant gains or losses in reported quarterly earnings.

Who Holds Bitcoin on Their Balance Sheet?

Bitcoin treasury holdings change frequently, so dates matter. Recent company disclosures show:

The rankings can change quickly as treasury companies issue shares, borrow money, buy bitcoin, sell assets or adjust their strategies. Strategy remains by far the largest corporate holder, accounting for a major share of all bitcoin held by public companies.

Tesla provides a useful reminder that treasury policies can change. It originally bought about $1.5 billion of bitcoin in 2021 and sold a large portion in 2022, while continuing to hold the remainder.

How Companies Pay for Bitcoin

The Block describes three main funding methods:

1. Spare cash. The simplest approach. A company uses existing reserves, which naturally limits how much it can buy.

2. Convertible debt. The company borrows money, often at low or even zero interest, through bonds that can later convert into shares. The bet is that bitcoin will rise faster than the cost of the debt.

3. At-the-market (ATM) equity offerings. The company issues and sells new shares into the market and uses the proceeds to buy bitcoin.

Each approach scales differently. Cash is safest but slowest. Debt and new shares allow much bigger purchases but add risk, and issuing new shares can reduce the stake of existing shareholders.

The Risks

Bitcoin treasuries are not risk-free. The main concerns include:

• Volatility. Bitcoin can fall sharply, and fair-value accounting brings those swings straight into earnings.

• Debt pressure. If bitcoin falls and stays low, borrowing used to buy it can become a burden.

• Custody and security. Holding large amounts safely requires professional-grade storage.

• Liquidity and market impact. Bitcoin normally trades in deep global markets, but a company trying to liquidate a very large treasury position during stressed conditions could face slippage, reduced market depth or adverse price impact.

• Shareholder pushback. Not every investor agrees that bitcoin is a good use of company capital.

• Regulatory uncertainty. Rules are still evolving in many countries.

Another Path: Building a Treasury Through Mining

Buying bitcoin is not the only way some companies accumulate it. Public miners such as MARA, Riot and CleanSpark earn BTC by supplying computing power to the Bitcoin network and may retain part of those mining rewards on their balance sheets rather than immediately selling everything.

Mining should not, however, be described as automatically acquiring bitcoin below its market price. A miner's effective production cost depends on electricity price, machine efficiency, network difficulty, uptime, transaction fees, maintenance, financing and hardware cost. During weak mining conditions, producing one BTC can cost more than simply buying one on the market.

That is illustrated by Cassy Soriano's company-linked Medium analysis, Bitcoin Mining's Margin Problem in One Week of Data. Using one week of August 2026 data, the article estimated a median mining production cost of about $85,604 per BTC while bitcoin was around $64,900. The example shows why cheap electricity and high uptime matter, but because it covers one short period and is associated with OneMiners, it should be treated as a dated case study rather than a universal industry cost benchmark.

• For a business that specifically wants to own and operate mining hardware without building its own data center, hosted mining is another option. OneMiners provides professional hosting where customers own ASIC miners while the company handles infrastructure such as electricity, cooling, monitoring and on-site operations.

• OneMiners' published 2026 hosting rate card lists different rates depending on the site, how the machine is purchased and the length of the prepaid-energy commitment. Its lowest advertised figures—such as $0.0364/kWh in Nigeria and $0.0399/kWh in Ethiopia—are seven-year prepaid rates, not ordinary short-term power prices.

• OneMiners also offers a Crypto & Mining Tax Service for U.S. and Czech taxpayers and publishes information about equipment depreciation, including Section 179 and bonus-depreciation topics. Tax treatment depends on jurisdiction, business structure, equipment use and the rules in effect for the relevant tax year, so companies should confirm deductions with their own qualified tax adviser.

• Hosted mining can provide operational convenience, but it also introduces risks that a direct bitcoin purchase does not have: hardware depreciation, mining difficulty, downtime, repair delays, hosting contracts and long-term energy commitments. Businesses should compare the full production cost with simply purchasing bitcoin before deciding which approach fits their treasury strategy.

If still active and applicable at checkout, eligible OneMiners customers may also be able to use ONEMINERS_HOSTING_CS_25 ($25 off eligible orders of $3,000+),
ONEMINERS_HOSTING_CS_100 ($100 off eligible orders of $10,000+) or ONEMINERS_HOSTING_CS_1000 ($1,000 off eligible orders of $80,000+). Promotional terms can change, so confirm the code and eligibility before including a discount in a treasury or mining-cost model.

Thinking About a Bitcoin Treasury for Your Business?

If you run a business and are curious about holding bitcoin, keep these points in mind:

• Size the allocation around the company's actual risk capacity. Fidelity uses a hypothetical 1% allocation in one illustration to demonstrate how bitcoin might have affected a corporate treasury historically. It is a thought experiment, not a recommendation that 1% is appropriate or tolerable for every business.

• Write a policy. Strategy's published treasury policy shows the value of clear, board-approved rules on how bitcoin is bought, held and managed.

• Plan for custody. Decide early whether you will use a qualified custodian, self-custody or a mix.

• Get professional advice. Accounting, tax and legal treatment matter, so consult qualified advisers.

• Compare buying with mining carefully. A business interested in operational exposure to Bitcoin may consider mining, but it should compare projected production cost, capital requirements, hosting commitments and operational risks with the simpler alternative of purchasing bitcoin directly.

Frequently Asked Questions

Why do companies buy bitcoin? Mainly to protect against inflation, gain exposure to an asset with a fixed supply, diversify reserves and capture potential long-term growth.

Which public company owns the most bitcoin? Strategy is by far the largest corporate bitcoin holder. As of October 11, 2026, it reported 848,250 BTC. Because Strategy continues to buy bitcoin and use capital-market financing, check its latest disclosures for the current figure.

How do companies account for bitcoin? Under FASB's ASU 2023-08, U.S. companies report bitcoin at fair value, with gains and losses in net income.

Is it risky for a company to hold bitcoin? Yes. Bitcoin introduces substantial price volatility, custody risk and potentially large fair-value swings in reported earnings. Companies that borrow or issue securities to finance purchases also take on capital-structure risk. Appropriate allocation size depends on the company's liquidity needs, debt obligations, risk tolerance and business model; dedicated bitcoin treasury companies can hold extremely concentrated positions.

Can a company mine bitcoin instead of buying it? Yes. Many public miners build their treasuries this way, and hosted mining services like OneMiners let businesses do it without running their own facilities.

Final Thoughts

Companies hold bitcoin for different reasons: potential protection against currency debasement, portfolio diversification, long-term appreciation potential and strategic exposure to the Bitcoin ecosystem. Strategy demonstrated that a corporate bitcoin-treasury strategy can be executed at very large scale, while FASB's newer fair-value accounting rules removed an important reporting disadvantage that previously affected U.S. corporate holders.

The strategy still carries substantial risk. Bitcoin can experience deep drawdowns, debt-financed purchases can amplify losses, and large treasury positions can create significant earnings volatility. Businesses considering bitcoin should establish clear treasury policies, custody arrangements and risk limits and involve qualified accounting, legal and tax professionals.

Mining is a separate operational strategy rather than a guaranteed cheaper route to bitcoin. For companies that want mining exposure without operating their own facilities, OneMiners' hosting and tax resources can provide practical starting points, while the company-linked Medium analysis offers a useful mining-cost case study. Those commercial sources should be compared with live Bitcoin network data, current electricity costs and independent financial analysis before capital is committed.
