Public companies now hold more than 1.1 million BTC, 6.5 million ETH, and 17.5 million SOL on their balance sheets — a combined position worth north of $100 billion at mid-June 2026 prices. The "treasury company" model pioneered by MicroStrategy (now Strategy Inc.) in 2020 has spawned at least 154 publicly traded imitators across three major chains and is reshaping corporate finance, equity capital markets, and crypto market structure simultaneously.
The template is straightforward: raise equity or convertible debt, convert proceeds to crypto, report weekly holdings, repeat. Strategy Inc. holds 846,842 BTC ($56.2 billion at $66,384 average cost). Bitmine Immersion Technologies (NYSE: BMNR) holds 5.62 million ETH ($9.7 billion at current prices), approximately 4.66% of Ethereum's circulating supply. The model has now been exported to Ethereum and Solana, introducing staking yield as a new variable that the original Bitcoin version lacked — but also amplifying capital-structure complexity with preferred equity, perpetual notes, and recurring dividend obligations that create fixed claims against inherently volatile collateral.
This report examines the economic mechanics, capital structure risks, and market-structure implications of the corporate crypto treasury phenomenon as it enters its sixth year.
The corporate crypto treasury model operates on a simple feedback loop. A public company issues equity — typically via at-the-market (ATM) offerings — or sells convertible notes. Proceeds go directly to purchasing a single crypto asset. The company reports holdings weekly, creating a public signal of conviction. If the underlying asset appreciates, the stock trades at a premium to net asset value (NAV), enabling further issuance at favorable terms. The cycle repeats.
Strategy Inc. formalized this in August 2020 when it began converting its software company's cash reserves into Bitcoin. By June 2026, the company holds 846,842 BTC at an average cost of $66,384 per coin, according to its most recent 8-K filing. Total cost basis: $33.1 billion. The stock trades at roughly 1.3–1.5x its Bitcoin NAV, a premium that funds continued accumulation.
The model's appeal is mechanical: public-market investors who cannot or will not hold crypto directly get exposure through equity. The treasury company captures the spread between its NAV premium and the cost of capital. When it works, it resembles a perpetual motion machine. When the underlying asset declines, the same mechanics operate in reverse.
As of mid-June 2026, publicly traded crypto treasury companies represent a material share of several networks' circulating supply:
| Asset | Corporate Holdings | % of Supply | Top Holder | Top Holder Share | |-------|-------------------|-------------|------------|-----------------| | BTC | ~1.13M BTC | ~5.4% | Strategy Inc. (MSTR) | 846,842 BTC | | ETH | ~6.58M ETH | ~5.5% | Bitmine (BMNR) | 5,620,754 ETH | | SOL | ~17.5M SOL | ~2.9% | Concentrated in 1 firm | ~17.5M SOL |
Between September 2025 and March 2026, ETH treasury companies increased holdings by 77%, from 3.7 million to 6.58 million tokens. BTC treasury companies grew more slowly as Bitcoin's price declined 41% from its all-time high of $124,720 in October 2025, cooling the issuance-and-buy cycle.
Beyond the top holders, a secondary tier has emerged. SharpLink Gaming (SBET) holds 872,984 ETH. The Ether Machine (ETHM) holds 496,712 ETH. Galaxy Digital (GLXY), Bit Digital (BTBT), and several smaller firms round out the ETH treasury ecosystem. On the Bitcoin side, Twenty One Capital (XXI) holds 43,500 BTC, Metaplanet (3350.T) holds 40,177 BTC, and MARA Holdings holds 35,303 BTC.
Total institutional crypto holdings — including private companies and miners — reach approximately 1.78 million BTC, or 8.5% of total supply, according to tracker data compiled by Bitcoin Mining Stock.
Bitmine Immersion Technologies illustrates how the model adapts to proof-of-stake assets. The company pivoted from hardware mining infrastructure to an Ethereum-first treasury strategy in 2025 under Chairman Tom Lee. It uplisted from NYSE American to the New York Stock Exchange on April 9, 2026, and was the 96th most-traded stock in the US by April, averaging $987 million in daily volume.
Key metrics as of June 14, 2026:
The company's stated target: own 5% of all ETH in circulation by the end of 2026. At 4.66% as of mid-June, it is within range.
On June 15, 2026, Bitmine disclosed the purchase of an additional 76,881 ETH for approximately $136 million, funded partly by a newly completed $280 million 9.50% Series A Perpetual Preferred Stock offering priced at $80 per share. The preferred stock (ticker: BMNP) carries a fixed 9.50% annual dividend, payable quarterly — a recurring cash obligation regardless of ETH price direction.
The preferred offering introduces a capital-structure dynamic absent from the original Bitcoin treasury playbook. Strategy Inc.'s primary instruments are convertible notes and ATM equity. Bitmine has layered perpetual preferred stock on top.
The annual dividend obligation on the $280 million preferred tranche alone is approximately $26.6 million. This must be paid in cash from a treasury whose primary asset — ETH — generates yield only through staking, at a variable rate. If ETH prices decline materially, the preferred dividend becomes a fixed burden against a shrinking asset base.
Strategy Inc. faces its own structural overhang. The company plans to "equitize" approximately $6 billion in convertible debt over the next three to six years, according to its filings — converting bondholders into shareholders. This avoids cash repayment but dilutes existing equity holders. The decision to equitize rather than retire debt in cash signals management's preference to preserve Bitcoin holdings over protecting per-share value.
The broader treasury company sector carries concentrated risks:
According to analysis by CCN, several treasury companies entered 2026 underwater on their holdings following Bitcoin's decline from its October 2025 peak, and "may need to sell their crypto this year to service the debt."
Bitmine's MAVAN (Made in America VAlidator Network), launched March 25, 2026, is the company's proprietary Ethereum staking platform. With 4.7 million ETH staked, MAVAN is among the largest single staking operations in the Ethereum network.
Projected annualized staking revenue: $226–$269 million, depending on the week's yield rate (ranging from 2.79% to 2.83% on a 7-day basis, per the company's disclosures). At the higher end, projected revenue reaches $289 million when full staking deployment is achieved.
The staking yield is real but comes with caveats:
The treasury company model has measurable effects on crypto market structure:
Supply absorption. With 154+ public companies holding 5.4% of BTC supply and a similar share of ETH, a meaningful fraction of circulating tokens is locked in corporate treasuries with stated long-term holding intent. This reduces effective float and can amplify price movements in both directions.
Equity-crypto correlation. Treasury company stocks function as leveraged crypto proxies. BMNR's equity moves in tight correlation with ETH spot price, amplified by the NAV premium/discount mechanism. Strategy's stock similarly tracks BTC. This creates a transmission channel between equity markets and crypto markets that did not exist five years ago.
Capital formation channel. ATM offerings and convertible debt from treasury companies represent a significant source of net new capital flowing into crypto. When Strategy issues $500 million in equity, that capital flows from equity investors to Bitcoin — a pipeline that bypasses traditional crypto on-ramps entirely.
Index and ETF implications. As treasury companies grow in market cap — BMNR at ~$10 billion, Strategy at multiples of that — they become candidates for index inclusion, which drives passive fund buying of shares that are, at bottom, wrappers around crypto holdings. The line between a crypto ETF and a treasury company stock blurs.
The corporate crypto treasury model has scaled from a single company's experiment to a $100 billion-plus phenomenon touching three major networks in under six years. The ETH variant, led by Bitmine, adds staking yield as a genuine economic input — but also introduces perpetual preferred obligations and validator concentration risk that the Bitcoin version does not carry.
The fundamental question is whether the NAV premium that powers the model is durable or cyclical. If crypto enters a sustained downturn, treasury companies face a structural challenge: fixed obligations against declining, volatile collateral, with dilutive issuance as the primary relief valve. The same feedback loop that drives accumulation in rising markets can drive forced selling in falling ones.
For now, the model persists because the NAV premium persists. According to tracker data, MSTR trades at 1.3–1.5x Bitcoin NAV, and BMNR trades at comparable multiples of its ETH holdings. As long as public-market investors are willing to pay more than $1 for $1 of crypto exposure, the issuance machine keeps running.
The data does not yet show a reckoning. It shows a model that has scaled faster than the market's ability to price its tail risks.
