"We are not going to stop. We are going to buy more bitcoin." — Michael Saylor, Executive Chairman, Strategy Inc., March 2026
Corporate cryptocurrency treasury activity has collapsed to its narrowest participation since the model emerged in 2020. According to CryptoQuant data published March 27, non-Strategy bitcoin treasury companies purchased a combined 1,000 BTC over the prior 30 days — a 99% decline from the August 2025 peak of 69,000 BTC. Strategy alone acquired approximately 45,000 BTC in the same window, representing 98% of all corporate bitcoin buying.
On the Ethereum side, a parallel concentration is forming. BitMine Immersion Technologies (BMNR) purchased 71,179 ETH the week of March 24-30, 2026 — its largest weekly acquisition of the year — lifting its holdings to 4.732 million tokens, roughly 3.92% of ETH's total supply. With Strategy breaking its 13-week bitcoin buying streak on March 29 and MARA Holdings selling 15,133 BTC to retire $1 billion in debt, the corporate crypto treasury sector is undergoing structural realignment. Two firms — Strategy for BTC, BitMine for ETH — now account for the vast majority of net corporate accumulation across both major assets.
Strategy Inc. (NASDAQ: MSTR) holds 762,099 BTC as of March 29, 2026, acquired at an aggregate cost of $57.69 billion and an average price of $75,694 per coin, according to the company's public disclosures. At bitcoin's current price of approximately $67,800, the position carries unrealized losses of roughly $6 billion.
The top five publicly traded bitcoin treasury companies by holdings:
| Rank | Company | Ticker | BTC Held | Approx. Value | |------|---------|--------|----------|---------------| | 1 | Strategy Inc. | MSTR | 762,099 | $51.7B | | 2 | Twenty One Capital | XXI | 43,514 | $2.95B | | 3 | MARA Holdings | MARA | 38,689 | $2.62B | | 4 | Metaplanet | 3350.T | 35,102 | $2.38B | | 5 | Galaxy Digital | GLXY | 25,723 | $1.74B |
Strategy's 762,099 BTC represent over 3.6% of bitcoin's fixed 21 million supply and approximately 76% of all bitcoin held by publicly listed treasury companies. The concentration has increased over Q1 2026 as competitors reduced or halted acquisitions.
On March 29, Strategy broke its 13-week consecutive buying streak. Executive Chairman Michael Saylor did not post his customary Sunday "Orange Dot" purchase signal on X. Instead, the company highlighted its perpetual preferred equity offering, Stretch (STRC). CEO Phong Le announced in February that the company plans to transition from common stock issuance to preferred shares for future bitcoin funding, a structural shift in its capital-raising mechanism.
BitMine Immersion Technologies (OTC: BMNR) — originally a bitcoin mining firm — has positioned itself as the dominant Ethereum treasury company. As of March 30, 2026, the company holds 4.732 million ETH, approximately 3.92% of Ethereum's total supply. Total crypto and cash holdings stand at $10.7 billion, according to a company press release filed via PR Newswire.
The company's 71,179 ETH purchase during the week of March 24-30, valued at approximately $143 million at ETH's price near $2,025, marked its largest weekly acquisition of 2026. BitMine has accelerated ETH purchases for four consecutive weeks during a period when broader treasury buying has stalled.
The top five publicly traded Ethereum treasury companies:
| Rank | Company | Ticker | ETH Held | Approx. Value | |------|---------|--------|----------|---------------| | 1 | BitMine Immersion | BMNR | 4,732,000 | $9.6B | | 2 | SharpLink Gaming | SBET | 869,154 | $1.76B | | 3 | The Ether Machine | — | 498,600 | $1.01B | | 4 | Forum (fmr. ETHZilla) | — | 61,650 | $125M | | 5 | BTCS | BTCS | — | — |
According to CoinGecko, 30 institutions collectively hold 6,662,417 ETH worth approximately $13.8 billion, representing 5.52% of Ethereum's total supply. BitMine alone accounts for 71% of that institutional total.
The number of active corporate bitcoin buyers has dropped from 54 companies in August 2025 to 13 in March 2026, per CryptoQuant data. Of the 119 publicly traded companies that hold bitcoin on their balance sheets, the vast majority made no net purchases in Q1 2026.
Several factors explain the retreat:
Price drawdown. Bitcoin traded above $110,000 in mid-2025. At approximately $67,800 as of March 30, 2026, the asset has declined roughly 38% from that peak. Many treasury companies that purchased near the top are underwater. ETH has followed a similar trajectory, falling from nearly $5,000 in August 2025 to approximately $2,025 — a 60% drawdown.
Balance sheet constraints. Companies that used convertible notes or at-the-market equity issuance to fund purchases face tighter capital conditions. Rising yields and equity dilution concerns have limited further issuance for smaller treasury firms.
Capital reallocation to AI. Several former bitcoin treasury and mining companies have redirected capital toward artificial intelligence infrastructure. MARA's pivot is the most visible example, but the pattern extends across the mining sector, as documented in prior reporting on miners signing $70 billion in AI hosting contracts.
Regulatory uncertainty. The CLARITY Act's proposed yield ban on stablecoins and ongoing SEC enforcement actions have created caution around expanded crypto exposure for public companies.
MARA Holdings' decision to sell 15,133 BTC between March 4 and March 25, 2026, at an average price of approximately $65,300 per coin, marks a definitive break from the "HODL" strategy that defined the company. The $1.1 billion in proceeds funded the repurchase of zero-interest convertible senior notes due in 2030 and 2031.
The sale dropped MARA from second to third place among publicly traded bitcoin holders, behind Twenty One Capital (XXI), which now holds 43,514 BTC. MARA's updated 2026 treasury policy explicitly permits monetization of balance-sheet bitcoin for liquidity needs — a policy that did not exist six months ago.
MARA shares rose 10% on the announcement, according to CoinDesk, suggesting the market valued debt reduction over bitcoin accumulation. The move reflects a broader shift: the corporate treasury model, once pitched as a pure bitcoin exposure vehicle, is evolving into a more conventional capital allocation framework where crypto is one asset among several.
The two dominant treasury accumulators share structural similarities but diverge in asset selection and capital structure.
| Metric | Strategy (BTC) | BitMine (ETH) | |--------|---------------|---------------| | Primary Asset | Bitcoin | Ethereum | | Holdings | 762,099 BTC | 4,732,000 ETH | | % of Asset Supply | 3.6% | 3.92% | | Total Position Value | ~$51.7B | ~$9.6B | | Avg. Acquisition Cost | $75,694/BTC | Not disclosed | | Unrealized P&L | ~-$6B | Not disclosed | | Debt Outstanding | ~$8.2B conv. notes | Not disclosed | | Funding Mechanism | ATM equity + conv. notes + preferred | Equity issuance | | Share of Corp. Holdings | 76% of all listed BTC | 71% of all listed ETH |
Both companies have built positions exceeding 3.5% of their respective asset's total supply. Both face concentration risk: a forced liquidation by either firm would represent a supply shock to the underlying asset's market.
Strategy's $8.2 billion in convertible debt creates a distinct risk profile. The notes carry maturities extending into the 2028-2030 window, and the company's ability to service these obligations depends on bitcoin remaining above its cost basis or on continued equity issuance capacity. At current prices, Strategy's bitcoin is worth approximately $6 billion less than its total acquisition cost.
BitMine's position is less transparent. The company's total crypto and cash holdings of $10.7 billion include $961 million in cash and equity stakes (including $102 million in Eightco Holdings) alongside 197 BTC, but its debt structure and cost basis for ETH acquisitions are not detailed in available public filings.
The consolidation of corporate crypto buying into two firms raises several structural concerns.
Liquidity risk. Strategy's 762,099 BTC represent approximately 11 days of bitcoin's average daily spot volume. BitMine's 4.732 million ETH represent a larger share of Ethereum's daily volume. Any material liquidation event — whether voluntary or forced — would create significant price impact.
Narrative fragility. The corporate treasury model was promoted as evidence of broad institutional adoption. In practice, it has consolidated into a near-duopoly. Of the 119 public companies holding bitcoin, one company holds 76% of the aggregate position. This concentration undermines the thesis that diverse corporate demand provides a structural price floor.
Counterparty dependency. Both Strategy and BitMine fund purchases through equity issuance. Sustained share price declines could limit further issuance, creating a feedback loop: lower crypto prices reduce treasury values, depressing share prices, constraining capital raises, and halting further purchases.
The emerging ETH treasury model. BitMine's accumulation of 3.92% of ETH supply has occurred with minimal market attention relative to Strategy's bitcoin purchases. The Ethereum treasury model remains underdeveloped — only 36 publicly traded companies hold ETH compared to 119 holding BTC — but BitMine's concentration is proportionally higher than Strategy's.
Metaplanet, the fourth-largest bitcoin treasury company with 35,102 BTC, represents a notable exception to the pullback trend. The Japan-listed firm raised ¥40.8 billion ($255 million) in March 2026 through a share placement and plans to continue accumulating toward a 210,000 BTC target. However, its monthly purchase volume remains a fraction of Strategy's pace.
The corporate crypto treasury model has entered a consolidation phase that inverts its original premise. What began as a distributed institutional adoption strategy — dozens of companies adding bitcoin and ether to their balance sheets — has narrowed to two firms conducting the vast majority of net buying. Strategy holds 76% of all publicly listed corporate bitcoin; BitMine holds 71% of all publicly listed corporate ether.
The remaining 117 bitcoin-holding companies and 29 ether-holding institutions are, for the most part, holding existing positions without adding to them. Several are actively liquidating. The model has not failed in aggregate — combined corporate crypto holdings across all assets exceed $70 billion — but the buying activity that sustains and grows those positions has concentrated to a degree that introduces single-entity risk to what was designed as a market-wide strategy.
Whether this consolidation is temporary — a function of price drawdowns and tight capital markets — or structural depends on two variables: the trajectory of crypto prices through Q2 2026, and whether Strategy and BitMine can sustain their respective equity issuance programs at current valuations. The data, as of March 31, 2026, suggests the broader corporate treasury thesis is being tested by the same market conditions it was meant to hedge against.
