In 2026, the crypto asset market is undergoing a profound transformation in its holding structure. Once dominated by retail investors and early tech enthusiasts, Bitcoin and Ethereum are now being systematically absorbed onto the balance sheets of publicly traded companies. In mid-April 2026, both Strategy (formerly MicroStrategy) and Bitmine Immersion Technologies simultaneously announced record-breaking updates to their holdings: Strategy purchased 34,164 Bitcoins in a single week for $2.54 billion, bringing its total holdings to 815,061 BTC and officially surpassing BlackRock’s iShares Bitcoin Trust (IBIT) as the world’s largest single Bitcoin holder. Bitmine, meanwhile, acquired 101,627 Ethereum in one week, raising its total ETH holdings to approximately 4,976,000, which accounts for about 4.12% of Ethereum’s circulating supply. These figures are not isolated events; they signal that corporate treasury allocations to crypto assets have evolved from "experimental exploration" to a capital allocation paradigm with structural impact.
Major Accumulations: Strategy and Bitmine Set New Holding Records
On April 20, 2026, Strategy filed an 8-K with the U.S. Securities and Exchange Commission (SEC), revealing that between April 13 and 19, it purchased 34,164 Bitcoins at a total cost of roughly $2.54 billion, averaging about $74,395 per coin. This marks the third largest single-dollar purchase in the company’s history. Following this acquisition, Strategy’s total Bitcoin holdings reached 815,061 BTC, with a cumulative investment of approximately $61.56 billion and an average cost of $75,527 per coin.
Almost simultaneously, Bitmine Immersion Technologies announced that as of April 19, the company held 4,976,485 Ethereum, having purchased 101,627 ETH in the previous week—worth about $230 million and setting the largest weekly accumulation record for 2026. The company’s combined crypto assets, cash, and strategic investments total around $12.9 billion. Of its ETH holdings, 3,334,637 coins are staked, accounting for about 67% of its total holdings, generating an annualized staking yield of approximately $221 million and a 7-day annualized yield of 2.88%.
According to Gate market data, as of April 23, 2026, Bitcoin was priced at $77,966, with a 24-hour trading volume of about $512 million, a market cap of roughly $1.49 trillion, and a market dominance of 56.37%. Ethereum was priced at $2,350.53, with a 24-hour trading volume of about $329 million, a market cap of $275.69 billion, and a market share of 10.41%.
The Race for Holdings: Timeline of Surpassing BlackRock IBIT
The competition between Strategy and BlackRock’s IBIT for Bitcoin holdings has been a months-long structural shift. At the end of 2025, Strategy held about 672,500 BTC, while IBIT held around 773,990 BTC—a gap of roughly 100,000 coins. Entering 2026, Strategy accelerated its accumulation pace: in Q1, it added between 89,599 and 94,470 BTC, an increase equivalent to about 40% of its total additions for all of 2025, marking the second-largest quarterly acquisition in the company’s history.
By mid-March, Strategy’s holdings reached about 761,068 BTC, narrowing the gap with IBIT’s 782,170 BTC to roughly 21,102 coins. On April 2, the gap shrank further to around 16,000 coins. Between April 6 and 12, Strategy acquired 13,927 BTC for about $1 billion, bringing its total to 780,897 BTC, with the gap holding at about 10,000 coins. Ultimately, the acquisition of 34,164 BTC between April 13 and 19 allowed Strategy to overtake IBIT.
Bitmine’s Ethereum accumulation followed a different timeline. From 2024 to 2025, as Bitcoin’s halving effects became apparent and global energy policies tightened, traditional crypto mining profitability continued to shrink. Against this backdrop, Bitmine began redirecting part of its cash flow and financing proceeds into Ethereum. In the second half of 2025, as spot Ethereum ETFs stabilized in trading volume and assets under management across major financial markets, Bitmine accelerated its on-chain accumulation and expanded its ETH exposure through convertible bond issuance.
Holdings Overview: Comparing Scale, Cost, and Structure of Three Major Entities
Below are the core data publicly disclosed between April 19 and 22, 2026:
| Entity | Asset Type | Holdings | Total Cost | Average Cost | % of Circulating Supply |
|---|---|---|---|---|---|
| Strategy | Bitcoin | 815,061 BTC | ~$61.56 billion | $75,527/coin | ~3.88% |
| BlackRock IBIT | Bitcoin | ~802,823 BTC | N/A (ETF flows at market price) | Investors avg. ~$89,000/coin | ~3.82% |
| Bitmine | Ethereum | ~4,976,485 ETH | Not fully disclosed | Not disclosed | ~4.12% |
Source: Strategy SEC Form 8-K, Bitmine official announcements, public on-chain data
These figures reveal several key structural features:
First, Strategy’s holdings now account for 3.88% of Bitcoin’s circulating supply, surpassing BlackRock IBIT’s 3.82%. Together, the two entities control about 7.7% of Bitcoin’s circulating supply. This means that for every 13 tradable Bitcoins, one is held by these two institutions.
Second, comparing accumulation speeds, Strategy added roughly 142,500 BTC from the start of 2026 to date, while IBIT added about 28,800 BTC in the same period—Strategy’s pace is nearly seven times faster.
Third, Bitmine’s Ethereum holdings represent 4.12% of circulating supply, with 3,334,637 ETH staked, accounting for about 2.76% of circulating supply. This staking scale means that about 2.76% of Ethereum’s tradable "float" is locked in the consensus layer, unavailable for secondary market trading.
Model Analysis: Three Distinct Corporate Holding Logics—Treasury, ETF, and Mining Company
Analyzing Strategy, BlackRock IBIT, and Bitmine side by side may seem like a comparison of "holding quantities," but in essence, these are fundamentally different vehicles for crypto asset exposure. The following table compares them across four dimensions: capital nature, income source, governance structure, and risk exposure.
| Dimension | Strategy | BlackRock IBIT | Bitmine |
|---|---|---|---|
| Capital Nature | Active fundraising (equity, convertible bonds) | Passive aggregation (investor flows) | Mining cash flow + convertible bond financing |
| Income Source | Bitcoin price appreciation + BTC yield | Management fees (~0.25%) | ETH price appreciation + staking yield |
| Governance Structure | Single company board decisions | ETF issuer/custodian separation | Single company board decisions |
| Core Risk | Leverage financing cost erosion | Scale volatility from investor flows | ETH price decline + staking yield reduction |
| Auxiliary Yield | None (pure holding) | None | Annualized staking yield ~$221 million |

Of Strategy’s $2.54 billion purchase, about 85% came from perpetual preferred stock STRC issuance (net proceeds $2.176 billion), with the remainder from MSTR common stock issuance (net proceeds $366 million). Bitmine, meanwhile, generates about $221 million in annualized yield from staking ETH, with a 7-day annualized yield of 2.88%.
Strategy’s accumulation is essentially a financial engineering play—converting equity market premium into Bitcoin holdings. Its sustainability depends on two conditions: the market premium ratio for MSTR stock (mNAV) remains above 1, and Bitcoin’s price does not stay below average holding cost for extended periods. Bitmine’s staking model provides structural cushioning—regardless of ETH price fluctuations, staking yield generates positive cash flow, offering significant defensive value during asset price downturns.
Market Narratives: Three Mainstream Interpretations in Public Discourse
Discussions around Strategy surpassing IBIT and Bitmine’s large-scale Ethereum accumulation have crystallized into three mainstream narrative frameworks:
Corporate Treasuries Replacing ETFs as the Main Incremental Buyers of Crypto Assets
Some market participants argue that Strategy’s accumulation pace—seven times that of IBIT—shows that public companies are replacing ETFs as the primary institutional demand source for crypto assets. In Q1 2026, corporate treasuries collectively added about 62,000 BTC, with Strategy contributing the vast majority.
This narrative is supported by data, but it’s important to note that ETF holdings are driven by investor flows, which may contract during market downturns, while corporate treasury purchases are more autonomous and persistent. The relationship is not simply "replacement"—they represent parallel channels with different capital characteristics.
Bitmine’s Staking Model Offers Public Companies a New Paradigm for ‘Productive Crypto Asset Holding’
Supporters highlight that Bitmine stakes 67% of its ETH holdings, generating annualized yield of about $221 million. This model addresses the traditional corporate pain point of "zero yield" on crypto holdings. In a cycle of declining fiat interest rates, staking yields of 3%-4% are close to or slightly below the yield on U.S. 10-year Treasuries, but combined with ETH’s potential price appreciation, they offer an asymmetric return structure.
The certainty of staking yield depends on the continued operation of the Ethereum network, but ETH price volatility far exceeds Treasury principal volatility. Changes in fair value of crypto assets on corporate financial statements may completely offset staking yield. The core value of this model is providing cash flow cushioning, not replacing price risk.
Institutional Concentration Risk Is Accumulating
Some market participants express concerns: Strategy and IBIT together hold about 7.7% of Bitcoin’s circulating supply, Bitmine holds about 4.12% of Ethereum’s supply. If this concentration increases further, it could trigger liquidity crises under extreme market conditions.
This concern is reasonable. However, from another perspective, the long-term holding tendency of corporate treasuries actually reduces tradable supply in the secondary market, which may support prices if demand remains stable. Concentration is a "double-edged sword"—its impact depends on holder behavior.
Industry Ripples: Effects on Supply-Demand, Capital Products, and Network Governance
Impact on Crypto Asset Supply-Demand Structure
As of early 2026, public companies’ total Bitcoin holdings surpassed 1.03 million coins, accounting for about 5.2% of circulating supply. The latest accumulations by Strategy and Bitmine have further increased this percentage.
Corporate treasury buying is reshaping market supply and demand in two ways. First, supply-side freezing: public companies tend to hold long-term rather than trade short-term, so acquired crypto assets "disappear" from the market, reducing tradable supply. Second, demand-side signaling: accumulation by leading public companies serves as a reference for others, potentially triggering imitation.
Impact on Capital Market Product Structure
Strategy’s mNAV premium was nearly 1x at the start of 2026, indicating the market was no longer willing to pay a substantial premium over its Bitcoin holdings. At the same time, the company is increasingly reliant on preferred stock financing, with STRC’s annual coupon rate reaching 11.5%.
The evolution of Strategy’s financing structure reveals a key constraint for corporate crypto treasury strategies—when stock price premiums fade, equity-financed crypto accumulation faces cost pressures. This may drive more companies toward assets with ongoing cash flow (like staked ETH) or other financing tools.
Impact on Ethereum Network Security and Governance
Bitmine has staked about 3,334,637 ETH, roughly 2.76% of Ethereum’s circulating supply.
A single entity controlling such a large staking share does not technically threaten network security (since validator power is distributed across many nodes), but it introduces new considerations at the governance level. When corporate staking reaches 3%-5% of circulating supply, their practical influence in Ethereum improvement proposal discussions and community decisions increases—not through formal voting rights, but via economic weight.
Conclusion
The wave of corporate crypto treasury expansion in April 2026 marks a shift in institutional participation—from "indirect holding via ETFs" to "direct holding in corporate treasuries." Strategy’s 815,061 BTC surpasses BlackRock IBIT, Bitmine’s 4,976,000 ETH approaches the critical 5% threshold of circulating supply—these milestones reveal a structural trend: publicly traded companies are becoming direct, indispensable participants in crypto asset networks.
From a data perspective, ongoing corporate treasury accumulation reduces tradable supply in the secondary market, potentially providing structural price support if demand remains steady. From a model perspective, Strategy’s leveraged accumulation and Bitmine’s staking yield represent two distinct risk-return structures, offering different benchmarks for future entrants. From a risk perspective, rising holding concentration, financing cost pressures, and crypto asset price volatility’s impact on corporate financial statements form the "three major challenges" for corporate crypto treasury strategies.
The market is now in the "second phase" of the corporate crypto treasury wave: early adopters have proven the strategy’s feasibility (despite severe stress tests in Q1 2026), but large-scale replication and sustainability remain to be tested by the market and time. For participants tracking this trend, core indicators include: the evolution of Strategy’s financing tools and costs, Bitmine’s staking scale and yield changes, and whether more mid-sized public companies follow the lead of industry giants into this space.
