"Bitcoin needs to appreciate at an annualized rate of 3.3% for capital gains to fund dividends on Strategy's Variable Rate Series A Perpetual Stretch Preferred Stock indefinitely." — Michael Saylor, Executive Chairman, Strategy Inc.
Digital Asset Treasury (DAT) companies — publicly traded firms that hold cryptocurrencies as core balance sheet assets — are facing their first structural stress test. The sector, which grew from $40 billion in aggregate market capitalization in September 2024 to approximately $150 billion by late 2025, has shed roughly half that value in the first half of 2026. Strategy (MSTR), the largest DAT by holdings, sold bitcoin for the first time under a new monetization program in late June, liquidating 3,588 BTC ($216 million) to fund preferred stock dividends. Its enterprise mNAV has dropped below 1.0, meaning the market values the company at less than the bitcoin on its balance sheet.
The problem extends beyond Strategy. Across the sector, mNAV premiums — the multiple at which DAT stocks trade relative to their underlying crypto holdings — have compressed or inverted. Some smaller DATs have suffered drawdowns exceeding 98%. The mechanism that made the model work in bull markets — issuing equity at a premium to buy more crypto — has reversed into a self-reinforcing downward spiral. Falling stock prices reduce the mNAV ratio, which limits the ability to raise capital, which limits crypto accumulation, which erodes sentiment further.
This report examines the structural dynamics of the DAT sector across Bitcoin, Ethereum, and Solana treasury strategies, the convertible debt risks accumulating on DAT balance sheets, and the divergence between passive holding models and revenue-generating approaches.
More than 200 publicly traded companies now employ variations of the DAT model across a dozen different cryptoassets, according to CoinGecko and BitcoinTreasuries.net data. Approximately 145 of those hold bitcoin specifically, with aggregate BTC holdings exceeding 1.13 million tokens as of early 2026. Several dozen additional firms hold Ethereum (over 6 million ETH, roughly 5% of circulating supply) and Solana (approximately 17.9 million SOL, roughly 2.5% of supply).
The sector raised $29 billion in capital in 2025, up from $11 billion in 2024, according to AMINA Bank research. That capital fueled aggressive accumulation strategies across the asset class spectrum.
Combined crypto holdings across all tracked DATs break down as follows, per The Block and DefiLlama dashboards: ETFs and exchanges hold approximately $107 billion, public companies $98 billion, government entities $43 billion, DeFi protocols and other structures $25 billion, and private companies $19 billion.
The concentration is stark. Strategy alone holds 843,775 BTC (approximately 4% of bitcoin's total supply) at an aggregate cost basis of $63.69 billion. Bitmine Immersion Technologies (BMNR) holds 5.77 million ETH (4.8% of circulating supply). Forward Industries leads Solana treasury allocations with 7.04 million SOL.
Strategy's shift from perpetual accumulation to active monetization marks the single most significant philosophical change in the DAT sector since the model's inception.
Between June 29 and July 5, 2026, Strategy sold 3,588 BTC for approximately $216 million under a newly approved BTC Monetization Program. The company sold 1,363 BTC at an average price of $59,256 between June 29-30, then another 2,225 BTC at $60,773 between July 1-5. Proceeds funded dividend payments across five preferred stock series — STRF, STRE, STRK, STRD, and the June monthly dividend for STRC — and replenished cash reserves to $2.55 billion from $1.4 billion.
This followed an earlier Q1 2026 sale of approximately $1.5 billion in bitcoin, used to repurchase over $1 billion in face value of 2030 and 2031 convertible notes.
Strategy's enterprise mNAV has ranged between 0.99x and 1.80x over the past year. As of mid-June 2026, it traded at approximately 0.77x by one measure — an 18% discount to the dollar value of its bitcoin reserve. Another data source pegged it at 1.07x as of mid-July. The divergence reflects methodological differences between simple reserve ratios and full enterprise-value calculations, but the direction is consistent: the premium that enabled cheap capital raising has largely evaporated.
The board's new capital management policies now allow management to sell bitcoin "whenever it believes doing so creates shareholder value." The company that built its identity on never selling has formalized a framework for doing exactly that.
Bitmine Immersion Technologies (BMNR), chaired by Fundstrat co-founder Tom Lee, represents the largest concentrated bet on Ethereum as a corporate treasury asset.
As of July 12, 2026, Bitmine reported:
The ETH treasury model offers a structural advantage over passive BTC holding: staking yield. Bitmine generates approximately $242 million in annualized staking revenue at current rates, providing recurring income that can theoretically support corporate liabilities without requiring equity issuance or asset sales.
Despite this, BMNR shares have fallen 51% in H1 2026, dropping from last year's high of $160 to approximately $15.70. The stock trades at a 2.6% discount to adjusted NAV. Three analysts covering the stock maintain a "Strong Buy" rating with a 12-month target of $34.43, implying 136% upside — a gap that underscores the market's skepticism toward the entire DAT model regardless of yield characteristics.
ETH treasury companies collectively now hold nearly 2% of all ETH, up from approximately 0.5% one month prior, according to Blockworks data. However, the total market capitalization of ETH-focused DATs ($12.7 billion) remains approximately 11% of BTC-focused DATs ($107.6 billion).
The Solana DAT ecosystem, though smaller, has grown rapidly. Publicly traded companies report a combined 17.9 million SOL held as of May 2026, per tracker data.
Forward Industries leads with 7.04 million SOL, backed by Galaxy Digital, Multicoin Capital, and Jump Crypto. Galaxy Digital manages core treasury functions including trading, lending, and staking.
Solana Company (formerly Helius Medical Technologies, ticker HSDT) acquired over 760,000 SOL with plans to deploy $335 million in additional cash reserves, backed by Pantera Capital. The former medical device company adopted a SOL-focused treasury strategy in a full corporate pivot.
Sol Strategies, a Canadian firm, has 2.8 million SOL delegated to its validators from both treasury holdings and third-party delegations.
SOL treasury companies use "SOL per share" as their north star metric — the direct analog of Strategy's "BTC per share." The structural advantage: SOL staking yields approximately 7% APY, materially higher than ETH's current rate and infinitely more than BTC's zero yield. This provides a revenue base that pure BTC DATs lack.
The DAT model's central vulnerability is its dependence on mNAV premiums to function.
When a DAT trades at, say, 2.0x mNAV, it can issue $2 of equity to buy $1 of crypto, immediately increasing its crypto-per-share ratio. This accretive dynamic drove the sector's explosive growth in 2024-2025. In reverse, the mechanics are punishing.
The sequence:
Many DATs are now trading below mNAV of 1.0, according to sector analysis from ARK Invest and others. Some smaller entrants — including Nakamoto — have suffered drawdowns exceeding 98%. ARK Invest noted in its Q2 2026 report that "DAT companies are under stress" and identified persistent ETF outflows as a major obstacle to recovery.
The self-reinforcing nature of this cycle means that passive DATs — those holding crypto without generating revenue — face existential questions about their capital structure.
The financing instruments that fueled DAT expansion are now potential liabilities.
Strategy's convertible note structure illustrates the risk profile. The company used convertible debt issuance extensively in 2024-2025 to fund bitcoin purchases. In Q1 2026, it repurchased over $1 billion in face value of its 2030 and 2031 convertibles — using bitcoin sale proceeds, not operating income. As of mid-July, it was raising $450 million in additional capital while halting bitcoin purchases.
The preferred stock layer adds recurring cash obligations. Strategy now services five preferred stock series (STRF, STRE, STRK, STRD, STRC), with STRC carrying an annualized variable dividend rate of 11.5%. These are not optional distributions — they require regular cash payments regardless of bitcoin's price trajectory.
DAT companies more broadly are turning to increasingly expensive capital sources. According to sector analysis, convertible debt and preferred stock now carry higher interest and dividend burdens than earlier financing rounds, reflecting the market's repricing of DAT credit risk.
Twenty One Capital (XXI), launched in December 2025 through a reverse merger backed by Tether and SoftBank, exemplifies the evolving structure. Tether acquired SoftBank's stake in May 2026, consolidating control. The company launched with over 42,000 BTC, making it the third-largest bitcoin treasury globally. Its model attempts to combine treasury, financial services, mining, and capital markets into a single platform — an implicit acknowledgment that passive holding alone is insufficient.
The 2026 bear market has exposed a fundamental divide in the DAT sector: companies generating revenue from their holdings versus those that merely hold.
Revenue-generating DATs:
Passive holders:
The distinction maps directly to survival probability. Revenue-generating DATs can service debt and pay dividends without selling their underlying crypto holdings. Passive DATs must either sell crypto, issue dilutive equity at a discount, or restructure — each option destructive to the model's premise.
The DAT model worked in one direction. When crypto prices rose and mNAV premiums expanded, companies could issue equity at a premium, buy crypto accretively, and drive stock prices higher — attracting more capital for more purchases. The mechanism assumed persistent or rising demand for leveraged crypto exposure through public equity wrappers.
That assumption has been tested in 2026. Bitcoin is below $65,000 after peaking above $100,000. Ethereum trades near $1,820. The mNAV premiums that justified the capital structure have largely disappeared. Strategy, the sector's archetype, now sells the asset it spent five years accumulating.
The emerging divergence between revenue-generating DATs and passive holders suggests the sector will consolidate around operating models that produce income independent of price appreciation. Bitmine's staking revenue, Sol Strategies' validator operations, and MARA's AI infrastructure pivot represent variations of this approach. Pure-play holding companies without revenue streams face a narrowing path to viability.
The DAT sector is not disappearing. Over 200 companies and $100 billion in crypto holdings represent entrenched institutional positioning. But the model is being repriced from a growth vehicle to something closer to a closed-end fund trading at a persistent discount — a familiar structure in traditional finance, and a less exciting one.
