Second top US Bitcoin miner authorizes sale of entire BTC stash as MARA eyes $3.8 billion liquidity option
MARA Holdings could also be poised to check the present BTC treasury meta. Major miners have been accumulating BTC as a strategic treasury quite than treating it as working capital. A shift may have implications that reach nicely past a single firm.
The firm’s March 2 submitting authorizes balance-sheet gross sales of its entire 53,822 BTC treasury, representing an entire reversal of its 2024 “retain all mined and bought Bitcoin for the foreseeable future” coverage.
Bitcoin trades round $68,000, down almost 46% from late-2025 highs, whereas market depth has thinned to ranges the place modest promoting creates an outsized influence.
The timing raises a query: what occurs when one of the business’s largest holders treats Bitcoin as working capital quite than as a matter of conviction?
The coverage that wasn’t supposed to alter
MARA’s 2024 10-Ok positioned it alongside Strategy as a Bitcoin maximalist.
The pivot started in late 2025, when MARA sold roughly 4,076 BTC for $413.1 million, at an implied common of $101,000 per BTC. The 2026 submitting permits balance sheet sales, making Bitcoin “a readily convertible supply of liquidity.”
Three elements sharpen the stakes.
First, 15,315 BTC are loaned or pledged as collateral, representing 28% of holdings. That leaves 38,507 BTC unrestricted: $2.6 billion or 60 days of post-halving issuance.
Second, MARA recorded a $422.2 million fair-value decline in 2025 and a $69.1 million buying and selling loss.
Third, MARA partnered with Starwood Capital to develop AI knowledge facilities focusing on 1 GW, with a path past 2.5 GW, a capital-intensive infrastructure that pulls liquidity wants ahead.
The logic: fund operations and AI by promoting BTC as a substitute of diluting shareholders. The trade-off transforms MARA from a Bitcoin ETF right into a capital allocator holding unstable property.
The timing is not random
Regarding “why now?”, three drivers converge.
First, steadiness sheet stress. Post-halving, rewards had been minimize to three.125 BTC, whereas issue and vitality prices squeezed margins.
Output fell 7% to eight,799 BTC regardless of rising hashrate to 66.4 EH/s. When Bitcoin drops from the $76,000 to $126,000 vary to $60,000, liquidity turns into pressing.
The firm faces $350 million in convertible notes maturing in 2027.
Second, AI capex. MARA’s Starwood partnership targets websites toggling between Bitcoin mining and AI compute. Starwood leads design and building; MARA contributes websites and retains as much as 50% possession.
This bets power-to-compute monetization beats post-halving mining returns.
Third, market microstructure. Liquidity has deteriorated since late 2025, with spot volumes working 25% to 30% under year-ago ranges. MARA, as a discretionary vendor, does not must crash markets. Instead, it creates an overhang narrative when sentiment is fragile.
MARA formalized this not regardless of weak situations, however as a result of weak situations make BTC gross sales credible versus costlier funding.
The overhang is not simply MARA
Public miners collectively maintain 116,697 BTC, down 4.42% month over month.
MARA’s 53,822 BTC represents almost half of the entire. The broader pool consists of Riot Platforms (18,005 BTC), CleanSpark (13,513 BTC), Hut 8 (10,278 BTC), and Core Scientific (2,537 BTC).
Core Scientific expects to monetize “considerably all” holdings in 2026. In January, it offered 1,900 BTC for $175 million at $92,000 per coin. Bitdeer liquidated its entire treasury in late February.
Miners now deal with Bitcoin as stock to monetize when AI infrastructure economics beat hash-rate growth.
The query is how shortly and at what scale others will comply with, and three situations body the vary.
In the conservative state of affairs, miners promote manufacturing, however preserve treasuries intact. A ten% non-MARA drawdown equals 6,287 BTC or 14 days of issuance.
In a average case, miners fund AI capex by promoting 5% to 10% of their holdings. For MARA, that is 2,700 BTC to five,400 BTC, or 6 to 12 days of issuance. This is equal to $180 million to $361 million.
A 25% collective drawdown releases 29,174 BTC, or 65 days of issuance.
In the aggressive state of affairs, a 50% drawdown would put 58,349 BTC into markets, equal to 130 days of new provide. The threat is narrative, not quantity.
Bitcoin’s 24-hour quantity exceeds $50 billion, however when a number of miners grow to be identified sellers throughout macro stress, influence runs via sentiment and derivatives positioning quite than spot prints.
MARA’s submitting permits others to comply with with out showing distressed.
| Scenario | Who sells | BTC quantity | Est. notional worth (at ~$68k) | “Days of new issuance” equal (at ~450 BTC/day) |
|---|---|---|---|---|
| Conservative | Non-MARA miners (10% drawdown) | 6,287 BTC | ~$428M | ~14 days |
| Moderate (MARA) | MARA sells 5–10% of holdings | 2,700–5,400 BTC | ~$184M–$367M | ~6–12 days |
| Moderate (business) | Public miners collective (25% drawdown) | 29,174 BTC | ~$2.0B | ~65 days |
| Aggressive | Public miners collective (50% drawdown) | 58,349 BTC | ~$4.0B | ~130 days |
What the shift reveals
On top of the three situations, three competing narratives emerge.
The first is the AI pivot: miners repurpose energy infrastructure into knowledge facilities, utilizing Bitcoin as gasoline to fund them.
MARA’s Starwood partnership targets AI-capable infrastructure with toggle economics. This is a strategic reallocation, consisting of energy certainty to capability certainty.
The second narrative is the tactical threat administration: after $422.2 million in fair-value declines and $69.1 million in buying and selling losses, MARA treats Bitcoin as a managed place.
Thin depth and macro sensitivity enhance the worth of discretionary liquidity instruments.
The final narrative is a structural regime shift: the top of miner HODL. The distinction between 2024’s “retain all BTC” and 2026’s “could purchase or promote infrequently” indicators that miners behave like capital allocators, optimizing returns throughout mining, grid providers, and AI leases.
Each narrative carries totally different provide implications.
If an AI pivot occurs, the BTC gross sales fund transitions. In this case, provide stress is front-loaded however finite.
In case the danger administration narrative is the one shifting ahead, gross sales observe volatility, making miners countercyclical sellers.
Lastly, a regime shift would imply that the roughly 117,000 BTC miner treasury turns into topic to energetic administration, altering baseline assumptions about provide absorption.
The clock that issues
The subsequent readability window is MARA’s 10-Q type for the primary quarter, projected mid-May.
Investors will scrutinize how a lot BTC was monetized post-policy change, whether or not AI milestones tie to treasury drawdowns, and what steering on minimal reserves or promote cadence is offered.
The hole till May creates a story vacuum that macro situations will fill.
Bitcoin trades in risk-off form, pushed by vitality shocks and inflation fears, precisely when “who could be compelled to promote” dominates.
MARA’s submitting does not say it’ll promote a majority. Still, authorization alone creates price-sensitive reference when liquidity is skinny sufficient that the execution technique determines whether or not a $1 billion sale is absorbed quietly or amplifies draw back.
Starwood’s timeline provides urgency. The partnership targets 1 GW near-term, with a path to 2.5 GW, however “near-term” is undefined.
If MARA accelerates building to seize AI demand, funding wants compress. If slower buildouts, BTC gross sales could stretch over years. That determines whether or not MARA’s treasury turns into a multi-year drag or a one-time recapitalization.
If the first-quarter earnings reveal a number of miners increasing sale authorizations or linking BTC monetization to AI capex, markets will reprice the entire miner treasury base as provide overhang quite than strategic reserve.
That repricing does not require precise promoting, it simply means traders cease treating miner holdings as locked provide.
What’s truly at stake
MARA’s shift issues much less for what it permits than what it indicators.
For 4 years, miners positioned treasuries as differentiators by aligning fairness efficiency with BTC appreciation. That labored when Bitcoin rallied, capital was low-cost, and post-halving economics had been theoretical.
Now Bitcoin trades almost 50% off highs, capital markets favor AI over crypto, and post-halving margins are tighter than modeled.
If MARA executes AI pivots efficiently and makes use of BTC gross sales as one-time funding, the treasury drawdown story ends cleanly. If AI initiatives drag on or Bitcoin recovers quicker than anticipated, miners could have offered reserves at cyclical lows to fund underperforming initiatives.
For crypto markets, stakes are clear.
Miner treasuries had been among the many final bastions of non-speculative Bitcoin demand, representing entities that collected Bitcoin for operational functions.
If that cohort shifts to energetic administration, Bitcoin loses a structural bid and good points a structural vendor. When the world’s largest Bitcoin miner by holdings formalizes its potential to promote its entire stack, it is a sign that even believers are hedging.
