Is MARA a Buy? What to Consider in 2026
Short answer
The bull case for MARA Holdings (MARA) rests on Leveraged bitcoin exposure: MARA's revenue, treasury value, and reported earnings all move with the price of bitcoin, often more sharply than the coin itself. Revenue (FY2025) is ~$907M. If you believe that thesis holds, the real questions become position sizing and overlap, not timing. The main risk to that view: MARA is one of the more volatile large-cap ways to hold bitcoin exposure, and its share price can fall far faster than the coin during downturns. Whether MARA is a buy comes down to whether you believe the thesis. This is informational, not a recommendation, and Walnut is not an investment adviser.
MARA Holdings, formerly Marathon Digital, is a vertically integrated bitcoin mining and digital-energy company headquartered in Florida. It runs a large fleet of mining data centers (roughly 1.9 GW of power capacity across 18 sites as of the end of 2025) and produced about 8,799 bitcoin during 2025 at an energized hashrate that reached roughly 72 EH/s by early 2026. The company also holds a large bitcoin treasury, lends some of its coins to third parties for interest income, and has begun diversifying into AI-inference compute and hyperscaler data-center capacity through moves like its majority stake in Exaion and a partnership with Starwood Capital. The investment picture is dominated by bitcoin. Revenue rose to roughly $907 million in 2025, but that growth tracks the price of bitcoin far more than operational efficiency, and quarterly results swing violently with crypto markdowns. In Q1 2026 revenue fell about 18% year over year to ~$174.6 million and the company reported a net loss of ~$1.26 billion, driven largely by a roughly $1.0 billion negative fair-value change on its bitcoin holdings and receivables when the coin price dropped during the quarter. That makes MARA a high-volatility name whose reported earnings are heavily influenced by mark-to-market accounting on its treasury rather than mining cash flow alone.
What's the case for buying MARA?
1. Leveraged bitcoin exposure
MARA's revenue, treasury value, and reported earnings all move with the price of bitcoin, often more sharply than the coin itself. When bitcoin rises the mining margin and treasury markup can compound; when it falls both mining economics and the balance sheet compress at once.
2. Scale and hashrate growth
MARA is among the largest miners by energized hashrate, which reached roughly 72 EH/s in early 2026, up about 33% year over year. Greater scale can lower unit mining costs and defend share of network rewards, though it also raises the electricity and hardware bill.
3. Energy and AI-compute diversification
Management is repositioning MARA as a digital-energy and infrastructure company, monetizing power capacity through AI-inference compute, data-center partnerships (Starwood), and a majority stake in Exaion. The aim is revenue that is less tied to bitcoin's daily price, though these efforts are early and unproven at scale.
4. Bitcoin treasury and lending
MARA holds a large bitcoin treasury and earns interest by lending some coins to third parties (around $32 million of interest income in 2025). In 2026 the company began selling bitcoin selectively to fund operations, a shift from its prior long-term hold-only stance.
What are the risks to MARA?
MARA is one of the more volatile large-cap ways to hold bitcoin exposure, and its share price can fall far faster than the coin during downturns. Reported earnings are heavily distorted by fair-value swings on its treasury, so a single quarter can show a billion-dollar loss driven by accounting rather than cash burn. Mining economics face pressure from rising network difficulty, the post-halving reduction in block rewards, and high electricity and equipment costs. The company has raised capital through convertible debt and equity, which can dilute shareholders, and its newer energy and AI-compute ventures may not scale as hoped. Regulatory and tax treatment of bitcoin mining also remains uncertain.
How is MARA valued? (as of JULY 2026)
Snapshot for MARA as of July 2026, sourced from Yahoo Finance and may be delayed. Valuation figures move with price and earnings; verify the current numbers with your broker before deciding.
- Revenue (FY2025): ~$907M
- Revenue (Q1 2026): ~$174.6M (-18% YoY)
- Net loss (Q1 2026): ~$1.26B (fair-value driven)
- Bitcoin produced (FY2025): ~8,799 BTC
- Energized hashrate: ~72 EH/s (early 2026)
- Bitcoin treasury: ~35,000-54,000 BTC (falling on sales)
MARA's headline financials are dominated by bitcoin. Revenue growth in recent years tracks the coin's price rather than operating leverage, and the large Q1 2026 net loss came mostly from mark-to-market declines on its bitcoin holdings and receivables. Treasury size has been shrinking through 2026 as the company shifted to selling coins for operating flexibility.
How do you decide if MARA is a buy?
Rather than asking whether MARA is a buy in the abstract, it tends to help to answer four questions:
- Thesis: do you believe the case above, and is it still true today?
- Time horizon: a single stock can be volatile, so a longer horizon absorbs more of the swings.
- Position sizing: a thesis can be right and the sizing still wrong; decide how much of your portfolio one name should be.
- Overlap: check whether you already hold MARA indirectly through an index or sector ETF before adding more.
