CIFR vs MARA: Which Is the Better Buy in 2026?
Last updated August 2026
Short answer
CIFR is the larger of the two ($9.13B market cap): the incumbent the market prices for continued execution (43.13x forward earnings, beta 3.20). MARA is the smaller challenger ($4.32B), priced similarly on forward earnings (-16.65x): more room to run, but more to prove. The real question is which set of drivers you believe, and whether owning one (or both) leaves you over-concentrated.
CIFR vs MARA: the tie-breaker metrics
Same yardstick, side by side (as of August 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.
| Metric | CIFR | MARA | What it tells you |
|---|---|---|---|
| Market cap | $9.13B | $4.32B | Size. The larger name is the incumbent; the smaller has more room to grow and more to prove. |
| Forward P/E | 43.13 | -16.65 | Valuation on next year's expected earnings, the same yardstick for both. Lower is cheaper for that growth; higher means the market is paying up. |
| Beta | 3.20 | 5.37 | Volatility vs the market. Above 1 swings harder than the index; below 1 is steadier. Higher beta means bigger drawdowns to hold through. |
| Price vs 52-week range | 69% of range | 28% of range | Where today's price sits between the 52-week low and high. Near the high is momentum with less margin of safety; near the low is out of favor or a discount, depending on why. |
| Price / book | 12.67 | 1.93 | How much you pay over book value. Very high can signal an asset-light, high-return business or a rich price. |
Before you buy: how CIFR and MARA affect your concentration
The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. CIFR and MARA share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.
This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined CIFR and MARA exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

What does Cipher Mining (CIFR) do?
Cipher Mining (now operating under the name Cipher Digital, ticker CIFR) is a US-based company that builds and runs industrial-scale data centers in Texas, originally to mine Bitcoin. Its self-mining business earns revenue by running specialized computers that secure the Bitcoin network and are rewarded in BTC, which the company either sells for cash or holds on its balance sheet. The economics depend on the Bitcoin price, the global network hash rate (which dilutes each miner's share of rewards), the periodic halving of block rewards, and above all the cost of electricity, where Cipher has historically been among the lowest-cost miners in the industry. Its main sites include Odessa, Black Pearl, and Barber Lake.
What does MARA Holdings (MARA) do?
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.
CIFR vs MARA: how do they differ?
Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.
- CIFR drivers: AI and HPC hosting pivot; Low-cost power and Texas land position.
- MARA drivers: Leveraged bitcoin exposure; Scale and hashrate growth.
Which fits which kind of investor
A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: Cipher is a speculative, high-volatility name exposed to several large risks at once. For 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.
CIFR or MARA: which should you pick?
Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick CIFR if you believe its drivers more; MARA if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the CIFR and MARA guides.
CIFR vs MARA: the full fundamentals
CIFR. A Bitcoin-miner-turned-AI-infrastructure hybrid like Cipher does not read like a normal company. Mining revenue is a function of BTC price, network hash rate, and the halving, so it can swing wildly quarter to quarter, and reported net income is often dominated by non-cash items such as mark-to-market on its Bitcoin and convertible notes plus impairments, which can produce huge GAAP losses even when operations are progressing. The forward story sits in the contracted HPC backlog, which is a multi-year revenue pipeline rather than current sales, so investors weigh capacity (megawatts), contract length, tenant credit quality, and the capital needed to build the sites. Useful lenses include EH/s and cost-to-mine for the mining side, contracted MW and dollars of backlog for the AI side, and the balance of debt and share count being used to fund it all.
MARA. 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.
Headline figures (approximate, FY2025 results and Q1 FY2026 business update): CIFR shows fy2025 revenue ~$168.5M (incl. ~$16.9M from HPC), bitcoin mined (q3 2025) ~629 BTC at ~$114,000 avg, self-mining hash rate ~23.6 EH/s (Q3 2025), bitcoin held ~1,166 BTC (~$125M, late 2025); MARA shows 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.
The bottom line: CIFR vs MARA
CIFR and MARA are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme. Walnut can show your combined CIFR and MARA exposure against your real portfolio. It is not an investment adviser.

FAQ
What is the difference between CIFR and MARA?
+
Cipher Mining (now operating under the name Cipher Digital, ticker CIFR) is a US-based company that builds and runs industrial-scale data centers in Texas, originally to mine Bitcoin. MARA Holdings, formerly Marathon Digital, is a vertically integrated bitcoin mining and digital-energy company headquartered in Florida. They show up together because they share investment themes, but they are different businesses, so the better fit depends on which thesis you are expressing.
Is CIFR or MARA the better stock?
+
Neither is universally better. CIFR is the larger incumbent; MARA is the smaller challenger and looks cheaper on forward earnings. Walnut is informational, not investment advice. Compare what each does, the tie-breaker metrics above, and the risks, then decide which fits your thesis and what you already own.
Which is cheaper, CIFR or MARA?
+
On forward P/E (as of August 2026), CIFR trades at 43.13x and MARA at -16.65x, so MARA is the cheaper of the two on next year's expected earnings. A lower multiple is not automatically the better buy: a richer valuation can be justified by faster growth, and a lower one can reflect real risk. Weigh the multiple against how fast each business is compounding.
Should you own both CIFR and MARA?
+
Because they share themes, owning both concentrates you in that theme. That can be intentional (a focused bet) or accidental (less diversification than it looks). Walnut can show your combined exposure across both, and whether adding either over-concentrates you, before you buy.
What are the risks of CIFR vs MARA?
+
CIFR: Cipher is a speculative, high-volatility name exposed to several large risks at once. Its mining revenue rises and falls with the Bitcoin price, the network hash rate, and the post-halving block reward, while rising power costs can compress margins quickly. The AI pivot carries heavy execution risk: signed leases are only worth their headline value once the data centers are actually built, energized, and operating, and timelines (Barber Lake completion targeted around late 2026) can slip. Funding the build-out requires large amounts of debt and equity, so dilution and leverage are ongoing concerns, and the company reported a sizable GAAP net loss in Q4 2025 driven by non-cash mark-to-market and transition-related impairments. Counterparty concentration (a large share of contracted revenue tied to Fluidstack, with Google as backstop) and broader competition for power, chips, and tenants add further uncertainty. 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.
