COIN vs MARA: How Coinbase and MARA Holdings Compare (2026)

Same yardstick, side by side (as of July 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.

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. COIN 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 COIN 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. Walnut is not an investment adviser.

Coinbase (COIN) is the largest US-based cryptocurrency exchange. It lets retail and institutional customers buy, sell, store, and stake crypto assets, and it earns most of its money from transaction fees on that trading activity. Beyond the consumer exchange, Coinbase runs Coinbase Prime for institutions, a custody business, a USDC stablecoin partnership with Circle that generates interest income, and subscription and services revenue including staking and Coinbase One. It has expanded into derivatives, an international exchange, and Base, its own layer-2 blockchain. Founded in 2012 and headquartered in the US, Coinbase went public in 2021 and is widely treated as a regulated, publicly traded proxy for crypto adoption. Its results are highly sensitive to crypto prices and trading volumes, which makes revenue swing sharply between bull and bear markets.

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.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• COIN drivers: Regulated crypto on-ramp; Subscription and services growth.
• MARA drivers: Leveraged bitcoin exposure; Scale and hashrate growth.

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: Coinbase remains highly dependent on crypto prices and trading volumes; a prolonged bear market can sharply cut transaction revenue. 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.

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 COIN 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 COIN and MARA guides.

COIN. Coinbase's valuation is difficult to anchor with a normal multiple because earnings swing dramatically with crypto prices and volume. The stock often trades on sentiment toward crypto adoption rather than trailing fundamentals. Bull markets can produce very high profits and a low apparent multiple, while bear markets can flip the company to losses. Figures are approximate and move sharply; verify current numbers before relying on them.

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, early 2026): COIN shows revenue (ttm) ~$6 billion (varies widely with crypto cycle), transaction revenue share ~half of total, highly cyclical, subscription and services revenue ~$2 to 3 billion run rate, more recurring, net income swings between large profits and losses by cycle; 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.

COIN 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.
