CLSK vs RIOT: How CleanSpark and Riot Platforms 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. CLSK and RIOT 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 CLSK and RIOT 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.

CleanSpark is a Las Vegas-based bitcoin mining company that operates data centers, mostly in the southeastern United States, packed with specialized ASIC machines that compete to validate bitcoin transactions and earn newly minted coins plus fees. It makes money primarily by selling some of the bitcoin it mines and by keeping the rest on its balance sheet as a treasury; reported metrics that matter most are operational hash rate (about 50 EH/s as of early 2026), cost to mine each coin (roughly $44,800 in the most recent quarter), and the size of the bitcoin stack it holds (around 13,600 BTC). Because revenue is paid in bitcoin and a chunk of the balance sheet is bitcoin, both the income statement and reported book value swing with the crypto price.

Riot Platforms is a Nasdaq-listed company whose core business is mining bitcoin: it runs large fleets of specialized computers (ASICs) that compete to validate transactions on the Bitcoin network and earn newly issued bitcoin plus fees as a reward. Riot is unusually vertically integrated for a miner, owning its Rockdale and Corsicana, Texas facilities, negotiating long-term low-cost power, and participating in Texas grid demand-response programs that pay it to curtail during peak demand. In Q1 2026 the company produced 1,473 bitcoin, down about 4% year over year, and ended the quarter with roughly 42.5 EH/s of deployed hash rate, up about 26% from a year earlier. Mining revenue was around $111.9 million, pressured by lower bitcoin prices and a roughly 24% jump in the global network hash rate that raised its average cost to mine to about $44,629 per coin (excluding depreciation).

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

• CLSK drivers: Scaled, low-cost hash rate; Cheap-power energy footprint.
• RIOT drivers: Scaling and lowering the cost of bitcoin mining; Converting spare power into AI and HPC leases.

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: CLSK carries direct bitcoin price exposure: when bitcoin falls, mining revenue and the treasury both decline, and the stock has historically moved more than bitcoin itself. For RIOT, the dominant risk is bitcoin price volatility, which drives mining profitability and the mark-to-market value of Riot's large treasury; Q1 2026's roughly $500 million net loss shows how sharply reported results can swing.

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 CLSK if you believe its drivers more; RIOT 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 CLSK and RIOT guides.

CLSK. CleanSpark's reported results are tightly correlated with the price of bitcoin: the quarter ended March 2026 showed a large net loss driven mostly by non-cash mark-to-market adjustments on its bitcoin holdings as the coin's average price fell toward the mid-$70,000s. Revenue, margins, and book value can all swing sharply quarter to quarter, so single-period figures say more about bitcoin's level than about a durable trend. These figures are approximate and tied to the asOf date; check the latest filings before relying on them.

RIOT. Figures are approximate and tied to the asOf date; verify live numbers before acting. Riot does not trade on a meaningful price-to-earnings basis because it is reported-loss-making, so investors tend to value it on hash rate, bitcoin held, and power capacity instead of earnings. The stock is highly volatile (beta around 3), with a 52-week range of roughly $10.59 to $30.32, so the figures matter most as a gauge of how much the market is pricing bitcoin upside and the AI pivot rather than current profits.

Headline figures (approximate, June 2026): CLSK shows quarterly revenue (fq2 2026) ~$136 million (down ~25% YoY), operational hash rate ~50 EH/s, bitcoin held (treasury) ~13,600 BTC, adjusted ebitda (fq2 2026) ~-$241 million; RIOT shows revenue (q1 2026 quarterly) ~$167 million (mining ~$112M, data center ~$33M), bitcoin produced (q1 2026) ~1,473 BTC, down ~4% year over year, deployed hash rate ~42.5 EH/s, up ~26% year over year, bitcoin held (treasury) ~15,680 BTC (~$1.3 billion), ~5,800 restricted.

CLSK and RIOT 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.
