CRWV vs IREN: Which Is the Better Buy in 2026?

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.

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. CRWV and IREN 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 CRWV and IREN 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.

CoreWeave is a specialized cloud computing company, often called a neocloud, that builds and operates data centers packed with Nvidia GPUs and rents that compute capacity to companies that train and run artificial-intelligence models. Founded in 2017 (originally as a crypto-mining operation before pivoting to AI infrastructure) and led by chief executive and co-founder Michael Intrator, it operates over 250,000 Nvidia GPUs across dozens of data centers and roughly 3.5 gigawatts of contracted power. Unlike general-purpose clouds, CoreWeave is engineered specifically for AI workloads, offering dense GPU clusters, high-speed networking, and a managed software layer branded as CoreWeave Cloud. Its customers include Microsoft, OpenAI, Meta, Nvidia itself, and other large AI labs.

IREN Limited operates data centers powered largely by renewable energy across Texas in the United States and British Columbia in Canada. Historically its money came almost entirely from bitcoin mining, running large fleets of specialized machines that earn bitcoin in exchange for securing the network, with profitability tied to bitcoin's price, mining difficulty, and the company's low electricity costs. More recently it has built an AI cloud business that rents out NVIDIA GPUs for machine learning and large language model workloads, and it is converting several former mining facilities into AI and high-performance computing capacity. In its fiscal third quarter of 2026 the company reported total revenue of about $144.8 million, split between roughly $111.2 million of mining revenue and about $33.6 million of fast-growing AI cloud revenue.

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

• CRWV drivers: Explosive revenue growth and backlog; Privileged Nvidia relationship.
• IREN drivers: Owned, renewable-powered sites; AI and HPC cloud pivot.

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: The risks here are unusually large and structural. For IREN, iREN still earns most of its revenue from bitcoin mining, so a lower bitcoin price, rising difficulty, or the post-halving economics can pressure results, as seen in a sharp sequential mining revenue decline.

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 CRWV if you believe its drivers more; IREN 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 CRWV and IREN guides.

CRWV. Figures are approximate and tied to the asOf date; verify live numbers before acting. CoreWeave does not trade on earnings because it is deeply unprofitable, so investors watch revenue growth, backlog, adjusted EBITDA, capital expenditure, and debt instead. The valuation embeds enormous future growth from that backlog, which means the stock can swing violently on any change in AI-demand sentiment, guidance, or financing conditions.

IREN. IREN's reported earnings are distorted by large noncash items tied to decommissioning mining hardware, so headline net loss overstates the cash picture relative to adjusted EBITDA. The market values it far more on its AI cloud pipeline, NVIDIA contract, and power portfolio than on trailing mining results, which makes traditional multiples like P/E volatile and often not meaningful. All figures are approximate, move sharply with bitcoin prices and the AI buildout, and should be verified against current filings before relying on them.

Headline figures (approximate, July 2026): CRWV shows revenue (ttm) ~$6.2 billion, more than doubling year over year, revenue (q1 2026) ~$2.08 billion, up from ~$982 million a year earlier, 2026 revenue guidance ~$12 billion to $13 billion, net loss (q1 2026) ~$740 million (adjusted EBITDA ~$1.2 billion); IREN shows quarterly revenue (fiscal q3 2026) ~$144.8 million total (~$111.2M mining, ~$33.6M AI cloud), adjusted ebitda (fiscal q3 2026) ~$59.5 million, net loss (fiscal q3 2026) ~$247.8 million, driven largely by noncash impairments, cash ~$2.6 billion as of April 30, 2026.

CRWV and IREN 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 CRWV and IREN exposure against your real portfolio. It is not an investment adviser.
