APLD 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. APLD 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 APLD 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.

Applied Digital designs, builds, and operates data centers for artificial intelligence, high-performance computing, and related workloads. It makes money primarily by leasing critical IT capacity (measured in megawatts of power) to compute customers under long-term contracts, plus a legacy data-center hosting segment. The economics resemble those of a specialized real-estate or infrastructure landlord: the company spends heavily up front to secure power, land, and buildings, then earns recurring rent over multi-year lease terms. Its flagship Polaris Forge 1 campus in Ellendale, North Dakota is engineered to scale up to roughly a gigawatt over time, with a second campus broken ground more recently.

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.

• APLD drivers: Anchor CoreWeave leases create long-dated contracted revenue; Power and site pipeline in a supportive jurisdiction.
• 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 model is extraordinarily capital-intensive: building gigawatt-scale capacity requires continuous debt and equity financing, and Applied Digital has carried billions in debt while pricing large senior secured note offerings to fund expansion, which raises interest costs and dilution or leverage risk. 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 APLD 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 APLD and IREN guides.

APLD. Applied Digital is still reporting net losses while it builds capacity, so traditional earnings multiples do not apply cleanly and much of the story sits in the contracted backlog rather than current profit. Figures are approximate and tied to the asOf date; revenue, losses, debt, and market cap move with each financing, lease, and earnings update. Investors generally weigh the long-dated lease backlog against the heavy ongoing capex and financing needed to deliver it.

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, 2026-06-27): APLD shows revenue (trailing 12 months) ~$319 million, most recent quarter revenue ~$127 million (up ~139% year over year), net loss (most recent quarter, to common) ~$101 million (~$0.36 per share), contracted lease backlog Reported in the tens of billions; CoreWeave expanded to full 400MW at Polaris Forge 1; 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.

APLD 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.
