Is IREN a Buy? What to Consider in 2026
Short answer
The bull case for IREN (IREN) rests on Owned, renewable-powered sites: IREN controls land, grid connections, and predominantly renewable power across Texas and British Columbia, with a power portfolio it describes as 5GW+. Quarterly revenue (fiscal Q3 2026) is ~$144.8 million total (~$111.2M mining, ~$33.6M AI cloud). If you believe that thesis holds, the real questions become position sizing and overlap, not timing. The main risk to that view: 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. Whether IREN is a buy comes down to whether you believe the thesis. This is informational, not a recommendation, and Walnut is not an investment adviser.
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. The company was founded in 2018 by brothers Daniel and Will Roberts in Australia and went public on the Nasdaq in November 2021 as Iris Energy, built from the start around clean, predominantly hydroelectric power under long-term agreements. It rebranded to IREN Limited in November 2024 as it broadened beyond bitcoin into AI infrastructure. The defining shift came as it secured a $3.4 billion, five-year AI cloud contract with NVIDIA, with NVIDIA also making an investment that vests as GPUs are deployed across IREN campuses. IREN is targeting hundreds of megawatts of AI cloud capacity and roughly 150,000 GPUs by the end of calendar 2026, using only a small fraction of its larger multi-gigawatt power portfolio.
What's the case for buying IREN?
1. Owned, renewable-powered sites.
IREN controls land, grid connections, and predominantly renewable power across Texas and British Columbia, with a power portfolio it describes as 5GW+. Low-cost electricity and owned infrastructure are the scarce inputs for both bitcoin mining and AI compute. Bringing forward energization of its large West Texas substation expands the capacity it can monetize.
2. AI and HPC cloud pivot.
AI cloud revenue grew sharply on a sequential basis, reaching about $33.6 million in fiscal Q3 2026, as IREN rents NVIDIA GPUs for AI training and inference. A $3.4 billion five-year NVIDIA cloud contract anchors the buildout, and the company has pointed to billions of dollars of annual recurring revenue under contract as the mix shifts toward AI.
3. Self-funded growth from mining cash flow.
Bitcoin mining, while shrinking as a share of the business, still generates revenue and cash that can help fund the AI transition alongside outside financing. IREN exited fiscal Q3 2026 with roughly $2.6 billion of cash, giving it a buffer to fund GPU purchases and data center construction during the phased pivot.
4. Optionality on a large power pipeline.
Management has said its near-term AI targets use only about 10 percent of its multi-gigawatt power portfolio. That leaves substantial headroom to add AI capacity, additional contracts, or other compute demand over time without needing to secure entirely new sites, which is the hardest and slowest part of the buildout.
What are the risks to 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. The AI pivot is capital intensive and carries execution risk: deploying tens of thousands of GPUs, energizing substations, and converting mining halls on schedule are all hard, and delays or cost overruns would hurt. The company has reported large net losses driven partly by noncash impairments from decommissioning mining hardware, and funding the buildout may involve further debt or equity that can dilute holders. Competition for AI compute and power is intense, from other miners-turned-HPC operators and from much larger, better-capitalized cloud providers.
How is IREN valued? (as of June 2026 (fiscal Q3 2026 results, quarter ended April 30, 2026))
- 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
- Power portfolio: ~5GW+; near-term AI targets use ~10% of it
- Market cap: ~$17 to 24 billion through June 2026 (highly variable)
- Dividend: none
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.
How do you decide if IREN is a buy?
Rather than asking whether IREN is a buy in the abstract, it tends to help to answer four questions:
- Thesis: do you believe the case above, and is it still true today?
- Time horizon: a single stock can be volatile, so a longer horizon absorbs more of the swings.
- Position sizing: a thesis can be right and the sizing still wrong; decide how much of your portfolio one name should be.
- Overlap: check whether you already hold IREN indirectly through an index or sector ETF before adding more.

The bottom line on IREN
The bottom line: IREN's story right now is Owned, renewable-powered sites, with quarterly revenue (fiscal q3 2026) at ~$144.8 million total (~$111.2M mining, ~$33.6M AI cloud). If you believe that narrative continues, the call is about sizing IREN sensibly and checking overlap with what you own; if you doubt it (the risk: 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.), it is not for you. Decide from the thesis, not the ticker. Walnut is not an investment adviser.

What does IREN do?
+
IREN Limited, formerly Iris Energy, operates renewable-powered data centers in Texas and British Columbia. It historically earned most of its money from bitcoin mining and is now building an AI cloud and high-performance computing business that rents out NVIDIA GPUs. It is converting former mining facilities into AI capacity, backed by a multibillion-dollar NVIDIA cloud contract and a large power portfolio.
Is IREN a bitcoin or AI stock?
+
Both, in transition. IREN still generates the majority of its revenue from bitcoin mining, about $111 million in its fiscal Q3 2026 quarter, but its fast-growing AI cloud business and roughly 5GW+ power portfolio are why many investors now treat it as an AI infrastructure story. The market increasingly values it on the AI pivot while bitcoin exposure remains a real near-term factor.
What is IREN's ticker symbol?
+
IREN, listed on the Nasdaq. The company was founded in 2018 as Iris Energy by brothers Daniel and Will Roberts, went public in November 2021, and rebranded to IREN Limited in November 2024. It trades during US market hours and is available at every major US brokerage as whole or fractional shares.
How does IREN make money?
+
Today most revenue comes from bitcoin mining, where IREN runs specialized machines that earn bitcoin, with profits tied to bitcoin's price and its low electricity costs. A growing and higher-margin slice comes from AI cloud services, renting NVIDIA GPUs for AI training and inference. The strategy is to shift the mix toward AI cloud over time using its existing power-rich sites.
