IREN Rallies 23% as AI Cloud Revenue Jumps 687%

Shares of IREN jumped 23% after the company reported that AI cloud revenue surged 687% over the past year, shifting investor attention away from its original Bitcoin mining business, according to GuruFocus.

IREN, a company that built its name on Bitcoin mining, has been repriced by the market as something else: an operator of AI compute capacity. Shares jumped 23% after the company's AI cloud revenue was reported to have surged 687% over the past year, a growth rate large enough to change which line of the income statement investors are watching.

That figure, reported by GuruFocus, is the whole story in one number. A 687% increase means the AI cloud line is now several multiples of what it was a year earlier. For a business whose earnings power was historically a leveraged bet on the Bitcoin price and on the cost of electricity, that is a structural shift in what the equity represents.

What the tape showed going into the move

IREN last traded at 44.70, up 7.32% from a prior close of 41.65, as of the close on Friday, Sept. 4, 2026. The shares finished that session at 44.70 against a day range of 41.00 to 44.75 — within 0.05 of the session high, the kind of close that suggests buyers were still paying up at the bell rather than fading the move. Market data provided for the stock does not specify the listing currency or exchange, so the price is quoted as reported.

The context matters. That same session was a mixed one for the broad market: the S&P 500 tracker (SPY) closed at $770.23, down 0.38%, and the Dow 30 tracker (DIA) closed at $534.12, down 0.52%, while the Nasdaq 100 tracker (QQQ) closed at $719.00, up 0.19%. In other words, the index that carries the AI complex was the only one of the three to finish higher, and IREN's gain came in a tape where the average large-cap stock was falling. A single-stock move of that size against a soft benchmark is company-specific news, not beta.

Why a mining business gets a different multiple when it sells compute

Bitcoin miners and AI cloud providers use overlapping physical assets — land, grid interconnects, substations, cooling, racks — but they sell fundamentally different products, and the market pays for them differently.

• Mining revenue is uncontracted. A miner sells nothing to a customer; it produces a commodity whose price it cannot influence, and its margin is the spread between the Bitcoin price and its all-in power and hardware cost. Revenue visibility is close to zero beyond the current hashprice.
• AI cloud revenue is typically contracted. Compute is sold to identifiable customers, often on multi-period terms, which converts an unpredictable commodity stream into something closer to a utility or a hosting business with a forward book.

That distinction is why growth in the AI line can move a stock more than the same dollar of mining revenue would. Contracted revenue supports a higher multiple because it is more forecastable, and because it is less correlated with the crypto cycle that has historically dictated when these companies could raise capital.

It also changes the capital story. A miner competes for power and land with everyone else chasing block rewards. A company selling AI compute competes for the same power and land against hyperscalers and data-center developers with far deeper balance sheets — but it can also sign customers who will fund or underwrite capacity ahead of construction. The asset base looks similar; the funding logic does not.

The gap between the 23% headline and the last close

Investors reading this should be precise about two separate numbers. The 23% jump is the move reported alongside the AI cloud disclosure. The most recent verified session for the stock — the Sept. 4 close — showed a 7.32% advance to 44.70 from 41.65, a gain of 3.05 on the day. Those are not the same event, and the more recent market data available here does not capture the full 23% repricing described in the report.

What that means practically: anyone sizing a position off the headline percentage should check the live quote rather than assume the last close reflects it. Fast-moving, retail-heavy names in the crypto-and-AI overlap routinely give back part of a one-day gain, and just as routinely extend it.

What has to show up next for the re-rating to stick

A 687% growth rate is arithmetically easiest to produce off a small base. The relevant question is not whether AI cloud grew fast — it plainly did — but how large the line has become in absolute terms relative to mining, and whether the growth is contracted or spot.

Four things will determine whether the AI narrative holds:

• Revenue mix. The share of total revenue coming from AI cloud versus mining, and the direction of that share quarter to quarter. Until AI is the larger line, the stock still carries Bitcoin-price risk.
• Contract duration and counterparties. Committed capacity with named customers on multi-year terms is worth far more to a valuation than short-term GPU rental.
• Powered capacity delivered. Energized megawatts, not announced megawatts. The bottleneck in AI data centers is grid connection and transformers, not intent.
• Margin per megawatt. Whether compute sold at contracted rates earns more per unit of power than mining the same power would, net of the far higher capital cost of AI-grade hardware.

The broader pattern is now familiar across the sector: companies that assembled cheap power and permitted sites for mining discovered those assets were scarce inputs for AI training and inference, and have been converting them. IREN's 687% AI cloud growth is one of the more emphatic data points that the conversion produces revenue, not just press releases. The unresolved part is how much of the company's earnings power it accounts for — and that is a mix question the next set of financials, not the share price, will answer.

Frequently asked questions

Why did IREN shares jump?

The move followed the disclosure that IREN's AI cloud revenue surged 687% over the past year. That growth rate shifted investor focus away from the company's original Bitcoin mining operation and toward its compute business, and the shares jumped 23% as reported by GuruFocus.

What was IREN's most recent share price?

IREN last traded at 44.70, up 7.32% from a prior close of 41.65, as of the market close on Friday, Sept. 4, 2026. The day range was 41.00 to 44.75, meaning the stock finished within 0.05 of its session high. The market data supplied does not specify the listing currency.

Is IREN still a Bitcoin mining company?

IREN was historically known mainly for Bitcoin mining, and mining remains part of the business. What has changed is the growth profile: AI cloud revenue rose 687% over the past year. Until disclosed financials show AI as the larger revenue line, the equity still carries exposure to the Bitcoin price.

Why does AI revenue get valued more highly than mining revenue?

Mining revenue is uncontracted — the company produces a commodity at whatever price the market sets, with almost no forward visibility. AI cloud revenue is typically sold to identifiable customers under term contracts, which makes it more forecastable. Markets generally pay a higher multiple for contracted, recurring revenue than for commodity output.

How did the wider market perform on the same day?

On Sept. 4, 2026, the S&P 500 tracker SPY closed at $770.23, down 0.38%, and the Dow 30 tracker DIA closed at $534.12, down 0.52%. The Nasdaq 100 tracker QQQ closed at $719.00, up 0.19%. IREN's gain therefore came against a broadly weaker large-cap tape.

What should investors watch next in IREN's numbers?

Four items matter most: the split of total revenue between AI cloud and mining, the duration and counterparties behind AI contracts, energized rather than announced data-center capacity, and margin per megawatt for compute versus mining. A 687% growth rate off a small base still leaves the absolute mix unresolved.
