IREN, one of the largest publicly traded Bitcoin miners by hashrate, reported that AI cloud revenue reached $70.5 million in its fiscal fourth quarter, edging past Bitcoin mining revenue of $66.7 million for the first time. The crossover, disclosed in IREN's FY26 results filed with the U.S. Securities and Exchange Commission, marks a structural shift for a company built on proof-of-work.
The gap between the two segments was $3.8 million, a thin margin that nonetheless reverses the historic ordering of IREN's business. AI cloud, the segment that leases GPU compute for artificial-intelligence workloads, became the company's larger revenue line. IREN retains a large Bitcoin mining fleet, making the milestone a rebalancing rather than an exit from mining.
The two revenue streams rest on different economics. Bitcoin mining revenue depends on hashrate, network difficulty, and the BTC price, while AI cloud revenue is contract-driven compute leasing insulated from difficulty adjustments. IREN expanded into GPU hosting after securing Nvidia partner status and scaling its GPU capacity, infrastructure that now underpins the larger segment.
The result illustrates broader pressure on Bitcoin miners: the same low-cost power and data-center footprint that make mining viable also make AI hosting attractive, especially as mining costs rise after the halving amid AI power demand. IREN's numbers put a concrete figure on that pivot. Still, the market reaction was not uniformly positive: IREN shares fell roughly 8% after the report, indicating investors are weighing how to value the changing revenue mix.
For the Bitcoin network, the relevance is indirect but real. If miners diversify revenue toward AI compute, they gain a buffer against difficulty-driven margin compression, which can keep hashrate online during periods when block rewards alone would not justify electricity costs. IREN's disclosure is a single data point in that structural trend.
