The former Bitcoin miner has been re-rated around AI infrastructure, with July contract wins, bullish analyst calls and neocloud momentum helping drive a volatile run.
IREN Limited closed at $39.75 on Monday, August 3, up $2.95 or 8.02%, before adding 1.36% in overnight trading on the Blue Ocean ATS (after-hours trading venue) to $40.29 shortly after 01:00 AM EDT, according to Yahoo Finance data. The move did not follow a single confirmed company announcement tied specifically to Monday’s gain, but instead extended a momentum-driven rally as investors continue to re-rate the company from a Bitcoin miner toward an AI cloud infrastructure play. A key recent catalyst came on July 20, when IREN announced $2.8 billion in new multi-year customer contracts and raised its 2026 annualized revenue run-rate target to above $4 billion, with roughly 85% of that goal under contract. The company, formerly Iris Energy, still mines Bitcoin but has increasingly shifted its power-heavy data centers toward AI workloads and now describes itself as a vertically integrated AI cloud provider. Investor enthusiasm has also been supported by bullish analyst commentary and a broader rally in neocloud stocks, companies that rent out GPU computing power for AI. At the same time, the stock remains highly risky because its expansion plans are capital-intensive, its valuation depends heavily on future AI demand and execution, and its trading has been marked by sharp swings, high short interest and continued exposure to Bitcoin mining economics. Investors are now watching the August 27 earnings report for more clarity on AI cloud revenue growth and expansion funding.
