IREN Has Microsoft and $14 Billion of Funding. Execution Is the Real Test
IREN, a Bitcoin miner turned AI cloud operator, reported $7.6B in cash, with $14B in funding capacity. Microsoft accepted its first Horizon deployment, supporting IREN's growth plans. IREN targets 300MW IT load in 2026 and 800MW in 2027, with $25B-$30B in fiscal 2027 capital spending. Hedge funds increased holdings, while short interest remains high. Microsoft's deal reduces demand risk but not construction challenges.
