IREN LtdRising Treasury yields raise debt costs for IREN's buildout, pressuring the stock despite strong AI capacity sales.
IREN Limited shares fell 4% to $35.58, and Cipher Mining dropped 6% to $14.56, as a backup in long-term Treasury yields reversed Monday's gains across Bitcoin mining and AI infrastructure stocks. The 10-year Treasury yield climbed to 4.78%, raising the cost of the next tranche of debt these capital-hungry miners need to finance their buildouts. The CoinShares Bitcoin Mining and Digital Power ETF (WGMI) declined 4% to $41.14, while the Global X Data Center & Digital Infrastructure ETF (DTCR) retreated just 1% to $27.50, showing rate pressure hits miners harder than the broader data-center category. IREN's management said 2026 AI capacity is largely sold out with about $4 billion of contracted annualized run-rate revenue, and the company delivered the first of four 50-megawatt liquid-cooled deployments for Microsoft in August. Short interest in IREN stands at 27% of float, and H.C. Wainwright reiterated a Buy rating with a $90 price target, suggesting the stock could snap back sharply on any yield retreat.
