Do you believe the current scale of corporate spending on AI infrastructure is financially sustainable?

IREN shares have declined 18% since September 22 after the company unveiled a $25 billion to $30 billion capital spending plan for fiscal 2027. Investors remain wary of the heavy expenditure and the impact of rising borrowing costs on large-scale infrastructure projects.

Why it matters

The capital-intensive nature of AI data centers makes financing a primary challenge, particularly as interest rates remain elevated. Market participants are scrutinizing whether IREN can sustain its expansion pace while balancing high debt costs and fluctuations in GPU rental rates.

IREN holds $4 billion in contracted annualized run-rate revenue for 2026, with three-year contracts priced above $20 million per megawatt. Meanwhile, the Ornn H100 index fell 11.1% to $2.71 per GPU-hour as of September 30.

The Tech Race

The decline in IREN shares follows a broader 11.1% drop in the Ornn H100 index, indicating a market-wide shift in the valuation of AI compute capacity. This development highlights the intensifying competition in the data center sector as firms bet billions on the future of specialized AI hardware.

Retail investors may see volatility in their portfolios as institutional analysts adjust their outlooks on IREN and similar tech infrastructure firms. For those following the broader market, the 5.34% Treasury yield serves as a benchmark for how expensive it remains to borrow capital for tech growth.

The takeaway

The sharp decline in IREN highlights how sensitive high-growth AI infrastructure companies are to both fluctuating GPU rental prices and elevated interest rates. Investors should remain mindful that capital-intensive projects require stable revenue pipelines to withstand periods of rising borrowing costs.
