The five largest cloud providers are spending on AI infrastructure faster than they generate cash, and trends suggest their free cash flow could turn negative around Q3 2026.

What happened: Infrastructure spending at Microsoft, Amazon, Alphabet, Meta, and Oracle is growing at about 70 percent a year, while operating cash flow is only rising at roughly 23 percent. If these trends hold, spending will overtake cash flow around Q3 2026, according to analysis by Epoch AI based on SEC filings.

Why it matters: These companies remain profitable and hold large cash reserves (except Oracle), so they are not in immediate financial distress. However, free cash flow—the money left after subtracting capital spending from operating revenue—could hit zero or turn negative if the trend continues. Alphabet has already raised $85 billion（約14兆円） in equity, and Amazon and Nvidia have sold bonds to raise additional cash, suggesting they are preparing for tighter cash positions.

What to watch: Epoch AI cautions that these are simple extrapolations. The key question, whether AI investments will eventually drive enough revenue to close the gap, is not factored into the projection.
