Why S&P doubts Meta's AI spending can pay for itself

S&P Global Ratings revised its outlook on Meta Platforms to negative from stable on Friday, Oct. 30, 2026, citing significant uncertainty around capital spending and free operating cash flow. The credit rating itself was affirmed at AA-. Only the outlook changed.

The move lands as Meta prepares to ask public markets for $97.5 billion in stock to fund its AI buildout. Last week, the company forecast annual capital expenditure between $135 billion and $145 billion, after reporting a free cash flow deficit of $2.12 billion in the third quarter.

S&P questioned Meta's ability to monetize its AI investments relative to peers also spending heavily on data center buildouts and going cash flow negative. That comparison matters. The AI boom has pushed Big Tech capital expenditure to levels that have stoked investor concerns about whether the sector can generate returns quickly enough. S&P's action gives those concerns a concrete ratings dimension.

A negative outlook is not a downgrade. It is a warning that if Meta's AI spending keeps outpacing cash generation, its credit profile could weaken. That would raise borrowing costs and pressure a stock sale timed to fund the buildout. The rating remains investment grade at AA-, but the direction of travel is now flagged.

The timing is notable. Meta is not just spending heavily; it is planning to raise capital from public markets while doing so. S&P's outlook revision turns an abstract debate about AI capital expenditure sustainability into a financing question with a date attached.

The next data point will be the stock sale itself.
