The $145 Billion Question Hanging Over the AI Boom
Strong sales are no longer enough
The sharpest message from financial markets this week came from a company whose underlying business is still growing rapidly. Meta reported third-quarter revenue growth of 26% to $64.6 billion, yet its shares fell 7% on Thursday. Investors were looking beyond sales towards the increasingly expensive task of turning artificial intelligence investment into cash.
Meta generated $32.79 billion in operating cash flow during the quarter, but substantial infrastructure spending left it with negative free cash flow of $2.12 billion, compared with positive free cash flow of $10.63 billion a year earlier. The company also narrowed its forecast for full-year capital expenditure to $135 billion–$145 billion, raising the lower end by $5 billion.
There is an important qualification. Meta's reported operating margin halved to 20%, but its results included a $9.89 billion legal charge unrelated to AI investment. Excluding that charge, operating profit would have been $22.88 billion. With $82.45 billion in cash, equivalents and marketable securities, the company is hardly facing an immediate funding crisis.
What unsettled investors was the direction of travel. Meta announced a new non-voting share class, initially to be distributed through a stock dividend in 2027, giving it greater flexibility to raise equity later. The dividend itself does not dilute existing shareholders' proportional economic ownership. Subsequent issuance to outside investors could.
By yesterday's close, the NAS100 had fallen 3.1%, its steepest decline since June, while the Philadelphia Semiconductor Index plunged 6.7%. Nvidia lost 4%, and AI infrastructure companies suffered further losses. The SPX500 declined 1.23%, although the US30 edged higher, suggesting investors were rotating away from technology rather than abandoning equities wholesale.
Oil and bonds complicate the calculation
The week had started on a more reassuring note. On Tuesday, easing oil prices and Treasury yields helped the US30 gain 1.21%, while investors assessed early corporate results. Wednesday's technology rebound then gave way to Thursday's selling as Meta's numbers forced a closer examination of capital requirements.
The macroeconomic setting made that scrutiny harder to dismiss.
UKOil crude jumped 2.88% on Thursday to settle at $112.89 a barrel, its highest close since May, after Houthi attacks in Saudi Arabia renewed fears of regional supply disruption. Energy prices at these levels threaten transport costs, corporate margins and inflation expectations, leaving central banks less room to reduce borrowing costs.
US initial unemployment claims also fell to 194,000 in the week ending 17 October, suggesting layoffs remain limited. That resilience gives the Federal Reserve reason to remain cautious about inflation, even as investors grow concerned about expensive financing and its effect on investment.
Yet Treasury yields fell sharply on Thursday. The 10-year yield dropped approximately 19 basis points to 4.953%, its largest daily decline since March 2023, as investors sought safety from falling equities. This reflected growing concerns about economic growth rather than evidence that inflation had suddenly ceased to matter.
Europe supplied another warning about financing conditions. French 10-year borrowing costs rose above 5%, with the premium over German bonds approaching 180 basis points amid fiscal concerns and political uncertainty. The pressure was spreading to other indebted European economies, illustrating how investors increasingly distinguish between borrowers according to their perceived financial resilience.
The next phase will be judged in cash
The AI investment thesis is not disproved by one difficult quarter. Meta's advertising business remains powerful, and management says better recommendations and monetisation are already generating additional revenue. Its substantial liquidity also provides room to sustain investment while new products develop.
But market expectations are changing. Chip orders and data-centre construction measure activity. Returns on invested capital determine whether that activity ultimately creates shareholder value.
For smaller infrastructure providers relying heavily on debt, the distinction is particularly important. Rising credit spreads or difficulties refinancing existing obligations could force slower expansion long before demand for computing power disappears.
Over the next 6-24 months, investors should watch whether AI-related revenues grow sufficiently to offset depreciation, energy bills, financing costs and capital expenditure. They should also monitor whether major technology companies increasingly turn to equity markets to fund projects previously expected to be financed internally.
The wider economy will influence that calculation. A sustained retreat in oil could relieve inflation and funding pressures. Further supply disruptions could have the opposite effect, particularly while sovereign borrowing costs remain elevated.
There is also a potentially important consequence for economic growth. If financing constraints force technology companies to reduce capital expenditure, the resulting slowdown could affect semiconductor demand, construction activity and the broader investment cycle. That would create a difficult combination for markets, with weaker earnings expectations arriving before inflation has fully subsided.
Yesterday's selloff was not a verdict on AI's technological potential. It was a reminder that technological progress and attractive shareholder returns are different things.
The AI revolution may continue delivering extraordinary advances. Whether every company financing that revolution can generate equally impressive financial returns is becoming a much more demanding question.
The next phase of the AI boom will be determined less by how much companies are prepared to spend and increasingly by how much cash those investments can actually produce.
