ECONOMY STUDIOMore than $2 trillion of market value was set to be wiped from the Nasdaq-100 in October 2026, Reuters reported on October 301. On Thursday, October 29, Alphabet’s shares fell 12.6%, about $500 billion, its worst day since it began trading in 20042.
Alphabet had just reported a record quarter. The reason for the fall was in its cash.
A record quarter, and a cash outflow
Alphabet’s revenue was $127,577 million in the third quarter, up 25%3. Its business produced $42,290 million of cash from operations, but it spent $51,355 million on property and equipment, so its free cash flow was negative $9,065 million4. It was the second negative quarter in a row, and CNN reported it had never had one from its 2004 listing until this year4,5.
That is $121 of spending for every $100 of cash the business made6. Alphabet is not alone.
Four builders, one gap
Amazon spent $77,259 million on property and equipment in the quarter, more than double the $35,095 million of a year earlier7,8. For every $100 of cash from its operations it spent about $1828. Its free cash flow for the last 12 months was an outflow of $42.4 billion, against an inflow of $14.8 billion a year earlier, and Amazon says the increase primarily reflects investments in artificial intelligence7.
Meta spent $34.91 billion against $32.79 billion of operating cash9. Microsoft was different: $58,000 million of operating cash and $39,367 million of capital spending, about $68 per $100, leaving $18,633 million10.
Added together, the four spent $202,891 million on data centers and gear against $175,502 million of cash from operations11. That is $116 for every $100, so about $16 of every $100 was missing before any dividends or buybacks11.
The numbers behind it are huge. J.P. Morgan expects global AI capital spending of about $900 billion in 2026, and Morgan Stanley forecasts more than $1 trillion next year12. Amazon alone says it expects about $220 billion of cash capital spending in 20267.
Where the missing money comes from
When cash from the business falls short, the rest comes from investors and lenders. In the third quarter, Alphabet raised $12.4 billion by selling new shares and $28.7 billion by selling bonds, $41.1 billion together, with $27.6 billion of share sales still available under its program4.
Meta raised its planned equity financing to $97.5 billion, the largest equity offering in its history13. It includes $25 billion of ordinary shares priced at $625 each, about 12.5 billion dollars of convertible preferred stock and a program to sell up to $60 billion of shares over time from 202713,14. Meta’s own release said a new non-voting share class would “provide Meta the ability to finance its growth”9. This is a plan, not money collected13.
Microsoft is raising about $25 billion in its first U.S. investment-grade bond sale in more than nine years15.
The market that pays
This is where it reaches a retirement account. In a Nasdaq-100 fund, about $19 of every $100 sits in Alphabet, Amazon, Meta and Microsoft, and about $8 in Nvidia16. Gallup found that 62% of U.S. adults say they own stock, including through funds and retirement accounts17.
The same is true abroad. Britain’s most-bought index fund in September was a global tracker that holds 62% in the United States, about $62 of every $10018.
So when the market is asked to fund the AI buildout, an investor in a tracker is already holding the companies that are asking16.
What the market said
The Nasdaq Composite closed at a record 27,599.79 on October 6 and at 25,437.00 on October 30, down 7.8%19. October was its worst month since March 2025, down 5.3%19. A $100 holding in a Nasdaq-100 tracker on October 6 was worth about $91 on October 3020.
The sorting was harsh. On October 30, Reddit fell 29.2%, Intel 28.6%, AMD 10.9%, Nvidia 4.2% and the Nasdaq-100 3.5%21,22,19. Intel’s was its biggest one-day loss on record, after it warned it would burn cash this year22.
Reddit shows it is not only about data centers. It spent $1 million on capital expenditures in the quarter, and its shares still fell after its chief executive warned that daily visitors could fall in the fourth quarter23.
Analysts read it differently. Art Hogan of B. Riley Wealth sees a rotation out of a crowded technology trade into safer havens, not a broader reset24. Ted Mortonson of Baird said: “Everybody is trying to get through the door at the same time, and it gives people pause”5. These are views, not facts.
The Fed and the 10-year
The Fed held its target range at 3.75-4.00% on October 28 by 10 votes to 2, with two members preferring a rise of a quarter point25. The 10-year Treasury yield closed at 4.94% on October 30, and markets expected Fed rises of more than 50 basis points by mid-2027, according to LSEG data cited by Reuters26,27. The next Fed meeting is December 8-925.
What to take from it
None of this says what to do. It shows how the AI buildout is paid for: the businesses are growing fast, but the cash they produce is no longer enough to cover what they spend. The difference is raised from shareholders and lenders, which is why a record quarter could still cost Alphabet about $500 billion in a day2,11.
The boom is real. Amazon’s AWS grew 39.3%, its fastest in nearly five years, and Microsoft’s Azure grew 48%28,10. What the market is weighing is who pays for the building while the revenue catches up.
