TL;DR
Apple overtook Nvidia as the world’s most valuable company at the October 30 close, after a sharp selloff in technology stocks. Investors reacted to major spending on data centers and equipment by Amazon, Alphabet, Microsoft and Meta, while the companies’ cloud businesses continued to grow. Whether AI revenue will repay the spending quickly enough remains uncertain.
Apple overtook Nvidia as the world’s most valuable publicly traded company at the October 30 close, after technology stocks lost more than $1 trillion in market value in a single session. The selloff followed earnings reports that showed major technology companies spending heavily on AI infrastructure, prompting investors to question how soon that investment will generate returns.
Bloomberg figures published by The Straits Times put Apple’s market value at $5.03 trillion and Nvidia’s at $4.93 trillion at Friday’s close. Apple shares fell 1.2% that day, while Nvidia shares fell 4.2%. The ranking reflected a sharp move in prices, not a change in either company’s formal business status. Apple had last been ahead of Nvidia in late July, according to the source report.
On Thursday, October 29, Alphabet Class A shares fell 12.6%, their largest one-day drop since the company began trading in 2004, according to Fortune. NBC News reported that the decline erased about $500 billion in market value. The following day, technology stocks shed more than $1 trillion, NBC reported; the Nasdaq Composite fell 2.8% and the S&P 500 dropped 1.8%. The Nasdaq 100 lost 6.7% over October, its worst monthly performance since March 2025, according to Bloomberg.
The spending figures came from the companies’ third-quarter reports. Amazon reported $77.3 billion in purchases of property and equipment, Alphabet $51.4 billion, Microsoft $39.4 billion and Meta $33.9 billion. Each amount was roughly double the comparable figure a year earlier, according to the source material. These figures cover property and equipment, not AI alone, so they should not be treated as a precise measure of AI investment.

Investors Test AI Spending Returns
The market reaction reflects a shift in what investors want to know about AI: not only whether demand exists, but whether it can produce returns that justify the cost and arrive on a useful timeline. The spending figures are large, and some companies are signaling that the outlays may keep rising. Amazon chief executive Andy Jassy said the company expected to spend “meaningfully more in 2027,” NBC News reported.
At the same time, the companies reported strong growth in cloud services: Google Cloud revenue rose 103%, Microsoft Azure revenue rose 48%, and Amazon Web Services revenue rose 39%, according to the source material. Those results point to real customer demand, but they do not by themselves establish how much of the growth comes from AI or whether it will cover the cost of new facilities, servers and equipment.
For people and businesses using these services, the investment debate could affect the price and availability of AI products. The source report anticipates more advertising in AI answers, firmer service prices and terms, and greater competition for power, construction capacity and capital. Those are possible consequences, not confirmed changes announced by the companies in the material provided.

Three Sessions Reshape Market Mood
The reversal followed a sequence of earnings and trading moves. Alphabet and Microsoft reported after the market closed on Wednesday, October 28. Alphabet said revenue rose 25% to $127.6 billion, while its free cash flow turned negative for the quarter. Microsoft reported strong cloud growth and positive cash flow, according to the source material. Alphabet’s next-day share decline made it the most prominent early signal that investors were reassessing the cost of the AI buildout.
Amazon and Intel reported after Thursday’s close. Intel shares fell 29% after what the source described as a weak forecast. Amazon recovered from a steeper after-hours decline and finished Friday down 1.4%. On Thursday, about 400 S&P 500 stocks rose even as Alphabet plunged; the equal-weighted S&P 500 gained 1.2%, according to Bloomberg as published by The National. That suggests the pressure was concentrated in parts of the market rather than spread evenly across all shares.
The market’s movement also coincided with a shift toward safer assets. Reuters, as published by The Straits Times, reported that the 10-year U.S. Treasury yield was 4.91% in Asian trading on Friday, about 0.37 percentage points lower over October. The numbers provide context for investor positioning, but they do not establish that AI spending fears alone caused the moves.
““to spend meaningfully more in 2027””

AI Payback Remains Unmeasured
The reported figures do not show how much of each company’s capital spending is specifically for AI, nor do they establish the returns attributable to those projects. Cloud revenue growth is confirmed in the source material, but the share directly linked to AI, the infrastructure’s eventual utilization and the timing of any payback are not given.
The source also cites U.S. data showing data-center construction up 73% in a year while factory construction fell about 20%. Those figures are consistent with concern that data-center investment may be drawing resources away from other projects, but they do not prove that one trend caused the other. The article provides no complete evidence that AI spending is crowding out other investment.
The source report says Alphabet’s free cash flow was negative $9.1 billion for the quarter, Meta’s was negative $2.1 billion, and Amazon’s was negative $42.4 billion over 12 months; Microsoft remained positive. These measures cover different periods in Amazon’s case and are not, on their own, proof that AI projects caused the cash-flow results. Further company disclosures will be needed to assess spending, revenue and returns on a comparable basis.
Earnings Will Test Spending Plans
The next evidence will come from subsequent company earnings reports and any updates to capital-spending forecasts. Investors will be watching whether the companies follow through on plans for further investment, and whether cloud growth and other AI-related revenue continue alongside those costs. The source material does not specify a date for the next updates.
For now, Apple’s lead over Nvidia is a snapshot at one market close, while the wider selloff shows that investors are scrutinizing the financial consequences of the AI buildout. Whether the reassessment persists will depend on future results and guidance; the October share-price moves alone cannot answer whether the spending will pay off.
Key Questions
Why did Apple pass Nvidia in market value?
Apple shares fell less than Nvidia shares on October 30. At the close, Bloomberg figures published by The Straits Times valued Apple at $5.03 trillion and Nvidia at $4.93 trillion. It was a market-value ranking at that point in time.
What prompted the technology stock selloff?
The source report links the selloff to investor concern about the scale of spending on data centers, servers and equipment by Amazon, Alphabet, Microsoft and Meta, and uncertainty about when the investment will generate sufficient returns. The available material does not establish that this was the only factor behind the market moves.
How much did the four companies spend on equipment and property?
For the third quarter of 2026, Amazon reported $77.3 billion, Alphabet $51.4 billion, Microsoft $39.4 billion and Meta $33.9 billion in purchases of property and equipment. The amounts are not all AI-only spending.
Does cloud growth prove that AI investment is paying off?
No. The source reports strong cloud revenue growth at Google Cloud, Azure and AWS, but it does not quantify how much came from AI or show that AI-related returns have already covered infrastructure costs.
What remains uncertain after the selloff?
The companies’ AI-specific spending, the portion of cloud growth attributable to AI, and the timing and scale of returns remain unclear in the available information. It is also not established that data-center construction has directly displaced factory investment.
