AI investments pressure big tech stocks after earnings
🎧 Listen to this story
Rising spending on artificial intelligence infrastructure has led markets to question when major technology companies will turn those investments into profit. After quarterly results were released, Alphabet shares fell 12.64% on October 29, wiping US$493.9 billion from its market value, according to a study by consulting firm Elos Ayta. Amazon, Meta and Microsoft also contributed to a combined loss of nearly US$900 billion across the four companies.
The pressure spread across the market: on October 30, the Nasdaq fell 2.9%, while shares of Intel, Nvidia and AMD dropped 28.6%, 4.2% and 10.9%, respectively. Intel also warned that it would consume cash, citing weakness in the personal-computer market, chip-manufacturing difficulties and high investment. According to the Bloomberg Billionaires Index, Larry Page, Sergey Brin and Jeff Bezos together lost about US$70.18 billion in estimated wealth, mainly because their holdings declined in value.
Why it matters · editorial interpretation
The episode suggests that markets are assessing not only the scale of investment in AI infrastructure, but also how long it may take for that spending to translate into profit. The reaction affected major technology companies, chipmakers and the estimated wealth of their founders, extending the impact beyond individual earnings reports.
