Quick Summary

US tech stocks are experiencing sharp declines due to rising concerns about the high costs associated with developing artificial intelligence technology. Intel's stock plummeted by 30% after the company warned of a weaker computer market despite plans to increase AI spending, resulting in a loss of over $130 billion in value. The broader Nasdaq tech index opened at its lowest point in two months, down 2.5%, with other companies like Amazon and Google's parent Alphabet also suffering significant drops in stock prices following disappointing earnings reports and revenue forecasts.

Story summary

On October 29, 2026, Google's parent company Alphabet saw its stock price plummet by up to 15.8%, resulting in a one-day market value loss of over $500 billion, the worst ever for the company. This drop was largely due to concerns about artificial intelligence (AI) investments not yielding returns quickly enough and fears that AI chatbots might be eating into Google's traditional search business. Despite executives touting more than 1 billion users of its Gemini AI app and promising "promising results" from ad experiments, the market reacted negatively to missed revenue targets and negative cash flow for the second consecutive quarter. This event also affected broader markets, with tech-heavy indexes like the Nasdaq dropping significantly amid a wider reassessment of US economic growth and sustainability in rapid AI spending by major tech companies.

🔮 - Published Halloween shoppers in the US seeking sweet relief this spooky season have instead been shocked by the high price of seasonal treats, as cost of living pressures continue to bite. Demetrio Beltres, a 33-year-old financial adviser searching for Halloween bargains for trick or treaters said he was spending more than his usual $15 (£11) to $20 this year because prices were much higher. "I'm trying to spend at least $20 to $30 just to make sure that I get the kids something," he said, while browsing the rows of colour options at a Target in Manhattan. A lot of people are finding they are in the same boat as Demetrio this year. Stephen Zagor, adjunct associate professor at Columbia Business School, said people have only so much to spend, and when everyday essentials are costing more, people may feel less inclined to make this the most extravagant Halloween.
