Tech stocks crash: Google has its worst day ever and Intel falls 28%. What’s happening with AI stocks?
On Friday, more than $1 trillion was wiped off tech stocks. Alphabet had its worst day since 2004, Intel its worst since 1974, and the Nasdaq its worst since June. Here's what happened and why investors are nervous about AI.
It was a brutal end to the week for tech stocks. On Friday, October 30, 2026, more than $1 trillion in value was wiped off tech companies in a single day, as investors grew nervous about the cost of the AI boom.
The biggest moves
- Nasdaq: down 2.86%, its worst day since June, and down 5.3% for October
- Alphabet (Google): down about 12.6%, its worst day since its 2004 stock market debut, erasing roughly $500 billion in value
- Intel: down about 28.6%, its worst day since 1974
- Chip stocks: the Philadelphia semiconductor index fell 7.2%; AMD dropped about 11% and Nvidia about 4%
- S&P 500: down 1.82%
Apple held up relatively well, and according to market reports it ended the day as the world’s most valuable company.
Why Google fell so hard
Alphabet’s results this week showed Google Cloud more than doubling, but profit missed expectations, search and YouTube ad growth slowed, and spending on AI data centers more than doubled. Investors worry that AI chatbots could slowly take attention away from Google Search. Read our Microsoft vs Google earnings breakdown.
Why Intel crashed
Intel’s latest quarter was actually good: revenue rose 21% to $16.5 billion, and data center and AI sales jumped 78%. But its forecast scared investors:
- Next-quarter revenue: $15–16 billion, below the ~$17.1 billion expected
- Next-quarter profit per share: $0.25, far below the ~$0.43 expected
- PC slowdown: CEO Lip-Bu Tan said customers are buying fewer PCs because of high memory prices. CFO David Zinsner expects the slowdown to continue “at least through the first half of next year.”
- Factory problem: an accident at Intel’s factory in Israel caused a long shutdown that will reduce server chip shipments.
The drop also cut about $12 billion from the value of the US government’s roughly 10% stake in Intel, according to CNBC.
The AI boom is creating winners and losers at the same time: AI data centers are booming, but the memory they consume is making everyday PCs more expensive.
The bigger worry: is AI spending paying off?
Big tech companies are spending hundreds of billions of dollars on AI data centers. This week:
- Amazon spent $77.3 billion in one quarter, and its stock fell after a profit miss
- Alphabet spent $51.4 billion, and its free cash flow turned negative
- Meta announced a giant stock sale to pay for AI
Investors are asking how long companies can spend this much before profits catch up. When results disappoint, stocks fall fast.
What it means for you
- If you invest: big one-day drops are scary but not unusual in tech. Avoid panic decisions, and remember ByteTidings doesn’t give financial advice; talk to a licensed adviser if you need help.
- If you’re buying a PC or laptop: memory shortages are pushing prices up. Here’s why, and how to save.
- For AI products: spending on AI isn’t stopping. Amazon’s CEO said the company will keep investing.
