Alphabet, the parent company of Google, saw its total market value drop by more than $500bn on Thursday following its latest quarterly update. The decline reflects growing investor concern over the massive financial burden of artificial intelligence investments and their impact on core business lines.
The company’s stock hit a six-month low as it revealed that AI summaries in its search engine were negatively affecting advertising revenue. This is the primary source of income for Alphabet, making the shift in user behavior a critical issue for the tech giant.
Heavy AI Spending Drags on Profits
While total revenue grew 25% to $127.6bn, driven largely by a 103% surge in Google Cloud revenue to nearly $31bn, profits fell by 25%. For the second time in its history as a public company, Alphabet reported negative free cash flow, exceeding $9bn. This figure is nearly double the cash loss recorded just three months prior.

CEO Sundar Pichai has defended the company’s aggressive spending on AI infrastructure. However, the financial reality is that Alphabet is now spending more cash than it generates, with the vast majority of that outflow dedicated to AI development.
By the end of Thursday, the company’s total market capitalization had fallen to $3.46 trillion from $3.97 trillion the previous day. This represents a loss of approximately $500bn in total value, a figure that rattled investors and contributed to the stock’s 13% drop, its second-worst performance of the year.
Search Ads and Competitor Struggles
Google now defaults to AI-generated summaries for search queries. This change has reduced the number of advertisements that can be displayed alongside results, directly impacting the company’s most lucrative business segment. Phillip Schindler, Google’s chief business officer, expressed confidence in the trajectory of the AI-focused search engine, but the market reaction was immediate and severe.

The trend of heavy spending impacting stock prices was not unique to Alphabet. Microsoft and Amazon also reported disappointing results this week, highlighting a broader tension in the technology sector. Investors are increasingly wary of how astronomical AI investments are affecting the growth of established businesses.
Amazon shares fell 6% in after-hours trading after the company reported negative cash flow of $42bn, a six-fold increase over three months. CEO Andy Jassy cited opportunities in custom computer chips and the AI developer platform Bedrock as future growth drivers, though he admitted the current spending pace is intense.

Microsoft shares fell less than 1% despite reporting a $5bn reduction in AI investment spending. The company also announced plans to cut thousands of jobs to reduce costs. Revenue grew 19% to $92.3bn, with cloud revenue up 30% to $63bn.
Tracy Woo, a principal analyst at Forrester, noted that the results highlight the difficulty of funding massive AI investments while maintaining the strength of established businesses. She added that Wall Street is looking further into the future to determine where AI value will ultimately be captured in the technology industry.
