Alphabet shares fell about 10% in premarket trading on October 29, 2026, putting the stock on course for their largest post-earnings decline ever. The drop followed a report of negative free cash flow larger than analysts had expected, even as Alphabet maintained its spending guidance for the year. A separate CNBC headline said Wall Street sold off the stock after an earnings miss that included weaker-than-expected revenue from the company's core business. CNBC framed the shortfall as a first real sign that AI is taking a bite out of search. The available reporting did not give the full quarterly figures.
