Wall Street moved lower on Thursday, October 29, 2026, after Alphabet's quarterly revenue fell short of expectations, according to Reuters. The miss revived concerns among investors about how much the company is spending on artificial intelligence.
Alphabet's stock dropped sharply on the results. CNBC reported a 12% decline, which would mark the company's largest post-earnings fall on record. The Economic Times put the drop at 13% and tied it to a $9 billion cash burn that heightened fears over AI spending. Reuters also reported that search-related troubles contributed to the revenue shortfall and that the cash burn worsened.
The reaction spread beyond Alphabet, with Reuters describing a broader slide across Wall Street as the AI capital expenditure worries returned. The Financial Times framed the moment around Google's internal pressures while suggesting the company could still compete strongly against rivals.
Investors are weighing whether heavy AI investment will translate into revenue growth or continue to weigh on results and cash flow. Alphabet has not commented in the reporting summarized here.
What to watch next: whether Alphabet provides further detail on its AI spending plans and whether other major technology companies face similar investor scrutiny when they report results.
