Alphabet Plunges 10% in Premarket, Battered by Negative Cash Flow and Search Pressure

Alphabet Inc. shares tumbled 10% in premarket trading on Thursday (29/10/2026) after the technology giant reported negative free cash flow of US$9.07 billion for the third quarter, far exceeding analyst estimates that had anticipated a deficit of only US$2.70 billion. If the decline continues through the close and exceeds 9.77%, it will mark the worst post-earnings reaction in the history of the company, which has been publicly listed since 2004.

Alphabet's poor performance contrasts with Microsoft, whose shares actually rose nearly 4% in premarket trading. Microsoft recorded capital expenditures and finance leases of US$45.2 billion, or 30% higher than last year, but still below analyst projections of US$50.67 billion. Microsoft's free cash flow did fall 27% to US$18.63 billion, but remained positive. Meanwhile, Alphabet maintained its full-year capital expenditure guidance in the range of US$195 billion to US$205 billion, an enormous figure that raises questions about return on investment.

The main pressure comes from the search advertising business that is the backbone of Alphabet's revenue. In the September quarter, the segment grew 12% to US$63.35 billion, but still failed to meet market expectations. Philipp Schindler, Alphabet's Chief Business Officer, acknowledged that one cause was lower monetization in the company's AI Mode feature. He said Alphabet is now expanding ad placements in its AI Overviews and AI Mode products, including in international markets.

Nevertheless, the move is seen as insufficient to address structural challenges. Google faces fierce competition from AI chatbots such as OpenAI's ChatGPT and Anthropic's Claude, which users increasingly turn to for searches outside the Google ecosystem. Gemini, Google's own chatbot, is seen as unable to close the gap. Ben Barringer, Head of Global Technology Research at Quilter Cheviot, said Alphabet is caught in an innovator's dilemma. "Google doesn't know whether to protect its core business or join the disruption. As a result, Gemini has lost competitiveness and fallen behind rivals in agentic AI," he said, as quoted by CNBC.

"Microsoft built its architecture in a measured way, so there are fewer surprises. Alphabet, by contrast, saw its share price pressured after hours due to messy results and a poorly handled earnings call," Barringer said.

The market reaction was not reflected only in Alphabet shares. Nasdaq-100 futures fell more than 1% on Thursday morning, signaling broader concerns about the technology sector. Investors are now increasingly critical of the AI spending plans of giant companies, shifting from growth euphoria to demands for real profits. Over the past few quarters, the market has signaled that it is no longer willing to finance unlimited expansion without clear evidence of returns.

For Indonesia, this turmoil in US technology stocks warrants attention. AI technology and cloud services from Alphabet and Microsoft are linked to the national digital ecosystem, from infrastructure service providers to startups that depend on their platforms. A decline in capital expenditure or a shift in global AI strategy could affect service availability and the operating costs of Indonesian startups. In addition, negative sentiment toward global technology stocks could spill over into the domestic capital market, especially technology sector shares listed on the Indonesia Stock Exchange.

Looking ahead, the big question is whether Alphabet can turn things around. The company needs to prove that massive investment in AI is not merely draining cash but also generating sustainable revenue growth. While Microsoft appears more confident with a more controlled spending approach, Alphabet stands at a crossroads: maintaining search dominance or fully transforming for the AI era. The market will wait patiently, but investor patience appears to be wearing thin.
