Alphabet Stock Falls as $205B Capex Plan Raises AI Spending Concerns

Alphabet shares fell nearly 5% in premarket trading Thursday after the company disclosed sharply higher capital expenditure plans to support its artificial intelligence infrastructure buildout, according to Yahoo Finance.

The stock closed below its 100-day moving average for the first time since April on Wednesday, a technical signal that could foreshadow a test of the 200-day moving average around $323. Alphabet had been the strongest performer among the "Magnificent Seven" tech stocks year-to-date before this week's earnings release.

Capex guidance jumps $15 billion

Alphabet reported second-quarter capital expenditures of $44.9 billion, marginally above Wall Street's $44.7 billion estimate. More significantly, the company raised its full-year capex guidance to a range of $195 billion to $205 billion, up from the previous $180 billion to $190 billion forecast. Executives indicated on the earnings call that 2027 would see a "significant" further increase in spending.

The elevated investment levels reflect the intense competition among cloud infrastructure providers to build out AI capabilities. Alphabet is deploying capital across data centers, custom chips, and networking infrastructure to support growing demand for AI services.

Strong results overshadowed by spending trajectory

The market's focus on capex overshadowed what was otherwise a robust quarter. Google Cloud revenue jumped 82% to $24.8 billion, while the division's backlog reached $514 billion—a measure of contracted future revenue that underscores enterprise demand for AI infrastructure.

CEO Sundar Pichai pointed to momentum across AI-integrated products including Search, YouTube, and the Gemini AI assistant as the company scales its AI ecosystem across properties.

Why it matters

Investor tolerance for massive AI infrastructure spending is being tested across the hyperscale cloud providers. While Alphabet's proprietary TPU chips and dominant distribution through Android and Chrome may provide cost advantages and monetization paths competitors lack, the market is demanding clearer evidence that these multi-hundred-billion-dollar investments will generate proportional returns. The technical breakdown suggests investors are reassessing whether current valuations adequately reflect the capital intensity of the AI buildout phase.

Pivotal Research analyst Jeffrey Wlodarczak maintained a positive view, arguing Alphabet remains best-positioned among peers to monetize AI investments through its chip advantages, distribution reach across 4 billion-plus devices, and potential for Gemini to capture market share.
