Alphabet and Tesla Shares Drop as AI Spending Surges

Shares of Alphabet and Tesla experienced significant declines on Thursday following announcements from both companies detailing plans to accelerate their already substantial artificial intelligence spending. This increase in projected expenditures has unsettled investors who are growing cautious about the potential returns on these massive investments.

Tesla's stock fell 10%, and Alphabet's shares dropped over 5%. These drops followed a weaker trading day on Wednesday, where Tesla closed down 1.3% and Alphabet was down 1.5%.

Alphabet, the parent company of Google, revised its capital expenditure forecast upward, now anticipating spending between $195 billion and $205 billion this year, with potential for further increases next year. This is an increase from its previous projection of $180 billion to $190 billion.

Tesla reported that its capital expenditures surged 142% in the second quarter compared to the previous year, reaching $5.79 billion. The company expects its capital expenditures for the current year to exceed $25 billion.

These announcements come at a time when investor anxiety regarding unchecked AI spending is mounting. Simultaneously, companies perceived as lagging in AI development have faced investor backlash. IBM's stock recently experienced its worst trading day since 1968 after its CEO acknowledged the company had "faltered" in its AI strategy, citing an underestimation of the industry-wide capital expenditure reprioritization.

Leaders at both Tesla and Alphabet sought to assuage investor concerns. Tesla CEO Elon Musk stated during an earnings call that the current year represents "a massive capex year" and expressed confidence that the investments would yield "incredible returns."

Alphabet CEO Sundar Pichai explained that the increased spending is "primarily due to an acceleration in the delivery of capacity to meet growing demand," highlighting the company's current lack of sufficient computing power to meet AI demand.

Analysts noted that investors are focusing on the sharp rise in capital expenditure and a potentially weaker margin outlook. Questions have also been raised about whether Alphabet's AI investments are translating into a clear competitive advantage, especially in light of reported delays with Gemini 3.5 Pro and a lack of significant new product releases.

Despite the concerns about future spending, some aspects of the companies' recent earnings showed positive signs. Both companies reported negative free cash flow for the second quarter. However, Alphabet's cloud revenue increased by 82% to $24.8 billion, surpassing forecasts, indicating that some of its investments are yielding results.

Tesla's core automotive business generated $20.52 billion in revenue, marking a 23% year-on-year increase. Analysts have described Alphabet's strong revenue growth as an encouraging sign for overall AI capital expenditures and the returns these platforms are seeing on their spending.
