Investors wiped billions from the market value of Alphabet and Tesla after the companies disclosed another sharp increase in spending tied to artificial intelligence, signalling that Wall Street is becoming less willing to reward ambitious investment plans without clearer evidence of when those outlays will generate stronger financial returns.
Alphabet's shares fell nearly 7%, while Tesla tumbled 14.5% following the release of their latest quarterly earnings. Although both companies remain committed to expanding their long-term technology capabilities, investors focused on a different figure: free cash flow. Each company reported that the cash remaining after funding operations and capital investments had turned negative, raising fresh questions about the financial burden created by large-scale AI and infrastructure projects.
The reaction illustrates a growing divide between technology companies and financial markets. Executives continue to argue that today's spending is necessary to secure future leadership in artificial intelligence, while investors are looking for clearer signs that those investments will eventually translate into stronger earnings and cash generation.
Alphabet's quarterly revenue climbed to $119.8 billion, a 23% increase from the same period a year earlier, showing that demand across its businesses remained healthy. Yet strong sales did little to ease investor concerns because the company's capital spending accelerated even faster.
For the quarter, Alphabet reported negative free cash flow of $5.9 billion, the first such result since the company became publicly listed in 2004. Free cash flow is closely watched by investors because it measures how much cash remains after a company pays its operating expenses and funds long-term investments. A negative figure does not necessarily indicate financial weakness, but it does show that investment costs exceeded the cash generated during the period.
Alphabet Chief Financial Officer Anat Ashkanazi told financial analysts that the decline was driven almost entirely by AI-related capital expenditure. The company invested approximately $45 billion during the quarter, allocating around 60% of that spending to servers and the remaining 40% to expanding data centre capacity needed to support growing demand for AI services. The latest figure also represents a substantial increase from the $36 billion Alphabet invested during the previous quarter.
The company has now lifted its projected capital expenditure for the year to as much as $205 billion, roughly $15 billion higher than the estimate it provided three months ago. Most of that investment will support AI infrastructure, including computing resources capable of training and operating increasingly sophisticated artificial intelligence models.
Ashkanazi said customer demand for AI products continues to exceed the company's available computing capacity, adding that Alphabet intends to keep investing while opportunities remain attractive.
Chief Executive Officer Sundar Pichai described artificial intelligence as a technological transition that is still in its early stages. He said the company remains disciplined in evaluating where it allocates capital and believes substantial opportunities remain to transform advanced AI capabilities into products and services used by businesses and consumers.
Tesla reported a similar financial picture. The electric vehicle manufacturer posted negative free cash flow of $1.1 billion during the second quarter, its first negative reading in two years, after investment costs climbed across several strategic initiatives.
The company expects capital expenditure to reach as much as $25 billion this year, more than double what it invested during 2025. While Tesla has not disclosed a detailed breakdown of every project included in that forecast, the spending is expected to support manufacturing expansion, autonomous driving technology, robotics, AI development and the computing infrastructure required to power those initiatives.
Tesla Chief Financial Officer Vaibhav Taneja said the company is entering a major investment cycle and expects spending to continue rising over the next three years as those programmes move forward.
Market analysts say the concern is not that technology companies are investing in artificial intelligence, but that the scale of spending has reached levels that demand measurable financial returns. Russ Mould, investment director at AJ Bell, said investors remain sceptical that such unprecedented expenditure will produce returns proportionate to the capital being committed.
Rachel Winter, a partner at wealth management firm Killik & Co, also noted that Alphabet's latest investment plans exceeded many expectations, suggesting the market's response indicates unease about the pace at which those billions of dollars will translate into higher profits.
The earnings from Alphabet and Tesla arrive as the technology industry commits record sums to artificial intelligence. Companies including Microsoft, Amazon and Meta have all expanded spending on specialised chips, cloud infrastructure and data centres to support rapidly growing AI workloads. As competition intensifies, capital expenditure has become one of the defining financial themes shaping the sector.
For investors, however, enthusiasm for artificial intelligence is now accompanied by tougher questions. Revenue growth alone is no longer enough to reassure the market. Companies are now expected to show that record-breaking investment in AI infrastructure can eventually deliver sustainable profits, stronger cash generation and lasting value for shareholders.
