Meta AI spending plan rattles investors amid AI arms race

Meta’s stock slid about 7% in after-hours trading after it revealed a plan to lift its capital expenditure on AI to as much as $145 billion, up from a previous ceiling of $135 billion. The move comes as Meta joins Alphabet, Microsoft and Amazon in pouring hundreds of billions into artificial intelligence this year, a total that has already crossed the $650 billion mark and has investors weighing the potential rewards against the hefty price tag.

Analysts have grown increasingly wary about the sustainability of what many call an AI boom, given the high costs and the lack of clear, real-time gains. “There is anxiety about whether the AI push can be sustained and translate into lasting value,” said a tech industry analyst.

Meta’s own numbers reflect the gamble. CFO Susan Li said Meta had underestimated its compute needs in the past and needed to spend more to meet them, while CEO Mark Zuckerberg acknowledged there isn’t a precise, step-by-step plan for how each AI product will scale. The ambition is to accelerate results from AI across its platforms, but the lack of a detailed roadmap underscores investor concerns about timing and returns.

By contrast, Alphabet, Microsoft and Amazon reported earnings that suggested their heavy AI investments are starting to pay off, with investors reacting more positively to their results. In particular, Amazon’s cloud unit and related AI partnerships have bolstered profits, underscoring a broader market belief that AI leadership could unlock meaningful upside for the biggest tech players.

As the AI arms race intensifies, analysts say the true test will be whether these firms can turn ambitious spending into durable competitiveness and tangible product wins. Until then, Meta’s latest move remains a focal point for questions about cost, timing and eventual payoff in the sprawling AI economy.
