Investors Trust Google Over Meta on AI Spending
Major US tech firms — Amazon, Google/Alphabet, Microsoft and Meta — plan to spend as much as $725 billion this year on AI-related capital expenditure, focused largely on data-center and infrastructure expansion. Amazon previously flagged roughly $200 billion in investment; Meta raised its capex guidance by $10 billion to $125–145 billion; Alphabet increased its guidance by $5 billion to $180–190 billion; Microsoft aims for around $190 billion. Investors reacted mixed: Meta shares fell more than 6% after hours while Alphabet/Google rose about 7%. Strong cloud growth underpins the spending: Google Cloud revenue rose ~63% to ~$20 billion, AWS revenue grew ~28% to ~38 billion, and Microsoft forecast ~40% Azure revenue growth. Company chiefs warned of a transformational AI opportunity but acknowledged concerns about return on these large investments.
Meta's AI Spending and the Stock's Next Move
Meta Platforms is undertaking an aggressive AI-driven investment program — planning up to $169 billion in spending this year concentrated on AI infrastructure, custom silicon and cloud commitments — and investors are watching whether those investments are translating into stronger ad monetization and profit growth. Recent moves include a multibillion-dollar partnership to deploy AWS Graviton processors, a $21 billion commitment to CoreWeave (adding to a prior $14.2 billion agreement), and an agreement worth up to $27 billion with Nebius. Meta released Muse Spark, a multimodal foundation model, and reorganized AI work under Chief AI Officer Alexandr Wang. The company also announced workforce reductions of about 8,000 roles and paused hiring for roughly 6,000 open positions. Wednesday’s earnings report is framed as a key test of whether Meta’s AI spending is producing measurable returns for its advertising business.
Meta's AI Investments Pay Off via Ads and New Agent
Meta Platforms is showing evidence that its massive AI investment is yielding returns, according to two new research reports. Bernstein highlights that AI is helping Meta capture a larger share of digital ad dollars, with ad revenue growing 27% year-over-year in Q2 2026, outpacing Google's network and gaining two percentage points of market share. Bank of America points to Meta's upcoming consumer AI agent, Hatch, which could open new revenue streams beyond ads, with a potential premium subscription tier priced up to $199.99 per month. However, Meta remains the worst-performing megacap tech stock this year, down over 12%, as investors question the ROI. The company raised its capex guidance midpoint to $137.5 billion and agreed to pay up to $18 billion to settle youth addiction claims. The report suggests Meta may need a public cloud business to monetize excess computing power.
