Alphabet, Microsoft, Amazon and Meta Platforms will report first-quarter earnings after the market close on 29 April. Bloomberg reported that the four sets of results will land within roughly 80 seconds of each other, making it the most concentrated burst of mega-cap earnings in market history.

Why it matters

These four companies have committed between $600 billion and $645 billion in AI infrastructure spending for 2026 alone. Whether that investment is generating real revenue or simply inflating costs will shape the direction of global equity markets for the rest of the year.

The spending breakdown

Amazon leads with roughly $200 billion in planned capital expenditure, followed by Alphabet at $175 billion to $185 billion, Meta at $115 billion to $135 billion and Microsoft at an estimated $120 billion based on its most recent quarterly run rate of $29.88 billion.

The money is flowing into data centres, Nvidia GPUs, and proprietary chips. Meta’s MTIA 450 chip, Google’s TPUs sold to labs including Anthropic, and Amazon’s Trainium processors all represent efforts to reduce dependence on Nvidia.

The bull case

Supporters of the spending argue that AI is driving genuine revenue growth. Microsoft’s 365 Copilot has added millions of enterprise subscribers. Google Cloud grew 35% year-over-year last quarter, powered by Gemini adoption. AWS reported a record backlog of cloud contracts in the prior quarter.

Alphabet is expected to post revenue of $92.2 billion, up 20.6% year-over-year. Microsoft is expected at $81.4 billion, up 16.2%.

The bear case

Critics point to the gap between capital expenditure and measurable returns. Meta’s $115 billion minimum spend comes after it cut 8,000 jobs on 24 April. The semiconductor rally that pushed the Philadelphia Semiconductor Index up 39% in April has left valuations stretched, and any earnings miss could trigger a sharp reversal.

OpenAI’s latest revenue report, released on 28 April, showed slower-than-expected growth in enterprise subscriptions, sending the Russell 2000 and Nasdaq lower.

What happens next

Results land after 16:00 Eastern time on 29 April. Apple reports on Thursday, completing the Magnificent Seven earnings cycle for the quarter. Analysts say the key metric is not top-line revenue but the ratio of AI-related capital spending to AI-related revenue growth. A widening gap between the two would renew concerns about overinvestment.
