Apple’s record September quarter and a fresh wave of AI spending from the biggest tech firms are setting near-term market currents and longer-term infrastructure trajectories. Apple (NASDAQ:AAPL) posted a September-quarter revenue record of $102.5 billion and GAAP EPS of $1.85, powering a rally that pushed its market value past $4 trillion. Microsoft (NASDAQ:MSFT) reported Azure growth of 40% and flagged roughly $35 billion in AI-related capital spending. META Platforms (NASDAQ:META) signaled much larger capital expenditures and plans for a roughly $30 billion bond raise — moves that prompted a stock pullback of more than 11% and knocked major indexes lower. Globally, the spending arms race accelerates data-center builds in the U.S., Europe and Asia, while a U.S.-China trade truce (tariffs still near ~30%) eases some export-control risks. In the short term, markets are reacting to funding and margin questions; over the long term, the race to scale GPUs, power and real estate is likely to rewrite where AI compute lives and who controls it.

Earnings pulse: Apple, Microsoft and Meta set the tone

Apple (NASDAQ:AAPL) reported September-quarter revenue of $102.5 billion, up 7.9% year-over-year, and GAAP EPS of $1.85. The company said iPhone demand and services sales drove the record quarter. Investors cheered: Apple briefly traded near all-time highs and joined an exclusive group above a $4 trillion market cap.

Microsoft (NASDAQ:MSFT) beat on top and bottom lines while disclosing a surge in AI-related capital intensity. The firm reported Azure revenue growth of 40% and disclosed roughly $35 billion of capex to expand data-center capacity and other AI infrastructure. The company also highlighted a restructured partnership with OpenAI valued at about $135 billion and signaled plans to double data-center footprint over coming years.

Meta Platforms (NASDAQ:META) reported mixed results and then warned of “notably larger” capital spending next year to support AI. Management’s plan to raise cash — reports cited a roughly $30 billion bond offering — and the bigger capex outlook prompted a sharp market reaction. Meta shares slid more than 11% the day after the announcement, and the S&P 500 and Nasdaq fell about 1% and 1.5% respectively on the same session.

The AI capex race: GPUs, data centers and sovereign plays

Big Tech’s results reveal a single, clear driver: capacity. Companies are buying GPUs, building data-center campuses and making long-term commitments to power and real estate. Nvidia (NASDAQ:NVDA) remains the hardware focal point; it recently became the first public company to surpass a $5 trillion market cap, reflecting extraordinary demand for AI accelerators.

Oracle (NYSE:ORCL) and OpenAI announced a 1‑gigawatt data-center site in Michigan as part of a larger Stargate program. Industry commentary in the announcement put the order-of-magnitude cost for 1 GW around $50 billion, and the Stargate pipeline expands to 4.5 GW in the near term and more than 8 GW in planned capacity — a multi-hundred-billion-dollar infrastructure wave (materials in the release put total planned investment to over $450 billion across sites).

Regionally, South Korea and Saudi Arabia are courting GPU and cloud investments: Nvidia is deepening ties in South Korea, and Qualcomm (NASDAQ:QCOM) partnered with Saudi projects to seed AI infrastructure. The U.S.-China truce softened some export-control pressures, but tariffs remain near 30%, and that uncertainty shapes where firms choose to site sensitive compute.

Market reaction, risks and the immediate watchlist

Markets punished companies that raised the specter of financing or near-term margin pressure. Meta’s (NASDAQ:META) bond plans and higher capex drove an outsized share decline of more than 11% and helped push the Nasdaq and S&P lower. Microsoft’s (NASDAQ:MSFT) disclosure of a roughly $35 billion capex program produced a pullback too — investors weighed faster growth against margin dilution.

At the same time, Apple’s (NASDAQ:AAPL) EPS beat and record revenue supported a rotation back into consumer hardware and services stocks. Amazon (NASDAQ:AMZN) and other cloud names also posted results that reframed expectations: AWS revenue acceleration helped Amazon stay resilient even after a major outage earlier in the quarter.

• Apple’s record quarter ($102.5B revenue, $1.85 EPS) underlines consumer and services strength heading into holiday demand.
• Microsoft’s Azure +40% growth and ~$35B capex show how quickly cloud providers must scale to meet AI compute demand.
• Meta’s plan for higher capex and a ~$30B bond raise is already costing the stock in the near term.
• Oracle/OpenAI’s 1 GW Stargate site illustrates the scale — and price tag — of public‑cloud and sovereign-AI commitments.
• Nvidia (NASDAQ:NVDA) hitting a $5 trillion valuation highlights the asymmetry of AI hardware winners and the broad ripple effects across chip suppliers and data-center builders.

In addition to earnings flow, keep watching four near-term signals: reported capex and financing plans from Big Tech; GPU supply and order books; progress on large data-center projects (Stargate milestones, permits, power procurement); and macro inputs such as Fed guidance and U.S.-China trade measures (tariffs still referenced at about 30% in recent summaries). These will drive volatility and determine how much of the current spending converts into sustainable revenue growth versus just higher operating leverage.
