US Hyperscalers to Spend Up to $725 Billion on AI Infrastructure in 2026
The top five US hyperscalers are projecting a combined capital expenditure of $660 billion to $725 billion for 2026, nearly double their 2025 outlays, as the AI build-out shifts from software to physical infrastructure. Microsoft is guiding for roughly $175 billion in adjusted capital expenditure for both FY2026 and FY2027, with two-thirds of quarterly spend going to short-lived assets like CPUs and GPUs and the rest to long-lived data center infrastructure, and it added 1 gigawatt of capacity in Q3 FY2026, doubling its global footprint in two years. Amazon AWS has raised its 2026 capex guidance to approximately $220 billion, with CEO Andy Jassy saying AI capacity is expected to remain constrained through 2027 and contracted demand extending into 2028. Meta saw profit drop 14% in Q2 2026 despite a 28% revenue increase as its build-out, including a 1 gigawatt data center in Ohio and a Louisiana facility that could scale to 5 gigawatts, compressed margins, while Alphabet raised its 2026 capex guidance to as much as $205 billion and its Google Cloud backlog more than doubled year-over-year to $240 billion. The Stargate joint venture involving Oracle, OpenAI and others targets up to $500 billion in infrastructure investment by 2029, and Oracle's FY2026 capex reached $55.7 billion, more than doubling from the previous year.

Citi: Data Center Opposition Has Not Weakened AI Construction Pipeline
Citi says growing political opposition to artificial intelligence infrastructure ahead of the November U.S. midterm elections has not materially weakened the data center construction pipeline. Data center development has become a bipartisan flashpoint, with local governments introducing moratoriums and at least 15 state legislatures proposing tighter regulatory restrictions, yet spending remains strong as AI infrastructure demand continues to support development. The impact has been concentrated among speculative and early-stage projects, which are increasingly delayed or cancelled during local approval processes, while late-stage developments that have already secured sites and grid connections continue to move ahead. Hyperscalers are seeking workarounds to power constraints and local restrictions, with Amazon pursuing direct investment in nuclear development with Dominion Energy and Meta securing a major nuclear power purchase agreement with Constellation Energy. Citi does not expect another market shock comparable to the emergence of DeepSeek, arguing investors have already adjusted to the prospect of highly efficient Chinese models, though it flags a potentially greater risk from governments restricting models deemed too dangerous, which could abruptly create excess computing capacity.

Caterpillar Expands Robot Trucks to Two More Virginia Quarries
Caterpillar announced on September 15 that its self-driving haul trucks at a Luck Stone quarry are moving large tonnage, with expansion to two more Virginia quarries, Boscobel and Bealeton, including the first autonomous deployment of Cat 775 trucks. The company disclosed no order value, truck count, or profit contribution from the autonomy milestone, and autonomy was named on the earnings call only as a source of higher SG&A and R&D expenses inside Resource Industries. In the second quarter of 2026, revenue reached $20.5 billion, up 24% year over year, with adjusted EPS of $8.17, up 73%, while backlog climbed to $72 billion, up roughly $35 billion versus a year earlier. Power & Energy is the engine, with segment sales up 17% to $8.2 billion and power generation sales up 72% on large gensets and turbines for data centers, and gas prime orders extend toward the back half of 2028 and into 2029. Caterpillar trades at $798.51 against a consensus analyst target of $975.61, a trailing PE of 34x, and full-year tariff costs of around $2.2 billion for 2026, with expected IEEPA tariff recoveries of approximately $400 million.
