- S&P 500 closed at a record 7,736.52, up 1.8% on Tuesday, capping a nearly 6% rally over four sessions after the index failed to advance in June and July.
- Palantir Technologies surged 29.5% after Q2 results showed strong sales of its AI software platform to corporate clients, reinvigorating the AI trade and lifting chip, semiconductor, and data-center hardware stocks.
- Microsoft, Amazon, and Alphabet posted quarterly results that drove massive gains in the same Mag 7 names that had become the 'Lag 7' after a June air pocket erased over $1 trillion in chip-stock value.
- 2026 hyperscaler capital expenditures expectations climbed from $487 billion in early February to $840.1 billion by Aug. 3-4, per FactSet consensus for Amazon, Alphabet, Meta, Microsoft, and Oracle.
- Energy shares are the S&P 500's top performer this year, up more than 30%, lifted by the Iran-related surge in oil prices.
- S&P 500 industrials are up 20% year-to-date, on pace for their best year since 2019, as AI-driven capex flows deeper into the industrial base of the U.S. economy.
- The Trump administration is drafting a ban on Chinese-made data-center transceivers on security grounds, boosting American transceiver producers that connect fiber optic cables in AI infrastructure.
Why it matters: Roughly $840 billion in expected hyperscaler capex now anchors a financial flywheel whose disruption would threaten U.S. economic activity spanning chipmakers, industrial firms up 20% YTD, and corporate profits the source calls 'nutso high.' The comforting 'broadening out' narrative obscures the reality that an ever-larger share of the economy depends on a single AI investment cycle continuing to chug.
