Lead Story#

A temporary pause in U.S.-Iran hostilities sent oil prices tumbling and buoyed equity markets, but the tech sector remains heavily scrutinized as investors weigh the spiraling capital expenditure costs of the AI arms race.

Markets & Economics#

Crude oil reversed its recent surge following a halt in the Middle East conflict, with U.S. West Texas Intermediate futures sliding 5.34% to $84.55 and global benchmark Brent crude falling 5.77% to $91.20. The drop in energy prices pulled the 10-year Treasury yield down more than 3 basis points to 4.64%. Markets are now pivoting to Wednesday’s Federal Open Market Committee meeting, where investors expect Fed Chair Kevin Warsh to hold the benchmark interest rate steady between 3.5% and 3.75%. Overseas, the Monetary Authority of Singapore preemptively tightened policy against inflation risks, while China’s industrial profit growth slowed to 15.1% in June amid lagging domestic demand.

Business & Earnings#

Nvidia is reportedly in talks to provide a massive $250 billion backstop to help OpenAI finance a 10-gigawatt AI data center campus in Ohio. As AI infrastructure spending rattles investors, Apple reclaimed the title of the world’s most valuable company from Nvidia, hitting a $4.95 trillion market cap ahead of its Thursday earnings report. In the automotive sector, Porsche announced it will slash 9,000 jobs by 2035 to cut costs as it struggles with weak EV demand and a collapsing Chinese market. Meanwhile, NBCUniversal inked a multiyear deal to embed its Peacock streaming service and live sports directly into YouTube Premium for U.S. subscribers.

Investing & Commentary#

“Big Short” investor Steve Eisman revealed he sold his long-time Alphabet stake to reduce AI exposure, warning that the market is overly concentrated in a single trade and faces a massive correction if AI underdelivers. Jim Cramer echoed these concerns, explicitly warning investors to exit margin positions on data center stocks as the circular financing deals between Nvidia and OpenAI strongly parallel the excesses of the dot-com bubble. Elsewhere, Piper Sandler upgraded Rivian to Overweight with a $20 price target, arguing the EV maker’s vertical integration positions it as a major winner in the emerging robotaxi market.
