AI Has a Power Problem Before Nvidia

GOOD MORNING, The AI trade stumbled Monday before Nvidia even reported. Nvidia fell 2.9%, Micron dropped 5.8% and Broadcom lost 2.6% as investors absorbed a new kind of risk: political resistance to the data centers that make the AI buildout possible. Texas has paused new grid connections while it audits a queue of projects whose requested power exceeds five times the state's record peak demand. At the same time, Washington launched an aggressive sanctions campaign against Iran — and oil still fell more than 2%. Markets are separating headline risk from the constraints that can actually change earnings, inflation and capital spending.

MARKETS | TLDR

Tech dragged the major indexes lower: The S&P 500 fell 0.28% to 7,652.86 and the Nasdaq lost 0.76% to 25,980.19, while the Dow gained 0.26% as financials offset weakness in semiconductors.
AI names took the pressure: Nvidia dropped 2.9%, Micron fell 5.8% and Broadcom slid 2.6%, pushing the Philadelphia Semiconductor Index lower ahead of Nvidia's Wednesday earnings report.
Oil fell despite Washington's new Iran campaign: Brent settled down 2.35% at $92.17 a barrel and WTI fell 2.35% to $85.01 as traders judged the new sanctions less threatening to near-term physical supply than a fresh military escalation.

AI INFRASTRUCTURE

The AI Trade Has a New Constraint: Permission to Plug In

Semiconductor stocks sold off Monday as a new risk entered the AI narrative. Texas Governor Greg Abbott has paused approvals for new data-center projects moving through the state's grid interconnection process while regulators audit whether proposed projects are real, funded and compatible with grid reliability. ERCOT is reviewing more than 474 gigawatts of data-center connection requests — more than five times Texas' record peak electricity demand.

That matters because AI infrastructure is no longer constrained only by chips. Data centers need land, transmission, generation capacity, water, permits and political support. If local grids begin forcing developers to prove financing and power availability before projects move forward, the bottleneck can shift upstream from GPU supply to whether a cluster can be connected at all. That directly changes the pace at which hyperscaler and AI-lab capex becomes Nvidia revenue.

The political dimension is getting harder to ignore. Wells Fargo strategist Ohsung Kwon told Reuters that increasingly hawkish rhetoric around AI and data centers is becoming a market risk ahead of the U.S. midterms. None of that means AI demand is collapsing. It means investors now have to distinguish between announced megawatts and buildable megawatts — a useful question to keep in mind when Nvidia reports Wednesday.

IRAN SANCTIONS

Washington Called It Economic D-Day. Oil Fell Anyway.

The U.S. Treasury launched "Operation Economic Outcast" on Monday, a campaign designed to sever Iran's financial connections with the rest of the world. Treasury Secretary Scott Bessent warned that countries and companies continuing to do business with Iran could face secondary sanctions and ultimately lose access to the dollar-based financial system. The administration also rolled out a new wave of Iran-related designations.

The oil market's response was strikingly calm. Brent fell $2.22 to $92.17 and WTI dropped $2.05 to $85.01. Traders had spent the previous two weeks bidding crude higher as negotiations stalled and Hormuz shipping remained constrained; Monday's reaction suggested they saw economic pressure as less immediately disruptive to barrels than another military escalation.

That distinction matters for the wider market. Iran risk becomes a bigger equity and rates problem when it removes physical oil supply and feeds inflation expectations. Sanctions can eventually do that, but Bessent did not specify which major trading partners would face penalties or when enforcement would begin. For now, Washington raised the economic threat while the oil market marked down the immediate supply shock.

HEADLINES

Nvidia considers another AI ecosystem investment: Nvidia is reportedly discussing an investment in Perplexity at a valuation above $30 billion, extending the chipmaker's role from supplier into financier and strategic backer of the companies driving AI compute demand.
Perplexity's revenue is scaling with its valuation: The startup's annualized revenue has reportedly climbed above $750 million from less than $250 million at the start of the year, giving investors another data point that some AI applications are beginning to monetize quickly.
Canada trade tensions hit U.S. autos: President Trump said tariffs on Canadian cars, trucks and auto parts would rise to 50% from January 1 after trade talks collapsed, sending Ford down 3.3%, GM down 1.1% and J.B. Hunt about 5.7% lower.
Financials quietly outperformed tech: JPMorgan gained 1.4% and Visa rose 3%, keeping the Dow positive and showing that Monday's weakness was concentrated in growth and AI exposure rather than a broad market liquidation.
Long-bond stress is still in the background: The 30-year Treasury yield remained above 5% even after Treasury announced measures aimed at containing the recent bond selloff, keeping financing costs relevant for both richly valued equities and capital-intensive AI infrastructure.

UPCOMING

PCE inflation — August 26: The Fed's preferred inflation gauge will show whether recent moderation is enough to reduce pressure for another rate hike, especially with long-term yields still elevated.
Nvidia earnings — August 26: Nvidia reports after Wednesday's close. The important questions go beyond revenue: investors will look for guidance on hyperscaler demand, supply constraints, margins and whether AI capex can keep scaling fast enough to justify today's expectations.
Marvell earnings — August 27: Marvell will provide a second read on custom accelerators, networking and data-center infrastructure — useful evidence for whether AI spending remains broad across the stack.
Kevin Warsh at Jackson Hole — August 28: With the 30-year Treasury yield still above 5%, investors will listen for how the Fed chair interprets sticky inflation, resilient growth and the recent stress in long-duration bonds.

DEEP INSIGTHS

Texas Orders a Comprehensive Data Center Audit

The governor's directive is useful because it turns an abstract AI-power debate into a concrete constraint. ERCOT is reviewing more than 474 gigawatts of proposed data-center demand, and no project in the queue can move forward until the audit verifies ownership, funding and compliance. It is a direct look at how infrastructure reality can interrupt AI capex plans.

Treasury's Operation Economic Outcast

Read the primary announcement to understand what Washington actually changed versus the rhetoric around "economic D-Day." The campaign expands pressure on Iran's financial, shipping and procurement networks and threatens secondary sanctions against foreign counterparties, but the timing and ultimate enforcement against major trading partners remain the variables that determine the market impact.
