Citi Says Midterm Results Shift AI Money From Chips to Hyperscalers

Money is moving out of semiconductor stocks and into hyperscalers after the Democratic sweep of the US midterm elections, according to Scott Chronert, Managing Director and Head of US Equity Strategy at Citi Research. The shift reflects investor concern over increased scrutiny and possible restrictions on AI infrastructure and data centre build-outs.

Chronert said the repositioning is sentiment-driven, not a breakdown in the AI investment case. He flagged two forces at work: political risk to AI build-outs and nagging doubts about financing the massive capital expenditure the build-outs require.

Why are semiconductor stocks under pressure?

Chronert laid out the logic directly: restrictions on AI infrastructure would hurt chip suppliers first, then help the companies that already own AI compute. "It's negative initially for the semiconductor space, but then it's positive for anybody that already possesses AI compute, which is why you saw some of these hyperscalers run today," he said.

The financing concern is the second driver. Investors had questioned whether the market could fund the expected capex for AI infrastructure. On the premise that build-out slows, parts of the market where that worry was prevalent rallied, including financials and asset managers.

"What's happened here is a sentiment shift that's triggering a repositioning away from these hot spots," Chronert said, pointing to stronger action in hyperscalers and software and weaker action in semiconductors.

What does this mean for the supplier ecosystem?

Component suppliers to the AI build-out face the sharpest repricing. Chronert said markets had already priced in strong fundamental improvement for these companies in 2026 and 2027. The open debate in US markets concerned whether the capex build-out would persist into 2028 and beyond.

The election result pulled that concern forward, he said, adding a political component on top of the financing component and drawing the supplier stocks down. He still expects resolution.

"A lot of the moratorium discussion on AI and data centers, it will find resolution," Chronert said. "It might stretch out the build cycle, but it doesn't completely eliminate it."

He advised letting the dust settle on the current trade before judging those companies on fundamentals.

Which index tracks the trade?

Chronert named the Philadelphia Semiconductor Index as the key indicator for the supplier ecosystem worldwide. The Nasdaq captures less of the move because its weighting is more balanced, he said.

He also noted that a crowded "bottlenecks" trade from the second quarter had already begun to unwind before the election. Election news flow combined with the financing dynamic accelerated the disruption.

The longer-term setup remains favourable, in his view. Demand for AI compute still exceeds supply, so the supply-demand dynamics stay constructive. Even if capex moderates, he expects the market to land in a comfortable place, with legs left in the longer-term AI play.

What is the broader macro read?

Chronert described a chain he calls the triumvirate: oil prices lead inflation expectations, which lead interest rate concerns. If the Democratic sweep produces a more conciliatory approach to resolving the Iran conflict, oil prices fall. Markets priced one expected Fed rate hike out of the picture on the news, and 10-year yields came down. Lesser debt financing for AI build-outs would reinforce that move, he said.

For emerging markets such as India, he sees two benefits: lower oil prices for net importers, and reduced pressure from the Trump tariff policies of 2025 that have lingered in investor sentiment for over a year. The combination explains the broadening rally, he said, and opens the door to opportunities outside the large-cap S&P 500, including US mid-caps.

He cautioned that resolving the Iran conflict remains elusive. Citi's commodities team sees significant further downside in oil if the Strait reopens fully and logistics costs ease, even after the roughly 10% correction on the day. The firm went underweight energy going into the fourth quarter on that basis. Markets now price two additional Fed hikes through next fall, down from three, but Chronert said the fundamental influence of these shifts remains months ahead.
