Technology shares retreated on Thursday as mounting pressures — among them higher borrowing costs and intensifying rivalry from Chinese competitors — prompted investors to reduce their exposure to artificial intelligence positions. By around 6:30 a.m. ET, contracts tied to the Nasdaq had shed roughly 1.1% of their value.

On Wednesday, the technology-weighted index recorded its steepest one-day drop since July, pulled lower by a broad retreat among chipmakers and other companies tied to artificial intelligence infrastructure. Shares of CoreWeave, the Nvidia-backed data centre operator, dropped a further 6% before the opening bell, extending a 15.5% loss recorded the previous session. Shares of Oracle slipped an additional 2% in premarket trading, a day after the stock shed nearly 9% at the close.

Pre-open trading pointed toward losses for Intel, SpaceX, and Nvidia shares. A Saxo strategist outlined in a published note how several converging headwinds had unsettled investor appetite — including questions around the rate of AI infrastructure investment, valuations that had run ahead of fundamentals, earnings from leading US frontier laboratories coming in below what markets had anticipated, mounting pressure from Chinese technology competitors, and the continued dampening effect of elevated inflation and borrowing costs. Decelerating revenue growth at both Anthropic and OpenAI was among the factors he cited as weighing on investor sentiment.

Ahead of a planned public offering, Anthropic disclosed to investors that its revenue climbed 45% to reach $17 billion over the most recent quarter, according to coverage from several news organisations. Output from second quarter figures put expansion at more than twice the rate recorded in the prior period.

During a Thursday earnings call, TSMC chief executive C.C. Wei kept his remarks to a restrained register, leading the company that holds the top position in advanced chip fabrication worldwide. Pressure on demand across parts of the market was attributed by him to a combination of higher input costs and broader economic uncertainty. The firm's stock ended the trading day 2% lower despite relatively steady earnings, a retreat that contributed to a 3.5% pullback in a Taiwan technology share index over the same stretch.

The Kospi posted the steepest losses among Asian markets at session's end, with its 7.6% retreat driven by double-digit percentage falls at SK Hynix and a 9.5% pullback at Samsung Electronics. A drop of that magnitude was enough to activate an automatic pause in exchange trading. Tokyo's Nikkei index shed nearly 5% of its value by the close, while the Hang Seng in Hong Kong retreated by around 1%.

Europe's technology-stock gauge shed around 3% in afternoon trading, with chipmaker ASML of the Netherlands accounting for some of the steepest losses at close to 5%. A higher-than-expected US inflation reading pushed up expectations for prolonged elevated borrowing costs, triggering a broad pullback in technology shares across global markets that had already absorbed an overnight downturn on Wall Street, where concerns mounted that tighter credit conditions could weigh on corporate spending tied to artificial intelligence development.

Debt loads across numerous AI firms are already considerable. Jefferies' chief European economist Mohit Kumar noted in a written analysis that any pullback in AI infrastructure investment would likely translate into a measurable deceleration in US growth forecasts. He observed that annual AI investment, measured against the size of the national economy, has reached a share of output that outpaces what railroad construction absorbed across the nineteenth century.

Prices tied to AI-related stocks swung back and forth repeatedly over the course of the year. With neither Anthropic nor OpenAI having taken their shares to a public exchange, analysts gauging appetite for AI-sector investment look elsewhere for whatever clues the market can offer.

Markets have shown repeated sensitivity to any single data point hinting at softening demand or AI infrastructure expenditure running beyond forecast. Kumar indicated that the approaching earnings season is broadly expected to show both demand levels and profitability metrics holding firm. That analyst noted Jefferies would look to reduce its exposure ahead of the midterm elections, given that a Democratic takeover of Congress was seen as a potential headwind for the sector — a view compounded by fresh competitive pressure from China, where memory chip maker CXMT reported advances in high-end semiconductor technology, prompting questions about the margin outlook for producers in the United States and South Korea.
