AI Disruption Fears Spark Selloff; Novo Nordisk, AMD Drops After Earnings | Bloomberg Brief 2/4/2026

Global markets sold off amid fears of AI-driven disruption after Anthropic’s new automation tool, with software stocks plunging and major companies like AMD and Novo Nordisk dropping sharply on disappointing earnings and forecasts. Meanwhile, investors are becoming more selective in the AI sector, while geopolitical tensions and mixed corporate results add to market volatility.

Global equity markets continued their selloff, driven largely by fears of artificial intelligence (AI) disruption following Anthropic’s launch of a new AI automation tool. This tool, with the potential to upend industries such as software, financial services, and asset management, triggered a sharp decline in software stocks and their funders, erasing most of the Nasdaq 100’s gains for the year. In contrast, the Russell 2000 index remained resilient, buoyed by expectations around Federal Reserve policy. Meanwhile, gold prices continued to rise, and Bitcoin struggled to find support, with some analysts questioning its status as a speculative asset.

Earnings season brought mixed results. AMD disappointed investors with a sales forecast that fell short of expectations, raising concerns about its ability to compete with Nvidia in the AI chip space. Super Micro Computer, however, saw a significant boost due to strong demand for its AI server products. Novo Nordisk shares plunged 20% in Copenhagen after the company forecast a steep sales decline in 2026, citing pricing pressures on its GLP-1 weight loss drugs. The company’s CEO expressed confidence in future volume growth, but investors were unsettled by the speed and magnitude of the anticipated price declines.

The AI sector’s volatility was further highlighted by reports of Nvidia considering a $20 billion investment in OpenAI, alongside potential funding from Amazon and Salesforce. This move is seen as a strategic hedge for Nvidia, ensuring continued demand for its chips as AI models proliferate. Market analysts emphasized that investors must now be more selective, as not all AI-related companies will emerge as winners. The indiscriminate buying of AI stocks has given way to a more cautious approach, with a focus on differentiating between likely beneficiaries and those at risk of disruption.

In Europe, UBS reported strong fourth-quarter earnings and announced a $3 billion buyback for 2026, despite ongoing challenges integrating Credit Suisse and meeting new capital requirements. Santander shares dropped after acquiring Webster Financial, marking the largest decline since October. Meanwhile, the Federal Reserve saw Governor Stephen Miran step down from his White House role, and President Trump signed a funding deal to end a partial government shutdown, though the Department of Homeland Security’s funding remains unresolved.

On the geopolitical front, Iran requested that upcoming nuclear talks with the U.S. be moved from Turkey to Oman and focus solely on nuclear issues, resisting broader discussions on ballistic missiles and regional proxies. This shift adds uncertainty to already tense U.S.-Iran relations. In U.S. politics, the House canceled a contempt vote against Bill and Hillary Clinton after they agreed to testify on their ties to Jeffrey Epstein. Market participants are now closely watching upcoming earnings from Alphabet and Qualcomm, as well as macroeconomic data releases, to gauge the next direction for equities amid ongoing volatility.
