AMD's $8.2 Billion World Labs Deal Headlines a Sweeping Week for AI Stocks

Advanced Micro Devices agreed to acquire World Labs, the physical AI startup co-founded by Stanford professor Fei-Fei Li, in an all-stock deal valued at $8.2 billion. The acquisition is designed to give AMD a foothold in the emerging branch of AI powering autonomous machines such as robots and self-driving vehicles, and Li will join the company as executive vice president and chief scientist reporting to CEO Lisa Su. AMD shares were trading around $617 on the day, near their 52-week high, and the deal underscores the company's effort to close ground on NVIDIA despite a price-to-earnings ratio already above 159.

Micron Technology reported fourth-quarter fiscal 2026 revenue of $54.23 billion, a 379% increase compared to $11.32 billion in the same period a year earlier, driven by unprecedented demand for AI memory chips. Full-year revenue reached $133.19 billion versus $37.38 billion the prior year, with GAAP net income of $84.97 billion. Shares fell in after-hours trading as investors reacted to a heightened capital expenditure forecast that overshadowed the record results.

On the model frontier, Google launched Gemini 4 Argon, its most advanced AI model, initially releasing it to a small group of cybersecurity partners. Prediction market Polymarket placed Anthropic as the most likely holder of the best AI model by year-end 2026 at 52%, with Google at 41% and OpenAI at just 5%, reflecting the competitive reshuffling following the Gemini 4 launch.

In a separate industry flashpoint, NVIDIA CEO Jensen Huang and other AI leaders privately challenged Anthropic CEO Dario Amodei over his public warnings about the risks of frontier models. Amodei defended his stance, arguing the industry should not downplay the capabilities of the most advanced systems.

DeepSeek and Huawei jointly released open-source Ascend AI programming tools, including TileLang, a platform positioned as China's alternative to NVIDIA's CUDA software ecosystem. The move deepens ties between the two firms and signals a concerted push by China's leading AI players to reduce dependence on NVIDIA's infrastructure stack.
