TradingKey - As AI data center investment continues to grow, both AMD (AMD) and Broadcom (AVGO) have emerged as key AI chip plays alongside Nvidia (NVDA), but the two companies have distinct business models. AMD primarily competes in the general-purpose AI computing market through its Instinct GPUs, EPYC server CPUs, and Helios rack systems, while Broadcom focuses on developing custom AI accelerators (ASIC/XPU) for major clients such as Google (GOOGL), OpenAI, and Anthropic, alongside high-speed networking chips.

On September 24, Eastern Time, Meta Platforms (META) reached an intraday price of $777.89, hitting a nearly one-year high.

The core reason is that the monetization path for Muse is becoming increasingly clear, leaving the bank more optimistic about Meta's growth potential beyond advertising.
