Bill Baruch Buys Arm, Cites AI Chip Pivot and Meta Deal

Executive Signal Summary

Investor Bill Baruch said he has bought shares of Arm Holdings, citing the company's pivot to building physical in‑house AI chips and a recent deal with Meta as key catalysts. Arm — historically a licensing firm for chip architectures — has begun making its own chips, naming Meta as its first official customer and listing other committed customers including OpenAI, SAP and Cloudflare. CEO Rene Haas told investors the newly released chip is expected to generate roughly $15 billion in annual revenue by 2031; Arm shares jumped about 16% on the announcement and have risen roughly 89% year‑to‑date. Baruch, founder and president of Blue Line Capital, also added to his position in Entegris, a semiconductor materials supplier whose stock has climbed about 73% this year.

Arm Forecasts $15B Revenue from New AGI CPU

Arm Holdings unveiled its first in‑house server chip, the AGI CPU, at an event in San Francisco and said the chip — designed for AI inference in data centers — will generate $15 billion in revenue by 2031. Arm expects total annual revenue of $25 billion and EPS of $9 by 2031, a material increase from its roughly $4 billion revenue in 2025. The move marks a strategic shift from Arm’s traditional IP licensing model to selling hardware and competing with some licensees. Meta is the first announced customer; OpenAI, Cloudflare and SAP are also early customers. Arm said the chip is being sold at about a 50% gross margin. Citi analysts called the announcement the company’s most significant shift in history, and Arm’s stock jumped on the news.

Arm CEO Confident $2B AI CPU Revenue Goal Achievable

Arm Holdings CEO Rene Haas told CNBC's Jim Cramer on September 16, 2026, that the company is increasingly confident it can meet Wall Street's $2 billion revenue target for its new in-house data center CPU, the AGI CPU. The demand for the chip has been strong, but investors have focused on Arm's ability to secure sufficient manufacturing capacity to convert that demand into revenue. Haas noted that confidence in achieving the $2 billion figure has grown from May to July and further strengthened by September. The AGI CPU marks a significant expansion of Arm's business model, moving from licensing chip designs to selling complete chips. Arm first disclosed $2 billion in demand in May, double its initial $1 billion outlook, but maintained a conservative official outlook until supply confidence improved. Shares have declined about 45% from their June high after a parabolic run earlier in the year.

Arm Launches First In‑House AGI CPU; Meta Debut Customer

Arm unveiled its first in-house data-center CPU (the Arm AGI CPU) at a San Francisco event where Meta was announced as the initial customer. CEO Rene Haas projected the new chip could generate roughly $15 billion in annual revenue by 2031 and said Arm expects total annual revenue of $25 billion and EPS of $9 by that year. The announcement sent Arm shares up about 6% in after-hours trading. Arm built a dedicated chip lab in Austin to develop the CPU and plans production later in 2026 (fabrication details have been reported elsewhere). CFO Jason Child said the chip is being sold at roughly a 50% gross profit. Haas tied stronger CPU demand to the rise of agentic AI, signaling a strategic move from pure IP licensing into chip sales and broader AI infrastructure competition.
