Rene Haas has run Arm since 2022. This week he’s also become the most talked-about name in the race to replace Jensen Huang at Nvidia. Here’s who the Arm CEO is, why he’s on the list, and what it means for both companies.

Who is Rene Haas?

	Rene Haas
Current role	CEO of Arm Holdings (since February 2022)
Nvidia years	About seven years, ending in 2013
Joined Arm	2013, ran Arm’s IP Products Group before becoming CEO
Known for	Arm’s 2023 IPO and its push into data-center CPUs

Haas knows Nvidia from the inside, and at Arm he has pushed the company well beyond phones into servers and AI chips. Nvidia’s own Grace CPU is built on Arm cores, so the two companies already work closely.

The Nvidia report

On November 13, 2026 the Financial Times reported that Nvidia’s board had approached Haas about the CEO job after Huang resigned on November 12. Nvidia says it hasn’t formally engaged any candidates. It hasn’t been confirmed, and there’s no guarantee Haas is offered the job or would take it. Colette Kress is interim CEO in the meantime, and many Nvidia employees are openly asking for Huang to come back.

What it means for Arm stock

Arm’s U.S. shares closed about 5% lower on the report and have reportedly lost around 40% in a month, failing near $200. Leadership uncertainty is part of it, along with slowing revenue growth and local opposition to data centers. Losing Haas would be a blow to Arm. Getting him would reassure Nvidia shareholders who worry the company relied too much on one man.

Arm is one of the names in this side-by-side chart wall of AI data center stocks. On Nvidia’s side, Jim Cramer’s call on whether to buy the Nvidia sell-off is the loudest opinion out there, for better or worse.

Arm vs. x86 vs. custom chips

This is the bigger story behind the gossip. Arm-based CPUs are taking ground from x86 in data centers, and AI chips keep multiplying: Nvidia, AMD, Google TPU, Cerebras, Tenstorrent, Qualcomm. The latest configurator release notes list the new AI chips it can now price, and the week memory makers and AI clouds sold off together shows how tightly these chip stocks move together. To compare them yourself, try the AI Build Configurator, which prices Arm, x86 and accelerator builds side by side.

My take

Haas is the obvious outside pick: ex-Nvidia, already running a public chip company, respected by the big cloud companies. He’d be giving up a CEO job he clearly enjoys, though. I’d put the odds at a coin flip until someone confirms the talks on the record.
