U.S. semiconductor stocks were set to lose about $2 trillion in market value on Thursday, extending a steep selloff that had already erased $1.64 trillion over the previous six trading sessions, according to Reuters.

Marvell Technology, Microsoft and Oracle have formed a new working group under the Open Compute Project to standardize a piece of security hardware that has traditionally lived outside the server. The group, organized under the OCP Security Track, will define open specifications for an integrated hardware security module designed for cloud and hyperscale data centers.

NVIDIA and Cisco are trying to solve one of the least glamorous but most binding limits in AI data centers: the front panel of the switch. At the Open Compute Project Global Summit in Santa Clara on October 12, the two companies announced plans for Ultra-Dense Small Form Factor Pluggable, or USFP, a new optical module designed for 400 gigabits per second per lane.

Microsoft is making its biggest push yet to run its own AI services on its own silicon. The company said Monday that its newest in-house accelerator, the Maia 300, will start rolling out next year, and that it expects to install its Maia chips at multiple-gigawatt scale across its data centers. The plan would make Maia the primary inference system behind Microsoft products — the hardware that answers every Copilot prompt, summarizes every Teams meeting, and generates every research response.

At its Gemini at Work 2026 event on October 8, 2026, Google Cloud CEO Thomas Kurian introduced the Gemini agent — which Google describes as "a single, universal agent for work" that answers questions, handles knowledge work, creates media, and writes and runs code. The agent runs on the web, iOS, Android, Windows, Mac, and the command line; inside Google Workspace, Microsoft 365, and Slack; and headlessly inside third-party applications. The pitch: one interface, one API, and an objective instead of step-by-step instructions.

One of the more consequential shifts in developer infrastructure this week arrived on Friday: the entire Deno team is joining Cloudflare.

Financial terms were not disclosed.

Enterprise IT has a new supply-chain reality to reckon with. At its recent Apsara Conference, Alibaba Cloud laid out the most complete picture yet of a self-developed AI compute stack that runs from silicon to full rack-scale clusters — and it is considerably deeper than most Western observers assumed.

Two data center developers announced on October 9 that they have secured planning approval for a massive AI-ready campus in Taylor, Texas, designed to deliver up to one gigawatt of hyperscale data center capacity. The project, called the Taylor Technology Campus, is a co-development between Big Watt Digital, an integrated power and digital infrastructure platform, and PowerHouse Data Centers, a division of American Real Estate Partners focused on next-generation hyperscale facilities.
