Two big-money moves in AI's industrial layer bookend the hour: a coding-startup megadeal that wires Nvidia deeper into the software stack, and an unusually candid governance essay from OpenAI itself. Poolside has struck a non-exclusive $6 billion licensing deal with Nvidia, alongside a $1 billion investment that values the AI coding startup at a $12 billion pre-money mark, according to a Newcomer report surfaced by Techmeme.

Open models just hit a symbolic milestone, Nvidia is engineering a China-compliant chip, and a new Pew study says a third of the post-ChatGPT web was written by AI. Google's Gemma family of open models has surpassed 1 billion downloads, with developers publishing more than 100,000 Gemma-derived model variants in just two years.

Nvidia is moving to take a direct financial stake in the company that already feeds its own models — a signal that the chip giant now treats training data as strategically captive as silicon. Nvidia is in talks to lead a round that would value Mercor, an AI training-data supplier, at roughly $20 billion — double the $10 billion it commanded just weeks ago.

Michael Burry, the investor who famously shorted the housing market before the 2008 crash, is now betting against Nvidia's dominance in AI chips — and he has a specific name in mind. Burry highlighted Etched, a Harvard-dropout-founded startup, as presenting "serious competition" for Nvidia in the AI inference hardware market, sending the signal that Wall Street is starting to take challengers seriously. Etched isn't vaporware.

A massive seed round just landed in the world-model space. Veeda, a new startup building world models and led by Sanja Fidler — formerly Nvidia's VP of AI Research — has raised over $90 million in seed funding from Khosla Ventures and Radical Ventures, according to The Logic. World models — systems that learn to simulate how the physical world works — have become one of the hottest frontiers in AI since NVIDIA open-sourced Cosmos 3 earlier this year.

A pair of deals and a security teardown tell the same story from different angles: the AI infrastructure stack is getting deeper, more expensive, and more contested. Google and Marvell Technology have expanded their custom silicon partnership in a deal that hands Google the right to buy up to 58.97 million Marvell shares at $206.58 each — a package worth up to $12.2 billion at full exercise.

NVIDIA is betting that the future of robotics lives at the edge, not in the cloud. At the RSS 2026 conference in Sydney, the company's physical AI team laid out detailed technical specs for Cosmos 3 — a fully open-source world foundation model that unifies text, vision, audio, and action in a single Transformer architecture. Cosmos 3 replaces the fragmented patchwork of separate vision, language, and control models with one unified system.

Beijing has quietly approved deliveries of around 10,000 Nvidia H200 chips each to ByteDance and Tencent for use at their mainland China facilities, according to people familiar with the matter who spoke to the Financial Times. The move signals a rare crack in the US export-control wall — and a calculated bet by Chinese authorities that keeping their two largest AI-driven companies supplied with cutting-edge hardware matters more than the optics of appearing to circumvent Washington's…

The lease we were waiting on is signed: OpenAI is the tenant, Nvidia is the exclusive silicon, and the site used to enrich uranium for the Cold War. OpenAI has signed a 20-year lease on SB Energy's PORTS-Pike Technology Campus in Pike County, Ohio — up to eight gigawatts of AI capacity on the decommissioned Portsmouth Gaseous Diffusion Plant, with Nvidia as the exclusive compute supplier.

Inference silicon just got a customer-led mark-up. A quant fund tested the hardware, put a rack in its own datacenter, then wrote the check. Etched said Tuesday it has raised another $700 million at a $21 billion valuation, led by Jane Street after the trading firm installed the startup's first shipped inference cluster. The company was valued at $5 billion in December and closed a $300 million Series C at $10.3 billion in July.

The AI build-out keeps slamming into a wall cash cannot move: watts. A Santa Clara chip shop just got priced like it already found a way around it. Velaura AI closed a $110 million Series A on Tuesday at a valuation of more than $1 billion, selling investors on silicon that squeezes more AI work out of the power budget they already have. Seligman Ventures led the round. Capricorn Investment Group and Prosperity7 Ventures came in as new money.
