📊 Data update: NVIDIA's data center & AI revenue has grown nearly 15-fold since early 2023—
Most of the chips used to train and run AI models come from NVIDIA. This makes NVIDIA's data center & AI revenue one of the clearest public figures available for tracking demand for AI hardware.
The chart here shows how the company's quarterly revenue has changed over the last eight years, split by market segment.
In early 2023, data center & AI revenue was around $4 billion per quarter. By late 2025, this had grown to $62 billion — a more than 15-fold increase in under three years.
This data comes from NVIDIA's financial reports and is not adjusted for inflation. Our colleague Veronika Samborska recently updated our chart with the latest quarterly release and will continue to do so each quarter.

In GitHub Copilot CLI, you can now leverage a multi-model reflection loop as a reviewer.
Super helpful for catching issues early before they compound.
The @GitHub Research folks released a "Rubber Duck" agent for the Copilot CLI.
Automatically get a review from a model from a different AI family.
And their data shows that yes, this does in fact help. Quite a bit.

Marc Andreessen: “The best entrepreneurs of the future will be quite skilled at 6-8 things”
Marc is asked how being a founder changes in the age of AI, to which he responds:
“I think there are two ways to have a differentiated edge in general — go deep or go broad.”
Going deep means becoming a specialized expert in your domain.
“There are domains where that really matters,” Marc explains. “In biotech and working on AI foundation models, the deeper you are the better.”
But as AI gets more powerful, Marc would bet that “going broad” will be the winning strategy for most fields. He recommends knowing a lot about many different fields and how the world works — then use AI tools to go deep whenever you need to.
“If you talk to any of the great CEOs, you see this.” Mark explains. “The really great CEOs are great at product, sales, and marketing people, they’re great legal thinkers, and they’re great at finance and with investors and the press. It’s a multidisciplinary kind of approach.”
He continues:
“The best entrepreneurs of the future will probably be quite skilled at 6 or 8 things and then will be able to cross-pollinate and combine them.”

Another first for our AI fleet... a supercomputing cluster of NVIDIA GB300s with 4600+ GPUs and featuring next gen InfiniBand.
First of many as we scale to hundreds of thousands of GB300s across our DCs, and rethink every layer of the stack across silicon, systems, and software to support next gen AI workloads.
