The 21st Century is 25.50% complete.

[Pope Leo XIV @Pontifex]

If technology becomes the ultimate criterion, the human person risks being reduced to data, a cog in a machine or a commodity. If, however, technology is integrated with a wise perspective, it can become an instrument of growth, justice and fraternity. #MagnificaHumanitas

US and Chinese companies train almost all of the world’s most-used AI models.

(This Data Insight was written by @redouad.)

Dozens of companies worldwide develop large AI models, but it can be difficult to get a sense of where the most-used ones tend to come from.

OpenRouter is a large platform that allows users to interact with and write software on top of AI models through a single interface. It includes all the models from large companies like Google, OpenAI, Anthropic, Meta, DeepSeek, and Alibaba, as well as many, many others.

I analyzed the data published by OpenRouter on the 50 most used models each day since January 2025 and calculated the average monthly presence by origin country of the models.

As you can see on the chart, US-based companies still account for most models in OpenRouter’s top 50. But their presence has declined, and China-based companies have grown rapidly, from 5 models in the daily top 50 at the beginning of 2025 to 20 in May 2026.

Very few top-50 models come from companies outside the United States and China. Canada was represented early in 2025 by Cohere’s Command R models, while France remains represented by Mistral AI’s NeMo model.

A technology that more people use every year is, so far, almost entirely the product of two countries.

NVIDIA’s revenue from data centers and AI has grown 1,300-fold in the last 12 years—

Spending on the hardware that trains and runs artificial intelligence has grown rapidly over the past years. One of the clearest indicators of how rapidly spending has increased is the revenue of American chipmaker NVIDIA.

The company accounts for around 85% of the global market for AI chips. These are graphics processing units (GPUs), originally built for video games but well-suited to the parallel computation AI training requires.

The chart shows NVIDIA's quarterly revenue in US dollars, split by end market — sales to data-center customers (cloud providers and AI companies) in green, and sales for gaming, consumer devices, and cars in red.

In early 2014, data centers and AI accounted for just 5% of its revenue; gaming was the biggest single segment.

Twelve years later, the ratio has flipped: data centers and AI now make up over 90% of revenue. The revenue in this segment has grown 1,300-fold over the period, from $57 million to more than $75 billion per quarter.

The data centers and AI segment was already growing fast between 2014 and 2022, with revenue doubling every 16 months on average.

ChatGPT's release in late 2022, alongside the broader push to deploy AI at scale, has accelerated that pace: since then, revenue has doubled every 11 months.

@JoshHochschild Some of this was already happening, I think. People used search engines to scan the text and then write analyses about it before reading the whole doc. But AI will take this to a whole new level.

For 15 years, OGP members have worked to make it harder to hide corruption and easier to follow the money.

From Nigeria to Armenia to Canada, beneficial ownership reforms are revealing who really owns companies and profits from public contracts.
