For $10 a month, or $100 a year, you support a simple mission: spread great data visualisation wherever it comes from. You help fund the work of finding, sourcing and explaining the charts that deserve a wider audience. And you back a publication built on generosity, transparency and the belief that better understanding makes a better world.

CHART 1 • Anthropic overtook OpenAI in five months

OpenAI doubled its reported sales pace in five months and still ended up behind Anthropic. By July, Anthropic was reporting $65bn against OpenAI’s $40bn. I think the reversal is more interesting than the size of either number because it suggests that the best-known consumer brand is not automatically winning the business market.

Anthropic says much of its acceleration is coming from companies and software developers, particularly Claude Code. If you are choosing an AI supplier, that matters: the company capturing business workflows can become difficult to replace, even if another chatbot remains more famous.

I would still be careful with the apparent lead. These are annualised figures supplied by two private companies, not audited revenue calculated under one standard. They demonstrate extraordinary momentum, but not superior technology or profit. Investors discussing a possible Anthropic flotation are being asked to price that momentum before the underlying accounts are fully comparable.

Paid subscribers get access to the other four charts: Alibaba’s AI build, clinical AI, Walmart’s profit mix and record ETF flows. Together, they show why rapid adoption matters only when the economics and responsibilities survive closer inspection.
