Six months. That’s how long it took Claude Code to hit $1 billion in annual revenue.
For context, that’s faster than almost any software product in history. ChatGPT took about two years to reach that milestone. Netflix took nearly a decade.
And now Anthropic is acquiring Bun, the JavaScript runtime that makes code run faster. This isn’t just tech news. It’s a signal about where AI coding tools are headed.
The quick answer: Claude Code is the AI coding assistant that companies like Netflix, Spotify, and Salesforce use to write and debug code. Anthropic buying Bun means Claude Code is about to get faster. For non-developers, this matters because the tools that let regular people build apps (like Lovable and Cursor) run on this same infrastructure. Better foundation means better tools for everyone.
Here’s what this actually means.
What Just Happened
Two big announcements dropped on December 2nd, 2025:
First, Claude Code reached $1 billion in annual run-rate revenue. That’s just six months after launching to the public. For context, that’s faster than almost any software product in history.
Second, Anthropic announced they’re acquiring Bun, a JavaScript runtime that developers love for its speed. Bun will remain open source.
What is Claude Code?
If you’re not familiar, Claude Code is an AI coding assistant that can write, debug, and modify code. But calling it an “assistant” undersells it. It’s more like having a senior developer available 24/7 who never gets tired and can work on multiple things at once.
Companies like Netflix, Spotify, KPMG, L’Oreal, and Salesforce are using it. That’s not a list of scrappy startups. These are massive enterprises betting their development workflows on Claude Code.
The $1 billion revenue number tells you something important: this isn’t a novelty. People are paying real money because it actually works.
What is Bun?
Bun is a tool that runs JavaScript code. If that sounds technical, here’s the simple version: JavaScript is the programming language that powers most websites and apps. Bun makes JavaScript run faster.
How much faster? Significantly. Bun has over 82,000 stars on GitHub (a measure of developer popularity) and gets 7 million downloads every month. Companies like Midjourney and Lovable use it.
Bun isn’t just a runtime. It’s an all-in-one toolkit that handles package management, bundling, and testing. That means fewer tools to juggle, fewer things that can break.
Why This Acquisition Matters
Anthropic didn’t buy Bun just because it’s cool technology. They bought it because Claude Code needs to be fast.
When you ask Claude Code to write something, it doesn’t just generate text. It runs code, tests things, iterates. The faster that underlying infrastructure works, the faster you get results.
Mike Krieger, Anthropic’s Chief Product Officer, said it directly: “Bringing the Bun team into Anthropic means we can build the infrastructure to compound that momentum.”
Translation: Claude Code is about to get faster and more capable.
What This Means for Non-Developers
Here’s the part that matters if you don’t code for a living.
AI coding tools are getting good enough that regular people can build software. Not just simple stuff. Real applications. That trend is accelerating.
When Claude Code gets faster and more reliable, the barrier between “I have an idea for an app” and “I have an app” gets smaller. Tools like Lovable and Cursor are already letting non-technical people build software. Those tools often run on infrastructure like Bun.
This acquisition means the entire ecosystem gets better. Not just for professional developers, but for anyone who wants to build something.
The Bigger Picture
Claude Code hitting $1 billion in six months is a signal. AI coding tools aren’t a future thing. They’re a now thing. And they’re growing faster than almost anyone predicted.
Anthropic acquiring Bun shows they’re thinking long-term. They’re not just building AI models. They’re building the infrastructure to support those models at scale.
For you, this means: if you’ve been curious about AI coding tools but haven’t tried them yet, now’s a good time to start paying attention. The tools are getting better, faster, and more accessible every month.
