If you thought the AI funding craze had peaked, think again. Anthropic—the startup behind Claude—just pulled off something massive: a $13 billion Series F round, giving it a jaw-dropping $183 billion valuation. That officially makes it the largest Series F round in history.

Who’s Behind the Money?

The round was led by prominent investors, including Iconiq Capital, Fidelity, and Lightspeed, with contributions from notable entities such as Qatar Investment Authority, Blackstone, and Coatue. Basically, the crème de la crème of global finance just doubled down on Anthropic.

And they’re not just throwing cash for fun—this move signals serious confidence that Anthropic can hold its ground in the brutal AI race against OpenAI, Google, and Microsoft.

Why It’s Such a Big Deal

Series F rounds usually mean a company is mature and scaling globally, not still trying to prove itself. What makes this raise stand out is:

Sheer size: $13B in one go is rare.
Sky-high valuation: $183B puts Anthropic right up there with TikTok’s parent ByteDance and some of the most valuable private companies in the world.
Insane growth: Anthropic’s annualized revenue run rate jumped from $1B to over $5B in less than a year—largely thanks to tools like Claude Code, which are catching on fast with enterprises.

How It Compares to Other Huge Rounds

Anthropic’s record-setting raise puts it in elite company:

Anthropic (2025, Series F) – Raised $13B, valued at $183B (largest Series F ever).
SpaceX (2023) – Raised $13.3B in a private round.
Databricks (2024) – Raised $10B, valuation around $62B.
OpenAI (2024) – Raised $6.6B via convertible debt, valuation around $157B.
xAI (2024, Elon Musk’s startup) – Raised $6B, valued at $24B.
ByteDance (2020, TikTok’s parent) – Raised $5B, valuation around $180B.

Clearly, the AI boom is driving some of the biggest funding rounds we’ve ever seen.

The Bigger Picture

So, what does all this mean? In short:

Investors believe AI is the bet of this generation.
Anthropic’s positioning itself as a credible rival to OpenAI and Google.
The money gives them huge firepower to push Claude deeper into enterprise, consumer apps, and maybe even new verticals we haven’t seen yet.

And let’s be honest: $13 billion isn’t just fuel—it’s rocket fuel. 🚀
