Anthropic raised $30 billion at a $350 billion valuation (pre-money) in February.

Google's deal from prior rounds likely lets them buy in at the same valuation other investors get every round, so they're just getting the February valuation.

Amazon did almost the same thing last week, at the same valuation.

Googles giving them something thats a lot more scares to them then dollars, large volumes of chips quickly.

If you gave anthropic 10b cash they couldn't get chips in the 0-6mo timeframe at scale. Anthropic is suffering reputational damage due to choices they have to make around capacity constraints.

Google, AWS, and Azure are the only people who can help them so they hold the cards, thus the good terms.

The GOOG and AMZN deals announced earlier this week would be considered part of the same Feb'26 round. I.e. it would have the same seniority rights as that round.

It is not uncommon to keep a round open after the formal announcement for a bit so that few investors who could not close for whatever reason are part of it. It can be hard to line up everyone at the same time, especially when they are public companies.

Specific to your point on why valuation can be lower than market at the same time - Goods(and stocks) while feel to be homogeneous, divisible, fungible, they are not. Size can value of its own.

A block of 10% shares may be worth more (or less) than unit share price, because them being available together has a property of its own, making it either more desirable when someone wants to acquire or harder to sell because there is not enough demand if all of them get dumped at the same time [1]

In this deal terms, just cause few ten millions are trading at $850B, or some investors can put in say $1-2B doesn't mean you can raise $40B at the same valuation.

There isn't depth in the market to raise $65B (including the AMZN deal) at $850B valuation. There is always some demand at any price point in the demand supply curve, you will probably find few people who will buy few shares at $10T, or $100T or some ridiculous number but that doesn't mean you can raise a large round on that.

Strictly speaking it is not even $350B per se, i.e. Google and AWS benefit from this as vendors. It very much like vendor financing with convertible debt. Meaning it is worth that much to them, but not to you and me because we are not getting some of the money back as sales that boosts are own stock.

[1] In the same vein, price can also depend on what you are getting in return, hard immediate dollars is the highest value. However if you are getting shares in return, you can usually negotiate a premium depending on risk of the shares you are getting.

The recent SpaceX - Cursor deal is a good example, any founder would likely take say $10B all cash offer over the $60B from SpaceX, or price would be closer to cash if it GOOG, AMZN, APPL shares instead - proven deeply liquid market etc.

Top of the book? Nobody on the secondary market is investing $30bn

That's the last round they raised at. They had other offers from VCs at ~850B they rejected. Seems like may have been in works since that last round was being raised and just finished paperwork?
