How Rich Will Anthropic's Founders Get Off The IPO?

Reading time: 5m 25s

The biggest IPO in the history of markets is upon us; you’ve probably seen everyone dive into everything from the number breakdowns and the company structure to projections, valuation models, and all the other boring things. 

We like to do things a bit differently. We’d like to know how much cash money moolah each of the founders will be walking away with after this IPO. 

Spoiler alert: BILLIONS will be made. 

Let’s dive into just how rich our future A overlords are going to be. 

Note that a lot of relevant information is still not publicly available, so most of this is speculation based on the information available, but it should give you a close enough estimate. 

The structure

Before we dive into the fun details, we must first understand the general corporate structure. 

Anthropic has seven co-founders, and their shares are divided as follows:

As you can see, the equity is distributed pretty evenly among the seven co-founders. However, these 1.7 billion cumulative shares come under the “beneficial ownership” umbrella, which has a very broad description under SEC rules. They can include: 

• Shares owned by an individual 
• Shares held through trusts over which the individual exercises voting or investment control 
• Stock options exercisable within 60 days
• Restricted Stock Units (RSUs) 

So if we dive deeper into the individual breakdown, things look a bit different. Specifically, Dario and Daniela Amodei have a more intricate breakdown than the rest.

In the most recent November 10th amendment of the filing, a lot more details were revealed about share distribution, IPO pricing, and so on. 

So let’s get into the fun bit. 

How rich will they get? 

Although not a confirmed number, the amendment said they expect an IPO price between $70-$78. So rather than boring you with complex math on what the actual number could be, we’re just going to use $74 midpoint as the expected price. 

Another thing to keep note of is the actual distribution of shares. 

But this will be relevant later on.

Initially, each founder has disclosed that they will be selling approximately 1.39% of their shares. So what does that look like? 

So each founder is confirmed to be taking around $250 million off the table to begin with; that’s a healthy chunk of change. But they will all still have a little over 98% of their shares in hand, distributed, as we said earlier, among different trusts or vehicles. 

So what would their net worth be? 

Yeah, when I first ran the numbers, I just looked at it thinking, why’d I try to be the funny guy in school? Mind you, this is after the initial $250 million. 

One IPO will mint SEVEN new multi-billionaires. Even on the conservative end of the spectrum, $16 billion. SIXTEEN BILLION. I can’t do anything other than stand up and applaud. Talk about a handsome payday. 

One caveat to keep note of is that some founders have already sold some shares. 

As most of you already know, Anthropic has done multiple previous funding rounds. It was in these rounds that existing shareholders, including Dario and Daniela Amodei, sold a portion of their shares. 

Here’s what we know based on what’s publicly available. 

A funding round in June 2025 saw 27.9 million shares tendered at a price of $5.61. The funding round in April 2026 saw 179.8 million shares tendered at a price of $25.9. 

Over these two rounds, around $4.7 billion worth of shares changed hands. Although specifics are not available, the sellers in the rounds included Dario Amodei, Daniela Amodei, Krishna Rao (Anthropic CFO), and Holden Karnofsky (Daniela’s spouse). 

So it’s safe to assume that a few of them have already made a couple of hundred million. 

The money just keeps flowing in. 

Other important bits 

So, we have the headline numbers on just how rich they will get, but I think there are some other interesting bits surrounding governance and control that are worth knowing. 

Anthropic’s corporate governance structure is somewhat unique. It’s divided into three categories: 

• Founder LLC 
• Long-term Benefit Trust (LTBT) 
• Public shareholders 

The Founder LLC holds one Class F share, and the LTBT holds one Class T share. There are a bunch of other classes such as A, N, E, and so on that all mean different things, but the details about the class don’t matter here. 

What is relevant is the control. 

The Founder LLC has seven members, all of whom are co-founders. The special class F shares that this LLC holds give them 50.1% voting power over all shareholder matters. 

The class T shares from the LTBT give the founders authority to elect and remove class T directors, and the class T directors comprise the majority of the authorized board. 

So why is this relevant? 

If you take into account the shares held by the individual founders, their combined economic power in terms of equity is 13.67%, while the other 86.33% of economic power is made up of public shareholders, other investors, strategic partners, and so on. 

So, despite not having that much economic power, the founders still retain full control over governance and all decisions that the company takes going forward. 

So the situation is that regardless of how many shares a non-founder holds, they will never have influence over decision-making; shareholders simply have economic exposure to Anthropic while the founders retain full control over the board and general company decisions. Probably for the better. 

Concluding thoughts 

The gist of the matter is that the seven co-founders have built a brilliant product, and this product has now made them billions of dollars. 

When it comes to the investment angle, we have no advice to give. The fact that founders will be up so much should not be construed as a bearish thing, as they won’t be able to sell it all instantly. 

They’ve also stated that all the founders have pledged 80% of their equity together to philanthropic causes. I’m sure there’s a little reading between the lines to do here, but the fact of the matter is that only a small percentage is likely to be sold by the founders. 

Whether this makes Anthropic a good or bad investment is up to you to decide because, honestly, I have no idea either. What I can say with certainty after seeing these numbers is… 

I wish that were me.
