Today, Valar Atomics became the first startup in history to split the atom.

Announcing Project Nova, a series of zero power critical tests on Valar Atomics' Nova Core in collaboration with Los Alamos NCERC and NNSS.

Nova went critical for the first time this morning at 11:45am. The Nova core is a subset of our Ward250 core, using the same moderator, fuel, and reactivity control. Taking Nova critical gives us real-world data about the characteristics of our geometry and control scheme, and allows us to test our models and simulations against reality.

Today we're announcing Valar Atomics' $130m Series A, led by Doug Philippone at Snowpoint Ventures and co-lead by Day One and Dream.

Also joining Team Valar are Balerion, Contrary, DTX, Alumni, Crosscut, Triplepoint, Palmer Luckey, Shyam Sankar, and more great funds and angels. Image Doug Philippone brings decades of experience as an investor and operator, from Army Rangers and JSOC Commander to Head of Global Defense at Palantir, and most recently co-founder and GP at Snowpoint.

We're thrilled to welcome Doug to our board of directors.

Valar Atomics is honored to announce that we've been selected by the Department of Energy to achieve criticality on American soil by July 4th, 2026, pursuant to Executive Order 14301.

We're grateful to President Trump and Secretary Wright for their leadership in this matter. 1/x Image Today, America embarks on a second Manhattan Project. This time, we seek to unlock the atom for energy, intelligence, and industrial might. But we must work with the same fervor and tenacity as our forebears to accomplish the President’s ambitious goal.

A Roadmap for the American Nuclear Golden Age

Today, President Trump established a new policy for nuclear energy which represents a fundamental shift from the last 45 years of stagnation. This shift is codified in four executive orders.

Let's dig in! Image First the history. The United States was once the undisputed leader in atomic energy. We created the world’s first reactor, and piloted every major reactor architecture since, from LWRs to to molten salt to my own favorite, the HTGR.

It took about 10 years to get to Valar Atomics. I began pursuing this question in earnest when I was 14. In 2 years I had an idea of the problem, which I still believe. But it took 8 more years to build an accurate mental model of the industry and of reality, then find a solution The process generally looked like:

1. Describe my mental model in writing
2. Make specific predictions about what I expect to find in reality
2. Spend a few months Googling, reading, and talking to people with experience
3. Figure out why my predictions were wrong
4. Repeat

This morning Samo Burja went on a podcast with some very hard words for nuclear energy. I want address them immediately. But not because he's wrong.

Instead, because he got a few CRUCIAL things right; and the hard truths he tells go to the core of why I started Valar Atomics. Burja argues two things:

1. Energy demand is unexpectedly low.
2. In order to make anything cheap, you need to make thousands of it. Nuclear is too powerful and energy demand too anemic to justify thousands of reactors. There's no market!

(he's right; I'll get to that shortly)

Today I'm excited to unveil Valar Atomics!

Valar is my master plan to make energy 10x cheaper in 10 years by pulling oil and gas out of thin air with nuclear fission.

This will untether energy from climate and politics, fuel American industry, and unlock a new era of growth Image All of our greatest ambitions — interplanetary life, artificial intelligence, robotics, and biotech — need energy that is orders of magnitude cheaper and more abundant than we have now.

In 1970 we stopped our century-long march of making energy cheaper.

I'm here to restart it. Image

Any examples of this @cramforce? docs mention the possibility as well, but attempts have failed. I need sls here rather than edge because @LangChainAI doesn't support Edge Runtime yet; stuck btwn rock and hard place: no streaming on sls, no Langchain on edge 😵‍💫 @cramforce @LangChainAI Here it is in docs as well; goes on to talk about ReadableStream response on edge, but highjacking the response on serverless does not work vercel.com/docs/framework… Image
