The Neocloud Boom

From Clouded Judgement: The Neocloud Boom

\\ Caveat — This post is not a recommendation on current Neocloud stocks, or commentary on their valuation, but instead some personal observations on the market as a whole \\

A Neocloud boom feels inevitable. Clicking out one layer, the data center infrastructure buildout feels like it could turn into one of the largest wealth creation moments ever in physical infrastructure. Now that I’ve spoken in absolutes like this, we can bookmark this post for later when we look back on “signs of the top” :)

Let me caveat this post with the fact that I’m very AGI pilled. Just about any estimate for “tokens consumed by X date” or model progress or data centers built or total demand I’m taking the over.

In all seriousness, the numbers are staggering. Rumors / reports peg Anthropic / OpenAI at ~3-3.5GW of capacity to end 2025. OpenAI has talked about getting to 30GW by 2030. Let’s assume Anthropic has similar plans. Just those two alone will bring on (or plan to bring on) ~55GW over the next ~4.5 years. Now let’s assume OpenAI / Anthropic represent 30-40% of the new builds over the coming 4.5 years (I asked Claude for its best guess on this figure, I have no more specific insights here other than Claude’s estimation). That’s >150GW of new capacity in the next 4.5 years alone.

Ballpark figures are ~$50b total costs to build 1GW. For a Blackwell dominated data center, that roughly breaks down into:

• ~70% for chips / compute. 50% GPUs 10% networking 5% CPUs 3% Storage 2% assembly
• ~20% for data center shell + power infra (substations, transformers, switchgear, backup generators, hv interconnect, etc)
• ~5% cooling
• ~5% land, permitting, and other costs

So in total, ~$50b for a 1GW build, multiplied by 150GW = $7.5Tn total spend. Spread across 4.5 years that’s ~$1.7Tn / year, or ~5% of annual US GDP (~$32Tn / year). I asked Claude to come up with some historical precedents to put this in perspective:

• US Railroad building out in the 1880s was ~6% of GDP
• Telcom building in early 2000’s was ~1.2% of GDP
• The Manhattan Project was ~0.4% of GDP

So this “AI Buildout” is high, but not as high as the railroad buildout.

So that’s the costs - $7.5Tn over 4.5 years. Someone is going to make a ton of money financing all of that.

But how about the revenue / enterprise value creation serving all of it. This is where neoclouds come in. Here’s a quick scorecard on 3 public neoclouds today: Coreweave, Nebius and IREN

Source: Claude

This is a totally made up multiple, but Coreweave / IREN are both at ~$90b of enterprise value per live GW. Nebius quite a bit higher (again, not a comment on valuation, just doing some fun math).

Let’s say the Coreweave / Nebius “math” holds for rest of industry and $90b of enterprise value is created for every deployed GW. If we’re going to bring ~150GW online in next 4.5 years, that equates to $13.5Tn of enterprise value creation…Again, this is all funny math…Lots of that build will be done by hyperscalers, a lot of it for their own internal consumption vs to sell to others. But the numbers are wild!

Even if you assume only ~20% is captured by Neoclouds, that’s over $2.5Tn of enterprise value created in the next 4.5 years. The numbers are so big, it can’t be served by only a few players. The only natural explanation is that we’ll see a boom in Neoclouds, hence the title of this post. In a few years I bet there will be a handful of very large Neoclouds, and then a long tail (including independently owned single site neoclouds, similar to how the IPP (independent power providers) market played out. Expect PE to play a big role!

Obviously you could say my initial assumption is BS - that we’re not going to bring online another 150GW by 2030. Either because you don’t believe AI will garner that demand (but I’ll point you to my initial caveat! I’m very AI pilled…). or you think the costs are just too high as a percent of GDP. But let’s dream the dream - this could be a MASSIVE opportunity…And as far as the venture communities go, there is still a lot of skepticism around neoclouds (I’d ask them, who else is going to build out the compute for AGI!). In many ways, Neoclouds are the perfect hedge on a venture portfolio :) If everything else goes to zero because AGI captured all the value, someone will have to build, deliver, and serve that compute :)

Ok last little bit here. I was done writing the post, but thought I couldn’t write a post about Neoclouds and not bring up SpaceX. SpaceX? How are they a Neocloud? I’m sure most of the readers of this blog have been plugged into the AI news cycle, but in case not, here’s a quick summary. xAI was a AI lab Elon founded. They created two very large data centers of their own. Colossus 1 (which is estimated at ~300MW), and Colossus 2 (which has total capacity of 2GW, but estimates peg it at ~500MW operational today). SpaceX then bought xAI. They then proceeded to “rent” capacity at Colossus 1 and Colossus 2 to Anthropic! In the SpaceX S-1, they gave some details on this commercial relationship.

According to the S-1, Anthropic is paying SpaceX $15b per year (!) for this capacity. They supposedly have all of the capacity in Colossus 1 (~300MW). Impossible to know how much of Colossus 2 they have, but let’s assume it’s ~40%? That would give them an incremental ~200MW. SpaceX/xAI has to keep some for itself…and Cursor has announced they have some of that capacity (which Elon as agreed to buy as well…are you keeping up with all the acquisitions??).

So that’s $15b / year for ~500MW. To put those numbers in perspective:

• SpaceX did $18.7b of revenue in the full year 2025. And they just “created” a new business line item of ~$15b in an instant! Insane. SpaceX was founded in 2002. It took them 23 years to get to an annual revenue figure of ~$19b. And with their new “neocloud” they generated almost that same amount. The opportunity for Neoclouds is massive!
• This math also assumes Anthropic is paying ~$30m / MW ($15,000M / 500MW). That would be really high…Most neocloud comps are closer to the $10-$12m / MW. Coreweave guided to ~$18.5b annualized run rate revenue to end 2026, and said they’re “on track to reach or exceed our target of more than 1.7GW by the end of 2026.” This math comes out to ~$11m / MW. If Anthropic was paying $11m / MW that would mean they have ~1.4GW of capacity from SpaceX (which isn’t possible).

The $30m / MW does feel high…BUT - the contract has a 90 day out. Anyone can cancel the deal with a 90 day warning. And Anthropic is VERY compute constrained. So might they stretch on a one time deal with an out? Maybe!

Either way - I’m bulled up on the opportunity for Neoclouds :) The revenue potential is clearly massive. Now they just need to prove they can make the business model work! On revenue multiples, CoreWeave trades at ~6x NTM rev, Nebius / IREN at ~10x. On NTM EBITDA, CoreWeave is trading ~10x, with IREN / Nebius ~20x.

I believe trillions of enterprise value will be created in the neocloud space in the next 5+ years. Go grab it! I may write a piece next week that discusses why these businesses could really explode if the chips retain value after years 4-5.
