GAVIN BAKER: “A month ago, SpaceX did not have a cloud computing business. Now by some measures, it is the fourth largest cloud ahead of Oracle — and they did that in 1 month. Let's see what they do in a year. “A really important variable for SpaceX is...

A single gigawatt of orbital compute requires roughly 200 Starship launches and Elon Musk is not satisfied with gigawatts (Save this). The target is 100 gigawatts of orbital compute per year which means SpaceX is staring down a launch requirement that no organization in human history has ever attempted at anything close to that scale. He acknowledges that scaling to gigawatts per year in orbit is a very hard challenge, but then points to something most people have missed entirely, SpaceX has already demonstrated the foundational capability, because building and launching thousands of Starlink satellites per year is the same industrial problem applied to a different payload. When you understand the orbital compute satellite as a larger version of Starlink V3 with an Nvidia GPU rack at the center instead of a communications payload, the manufacturing and launch scaling challenge stops looking like science fiction and starts looking like a production ramp. The infrastructure to support that ramp is already being built. SpaceX is currently capacitizing for thousands of launches per year, two launch towers and pads in South Texas are operational, the first pad at Cape Canaveral is nearly complete, a second is on the way at Launch Complex 37, and additional locations are already in discussion. As the CFO says it "You need to have those cost curves as you ramp up in volume and time, your costs go down." The vision he describes for what this eventually enables is striking in its specificity. He imagines asking Grok a question on his phone, the inference running on an orbital compute satellite, and the answer coming back down through Starlink direct-to-cell, a complete AI query processed entirely in space, from prompt to response, without touching a single terrestrial data center. That moment, he says, is closer than the industry thinks, with initial capability demonstrations possible as soon as next year. The bottleneck that stands between now and that moment is not the satellite design, the cooling physics, or the silicon, all of which SpaceX has already worked through.

The Rapid Growth of SpaceX, Starlink, Starshield & Armada: “I am very grateful that SpaceX is an American company.” "Data centers in space is coming, & it makes sense" “5 years ago they hadn’t even launched Starlink—now it’s in 150 countries & it’s continuing to grow every week.” “It’s an unfair advantage that we have with Starshield.” “If the world can get access to SpaceX, I think that’s a good thing.” Dan Wright (Dan Wright), CEO of Armada Elon (Elon Musk) builds long-term advantage, then unleashes it at massive scale: SpaceX, Starlink, Tesla, Neuralink, xAI.. . . . "We started the company working with SpaceX & they’ve continued to be a great partner for us. What that means is that as SpaceX rolls out throughout the world—& most people don’t know 5 years ago they hadn’t even launched Starlink —it’s in 150 countries & it’s continuing to grow every week. We are the first mover when it comes to the infrastructure, & that partnership works really well because we complement the connectivity with the infrastructure & the AI. We always are at the edge. It’s funny, I get messages from our team all the time & it’s like the most crazy places you can imagine. And the edge is gonna continue to get redefined. I get calls literally—I was on the call with somebody and they’re like, “Hey, can we get one of these in Antarctica?” I’m like, “Well yeah, Starlink’s live in Antarctica. No reason why we can’t do that.” Obviously data center in space is the new hotness. Everybody’s talking about it." "Yeah, what’s the deal with that—so are you gonna get these in space?" :They are modular. I mean the edge is continuing—this is actually a debate that we have in terms of how soon it’s going to happen—but it’s definitely going to happen. Data centers in space is coming, and it makes sense, right? If you think about what SpaceX is talking about with Starship going to the moon—you’re going to need compute, especially as you start to think about Optimus robots building bases on the moon, later Mars. You’re going to need large amounts of compute. Not to mention a lot of the things that we do here on Earth, you’re gonna want to do there in space. And it’s a lot more efficient to do it, especially in hostile environments, if you can automate more of that—things like mining, for example. And so you’re gonna see data centers in space, and I’m sure we’re definitely gonna be a part of it. "What do you think about SpaceX’s rumored IPO for 2026?" "I mean, I think SpaceX is an incredible company and they have a ton of value. So I don’t have any insider information here—but I would say, hey, if the world can get access to SpaceX, I think that’s a good thing. Starlink is really amazing in the sense that it just continues to get better so fast. They’re rolling out in new countries every week in major markets. Just as a real recent example, just this last week they launched in South Korea—big market and an important ally for the US, so that’s a big deal. They’re also expanding the types of services that are available. It started as a consumer product, then they brought it to enterprise. Initially that was used more as a backup, and now it’s being used more as a primary—and that is because the service keeps getting better and better as more satellites go up into the sky. Each generation of satellite is also better, not to mention the terminals on the ground. There’s now multiple types of terminals, including the more recent minis that people really like—“Hey, I can put it in a backpack if I go on a hike or if I’m traveling. I can put it on the ski rack of my car.” Perfect internet all the time. All that does for us is it gives us more use cases that we can unlock. Now that you have connectivity on the oil rig, or on a farm, or a ranch—wherever you are—we can apply the AI to those situations on the ground without latency, and then send the metadata back to some other location that they want it. Part of the full-stack approach. And also with Starshield—that’s a huge advantage when you think about some of the conflicts that are going on. People talk to me a lot about this race with China and the geopolitical conflicts around the world. I am very grateful that SpaceX is an American company. I feel like it’s an unfair advantage that we have with Starshield available to the DoD. We want to be the first mover with the infrastructure and the AI to help solve problems at the edge, and the work we’re doing with the Navy is a good example of that."

Elon Musk just explained why the SpaceX IPO is an energy story and the energy constraint is why he believes space becomes the only viable path for AI to scale (Save this). The argument he is making is one of the most important and least understood things happening in technology right now. The United States currently consumes roughly 500 gigawatts of electricity on average. To double that capacity which is what continued AI expansion on the current terrestrial trajectory would eventually require would mean building as many power plants as currently exist in the entire country. He is not arguing that this is technically impossible, just that communities are not willing to accept it, that permitting timelines make it unrealistic, and that the hard ceiling on Earth based power generation means the expansion of AI compute will eventually hit a wall that no amount of capital can overcome on the ground. His observation is that in space, that wall does not exist. A solar panel in orbit produces roughly five times more power than the same panel on Earth, operates in continuous sunlight uninterrupted by weather or nighttime, and benefits from the vacuum of space as a completely passive cooling system meaning the two largest operating costs of any terrestrial data center, energy and cooling, are effectively eliminated. He then said that you could theoretically increase harnessed energy by a factor of one million and still be using less than a millionth of the sun's total energy output. This is the underlying physics of why SpaceX filed with the FCC to launch up to one million solar powered AI satellites, and why they described that constellation in their own filing as a first step toward becoming a Kardashev Type II civilization capable of harnessing the full power of the sun. To understand what makes this credible rather than visionary, you need to understand what SpaceX already controls that no other company on earth possesses. Starship, once operating at full cadence, can deliver 100 to 150 tons of payload to orbit per launch, at a target cost per kilogram that is an order of magnitude lower than any existing vehicle. Musk's stated ambition is to scale Starship to 10,000 to 30,000 launches per year, a frequency that would allow the deployment of orbital compute infrastructure at a pace that is currently unimaginable with any existing rocket. He told xAI staff earlier this year that achieving space-based AI at scale will eventually require manufacturing facilities on the moon, building solar panels and heat dissipation structures from lunar silicon and aluminum, and launching them into orbit from there rather than from Earth's surface because the moon's lower gravity makes the economics of launch dramatically more favorable. SpaceX's S-1 filing explicitly states that its launch capabilities could enable massive AI compute satellite constellations with the potential for millions of satellites for orbital data centers, with the first launch potentially occurring as soon as 2028. Google and Alphabet are already in advanced talks with SpaceX about deploying space-based data centers. Starcloud, a startup running Nvidia H100 GPUs in orbit, has already validated that high-performance AI inference workloads can operate in space, with plans to scale to five gigawatts of orbital compute power by 2035. This is why Musk believes the cost crossover happens in two to three years because SpaceX's launch cost trajectory intersects with the accelerating energy constraint on the ground in a way that makes space genuinely cheaper, faster, and less regulated at exactly the moment AI demand is hitting its hardest physical limits.

In our last conversation, Gavin said data centers in space will be the most important thing in 3-4 years. He explains that means "racks in space" and thinks orbital compute will solve the watts shortage: "When people hear data centers in space, they picture a Pentagon-sized building in space. That's not what it is. A Blackwell rack weighs 3,000 pounds. It's eight feet high. Four feet deep. Three feet wide. It's racks in space. It has these solar wings that are probably 500 feet long on each side. You keep it in a Sun-synchronous orbit, so those solar panels are always in the sun. And then because it's in an exactly Sun-synchronous orbit, the radiator, which extends behind it for hundreds of feet is in the shade. You link these racks using lasers traveling through vacuum which are already on every Starlink. SpaceX operates the world's largest satellite fleet, which is 98 or 99% of all satellites in orbit. Every Starlink, they're cooling it today. I think Starlink V3 is going to operate at 20 kilowatts. A Blackwell rack is only 100 kilowatts. And people talk a lot about density. Well, if you're connecting the racks with lasers through vacuum, you can make the rack bigger physically. In space, there's all sorts of things that SpaceX can do. They also now operate the largest data center on Earth. I've spent a lot of time at Starbase over the years, and I've talked to a lot of SpaceX engineers. It is the most talented group of engineers on planet Earth, and they're very confident they have solved this."
