Former world's first trillionaire
Sure would be nice to have some food, affordable housing, and healthcare…
Get out of here, fracking lazy SOCIALIST!! 😡
Down 6%.
The line wiggled a bit.
I think you mean PLUNGED or DECIMATED!
/s
Also I’m sick of these words in titles. As you said it’s barely a ripple overall.
Once again, wealth trickles up to the billionaires.
Capitalism! Gotta love it, or not.
I got my stupid 111€ profit from the stupid shares after selling it off.
Hope it dies in a fire.
I choose 'not'
I get it. I have a uniquely shaped rock that I found in a ditch. I value that thing at about 530 billion dollars. /s
Does it repel tigers?
Only under water
I will buy this rock.
The reflecting pool is now full of underwater tigers tasked with stalking the algae. The price has quadrupled.
Absolutely!!
Money isn't real.
SpaceX on Tuesday disclosed it would acquire Cursor for $60 billion in stock, representing roughly 3.4% dilution—meaning investor stakes will represent a smaller percentage of the company—of SpaceX’s $1.77 trillion IPO valuation.
I never understood this. Dilution should require a vote from owners.
You vote by selling your stock if you disagree.
Are more than 50% of shares not owned by Musk? If not, a vote wouldn't even matter.
What about indication of change? I.E. ability to sell before dilution.

The valuation of the stock is based on Musk doing what he's always done, which is making seemingly impossible promises sometime in the future.
You know what he promised by 2025? A fleet of driverless Tesla taxis. xAI producing the first AGI. A human being on Mars planting a flag.
You know what the evaluation of SpaceX is based on? The promise of a Mars colony with one million human inhabitants, and space-based data centers. It's going to be decades before it's worth the IPO, if ever.
In the meantime SpaceX is in debt 20 billion, and is bleeding money. It lost $4.94 billion in 2025.
So it looks to me like a private equity project. Like Toys 'R Us or Radio Shack or Claire's. Remember those?
And Nasdaq-100 is fast-tracking SpaceX into its portfolio after 15 days. Soon, pension funds and 401(k)s are going to feature SpaceX stocks. So when it does implode, a lot of worker-class folk are going to eat the loss.
You know who I bet will not be eating the loss? Trillionaire Elon Musk.
My favorite part about data centers in space is it may actually be impossible from a physics standpoint to build the heat radiators large enough for even a small one. Even though space is cold and would seem to make sense, it is also a destructive vacuum and to radiate even a small amount of heat outside of a shielded core would take a huge array of radiators
No, it's totally possible. Not with any technology we've ever built, maybe not with any technology we can build, but physics doesn't preclude it outright.
Your point still stands though. It's a promise that's impossible to meet within the lifetime of the investors.
It’s possible, but not economical.
For basically any “space datacenter” scenario, imagine putting that same thing in a vast desert instead. You’ll find it’s easier and an order of magnitude cheaper.
Yeah, maybe not impossible, but I mean extremely unlikely. I found a thread on reddit that had examples and a spreadsheet https://www.reddit.com/r/IsaacArthur/comments/11kp7s4/how_large_of_a_heatradiator_would_a_spacecraft/
To run a data center in space you would need some kind of reactor producing around 100 MW. If rejecting 100 MW at 800 K
A= 100,000,000 / 0.85×5.670374419e−8×800
The number is the Stefan-Boltzmann constant (σ) https://physics.knox.edu/OnlineHW/zTest-PhysicalConstants.html
A≈5,065 m²
So roughly:
5,100 m² of radiating surface
That is a square about:
√(5065) ≈71 m per side
If it is a double-sided radiator panel, the physical panel area could be about half:
2,530 m² of panel, about 50 m × 50 m, assuming both sides radiate effectively.
Also temperature matters enormously so
At emissivity 0.85:
| Radiator temp | Area for 100 MW |
|---|---|
| 300 K | ~256,000 m² |
| 500 K | ~33,200 m² |
| 800 K | ~5,100 m² |
So the answer is about 5,000 m² (lol this is like "a football field" on each side) at 800 K, but balloons to absurd levels like hundreds of thousands of m² if you are trying to dump room-temperature waste heat which there would be a significant amount of. That is for a single small data center at current power needs. In the US alone data centers use 176 TWh (https://www.congress.gov/crs-product/R48646), so there is no chance we are going to be migrating a significant portion of it into space.
800K is 526C! You can't run a datacenter at that.
80C (still very hot for datacenter hardware coolant) is 350K. And there are other challenges, like effects from being in LEO, or proximity to wherever the solar array is.
And this is just one of MANY ridiclous engineering challenges. Another great example is that GPUs, memory, and SSDs get random bit flips in orbit, and the issue gets worse with smaller lithography: https://www.itpro.com/server-storage/high-performance-computing-hpc/367323/hpes-supercomputer-helps-iss-astronauts
There's tons of spam about "solving" this after the Tech Bro boom, but I don't really buy anything I've seen. Nothing but a bunch of lead (or the Earth's atmosphere) is going to stop fat gamma rays or extremely fast nuclei.
800K is 526C! You can’t run a datacenter at that.
Yeah, the temperature was an estimate for the nuclear reactor that would be needed lol, I tried to explain that most of the datacenter would be closer to room temperature which would require absurd sizes of radiators
To be fair, 100MW is pretty big.
AI doesn’t actually need that much. I’m pretty sure entire models like GLM 5.2 or Deepseek v4 are trained (and served) on a much, much smaller scale than a 100MW cluster.
But if that’s the case… why even invest in orbital data centers in the first place?
Why not desert ones? Why all this cash there instead of actually improving LLM architectures!?
There are so many nested levels of absurdity here. It’s all just total mania, with zero punishment to those doing the funding because they are too rich to feel any consequences.
Jesus Christ thank you for reminding me to confirm I keep his shit as far away from my pension as possible. Thankfully I'm in Canada so I feel there's a hope

Not mine. I'm selling my NASDAQ index fund next week. Thankfully the S&P said no.
This is probably the single most important thing we plebs can do.
