Orbital data centers may take far longer than investors expect, if they happen at all. SpaceX sells compute on Earth and invests in power and cooling there, widening the hype-reality gap. SpaceX, Rocket Lab, AST SpaceMobile and Redwire could be dead money for years while the vision catches up. x.com 

SpaceX's $2T valuation may price in orbital data centers that remain a distant vision. Its operating business is essentially a scaled neocloud and internet provider, raising the question of whether current operations justify that valuation. x.com 

SpaceX can capture more upside from AI compute scarcity by selling capacity near spot prices instead of locking in today's rates. Potential Anthropic and Google commitments total about $151B, with 90-day termination rights, while bare-metal pricing has risen from $10-15M to nearly $50M in annual revenue per MW. Elon Musk says contract payback could be as short as six months in 2027. x.com  x.com 

SpaceX's 10 GW compute target demands enormous capital spending. It alone would have to reach $500B in capex to meet the goal. x.com 

SpaceX's AI-cloud ambitions face a severe two-sided constraint: finding 12 GW of Rubin capacity in one year looks implausible, and even that buildout would need customers willing to rent roughly $50B of compute annually. The scale of both the supply and demand challenges makes the plan highly skeptical. x.com 

SpaceX's compute outlook improves as Anthropic commits more spending and institutions fund its GPU expansion. Anthropic's S-1 lists up to $120.5B in SpaceXAI compute purchases through 2029; Pimco bought $4B of the roughly $40B Apollo-led GPU debt package. The GPU lease is expected to close before year-end and entails about $40B in principal payments, not new shares. Elon Musk says Starlink Mobile will take 2-3 years to build out, versus the 4-6 years estimated by Verizon's CEO. x.com  x.com  x.com  … Show more

SpaceX's neocloud-driven valuation is vulnerable to short-notice compute contract exits. Losing contracts with 90-day out clauses could cut $500B from its valuation; at least one out clause appears to be coming in 2027 rather than 2029. Neocloud expectations drive 80% of its current valuation, despite earlier fundraising on Starlink, reusable rockets and Mars. What happened to Amazon in 2000-02 is about to happen to SpaceX by 2030-32. x.com  x.com 

SpaceX's projected 2027 revenue relies on effectively unlimited demand for data-center rentals at $50 per watt per year, though a data center costs less than $50 per watt to build. Elon Musk assumes 10-20 GW at that rental rate would bring in $500 billion-$1 trillion. Setting that expectation for shareholders is irresponsible at best and hard to distinguish from a scam at worst. x.com 

SpaceX's compute buildout looks undercounted because Deutsche Bank models signed IT-load leases, excluding Grok's internal use and facility overhead. DB's 4.5GW upside case is about 6.5GW on Musk's nameplate basis, versus his 13GW end-2027 guidance; SpaceX could reach close to 6GW by end-Q1. DB's $216B 2027 compute exit ARR upside is below the $238B bear case, with near $500B expected, perhaps more. Per DB, vertical integration puts build cost near $35-36B/GW versus about $50B for peers. x.com  … Show more

SpaceX's revenue ambitions look implausible against current sales and the risk of overbuilding chips. Revenue is $14 billion this quarter, and even the Street's $120 billion forecast for next year looks aggressive. Its costs are within its control, leaving the risk heavily skewed against investors. x.com
