Robert Shiller on SpaceX
SpaceX’s proposed AI-unit rename gives its valuation story a new label, but the reported name followed the latest price move and leaves the spending test unchanged.
Shiller’s feedback-loop test asks whether a rising price prompts a new-era explanation that recruits more buyers. Per DeadRisk’s market layer, SpaceX closed on October 2 up 7.35%, to $158.96 from $148.07 at the previous close. SpaceX remained below its $160.95 June debut close. Reuters later reported Musk’s X reply that he would rename SpaceXAI to SpaceXSI, adopting the language of “super intelligence.” SpaceX’s close preceded that report. The record cannot assign the price move to the proposed name, and Reuters did not report a completed rename or an earnings change.
The record also corrects a comparison in this lens’s July take. The Information’s $250 billion figure valued the xAI acquisition; Bloomberg’s $1.25 trillion figure valued the combined company. The two February deal reports did not price the same asset, so the record cannot treat their ratio as a fivefold repricing. Shiller’s new-era test does not need that mistaken comparison: it asks whether a change in description outruns a demonstrated change in earning power.
SpaceX’s first public quarterly report supplies an operating check. Per the Q2 earnings coverage, SpaceX reported $7.8 billion of revenue in Q2 2026, versus $4.7 billion in Q1 2026. SpaceX spent $18.4 billion on capital projects in Q2 2026, versus $2.8 billion a year earlier; its $15.8 billion of AI capex that quarter exceeded its $2.56 billion of AI revenue. The Information’s Microsoft report describes talks about leasing compute capacity, not a signed sale. Bloomberg’s subscription report describes planned Grok and X tiers, not paid uptake. Culpium’s TSMC account reports confirmed discussions without terms, not a chip-supply contract.
Per the TEXXR coverage record, SpaceX appeared in 72 tagged articles in Q3 2026, versus 158 in Q2 2026; each count covers one calendar quarter’s archive articles, not launches or customers. The record shows less coverage after the listing quarter. It does not show whether buyers accepted the latest new-era description. That missing link keeps Shiller’s price-to-story-to-buyer mechanism a test here, not a proven cause.
