It's circular since Google owns part of SpaceX. According to [1] they own 7% of SpaceX, so a $1.75T IPO would value their stake at $120B. The target IPO price is >90x revenue, so if Google increases SpaceX's revenue by $11B, SpaceX's valuation could increase by $990B to maintain the same multiple, which would increase the value of Google's stake by $69B.

Their exposure is more than just their ownership of SpaceX.
If the SpaceX IPO bombs (or even merely underperforms), the expectations for the Anthropic/OpenAI IPOs collapse, and with that, everything else AI.
AI companies can't afford to let any AI company go down.

Not what circular financing means. Buying from a company you own stock in can be a conflict of interest, but it's only circular if you invest in the company and then they use those proceeds to buy your stuff. A past investor buying services from a company they are affiliated with is pretty par for the course in business.
