The valuation of SpaceX is viewed as increasingly attractive at approximately double that of Anthropic, driven by diversified revenue from Starlink cash flows and launch services. The company is expanding its "sum of the parts" value through a partnership between SpaceXAI and Cursor to train the Grok 4.5 AI model. Benchmarking data shows Grok 4.5 competing closely with models like Opus 4.8 and GPT-5.5 across technical performance metrics.
