For AI and ML practitioners, investor narratives that convert compute and data ambitions into massive addressable markets reshape funding and product roadmaps across the stack. DimsumDaily reports Jeremy Grantham said he would "bet at least 90%" on a sharp reversal in SpaceX's share price and described parts of the company pitch "utterly inconceivable" (DimsumDaily, July 8). Reporting by The Next Web notes Raymond James analyst Brian Gesuale opened coverage with an **$800** price target implying about a **$10.5 trillion** valuation. DimsumDaily and The Next Web report SpaceX began trading around **$150** after its IPO and joined the **Nasdaq-100**; DimsumDaily also cites the company estimating a **$28.5 trillion** total addressable market with roughly **90%** attributed to AI. These claims have prompted renewed scrutiny of AI-driven valuation narratives.
