Meanwhile, Musk’s Grok project has faced scrutiny over content safety, yet he continues to promote Grok to his audience on X.

Long‑term implications point to deeper vertical integration among Musk ventures, possible monopolistic dynamics, and heightened regulatory attention across SpaceX, xAI and related tech.

The move is framed as a strategic cross‑promotion to boost xAI and Grok adoption by leveraging SpaceX’s market reach.

Grok, SpaceX’s AI chatbot acquired with xAI, has faced safety concerns but is central to the combined AI strategy and is valued within the broader SpaceX/xAI ecosystem.

Reaction is polarized: critics warn of coercion and regulatory risk, while supporters see cross‑industry innovation and potential AI tools benefits for finance.

Musk merged SpaceX with xAI in a deal shaping a unified AI strategy and estimated at roughly a trillion‑plus value for SpaceX and hundreds of billions for Grok.

Musk reportedly asked participating banks and advisers to advertise on X, with the advertising demand appearing less stringent than the Grok subscription requirement.

Leading banks and firms involved include Bank of America, Citigroup, Goldman Sachs, JPMorgan Chase, and Morgan Stanley, with Gibson Dunn and Davis Polk advising the deal.

The report notes an affiliate disclosure about commissions from linked purchases at the end of the piece.

Several banks have agreed to invest tens of millions annually in Grok subscriptions and are integrating the tool into their IT systems.

SpaceX is preparing a historic IPO expected to raise more than $50 billion with a valuation north of $1 trillion, while banks could collect over half a billion in fees.

Active bookrunners for the IPO include Morgan Stanley, Goldman Sachs, JPMorgan Chase, Bank of America, and Citigroup as preparations move forward.
