Macrohard and Terafab: The Tesla and SpaceX Joint Ventures Wall Street Hasn't Priced In

SpaceX’s S-1 reveals two early-stage joint projects with Tesla — Macrohard (an agentic AI platform) and Terafab (a vertically integrated chip fab) — that Wall Street has largely not priced in. The article argues the AI infrastructure buildout benefits several companies differently: NVIDIA is the near-term cash winner, Applied Materials is the broad, durable beneficiary regardless of which foundry wins, and Tesla is a high-upside wildcard if Terafab/Macrohard advance. Market signals are mixed: AMAT is up strongly YTD, NVIDIA shows exceptional revenue momentum, while Tesla has lagged but retains asymmetric optionality. Investors should watch Tesla’s next earnings call and SpaceX disclosures for project detail; in the near term, exposure through equipment (AMAT) or GPUs (NVDA) looks more certain than direct Tesla upside.
