Musk says Tesla's mega AI chip fab project to launch in seven days

Japanese vendors are unlikely to fully back Elon Musk’s Terafab project, and the reason is simple: Panasonic. After overextending resources for the Gigafactory and accepting razor-thin margins, they felt "discarded" once Tesla pivoted to in-house battery tech. For Japanese firms, being treated as a disposable tool rather than a strategic partner is the ultimate Japanese business taboo. Without a foundation of mutual trust, the Japanese ecosystem will fully support Musk.

Especially in today’s environment of acute capacity shortages, the choice for suppliers is clear. If you are a Japanese vendor with limited output, would you prioritize a long-term, high-trust partner like TSMC, or a brand-new, volatile venture from Tesla

FWIW, Panasonic is still a large chunk of Tesla's battery business, even today, and are probably selling Tesla more cells than when the JV formed.

Panasonic has also failed to keep up with the Chinese battery makers in terms of tech -- they have no LFP offerings for example (big mistake), nor do they seem to be keeping up with CATL in terms of charging performance for NCM / NCA batteries. Tesla had to go to Panasonic's competition for LFP, and in-house to try to advance tech beyond what Panasonic offers today (4680 dry process, and "battery as structure").
