TSMC is weighing Texas sites and a possible role in Elon Musk's Terafab project as it plans its next round of US expansion, Nikkei Asia reports.

The report names two directions for the world's largest contract chipmaker. First, additional fabrication capacity in Texas. Second, involvement in the Terafab concept promoted by Musk. Nikkei Asia gives no dollar figures, timelines or capacity targets in the reporting summarized here.

What does this change for chip buyers?

For now, nothing is decided. The story signals intent, not commitment. TSMC already operates US capacity in Arizona. Texas would extend that footprint. A Musk-linked Terafab would be a different kind of arrangement, tying TSMC to a single customer's scaling plans.

Buyers watching US supply should track two things:

• Whether TSMC confirms a Texas site and a capital budget for it.
• Whether any Terafab agreement defines volume, technology node or exclusivity.

Nikkei Asia's reporting is the current basis for the story. Die Signal will update as TSMC, Tesla or Texas officials confirm details.
