Intel’s stock drops after Musk hints at an additional partner for big chip venture

Intel shares moved lower after Elon Musk indicated that the company may not be the sole semiconductor partner for the Terafab chip manufacturing venture. Musk said discussions with TSMC are also ongoing, suggesting Intel could share fabrication responsibilities—or face competition for them—rather than serving as the exclusive provider.

The reaction reflects how sensitive Intel's turnaround narrative has become to any signal about large-scale manufacturing contracts. A venture of this profile would represent meaningful demand for advanced fabrication capacity, and investors have treated such potential deals as validation of Intel's foundry ambitions. The prospect of a rival foundry entering the picture introduces uncertainty about how much of that work Intel ultimately captures.

What to watch: whether Intel and TSMC confirm formal roles, and how the scope of any agreements is defined. Details on volumes, timelines, and process nodes would clarify the venture's real significance for Intel's foundry business. For now, the headlines illustrate how quickly sentiment can shift when a potential deal's structure is still unsettled.
