Why a few words from Elon Musk can (and did!) move a $600 billion+ chipmaker
Elon Musk confirmed TSMC is in talks to join Terafab, a Texas chip venture backed by Tesla, SpaceX, and xAI. Intel shares fell over 2% after the news, while TSMC's shares rose. TSMC's involvement could shift Intel's role from sole manufacturer to a shared one, impacting Intel's foundry ambitions. Intel's valuation is heavily tied to future foundry wins, making the news significant for investors.
