SpaceX Overtakes TSMC in Market Cap; Semiconductor Sector Watches (NVDA)
What happened
SpaceX has surpassed Taiwan Semiconductor Manufacturing Co. to claim the sixth-largest market capitalization globally, according to reporting from The Motley Fool dated June 18, 2026. The private space and technology company's valuation milestone reshuffles the ranking of the world's most valuable firms. TSMC, a critical supplier to NVDA and the broader semiconductor supply chain, now ranks outside the top six. The source piece also weighs whether SpaceX's valuation remains attractive at current levels.
The QL Read
NVDA carries a composite signal score of 81/100 and gained 2.78% on the session against a broadly constructive tape, with 58.5% of issues advancing. A TSMC valuation reset in the pecking order is worth monitoring for any read-through to foundry pricing power and NVDA's chip production costs.
