Qualcomm, Marvell Fall on ByteDance Custom Chip Deal

Shares of Qualcomm (NASDAQ:QCOM) fell 8% to $201 in Tuesday morning trading, while Marvell Technology (NASDAQ:MRVL) dropped 10% to $260. The catalyst is news that ByteDance, the parent company of TikTok, is advancing a custom AI silicon (ASIC) deal that directly touches Qualcomm, reshaping the merchant custom-silicon narrative across the sector.

Potential Causes

Reports indicate ByteDance is developing custom ASICs (application-specific integrated circuits) with new suppliers, reducing its reliance on Qualcomm's existing chips. This development threatens Qualcomm's market share in custom AI chips, especially as demand for tailored solutions grows among tech giants. Marvell, also active in custom silicon, was caught in the selling pressure that swept the sector.

Context

Custom semiconductor stocks have experienced sharp volatility in recent weeks amid concerns over slowing demand and increased competition. The decline follows strong performance earlier this year for both Qualcomm and Marvell, which benefited from the AI boom. However, the ByteDance deal signals a potential shift in market dynamics as major companies develop their own chips to cut costs and improve efficiency.

Similar Moves in the Sector

Losses were not limited to Qualcomm and Marvell; other custom chip companies like Broadcom (AVGO) and Synopsys (SNPS) also declined by varying degrees. This trend reflects investor concern that custom chip deals could erode market share for traditional suppliers.
