Qualcomm and Marvell Shares Slump as Tech Giants Pivot to Custom Silicon

Key Facts

As tech giants increasingly pivot toward technological self-sufficiency, the semiconductor sector faced notable selling pressure affecting traditional hardware suppliers. Qualcomm shares dropped 8% to $201 following reports regarding a ByteDance custom ASIC deal. Similarly, Marvell Technology shares fell 10% to $260, as investors worry that the trend of major tech firms designing their own silicon will reduce reliance on off-the-shelf products from established chipmakers.

This shift mirrors broader strategies seen at firms like Apple and Amazon, which have successfully developed in-house processors to lower costs and optimize performance, placing competitive pressure on traditional chip margins. In comparison to peers, Nvidia has maintained relative stability due to its AI dominance, while Qualcomm and Marvell remain more exposed to custom-silicon shifts per market data. These declines come as investors evaluate the ability of these manufacturers to diversify their client base away from firms moving toward internal production.

Regarding current price levels, QCOM stood at $202.96 while MRVL closed at $280.71 (close June 11, 2026). Traders are monitoring macroeconomic data for impacts on tech sector risk appetite, especially following the US Unemployment Rate holding at 4.3% as of June 5. With few direct catalysts in the upcoming economic calendar, focus remains on any official statements from ByteDance or supply contract updates to determine the sector's next direction.
