DeepSeek Wants Its Own Chip Too: Inference-First, Nvidia and Huawei Shown the Door

China's most formidable AI lab has decided it's done buying GPUs on other people's terms.

Three key facts

Per a Reuters exclusive on July 7, DeepSeek is designing an in-house AI chip built specifically for inference — the stage after a model is trained, when it actually answers users' questions. Three sources say DeepSeek has spent roughly a year in talks with chip-design, foundry, and memory partners while quietly hiring chip engineers, all to reduce its dependence on Nvidia and Huawei silicon. The project is still early: no named partner, no prototype.

On the news, Nvidia shares slipped about 2% pre-market. A startup that hasn't fabricated a single chip made the world's most valuable chipmaker flinch just by being rumored to want its own silicon — which tells you how nervous the market is about the moat around Nvidia's inference business. DeepSeek made its name on cheap models; if it owns the chip too, costs can fall further still.

But there's a wall in DeepSeek's way: manufacturing. US export controls bar Chinese firms from TSMC's most advanced lines, pushing them toward domestic foundry SMIC, whose leading-edge capacity is tight and yields shaky. Whether it can reliably mass-produce an inference chip is a real question. Designing a chip is one thing; building it — cheaply — is another.

WangDou's Take

Silicon Valley has run this script several times: OpenAI with Broadcom, Anthropic with Samsung, Google's TPUs, Amazon's Trainium — big buyers tired of Nvidia's margins are grinding their own knives. DeepSeek is just staging the same play in a China that's been cut off. The difference: everyone else builds custom silicon to save money; DeepSeek does it half to save money and half because it can't buy what it wants. The real suspense isn't in the design — it's on SMIC's production line. The prettiest blueprint is worthless if the fab can't press a clean wafer. And Huang shouldn't lose sleep over that 2% dip: a project still at the "chatting with suppliers, quietly recruiting" stage is a very long way from tape-out. That sell-off wasn't about DeepSeek's chip — it was the market flinching at its own faith in Nvidia's valuation.
