ByteDance, the company behind TikTok, is building its own CPUs. The reason is straightforward: buying them from Intel and AMD has become painfully expensive.
CPU prices from major suppliers have climbed 10-35% quarter-over-quarter, according to Reuters, and supply constraints have stretched expansion timelines to the breaking point. For a company projected to spend RMB 160 billion (roughly $22.8 billion) on AI-related capital expenditures in 2026, those price hikes add up fast.
The custom silicon play
ByteDance is currently in early-stage development, evaluating both Arm and RISC-V architectures for the new chips. The company is also seeking partnerships for design and manufacturing, which suggests it’s not trying to build a full-stack semiconductor operation from scratch.
The target use case is internal. These CPUs are meant to power ByteDance’s own servers and data centers, with a particular focus on supporting agent-based AI products like its Coze platform.
