Anthropic’s Custom AI Chips Could Be Built on Samsung’s 2nm Process - SammyGuru

Anthropic's bet on Samsung's 2nm node is a structural fracture in the AI compute supply chain, not a routine sourcing decision. Technically, a successful custom ASIC tape-out directly attacks NVIDIA's 75%+ gross-margin moat. If Samsung's GAA architecture clears 85% yield, its vertical integration—pairing HBM3E with 2nm SoC—creates a credible alternative to TSMC's CoWoS ecosystem, forcing upstream EDA and photoresist suppliers to reprice. On compliance, the US-Korea semiconductor alliance framework largely neutralizes export-control exposure, but any packaging outsourcing to Taiwan, China still sits in BIS's gray zone. Competitively, TSMC will likely respond with N2+ acceleration and price concessions; AMD will tighten its OpenAI partnership; Intel Foundry may seize the 'third option' narrative via 18A. Over the next 12–24 months, in-house AI silicon shifts from optional to mandatory, and the custom ASIC market will likely exceed $40B by 2026. Samsung's existential line: Q4 2025 yield data. Below 80%, the entire thesis collapses overnight.
