Multiple signals point to headwinds for TSMC's AI chip dominance.

Multiple signals point to headwinds for TSMC's AI chip dominance. First, a Nikkei Asia report (June 23) reveals that Google, Tesla, and AMD are turning to Samsung for AI chips, citing Samsung's advanced foundry capabilities and competitive pricing. This represents a potential design loss for TSMC, as these major customers diversify away from its leading-edge nodes.

The mandate, part of a $295 billion domestic chip push, will reduce orders for TSMC from Nvidia and other US suppliers.
