TSMC raises its prices on mature nodes starting January 2027

The cheap silicon floor is rising: AI demand on advanced nodes spills over to older processes.

In plain terms

TSMC has warned "several" customers of a price increase on its mature nodes - the older processes that manufacture most non-AI silicon (power management, sensors, microcontrollers, automotive chips) - starting January 2027. The foundry did not communicate the extent of the increase; it "will vary according to the customer".

Our analysis (follow-up - tsmc-compute-crunch)

The notable fact is not the amount, it's the direction. TSMC cites three drivers: AI demand, product mix optimization, and upstream material cost increases. Translation: the rush for advanced nodes - where GPUs are manufactured - is so strong that TSMC is reallocating its capacity and leaving mature processes to tighten. After a June revenue boosted by the advance, this is the second side of the same squeeze. When the leader moves, the rest follows: second-tier foundries have already raised their prices. The cost of AI is therefore not limited to high-end GPUs; it goes up the chain and increases the price of "ordinary" silicon that the automotive, home appliance, and industrial sectors depend on. This is the displacement effect of the AI boom in its most discreet form.

To watch

The quantified extent when it leaks, the reaction of automotive customers (big consumers of mature nodes), and whether UMC or GlobalFoundries follow suit openly.
