What it does

GlobalFoundries (GF) is a U.S.-headquartered contract chipmaker that manufactures specialty and mature-node chips for other companies in fabs across the U.S., Europe and Singapore, with strengths in radio-frequency, silicon germanium, power and silicon photonics technologies.

Why it matters

GF does not make leading-edge AI processors, but its silicon photonics and silicon germanium processes are used for the optical links inside AI data centers, and it has launched a quantum chip foundry service; its CEO cited optical networking in the AI data center as a growth driver in August 2026.

How it makes money

Chip design companies pay GF to manufacture wafers of their chips, often under multi-year supply agreements.

Geography

United States (Malta, New York)

AI stack position

Chip manufacturing, memory and packaging. The foundries, memory makers, and packaging and testing businesses that physically manufacture AI chips. This is where a chip design actually becomes a real, physical piece of silicon.
