About AXT
AXT manufactures compound semiconductor substrates, the specialty wafers on which optical and radio frequency chips are built. Its customers make the lasers, detectors, and transceivers used in data centers, telecom networks, and sensors, and AXT supplies the base material those devices start from.
Indium phosphide substrates are the growth engine: they underpin the high speed optical transceivers and silicon photonics that link AI data center clusters, and demand has surged as AI networks scale. Gallium arsenide and germanium substrates serve wireless, LED, and satellite markets, while partly owned raw material companies in its supply chain provide key inputs.
Founded in 1986 and headquartered in Fremont, CA, AXT employs about 1,500 people, lists on NASDAQ under AXTI, and is expanding its indium phosphide capacity.
AXT in the AI buildout
AXT spans the Raw Materials and Networking layers of the buildout, with a foothold in the Chip Equipment layer through its substrate supply chain. AI clusters are connected by optical links, those links are built on indium phosphide lasers and photodetectors, and AXT is one of the few merchant suppliers of the InP substrates beneath them. As clusters scale, optics demand compounds and pulls substrate demand with it. Legacy gallium arsenide and germanium products tie the rest of the business to broader electronics markets.
AXTI is tracked in Raw Materials & Mining, Chip Equipment & Foundries and Networking & Optics, rated Strategic on the AI Exposure leaderboard.
