GlobalFoundries is a semiconductor foundry that manufactures chips for a broad range of customers, focusing on feature-rich, reliable technologies for cars, IoT, 5G, and other high-growth markets. It operates by fabricating silicon wafers for customer designs, offering mature, specialized processes rather than chasing the most advanced nodes. This makes it different from peers that prize the latest process nodes; GlobalFoundries emphasizes diversification across a global manufacturing footprint (U.S., Europe, Singapore) and stable supply for essential applications. Its goal is to be a leading supplier of high-volume, specialty manufacturing that enables reliable chips for everyday devices and growing tech markets.

GlobalFoundries sees silicon photonics hitting $1B+ run rate by 2028 as AI data centers drive optical interconnect demand

GlobalFoundries is positioning silicon photonics as essential infrastructure for AI data centres, arguing that copper-based connectivity becomes fundamentally limited beyond 200 gigabits per lane. The company says optical interconnects scale more effectively for reach, bandwidth density and energy efficiency as AI systems drive growth in "east-west" machine-to-machine traffic. The chipmaker is deploying a full silicon photonics stack across 200mm and 300mm fabrication facilities in New York and Singapore, with a co-packaged optics facility planned for Malta, New York in 2025. Recent acquisitions of AMF and InfiniLink have expanded its capabilities. Management expects silicon photonics revenue to double in 2026, with a clear path to exceeding $1 billion annual run rate by end-2028. The company estimates its serviceable addressable market will reach approximately $11 billion by 2030.
