Shares of GlobalFoundries were on the rise after the semiconductor manufacturer said it teamed up with Corning in a deal aimed at giving the company a competitive edge in the global chipmaking race.
GlobalFoundries' stock rose to $37.45, up more than 5% in midday trading. Monday's uptick continues the stock's multiday rise after the Wall Street Journal reported the Trump administration is weighing a plan to have chip companies manufacture the same number of semiconductors in the U.S. as their customers import from overseas producers, potentially giving GlobalFoundries and its peers more leverage in discussions with customers.
GlobalFoundries on Monday said it would collaborate with Corning, which makes specialty glass for smart phones and TVs, to create detachable fiber connectors for GlobalFoundries' silicon photonics platform. The partnership will use Corning's GlassBridge technology to address a common bottleneck for AI datacenters: insufficient optical interconnects can lose signal, generate heat and limit bandwidth, especially in high-demand environments such as datacenters.
"Corning's cutting-edge fiber technology, integrated with our silicon-proven platform, delivers the performance and flexibility required for enabling scalable, high-density optical packaging for AI datacenters," GlobalFoundries Senior Vice President Kevin Soukup said.
The companies are developing other technologies through the partnership, such as a vertically coupled detachable fiber-to-photonic-integrated-circuit solution.
The companies didn't disclose the value of their collaboration.
GlobalFoundries previously disclosed it is working with the Trump administration on a $16 billion investment to reshore its chip manufacturing and expand its operations in New York and Vermont.
