Nokia expands semiconductor operations in Pennsylvania to boost AI growth

Nokia is betting big on American silicon. The company announced a major expansion of its advanced test and packaging operations in Allentown, Pennsylvania, targeting a tenfold increase in photonic chip and optical module production capacity to feed the insatiable demand of AI infrastructure.

The new production capabilities are expected to come online by the end of Q3 2026.

What Nokia is actually building

Nokia’s Allentown facility focuses on advanced test and packaging, or ATP, for photonic chips and optical modules. The expansion is part of Nokia’s broader $4 billion commitment to US research, development, and manufacturing, first announced in November 2025. Roughly $500 million of that total is earmarked for manufacturing and R&D operations spanning multiple states, including Texas, New Jersey, and Pennsylvania.

Nokia expects the Pennsylvania site alone to employ over 500 workers once the expansion is complete. The company projects an economic impact exceeding $500 million over the next five years from this single facility.

Nokia claims its optical technologies can reduce energy consumption in AI communications by as much as 75%.

The Infinera acquisition set this up

Nokia completed its $2.3 billion acquisition of Infinera in February 2025, a deal that brought US-based semiconductor manufacturing assets into Nokia’s portfolio. The Allentown facility and its capabilities trace directly back to that acquisition, which was partially supported by investments tied to the CHIPS Act.

US domestic semiconductor advanced test and packaging capacity currently accounts for less than 2% of the global total.

CEO Justin Hotard framed the expansion as a direct investment in scaling domestic manufacturing of optical networking technologies that underpin AI infrastructure.

What this means for investors

The tenfold capacity increase is the number to watch. If Nokia can deliver on that scale-up by end of Q3 2026, it positions the company as one of the few Western manufacturers with significant ATP capacity for optical components, in a market where nearly all advanced packaging currently happens in Asia.

The energy efficiency angle deserves attention. Data center power consumption is becoming a genuine constraint on AI scaling. Nokia’s optical tech claims a 75% energy reduction in AI communications, which would make it a necessity for operators hitting power ceilings.
