Palo Alto – October 11, 2026 –AI infrastructure has encountered a severe power wall caused by copper interconnect limitations, compelling the semiconductor industry to pivot rapidly toward silicon photonics and co-packaged optics (CPO). This technological transition brings optical engines directly next to compute silicon to drastically slash electrical trace length and energy usage.
Driven by this critical need, the market is experiencing explosive growth, with silicon photonics device-level revenue forecasted to surge from $3.1 billion in 2026 to $15.5 billion by 2031 at a 38% CAGR. Concurrently, the broader optical module market is expected to reach $201.0 billion, with CPO rapidly expanding from 2% to capture 56% of total module revenue by 2031.
Major industry players are aggressively securing vital control points across the supply chain through high-stakes acquisitions and strategic investments, such as Marvell’s $3.54 billion acquisition of Celestial AI and multi-billion-dollar stakes by NVIDIA. Woodside Capital Partners emphasizes that this strategic acquisition window is currently open, prompting companies to consolidate critical layers like packaging, testing, and manufacturing capacity before the market fully matures.
