ARTHOS Semiconductor M&A Report:
AI-Boom Fuels Dealmaking and Stock Market Valuations

Personal Note: AI-boom fuels semi dealmaking and stock market valuations in the semiconductor industry

Typically, stock markets rise first, enabling publicly listed companies to pursue larger, higher-priced transactions. This time, however, total deal value accelerated in early 2025, with stock markets following in the second half of the year. I
would like to highlight three key observations:

  1. Extraordinary increase in M&A deal value – driven by large-scale transactions
  2. Demand for AI drives semiconductor shares to new highs
  3. Sony Semiconductor and TSMC signed an MoU to form a Joint Venture for next-generation image sensors.

1.) Extraordinary increase in deal value, driven by large-scale transactions

Cumulated semiconductor deal value increased extraordinarily from ~EUR 8bn in 2024 to ~EUR 75bn in 2025 and is expected to rise further in 2026, driven by large deals.

Typically, deal value and deal count rise in tandem; however, CIQ data indicate only a modest increase in deal count, although actual activity is likely higher as many smaller strategic transactions remain undisclosed.

The clear highlight is NVIDIA’s ~USD 20bn acquisition of Groq’s chip assets, enabling NVIDIA to internalize cutting-edge, ultra-low-latency ASIC technology and further strengthen its leading market position. The next big M&A rumor: Intel‘s or Qualcomm‘s USD 8- 10 bn acquisition of Tenstorrent.

2.) Demand for AI drives semiconductor shares to new highs

Stock prices are booming across the whole semiconductor industry. Since July 2025, the Philadelphia Semiconductor Index has risen by 141%. The growing number of public market offerings indicates that many participants view semiconductor valuations as elevated. What began as a race for AI chips is now being fueled by an accelerating AI infrastructure boom and has broadened across multiple semiconductor segments, including Power Semiconductors, which are expected to grow at a ~25% CAGR. Market players are also positioning themselves in this segment through M&A, as seen by Skyworks’ acquisition of Qorvo and the Japanese merger of the powerdevice businesses of ROHM, Toshiba, & Mitsubishi Electric.

3.) Sony Semiconductor and TSMC signed an MoU to form a Joint Venture for next-generation image sensors.

This is remarkable, as the global leaders in image sensors, Sony, and high-end logic manufacturing, TSMC, are jointly well positioned to dominate the imaging sensor market for years to come. For Sony, this marks a first major step towards a
fab-light business model, while the JV will target not only its current core smartphone market but also emerging physical AI applications, advanced automotive, and robotics.
