Wide-bandgap (WBG) power semiconductors – specifically Silicon Carbide (SiC) and Gallium Nitride (GaN) – are on a structural growth trajectory driven by superior power conversion efficiency (up to 30% improvement over silicon) and critical end-market demand from electric vehicles (EVs), AI data centers, renewable energy, and industrial electrification. The global power semiconductor market is forecast to expand from ~$58.8B in 2026 to $97.5B by 2035 (5.8% CAGR), with GaN growing faster at 9.03% CAGR to 2031 and reaching ~$3B by 2030 – a 400% increase from 2025. Heavy capex commitments, such as Infineon’s $2.4B SiC fab expansion, confirm industry conviction; however, geopolitical export controls, AI-driven capacity reallocation, and grid constraints present tangible risks.

| Ekspozycja na AI | High – generative AI is a major near-term catalyst, increasing demand for efficient power management in data centres; GaN and SiC are critical for reducing energy waste in 800V DC architectures. AI data centres alone may need an additional 92 GW by 2027, directly boosting WBG adoption. |
Secular tailwinds from electrification, AI infrastructure buildout, and energy efficiency mandates are durable, while GaN/SiC penetration remains low relative to silicon. Near-term catalysts (AI data center power demand, EV adoption, and new product launches) support an upward bias, though supply chain and regulatory risks temper extrapolation.
