The Wide-Bandgap Power Semiconductor Market Is Projected to Experience Robust Growth at a 21.4% CAGR Through 2030 - einnews.com

The 21.4% CAGR headline masks a deadlier signal: capacity misalignment. The 2022 SiC substrate crash—from $1,500 to $800 per wafer—proved that linear capital chasing exponential demand guarantees a 2-3 year price war. Growth drivers have shifted from EV monoculture to a triad: AI data centers, EVs, solar. GaN-on-Si penetration in 48V server power will breach 30% within 18 months, restructuring MOCVD orders at Veeco and AMEC while forcing foundry partners in Taiwan, China to accelerate GaN ramp-up. Compliance-wise, gallium-germanium export restrictions have structurally raised GaN epitaxy costs, while US controls on 8-inch SiC equipment have frozen Wolfspeed's expansion. This is structural decoupling, not friction—European OEMs now absorb dual-supply-chain premiums. Infineon and onsemi will likely close SiC module vertical integration by Q3 2025. Sanan and SICC will compress substrate costs another 15-20%. If Wolfspeed's yield problem persists, expect 8+ percentage points of share loss within 24 months. By 2026, 8-inch SiC replaces 6-inch, triggering a brutal purge—30% of mid-tier substrate players exit. The winner won't be the best engineer; it will be the one with the thickest balance sheet.
