Silicon carbide, a power chip material that handles high voltages more efficiently than silicon, is at the center of a Chinese capacity build out aimed at absorbing the surge in electricity demand from next generation AI facilities.
Basic Semiconductor's planned IPO marks the first public test of whether silicon carbide, a power-electronics material that handles high voltages more efficiently than silicon, can become the next infrastructure bet for AI data centers (South China Morning Post). The Chinese chipmaker, founded in 2016 by graduates of Tsinghua University and the University of Cambridge, is positioning itself for an expected surge in demand from new power-hungry AI facilities that will need to switch to higher-voltage electrical architectures to operate efficiently.
The company is not alone in its wager. Peers Silan Microelectronics and China Resources Microelectronics are also expanding silicon carbide production, part of a coordinated Chinese push that has turned the once-niche material into a flashpoint for global supply-chain anxiety. Silicon carbide, or SiC, is a compound semiconductor used in power-conversion chips rather than the logic or memory chips that dominate headlines; it loses less energy as heat at high voltages, which makes it attractive for electric vehicles, industrial equipment, and the power-supply systems inside large data centers.
That positioning bet looks aggressive against the current market backdrop. UBS analysts have warned that the global silicon carbide market is oversupplied today, the result of an aggressive Chinese capacity expansion that has outrun near-term demand. The bank's view, echoed by independent industry researcher Yole Group in December, is that the oversupply is real and visible in pricing and inventory data, and that it will persist until data-center operators begin the long-anticipated shift to 800-volt direct-current power architectures projected for 2027–2028 (Yole Group, via Semiconductor Today).
The 800-volt transition is not hypothetical. Nvidia's Kyber reference architecture, announced for 2027 deployment, calls for 1-megawatt server racks powered by 800-volt DC distribution, a step change designed to cut conversion losses and fit more compute into a single rack (Data Center Dynamics). If the transition lands on schedule, it will pull silicon-carbide-based power conversion from today's small share of data-center silicon into the mainstream, and the Chinese cohort's bet will look prescient rather than overbuilt.
For now, the calculus is a timed wager on that transition landing on time. Basic Semiconductor's IPO prospectus, when filed, will offer the first hard look at a Chinese silicon-carbide company's order book, customer mix, and 8-inch wafer migration plans, signals that will tell investors whether the cohort is positioning for genuine demand or building inventory into a glut. The thesis breaks cleanly: if 800-volt adoption slips past 2028, or if AI data-center growth slows enough to delay the power-architecture overhaul, the Chinese silicon-carbide capacity now coming online will sit unsold and the bear case will dominate.
What to watch next: Basic Semiconductor's IPO timing and any disclosure of 8-inch wafer capacity milestones from Silan Microelectronics and China Resources Microelectronics through 2026, which will reveal whether the oversupply is widening or narrowing before the 800-volt demand pull arrives.
