When you're winning the race, the smart move is to run faster. That's exactly what SK Hynix is doing as it throws another $13 billion at the AI memory boom, hoping to lock in its lead before rivals like Samsung Electronics (SSNLF), Taiwan Semiconductor Manufacturing Company (TSM), and Micron Technology (MU) catch up.
A $13 Billion Bet on AI's Future
SK Hynix, the world's leading supplier of high-bandwidth memory to Nvidia (NVDA), just announced plans to build a massive new semiconductor packaging and testing facility in South Korea's Cheongju Techno Polis. The price tag? About 19 trillion won, or roughly $13 billion.
The new plant, dubbed P&T7, will break ground in April. Construction should wrap up by 2027, with full operations kicking off in 2028, according to the Korea Economic Daily. The facility will focus on advanced packaging, which is essentially the process of stacking and combining multiple memory chips into dense, high-performance units that AI systems desperately need.
This isn't just about making more chips. It's about making them work better together. Advanced packaging improves both performance and energy efficiency, two things that matter enormously when you're training massive AI models or running generative AI workloads that chew through data at staggering rates.
The Competition Is Heating Up Fast
SK Hynix isn't operating in a vacuum. The high-bandwidth memory market has become a battleground, and everyone wants a piece.
Samsung has announced aggressive plans to ramp up HBM production, and it's already flexing its pricing power. The Korean giant has hiked prices on key memory chips by as much as 60% since September, capitalizing on surging demand and tight supply.
Meanwhile, Taiwan-based rivals like TSMC and U.S. players like Micron are scrambling to secure their own capacity. The stakes are high because HBM has become absolutely critical for AI infrastructure. These chips are what make it possible to train large language models and power the AI accelerators used by Nvidia, Alphabet's Google (GOOGL), and Advanced Micro Devices (AMD).
Right now, SK Hynix dominates the field with a 53% share of the global HBM market in the third quarter of 2025. Samsung follows with 35%, and Micron holds 11%, according to Counterpoint Research. But those numbers could shift fast as competitors pour billions into new capacity.
SK Hynix itself expects the global HBM market to grow at a 33% compound annual rate from 2025 to 2030. That kind of growth doesn't happen often, and it explains why everyone is racing to build out production.
