🧬 What is HBM Memory?
HBM is a 3D-stacked memory that connects directly to the processor chip, offering massive bandwidth with low power consumption. It is essential for AI accelerators, supercomputers, and high-end GPUs.

📈 Why Is There a Shortage in 2026?
🚀 Explosive AI Demand
Every NVIDIA H100/H200, AMD MI300X, and Google TPU requires many GB of HBM. Data centers are ordering millions of chips.
🏭 Few Manufacturers
Only 3 companies produce HBM: SK Hynix (50%), Samsung (40%), Micron (10%).
⚙️ Complex Manufacturing
3D stacking requires specialized equipment and 18+ months for new factories.
🌏 Geopolitics
The US restricts exports to China, increasing pressure on the West.

🏭 The Three HBM Dominators
🥇 SK Hynix (Korea)
~50%
Market share
Leader in HBM3e, exclusive NVIDIA supplier
🥈 Samsung (Korea)
~40%
Market share
Supplies AMD, investing $15B in new factories
💰 Impact on Prices
| Product | Price 2024 | Price 2026 | Change |
|---|---|---|---|
| HBM3 (24GB stack) | $600 | $900 | +50% |
| HBM3e (36GB stack) | $1,100 | $1,500 | +36% |
| NVIDIA H200 (141GB) | $30,000 | $40,000+ | +33% |
The increases are passed on to AI GPUs, servers, and cloud services. Businesses using AI are seeing higher costs, while delivery times reach 12-18 months.
🌐 The Geopolitics of Chips
🎯 China: Locked Out
The US bans the sale of HBM3/HBM3e to China. Huawei is trying to develop domestic alternatives.
🇺🇸 USA: CHIPS Act
$52B in subsidies for domestic production. Micron is building an HBM factory in Idaho.

🇪🇺 Europe: EU Chips Act
€43B to reduce dependence on Asia. No HBM factory yet.
🔮 What's Coming: HBM4 and Beyond
Q4 2026
HBM4: 16-layer stacking, 48GB/stack, 2 TB/s bandwidth
2027
New SK Hynix and Samsung factories come online
2028+
Supply-demand equilibrium, price decline
📊 The Conclusion
The HBM war reflects the enormous importance of AI for the future. The countries and companies that control memory production will dominate the next industrial revolution. South Korea remains the leader, while the US and Europe are trying to reduce their dependence.
