Samsung and SK Hynix were nursing over 20% losses in March amid growing concerns over long-term memory chip demand from the artificial intelligence industry, especially after Google unveiled a new algorithm which it claimed could slash AI’s memory requirements.
More recently, markets also began speculating over a potential fall in memory chip prices due to spending cuts at AI major OpenAI. The company recently shuttered its video generation model Sora.
OpenAI had in late-2025 signed an agreement with Samsung Electronics and SK Hynix to source 900,000 DRAM wafers from the two– representing a major chunk of supply.
