Overview

Asian semiconductor equities experienced a sharp decline on Thursday, echoing a steep overnight sell‑off in U.S. chipmakers. The tumble was triggered by two concurrent reports: OpenAI’s engineers achieved software optimisations that cut inference costs by roughly half, and Meta Platforms announced plans to monetise surplus AI computing capacity through a new cloud offering.

OpenAI Efficiency Gains

According to a report from The Information, the OpenAI team developed optimisations that reduce the number of Nvidia graphics processors required to serve certain ChatGPT users by about 50%. This reduction in hardware demand raised market concerns that the growth trajectory for AI‑specific chips could be slower than previously projected.

Meta’s Cloud Initiative

Bloomberg News reported that Meta Platforms is exploring a cloud‑based service that would allow customers to access AI models and spare computing power. The initiative aims to generate returns from Meta’s extensive AI infrastructure investments and could further temper the urgency for new chip purchases.

Impact on Asian Chipmakers

The combined effect of the OpenAI and Meta developments led to pronounced price drops across major Asian semiconductor stocks:

  • Samsung Electronics (KS:005930) fell approximately 5.6%.
  • SK Hynix (KS:000660) declined about 7.3%.
  • Advantest Corp (TYO:6857) dropped more than 7%.
  • Tokyo Electron (TYO:8035) slipped 5%.
  • Taiwan Semiconductor Manufacturing Co (TW:2330) fell over 2%.

Overall, South Korean heavyweight chipmakers slumped between 8% and 10% in broader market commentary, while Japanese and Taiwanese peers also posted double‑digit percentage losses.

Market Implications

The news sparked a sector‑wide rotation, with investors pulling back from semiconductor exposure amid fears that AI‑related hardware demand may not accelerate as quickly as anticipated. The sentiment shift mirrors the earlier U.S. chipmaker sell‑off, underscoring the global sensitivity of chip equities to AI‑related efficiency breakthroughs and cloud‑service strategies.
