ASML Holding is trading at €1486.20, up +3.09%, amid AI and data-center demand and stronger semiconductor-sector sentiment.

  • AI and data-center demand lifted Asian chipmakers into September 21, 2026.
  • Nasdaq futures rose 0.73%, supporting broader technology risk appetite.
  • No new ASML-specific announcement dated September 18–21 clearly explains the move; Reuters’ latest company coverage is dated September 14 and does not attribute the rise to High-NA developments.
