ASML's China chip threat appears overstated as €55B market swing rattles investors

Markets had a brief panic. Roughly €55 billion in market value evaporated from ASML after reports surfaced that a state-linked Shanghai firm had begun mass-producing domestic immersion Deep Ultraviolet lithography machines. ASML shares dropped over 5% in late July 2026.

What actually happened

The Shanghai entity in question reportedly achieved mass production of DUV lithography machines, which are a category of chip-making tools that ASML also produces but considers something of a legacy product compared to its flagship Extreme Ultraviolet systems. DUV machines make older, less advanced chips. EUV machines make the cutting-edge stuff that powers modern AI processors.

The domestic machines are reportedly being prepared for delivery to major Chinese chipmakers including SMIC, Hua Hong Semiconductor, and ChangXin Memory Technologies by 2026. But analysts who have looked at the specifications argue that the rival technology does not match what ASML actually ships.
