ASML has confirmed that a group of disgruntled workers is pushing back hard against an invitation for Elon Musk to address the equipment maker’s closed annual tech conference in Den Bosch this Thursday. According to Dutch publication Eindhovens Dagblad (via DutchNews), employees have been airing their grievances on the company’s internal comms platform, with several threatening to skip his appearance altogether because of his involvement in U.S. politics and what staff described as "Nazi sympathies."

If the invitation is accepted, Musk could join CEO Christophe Fouquet by video link to discuss AI, robotics, space exploration, and semiconductor production, with the conversation centered around Terafab, the SpaceX and Tesla chip venture whose proposed Texas fab can’t reach production without ASML's machines.

Backlash began to surface on Viva Engage, ASML’s internal employee platform, where workers have argued that giving the controversial tech leader a platform clashes with the company’s stated commitment to an inclusive culture. In particular, ASML staff have specifically highlighted Musk’s political activities around the Trump administration, general anti-European rhetoric, and what staff described as “Nazi sympathies.” In March, an Amsterdam court banned the Grok image-generation app due to its abusive “undressing” image generation capabilities.

ASML is the sole monopoly supplier of EUV lithography systems, the tools needed to pattern transistors at the leading edge; fabs targeting advanced nodes have no viable alternative.

Every major foundry and memory maker, including TSMC, Samsung, SK hynix, Micron, and Intel, already holds orders with the company. Terafab, by contrast, has no path to leading-edge production that bypasses ASML, and the company’s CEO said last month that Musk is "very serious" about the project, noting that ventures like Terafab and Starlink would strain equipment makers' capacity over the coming years.

ASML hasn’t addressed the internal revolt directly, saying only to employees via Viva Engage that it’s committed to a workplace where everyone feels respected and is free to express their opinion.

Musk announced Terafab in March as a SpaceX and Tesla joint venture with an initial $20 billion budget, targeting 2nm production and a terawatt of annual compute for AI, robotics, and orbital data centers. SpaceX has since filed a property tax abatement application in Grimes County, Texas, for a fab costing $55 billion in its initial phases and up to $119 billion if all expansions proceed, with Intel set to contribute its 14A process technology. Outside estimates run higher, with Bernstein analysts arguing the full terawatt project would require roughly 358 fabs and around $5 trillion.

“ASML regularly invites technology leaders from the industry to share their insights. The invitation to Elon Musk took place in the context of the Terafab project, which is highly relevant to the semiconductor industry,” the company said.
