European Chip Stocks Rally on Anthropic's Projected $518 Billion AI Spending

European semiconductor stocks gained broadly on Tuesday after reports on AI startup Anthropic's initial public offering (IPO) prospectus revealed enormous future spending commitments, boosting investor optimism for sustained demand in the artificial intelligence sector.

Sector-Wide Rally

The positive sentiment lifted chip-related companies across the continent. Gains were seen in semiconductor equipment makers, foundries, and designers, highlighting the interconnected nature of the industry's supply chain.

Notable movers included:

• X-Fab Silicon Foundries rose 6.5% in Paris.
• Technoprobe climbed 6.3% in Milan.
• ams OSRAM gained 5.9%.
• ASML Holding, a key equipment supplier, advanced 3.2% in Amsterdam.
• Infineon Technologies in Germany was up 3.1%.

AI Spending Fuels Demand Outlook

The rally's catalyst was a detail from Anthropic's prospectus, which, according to Investing.com, forecast $518 billion in obligations for cloud, computing, and infrastructure over the next year. This figure underscores the immense capital investment required to develop and operate advanced AI models.

For investors, such large-scale spending directly translates into higher demand for the processors, memory chips, and manufacturing equipment that European firms produce. The disclosure provides a tangible forecast for the infrastructure build-out that has been a primary driver of the semiconductor industry's growth.

A Look Inside Anthropic's Finances

While the spending outlook is a positive signal for suppliers, the prospectus also sheds light on the high costs of competing in the AI arms race. According to a Reuters report cited by the source, Anthropic's revenue grew twelvefold to nearly $4.6 billion in 2025, but the company also reported a net loss of $42 billion, which included a significant accounting charge.

The company's spending on computing and infrastructure tripled in 2025 to $7.33 billion, leading to an operating loss of over $8 billion. Anthropic's potential listing, expected after the U.S. midterm elections, is seen as a critical test of investor appetite for capital-intensive AI companies and could set a valuation benchmark for the sector.
