Mary Pieterse-Bloem on Anthropic’s IPO: ‘It will be a spectacular stock market debut’

The prospectus Anthropic has filed in preparation for its planned initial public offering (IPO) contains extensive warnings about the risks associated with its AI technology and financial position. Nevertheless, Pieterse-Bloem expects considerable investor interest. ‘It will be a spectacular stock market debut, whatever happens,’ she told Dutch public broadcaster NOS en BNR Nieuwsradio.

According to Pieterse-Bloem, Anthropic has developed particularly promising technology with its AI model, Claude. The model performs especially well in programming and coding, and is already widely used at universities and banks. The technology could help organisations automate tasks, reduce workloads and cut costs.

Promising technology, but not yet profitable

Anthropic reported losses running into tens of billions of dollars in 2025, despite strong revenue growth. Pieterse-Bloem argues that these losses need to be viewed in the context of the company’s stage of development. ‘This is promising technology that is not yet profitable,’ she says. She sees parallels with the recent stock market debut of SpaceX. In that case, too, investors were drawn to technology with significant growth potential, even though the share price fell back after an initial surge. Anthropic’s planned IPO illustrates investors’ willingness to look ahead and place their confidence in the future potential of AI.

Pieterse-Bloem also regards Anthropic’s decision to publish its prospectus at this stage as a sign of confidence in the success of the flotation. The company appears to believe that market conditions will remain favourable in the near term and that investors will embrace its business model.

Acknowledging the risks of AI

Anthropic’s prospectus warns, among other things, that its AI models could be misused to develop dangerous weapons. The company also highlights financial risks and its reliance on a relatively small number of major customers. 

Pieterse-Bloem considers it a positive sign that Anthropic explicitly acknowledges the potential dangers of its technology. This does not eliminate the risks, but recognising them is important, she argues. ‘And if Anthropic doesn’t do it, another company will. Better the devil you know than the devil you don’t,’ she told NOS.

The planned IPO therefore brings two developments into focus: investors’ strong confidence in AI’s economic potential and growing awareness of the risks associated with the technology.
