Anthropic plans to identify negative sentiment toward artificial intelligence (AI) and data centers as risk factors in its initial public offering (IPO) prospectus, people familiar with the matter told CNBC. The filing is expected within weeks after the company filed confidentially in June and held preliminary meetings with bankers and investors in San Francisco. The prospectus is expected to warn that public opposition to new data-center projects could affect the infrastructure needed to support AI growth. Chief Financial Officer Krishna Rao is also answering questions about competition and margin pressure from open-source models, as well as the potential impact of slower data-center construction. That issue is significant because compute capacity is closely tied to revenue at AI labs. Anthropic’s annualized revenue run rate exceeded $65 billion in July, about $25 billion more than OpenAI’s, while the company’s private-market valuation is nearly $1 trillion. Investors expect a public float of around $2 trillion. BeInCrypto reported that Anthropic expects its IPO to match or surpass SpaceX’s record stock-market debut. Public opposition to AI data centers has risen: a March Gallup survey found that 7 in 10 Americans opposed a local AI data center, including 48% who were strongly opposed, while an August 8-13 Heatmap Pro poll of 2,045 registered voters conducted by Embold Research put opposition at 75%, up from 42% a year earlier. Pew Research found that 71% of adults expect AI to reduce U.S. jobs over the next two decades, compared with 64% in 2024. Political responses include Pennsylvania Governor Josh Shapiro’s executive order imposing strict data-center development standards and New York Governor Kathy Hochul’s pause on permits for large new data centers.
