Wall Street Turmoil Casts Uncertainty Over Anthropic’s Billion-Dollar IPO Plans

Anthropic’s planned stock market debut faces growing uncertainty after a major Wall Street sell-off unsettled investors and weakened enthusiasm for artificial intelligence companies.

The technology-focused Nasdaq Composite suffered its largest single-day loss in dollar terms on Thursday, November 5, shedding approximately $2.5 trillion in market value. Technology shares bore much of the damage as investors reassessed the scale and financial sustainability of the artificial intelligence boom. The downturn also spread beyond the United States, with Asian and European markets following the decline on Friday. The sudden reversal has created a difficult backdrop for Anthropic as it prepares to approach investors ahead of a potential public listing.

Anthropic had been expected to pursue one of the largest initial public offerings in financial history, with market expectations pointing towards a valuation of about $1.5 trillion. However, the latest market turbulence has prompted speculation that the company may need to reduce its proposed valuation or postpone the flotation. Neither outcome had been confirmed by the company at the time of the reports.

The shift in expectations was reflected in prediction-market activity. Before the US midterm elections, traders on Kalshi had placed the probability of Anthropic completing its IPO during November above 90 per cent. Following Thursday’s market decline, that figure dropped to 60 per cent, highlighting how quickly confidence in the proposed timetable had weakened.

Mike O’Rourke, chief market strategist at JonesTrading, said he believed Anthropic could still proceed with its listing but might have to accept a lower valuation. His assessment reflects concerns that investors could become more cautious about paying premium prices for businesses whose growth depends heavily on continued expansion in artificial intelligence infrastructure.

The timing is particularly challenging because Anthropic was expected to begin its pre-IPO roadshow shortly. During this process, company executives and advisers meet prospective investors, explain the business and gauge demand before deciding on the final share price. A weaker reception could affect both the amount the company raises and the valuation it can secure.

The wider market sell-off has also exposed doubts about the financial returns from the enormous investment being made in artificial intelligence. Technology companies have committed vast sums to data centres, specialist computer chips and energy infrastructure, but investors are increasingly questioning whether demand for AI services will grow quickly enough to justify the spending.

Political developments have added another complication. The US midterm elections delivered significant gains for Democrats, including candidates critical of the rapid expansion of data centres. Opposition to new developments has become a concern for technology companies because the infrastructure required to run advanced AI systems depends on access to land, electricity and planning approvals.

The election results initially appeared to have little impact on market confidence, with shares reaching fresh highs on Wednesday after the Democratic victories and comments from President Donald Trump about working with the opposition. However, investors reassessed the implications for data centre construction the following day, contributing to the sharp reversal in technology stocks.

Anthropic had already identified potential restrictions on data centre development as a risk in its regulatory paperwork. The company’s latest disclosures also highlighted the scale of its future infrastructure commitments, adding to questions about how it will finance the computing capacity required to support its expansion.

An updated filing revealed commitments approaching $900 billion for computing power and data centre infrastructure over the coming years. This figure is substantial when compared with the $132 billion in cash and investments the company held a month earlier. The commitments underline the extent to which Anthropic’s future growth depends on securing the necessary computing resources and the financing arrangements behind them.

Investors are also examining whether the expected growth in AI demand will be sufficient to support such large financial obligations. A slowdown in infrastructure development, higher financing costs or delays in bringing computing capacity online could affect the company’s ability to meet its expansion plans and maintain the growth expectations underpinning its proposed valuation.

The debate is not limited to Anthropic. Its flotation is expected to provide an important indication of how public-market investors value the wider artificial intelligence sector. The outcome could influence expectations for other major AI businesses considering stock market listings, including rival OpenAI.

Market commentators have also begun reassessing forecasts for technology spending. Dan Ives, a prominent technology-sector analyst, said he now expected the rapid growth in major technology companies’ AI spending to peak in 2027, rather than in 2028 or 2029. He maintained a positive long-term view of the sector but said investors would need to be more selective about which businesses and industries were likely to perform best.

Anthropic has not confirmed whether the market disruption will change its IPO timetable or pricing plans. The company did not immediately respond to a request for comment on the latest developments. For now, its proposed flotation faces a combination of market volatility, political uncertainty and questions about the cost of building the infrastructure needed to power its technology.

The coming weeks will be important in determining whether Anthropic can maintain investor confidence and proceed with its anticipated public offering. A successful listing could reinforce belief in the long-term commercial prospects of artificial intelligence, while a delay or substantially reduced valuation could signal a more cautious period for the sector.
