Investors are pushing for a more attractive valuation to commit to the offering, with some viewing the recently discussed $US1.5 trillion ($A2.2 trillion) valuation as being at the high end of expectations, , four people familiar with investor discussions told Reuters.
The discussions reflect in part the impact of the sharpest technology stocks selloff in a year and geopolitical uncertainty clouding the outlook for new offerings.
Anthropic declined to comment on investor doubts.
The roadshow was initially expected to kick off the week of November 9, Reuters previously reported, with pricing expected the following week.
Anthropic may need to offer a bigger discount to secure investor commitments, particularly as investors recognise the company's need to raise capital given a record of quarterly losses and the large commitments it has made to partners in the AI buildout, the people said.
Investors are also eagerly awaiting Anthropic's October revenue figure, which the company left blank in its updated S-1 filing, to assess whether the AI lab has managed to boost growth after a slowdown in recent months, two of the people said.
Wall Street and Silicon Valley were abuzz on Thursday with questions about whether the company would move forward, in the wake of the two-day AI market selloff following Tuesday's US midterm elections.
A decision to delay the offering would likely fuel further concern over the health of the AI ecosystem at a time when the success of ballot efforts in many states limiting data centre development has crystallised political opposition to data centres and other aspects of AI.
An Anthropic delay could also pose a threat to the broader stock market, which is heavily weighted toward large technology firms whose valuations would likely be squeezed by any sense that Anthropic, one of the highest-profile AI firms, is finding it difficult to raise funds.
Many investors remain bullish on the AI buildout, though the selling in AI-related assets has dented sentiment over the past month. Some analysts say that Anthropic, like SpaceX before it, is likely to benefit from strong retail investor demand.
Even if Anthropic and its investors get together on a valuation, as Wall Street currently expects, other factors could determine whether the company chooses to move forward with the IPO by year-end.
If the market for AI-related assets remains under pressure, the company could decide to delay the offering until the market looks more resilient and likely to smoothly digest an offering that is expected by some to reach $US100 billion ($A144 billion), the people familiar with investor discussions said.
The Wall Street Journal reported on Thursday evening that IPO investors are sceptical Anthropic can achieve $US1.5 trillion ($A2.2 trillion) in valuation in a public listing.
Trading was anything but smooth on Thursday, fuelled by the outcome this week at the polls but also by corporate developments and increasing market anxiety.
