Anthropic investors shop IPO shares at a premium

Some Anthropic backers are trying to sell part of their expected allocations in the company's initial public offering before the stock begins trading. They are asking new buyers to pay more than the offering price. JonesTrading Institutional Services is marketing a block of Anthropic shares worth up to $500 million for investors who expect large allocations, Bloomberg reported on November 10. Buyers would pay a fee of 3% to 5% on top of the final IPO price.bloomberg.com

These pre-trading deals show how much demand investors expect for what Bloomberg called the largest public listing on record. The offer appeared on the same day the Claude maker set terms for the deal.bloomberg.com

IPO terms set

In an updated filing on Tuesday, Anthropic said it would offer 825 million Class A shares priced between $70 and $78 each, CNBC reported. The company also started its roadshow to market the deal. At the top of the range, the sale would raise as much as $64.4 billion and value the company at about $1.4 trillion on a fully diluted basis, according to Reuters. The shares are expected to begin trading on the Nasdaq ↗ 1.40% on November 19 under the symbol "ANT."reuters.com+2

Anthropic will also raise $26 billion through a separate private placement with cornerstone investors, Reuters reported. Those investors include Alphabet's ↘ 0.38% Google, Nvidia ↘ 5.47% and Advanced Micro Devices ↗ 1.30%. Underwriters led by Goldman Sachs The Goldman Sachs Group, Inc. ↗ 0.44% and Morgan Stanley ↗ 0.25% can buy up to 123.75 million more shares, and up to 20% of the offering is expected to go to retail investors, TechCrunch reported.techcrunch.com+1

A lower valuation than expected

The range comes in well below the $2 trillion valuation some outlets had reported weeks earlier, and it arrives during a sell-off in AI stocks, Fortune noted. Reuters said the valuation fell slightly short of what some investors had expected, which makes the deal a test of Wall Street's confidence in the AI boom.fortune.com

Late on Monday, the run-up to the listing hit a snag. Anthropic briefly sent banks a filing that showed a raise of up to $69.3 billion at $70 to $80 a share, then retracted it and said the pricing details were inaccurate, Reuters reported.reuters.com

Strong growth, heavy commitments

Anthropic's revenue rose to $33.2 billion in the first nine months of 2026, and the company has committed to spending about $895.4 billion, mostly on compute and infrastructure, Yahoo Finance reported. Its run-rate revenue was about $81 billion as of October 31, according to Reuters.finance.yahoo.com+1

Buyers in the JonesTrading block would be betting that demand for the shares holds up once trading starts. Paying 3% to 5% above the IPO price only makes sense if the stock opens higher than that.
