Anthropic IPO heavily overbooked, retail investors face tough allocation odds

Heavy demand for the IPO could push the final price above the initial $70 to $78 range, increasing the total funds raised and the company's market value. Those retail investors who receive no shares may add to buying pressure once trading begins, which could lead to a sharp first-day jump and subsequent volatility. The strong retail enthusiasm makes the debut a gauge of sentiment for AI and growth stocks after a period of selling. A weak first session would hurt the sector, while a strong one could help restore risk appetite toward the end of the year.

• Anthropic IPO targets around $1 trillion valuation, half the $2 trillion once whispered
• Anthropic IPO oversubscribed several times ahead of record $90 billion listing
• Anthropic reserves up to 20% of its $64 billion IPO for retail investors

Anthropic is setting aside a larger portion of its IPO for individual investors than is typical, but because orders are roughly six times the available shares, most retail buyers will receive only a small amount or none at all. They will then have to decide whether to purchase shares when trading opens.

A maximum of 20% of the 825 million shares being offered is reserved for retail investors, compared with the usual 5% to 10% in large US IPOs. The shares can be accessed through the underwriting banks and platforms such as Schwab, Fidelity, Robinhood, SoFi and E*Trade. The offering is reportedly about six times oversubscribed, with priority given to existing backers. Each broker has its own requirements: Fidelity demands at least $25,000 in assets, Schwab $50,000, and allocations may be proportional, in fixed lots or determined by a lottery. Submitting a request does not guarantee shares, and investors must be ready to take every share they ask for. Selling too quickly can limit access to future offerings.

Summary:

• Up to 20% of the 825 million shares on offer is set aside for retail investors, against a typical 5% to 10% in large US IPOs
• Shares are available through the underwriters and through Schwab, Fidelity, Robinhood, SoFi and E*Trade
• The offering is reportedly about six times oversubscribed, with existing backers prioritised
• Broker rules vary: Fidelity requires $25,000 in assets and Schwab $50,000, and allocations may be pro rata, fixed or by lottery
• Requests are not guaranteed, buyers must be ready to take every share they request, and fast flipping can limit future access
• US IPOs have risen almost 20% on average on day one since 1975, a gain that mostly goes to those allocated shares at the offer price

Since the 1970s, the average first-day gain for US IPOs has been nearly 20%, with the benefit flowing mainly to those who receive shares at the offer price. One research firm estimates that retail investors could purchase a record $250 million of Anthropic stock on its first trading day, more than double the retail buying during SpaceX's debut in June. Buying at the opening price means paying any first-day premium on top of an already high valuation relative to revenue. Historically, the most richly valued IPOs have underperformed in the years that follow.

The key takeaway is that a bigger retail allocation increases access but does not guarantee a good entry point. In 2021, Robinhood set aside a large portion of its own IPO for its customers, and the shares fell below the offer price on the first day. Even popular offerings can disappoint early buyers.
