Anthropic sets up to 20% of IPO shares for retail investors

Anthropic plans to allocate up to 20% of its IPO shares to retail investors, far exceeding the typical 5% to 10% range, according to an amended S-1 filing posted on Nov. 10. The final amount depends on demand, with up to roughly 165 million shares worth about $12.2 billion at the $74 pricing midpoint. The company behind Claude expects a total offering of about $61 billion, with approximately $59 billion going to the company, implying a post-IPO valuation above $1.3 trillion. The retail allocation ceiling mirrors recent large listings, though Robinhood set aside 25% in 2021 and SpaceX cut its planned 30% to the low 20% range after institutional demand surged. Access does not guarantee a filled order, as brokers use pro rata, fixed amount, or lottery systems, and some platforms restrict flipping shares within 15 days. Investors should evaluate the business fundamentals, including $33.2 billion in nine-month revenue against $900.9 billion in computing commitments, rather than focusing solely on allocation size.
