[Sources: Anthropic Investors Pre-Sell IPO Share Allocations at 3% to 5% Premium] According to sources familiar with the matter, some investors are pre-selling their expected IPO share allocations to other institutions ahead of Anthropic's listing. JonesTrading Institutional Services LLC is promoting a deal worth up to $500 million in Anthropic stock on behalf of some investors expecting substantial allocations, with buyers paying an additional 3% to 5% on top of the final IPO price. Sources indicated that such transactions help institutions mitigate some of their holding risk, as the shares are not subject to IPO lock-up periods, but buyers still need approval from the sellers and banks participating in the IPO. In addition, another seller is selling existing Anthropic shares worth over $1 billion through a special purpose vehicle (SPV) at a valuation of $1.4 trillion to $1.6 trillion, charging an additional fee.
