Anthropic to sell IPO shares to UK retail via RetailBook

The significance here is structural rather than financial: a high-profile AI issuer is testing the UK's Public Offer Platform as a route to retail participation without the cost and disclosure burden of a full prospectus. That makes this a live experiment in how cross-border retail access to major tech listings is engineered, and other platforms feeding orders through RetailBook will be watching closely. With the plans explicitly not final, the open question is whether the POP route survives to listing, and whether its prospectus exemption becomes a template others copy.
