Anthropic's unusual IPO lock-up: insiders can sell only 10% on day one
shashib · x · 2026-10-29
Anthropic's S-1 filing reveals a highly unorthodox post-IPO lock-up structure. Unlike the typical 3-6 month lock-up, non-founder directors, officers, and certain current/former employees can sell at most 10% of their shares on day one, another 35% after full-year 2026 results, while other shareholders unlock in waves starting 27 days after the prospectus filing. Commentators say the plan will test investor confidence: Anthropic has shown enterprise demand, but investors doubt whether AI spending will deliver returns.
