The Information reported on Thursday that Anthropic is considering requiring
rank-and-file employees to sell shares under pre-set trading plans after an IPO
to avoid insider-trading concerns. The company may require all employees to use
10b5-1 plans—typically limited to executives and some finance/legal staff—which
specify timing, quantity and price on a preset schedule. Discussions between
Anthropic executives and external advisers are ongoing and no decision has been
made. Anthropic is also weighing how many shares existing shareholders could
sell on the IPO day and the length of the post-IPO lockup.
