Resolves to the date range of Anthropic announcing their next funding round. The previous round, as of market creation, was their series E. It does not have to explicitly be called a Series F.

IPO, acquisition, the company going bust, and the sun engulfing the earth all resolve n/a.

"Announce" means an employee speaking in an official capacity to the press/on social media/on the Anthropic website -- rumors do not count.
