OpenAI announced ChatGPT Pro 500, a $500/month subscription tier, on September 29, 2026. Will Anthropic follow suit with its own higher-priced plan? OpenAI Help Center

Resolves YES if, after this market opens and before January 1, 2027, at 00:00 CET (UTC+1), Anthropic officially announces a new individual subscription tier with a standard U.S. price of at least $400/month, excluding taxes.

The announcement must confirm the price, but the subscription need not become available before the deadline. API billing, usage-based top-ups, and team or enterprise contracts do not count. Anthropic does not need to explicitly describe the tier as a response to OpenAI.

Otherwise, resolves NO

This market closes early on December 1st 2026 it will not resolve NO until January 1st.
