What to know first
This timeline only includes entries that can be checked on OpenAI or Anthropic official blogs, help centers, release notes or official X accounts, dated as the source shows. Each entry says whether the price changed, which region it covers and what kind of source it comes from, so you can tell a price change from an allowance change or a new plan. Third-party reports and changes whose date cannot be checked on an official page are left out.
What official price and plan changes have ChatGPT and Claude made?

How did ChatGPT Pro tiers change in 2026?
In April 2026, OpenAI added a $100-a-month Pro tier alongside Pro 200. On September 29 it launched Pro 500 at $500 a month, reopened Pro 200 to new subscriptions and announced allowance changes by email. On October 29 that cut was canceled: Pro 200 subscribers who already had the higher allowance kept it, those with the lower allowance were doubled to match, Pro 100 and Pro 500 Work and Codex allowances doubled, and Plus usage stayed the same.
The Help Center now lists three tiers, Pro 100, Pro 200 and Pro 500, at $100, $200 and $500 a month, billed monthly only, with Ultrafast only on Pro 500. See the Pro 200 allowance change explainer for details and ChatGPT prices by region.

Did Claude prices change when Max 20x became Ultra?
No. Anthropic's rename announcement says Max is still $100 a month and Ultra is still $200, and subscribers do not need to do anything. From the day of the announcement, most existing verified Ultra accounts lost the 5-hour limit; newer accounts keep a temporary limit until they are verified, and weekly limits are unchanged. The Help Center says Max 20x subscribers move to Ultra automatically with no price change.
The pricing page now lists Pro at $20 a month or $17 a month billed annually ($200 up front), with Max and Ultra billed monthly only and prices excluding tax. Compare the tiers in Claude Pro vs Max vs Ultra and see Claude prices.
