Anthropic has tied recent Claude usage limit resets to new model releases, most recently issuing a banked reset for Pro, Max, and Team subscribers alongside the September 22, 2026 launch of Opus 5.5, which also raised five-hour session limits by 20 percent. This follows full resets on September 4 for Max plans and September 1 for all users after the Fable 5.1 rollout, reflecting Anthropic’s pattern of using resets to manage demand during high-usage periods or competitive pushes against rivals like OpenAI and Google. A September 14 policy shift made a 25 percent permanent increase to Claude Code weekly limits after a temporary 50 percent boost expired, while rolling five-hour and account-specific weekly caps remain the core constraints. Traders watch for announcements around developer events or capacity expansions, as these directly influence reset frequency and subscriber experience.
