Claude usage limit changes: a dated timeline

Last checked: September 15, 2026.

Anthropic changes Claude's usage limits every few months, and never from one single page. Below is every dated change we could verify against Anthropic's own posts or a named outlet quoting them directly, newest first.

The timeline, most recent first

September 14, 2026 — a "25% increase" that was a 17% cut for current users

Anthropic made Claude Code's weekly limits permanently 25% higher than their original 2025 baseline, for Pro, Max, Team and seat-based Enterprise. The catch: a temporary 50% boost had been running since May, and it expired the day before. Anyone using that boost woke up to roughly 17% less weekly Claude Code capacity than they'd had all summer — a fact Anthropic confirmed only after users and journalists pushed back on the "increase" framing. Five-hour session limits weren't touched.

May 13, 2026 — a "temporary" 50% weekly boost, extended more than once

Anthropic raised Claude Code's weekly limits 50% above baseline, calling it temporary and citing infrastructure headroom. It was due to end July 13, then got extended more than once, ultimately running through September 13, 2026 at 11:59pm PT — the boost the September 14 change above replaced. Covered Pro, Max, Team and legacy seat-based Enterprise; excluded Free and consumption-based Enterprise seats.

May 6, 2026 — Claude Code's five-hour limits doubled

Announced alongside a compute deal with SpaceX: Claude Code's five-hour session limits doubled for Pro, Max, Team and seat-based Enterprise, and the "peak hours" limit reduction was removed for Pro and Max. This is the one resizing of the base five-hour window itself, rather than a weekly cap or a short promo.

March 13–27, 2026 — a two-week off-peak doubling promo

A time-limited promo doubled five-hour session limits roughly 8am–2pm ET each day, across Free, Pro, Max and Team, and across claude.ai, the desktop and mobile apps, Claude Code, Claude for Excel and Claude for PowerPoint. Not a permanent change — it lapsed on schedule.

August 28, 2025 (announced July 28) — the first weekly limits

Before this, paid plans had only the five-hour session window. Anthropic added two weekly caps on top of it, one overall and one specific to the Opus model, for Pro and Max. Anthropic estimated fewer than 5% of subscribers would notice, and pointed to accounts running Claude Code continuously in the background, 24/7, as the reason. In the announcement itself, Anthropic gave hour ranges (not message counts): Pro got roughly 40–80 hours of Sonnet 4 a week; the $100 Max plan got 140–280 Sonnet 4 hours plus 15–35 Opus 4 hours; the $200 Max plan got 240–480 Sonnet 4 hours plus 24–40 Opus 4 hours. Those ranges were specific to that announcement and haven't been repeated since.

April 9, 2025 — the Max plan launches

Anthropic introduced Claude's first tier above Pro: $100/month for 5x Pro's usage limits, $200/month for 20x, plus priority access to new models and features. Every weekly-limit change above only exists because Max created a heavier-usage tier for Anthropic to manage.

The pattern so far

Claude Code gets touched most. Four of the six changes above targeted Claude Code specifically, not claude.ai chat generally.
Promos expire; increases usually don't. The March 2026 doubling and the May 2026 weekly boost were both announced as temporary from day one. The May 2026 five-hour doubling and the 2025 weekly limits were framed as standing changes.
"Increase" and "decrease" depend on your baseline. September 2026 is the clearest example: a real percentage increase over the original limit, and a real percentage cut from what heavy users had gotten used to. Both were true at once.
The five-hour window is the one constant. It's been resized, but it's outlasted every weekly cap and promo layered on top of it.

Questions people ask

Has Anthropic reduced Claude's usage limits?

Once, in effect: the September 2026 change was announced as a permanent 25% increase to Claude Code's weekly limits, but it replaced a temporary 50% boost that had been running since May, so anyone using that boost saw about 17% less weekly capacity the next day. Every other change on this page has been an increase or a time-limited promo.

Do these changes apply to claude.ai chat, or just Claude Code?

Most of the 2026 changes (the March promo, the May doubling, the May and September weekly adjustments) targeted Claude Code specifically. The August 2025 weekly limits applied to the whole plan, chat included, on Pro and Max.

Where does Anthropic announce limit changes?

There's no single changelog. Anthropic mixes anthropic.com/news posts, X posts, and quiet in-product changes, and some of the clearest numbers (like the 17% net cut in September 2026) only surfaced after journalists pressed for them. That's why this page exists.

Has the five-hour session limit itself changed?

It's been resized once, doubling for Claude Code in May 2026, but the five-hour rolling window has been the base unit since Claude's usage limits began. Most of the changes on this page are weekly caps and temporary promos layered on top of it.
