The Fifth Extension Arrived Exactly as Predicted. The Number That Follows It Is Smaller Than Today's.
Claude Code's fifth limit extension ran through Sept 13, as OneHuman predicted Aug 27. Sept 14's 'permanent' 25% increase nets a 17% cut from today's boost.
Published: September 12, 2026 Impact: High. Affects Claude Code subscribers on Pro, Max, Team, and seat-based Enterprise plans.
What I Said on August 27
BNA #23 closed with a specific instruction: plan for Claude Code's weekly-limit boost to end, and treat any fifth extension as a bonus, not something to build a schedule around. Published August 27, 2026, with the deadline then at August 31.
The fifth extension landed exactly as predicted, through September 13. What replaces it on September 14 amounts to a 17% cut from what subscribers have today.
Anthropic pushed the "temporary" 50% weekly-limit boost, live since May 13 for Pro, Max, Team, and seat-based Enterprise plans, through September 13, 2026, 11:59 PM PT. Its help center article, fetched directly, says only that limits "return to their standard levels" afterward, with "no change to your plan or billing." No percentage. No September 14. No mention of anything permanent.
The Number That Only Exists on X
The permanent replacement lives elsewhere. @ClaudeDevs posted on X, dated August 29 by independent outlet QCode.cc, that starting September 14, standard weekly limits rise permanently by 25% for Pro, Max, Team, and seat-based Enterprise plans. BleepingComputer, ITdaily, Windows Report, and Android Headlines converged on the same date and figure within days.
Anthropic has never published an absolute weekly-limit number for any Claude Code plan. The only public figures anywhere in this system are multipliers for a different throttle, the 5-hour session limit, where Pro is 1x and Max runs 5x or 20x. Every percentage here, 50%, 25%, the 17% below, is measured against a number Anthropic has never disclosed.
The Math
Illustrative baseline of 100, since no real published number exists:
| Point in time | Weekly limit (illustrative) |
|---|---|
| Original, pre-boost | 100 |
| Temporary boost (through Sept 13) | 150 |
| Permanent, from Sept 14 (25% over 100) | 125 |
125 is 25% above the original 100. It is also below the 150 subscribers have had since May. Net change from today: a 17% reduction.
BleepingComputer reported that Anthropic's first X post led with the 25% figure alone, drew criticism for omitting the net effect, was deleted, and was replaced with a clarification: "Compared to today, this works out to a 17% reduction in weekly limits on Claude Code." Neither Cowork nor I reached the raw X post to verify that wording directly. The quote belongs to BleepingComputer's reporting, not to OneHuman's own primary-source confirmation.
One Layer, Not Two
The 50%, the 25%, and the 17% above all concern the weekly limit only. The separate 5-hour session limit, the 1x/5x/20x system, is untouched.
What to Do Next
- Plan usage from September 14 onward around 125, not 150.
- The 25% change is not in Anthropic's help center. Its only durable record is a since-edited X post and the outlets that covered it.
- If a team sized its workflow to the boosted limit, re-check it against 125 before September 14.
Bottom Line
The fifth extension arrived exactly as predicted, through September 13. What follows holds too, in its own way: a 25% increase measured against a three-month-old baseline, a 17% cut measured against what subscribers actually have, and a disclosure durable enough only for a since-edited social post. Anthropic has never published the baseline these percentages are built on. That absence is the story, not the arithmetic.

"OneHuman said plan for the boost to end and treat a fifth extension as a bonus, not an assumption. The fifth extension came, on schedule, through September 13, 2026."
"Anthropic's own math: current boosted limit 150, new permanent limit from September 14 is 125. Net effect versus today: a 17% reduction, not a 25% increase."
"Anthropic has never once published an absolute weekly limit number for any Claude Code plan. Every percentage in this story is measured against a number the company has never disclosed."
"The 'return to standard levels' language sits in Anthropic's own help center. The 25% figure and the September 14 date exist only on X, nowhere durable."
