On May 13, 2026, Anthropic raised Claude Code's weekly usage limits by 50 percent for every paid plan. There was no press release, no product launch event. The change went live quietly, but the timing was anything but coincidental: on the same day, OpenAI's developer account published a direct offer of two months of free Codex access to enterprise customers willing to switch from Claude Code within thirty days. Both companies were staking out territory in the same space at the same moment, and Anthropic answered a capacity pitch with a capacity increase.
The move followed Anthropic's announcement just one week earlier, at the Code with Claude conference in San Francisco, that it was doubling Claude Code's five-hour rate limits across all paid tiers. Taken together, the two changes gave Claude Code users twice the short-window throughput and half again as much weekly budget, all without a price increase and with nothing users had to configure. The higher weekly ceiling is set to hold through July 13, 2026 at 6 PM Pacific.
What the Increase Covers
The new weekly limit applies to Pro, Max, Team, and seat-based Enterprise plans. It goes into effect everywhere Claude Code runs: the CLI, IDE extensions (VS Code, JetBrains), the desktop application, and the web interface. Anthropic also removed the peak-hours limit reduction that previously throttled Pro and Max accounts during high-traffic periods, a friction point developers had raised repeatedly in forums and support tickets.

The Competitive Pressure Behind the Move
The trigger for both the doubled five-hour limits and the 50 percent weekly increase is a specific technical gap. Third-party benchmarkers have published data suggesting that OpenAI's Codex model consumes roughly 4.2 times fewer tokens to complete equivalent coding tasks compared with Claude Code running on Claude Opus 4.7. For engineering teams billing by token volume, that differential compounds fast. The more a team codes, the more the math pushes toward switching.
Anthropic does not appear to be contesting the efficiency claim directly. Instead, the company is shrinking the practical impact of the gap by expanding what users can do before hitting limits. A team that was running tight at the end of a sprint now has considerably more room. OpenAI's simultaneous offer, two months of free Codex access targeted at CTOs of enterprise Claude Code customers, with a 30-day window to respond, made the competition explicit in a way that had previously been implicit.
"Anthropic doubled the 5-hour limits last week. Combined, that is a 2x boost to your short-window quota and a 1.5x boost to your weekly cap, all live at the same time, all without a price increase." apidog, analysis of Claude Code limit changes, May 2026
The Compute Foundation
The expanded limits are possible because of what Anthropic secured at the Code with Claude SF conference: an agreement with SpaceX to use the full capacity of the Colossus 1 data center in Memphis, Tennessee. That deal covers more than 300 megawatts of power and more than 220,000 NVIDIA GPUs, representing one of the largest single-site AI compute agreements announced this year. The new capacity began flowing into the developer tier almost immediately, enabling the rapid back-to-back limit increases.
Anthropic is now running the Code with Claude conference series through London, where developer sessions wrapped May 20-21, and on to Tokyo in June. The company needed to give developers attending those events something concrete. A Claude Code environment where limits are visibly less constraining is a more persuasive argument than a benchmark slide, and the timing of the limit increases was not accidental on that front either.
What Comes After July 13
The current limit increase has a defined end date. Whether Anthropic extends it, makes it permanent, or rolls it back depends partly on how Colossus compute provisioning proceeds and partly on how the competitive picture with Codex develops over the next two months. Anthropic has made no commitment beyond July 13, and the temporary framing gives the company the option to reprice or restructure limits once the immediate competitive pressure is assessed.
For developers, the practical reality right now is that the ceiling is higher than it has ever been, and the SpaceX-backed compute expansion gives Anthropic more headroom to sustain that level than it had six months ago. Whether the token-efficiency gap with Codex eventually narrows through model improvements or usage pricing changes is the longer-term question. The limit increase through July buys Anthropic time to answer it.
