Anthropic and SpaceX Partner to Double Claude Code Rate Limits via Colossus 1

Overview

Anthropic announced a major compute partnership with SpaceX on May 6, 2026, securing access to the entire compute capacity at SpaceX's Colossus 1 data center in Memphis, Tennessee. The agreement provides more than 300 megawatts of new capacity — equivalent to over 220,000 NVIDIA GPUs — deployable within the month.

Immediate Rate Limit Changes

Claude Code five-hour rate limits: doubled for Pro, Max, Team, and seat-based Enterprise plans

Peak-hours limit reduction: removed immediately for Pro and Max accounts

Claude Opus API rate limits: significantly raised

About SpaceX Colossus 1

Colossus 1 is SpaceX's AI supercomputer facility located in Memphis, Tennessee. Under this agreement, Anthropic gains access to all of Colossus 1's compute capacity. The two companies have also expressed mutual interest in developing multiple gigawatts of orbital AI compute capacity in space.

Broader Infrastructure Strategy

This SpaceX deal is part of Anthropic's larger compute expansion. The company has also arranged an up to 5 gigawatt agreement with Amazon, a 5 GW deal with Google and Broadcom, a $30 billion Azure capacity partnership with Microsoft and NVIDIA, and a $50 billion American AI infrastructure investment with Fluidstack.

Significance

Notably, Elon Musk's SpaceX is now providing compute power for one of OpenAI's main competitors, despite Musk's ongoing legal disputes with OpenAI. The announcement arrives ahead of Anthropic's anticipated June 2026 IPO and delivers immediate throughput gains for Claude Code developers and enterprise customers running demanding agentic workflows.
