In March 2026, Anthropic was seriously considering a drastic move: removing Claude Code from its $20 Pro plan. The surge in developer usage was overwhelming their existing infrastructure.
What stopped them? SpaceX. On May 6, 2026, the Colossus 1 data center deal was formalized — 220,000 NVIDIA GPUs now flow directly to Pro and Max subscribers.
What exactly changed?
Claude Code usage limits have two layers: a 5-hour rolling window and a weekly cap. This announcement changed only the 5-hour window. The weekly cap stays the same.
Here's what "doubled" means in concrete numbers:
But the bigger change is the permanent removal of peak-hour throttling. Previously, Pro and Max users saw reduced limits on weekdays from 8am–2pm ET. You'd try to work during work hours, and your AI tool would say "too busy right now." That's gone permanently.
What was peak-hour throttling?
A temporary measure Anthropic introduced in March 2026 to manage capacity pressure. Pro and Max subscriber limits were automatically reduced during weekday 8am–2pm ET. With the SpaceX deal expanding infrastructure, it was permanently removed on May 6, 2026.
About the scale of the SpaceX deal: Musk had publicly called Anthropic "evil" just months earlier, then called them "highly competent" on the day the deal was announced. The context: SpaceX's upcoming IPO needed a high-profile anchor tenant for the Colossus 1 data center.
How much does doubling the window actually matter?
The numbers look impressive, but the real impact depends heavily on your workflow type.
| Before (March–May 2026) | After (May 6, 2026+) | |
|---|---|---|
| Pro 5-hour limit | ~225 messages | ~450 messages |
| Max 5x 5-hour limit | ~1,125 messages | ~2,250 messages |
| Max 20x 5-hour limit | ~4,500 messages | ~9,000 messages |
| Weekday 8am–2pm ET | Limits automatically reduced | Full limits all day |
| MCP-heavy sessions | Throttled mid-session | Stable through entire window |
| Weekly cap | Unchanged | Unchanged (no change) |
MCP-heavy workflows feel the change most. Each MCP task requires 5–10 API calls — draining limits 5–10x faster than regular chat. Before, morning sessions hit throttling mid-way. Now the entire window runs without interruption.
The honest caveat: since weekly caps didn't change, you can now burn through them faster. If you max out your 5-hour window every session, you'll hit the weekly ceiling sooner.
Watch your weekly cap
The wider 5-hour window makes the weekly limit easier to exhaust. If you're running Max 5x or 20x at full throttle daily, check your weekly cap first. Use /status in Claude Code to check remaining limits in real time.
The essentials: choosing your plan
- Pro ($20/month) — Casual daily users
Under 1–2 hours of Claude Code per day, focused on Q&A, reviews, and light automation. Post-May, Pro works well as a "serious-user entry point." Peak throttling is gone, so mornings are smooth. - Max 5x ($100/month) — Heavy developers
2–4+ hours of Claude Code daily, or long agentic runs. MCP-heavy sessions, code review automation, and multi-file refactors run stably here. - Max 20x ($200/month) — Agent team operators
Running agent teams or keeping Claude Code open all day. Up to 9,000 messages per 5-hour window — 20x the Pro limit. - Pay-per-token API — Production developers
Token-based usage without subscription. API Tier 1 input tokens per minute increased 1,500%, output 900%. If Claude Opus powers your production pipeline, this is the real change. - Checking your limits — No setup required
Already on Pro or Max? Changes applied automatically from May 6. Run/statusin Claude Code to check remaining limits.
