OpenAI Codex hits 7M users, 10x growth in 6 months, likely overtaking Claude Code

[AINews] Codex usage up >10x in 6 months to 7M users, +1M in the past ~day; did Codex overtake Claude Code??

OpenAI Codex reached 7M active users on July 13, adding 1M in a single day. That's 10x growth from ~550-700k at the start of 2026 and 2M in March. Anthropic last reported ~2M Claude Code users in February and has been silent since. The post speculates Anthropic shifted focus to Claude Tag, making direct comparisons harder. I'd note the spike coincides with the GPT 5.6 launch and a temporary removal of the 5-hour usage cap — retention remains unproven.

Why it matters: Codex hitting 7M users with 10x growth in 6 months is a real number worth surfacing, and Claude Code's silence since February creates a genuine information gap. The deduction is because this is a paid newsletter digest, not a primary source, and the headline's question mark si...

The headline number is wild: Codex went from 6M to 7M active users in about 24 hours, and from ~600k at the start of 2026 to 7M now. That's a genuine 10x in six months.

But I'd discount the spike a bit. Two things happened at the same time: GPT 5.6 launched on July 9, and on July 12 OpenAI temporarily removed the 5-hour usage cap for Plus, Business, and Pro plans. New model + unlimited access is a classic recipe for a signup surge. Whether those users stick around is a different question, and the post doesn't have retention data.

On the Claude Code side, Anthropic last reported ~2M users in February and has been quiet since. The post's charitable read is that they shifted focus to Claude Tag, a Slackbot product with different usage patterns, making direct comparisons messy. I think that's fair — a CLI tool and a Slackbot aren't measured the same way.

What I'd want to see next: Codex retention after the cap comes back, and any update from Anthropic. Without those, this is a launch-week spike story, not a market-share flip.
