What actually happened
Fetched Sep 20 2026: Wikipedia's Grokipedia page still describes the site as 'Online, but inactive.' Contents have been frozen since late April 2026 (user edits stopped ~Mar 22; Grok autonomous edits stopped late April). Peak article count cited is ~5.6–6.1 million vs English Wikipedia's 7+ million. Grokipedia has not far exceeded Wikipedia and is not currently growing. Deadline end of 2026. Status stays pending.
