Anthropic's threat report says Moonshot relayed ~300,000 Kimi requests to Claude through 5,380 accounts.

The September 2026 report alleges Moonshot forwarded Kimi user requests to Claude, mostly Opus, through accounts registered largely in Singapore and Japan, returning Claude's answers as Kimi's and retaining chain-of-thought traces. The detail r/ClaudeAI seized on at 951 upvotes is the reversal: one engineer building an internal system for a major PRC state-owned enterprise pasted internal code and live credentials from multiple Chinese technology companies into Kimi, with no way to know it was being forwarded to a US lab. A skeptical minority in the thread calls it unproven IPO-timed marketing, and since the report is Anthropic's own telemetry with no independent verification, hold both.
