Anthropic Faces Billing Glitch Allegations
Promptmethus · x · 2026-07-11
The post highlights an Anthropic billing anomaly: a South Korean user on a free plan with no API usage was reportedly attempted to be charged $16.6 million, a massive jump from the $1.67 million on the previous day's invoice from the same bill—a roughly 10x increase in a single day. The user initially suspected phishing but confirmed the sender and payment link were from official Anthropic domains; the bank blocked the charge for exceeding the limit. Additionally, audit startup Vaudit reported finding roughly $1.7 million in overcharges across a $34 million AI invoice, primarily tied to Claude Code, noting that contradictory Anthropic billing emails had previously surfaced on GitHub.
