FinanceYF5 · x · 2026-07-14

A Korean Claude user received an astronomical **$16.62 million** bill from Anthropic, despite claiming to use the free tier without any API activity. - **Skyrocketing Amount**: An initial email cited a failed charge of $1.66 million, which skyrocketed nearly 10x to $16.62 million the next day. - **Charge Anomalies**: The emails were sent via Stripe from official domains. The user hadn't linked a card, but bank records showed two failed attempts to charge their card on July 8 for exceeding limits. - **Official Response**: All charges failed, and no actual money was transferred. Anthropic stated it couldn't verify individual account details but hasn't confirmed if this was a system glitch.
