Theo says a $200 Claude sub bought him $9,000 of Opus a month

Theo says he ran three Claude accounts down to 0% since Opus 5.5 shipped, and that a $200 Claude Code subscription yields roughly $9,000 of Opus usage a month. He puts the three accounts' usage at $2,086, $2,442 and $2,182, an average of about $2,200 a week.
