Interactive Brokers’ $182.4B idle cash jump lifts client-cash earnings ahead of Anthropic IPO
Interactive Brokers ended June with $182.4 billion in uninvested client cash, up 27% from a year earlier, and that pile climbed to $185.6 billion by late August. IBKR earns on client cash, and Q2 earnings rose 23% to $1.06 billion as customer margin loans jumped 67%. Commission revenue hit a record $673 million, and daily average revenue trades rose 23%, potentially helped again by an Anthropic IPO.
