Interactive Brokers shares are moving higher today as investors react to the company’s latest monthly electronic brokerage statistics, which highlighted continued strength in client activity and account growth. The March 2026 snapshot showed total client DARTs a little over 4.3 million, roughly +25% year over year, keeping the firm’s trading-activity trend constructive even with a small month-over-month dip from February.

The monthly metrics indicated total client accounts at roughly 4.75 million in March 2026, up about 31% from a year earlier, alongside client equity around $814 billion. The report also showed client credits and margin loans remaining elevated versus last year, pointing to a large balance base that can support recurring net interest income and financing-related revenue streams.

Monthly operating prints are closely watched for brokerages because they provide a near-real-time read on customer engagement and monetization ahead of quarterly earnings. With IBKR’s next earnings release scheduled for April 21, 2026, the March activity update is being treated as a positive signal for Q1 results and for the durability of IBKR’s growth in active accounts.
