Interactive Brokers Group reported continued growth across its brokerage business in August, with client equity approaching $1 trillion and the number of client accounts reaching 5.46 million.

The Nasdaq-listed electronic broker recorded 4.28 million daily average revenue trades during the month. That was 23% higher than August 2025, although 3% lower than July.

The monthly decline followed a sharper drop in July, when DARTs fell 16% from June to 4.43 million. Trading activity remained 27% higher than a year earlier in July. Client equity stood at $906.7 billion, while client accounts reached 5.317 million.

Margin Loans Rise to $101.5B

Client assets increased further in August. Ending client equity reached $962.8 billion, up 35% year-on-year and 6% from the previous month. That represented an increase of $56.1 billion from July.

Client margin loan balances also rose to $101.5 billion at the end of August. The figure was 41% higher than a year earlier and 1% above July.

Client credit balances reached $185.6 billion, representing a 27% increase from August 2025 and a 3% rise from the previous month.

The expansion in client numbers continued alongside the growth in assets. Client accounts reached 5.460 million, up 35% year-on-year and 3% from July. The broker added about 143,000 accounts during the month.

Overall, the August figures show that client and asset growth remained strong even as trading activity eased from July. Client equity rose by $56.1 billion during the month, while DARTs declined by 152,000.

DAOL Partnership, August Outage

Beyond its monthly operating metrics, Interactive Brokers has also been expanding its regional presence while dealing with platform issues. Last month, the broker partnered with South Korea’s DAOL Investment & Securities to provide local investors with access to global stocks through DAOL Fi PRO.

It also experienced a temporary access issue during US trading hours recently, affecting a small number of clients in certain APAC data centres. The broker said access was restored within an hour.
