By Thomson Reuters Jul 21, 2026 | 4:20 PM

July 21 (Reuters) – Trading platform Interactive Brokers reported a 35% rise in second-quarter profit on Tuesday, bolstered by elevated trading ​activity due to a sharp rally in ‌U.S. equity markets during the period.

The S&P 500 and Nasdaq posted strong gains during the April-to-June quarter as investors looked past geopolitical uncertainty and remained optimistic ‌about ​AI-driven earnings growth.

Here are some ⁠more details:

• The broker’s ⁠net interest income rose 23% to $1.06 billion in the second quarter, as a result of higher average customer margin loans and ​credit balances.

• Commission revenue – the amount the brokerage earns when clients execute trades – increased 30% ⁠in the reported quarter ⁠compared to the prior year supported ​by higher customer trading volumes across major asset ​classes, including equities, futures and options.

• Daily ‌average revenue trades, or DARTs, which signify the average trades per day generating commissions or fees, rose 36% in the quarter to 4.82 ⁠million trades.

• The Greenwich, Connecticut-based company reported net income available for common stockholders of $312 million, or 69 ⁠cents per ‌share, for the three months ended ⁠June 30, compared with $224 million, or ​51 ‌cents per share, for the ​same period, ⁠in the prior year.

• Peer brokerage firm Charles Schwab also posted a record second-quarter profit, boosted by robust trading activity and increased asset management fees.
