Interactive Brokers Group, Inc.: what insiders have been doing
Interactive Brokers Group, Inc., founded in 1994, is a Finance & Banking company based in Greenwich, United States. Its directors and officers file their transactions with SEC (Form 4). In the past year (18 October 2025 to 18 October 2026), 38 filings came from 11 insiders.
The record shows 7 purchases on the open market worth €33k, made by 2 insiders, against 6 sales worth €14.5M by 2 insiders. No amount is published for 1 filing, which the totals therefore leave out. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. The buyers include 2 senior executives. The largest single trade was a sale of €6.6M by Nemser Earl H, published on 26 January 2026.
Compared with its exchange (5,812 companies, median 19 filings), a count of 38 filings is above the norm. Looking back to 2016, when coverage begins, insiders filed 8 purchases and 339 sales. For the fiscal year to 31 December 2025, the annual 10-K puts net income at 4.36 bn USD.
The most recent open-market purchase was published on 5 October 2026, 13 days ago. The median gap between a trade and its publication by SEC (Form 4) is 7 days. The legal deadline for a Form 4 is two business days after the transaction.
For comparison within the same sector, see the insider buying recorded at First Guaranty Bancshares, Inc. and Avidia Bancorp, Inc. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.

About Interactive Brokers Group, Inc.
Interactive Brokers Group, Inc. (ticker: IBKR) is a leading global electronic brokerage platform listed on the U.S. Nasdaq market in the United States. Founded by Thomas Peterffy, the firm began its broker-dealer business in 1977 and has since built a highly scalable model centered on automated execution, direct market access, and competitive pricing. Its operating headquarters are in Greenwich, Connecticut, with additional market-related functions tied to Chicago, Illinois. The company’s long-standing mission is technology-led: to create liquidity on better terms by competing on price, speed, order size, product breadth, and advanced trading tools.
IBKR’s core business is brokerage, clearing, and settlement for a broad client base that includes active retail investors, professional traders, hedge funds, mutual funds, registered investment advisors, proprietary trading groups, introducing brokers, and other institutions. The platform offers access to a wide range of electronically traded products, including stocks, options, futures, currencies, bonds, funds, precious metals, and crypto-related products, supported by a robust automated infrastructure. This makes Interactive Brokers particularly relevant to sophisticated investors seeking multi-asset, multi-currency access with institutional-grade execution quality.

From a competitive standpoint, Interactive Brokers stands out from traditional retail brokers through its global reach, low-cost structure, deep market access, and professional-grade technology. The company states that it operates across more than 170 market destinations worldwide, which enhances its appeal to international clients who value breadth of product, execution efficiency, and the ability to trade across regions from a single platform. In a brokerage industry where technology, pricing, and global market coverage are key differentiators, IBKR has established a strong position as a scalable, automation-driven platform with institutional characteristics.
Recent developments reinforce this strategic positioning. In May 2026, the company announced a unified interface for prediction markets, enabling access to Kalshi, CME Group, and ForecastEx from one platform, alongside its established offerings in equities, options, forex, futures, crypto, and bonds. During 2025, IBKR also rolled out and upgraded IBKR Desktop and introduced new investment-discovery tools, while continuing to expand access to additional foreign exchanges. These initiatives suggest a continued focus on product innovation, international expansion, and platform depth. For investors following U.S.-listed financial technology and brokerage names, Interactive Brokers remains a notable Nasdaq-listed player in the United States with a strong global footprint and a technology-first operating model.
