Interactive Brokers Group Reports Brokerage Metrics and Other Financial Information for December 2025, includes Reg.-NMS Execution Statistics

Key Terms

daily average revenue trades financial

Daily average revenue trades represent the typical amount of money a financial firm earns each day from the buying and selling of securities. It is calculated by adding up the total revenue generated from trades over a period and dividing it by the number of days in that period, giving a smooth, average figure. This metric helps investors understand how active and profitable a trading business is on a consistent basis.

mark to market financial

Mark to market is an accounting practice that records the value of an asset or liability at its current market price instead of its original purchase cost. For investors, it means a company's reported earnings, balance sheet and capital ratios change as market prices move—like updating a price tag each day—so reported profits and risk can fluctuate quickly with market swings.

reg.-nms regulatory

Reg.-NMS (Regulation NMS) is a set of market rules that govern how U.S. stock trades are routed and executed, designed to make sure investors get the best available prices across different trading venues. Think of it like traffic rules for markets that require brokers and exchanges to check nearby lanes for better deals before completing a trade; it matters because those rules affect how quickly orders fill, the price you receive, and overall trading costs.

vwap financial

VWAP, or Volume-Weighted Average Price, is a way to find the average price of a stock throughout the trading day, giving more importance to times when more shares are traded. It helps traders see the typical price and decide whether a stock is expensive or cheap compared to its average, similar to finding the average speed during a trip by giving more weight to times when you traveled faster or slower.

basis points financial

Basis points are a way to measure small changes in interest rates or percentages, where one basis point equals 0.01%. For example, if a loan's interest rate increases by 50 basis points, it's gone up by 0.50%. They help people understand tiny differences in rates that can add up over time, making financial comparisons clearer.

fdic insured regulatory

A U.S. government insurance program that protects money held in eligible bank and savings accounts up to a set limit if the bank fails. It matters to investors because it acts like a safety net for cash — reducing the risk of losing deposits and helping decide where to park short‑term funds — but it does not cover stocks, bonds, mutual funds, or cryptocurrencies.

________________

Note 1: Daily Average Revenue Trades (DARTs) – customer orders divided by the number of trading days in the period.

Note 2: FDIC insured client bank deposit sweep program balances with participating banks. These deposits are not reported in the Company’s statement of financial condition.

Note 3: Commissionable Order – a customer order that generates commissions.

Note 4: Mark to market gains and losses on investments in U.S. government securities and associated hedges are included in Other Income. In the general course of business, we hold these investments to maturity. As a result, accumulated mark to market gains or losses should converge to zero at maturity. Accounting conventions require broker-dealers, unlike banks, to mark all investments to market.

Note 5: In connection with our currency diversification strategy, we have determined to base our net worth in GLOBALs, a basket of 10 major currencies in which we hold our equity. The total effect of the currency diversification strategy is reported in Comprehensive Income and the components are reported in (1) Other Income and (2) Other Comprehensive Income (“OCI”) on the balance sheet. The effect of the GLOBAL on our comprehensive income can be estimated by multiplying the total equity for the period by the change in the U.S. dollar value of the GLOBAL during the same period.

Note 6: Trade money is the total amount of money clients spent or received, including all commissions and fees.

Note 7: Consistent with the clients’ trading activity, the computed VWAP benchmark includes extended trading hours.
