Interactive Brokers Group, Inc. (IBKR): Shares Outstanding

Annual figures by period end, from SEC filings.

Stock splits: 4-for-1, first reflected in a filing dated 2025-08-06. Figures are as filed: per-share figures and share counts last reported before a split are on the old share basis, so changes and growth rates across a split are not shown. Splits are read from the filings' own restatements, so a share conversion in a merger or reorganization shows up the same way.

Older than the company's other figures. The latest Shares Outstanding is for the year ended 2015-12-31, while the company's latest annual report covers the year ended 2025-12-31. Its later filings do not report this line under the concept TickerFacts maps.
