Interactive Brokers Group, Inc. is expected to file its next quarterly report (Form 10-Q), for the period ending about Sept. 30, 2026, between Nov. 5, 2026 and Nov. 9, 2026, based on its last 8 10-Q filings. The SEC deadline for a large accelerated filer is Nov. 9, 2026.
How the next-report window is calculated
Interactive Brokers Group, Inc.'s most recent periodic report on file is a Form 10-Q for the period ended June 30, 2026, filed Aug. 6, 2026. Its fiscal year ends around Dec. 31, so the next period should close about Sept. 30, 2026, and that report is a Form 10-Q.
SEC rules give a large accelerated filer 40 days after period end to file a 10-Q, which lands on Nov. 9, 2026 after moving off weekends and federal holidays. Over its last 8 10-Qs, Interactive Brokers Group, Inc. filed between 36 and 38 days after period end (median 37 days), which gives the expected window above. Period ends are estimated from the company's own calendar and may shift by a few days in 52/53-week fiscal years.
