(the “Company”) by the Reporting Persons on October 30, 2020. This Amendment amends and supplements the Schedule 13D filed on May 17, 2007, which has been previously amended on November 18, 2013, October 24, 2014, July 24, 2015, July 28, 2016, July 28, 2017, and July 27, 2018 (the “Schedule 13D”) with respect to the Class A Common Stock of the Company. Except as specified in this Amendment, all previous Items are unchanged. Unless otherwise indicated herein, capitalized terms used but not defined in this Amendment shall have the same meanings herein as are ascribed to such terms in the Schedule 13D.

Item 1. Security and Issuer

The third paragraph of Item 1 is hereby amended and restated to read as follows:

Pursuant to the Amended and Restated Certificate of Incorporation of the Company (the “Restated Charter”), IBG Holdings, as the sole holder of the 100 outstanding shares of the Class B Common Stock, is entitled to the number of votes equal to the number of IBG LLC membership interests held by it at any given time. As of the date of this statement, IBG Holdings holds 325,960,034 IBG LLC membership interests, and, as a result, the Class B Common Stock held by IBG Holdings represents approximately 78.2% of the voting power of the Company. Mr. Thomas Peterffy, through his revocable trust’s ownership of the voting membership interests in IBG Holdings, beneficially owns all of the outstanding shares of the Class B Common Stock, which represent approximately 78.2% of the voting power of the Company.

The following paragraph is hereby added to Item 1:

On October 30, 2020, consistent with the terms of that certain Exchange Agreement entered into by and among the Company, IBG Holdings and IBG LLC and the former members of IBG LLC, previously filed as exhibit 99.3 to this Schedule 13D on May 17, 2007, as amended by that certain amendment previously filed as exhibit 10.1 to the Form 8-K filed on June 12, 2012 and as further amended by that certain amendment filed as an exhibit 10.1 to the Form 10-Q on November 9, 2015, IBG Holdings acquired 11,710,608 shares of Class A Common Stock from the Company in exchange for 11,710,608 membership interests owned by IBG Holdings in IBG LLC and certain tax benefit payments as described in the tax receivable agreement between IBG Holdings and the Company and previously filed as exhibit 10.3 to Form 10-Q on June 15, 2007 (the “TRA”). Such 11,710,608 shares of Class A Common Stock represent approximately 12.9% of the outstanding shares of Class A Common Stock and approximately 2.8% of the voting power of the Company. IBG Holdings, immediately after receipt, distributed such shares in-kind to certain of its members in partial redemption of their IBG Holdings shares.

Item 4. Purpose of Transaction

Item 4 is hereby supplemented by adding the following paragraph:

On October 30, 2020, IBG Holdings acquired 11,710,608 shares of Class A Common Stock in exchange for 11,710,608 membership interests owned by IBG Holdings in IBG LLC and certain tax benefit payments as described in the TRA. IBG Holdings, immediately after receipt, distributed such shares in-kind to certain of its members in partial redemption of their IBG Holdings shares. It is intended that the shares of Class A Common Stock acquired by the redeeming members will be sold in open market transactions  pursuant to Rule 10b5-1 trading plans, more fully described in “Item 6—Contracts, Arrangements, Understandings or Relationships With Respect to the Securities of the Issuer” of this report.

Paragraph (d) of Item 5 is hereby supplemented by adding the following paragraph:

Item 6. Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer.

The first paragraph under subheading “Voting” of Item 6 is hereby amended and restated to read as follows:

Pursuant to the Restated Charter, IBG Holdings, as the sole holder of the 100 outstanding shares of the Class B Common Stock, is entitled to the number of votes equal to the number of IBG LLC membership interests held by it at any given time. Except as otherwise provided by law and the Restated Charter, the Company’s shares of Class A Common Stock and Class B Common Stock vote together as a single class. As of the date of this statement, IBG Holdings holds 325,960,034 IBG LLC membership interests, and, as a result, the Class B Common Stock held by IBG Holdings represents approximately 78.2% of the voting power of the Company. Such percentage voting power is anticipated to decrease over time as a result of the exchange and redemption pursuant to the Exchange Agreement. Mr. Thomas Peterffy, through his revocable trust’s ownership of the voting membership interests in IBG Holdings, beneficially owns all of the outstanding shares of the Class B Common Stock which represent approximately 78.2% of the voting power of the Company.

The following paragraphs are hereby added to Item 6 under the subheading “Voting”:

On October 30, 2020, IBG Holdings acquired 11,710,608 shares of Class A Common Stock for sale for the benefit of certain of its members who elected to redeem a portion of their IBG Holdings membership interests. The shares of Class A Common Stock were acquired in exchange for 11,710,608 membership interests owned by IBG Holdings in IBG LLC and represent approximately 2.8% of the voting power of the Company. These shares of Class A Common Stock were immediately distributed in-kind to certain of IBG Holdings members that elected to redeem shares. The redeeming members included the following executive officers and directors (number of shares of Class A Common Stock in parentheses):

• Thomas Peterffy, Chairman and Founder (10,000,000)

• Thomas A.J. Frank, Executive Vice President (1,000,000)

• Limited liability company for the benefit of Paul J. Brody, Chief Financial Officer (253,332)

Mr. Thomas Peterffy, through his revocable trust’s ownership of the voting membership interests in IBG Holdings, his personal ownership, and shares held through a private foundation established by Mr. Peterffy, holds in the aggregate approximately 80.6% of the total voting power of the Company.

5

The following paragraph is hereby added to Item 6:

Rule 10b5-1 Trading Plans

On October 30, 2020, Mr. Thomas Peterffy adopted a Rule 10b5-1 trading plan (the “TP Plan”) to sell the 10,000,000 (ten million) shares of Class A Common Stock received in partial redemption of his interest in IBG Holdings as described elsewhere in this form. Pursuant to the TP Plan, Mr. Thomas Peterffy will sell up to 20,000 shares of the Company’s Class A Common Stock per trading day at prevailing market prices, subject to the terms of the TP Plan and the limits contained in SEC Rule 144. It is expected the Rule 144 volume limitations will initially cause the TP Plan to sell less than 20,000 shares per day. The transactions will occur until the earlier of the date on which all shares are sold, July 31, 2022 or the TP Plan is terminated in accordance with its terms and applicable law. All transactions under the plans will be disclosed  publicly in accordance with applicable securities laws, rules and regulations through appropriate filings with the SEC, as applicable.

Additionally, on October 30, 2020, a limited liability company indirectly for the benefit of Paul J. Brody, and Thomas A.J. Frank each adopted Rule 10b5-1 trading plans to sell 253,332 and 1,815,458 shares, respectively, of Class A Common Stock received in partial redemption of their respective interests in IBG Holdings. Dr. Frank’s trading plan also includes shares he received in partial redemption of his interest in IBG Holdings in prior years.

Under the terms of these plans, Mr. Brody (through his LLC) and Dr. Frank each intend to sell the shares of Class A Common Stock over time at prevailing market prices, subject to the terms of their respective plans and SEC Rule 144. Neither Mr. Brody nor Dr. Frank will have any control over the timing of the stock sales under their respective plans. The transactions will occur until the earlier of the date on which all shares are sold, July 20, 2021 or the plans are terminated in accordance with its terms and applicable laws. All transactions under the plans will be disclosed  publicly in accordance with applicable securities laws, rules and regulations through appropriate filings with the SEC, as applicable.
