Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) This amount represents the $42.00 price at which the issuer's shares of Class A common stock (the "Class A Common Stock") were sold in a public offering of the Class A Common Stock (the "Public Offering"), less the underwriters' discount of $1.26 per share.
(2) This amount includes 42,508 unvested restricted stock units in respect of the issuer's Class A Common Stock. Subject to the reporting person's continued employment through each vesting date, these restricted stock units are scheduled to vest as follows: (i) 19,641 restricted stock units will vest on January 1, 2020 and (ii) 22,867 restricted stock units will vest on January 1, 2021.
(3) Shares of Class D common stock of the issuer ("Class D Common Stock") have ten votes per share but no economic rights (including rights to dividends or, other than their par value, any distribution upon liquidation) and are issued in an equal amount to the number of non-voting common units of Tradeweb Markets LLC, a subsidiary of the issuer ("LLC Units"), held. Shares of Class D Common Stock are exchangeable for shares of the issuer's Class C common stock ("Class C Common Stock"), which have one vote per share but no economic rights (other than their par value upon liquidation), on a one-for-one basis at the discretion of the holder. These exchange rights do not expire.
(4) The reporting person sold to the issuer the number of LLC Units set forth above at a price per LLC Unit of $40.74, which represents the $42.00 price at which the issuer's Class A Common Stock was sold in the Public Offering, less the underwriters' discount of $1.26 per share. The corresponding number of shares of Class D Common Stock along with the exchange rights thereunder were canceled in their entirety in connection with the sale of the LLC Units.
(5) Pursuant to the terms of the limited liability company agreement for Tradeweb Markets LLC, LLC Units may be exchanged for shares of Class A Common Stock or Class B common stock of the issuer, in each case, on a one-for-one basis at the discretion of the holder. Upon such an exchange, a corresponding number of shares of Class D Common Stock (or shares of Class C Common Stock, in the event the reporting person exchanged their shares of Class D Common Stock as described in footnote 3 to this Form 4) will be canceled. These exchange rights do not expire.
