Explanation of Responses:

1. The reporting person was granted two awards of restricted stock units under the terms of the Amended and Restated Tradeweb Markets Inc. PRSU Plan consisting of (i) a grant of 32,140 restricted stock units which will vest on January 1, 2020, and (ii) a grant of 42,218 restricted stock units which will vest on January 1, 2021, each subject to the reporting person's continued employment on such date. Each grant of restricted stock units represents a contingent right to receive one share of Class A common stock of the issuer ("Class A Common Stock").

2. 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.

3. 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 2 to this Form 3) will be canceled. These exchange rights do not expire.

4. The reporting person owns an option to purchase 407,609 shares of Class A Common Stock, which is vested as to 326,087 of the shares subject thereto as of the date hereof. The remainder of the option will vest on January 1, 2020, subject to the reporting person's continued employment on such date.
