Filed March 23, 2015

File No. 333-194473

Ladies and Gentlemen:

On behalf of our client, Virtu Financial, Inc., a Delaware corporation (the “Company” or “Virtu”), we hereby submit the accompanying Amendment No. 4 to the Registration Statement on Form S-1 of the Company (the “Registration Statement”), marked to indicate changes from the Registration Statement filed with the Commission on March 23, 2015.

The Registration Statement reflects the inclusion of a preliminary price range and the addition of share information and pro forma financial information. It also responds to the comments received from the Staff of the Commission (the “Staff”) in a letter from Suzanne Hayes, dated April 3, 2015 (the “Comment Letter”).  The discussion below is presented in the order of the numbered comments in the Comment Letter.  Certain capitalized terms set forth in this letter are used as defined in the Registration Statement.  For your convenience, except for page references appearing in the headings and Staff comments below, all page references herein correspond to the page in the accompanying Registration Statement.

The Company has asked us to convey the following as its responses to the Staff:

We are a holding company and our principal asset after this offering will be our equity interests in Virtu Finacial…, page 41

1.                                      Please revise the risk factor caption and discussion to clarify that you will only own 23.4% of the economic interests of Virtu Financial.

Response to Comment 1

The Registration Statement has been revised in response to the Staff’s comment. Please see page 43 in the Registration Statement.

Risks Related to this Offering and Our Class A Common Stock, page 47

2.                                      Please add a new risk factor clarifying that only $23.3 million of the net proceeds will be available to Virtu Financial for its use, which may limit its ability to finance growth or engage in other strategic transactions.

Response to Comment 2

The Registration Statement has been revised in response to the Staff’s comment. Please see pages 52-53 in the Registration Statement.
