Ladies and Gentlemen:

Kismet Acquisition One Corp, a business company incorporated in the British Virgin Islands with limited liability (the “Company”), has filed with the Securities and Exchange Commission a Registration Statement on Form S-1, as amended (File No. 333-239972) (the “Registration Statement”), under the Securities Act of 1933, as amended (the “Act”), covering (i) up to 28,750,000 units of the Company (the “Units”) (including up to 3,750,000 Units subject to the Underwriters’ (as defined below) option to purchase additional Units), with each Unit consisting of one ordinary share of the Company, no par value (“Ordinary Shares,” and the Ordinary Shares underlying the Units, the “Shares”), for an aggregate of up to 28,750,000 Shares (including up to 3,750,000 Shares included in the Units subject to the Underwriters’ option to purchase additional Units) and one-half of one warrant (“Warrant”) each whole Warrant entitling the holder to purchase one Ordinary Share, at a price of $11.50 per share, for an aggregate of up to 14,375,000 Warrants (including up to 1,875,000 Warrants included in the Units subject to the Underwriters’ option to purchase additional Units) to be issued under a Warrant Agreement (the “Warrant Agreement”) to be entered into by the Company and Continental Stock Transfer & Trust Company, as Warrant Agent, pursuant to the terms of an underwriting agreement (the “Underwriting Agreement”) to be executed by the Company, Credit Suisse Securities (USA) LLC and BofA Securities, Inc., as representatives of the underwriters named therein (the “Underwriters”).

We have acted as counsel to the Company in connection with the preparation and filing of the Registration Statement and this opinion is being furnished in accordance with the “Legal Matters” section of the Registration Statement, as it pertains to the portions of New York law set forth below and with the requirements of Item 601(b)(5) of Regulation S-K under the Act.

We have examined originals or certified copies of such corporate records of the Company and other certificates and documents of officials of the Company, public officials, and others, as we have deemed appropriate for purposes of this letter. We have assumed the genuineness of all signatures, the legal capacity of all natural persons, the authenticity of all documents submitted to us as originals, and the conformity to authentic original documents of all copies submitted to us as conformed, certified, or reproduced copies. We have also assumed that (i) upon sale and delivery of the Units, the Shares, and the Warrants, the certificates representing such Units, Shares, and Warrants will conform to the specimens thereof filed as exhibits to the Registration Statement and will have been duly countersigned by the transfer agent and duly registered by the registrar or, if uncertificated, valid book-entry notations for the issuance of the Units, the Shares, and the Warrants in uncertificated form will have been duly made in the register of the Company and (ii) at the time of execution, countersigning, issuance, and delivery of the Warrants, the Warrant Agreement will be a valid and binding obligation of the Warrant Agent, enforceable against the Warrant Agent in accordance with its terms. In addition, in providing the opinions herein, we have relied, with respect to matters related to the Company’s existence, upon the certificates referenced above.

Based upon the foregoing, and subject to the assumptions, exceptions, qualifications, and limitations stated herein, we are of the opinion that:

1. When the Units have been duly executed, issued and delivered by the respective parties thereto and delivered to and paid for by the Underwriters pursuant to the terms of the Underwriting Agreement, the Units will be valid and binding obligations of the Company, enforceable against the Company in accordance with their terms.

2. When the Warrants have been duly executed, issued and delivered by the respective parties thereto and delivered to and paid for by the Underwriters pursuant to the terms of the Underwriting Agreement and the Warrant Agreement, the Warrants will be valid and binding obligations of the Company, enforceable against the Company in accordance with their terms.

The opinions and other matters in this letter are qualified in their entirety and subject to the following:

We hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to the reference to us under the caption “Legal Matters” in the prospectus comprising a part of the Registration Statement. In giving this consent, we do not thereby admit that we are included within the category of persons whose consent is required by Section 7 of the Act and the rules and regulations promulgated thereunder.
