To the addressee set forth above:

We have acted as special counsel to FuboTV Inc., a Delaware corporation (the “Company”), in connection with the resale from time to time by the selling stockholders (the “Selling Stockholders”) named in the Prospectus Supplement (as defined below) of up to 947,910,220 shares (the “Shares”) of the Company’s Class A common stock, par value $0.0001 per share (the “Class A Common Stock”). The resale of the Shares is being registered pursuant to a registration statement on Form S-3 under the Securities Act of 1933, as amended (the “Act”), filed with the Securities and Exchange Commission (the “Commission”) on January 23, 2026 (Registration No. 333-292921) (as amended, the “Registration Statement”), a base prospectus dated January 23, 2026 included in the Registration Statement at the time it originally became effective (the “Base Prospectus”), and a prospectus supplement dated January 23, 2026 filed with the Commission pursuant to Rule 424(b) under the Act (the “Prospectus Supplement,” and together with the Base Prospectus, the “Prospectus”).

This opinion is being furnished in connection with the requirements of Item 601(b)(5) of Regulation S-K under the Act, and no opinion is expressed herein as to any matter pertaining to the contents of the Registration Statement or the Prospectus, other than as expressly stated herein with respect to the issuance of the Shares.

As such counsel, we have examined such matters of fact and questions of law as we have considered appropriate for purposes of this letter. With your consent, we have relied upon certificates and other assurances of officers of the Company, the Selling Stockholders and others as to factual matters without having independently verified such factual matters. We are opining herein as to the General Corporation Law of the State of Delaware (the “DGCL”), and we express no opinion with respect to any other laws.

Subject to the foregoing and the other matters set forth herein, it is our opinion that the Shares have been duly authorized by all necessary corporate action of the Company and reserved for issuance upon the exercise, conversion or exchange of other securities of the Company or any of its subsidiaries (including shares of Class B common stock, par value $0.0001 per share, of the Company and units in Fubo Operations LLC, a Delaware limited liability company) owned by the Selling Stockholders, and, assuming issuance of the Shares upon the exercise, conversion or exchange of other securities of the Company on the date hereof, would be validly issued, fully paid and nonassessable.

In rendering our opinion, we have assumed that the Company will comply with all applicable notice requirements regarding uncertificated shares provided in the DGCL.

This opinion is for your benefit in connection with the Prospectus Supplement and may be relied upon by you and by persons entitled to rely upon it pursuant to the applicable provisions of the Act. We consent to your filing this opinion as an exhibit to the Company’s Current Report on Form 8-K filed with the Commission on January 23, 2026 and to the reference to our firm contained in the Prospectus Supplement under the heading “Legal Matters.” In giving such consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Act or the rules and regulations of the Commission thereunder.
