Dear Sirs

Mega Matrix Inc. (the Company)

We have acted as Cayman Islands counsel to the Company in connection with the Company’s registration statement on Form S-8, including all amendments or supplements thereto (the Registration Statement), as filed with the United States Securities and Exchange Commission (the Commission) under the United States Securities Act of 1933, as amended to date (the Act). The Registration Statement relates to the Company’s amended and restated 2021 equity incentive plan (the 2021 Equity Incentive Plan), originally filed by Mega Matrix Corp., a Delaware company (MPU DE), which covered a total of 1,580,000 shares of common stock of MPU DE and was assumed by the Company after a redomicile merger consummated on 8 October 2024. After the merger, each issued and outstanding share of MPU DE’s common stock outstanding prior to 8 October 2024 has been converted to the right to receive one class A ordinary share, par value of $0.001 (Class A Ordinary Share), of the Company. In addition, each outstanding option and warrant exercisable into common stock of MPU DE has been assumed by the Company under the same terms and conditions. We are furnishing this opinion as Exhibit 5.1 to the Registration Statement.

Unless a contrary intention appears, all capitalised terms used in this opinion have the respective meanings set forth in the Documents (as defined below). The headings herein are for convenience only and do not affect the construction of this opinion.

(j) the Company shall have sufficient number of unissued shares in its authorised share capital at the time of issuance of the shares (the ESOP Shares) under the 2021 Equity Incentive Plan, which plan covers a total of 1,580,000 Class A Ordinary Shares, in order for it to issue the ESOP Shares without needing to first increase its authorised share capital;

3 Opinions

On the basis of the examinations and assumptions referred to above and subject to the limitations and qualifications set forth in paragraph 4 below, we are of the opinion that:

Corporate status

(a) The Company has been duly incorporated as an exempted company with limited liability and is validly existing and in good standing with the Registrar under the laws of the Cayman Islands.

Authorised Share capital

(b) The authorised share capital of the Company is USD120,000 divided into (i) 100,000,000 class A ordinary shares of par value USD0.001 each, (ii) 10,000,000 class B ordinary shares of par value USD0.001 each and (iii) 10,000,000 Preferred Shares of par value USD0.001 each.

Valid Issuance of Shares

(c) The ESOP Shares to be issued under the 2021 Equity Incentive Plan have been duly authorised by all necessary corporate actions of the Company under the Memorandum and Articles and, upon the issuance and delivery of the ESOP Shares in accordance with the Memorandum and Articles, the Resolutions and the terms of the 2021 Equity Incentive Plan and once consideration of not less than the par value is fully paid per ESOP Share in accordance with the 2021 Equity Incentive Plan to the Company, the ESOP Shares will be validly issued, fully paid and non-assessable. Once the register of members of the Company has been updated to reflect the issuance of the ESOP Shares, the shareholders recorded in the register of members of the Company will be deemed to have legal title to the shares of the Company set out against their respective name.

4 Limitations and Qualifications

4.1 We offer no opinion:

(a) as to any laws other than the laws of the Cayman Islands, and we have not, for the purposes of this opinion, made any investigation of the laws of any other jurisdiction, and we express no opinion as to the meaning, validity, or effect of references in the 2021 Equity Incentive Plan to statutes, rules, regulations, codes or judicial authority of any jurisdiction other than the Cayman Islands; or

(b) except to the extent that this opinion expressly provides otherwise, as to the commercial terms of, or the validity, enforceability or effect of the Form S-8, the accuracy of representations, the fulfilment of warranties or conditions, the occurrence of events of default or terminating events or the existence of any conflicts or inconsistencies among the Registration Statement and any other agreements into which the Company may have entered or any other documents.

4.2 Under the Companies Act (Revised) (Companies Act) of the Cayman Islands annual returns in respect of the Company must be filed with the Registrar, together with payment of annual filing fees. A failure to file annual returns and pay annual filing fees may result in the Company being struck off the Register of Companies, following which its assets will vest in the Financial Secretary of the Cayman Islands and will be subject to disposition or retention for the benefit of the public of the Cayman Islands.

4.3 In good standing means only that as of the date of this opinion the Company is up-to-date with the filing of its annual returns and payment of annual fees with the Registrar. We have made no enquiries into the Company’s good standing with respect to any filings or payment of fees, or both, that it may be required to make under the laws of the Cayman Islands other than the Companies Act.

6 Reliance

We hereby consent to the filing of this opinion as an exhibit to the Form S-8.

Yours faithfully
