**EXPLANATORY NOTE**

This registration statement is being filed with the Securities and Exchange Commission pursuant to General Instruction K of Form S-4 and Rule 462(b) of the Securities Act of 1933, as amended, for the sole purpose of registering an additional 7,000,000 shares of common stock, $0.001 par value per share ("Blackboxstocks common stock"), of Blackboxstocks Inc. ("Blackboxstocks") for issuance in connection with the merger of REalloys Inc. ("REalloys") with and into RABLBX Merger Sub, Inc., a wholly owned subsidiary of the registrant ("Merger Sub"), with REalloys continuing as the surviving corporation. Blackboxstocks has previously registered 54,772,915 shares of Blackboxstocks common stock by means of a currently effective registration statement on Form S-4 (Registration No. 333-286507). The number of shares originally registered represented the maximum number of shares of Blackboxstocks common stock estimated to be issuable in connection with the merger, based on the number of shares of common stock outstanding, as of January 14, 2026, and the exchange of shares of REalloys common stock for Blackboxstocks common stock pursuant to an assumed exchange ratio of 0.3694. The number of shares of Blackboxstocks common stock issuable upon the completion of the merger is now estimated to be higher than originally anticipated due to a higher exchange ratio calculated pursuant to the terms of that certain Agreement and Plan of Merger, dated as of March 10, 2025, as amended. Thus, Blackboxstocks is registering an additional 7,000,000 shares of Blackboxstocks common stock.

**INCORPORATION OF DOCUMENTS BY REFERENCE**

Blackboxstocks, Inc.<br> 5430 LBJ Freeway, Suite 1485<br> Dallas, Texas 75240

Ladies and Gentlemen:

We have acted as legal counsel to Blackboxstocks, Inc., a Nevada corporation (the "<u>Company</u>"), in connection with (i) the Registration Statement on Form S-4 (File No. 333-286507) (the "<u>Initial Registration Statement</u>"), filed by the Company with the Securities and Exchange Commission (the "<u>Commission</u>") under the Securities Act of 1933, as amended (the "<u>Securities Act</u>"), relating to the registration and issuance of up to 54,772,915 shares of its common stock, par value $0.001 per share ("<u>Common Stock</u>"), and 5,000 shares of Series C Convertible Preferred Stock, par value $0.001 per share, stated value $3,000 per share ("<u>Series C Preferred Stock</u>, and together with the Common Stock, the "<u>Shares</u>"), and (ii) the related Registration Statement on Form S-4 (the "<u>462(b) Registration Statement</u>," and together with the Initial Registration Statement, the "<u>Registration Statements</u>") filed by the Company with the Commission on the date hereof pursuant to Rule 462(b) promulgated under the Securities Act, relating to the registration and issuance of up to an additional 7,000,000 shares of Common Stock (the "<u>Additional Shares</u>"). The 462(b) Registration Statement incorporates by reference the Initial Registration Statement that was declared effective by the Commission on January 16, 2026. The Additional Shares are proposed to be offered upon consummation of the merger (the "<u>Merger</u>") of RABLBX Merger Sub, Inc., a Nevada corporation and wholly owned subsidiary of the Company ("<u>Merger Sub</u>"), with and into REalloys Inc., a Nevada corporation ("<u>REalloys</u>"), pursuant to that certain Agreement and Plan of Merger, dated March 10, 2025, as amended by the First Amendment to Agreement and Plan of Merger dated July 1, 2025, the Second Amendment to Agreement and Plan of Merger dated August 22, 2025, and the Third Amendment to Agreement and Plan of Merger dated December 10, 2025, by and among the Company, Merger Sub and REalloys (the "<u>Merger Agreement</u>").

In connection with this opinion, we have examined originals or copies, certified or otherwise identified to our satisfaction, of (i) the Registration Statements, (ii) the Merger Agreement; (iv) the Articles of Incorporation of the Company, as currently in effect; (v) the Amended and Restated Bylaws of the Company, as currently in effect and (vi) certain resolutions of the Board of Directors of the Company (the "<u>Board</u>") relating to the Merger Agreement. We have also examined originals or copies, certified or otherwise identified to our satisfaction, of such records of the Company and such agreements, certificates of public officials, certificates of officers or other representatives of the Company and others, and such other documents, certificates and records as we have deemed necessary or appropriate as a basis for the opinion set forth herein.

In our examination, we have assumed and have not verified (i) the legal capacity of all natural persons; (ii) the genuineness of all signatures (other than persons signing on behalf of the Company); (iii) the authenticity of all documents, certificates and instruments submitted to us as originals; (iv) the conformity with the originals of all documents supplied to us as copies; (v) the accuracy and completeness of all corporate records and documents made available to us by the Company; and (vi) that the foregoing documents, in the form submitted to us for our review, have not been altered or amended in any respect material to our opinion stated herein. We have relied as to factual matters upon certificates from officers of the Company and certificates and other documents from public officials and government agencies and departments and we have assumed the accuracy and authenticity of such certificates and documents. We have also assumed that, at or prior to the time of the issuance and delivery of any Additional Shares, that there will not have occurred, other than as provided for in the Merger Agreement, any change in law, change in the Additional Shares, the Merger Agreement or the Company's Articles of Incorporation, or further action by the Company's Board, in each case affecting the validity of the issuance of the Additional Shares.

Blackboxstocks, Inc.<br> February 24, 2026

In connection with the opinions expressed below, we have assumed that, at and prior to the time of the issuance and delivery of the Additional Shares by the Company pursuant to the Registration Statements, (i) all Additional Shares will be issued and sold in compliance with applicable federal and state securities laws and in the manner stated in the Registration Statements and the Merger Agreement, (ii) with respect to the Additional Shares, there will be sufficient shares of Common Stock authorized under the Company's Articles of Incorporation, as currently in effect and as amended pursuant to the Merger Agreement, and not otherwise reserved for issuance, (iii) the Registration Statements will have been declared effective and no stop order suspending the effectiveness of the Registration Statements has been issued and no proceedings with respect thereto have been commenced or threatened, and (iv) the transactions contemplated by the Merger Agreement and the Registration Statements will have been consummated in accordance with the terms of the documents pertaining thereto, without any waiver or breach of any material terms or provisions thereof, and that such transactions will be effective under applicable law.

Based upon and subject to the foregoing, it is our opinion that, when the Additional Shares are issued and delivered by the Company in accordance with the Merger Agreement, the Additional Shares will be validly issued, fully paid and non-assessable.

Our opinion is limited to the federal laws of the United States and Chapter 78 of the Nevada Revised Statutes. We express no opinions as to the laws of any other jurisdiction. No opinion is expressed herein with respect to the qualification of the Additional Shares under the securities or blue sky laws of any state or any foreign jurisdiction. The opinion expressed herein is given as of this date, and we do not undertake to supplement this opinion with respect to any events or changes occurring subsequent to the date of this letter. The opinion expressed in this letter is provided as a legal opinion only and not as a guarantee or warranty of the matters discussed herein, and such opinion is strictly limited to the matters stated herein, and no other opinion may be implied therefrom.

We hereby consent to the filing of this opinion as an exhibit to the 424(b) Registration Statement, and we further consent to the use of our name under the caption "Legal Matters" in the Initial Registration Statement. In giving these consents, we do not thereby admit that we are within the category of persons whose consent is required under Section 7 of the Securities Act or the or the rules and regulations of the Commission promulgated thereunder.

Blackboxstocks, Inc.

5430 LBJ Freeway, Suite 1485

Dallas, Texas 75240

Dear: Ladies and Gentlemen:

We have acted as counsel to Blackboxstocks, Inc., a Nevada corporation ("<u>BLBX</u>"), in connection with the transactions described in the registration statement (the "<u>Merger</u>") on Form S-4 MEF filed on the date hereof, together with and incorporated by reference the registration statement on Form S-4 with Registration Number 333-286507 (the "<u>Registration Statement</u>") of which this exhibit is a part. All section references, unless otherwise indicated, are to the United States Internal Revenue Code of 1986, as amended (the "<u>Code</u>"). Capitalized terms not defined herein have the meanings set forth in the Registration Statement.

In preparing this opinion, we have examined and relied upon the Registration Statement, including the Prospectus included therein, the Agreement and Plan of Merger dated as of March 10, 2025, as subsequently amended (the "<u>Merger Agreement</u>") by and among BLBX, RABLBX Merger Sub, Inc., a Nevada corporation ("<u>Merger Sub</u>"), and REalloys, Inc., a Nevada corporation ("<u>REalloys</u>"), and certain shareholders of REalloys stock, the representation letters of BLBX and REalloys delivered to us for purposes of rendering our opinion stated herein (the "<u>Representation Letters</u>") and such other documents as we have deemed necessary or appropriate in order to enable us to render this opinion. In our examination of documents, we have assumed the authenticity of original documents, the accuracy of copies, the genuineness of signatures, and the legal capacity of signatories. We have also assumed that the transactions described in the Registration Statement will be consummated in accordance with the description in the Registration Statement.

In rendering this opinion, we have assumed without investigation or verification that the facts and statements set forth in the Registration Statement and the Merger Agreement are true, correct and complete in all material respects; that the Merger will be completed in accordance with the Registration Statement and the Merger Agreement (and no transaction or condition described therein and affecting this opinion will be waived by any party); the factual statements and representations made in the respective Representation Letters are true, complete and correct as of the date hereof and will remain true, complete, and correct at all times; that any representation in any of the documents referred to herein that is made "to the best of the knowledge and belief" (or similar qualification) of any person or party is true, correct, and complete without such qualification; that, as to all matters for which a person or entity has represented that such person or entity is not a party to, does not have, or is not aware of, any plan, intention, understanding, or agreement, there is no such plan, intention, understanding, or agreement; and that BLBX and REalloys and their respective subsidiaries will treat the Merger for United States federal income tax purposes in a manner consistent with statements in the Registration Statement. Any inaccuracy in, or breach of, any of the aforementioned statements, representations or assumptions could adversely affect our opinion.

![](ex8-1_001.jpg)

February 24, 2026

Our opinion is based on existing provisions of the Code, Treasury Regulations, judicial decisions, and rulings and other pronouncements of the Internal Revenue Service as in effect on the date of this opinion, all of which are subject to change (possibly with retroactive effect) or reinterpretation. No assurances can be given that a change in the law on which our opinion is based or the interpretation thereof will not occur or that such change will not affect the opinion expressed herein. We undertake no responsibility to advise of any such developments in the law.

Based on our examination of the foregoing items and subject to the limitations, qualifications, assumptions and caveats set forth herein, we confirm that the statements in the Registration Statement under the heading "Certain Material U.S. Federal Income Tax Consequences of the Merger – Qualification of the Merger as a Reorganization," "Certain Material U.S. Federal Income Tax Consequences of the Merger – Material U.S. Federal Income Tax Treatment of the Reverse Stock Split," and "Certain Material U.S. Federal Income Tax Consequences of the Receipt of Contingent Value Rights," subject to the limitations and qualifications described therein, insofar as they relate to matters of United States federal income tax law, constitute our opinion of the material United States federal income tax consequences of the transactions described therein.

No opinion is expressed as to any matter not discussed herein.

We hereby consent to the use of our name under the heading "Legal Matters" in the Registration Statement and to the filing of this opinion as an exhibit to the Registration Statement.

Sincerely, <br> Winstead PC

Pursuant to Rule 416 under the Securities Act of 1933, as amended (the "Securities Act"), there are also being registered such additional shares of common stock that may be issued because of events such as recapitalizations, stock dividends, stock splits, and similar transactions. The Maximum Aggregate Offering Price is estimated solely for the purposes of calculation of the registration fee in accordance with Rule 457(f) of the Securities Act of 1933, as amended (the "Securities Act"). REalloys is a private company and no market exists for its equity securities. Additionally, REalloys has accumulated a capital deficit; therefore, pursuant to Rule 457(f)(2) under the Securities Act, the proposed offering price is one-third of the aggregate par value of REalloys' capital stock being exchanged in the proposed Merger, which is calculated as one-third of the product of the par value of $0.0001 per share multiplied by 125,383,766 shares of REalloys common stock.
