Signing Day Sports Files Public S-4 Registration as It Moves Toward BlockchAIn Merger

Signing Day Sports, Inc. has publicly filed a Form S-4 Registration Statement with the U.S. Securities and Exchange Commission, marking a major step toward its planned merger with One Blockchain LLC. The filing was submitted by BlockchAIn Digital Infrastructure, Inc., a newly formed Delaware entity created to complete the transaction. This follows multiple confidential submissions earlier in the year.

Details of the Agreement and Planned NYSE American Listing

The business combination agreement, originally announced in May and amended in November, outlines the formation of BlockchAIn as the public successor company. Upon completion, BlockchAIn intends to list its common shares on the NYSE American under the ticker “AIB.” The Registration Statement provides disclosures about the merger structure and future operations.

CEO Highlights Strategic Alignment and Execution

CEO Daniel Nelson emphasized that the filing represents a significant milestone and reflects sustained preparation from both organizations. According to Nelson, the partnership has been driven by aligned long-term goals and coordinated execution designed to keep the process on schedule.

Combined Company Aims to Expand Technological and Financial Capabilities

Nelson stated that integrating Signing Day Sports’ recruitment technology with One Blockchain’s digital infrastructure and high-performance computing resources will create a business with greater financial flexibility and broader technical capacity. This foundation is expected to support expansion initiatives that were previously out of reach.

Merger Expected to Accelerate Innovation and Growth

The company anticipates that the transaction will enable faster development of new tools for student-athletes and coaches, open pathways to new partnerships, and strengthen its market position. Access to public markets is expected to provide additional operational capacity and long-term value creation opportunities.
