SGN Announces BlockchAIn Has Established a Collaboration with Supermicro for AI Data Center Hardware
Supermicro's AI-optimized compute platforms supports BlockchAIn's U.S. data center development pipeline
SCOTTSDALE, AZ – March 11, 2026 – Signing Day Sports, Inc. (“Signing Day Sports”, “SGN” or the “Company”) (NYSE American: SGN), in connection with the Company’s previously announced proposed business combination with One Blockchain LLC (“BlockchAIn LLC”), today announced that BlockchAIn LLC is collaborating with Super Micro Computer, Inc. (“Supermicro”) (NASDAQ: SMCI), a publicly traded technology company based in San Jose, California that provides total IT solutions for enterprise, cloud, AI, and 5G/Edge infrastructure, including servers, AI systems, storage, networking, software, and support services.
Working together, BlockchAIn LLC intends to deliver an end-to-end AI infrastructure platform by integrating power-secured data center development and operations with standardized, high-density compute hardware designed for AI workloads. With direct access to reliable AI hardware, BlockchAIn LLC expects to bring revenue-producing AI infrastructure online faster and at lower costs than relying on fragmented suppliers, which BlockchAIn LLC believes will drive future operating results. In 2024, BlockchAIn LLC’s operating platform generated approximately $22.9 million in revenue and approximately $5.7 million in net income.
“Leveraging access to Supermicro's hardware portfolio supports our ability to deliver fully integrated AI infrastructure solutions,” said Jerry Tang, Chief Executive Officer of BlockchAIn LLC. “By collaborating with established hardware providers, we can deliver complete solutions tailored to the needs of neocloud and AI-focused customers. We focus on securing power, developing AI-ready facilities, and operating reliable infrastructure.”
Power-First AI Infrastructure Strategy
BlockchAIn LLC’s platform is designed to convert scarce and volatile electricity into predictable, secure AI compute capacity, while remaining hardware-agnostic at the ownership level. The platform supports both flexible and long-duration workloads, allowing AI deployments to scale responsibly within real-world grid and infrastructure constraints as AI adoption expands across industries and demand for dependable AI compute capacity continues to rise.
BlockchAIn LLC believes its power-first approach, combined with vertically integrated infrastructure and direct access to enterprise-grade compute hardware, positions BlockchAIn LLC to serve the growing demand for AI and HPC capacity while maintaining disciplined execution and long-term infrastructure durability.
