Fanatics has confirmed the final roadmap for the complete transition of MLB licensing. Starting with the 2027 season, all flagship products will bear the unified 'Fanatics Heritage' branding. Crucially, the company teased a new 'Proof of Authenticity' chip to be embedded in all high-end hits, which will interlock with grading company data automatically. This technological bridge is expected to virtually eliminate 'slab swapping' in the secondary market.
