Atlanta United's valuation rose 2.6% to $975M, lagging the MLS median growth of 5.1% per Forbes 2025 data. Arthur Blank's franchise remains in the middle tier of league valuations, behind LAFC ($1.05B) and Seattle ($1.02B). The modest 2.6% gain reflects softer stadium attendance recovery and flat regional corporate sponsorship versus peers benefiting from Apple TV's $2.5B media rights expansion. Atlanta's growth trails comparable markets because Mercedes-Benz Stadium hosts competing events and regional sports equity concentration limits incremental partnership upside. MLS valuations inflated 47% across the league since 2022, driven by media deals and expansion franchise premiums, but mature franchises like Atlanta face maturation headwinds.
