The San Francisco 49ers jumped to $8.6B valuation in 2025, a $2.1B lift from $6.5B two years prior. Per Matchex data, this 32.3% growth outpaces the median NFL franchise appreciation of 18% over the same period, positioning York's ownership among the league's top value creators. Levi's Stadium revenue streams—including a $1.1B naming rights extension with Levi Strauss—combined with deep Bay Area corporate partnerships fueled the delta. On-field excellence matters: the 49ers reached two Super Bowls since 2019, driving premium brand positioning and media rights leverage in the next broadcast cycle.
