Social media superstars: Followers vs. engagement
When it comes to reach, the NBA is the undisputed social media champion. With more than 280 million combined followers across Instagram, X, and Reddit, the league dominates the conversation online. The NFL trails with over 152 million followers, followed by the MLB (86 million) and NHL (60 million).
However, follower count alone doesn't tell the full story. When measuring average engagement per post, MLB fans come out swinging. Across all platforms, baseball teams had the most active fan interactions, especially on Instagram, where MLB's average engagement rate hit 1.37%. These fans might not post the most memes or go viral as often, but when their team posts, they show up strong.
This suggests that while leagues like the NBA have broader audiences, MLB teams may have tighter-knit communities with stronger per-post loyalty, a key insight for brands prioritizing quality interactions over sheer reach.

Instagram influence: Who makes the most money per post?
Beyond bragging rights, social media engagement translates into real-world value, especially for brands. Using engagement rates, posting frequency, and industry-standard CPM rates, we calculated the estimated worth of a single sponsored Instagram post for every major U.S. sports team:

- Los Angeles Dodgers (MLB): $51,300

These numbers aren't just vanity stats. For influencers and teams alike, sponsored content has become a key revenue stream, and sports franchises with highly engaged audiences offer a powerful platform for marketing. The Dodgers' dominance is especially notable, proving that a strong brand, loyal fans, and regular content can drive major advertising value.
Engagement is the new home field advantage
In the age of digital fandom, it's not just about how many followers a team has. It's about how often those fans engage. From the Dodgers' social media dominance to the Bills' Instagram energy, today's top teams are building influence far beyond the playing field.
For franchises, this means more partnership opportunities and brand equity. For fans, it's a chance to shape the narrative, one like at a time. And for everyone else? It's proof that in sports, the conversation never ends. It just moves online.
Methodology
To conduct this study, we analyzed the official social media accounts for every U.S.-based franchise across the NFL, NBA, MLB, and NHL. We pulled like and comment data from Instagram, X, and Reddit and reviewed every public post made throughout 2025.
Engagement rate was calculated using the sum of likes and comments divided by total followers. This allowed us to compare teams on a per-post basis, regardless of posting frequency or account size.
To estimate the monetary value of a sponsored Instagram post, we used a formula factoring in:
- Engagement rate per post
- Scarcity factor, based on average monthly posting frequency
- A $25 CPM (cost per 1,000 followers) benchmark, which reflects industry averages for influencer marketing
Only verified team accounts were included in the analysis, and engagement rates were averaged across the full calendar year to ensure consistency.
