Fan Engagement > Our Thinking > Report finds sports organisations only know 24% of their fanbase
Key insights
- Sports organisations only know around 24% of their total fanbase by name and contact detail, leaving the vast majority of their audience anonymous and unmonetised.
- One in three rights holders estimates losses of between $1 million and $5 million a year directly attributable to anonymous fans.
- 62% of sports organisations believe they lose more than $100,000 annually because they cannot reach, convert, or monetise their majority audience.
- Challenger sports are adapting faster than top-tier leagues: over a third now tie more than half of their sponsorship renewals directly to fan engagement and first-party data.
- The next competitive advantage in sport will not come from rights ownership alone, but from the depth of fan relationships and the quality of first-party data behind those rights.
Dizplai, the strategic growth partner that helps organisations unlock audience engagement, has released the Anonymous Fan Index, the first independent industry report exposing the financial impact of ‘anonymous fandom’ across global sport.
The findings, taken from a hand-selected group of senior industry experts, reveal a rapidly widening gap between the attention sports organisations generate and the revenue they can actually capture, with one in three rights holders now estimating losses between $1 million and $5 million a year due to anonymous fans.
Across the full sample of experts from leading leagues, clubs, federations and rights owners, 62% believe they lose more than $100,000 annually because they cannot reach, convert or monetise the majority of their audience.
Dizplai CEO, Ed Abis, describes fan anonymity as: “the biggest invisible revenue leak in modern sport – a board-level issue hiding in plain sight.”
Anonymous fans are a commercial blind spot the industry can no longer ignore
While sport continues to push out more content and negotiate bigger rights packages, the report finds that organisations only know around 24% of their total fanbase by name and contact.
This blind spot is hitting the bottom line: sponsorship value is dropping as brands demand measurable engagement, renewals are stalling without digital evidence, and long-term revenue is shrinking due to low conversion from anonymous fans.
Abis says the findings should be a wake-up call: “This isn’t a data issue. It’s a commercial one. Rights holders aren’t losing fans – they’re losing the ability to know them. And if you don’t know them, you can’t grow them.”
Giants are vulnerable, and underdogs have an opening
The Index reveals that top-tier leagues and challenger sports face many of the same obstacles. Both only identify roughly a quarter of their audience, and both sit mostly in ‘beginner’ or ‘developing’ stages of fan-data maturity.
But underdogs are adapting faster. According to the report, over a third of challenger organisations now tie more than half of their sponsorship renewals directly to fan engagement and data.
This pressure is forcing challenger sports to innovate and giving them an unexpected advantage.

The next competitive edge: fan relationships, not rights
The report points to a clear shift: competitive advantage in sport will no longer come from rights ownership alone, but from the depth of the relationships behind those rights. As organisations look ahead to the next 24 months, they are prioritising stronger fan data foundations, more direct fan connections, and interactive live experiences that create measurable value for sponsors.
Abis believes a mindset shift is overdue: “Sport built its empire on reach, but the next era will be built on relationships. If you don’t own your fans, you don’t own your future.“

FAQs
The Anonymous Fan Index is Dizplai’s first independent industry benchmark measuring how well sports organisations identify, engage, and monetise their fans. It draws on responses from senior leaders across 50 sports organisations including rights holders, leagues, clubs, and federations, and examines fan data maturity, revenue leakage, sponsorship pressure, and future investment priorities.
The report finds that sports organisations typically know only around 24% of their total fanbase by name and contact detail. The remaining 76% are anonymous: they watch, attend, and follow, but the organisation has no way to reach them directly, personalise their experience, or convert their interest into measurable commercial value. This gap is estimated to cost rights holders between $100,000 and $5 million a year.
Anonymous fans cannot be reached directly, personalised for, or converted into paying customers or sponsor proof points. As brands increasingly demand measurable fan engagement data at sponsorship renewal, organisations that cannot demonstrate who their audience is and how they interact are losing commercial ground to those that can. Fan engagement without first-party data is reach without relationship.
The report finds that challenger sports are adapting faster than top-tier leagues, with over a third now tying more than half of their sponsorship renewals directly to fan engagement and first-party data metrics. Faced with fewer legacy systems and more pressure to prove value quickly, challenger organisations are building data capture into fan experiences earlier and more deliberately than their larger counterparts.
The most effective approaches create a genuine value exchange: giving fans something meaningful in return for identifying themselves, whether that’s exclusive access, personalisation, early ticket priority, or community recognition. Interactive fan engagement tools, owned community platforms, and live event data capture all create natural moments where anonymous fans choose to become known contacts. The Anonymous Fan Index outlines the maturity stages organisations typically move through and what investment priorities make the biggest difference.
