Since Caitlin Clark joined the WNBA in 2024, attendance and TV audience have both risen sharply. The most defensible broad summary from recent reporting is that league-wide TV ratings were up about 23% year over year , and the WNBA set a new single-season attendance record with about 2.5 million total fans in 2025.

Attendance

The clearest league-wide attendance figure I found is that the WNBA drew 2.501 million fans across 226 games in 2025 , which was described as a record. Another report said the league reached 2.43 million before the end of the season, also marking a record pace. That suggests a major increase from the pre-Clark era, but the exact percentage depends on what baseline season you compare against. A practical way to think about it:

  • League total attendance: record highs, roughly 2.4M–2.5M in 2025.
  • Clark/Fever effect: her games have been a major driver of that surge, with arena moves and sellouts frequently reported.

TV Audience

On the television side, NPR reported that WNBA TV ratings were up 23% across the board in 2025. That is the cleanest league-wide number in the results I found. Other coverage also says viewership and attendance continued to rise even when Clark was absent, which suggests the growth is broader than just one player, though she remains the biggest single draw.

What it means

In plain English, the league has gone from “strong growth” to “record-setting” since Clark arrived. The safest shorthand is:

  • Attendance: up enough to reach record totals, around 2.5 million fans in a season.
  • TV audience: up about 23% year over year.

Bottom line

A concise answer would be: WNBA attendance has climbed to record levels, and TV viewership is up roughly 23% since Caitlin Clark entered the league, with Clark widely credited as a major catalyst.
