The WinBA Index: the WNBA’s top players for August 2026

Olivia Miles leads at 88 from A'ja Wilson at 85, with 188 qualified players ranked on PropBetEdge’s winning-impact rating for August 2026.

By the PropBetEdge WNBA Newsroom Published Updated Source data as of Aug 31, 8:00 PM ET

Olivia Miles finishes August 2026 at the top of WinBA Score, PropBetEdge’s winning-impact rating, with a mark of 88 for the Minnesota Lynx on 19.5 points, 4.8 rebounds, 6.1 assists a game.

A'ja Wilson is next at 85, 2.6 points back — the clearest separation at the top of the board this month.

This edition of The WinBA Index was reconstructed from PropBetEdge's archived game record. The board below is the August 2026 ranking as it stood at the close of the period; the article itself was published later, and its publication date reflects that.

WinBA Score is built only from completed WNBA games: Box Impact (points plus 1.2 times rebounds plus 1.5 times assists) measured per 36 minutes against the league, the player’s win rate, the share of her production that came in wins, and her court share. It is an association-with-winning index, not a causal estimate of wins added. 188 players qualified for the league ranking, which takes at least 10 appearances or 250 minutes.

What the rankings say

The top 10 won 68% of the games they played. Because a quarter of WinBA Score is win rate and a fifth is the share of production that came in wins, the board rewards players whose output arrives in victories — which is why it is read as a winning-impact rating rather than a volume leaderboard.

Every player in the top 10 sits at or above the 87th percentile of Box Impact per 36, so none of these ratings rests on playing time alone.
