BREAKDOWN · MODEL ANALYSIS

The model makes M. Keys the favorite with a 64% win probability, against K. Siniakova's 36% — a solid favorite, though Siniakova keeps real chances. Converted to odds, that probability is worth about @1.57; the offered odds are around @1.23 (a 81% implied), slightly below the market, so the model is a touch more cautious.

Several factors explain the number: #24 vs #44 (better ranked); 7/10 in recent matches; 1-0 in favor; 62% career on the surface.

Read it with perspective. Our probability is calibrated — when the model says 64%, that outcome happens roughly that percentage of the time, with ~64% out-of-sample accuracy — but being the favorite is not being the winner: roughly 36 out of every 100 times Siniakova wins. The model also tends to agree with the market, so the odds already capture almost all the edge: don't take it as a sure value.
