BREAKDOWN · MODEL ANALYSIS

The model makes E. Rybakina the favorite with a 61% win probability, against I. Swiatek's 39% — a solid favorite, though Swiatek keeps real chances. Converted to odds, that probability is worth about @1.64; the offered odds are around @2.21 (a 45% implied), slightly above the market, so the model is a touch more optimistic.

Several factors explain the number: #2 vs #8 (better ranked); 5-5 even; 73% career on the surface; model 61% vs market 45% → the model sees it as more likely than the odds.

Read it with perspective. Our probability is calibrated — when the model says 61%, 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 39 out of every 100 times Swiatek 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.
