BREAKDOWN · MODEL ANALYSIS

The model makes I. Swiatek the favorite with a 54% win probability, against J. Pegula's 46% — a tight match, without a wide margin. Converted to odds, that probability is worth about @1.84; the offered odds are around @1.39 (a 72% implied), slightly below the market, so the model is a touch more cautious.

Several factors explain the number: #5 vs #3; 7-3 in favor; 79% career on the surface; model 54% vs market 72% → the model sees it as less likely than the odds.

Read it with perspective. Our probability is calibrated — when the model says 54%, 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 46 out of every 100 times Pegula 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. Watch out for: The opponent is ranked higher (#3).
