Las Vegas Raiders vs Los Angeles Chargers — Win Probability

Raiders' Upset Win Over Chargers Defied Model and Market Alike

Las Vegas came to Los Angeles as a decided underdog on every metric—the model gave them just a 31% win probability pregame, while the market had Los Angeles favored by 6.5 points. The simulation projected a Chargers victory by 6.6 points, with an expected final score of 25–18.5 in Los Angeles' favor.

Instead, the Raiders won 26–14, flipping the script entirely. The 12-point margin of victory was 18.6 points wider than what the model forecast. This was a substantial miss, not a marginal one.

The upset itself was significant—Vegas at 31% implied roughly a two-in-three chance the Chargers would prevail—but the magnitude of the Raiders' dominance compounded the projection error. The model expected a close, low-scoring affair with Los Angeles in control. What occurred was a comfortable Raiders win that never felt competitive.

For a model built to reflect pregame information and market consensus, this outcome represents a genuine gap. The Chargers and oddsmakers both underestimated Las Vegas's capacity to control this game. Whether that reflects a flaw in how the model weighted available data or simply an unpredictable single-game variance remains the open question that every projection encounters. The 31% probability for Vegas wasn't zero—upsets happen—but the size of this one, 18.6 points beyond expectation, suggests something about either the Chargers' actual weakness or the Raiders' actual strength went undetected in pregame analysis.

The Raiders improved to 2–0; the Chargers fell to 0–2. Both records represent outcomes the model saw as unlikely given its pregame assessment.
