What the Odds Say
Boise State enters this Mountain West matchup as a heavy favorite over Washington State. The Broncos kick off Saturday, October 24 at 3:00 PM PDT in Pullman, with the market pricing this as a lopsided affair. Moneyline odds across most books cluster around Boise State -500, implying roughly an 83% win probability. Washington State sits in the +370 to +410 range, depending on where you shop.
The spread consensus lands at Boise State -12.5, with the range across books running from -11.5 to -13.5. That two-point window matters when you're talking about a game likely decided by a couple of scores. Bettors who want the best number on the Broncos should check BetOnline.ag and BetUS, both posting -11.5. Those looking to back Washington State getting points will find the most generous number at LeoVegas at +13.5, a full two points better than the tightest spread in the market.

Spread Market Breakdown
The spread range worth paying attention to:
- Tightest Boise State line: -11.5 at BetOnline.ag, BetUS, and Kalshi
- Widest Boise State line: -13.5 at LeoVegas and Marathon Bet
- Consensus: -12.5 at DraftKings, FanDuel, Caesars, 1xBet, Pinnacle, and several others
Pinnacle is often used as a sharp reference point, and they have Boise State -12.5 at -104, a notably better price than the standard -110. That suggests the market is fairly settled at -12.5 as the true line, with the juice leaning slightly toward the Broncos covering.
The two-point gap between the sharpest and softest lines also creates middling potential. Grabbing Washington State +13.5 at LeoVegas and Boise State -11.5 at BetOnline.ag or BetUS gives you a two-point window where a Broncos win by exactly 12 or 13 cashes both sides. The Middle Calculator can help you size those bets and calculate the potential payout.
Totals: Over/Under Sitting at 51 to 51.5
The over/under is clustered around 51 to 51.5, with most major US-facing books posting 51.5. BetRivers is the outlier on the low end at 50.5, while ProphetX shows 52.5, though their pricing structure is not representative of the main market.
Boise State has one of the more productive offenses in the Mountain West this season, which helps explain why the total sits in the low 50s. Washington State's offense has been less consistent since leaving the Pac-12, so the total may hinge largely on how many points the Broncos put up and whether the Cougars can keep pace.
What to Watch Before Saturday
A few factors could shift this line before kickoff:
Injury news. Boise State's offensive efficiency is tied closely to their skill players staying healthy. Any notable absence on either side could move the spread by a point or more by Saturday morning.
Public money vs. sharp action. A large spread on a Group of Five matchup can attract lopsided public money on the favorite. Movement toward -13 or -13.5 without injury news likely signals public pressure. Movement back toward -11.5 could indicate sharp disagreement.
Home field. Washington State is playing at home in Pullman, historically a difficult environment for visiting teams. That factor may already be baked into the line, but it's worth watching whether the number shifts as game week unfolds.
