What the Odds Say About Iowa State at Arizona
Arizona opens as a heavy favorite in this Big 12 matchup, with the Wildcats priced at -400 on DraftKings and as short as -435 on Kalshi. Iowa State sits as a significant underdog, with moneyline odds ranging from +245 (Kalshi) to +310 (DraftKings). The spread confirms the gap, with Arizona laying 10 points at -110 on both sides via DraftKings.
The books see Arizona as a dominant favorite, but the spread size and moneyline variance across books give bettors a few angles worth examining before kickoff on Saturday, October 25, at 9:00 PM PDT.
Implied Probabilities: Iowa State vs. Arizona
The moneyline odds translate to substantial implied win probabilities for Arizona. At -400 on DraftKings, the Wildcats carry an implied probability of around 80%. Kalshi's -435 line pushes that to approximately 81.3%. Iowa State, priced at +310 on DraftKings, is given roughly a 24.4% implied chance of pulling the upset.
Keep in mind that sportsbook lines include vig, so raw implied probabilities from a single book will not sum cleanly to 100%. To strip out the juice and compare true implied probabilities across books, the Odds Converter makes that quick and straightforward.
Line Differences Across Books
The moneyline gap between books is worth noting. Iowa State bettors get +310 at DraftKings versus +245 at Kalshi. That is a meaningful difference on a dog this size. Shopping to +310 instead of +245 is the kind of edge that compounds over time.
On the Arizona side, DraftKings has the Wildcats at -400 while Kalshi has them at -435. If you are backing Arizona on the moneyline, DraftKings offers clearly better value.
Unibet sits in the middle at -417 for Arizona and +300 for Iowa State, broadly aligning with the market but not offering the best number on either side.
The Spread and Total
DraftKings has Arizona as a 10-point favorite with standard -110 juice on both sides. That is a substantial number for a college football spread, and it reinforces just how lopsided the market views this matchup. Covering 10 points requires a convincing win, which adds a separate layer of analysis beyond simply picking a side.
The total is set at 50.5, also at -110 on both sides. For a Big 12 game, 50.5 is a relatively modest number, suggesting the market expects a controlled game rather than a shootout. Monitor whether that number moves as kickoff approaches, particularly if injury news or weather becomes a factor.

Key Factors That Could Move the Line
Injury and Availability News
With 10 days until kickoff, roster news has not fully settled. Updates to starting quarterback status or key contributors on either side could shift the line meaningfully. A key Arizona injury in particular could tighten this spread quickly.
Home Field and Travel
Arizona is hosting this game, and home field in college football carries real weight. Iowa State is traveling across multiple time zones for an early kickoff, a factor worth considering for a road underdog.
Big 12 Context
Both programs play within the same conference, so familiar film exists on both sides. Iowa State will not be walking into an unfamiliar system. If the Cyclones have been trending upward in recent weeks, that momentum could attract sharp action toward the underdog number.
Public Money and Sharp Movement
A 10-point spread with a recognizable underdog often draws contrarian public interest. Watching whether the spread moves up or down from -10 in the days ahead can signal which side is attracting heavier action. Movement against the public is typically a sharp indicator.
With 10 days of line movement still ahead, this number has plenty of time to shift before kickoff.
