Exchange buyers before kickoff: which side buyers took (Kalshi, Polymarket (international), Novig, ProphetX)
These are exchange trades, not sportsbook bets. On an exchange every trade has a buyer and a seller, so this shows which side buyers paid for.
How to read these numbers
Kalshi, Polymarket (international) and Novig publish every trade with the side the buyer took. ProphetX carries its trade fills the same way; a line with no captured fill shows dollars matched only. Trades is each side's share of the trades we read since we began reading the market and Money is its share of the dollars buyers paid. Markets with fewer than 10 trades or under $500 traded are left out; markets under 30 trades or $5,000 are labelled Light trading, because a few buyers can move the percentages a long way.

📘 New to betting? Two-minute translation. A moneyline bet is picking who wins, nothing else. In this game, +205 means a $100 bet profits $205 if it wins. The spread is a head start: -7.5 must win by 8+, while +7.5 cashes by losing by 7 or fewer (or winning). The total is combined points by both teams, over or under the books' number. +EV means the price pays better than the market-implied fair odds (vig removed); consistently taking better prices raises your expected return over time.

The Sharpest Number on the Board Is the Small One
Illinois is a 67 percent favorite in this market, and almost nobody will argue with that. The argument is about the five and a half. That gap is small. It is also the only edge on this board, and finding it is the whole job.
The Matchup
Duke vs Illinois kicks off Saturday, September 12, 2026 at 3:30 PM ET at Gies Memorial Stadium, Week 2 of the 2026 regular season. Both teams are 1-0 as of publication. Illinois is home, Illinois is the favorite, and the sportsbooks have set the price at Illinois Fighting Illini -210 on the moneyline (a bet on the outright winner, no points involved). Flip the search and read it as Illinois vs Duke and nothing changes: the Fighting Illini are laying the points, the Blue Devils are getting them. No season series information is given here, so we judge this one on the numbers in front of us.
Players to Watch
Katin Houser leads Illinois with a 13-of-17 line for 182 yards and 3 touchdowns. That is 10.7 yards per attempt and a 76 percent completion rate, the kind of efficiency that ends drives in the end zone instead of at the 30-yard line. Walker Eget leads Duke at 13-of-26 for 131 yards, roughly 5.0 yards per attempt. That is the mismatch the market is pricing: one quarterback converting at a high rate per throw, one grinding. If Eget's per-attempt number climbs even a little, a 5.5-point game gets very tight very fast.
The Numbers
Start with the moneyline. Illinois Fighting Illini -210 at Bally Bet means a $100 bet profits $47.62 when it wins and loses $100 when it does not, and it needs to win 67.7 percent of the time just to break even. Duke Blue Devils +205 at ProphetX means a $100 bet profits $205.00 when it wins and loses $100 when it does not, break-even 32.8 percent. The spread is the margin bet.
Duke +5.5 at +108 (ProphetX) wins if Duke wins outright or loses by 5 or fewer, and it loses on a 6-point loss. There is no push at a half point, so no ties and no refunds. Illinois -5.5 at -110 (theScore Bet) wins only if the Illini win by 6 or more; a 5-point win loses. The total is 51.5 combined points, Over -104 and Under -101, both best priced at ProphetX. Those are the best prices across the books we track, and shopping for them is the edge.
