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, +335 means a $100 bet profits $335 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.

One Game, Two Prices Worth Taking
The market has San Francisco at -335 on the moneyline (a moneyline is simply a bet on who wins the game, no margin required). That is a heavy favorite, about 77% to win once the bookmaker's cut is stripped out. Here is the odd part. The two prices on this board that pay more than the market's own read are the Arizona moneyline and the San Francisco spread, sitting on opposite sides of the same game. That happens when different books post different numbers, and it is exactly why we shop. Kickoff is Sunday, September 27, 2026 at 4:05 PM ET at Levi's Stadium.
The Matchup
The Arizona Cardinals are 1-1 and sit 4th of 4 in the NFC West. The San Francisco 49ers are 2-0 and sit 2nd of 4 in the same division. Division road games at Levi's Stadium are rarely comfortable for a team still finding itself, and the number reflects that: 49ers vs Cardinals opens with San Francisco laying more than a touchdown.
Players to Watch
Brock Purdy has been efficient for San Francisco: 45 of 56 for 492 yards, 5 touchdowns and 1 interception. That is an 80% completion rate and roughly 8.8 yards per attempt, which is how a team builds two-score leads without needing long drives. Jacoby Brissett leads Arizona at 44 of 65 for 372 yards, 2 touchdowns and 1 interception. Nearly the same number of completions, 120 fewer yards, and 5.7 yards per attempt. That gap in yards per throw is the whole spread in a nutshell.
The Numbers
Moneyline: Arizona Cardinals +335, best at BetRivers. A $100 bet profits $335.00 when it wins and loses $100 when it does not. Break-even is 23%, meaning the bet must win 23 times in 100 to stay level. Point spread (a bet on the margin, not the winner): Arizona +7.5 at -105 (Hard Rock Bet) wins if the Cardinals win outright or lose by 7 or fewer, and it loses on an 8-point loss. There is no push at a half point.
Injuries
Six names are listed. San Francisco: Mike Evans questionable, which means genuinely uncertain and nothing more, Demarcus Robinson on injured reserve, James Thompson Jr. out. Arizona: Roy Lopez questionable, Max Melton questionable, Dadrion Taylor-Demerson out. Final designations land before Sunday's 4:05 PM ET kickoff.
