Caleb Williams MVP odds jump to 13% on Kalshi after Bears debut
Kalshi traders repriced NFL MVP odds after Caleb Williams' Week 1 debut, pushing him to 13% and tying him with Josh Allen on September 13. Lamar Jackson sits at 9%. The shift came one day after Kalshi Sports posted preliminary rankings showing Allen and Joe Burrow at 11%, with Jackson at 10%, Justin Herbert at 9%, and Brock Purdy at 7%. The rapid repricing reflects live market reaction to the Chicago Bears quarterback's first NFL start.
The Williams spike is a sentiment signal, not a liquidity event. No volume or fill data accompanies the price post, so traders cannot judge whether a meaningful order book backs the 13% print. Kalshi's sports markets remain thin surfaces where retail flow moves prices without institutional absorption.
The platform's real test is whether Sunday night order books on featured games like Cowboys-Giants can hold steady under live NFL flow. Novig's $125 million first-week pace and Polymarket's established pools are pulling serious volume elsewhere. Traders measuring fill quality across venues will route size to deeper books. A slippage gap in a spotlight game would push traders toward competitors before Kalshi can rebuild depth.
