NFL Champion 2027 and the Season Books

Super Bowl LXI caps the 2026-2027 NFL season on February 14, 2027 at SoFi Stadium. Kalshi's KXSB-27 carries the full 32-team championship Categorical at about $1.24M in 24-hour volume—the deepest season-long book on the exchange—after Polymarket retired its overall-winner market and kept only the conference books.

The price and the money name different teams. The Los Angeles Rams lead the championship book at 16% on $37.5k of flow. Houston sits at 5%—and carries $614k, roughly half the entire book on a leg the market gives a one-in-twenty chance. Seattle at 8% has $44.5k and Cincinnati at 5% has $53k. Nothing about the price ordering explains the volume ordering.

Week 1 kicks off in the second week of September, so the pies below reprice on schedule rather than on news for the next few weeks. This workspace was rebuilt this run from six widgets to a full season stack: the championship field, the conference paths, MVP, best record, Offensive Rookie of the Year, and the Chicago relocation book.

Kalshi's KXSB-27 prices the full 32-team field as one Categorical—every team rebased across the whole field, no top-N cap, so dark horses stay visible. Polymarket retired its overall-winner market; its cross-exchange read is the AFC and NFC conference books, which run $4.6k and $763 respectively against Kalshi's $1.24M. Treat the Polymarket pies as structure, not price.

The price leader against the volume leader. The Rams at 16% top the field and also top the best-record book at 13%—the market's most internally consistent read on the board. Houston at 5% carries $614k, half the championship book's entire 24-hour turnover on a leg priced at one-in-twenty.

That gap is the single most interesting number in this workspace. A 5% contract absorbing 50% of the flow is either a large directional position being built quietly or a hedge against exposure held somewhere else. Watch whether the price follows the money once Week 1 starts producing information.

The AFC and NFC conference-winner Categoricals frame the two routes to Inglewood. Polymarket has Buffalo and Baltimore tied at 16% in the AFC—neither is Kalshi's AFC favorite by championship odds—and the Rams at 24% in the NFC, which is consistent with Kalshi. A team's outright-championship probability cannot exceed its conference-winner probability; where Kalshi's pie and a Polymarket conference book imply otherwise, the gap is the tell.

Three season-long award books, all of them flatter than the championship market. MVP runs $91k with Josh Allen at 11%, Lamar Jackson and Joe Burrow at 10% and Justin Herbert at 9%—a genuine four-way field. Best regular season record runs $66k with the Rams at 13%, the only place the championship favorite is also the book favorite.

Offensive Rookie of the Year is the interesting one: $64k, Jeremiyah Love at 19%, and $45.5k of the $64k on Love alone—the same concentration shape as Houston in the championship book, on a name three-quarters of the field has never seen play a professional snap.

Two books that have nothing to do with the standings. Chicago relocation runs $48.7k on a 2028 horizon and prices the franchise leaving Chicago at better than 98%—Indiana at 57%, a new Illinois location at 44%, staying put at 2%. Coach of the Year runs $19k with John Harbaugh at 14%. Off-field books like the relocation market are where prediction markets price things traditional sportsbooks do not list at all.

• Houston is the whole story. 5% price, $614k volume, half the book. Either the price is wrong or the flow is a hedge. This is the cleanest price-versus-money divergence on the exchange right now and it resolves, one way or the other, once games start.
• The Rams are the consensus. 16% to win it all, 13% for best record, 24% in Polymarket's NFC book. Three independent markets agree, which is rarer than it sounds in a 32-team field.
• Preseason pricing is nearly information-free. Until Week 1, a championship pie is a prior. Expect the field to compress sharply through late September as records start meaning something.
• The conference books cannot be arbitraged, but they can be checked. Polymarket's AFC and NFC pies run three orders of magnitude thinner than Kalshi's championship book. When they disagree, Kalshi is almost certainly right—but the direction of the disagreement is still information.
• Rookie concentration mirrors Houston. $45.5k of the $64k Offensive Rookie of the Year book sits on Jeremiyah Love at 19%. Two of the three deepest NFL books on the exchange have most of their flow on a single non-favorite leg.
• MVP is flat and will not stay flat. Four quarterbacks within two points at 9-11%. Award books collapse fast once a season produces a statistical leader.
• Chicago relocation prices at 98% to move. Kalshi lists franchise-relocation contracts on a two-year horizon; no sportsbook does. It is a reminder that the interesting part of event contracts on sports is often not the game.
