The 49ers' Championship Price Sat Out The Preseason
San Francisco's Super Bowl contract on Kalshi has printed the same quote, four cents bid and five cents ask, on all fifty-two days of the exchange's daily record since July 8. Two other books on the same team at the same exchange changed their quotes seventeen and twenty-one times over the identical days. The difference is not conviction. It is the size of the smallest step each book has.
San Francisco's contract to win the Super Bowl closed at four cents bid and five cents ask last night. It closed there the night before, and on the forty-nine nights before that.
Kalshi's daily record on that contract runs fifty-two entries from July 8 to today, counting this morning's session in progress, and every one of them reads four bid and five ask. Training camp happened inside that run. So did all three preseason games, which San Francisco finished 2-1. The quote was still four bid and five ask at 11:33 a.m. Pacific today, when I pulled it live.
The comfortable reading is that the market spent seven weeks agreeing with itself about the 49ers. That reading is wrong, and the proof is two tabs over on the same exchange.
Over those same fifty-two days, Kalshi's book on San Francisco winning the NFC West changed its quote seventeen times. Its book on San Francisco making the playoffs changed twenty-one times.
Bid, ask, and the ladder underneath them#
Three words first, because the rest of this is arithmetic on top of them.
The bid is the most anybody will currently pay. The ask is the least anybody will currently sell for. You buy at the ask and sell at the bid. A contract quoted at four bid and five ask pays a dollar if San Francisco wins the title, so the market's estimate of that happening sits somewhere inside the one-cent gap between them, and the convention is to call it the midpoint. Four and a half cents. Four and a half percent.
The third word is the one that matters here. A tick is the smallest change a price is permitted to make, and it is set by the venue rather than by anybody's opinion. Kalshi publishes the ladder each of its markets trades on, and on all three San Francisco books it is whole cents. There is no four-and-a-quarter. There is nothing between four and five at all.
What one step costs at four cents, and at fifty-four#
A quote of four bid and five ask is already as tight as the ladder allows. Any move at all has to shift one side by a full cent, which drags the midpoint half a cent whether or not the other side follows.
Half a cent on a midpoint of four and a half is 11.11 percent.
That is the smallest opinion the championship book on San Francisco is capable of having. Not the smallest one it happens to hold today. The smallest one available to it.
Now the same arithmetic on the two books that moved.
The NFC West book has San Francisco at twenty bid, twenty-one ask. Half a cent on a 20.5-cent midpoint is 2.44 percent.
The playoff book has San Francisco at fifty-four bid, fifty-eight ask. Half a cent on a 56-cent midpoint is 0.89 percent.
One team, one exchange, one morning, three instruments. The finest of them reads to nine thousandths of the thing it is measuring. The coarsest reads to a ninth of it. The championship book is twelve times blunter than the playoff book and four and a half times blunter than the division book, and it is the only one of the three that gets quoted in public.
Three Kalshi books on the 49ers, one identical window
Number of times each book's daily closing quote changed between 2026-07-08 and 2026-08-28, from Kalshi's public daily candlestick record, read this morning at 11:33 a.m. Pacific. Same team, same exchange, the same fifty-two daily entries in all three rows. The figure printed after each quote is the smallest midpoint move that quote is able to make.
What the finer books did with the room they had#
The playoff book opened the window on July 8 at fifty-nine bid, sixty ask. It is fifty-four bid, fifty-eight ask now. Along the way its bid touched fifty-three and came back, twelve different quotes in all.
I am comparing bids rather than midpoints on purpose. That book's spread has widened from one cent in July to four cents today, and a midpoint drifts when a spread widens even if nobody has changed their mind. A bid is a firm number. Somebody is standing behind it.
So: the 49ers' playoff bid is down five cents from fifty-nine, which is 8.47 percent of where it started.
Scale that onto the championship contract and the freeze explains itself. Four and a half cents times fifty-four fifty-ninths is 4.12 cents, a move of 0.38. The smallest move the championship book has is 0.5. The revision the finer book registered is worth roughly three quarters of one step on the coarser one, and there is no three quarters of a step. So the quote stayed exactly where it was and looked, to anybody reading only that number, like a market with nothing to say.
The division book is the control that keeps this honest. Its bid wandered from twenty down to eighteen and up to twenty-one across the same weeks, and it finished this morning at twenty, precisely where it began. Net, across the whole window, the NFC West market changed its mind about San Francisco not at all. The championship book agrees with that. It just also agrees with everything else.
The case against all of this, and it has two halves#
The first half is liquidity, and it is the better argument.
The playoff book that moved twenty-one times has traded 21,082 contracts in its entire life and 198 of them in the last twenty-four hours. Thirty-three contracts are resting at its bid right now. Thirty-three. The championship book that moved zero times has traded 3,335,166 contracts in its life and 32,456 in the last day, with 325,049 sitting at the bid and 1,793,863 at the ask.
So a skeptic gets to say that the book that keeps twitching is one almost nobody trades, and the book that sits still is the one with genuine money behind both sides of it. That skeptic is right about the facts and should be listened to. A fair amount of what the playoff market did over seven weeks is thirty-three contracts changing their mind.
It still does not rescue the championship price, because depth and resolution are different properties and one does not buy the other. A book can have two million contracts behind its quote and remain unable to say anything quieter than 11.11 percent, since the ladder is fixed at a cent and the price is four of them. Volume tells you how much money agrees with a number. The tick tells you how precisely that number can be stated. Confusing the two is how a frozen quote gets read as a confident one.
The second half cuts against me, and I would rather print it than have it found.
Making the playoffs and winning the title are not the same question and they do not move one for one. A team that gets worse qualifies less often and also wins fewer games once it is in, so its championship probability should fall by more than its playoff probability, not by the same proportion. My 0.38-cent figure above assumes one for one, which is the most conservative assumption available and therefore the one that most flatters my argument. If the true relationship is nearer two to one, the fair value of the championship contract fell from 4.5 cents to about 3.7, that is more than a full step, and the quote is not too coarse to have moved. It is simply late.
I cannot settle which of those two it is from price data alone, and I am not going to write a paragraph pretending I can. What I will point out is that both readings deliver the same instruction, which is the part a reader can use. The number quoted on every 49ers futures page is either too blunt to carry the market's opinion or behind it. Under neither reading is it a live signal, and it is being read as one.
This is not a San Francisco problem#
Twenty-seven of the thirty-two teams in Kalshi's Super Bowl book are quoted at a price where a single step is at least a tenth of that price. Nine of them sit at zero bid, one cent ask, where one step is the whole contract. Eight teams share San Francisco's exact 4 bid, 5 ask quote and its exact 11.11 percent floor.
Five teams on the board are priced finely enough for their number to register an ordinary week of football.
What one tick is worth, as a share of the price it moves
Smallest possible midpoint move for every quote level in Kalshi's 2027 Super Bowl book, read 2026-08-28 at 11:33 a.m. Pacific. All thirty-two teams are represented; teams sharing a quote share a row. A bar at 100 percent means one step is the entire contract.
There is a tidy irony in the bottom row. The team with the finest ruler on the entire board is the Rams, and the Rams are who San Francisco opens against.
The next thirteen days are the test#
Two dated events sit between now and the middle of September, and they are the largest information events the calendar has to offer before real games start counting.
Sunday, every club in the league cuts from ninety players to fifty-three, by 6 p.m. Eastern, which is 3 p.m. here. Waiver claims settle Monday. Somewhere close to 1,200 roster changes land inside forty-eight hours.
Then, on Thursday September 10 at 5:35 p.m. Pacific, San Francisco plays the Rams at the Melbourne Cricket Ground, the league's first regular-season game in that city, and it is San Francisco's Week 1.
If the 49ers' championship quote is a live instrument, cutting thirty-seven players and playing the most expensive team on the board should be able to move it one cent. If it is what the arithmetic above says it is, it will sit at four bid and five ask through all of it, and a reader watching that number for a signal will spend nineteen days watching a ruler with no markings on it.
No position#
There is nothing to bet here and I am not going to invent one. I have a measurement about an instrument, which is a different object from an opinion about the 49ers, and turning the first into the second requires a title-probability model I do not have and would not ask you to take on faith. The useful output is the reading habit, not a ticket.
If you want the market's live opinion of a Bay Area team between now and Week 1, read the book quoted nearest fifty cents. For the 49ers that is the playoff market, spread and all. The championship number is the one on every odds page precisely because it is the one people want to look at, and it is the least informative of the three.
The call, and what would break it#
Kalshi's daily closing quote on the San Francisco Super Bowl contract will be four cents bid and five cents ask on every one of the nineteen daily closes from today through September 15, a window holding the cut to fifty-three, waiver settlement, and the game in Melbourne. It grades off a single pull of the exchange's own public daily record, and a stranger can run it in one query.
What would make this wrong, and I would rather it were. A blowout in Melbourne, either direction, against a team priced at fifteen cents is the most plausible single cent of movement on the board, and if one game does move a quote that seven weeks of camp could not, then the freeze was never about the ladder and this whole argument needs rebuilding around whatever did move it. A cutdown that costs San Francisco a starter to a waiver claim would do it too. And if Kalshi narrows the ladder below a cent on this book, the floor disappears, the number starts carrying opinions it cannot carry today, and the correct response is to say so rather than to defend the measurement.
The half I am least sure of is the elasticity above, and it is not a small uncertainty. If somebody can show that a five-cent drop in a team's playoff bid ought to cost its title contract more than a full cent, the honest description of this quote stops being blunt and becomes stale, which is a worse thing for a market to be and a better story than the one written here.
The 49ers' Super Bowl contract has closed at four cents bid and five cents ask for fifty-two straight days while two other Kalshi books on the same team changed their quotes seventeen and twenty-one times. The championship book's smallest available move is 11.11 percent of its own price, against 2.44 percent for the division book and 0.89 percent for the playoff book, and the revision the playoff book registered over those fifty-two days is worth about three quarters of one championship step, on the conservative assumption that the two probabilities move one for one. Drop that assumption and the required move clears a full step, in which case the frozen quote is late rather than blunt, which is worse. Twenty-seven of the thirty-two teams on that board have the same problem or worse, nine of them sitting where one step is the entire contract. No position, because a fact about a ruler is not a bet. When a futures price sits still, check whether the market had a way to say anything smaller before you read the stillness as agreement. Nothing here is advice. It is a public record of calls made at stated prices, and every figure in it can be re-pulled by anyone who wants to check me.
