Kalshi spread & total ladders priced out of order
Every Kalshi spread and total ladder in 7 leagues — NFL · CFB · NBA · NHL · CBB · EPL · UCL — checked every scan for strikes priced out of order, with the contract linked on every row.
Quick Answer
Kalshi lists a spread or total as a ladder of strikes on one side of one game — measured November 9, 2026, about 33 spread strikes and 29 total strikes per NBA game, 25 and 19 per NFL game. A higher strike can never be worth more than a lower one on the same side; when Kalshi's book says otherwise it is here, labelled LOCKED (true arbitrage), INVERTED (crossed mids on real books) or WIDE (a market-making seat). Fees are Kalshi's published 7% × price × (1 − price) per contract at the fill; the board sorts and tiers on the net figure. The full board is free; Pro adds the resting orders, net-of-fee edge and ¼-Kelly size.
Kalshi spread & total ladders priced out of order
The same rule as the all-venue board, one order book at a time: a higher strike can never be worth more than a lower one on the same side of the same game. This page reads only Kalshi's ladders — NFL · CFB · NBA · NHL · CBB · EPL · UCL — and sets each strike beside the other venues where they list it. Other venues: Novig · Polymarket US.

How the Kalshi scan works
Every scan pulls every open market in Kalshi's 21 ladder series through the public REST API, groups them into one ladder per game, side and market kind, and checks every adjacent pair. Kickoff is the scheduled start (Kalshi's own timestamp runs three hours late), and a game that has started is dropped.
The same strikes are then set beside the other venues: a CROSS is the ask on one venue under the bid on another net of both venues' fees, a GAP two mids three cents or more apart on real books. The integrity tiles above the board and the depth table below it are measured on the latest scan, never quoted from a brochure.
Frequently Asked Questions
What does Kalshi list as a ladder?
Three market families per league, 21 series in all: the game winner, a spread ladder ("Atlanta wins by over 7.5 points", then 9.5, 11.5 …) and a total ladder ("Over 229.5 points", then 231.5 …). Each strike is its own contract with its own order book. Measured November 9, 2026, Kalshi listed about 33 spread strikes and 29 total strikes per NBA game, 25 and 19 per NFL game, 29 and 19 per college football game, 4 and 9 per NHL game and 13 and 15 per college basketball game; the live depth table on this page is the current count.
What does a Kalshi fill cost pregame?
7% × price × (1 − price) per contract, charged to the taker at the fill, win or lose — about 1.75¢ on a 50¢ contract and near zero at the extremes. Most Kalshi series charge makers nothing; a few carry a maker fee at a quarter of the taker rate, and the scanner reads each series' own multiplier from the API. Every row here reports the gross edge free and nets the fee on both legs before it tiers.
How do Kalshi's books differ from Novig's and Polymarket US's?
Kalshi quotes whole cents on a $1 contract with a two-sided book at most strikes and real traded volume we can show. Novig quotes to the millicent on 1¢ contracts and publishes size at the quote rather than volume; its pregame game lines carry no fee at all. Polymarket US quotes quarter-cent ticks on a $1 contract with a taker fee of the same shape as Kalshi's and publishes no liquidity figure. The scanner reads all three on their own clocks and shows each venue's ladder integrity side by side — the Kalshi tiles here, and the Novig and Polymarket US tiles on their pages.
How does Kalshi compare on the same strike?
When Novig or Polymarket US lists the same game, side and strike, the scanner matches it to the Kalshi contract and reports CROSS (the ask on one venue sits under the bid on the other, net of both venues' fees — one leg per venue) or GAP (the two mids are three cents or more apart on real books, for information). A Kalshi–Novig cross carries the two-venue order pair for Pro; a cross that touches Polymarket US is shown as prices and arithmetic only.
