Sportsbook hold vs trading fee: two charges, one price

Kalshi's general taker fee hits $1.75 on 100 contracts priced at 50 cents, the top of the range on the fee schedule effective July 7, 2026. Sportsbook hold is not that kind of number. A balanced minus-110 market keeps $10 of every $220 staked, or 4.55%, while Nevada sports pools kept 8.08% of the amount wagered in August 2026. The sportsbook hold vs Kalshi fee question is which of those figures a customer is actually paying, and on what base.

What sportsbook hold counts after the winners are paid

Sportsbook hold is the share of money wagered that a book keeps after paying winners. It is a result, not a figure printed on the board. The Nevada Gaming Control Board's statewide report for August 2026, on the page marked September 21, 2026, put sports-pool win at $32.566 million, 8.08% of the amount wagered, across 185 locations. That percentage mixes every bet type and every result the month produced. American odds of minus 110 mean the customer risks $110 to win $100 of profit, a decimal price of 1.91 because 210 divided by 110 is 1.91. The implied probability is 110 divided by 210, or 52.38%. Two such prices sum to 104.76%. If $110 lands on each side, the book takes $220 and pays $210, keeping $10. 10 divided by 220 is 4.55%, the theoretical hold when the stakes match. Nevada's 8.08% is what those pools kept.

Win amounts in that report are in thousands of dollars, so the row reading 32,566 is $32.566 million. The twelve months ending August 31, 2026 show win of $603.368 million and a win percent of 7.62%. August win was down 22.53% from the year before. None of those percentages is the juice inside one ticket.

Push returns the stake, so that ticket adds nothing to hold. A parlay sits in the same statewide row as a straight, and the summary does not split them. How a sportsbook grades the slip is the step that turns a price into this after-the-fact percentage. The 4.55% exists only in the price shape, and only when the two sides draw equal money.

How the Kalshi fee is calculated on a fill

A Kalshi trading fee is money charged when an order fills, not a margin folded into the contract's price. The fee schedule effective July 7, 2026 gives the general taker charge as the round-up of M times 0.07 times C times P times (1 minus P). P is the price in dollars, C is the contract count and M is a multiplier that defaults to 1. On 100 contracts at 50 cents the product is exact: 0.07 times 100 times 0.50 times 0.50 equals $1.75. The same product at 10 cents is $0.63, because 0.07 times 100 times 0.10 times 0.90 equals 0.63. The help page dated April 19, 2026 says Kalshi makes money by charging a transaction fee on the expected earnings on the contract. The schedule lists no settlement fee and no membership fee. The $1.75 is paid whether the contract later pays $1 or expires at zero.

At 1 cent the same product is $0.0693, and the round-up lifts it to the $0.07 floor on 100 contracts. At 90 cents it is $0.63 again, because price times (1 minus price) peaks at 50 cents. The schedule puts the fee plus the position cost on a centicent, a hundredth of a cent. The 50-cent case is already an exact $1.75.

ACH deposits from a bank account carry no fee on that schedule. The $1.75 trading fee is the charge that belongs beside hold.

Sportsbook hold vs Kalshi fee when the price is a coin flip

Buying 100 contracts at 50 cents costs $50 before the fee. The taker fee under the July 7, 2026 formula is $1.75, so the all-in cost is $51.75. If the contract pays, the position receives $100 and profit is $48.25. If it expires worthless, the loss is the whole $51.75. Divide the all-in cost by the $1 payout and the hurdle is 51.75%, even though the contract price itself read 50 cents.

Set the same coin flip against minus 110. The customer risks $110 to win $100 of profit. At a true 50% chance, the expected return is half of $210, or $105. That is $5 short of the $110 laid out, and $5 divided by $110 is 4.55% of the stake. The book does not send an invoice for the 4.55%. The price is the invoice.

That one-time reading dies on the exit, a second fill with its own fee. At 70 cents the formula charges $1.47 on a $70 position: 0.07 times 100 times 0.70 times 0.30. A 70-cent contract is not a minus-110 twin.

A book that builds one number for a whole series still hides the margin inside that number. Sportsbook hold vs Kalshi fee only makes sense once each figure names its base: a $1.75 toll on a fill is not a 4.55% share of stakes.

Charge	When it is taken	Worked figure	Base
Theoretical hold, minus 110 both sides	After a winner is paid, and only if stakes match	$10 kept from $220, or 4.55%	Money taken in on that market
Nevada sports-pool win percent	After the month's results	8.08% in August 2026, win of $32.566 million	Statewide sports-pool handle
Kalshi taker fee, 100 at 50 cents	When the order fills	$1.75 on a $50 position	July 7, 2026 formula, M equals 1
Kalshi taker fee, 100 at 10 cents	When the order fills	$0.63 on a $10 position	Same formula, same effective date

Nevada figures: Gaming Control Board monthly revenue report, August 2026, page marked September 21, 2026. Kalshi figures: fee schedule effective July 7, 2026. The minus-110 row is that price shape, not a live ticket.

Why August's 8.08% is not the juice in the ticket

Hold moves when favourites win and when one side of the book is heavier. Nevada's 8.08% in August 2026 sat above the 4.55% in a balanced minus-110 market, and the twelve-month figure on the same row was 7.62%. Read as sportsbook hold vs Kalshi fee, that gap is results and mix, not a second copy of the juice.

The New Jersey Division of Gaming Enforcement release of September 16, 2026 put August sports-wagering gross revenue at $61.4 million, down 25.0% from $81.9 million. Issued under interim director Mary Jo Flaherty, it ties the drop to a later fall sports calendar, including college football, and to a lower win percentage. Year-to-date gross revenue through August was $671.4 million, down 5.3% from $708.7 million. It states the direction of that win percentage and does not reprint the 4.55%.

"Unless there are fundamental changes happening on a frequent basis in sports, structural hold and hold should converge over time."

Jason Robins, chief executive, DraftKings (Sports Business Journal, May 16, 2025)

Sports Business Journal reported DraftKings' first-quarter 2025 hold at 9.5%, against a 10.4% structural hold. That split matches Nevada's month: a realised 8.08% against the margin the prices were built to keep. A later look at how a reported sports margin moved is another quarter. It does not turn 9.5% into a fee.

Maker orders and the fill that pays no fee

A taker order matches immediately. A maker order rests until someone else trades against it. Kalshi's help page says maker fees, where they exist, are charged only when that resting order executes, and that cancelling a resting order carries no fee. The maker formula on the July 7, 2026 schedule uses 0.0175 in place of 0.07, and the maker multiplier defaults to zero unless the series says otherwise. On an ordinary market, a resting order pays no trading fee.

Zero is not on the sportsbook side of a sportsbook hold vs Kalshi fee comparison. No second order type removes the 4.55% inside a balanced minus-110 market. Some series do list maker fees, and there the charge uses 0.0175 rather than a waiver. The default is the point: most resting orders are not billed the general trading fee.

An exchange can leave the screen. Matchbook's move to buy Betdaq and close that exchange does not change the 0.07 coefficient. Nevada's $32.566 million stays on the page after a book closes its window.

Where vig and the trading fee sit in the rulebook

Kalshi lists event contracts as a designated contract market supervised by the Commodity Futures Trading Commission. A Nevada sportsbook wager is a gaming product under the Nevada Gaming Control Board, and the same activity in New Jersey is reported to the New Jersey Division of Gaming Enforcement. The $1.75 line item and the 8.08% win percent are charges under different licences.

Public inspection of the proposal to write event contracts into the swap definition, RIN 3038-AF82, is scheduled for the Federal Register on October 19, 2026. The summary names sports contracts among the event contracts it would include. A footnote says the addition would not reach casino-style gambling products, which a separate rulemaking treats as not swaps. Letters go to Christopher Kirkpatrick, secretary of the Commission, Three Lafayette Centre, 1155 21st Street NW, Washington.

In that text the Commission describes market makers earning the spread from peer-to-peer volume, "unlike traditional sports betting where centralized sportsbooks extract a static 'vig' from fixed odds." The contrast is about who sets the price. It does not measure the $1.75 fee or the 8.08% hold.

"When a customer wins on a traditional sportsbook, they block that customer because those winnings are coming from the business model."

Tarek Mansour, chief executive, Kalshi (Sports Business Journal, April 8, 2026)

Mansour said that on The Axios Show. The sentence is about who books the win, the house or another trader. It does not price the $1.75 fee against an 8.08% monthly hold. Limiting a customer is not, by itself, a hold figure.

Sportsbook hold vs Kalshi fee on a round trip

Selling the same 100 contracts at 50 cents, again as a taker, bills a second $1.75. The round trip costs $3.50, which is 7% of the $50 premium, for two fills at one price. Exit at 60 cents instead and the formula bills $1.68: 0.07 times 100 times 0.60 times 0.40. A maker exit, where the maker multiplier is still zero, adds $0 at that step.

Holding to settlement is the cheap path on the July 7, 2026 schedule, because settlement carries no fee. The entry fee is paid once, and the contract then pays $1 or pays nothing. A sportsbook slip has no second line item when it is graded, because the charge was already inside the odds. The 8.08% cannot be read before the month closes.

FAQ

What is sportsbook hold?

Sportsbook hold is the percentage of money wagered that a book keeps after it pays winners. Nevada's Gaming Control Board put the statewide sports-pool win percent at 8.08% in August 2026, on win of $32.566 million. That is a result. The theoretical hold of a balanced minus-110 market is 4.55%, or $10 kept from $220 when equal stakes land on each side. The monthly figure mixes bet types and results. The 4.55% is only the price shape.

How does Kalshi calculate a trading fee?

The fee schedule effective July 7, 2026 sets the general taker fee as the round-up of M times 0.07 times the number of contracts times the price times (1 minus the price), with M usually 1. On 100 contracts at 50 cents that product is $1.75. On 100 contracts at 10 cents it is $0.63. The charge is highest near 50 cents and smaller near 1 cent or 99 cents. The help page calls it a transaction fee on the expected earnings on the contract.

Is a Kalshi fee the same thing as vig?

No. Vig, or juice, is margin built into a sportsbook price. Minus 110 on both sides implies 52.38% each side and keeps about 4.55% if the book is balanced. A Kalshi fee is a separate toll on the fill, calculated from the published formula, and the contract price is the traded price. The $1.75 on a $50 position is not 4.55% of anything in that trade. Comparing the two without naming the base mixes a toll with a share of stakes.

Does the fee come off again when a contract settles?

The July 7, 2026 schedule says there is no settlement fee. The trading fee is paid when the order fills, whether the contract later pays $1 or pays nothing. A second trade, including a sale before settlement, is a new fill and can carry a new fee. A resting order on a market whose maker multiplier is zero pays no trading fee when it executes. Cancelling that resting order, the help page says, costs nothing.

Comment letters on the proposal are due 30 days after Federal Register publication on October 19, 2026, under RIN 3038-AF82. That clock does not rewrite the July 7, 2026 fee formula, and it does not rewrite Nevada's August win percent of 8.08%. The sportsbook hold vs Kalshi fee comparison still turns on the fill and the payout.
