The simple version

An exchange of this kind sits between buyers and sellers and guarantees that the deal completes. For that it charges a set amount per contract rather than a slice of the value.

The amount is tiny and the count is enormous. Well under a dollar per contract, tens of millions of contracts a day.

There is a second business running alongside it. The exchange holds the record of what everything traded at, and it licenses that record out.

The numbers

• All figures are from CME Group Inc.'s third quarter 2026 results, furnished as exhibit 99.1 to a Form 8-K filed with the Securities and Exchange Commission on October 21, 2026, accession number 0001156375-26-000065, period of report October 21, 2026. Dollar amounts are in millions as the filing states them
• The filing states that average daily volume for the third quarter of 2026 climbed to a third-quarter record of 29.4 million contracts, and that non-United States average daily volume reached a third-quarter high of 9 million contracts (same filing)
• The filing states that the total average rate per contract was $0.679 (same filing)
• The filing states that market data revenue totaled a record $243 million for the third quarter of 2026, an increase of 20 percent (same filing)
• Income statement, quarter ended September 30, 2026 against the same quarter of 2025: clearing and transaction fees $1,378.1 against $1,227.9; market data and information services $243.1 against $202.5; other $116.1 against $107.2; total revenues $1,737.3 against $1,537.6 (same filing)
• Income statement, nine months ended September 30, 2026 against 2025: clearing and transaction fees $4,273.2 against $3,953.2; market data and information services $705.3 against $595.1; other $345.1 against $323.6; total revenues $5,323.6 against $4,871.9 (same filing)
• Expenses for the quarter ended September 30, 2026 against 2025 include compensation and benefits $234.3 against $237.6, technology $80.9 against $71.4, and professional fees and outside services $31.1 against $36.7 (same filing)
• The filing states that the quarter generated a new high of $100 billion in average daily capital efficiencies (same filing)

A flat toll, not a commission

The charge does not scale with the size of the trade. Whether the contract covers a small or a large amount of the underlying thing, the toll per contract is the same published average.

That is the opposite of how most financial charges work. A charge set as a share of the value grows when the value grows, while a flat toll only grows when the count grows.

So the whole business rests on traffic rather than on value. The published average day of 29.4 million contracts is the number that matters, and the toll of $0.679 is almost an afterthought by comparison.

The data business works on a different principle again. Prices are a by-product of running the exchange, they cost almost nothing extra to supply, and they are licensed rather than charged per contract.

The actual math on a flat toll

Two published figures multiply together. An average day of 29.4 million contracts at an average of $0.679 each comes to about $19.96 million, or roughly $20 million of toll revenue a day. That is an average built from two averages, not a record of any particular day.

Hold that next to the quarter's total. The toll line was $1,378.1 million of $1,737.3 million of revenue, which is 79.3 percent of everything the business took in.

The data line was $243.1 million, or 14.0 percent, and the remainder was $116.1 million, or 6.7 percent. Those three add to the printed total exactly.

Now the growth rates, which point the other way. The toll line rose 12.2 percent against the same quarter last year while the data line rose 20.0 percent, so the smaller business is the faster one.

What this means

When you want to know how a marketplace earns, find out what it charges per unit and how many units pass through. A number too small to notice can become a large business on volume alone.

The second thing to look for is the by-product. Running any marketplace generates a record of what happened, and that record can be worth selling separately from the activity that created it.

And the growth rates are worth reading next to the sizes. The biggest line here is not the fastest, which is a different picture of the business from the one the headline revenue gives.

What this is NOT

This article explains how a contracts marketplace charges for access and where its revenue comes from, using CME Group Inc.'s third quarter 2026 results furnished as exhibit 99.1 to a Form 8-K filed October 21, 2026, accession number 0001156375-26-000065, read on October 21, 2026. It is not investment advice and it is not a recommendation to buy, hold, sell or avoid any security, including this company's. It is not advice to trade anything: futures and other contracts can lose more than the amount put up, this article explains none of that risk, and nothing here suggests that trading them suits anyone. It does not explain what a futures contract is, how one is priced, how to open an account, or what any charge would be for an individual, because a published average across all products is not anyone's actual cost. It is not a comparison with any other marketplace, exchange or broker, none of which it examines. It makes no claim about whether the charges are high or low, fair or unfair. The only arithmetic here is multiplying and dividing figures the filing itself publishes, and every result is stated alongside the printed figures it came from; the daily figure is an average built from two averages and is not a record of any actual day. It quotes no person and names no officer or executive. This is not a political endorsement or criticism of anyone.
