The exchange is not the app
A sportsbook owns its customer: the account, the app, the promotions, the relationship. An exchange is infrastructure, and the fastest-growing prediction markets have reached most of their customers through somebody else's app. Understanding the distribution layer is understanding why the product grew faster than any licensed sports betting launch, and why the partners it signed are the ones that decide its future.
Brokerages
The largest single channel for regulated event contracts in the United States is retail brokerages. A customer who already has a share-dealing app, an identity verified against financial rules and a funded account can trade an event contract in the same interface as a stock, with no new sign-up, no gambling-specific verification and no sense of having entered a betting product. The brokerage routes the order to the designated exchange, takes a share of the fee and reports the trade as it would any derivative.
For the exchange this is the whole game: tens of millions of verified, funded adults reachable without acquiring them. For the brokerage it is a new revenue line with very high engagement, because a contract on tonight's game is traded more often than an index fund. For a gambling regulator it is the model's most provocative feature. A state that has decided its residents may not bet on sport finds them doing so through a stockbroker, at 18, and the brokerage's answer is that it is offering a federally regulated financial product.
Brokerages have not been uniform. Some have offered sports contracts nationally; some have withdrawn them from states where litigation is unfavourable; some have listed only economic and political markets. Those decisions track the legal map in lesson three, and a brokerage's risk appetite is now a variable in the industry's competitive analysis.
Crypto exchanges and wallets
The crypto-native venues distribute through the crypto ecosystem: wallets, exchanges, aggregators and the blockchain itself, on which anyone can build an interface to the same contracts. This is what "non-custodial" means in practice. The venue does not hold the customer's funds or, in the purest form, know who the customer is; it publishes a market and the trades settle on-chain.
That architecture is why the crypto-native venues have been blocked rather than licensed in most of the world. A gambling regulator can order internet providers to block a domain and can pursue the customers, as Korea has, but it cannot revoke a licence the venue never held or fine an entity it cannot serve. The venues' answer to the American market has been to acquire a designated exchange and run a compliant, custodial, identity-verified product alongside the global one, which is an admission that the architecture and the licence are alternatives, not complements.
Sportsbooks and casinos
The licensed operators arrived last and may matter most. By late 2025 the largest American sportsbooks had each chosen a route into the product: applying for exchange designation in their own right, buying an existing designated exchange, or partnering with one to distribute contracts through their sportsbook app. The strategic logic was covered in lesson five. The distribution logic is simpler: a sportsbook has millions of verified betting customers, a brand, a marketing budget and, in states without legal betting, nothing to sell them until now.
An operator distributing exchange contracts through its app has to decide what the customer sees. One screen with odds and contracts side by side, or two products under one brand, or a contract offer only in states where the sportsbook is not licensed. Each choice has a regulatory reading. A licensed sportsbook offering unlicensed contracts to customers in its own licensed state invites its regulator's attention; offering them only in states where it holds no licence is the model most operators chose, and it is one the states are watching closely.
Casinos and tribal operators face a harder version. A tribe with compact exclusivity sees an exchange as a competitor it cannot match on terms; the class III ruling described in lesson three is its defence. Some tribes have nonetheless explored offering contracts themselves, on the reasoning that a product they cannot stop is better owned than fought.
Media, data and leagues
Sports leagues and their data companies signed with the exchanges quickly, for the same reason they signed with sportsbooks a few years earlier: a venue that trades on their games is a customer for their data and a partner for their content, and a league inside the tent has more say over integrity than a league outside it. Broadcasters have integrated exchange prices into coverage, and the prices are quoted in political and financial media as forecasts, which is marketing no sportsbook has ever been given for free.
The media channel has a regulatory edge. Advertising sports betting is restricted in most legal states and prohibited in states without it; a broadcaster showing "the market's probability" on screen is doing something the same states have not decided how to treat. Affiliates, the performance-marketing channel that drives much of licensed sportsbook acquisition, have moved into exchange promotion for the same reason, and the affiliate compliance frameworks in the Marketing Compliance course do not yet have a category for it.
International distribution
Outside the United States the regulated exchanges have little presence, because a designated contract market's designation means nothing to a gambling regulator in Europe or Asia, and the crypto-native venues are blocked where regulators have acted. The licensed betting exchanges in Britain and elsewhere are the local equivalent and have existed for two decades under gambling licences. The international question for an exchange is therefore whether to seek gambling licences market by market, as the betting exchanges did, or to stay with the crypto architecture and accept the blocks. Both are being tried.
For an operator outside the United States, the practical question is different: whether to launch an exchange-style product under an existing licence. Several have. The economics of a peer-to-peer book inside a licensed operator are the economics of a betting exchange, which are well understood, and the political advantage of offering the product within the licensed system rather than watching it arrive from outside is obvious to regulators who have spent two years reading American court filings.
What a partnership decides
A distribution partnership with an exchange settles four things, and each is worth negotiating rather than accepting.
Liquidity. Whether the partner's flow goes into the exchange's central book or a segregated one. A shared book gives the partner's customers better prices and gives the exchange the partner's liquidity; a segregated book keeps the partner's data private and its prices worse.
Identity and compliance. Who verifies the customer, to which standard, and who is responsible when a state regulator asks. The partner's licensed status does not transfer to the exchange, and a state may treat the partner as the one offering the product.
Economics. The fee split, the market-maker arrangements and whether the partner is permitted to hedge its sportsbook liabilities on the exchange, which is the most valuable right in the agreement for an operator with a book.
Exit. What happens if the law changes. Every agreement signed since 2025 has a clause about the litigation, and an operator that cannot exit cleanly when a state wins has taken on a risk the exchange does not share.
What to take from this lesson
Exchanges grew through other people's apps: brokerages first, then sportsbooks, with leagues and media supplying credibility and reach. Distribution is where the regulatory exposure now sits, because the partner is the entity a state can reach. A partnership with an exchange is a decision about liquidity, identity, economics and exit, and the last of those is the one most likely to be tested.
