The venue's real risk
An exchange carries no liability on outcomes, so its risk is not that the favourite wins. Its risk is that a contract resolves wrongly, that a price is manipulated, or that someone trades on information the market did not have. Each of those is a failure a sportsbook also faces, but the exchange faces them differently, because it is a marketplace whose only asset is trust in the marketplace.
This lesson takes the three in turn and then adds the one that is new: a prediction market can be a market on something the traders themselves can influence.
Resolution
Every contract carries a rule stating what source will be consulted and what counts as yes. The quality of the rule is the quality of the product.
Sport is easy. The final score from the league's official record is unambiguous, and the only questions are the ones bookmakers already handle: postponements, abandoned games, overturned results. Exchanges borrow the sportsbook's settlement rules for these cases, and a customer who has read a bookmaker's terms will recognise them.
Economics is medium. A contract on an inflation print resolves on a published statistic, but the statistic gets revised, the release can be delayed and the contract must say which version counts. Exchanges have learned to specify the first release, the exact series and the time of resolution.
Politics and world events are hard. "Will X be confirmed by the Senate" is fine. "Will there be a ceasefire" is not, because the world does not always produce a clean fact. The regulated exchanges resolve through a committee under published criteria with an appeal, and the exchanges publish the outcomes and reasoning. The crypto-native venues resolve through an oracle: a process in which holders of a token vote on what happened, with financial incentives to vote with the majority. That design has been exploited. A well-capitalised participant who holds a large position in a contract and a large share of the voting token can, in a contested case, vote for the outcome that pays them, and there have been resolutions where the market's own users concluded that is what happened.
For a gambling professional the lesson is that resolution is a governance question, not a data question. A sportsbook's settlement is a decision the operator takes and stands behind; an exchange's resolution is a decision that has to be seen to be independent of anyone who traded. The contract drafting, the source hierarchy and the dispute process are where an exchange either earns trust or loses it, one contested market at a time.
Price manipulation
Manipulating a price on an exchange means trading in a way designed to move the price away from where information would put it. The techniques are the ones securities regulators have chased for a century.
Painting the tape. Placing trades to create the impression of activity or a trend, often by trading with oneself through multiple accounts. On a thin market, a few thousand dollars can move a contract twenty cents, and the moved price then gets quoted by the press as "the market's view".
Spoofing. Posting large orders with no intention of filling them, to induce others to trade, then cancelling. Regulated exchanges surveil for it because the act requires them to; crypto-native venues have less visibility.
Motivated manipulation. The distinctive case. On a market about an election, a policy decision or a corporate announcement, a participant may want the price to show a particular probability, because the price itself is being reported and influences opinion. The 2024 presidential election produced the textbook example: a single trader's very large positions moved one candidate's price well above the polls for weeks, and whether that was a view or a message was debated in public. The trader was, in the end, right, which illustrates the confirmation trap covered in the Sports Integrity course: a winning position is not evidence of manipulation and a losing one is not evidence of innocence.
A regulated exchange's answer is the toolkit of any exchange: surveillance, position limits on contracts where a single participant could dominate, and the power to void trades and bar accounts. The strength of those tools depends on the venue being able to identify its customers, which is the point at which the regulated and the crypto-native models diverge most.
Insider trading
A prediction market on a corporate announcement, a court ruling or a government decision is a market on which some people know the answer before others. Trading on that knowledge is the central integrity risk of the product, and it is one that the regulated venues, the crypto-native venues and the gambling regulators all agree is a problem, even if they disagree about whose problem it is.
Several public cases established the pattern in 2025 and 2026. Accounts opened shortly before an announcement, taking large one-sided positions on an outcome that then occurred, traced to people who were in a position to know. Some were referred to prosecutors under securities and commodities law; some resulted in voided markets and banned accounts; some were never resolved because the venue could not identify the account. The signals are the ones that the Sports Integrity course teaches for suspicious betting: new accounts, concentrated timing, positions out of proportion to the account's history, and an outcome that confirms.
Two features make the risk worse than in sports betting. First, the universe of events on which someone has inside knowledge is far larger than the universe of games. Every corporate action, regulatory decision, award, product launch and political appointment is a potential market, and every one has insiders. Second, the regulated venues' legal position, that their contracts are federal derivatives, means insider trading on them is a federal offence with serious penalties, which is a stronger deterrent than a gambling regulator's fine but also a reputational exposure the venue has to manage in public.
The sports overlap
A contract on a game is a bet on a game, whatever the courts eventually call it, and the integrity risks of sports betting arrive with it. A fixed match pays on an exchange as it pays at a bookmaker. A courtsider trades an in-play contract before the price updates. An athlete trading a contract on their own team is insider betting in the sport's rulebook, whatever it is in the exchange's.
The difference is institutional. Licensed sportsbooks in most markets are required to report suspicious betting to the regulator and to the sport, they belong to integrity associations that pool alerts, and they work with monitoring companies. Exchanges have been slower to join those structures, partly because they argue they are not sportsbooks, partly because their customer identification is weaker, and partly because the professional flow they welcome looks, to a monitoring model, exactly like the flow a bookmaker would flag. The largest exchanges have begun signing data and integrity agreements with leagues and monitoring firms, and a league that sells data to an exchange has an interest in seeing its markets policed. A professional in a trading or integrity role should expect to be handling exchange-sourced alerts within a few years, and should expect them to be harder to read.
Markets the traders can move
The genuinely novel risk is a market whose outcome a participant can influence. A contract on whether a bill passes, traded by a legislator's staff. A contract on whether a company announces layoffs, traded by the company's management. A contract on whether a protest reaches a certain size, traded by its organisers. The academic literature calls these manipulable markets, and it has always recognised them as the boundary of what a prediction market should list.
The regulated exchanges answer with contract selection: they do not list markets that a small group controls, and the CFTC's gaming and public interest provision gives it a power to prohibit contracts that cross the line. The crypto-native venues have listed almost anything with demand and have relied on the oracle to sort out the consequences. Between those two positions is where a gambling regulator's instinct, that a market on an event one participant controls is an invitation to fix it, has the most to offer the debate.
What to take from this lesson
An exchange's integrity risks are resolution, manipulation, insider trading and manipulable events. The first is governance; the second is surveillance; the third is the largest and shares its signals with suspicious-betting detection; the fourth is a listing decision. Customer identification underlies all of them, and it is the dimension on which the regulated and crypto-native models differ most. The tools are the ones exchanges and sportsbooks already have; the work is applying them to a product that lists events nobody has monitored before.
