Prediction Markets: Why Operators Need More Than a Sportsbook Strategy

Gambling businesses often expand into an audience they already understand. A bookmaker with loyal customers may see another sports-related product as a natural next step. The idea looks simple, especially when an existing brand can support it.

But prediction markets deserve a closer look before operators act on that plan. Familiar sports coverage can hide real differences in how the product should work. Choosing which events to offer needs careful legal review, and the method used to settle a result needs its own checks.

Operators need to understand exactly what they would be offering in each country. Even experienced businesses face this challenge when they try to adapt an existing setup for a new territory. A good starting point combines commercial interest with a clear view of the responsibilities involved.

Trading Boom in Online Gambling

An event contract pays out based on whether something specific happens — for example, a football result or a change in an economic indicator. Participants buy and sell these contracts on an exchange.

By mid-2026, the sector had reached a substantial scale. Combined monthly activity on Kalshi and international Polymarket rose from under $5 billion in September 2025 to about $24 billion in April 2026. These figures use a measure called notional taker volume, which counts each contract at its $1 potential payout. Actual purchase prices can be lower, and operator revenue is a separate question.

Sport carries different weights on each platform. From July 2024 to early May 2026, it made up 80% of Kalshi’s total turnover but only 39% of international Polymarket’s. So a jurisdiction that restricts match-related activity would affect the two platforms very differently.

Geography matters just as much. In April 2026, the US version of Polymarket generated roughly $1.3 billion in trading volume, versus about $9 billion overseas. Treating both operations as one commercial picture can hide the fact that they sit under separate regulations.

For a new entrant, these numbers show the size of the opportunity. But they don't answer which part of it a given business can legally serve. A large international audience is worth little to a launch plan if its most popular categories aren't allowed.

This is where a sportsbook-only view falls short. Experience with major competitions is a useful foundation, but expansion needs a closer look at exactly what is being offered.

Betting and Event Trading: Meeting Point

DraftKings introduced its proprietary exchange, DKeX, in June 2026 and built it into the company’s combined app. Customers can see sportsbook products alongside prediction contracts, with availability depending on their location. So one shared interface now brings two separate forms of betting together.

The lesson here is about how the offer is organised. An established brand gives customers a familiar entry point, but the rules behind each category stay separate. For a new operator, that makes the link between the front end and local permissions especially important.

Official sports partnerships add another layer. MLB’s agreement with Polymarket gave access to league branding and data supplied through Sportradar. It excluded sensitive events such as individual pitches or managerial decisions. A separate arrangement with the CFTC covered information sharing on baseball integrity.

The real impact is on product selection. Anyone considering a similar deal should check the allowed customer offer alongside the commercial rights. Those conditions decide how much value the partnership actually delivers.

FIFA added further visibility through its World Cup 2026 partnership with ADI Predictstreet, which created a dedicated sponsorship category for prediction markets. But commercial partners still need to check local authorisation before using such deals to promote a real-money service.

Together, these examples show why international exposure needs country-by-country planning. A well-known partnership can attract attention, but the campaign still needs a lawful destination for its audience. The business case should reflect where those visitors can actually use the advertised service.

Local Rules and Offer Creation

The same technology can support activities that fall under different legal classifications. For an operator, the event behind each contract becomes part of the initial review. Decisions about launch geography should therefore come before the final list of offers.

How that choice affects the available range:

Brazil and a Boundary around Financial Events

Resolution CMN 5.298/2026 excludes match results and political outcomes from the allowed derivatives framework. The rules also cover relevant overseas instruments offered to Brazilian customers.

Allowed reference points include interest rates or currency movements, as long as the relevant requirements are met. For a betting business, this distinction changes what the product actually is. Wrapping a match-based offer in a financial structure alone does not make it eligible under this route.

Canada and Access through an Approved Range

CIRO’s March 2026 framework let two investment dealers offer a limited selection of event contracts. The approved categories cover economic and financial indicators, plus environmental forecasts, and each contract must run for at least 30 days. Political outcomes are excluded, and clients cannot trade on borrowed money.

A wider catalogue needs a separate business-change application. This tells newcomers that approval for one activity has clear limits — any expansion beyond those terms needs a new review.

The EU and Importance of National Differences

Classification depends on the subject and the features of the instrument. Financial contracts that pay out a fixed amount or nothing at expiry can fall under binary-option rules, which often ban sales to retail customers. National gambling law can also apply to event-based offers.

For an international launch, both layers matter. A favourable ruling in one country says little about what customers in another country can access.

Gibraltar and a Dedicated Licensing Route

The Prediction Market Regulations 2026 were introduced under the territory’s Gambling Act 2025. This framework sets out a dedicated route for authorising the activity.

What matters here is that a route exists that is built specifically for this format. Businesses considering it still need to work out the conditions attached to their own operation. And a licence in Gibraltar still leaves open the question of lawful access elsewhere.

The US and Competing Claims to Authority

Federal oversight has run into challenges from state gambling laws. In April 2026, the CFTC filed lawsuits against several states, which were trying to apply local restrictions to registered exchanges. The dispute is over which level of government controls these contracts, especially around sport.

A launch plan should account for the relevant rulings in each state. Treating federal registration as the full answer would leave an important part of the review unfinished.

Distribution as a Business Barrier

A platform can lose contact with customers in several ways. Enforcement can hit mobile access as well as the website itself. Marketing teams need a clear picture of where their campaigns can actually run.

Recent measures and blocked channels:

• website restriction in Spain during proceedings involving Polymarket and Kalshi;
• internet-provider restrictions in France after earlier geographical controls proved insufficient;
• app removal or access limits ordered for Google and Apple in Argentina;
• investigation of affiliated social-media accounts for possible restrictions in Indonesia.

The consequences can reach promotional material too. French rules allow penalties of up to €100,000 for advertising unauthorised gambling services or publishing odds for that purpose. That risk makes legal review of a campaign necessary even before a single visitor tries to take part.

Staying available after an enforcement order can carry a direct cost too. The Dutch regulator moved to collect a €420,000 penalty from Polymarket’s operating company after it breached an earlier order. This shows why a notice needs a real operational response, with someone clearly responsible for acting on it.

For an expanding business, the key task is matching acquisition plans to the offer it can lawfully deliver. Spending on traffic before settling this question risks building a campaign that leads nowhere. The review should cover the whole customer journey, including access through third-party services.

Outcome Integrity and Manipulation Risk

A wider catalogue brings subjects with different risks of unfair advantage. One participant may have private knowledge; another may control what actually happens. And settlement — deciding the final result — depends on having reliable evidence.

The main weaknesses:

Early Access to Private Information

In April 2026, the CFTC brought an insider-trading case against US service member Gannon Ken Van Dyke. He was accused of using classified knowledge of the operation targeting Nicolás Maduro, with suspected profits of over $404,000.

A separate proceeding involved Google engineer Michele Spagnuolo and confidential company data. The alleged scheme made about $1.2 million from positions tied to unpublished information — allegations still to be proven in court.

For operators, both cases show why monitoring must follow the subject of the contract. A company announcement can give an unfair edge to employees who see it before release. Government-linked outcomes raise the same concern about access to official information.

Direct Influence over an Event

The George Santos case involved a bet on his own attendance at the State of the Union. In a July 2026 settlement with the CFTC, he agreed to repay his profits and pay a civil penalty, without admitting any findings, plus a three-year trading ban.

The bigger issue is whether a participant can control the very outcome the contract pays on. Wildfire-based contracts raise a similar concern — a financial incentive for arson — which drew a Senate intervention in August 2026.

Vulnerable Sources of Evidence

Unusual temperature readings at Paris Charles de Gaulle Airport raised suspicions of tampering with weather equipment in April 2026. Polymarket positions tied to that location depended on those readings. The incident led to a police complaint, and who was behind the suspected tampering still needs to be investigated.

For a provider, the lesson is about the reliability of the final data source. Even a clear question can produce a disputed payout if the underlying record is compromised. External data feeds deserve as much scrutiny as participant behaviour.

Viable Expansion Plan

Operators need a sequence that turns commercial interest into a workable plan. Start with the intended audience, then work out the conditions under which the business could actually serve it.

A relevant assessment can follow the key steps:

1. Choose the destination. Get a jurisdiction-specific review before you commit to a launch date. Identify the permission route that fits the activity and confirm any restrictions on customer access.
2. Define the eligible catalogue. Separate acceptable subjects from ones that need more review. Build the initial offer around categories with a clear legal basis, and leave unresolved additions out of the launch.
3. Check how results will be established. Examine the chosen evidence source and any chance of manipulation. Decide whether the outcome can be verified reliably before offering it to customers.
4. Review the route to the audience. Check promotional plans alongside distribution rules. Make it clear which team is responsible for responding to restrictions, across both acquisition and account handling.
5. Plan for local configuration. Where allowed, keep the shared technology and adapt the offer for each territory. Plan expansion around what can actually be delivered there, and what that requires operationally.

This sequence gives a basis for comparing realistic opportunities. It also stops spending from running ahead of unresolved eligibility questions. For smaller teams, a clearly defined starting scope makes the work easier to manage.

For example, one technical system can support operations in several countries where the law allows it. But its catalogue must still match what's authorised in each destination. So the operator needs to be able to apply a local restriction quickly, and adjust the related promotional material at the same time.

The Main Things about Prediction Markets

Event-based exchanges have become commercially significant, with direct links to established iGaming businesses. Their growth also shows how much a launch depends on which subjects are available to customers. A good strategy connects that opportunity with the conditions needed to operate responsibly.

Key aspects about prediction markets for operators:

• Headline transaction figures show activity, but the real business case depends on which categories are allowed in the target jurisdiction.
• Financial classification can bring its own restrictions, so the legal review must look at what the product actually is.
• International sports partnerships bring visibility, but local permission decides where the linked service can actually reach customers.
• Reliable outcomes depend on guarding against unfair participation and trusting the evidence used for settlement.
• Shared infrastructure can support expansion, as long as country-specific controls shape the offer each audience receives.

The strongest starting point is a clear understanding of what the company can actually deliver in its chosen territory. Sportsbook experience helps with that work, but broader checks make the plan complete.
