Are prediction markets legal? Check the entity and your location
Legality depends on the entity, contract, user location and access route; registration or a visible app does not establish worldwide permission.
There is no single worldwide answer
Prediction-market legality depends on the location, legal entity, contract and access route involved. A market being visible online does not establish that you may trade it. A platform's registration in one country also does not authorise every product or every user worldwide. Begin with your actual location and the specific service, not a general statement about the category.
Separate three questions: whether the venue is authorised, whether the particular contract is permitted, and whether you meet the account's eligibility conditions. The answers can differ. A read-only probability dashboard, a play-money community and a cash event-contract exchange are not automatically subject to identical rules.
This guide is general information, not legal advice. For mechanics, read how prediction markets work. For a category-based overview, use the prediction-market list. Neither list membership nor a familiar app logo substitutes for current regulatory verification.
The United States: registration and disputes are separate
The CFTC maintains a register of designated contract markets. That is an authoritative place to check the named entity and status. “Pending” is not the same as “Designated,” and an entity's trading name may differ from the brand in a search result.
The Congressional Research Service's March 2026 overview describes event contracts and the expansion of consumer-facing markets. It also discusses litigation over sports-specific markets and the relationship between federal derivatives oversight, state gambling law and tribal gaming law. That makes blanket claims such as “every sports contract is legal in every state” inappropriate.
Use the current register, applicable product documentation and relevant current legal information. A historical article can accurately describe a court decision at publication while failing to explain the present position after later proceedings. Registration is an important fact, but it is not a complete personal eligibility analysis.
Kalshi and Polymarket US require entity-level checks
Kalshi is discussed in the CRS material as a CFTC-regulated exchange. That does not mean the regulator guarantees a contract's return, approves a trader's strategy, or removes all jurisdictional disputes affecting a particular product.
The CFTC register identifies QCX LLC doing business as Polymarket US. The international Polymarket service has its own geographic restrictions and documentation. Do not transfer an access statement from one to the other simply because both use the Polymarket name.
If using an intermediary app, identify the underlying venue and the entity holding the account or executing orders. A convenient front end can distribute access to another firm's exchange. Its branding does not change the contract, venue rules or location restrictions.
A verification table
| Check | Evidence to seek | Common mistaken shortcut |
|---|---|---|
| Entity | Regulator's current register and legal name | Recognising the brand |
| Product | Current contract and product rules | Assuming all event categories are equivalent |
| User eligibility | Location, age, identity and account conditions | An app accepting an email address |
| Access route | Official service and permitted intermediary | A third-party bot saying it works |
| Current restrictions | Platform checks and applicable current guidance | An old “all states” headline |
Save a dated record of the sources used for a consequential decision. If the answer remains unclear, seek qualified guidance before funding the account. The cost of waiting is preferable to treating ambiguity as permission.
The international platform's geoblocking
Polymarket's official documentation says order placement is restricted from certain locations for regulatory and sanctions-compliance reasons. It provides a geographic-eligibility check and says orders submitted from blocked regions will be rejected.
That is a clear boundary for users and software builders. An analytics tool may read public market information while trading is unavailable. Do not treat a successful data request as proof that placing orders is permitted.
Do not bypass geographic restrictions with VPNs, false residency details or borrowed accounts. Apart from legal and contractual concerns, workarounds can complicate withdrawals, identity checks and disputes. A third-party tool's ability to send a request does not establish your right to use it.
Great Britain, Australia and Uganda
In Great Britain, consult the Gambling Commission where the product falls within gambling regulation and identify the actual operator and permissions. Do not assume an offshore event market is covered by another service's licence. If the classification is unclear, the term prediction market does not resolve it.
In Australia, ACMA's Interactive Gambling Act guidance explains restrictions on online gambling services, including online in-play sports betting. A service's offshore event-contract label should not be treated as an automatic exemption from the rules relevant to the actual product.
In Uganda, the NLGRB's current licensed-company publications are a starting point for verifying gambling operators. A brand's international presence or mobile-money compatibility is not evidence that it holds the necessary local permission. A directory entry for a bookmaker also does not establish approval for an unrelated prediction-market venue.
These are verification starting points, not definitive classifications of every possible contract. The relevant service, legal structure and local rules must be assessed together. Do not infer a prohibition or permission solely from the absence of a brand on a casually searched page.
Play money and prizes need separate analysis
Manifold's About page describes mana as play money that cannot be converted to cash. It also describes separate prize-related features. Those should not be combined into a blanket claim that mana trading is cash betting or that every user can redeem balances.
A non-redeemable play-money market differs economically from a cash event contract. A separate drawing, prize or promotional programme can introduce its own eligibility and terms. Read those terms rather than extending the main site's general description.
Likewise, a forecasting tournament may reward skill without offering tradable contracts. Similar interfaces can hide different legal and economic products. Define the feature you intend to use before applying advice about another category.
Financial risk remains after eligibility
Legal availability does not make a contract a good purchase. If a one-unit payout contract costs 0.70 and resolves against you, the purchase cost can be lost. Selling before resolution requires a counterparty and may produce a worse price.
Fees, spreads, funding costs, thin liquidity and ambiguous resolution terms are separate risks. Kalshi publishes a fee schedule with product-specific provisions; Polymarket describes fees for certain markets. Do not use one general marketing statement to infer a universal cost structure.
The software guide explains permission boundaries and execution failures. The apps guide covers publisher and download checks. Neither engineering quality nor official distribution changes the legal analysis of your account.
Records, taxes and disputes
Maintain contract identifiers, transaction records, fees, deposits, withdrawals and the resolution terms relevant to your positions. Keep the currency and valuation method explicit, particularly where blockchain assets or cross-border transfers are involved.
Tax treatment depends on your circumstances and applicable law. A platform's status does not establish that your gains are tax free or that every loss is deductible. Seek local tax advice when needed rather than relying on a social-media summary.
For disputes, use the venue's published process and identify any applicable regulator or adjudication route. Do not assume protections associated with a bank deposit, sportsbook account or securities account automatically apply to a different product. Read the actual custody and customer-protection disclosures.
A decision sequence before funding
Identify your physical location and the precise entity. Check its current status, the product and your eligibility. Read geographic restrictions, identity requirements, contract terms, funding rules and withdrawal conditions. Understand fees and the maximum affordable loss.
If a material answer is missing, pause. Do not complete the gaps with a referral site's assurance, a popular app-store ranking or an old court headline. Recheck after major rule or product changes, because a correct past observation can become stale.
The goal is not to declare every prediction market legal or illegal. It is to make the claim narrow enough that evidence can support it: this entity, this product, this user location and this date.

Frequently asked questions
Are prediction markets legal in the US?
Some venues operate within federal event-contract regulation, but the specific entity, contract, location and current disputes matter. Check the CFTC register and applicable current rules. A general statement about prediction markets is not enough to establish access to every sports or political contract.
Does CFTC registration guarantee a safe investment?
No. Registration concerns regulatory status, not a guaranteed return or the accuracy of market prices. Contracts can lose their purchase value, liquidity can be limited and fees can matter. Read the relevant customer-protection and custody disclosures rather than assuming bank-like guarantees.
Can I use a VPN where a platform is blocked?
Do not use location spoofing or false account details to evade restrictions. Polymarket's documentation explicitly describes geographic checks and rejection of orders from blocked regions. Public data availability does not establish eligibility to trade.
Are play-money prediction markets treated the same way?
Not automatically. Non-redeemable play money, cash contracts and separate prize programmes differ. Manifold describes mana as non-convertible, while other features have their own terms. Evaluate the specific activity and jurisdiction rather than relying on a broad platform label.
Is legality the same as tax treatment?
No. Access, regulatory status and tax obligations are separate questions. Keep complete transaction and fee records and obtain appropriate local advice. A legal service does not automatically make gains tax free or establish how losses should be reported.
