The question is not which market has better odds. It is which rails let you get paid when you are right — and by whom.
When a new user types "prediction markets" into a search engine, the results will surface Polymarket and Kalshi in the same breath. That creates a widespread misconception: that these are two flavours of the same product. They are not. The rails are structurally different, and the difference matters before your first deposit, not after.
What "regulated" actually means
A US CFTC designated contract market (DCM) is not just a label of trustworthiness. It is a specific legal product classification. Kalshi and ForecastEx hold DCM status, which means their event contracts are classified under the Commodity Exchange Act, their resolution disputes have a regulatory reference point, and eligible users trade through a structure that has passed federal review. That review has limits — it does not guarantee any individual outcome, and state-level availability can still vary — but the legal infrastructure is present.
Polymarket is a crypto-native venue. It uses smart contracts on Polygon, settles via USDC, and treats geo-policy as a product layer rather than a regulatory gate. For users outside restricted jurisdictions, this can mean faster access and a wider event catalogue. For users inside restricted jurisdictions — particularly US persons — it often means a hard stop at onboarding. The wallet is the custodian, not an account-holding regulated entity.
Why the spread looks the same but is not
A contract priced at 0.55 on Kalshi and a market priced at 55¢ on Polymarket may look identical in a screenshot. They are not equivalent positions. The settlement path, the resolution arbiter, the dispute mechanism, and the fund-recovery route are all different. On a CFTC DCM, the exchange resolves according to its published contract specifications, and disputes have a regulatory address. On a crypto venue, resolution follows the oracle and the smart contract terms — which can be correct, but which have no equivalent federal escalation path when they are wrong.
The practical comparison
Neither model is universally better. Regulated rails suit users who need a clear legal structure and are willing to pass KYC. Crypto rails suit users who prioritise access, speed and a broader event catalogue, and who understand wallet custody. The comparison job is not "which has better markets" but "which rails match my region, custody tolerance and risk posture." Start with the USA ranking or the How to start guide — not with a market discovery screenshot.
A wallet is not a safe. It is a key. What the key opens, and under whose rules, is the part most first-time users skip reading.
The prediction market industry uses the word "custody" to mean several different things depending on where you look. A CFTC DCM holds client funds in a regulated account. A crypto-native venue holds funds in a smart contract or protocol treasury. A play-money platform holds nothing, because nothing real is at stake. Treating these three as variants of the same model is how users end up surprised when things go wrong.
Account custody: the regulated model
On a regulated venue like Kalshi, you open an account, pass KYC, and deposit fiat. The venue holds those funds in a structure subject to CFTC oversight. You trade event contracts, and your balance reflects open positions and settled outcomes. The risk here is not that your funds will disappear without notice — the legal structure prevents that in most normal scenarios. The real risk is resolution: if a contract settles differently than you expected because the resolution criteria were worded in an unexpected way, that outcome is final under the contract rules.
Wallet custody: the crypto model
On Polymarket, Azuro or SX Bet, you connect a wallet. The wallet holds your tokens — typically USDC or a native chain token. When you place a market position, the tokens move to a smart contract. You are not giving a company your money in the traditional sense; you are interacting with code. That is both the appeal and the risk. If the smart contract has a bug, if the oracle is manipulated, if the chain experiences an outage at resolution, the code executes its logic — not what you expected the logic to say. There is no customer support line that can reverse a confirmed blockchain transaction.
What "no KYC" actually transfers to you
Lower friction at onboarding does not reduce risk — it transfers more of it to the user. When there is no KYC, there is also no account recovery. A lost seed phrase is a lost balance, permanently. A wrong-chain deposit is typically unrecoverable without direct platform support, which may not exist at the speed or depth you need. The No-KYC list on GammaPredict carries watchlist warnings precisely because the custody profile is different, not because no-KYC is inherently dishonest.
The custody checklist before any deposit
Before funding any position: identify who holds the funds (account or contract), identify the resolution source and who arbitrates disputes, understand the withdrawal path and timeframe, and test with a small amount before any meaningful size. The fees comparison page covers explicit costs; custody risk sits underneath all of them.
The probability on an election market is not a poll. It is the market's current best guess at the probability of a specific, contractually defined outcome — which may not match the outcome you are thinking about.
Election markets are the most visible corner of prediction markets during a campaign cycle, and the most misread. A price of 0.72 does not mean the candidate is 72% likely to win in a general sense. It means the current market participants are implying a 72% probability of the specific resolution criteria defined in that contract being met. The difference matters enormously when the contract language does not match your intuitive read of "winning."
Resolution criteria: the most important thing most users skip
Every election contract on Kalshi, Polymarket, PredictIt or any comparable venue specifies a resolution source and a resolution condition. That condition is almost always more specific than "the winner of the election." It might resolve on the certified result of a specific state, on the Electoral College final tally, on who is inaugurated — not necessarily who leads exit polls on election night. A contract that resolves on inauguration and a contract that resolves on the certified popular vote are two different bets, even if they look like the same market on the surface.
Read the market description before any position. The resolution source — which could be the Associated Press, Reuters, or the official canvass — determines when and how your contract settles. Delays in certification, recounts, or legal challenges can extend a contract's open period beyond election night. On a crypto-native venue, the oracle that feeds the resolution data is a third layer of potential divergence from your expectation.
Liquidity and the late-shift problem
Election markets tend to see their highest liquidity in the final days before a result, which is also when prices move fastest. A market at 0.60 two months out might reach 0.90 on election eve if the race shifts strongly. That move is the market repricing the probability — not necessarily you "winning" your position. If you entered at 0.60 and want to exit at 0.88 rather than waiting for resolution, you need a liquid exit. Thin books mean wide spreads, which means the exit cost may erase a significant portion of your notional gain.
Who should use election markets
Users who understand resolution criteria and can hold through resolution. Users who have checked access — Kalshi is available to eligible US users; Polymarket access for US persons is often restricted; PredictIt operates under specific federal exemptions with position caps. A price on an election market is information, not an instruction. The political betting sites comparison explains the access split by venue.
There is no global prediction market. There are regional markets with different legal classifications, different product types, and different enforcement postures — all accessible from the same browser.
The phrase "prediction markets are global" describes their technical accessibility, not their legal status. A resident of California, someone in Germany and a user in Singapore can all load the same interface. What they can legally or contractually use on that interface is three different answers — and treating them as one is the fastest path to a blocked account or an unenforceable claim.
The US path: CFTC designated contract markets
The US regulatory framework for event contracts runs through the Commodity Futures Trading Commission. Confirm current DCMs on CFTC DCM filings. A CFTC DCM is the clearest regulated research path for eligible US users. Currently GammaPredict lists two: Kalshi as the broader event-contract start, and ForecastEx as the second DCM on the shortlist. Both require KYC. Both operate under contract specifications that define resolution exactly. State-level access can still vary — always confirm eligibility with the platform before depositing, not with a screenshot of the signup screen.
PredictIt occupies a separate space: a no-action letter from the CFTC for educational research markets, with position caps that limit exposure per contract. It is a politics specialist, not a general event-contract venue. See Kalshi vs PredictIt for the side-by-side.
The UK path: UKGC licences
The UK Gambling Commission licences betting exchanges — confirm names on the UK Gambling Commission public register. Smarkets is the primary UKGC-licensed venue on GammaPredict's flagship list for UK users. Kalshi's US CFTC licence does not carry to the UK — that is a common misconception. A UK user researching "Kalshi alternatives" is looking at a different regulatory universe than a US user asking the same question. The UK ranking separates these intentionally.
The crypto space between
Crypto-native venues like Polymarket, Azuro and SX Bet operate in a space that is neither clearly regulated nor clearly prohibited in most jurisdictions — it depends on the jurisdiction, the product classification, and the platform's own geo-policy. Polymarket has restricted US access under specific product and legal determinations. Azuro is sports-liquidity infrastructure and applies geo-rules through front-end apps, not a single policy document. SX Bet is wallet-first with variable access depending on jurisdiction.
"Crypto" is not a jurisdiction bypass. A user using a VPN to access a geo-restricted platform is almost always violating the platform's terms of service and potentially local law, regardless of whether detection is likely. The regulation tracker links official sources; it does not advise on individual legality. The Is Polymarket legal? page explains how to think about the access vs legality question without pretending GammaPredict is anyone's lawyer.
How to approach the access question practically
Start with your jurisdiction, not the platform. Find the official terms for each venue. If you are in the US, start from the USA ranking. If you are in the UK, start from the UK ranking. If you are in the EU or a non-listed country, the by-country page is the starting point. Access maps change. Always verify the live terms before funding.
A filings list is not a licence. A register record is not a product catalogue. The desk opens those two pages before it writes any GammaPredict table.
GammaPredict Research does not invent regulatory status from a screenshot of a homepage. When a review says “CFTC designated contract market” or “UKGC-licensed exchange,” that claim has to survive a click on an official register — not a press release, not a Twitter thread, and not our own ranking copy. This note is the desk method for those two clicks. It is not legal advice and it does not tell you whether you may fund an account.
What the CFTC DCM filings page is — and is not
The Commodity Futures Trading Commission publishes a list of designated contract markets under industry filings. That page answers a narrow question: which organisations currently appear as DCMs. It does not answer which contracts you may trade in your state, what the fee schedule is, or whether a crypto board “feels regulated.” Kalshi and ForecastEx are the two DCMs on the GammaPredict flagship list; we still send readers to the CFTC DCM filings rather than treating our table as the source of record.
What we record from that page: the operator name, that the product class is an event contract on a DCM — not a sportsbook parlay — and the date we checked. What we refuse to infer: volume, maker/taker fees, or “available to every US person.” State access and contract specs live on the operator, not on the filings index.
What a UKGC public-register record is — and is not
The UK Gambling Commission public register lists licensed gambling businesses. A hit means a named legal entity holds a licence of a stated type. It does not mean every product on that company’s website is in scope, and it does not travel as a US CFTC status. Smarkets (Malta) Limited appears as record 53378; we still start from the UKGC public register search, then open the record, then write the GammaPredict UK page.
Kalshi’s DCM status does not appear on that register. Copying the US shortlist into a UK ranking is the error this method is built to catch.
How the two pages are not interchangeable
A DCM is a US derivatives-market designation. A UKGC licence is a Great Britain gambling permission. They are different product classes with different dispute routes. The desk never writes “licensed” without naming which register we opened. Crypto-native venues such as Polymarket sit on neither page; geo policy then comes from the operator’s own help centre, which is a third primary source — not a substitute for the first two.
What this means for a reader
Open the register, then open our regulation tracker. If the two disagree, trust the register and tell us. Rankings on GammaPredict are research listings. They are not an order ticket and they are not a regulator’s letter.
