CasinoTrust now rates two prediction platforms — 1win Markets and Polymarket — and they answer opposite questions: one is far easier to fund and use, the other publishes how its prices and settlements work. This comparison sets both against the regulated US exchange model and against the sportsbooks most readers already use.

A prediction market is not a bookmaker. You trade contracts that pay $1 if an event happens and $0 if it does not, against other traders rather than against the house, and the price — say 62 cents — is the market's probability estimate. That structural difference, not the branding, is what separates Polymarket and regulated exchanges such as Kalshi from the sportsbooks in our sports betting comparison. 1win Markets sits between the two: it shows the same yes/no event cards, but 1win does not publish whether the price comes from a peer-to-peer book or is set by the operator, so it should be read as operator-set and not described as an exchange. This page explains where each model wins and which one suits you.

Four models side by side

Head-to-head winners by criterion

Licensing and safety

This is the decisive difference. Regulated US exchanges are designated contract markets overseen by the Commodity Futures Trading Commission, with cleared trades and segregated customer funds. Tier-1 sportsbooks such as bet365 and Betsson answer to national gambling regulators with independent dispute bodies. Polymarket's global venue is an unregulated on-chain protocol: your funds sit in a wallet you control, trades settle by smart contract and disputes are resolved by the UMA optimistic oracle, which has produced contested outcomes on ambiguously worded markets. Polymarket's US-facing arm operates separately under CFTC regulation following its acquisition of a licensed exchange, so the protection you get depends on which front door you use — see the Polymarket brand guide for the current status in your jurisdiction. 1win holds a Curaçao gambling licence, and Markets sits inside that gambling account rather than under an event-contract regulator; more importantly for a trader, 1win publishes no written resolution-source policy for Markets, so if a settlement looks wrong there is no stated rule or named source to hold it against. The 1win brand guide sets out what the licence does and does not cover.

Markets and pricing

On high-volume political, macroeconomic and crypto markets, Polymarket's order book is often tighter than any bookmaker's odds: a one- or two-cent spread on a liquid market is equivalent to a 1–2% margin, against a 4–8% overround on a typical sportsbook market. On thin markets the picture reverses — spreads of ten cents or more are common, and a market order can move the price against you. Regulated US exchanges show the same pattern on a narrower set of markets. For mainstream sport, sportsbooks still win comfortably on breadth and in-play depth; prediction markets list major finals and futures, not the fourth-tier fixtures or player props that 1xBet prices.

1win Markets is broader than it first looks and shallower than it sounds. The format is binary: pick an event, answer a yes or no question, and the card shows the wording, the two outcomes, the current odds and a deadline. Categories run across politics, sports, culture, tech, space and celebrities, and on 17 July 2026 1win added crypto price markets — a HYPE year-end price market and a HYPE-versus-Solana market-cap market, an XRP 2026 price target and a Dogecoin year-end forecast. What the cards do not show is a book. 1win does not publish whether those odds come from peer-to-peer trading or are set by the operator, and there is no fee schedule, so the price cannot be checked against depth the way a Polymarket price can. Read 1win's odds as a bookmaker's price on an event question, compare them with Polymarket where the same event is listed, and take the better number rather than assuming either venue is structurally cheaper.

Payments and payout speed

Polymarket accepts only USDC on the Polygon network. Funding means buying USDC on an exchange, bridging or withdrawing it to Polygon and connecting a wallet — a process that takes a newcomer an hour and costs a few dollars in fees, but thereafter deposits and payouts are near-instant and without a minimum beyond about $1. Regulated US exchanges accept US dollars by bank transfer and card with conventional processing times, and withdrawals follow banking rails. Sportsbooks credit winnings instantly but withdrawals take one to five business days at regulated books, as documented in our sports betting comparison. 1win is the easiest of the four to fund: card or crypto deposits land in the ordinary account balance with no wallet, no bridging and no on-chain steps, and payouts run from minutes to 24 hours. The trade is custody — your balance sits with the operator rather than in a wallet you control — and, because no fee schedule is published, you cannot price the convenience before you use it.

Bonuses and promotions

Polymarket runs almost no promotional programme — its bonus score of 5.5 reflects occasional liquidity rewards rather than sign-up offers — and regulated exchanges are similarly restrained. Sportsbooks compete on welcome packages and free bets, which are valuable only after you net out the wagering conditions. 1win is at the other end of the range with a bonus score of 9.6, but that programme is built around its casino and sportsbook: before counting an offer as value on a prediction position, check the terms to see whether Markets activity qualifies at all. If promotions drive your choice, 1win and the bookmakers win; if price does, they do not.

Mobile and usability

Polymarket's iOS and Android apps score 8.6 for mobile: clean order entry, portfolio view and push notifications on resolution. The wallet set-up remains the usability hurdle. 1win scores 9.3 for mobile, with an Android APK and an iOS app that carry Markets alongside casino, sportsbook and poker in one session — there is nothing to install beyond the app and no wallet to configure, which is exactly the hurdle Polymarket has not cleared. The flip side is what the interface leaves out: you see a question, odds and a deadline, not an order book you can inspect before committing. Regulated exchanges offer conventional fintech-style apps with bank funding. Sportsbook apps from bet365 and Betsson are the most mature in the group, with streaming and cash-out, but they solve a different problem.

Support

Polymarket has no live chat — support runs through a help centre, email and community channels, which is why it scores 7.0 for support. 1win runs live chat and scores 8.8, and on a platform with no published resolution policy that channel is doing more work: it is the only route to a human when a settlement is queried. Regulated exchanges and tier-1 sportsbooks offer the same live chat with agents who can see your account, backed by a written rule set. If you expect to need help with a disputed resolution, the absence of live support at Polymarket is a real cost — but so is arguing a settlement with an agent when nothing was published to argue from.

Which should you use?

• You trade politics, macro or crypto events and want the tightest prices: Polymarket — accept that you are your own custodian and that the global venue is unregulated.
• You are in the US and want regulated event contracts with bank funding: a CFTC-regulated exchange such as Kalshi, or Polymarket's US-regulated arm where available.
• You bet mainly on sport, especially in-play: a licensed sportsbook — bet365 for protection and depth, Stake if you want crypto funding with a bookmaker product.
• You want to hedge or exit positions before the result: either prediction market, where you sell at market price rather than taking a bookmaker's cash-out.
• You are new to any of this: read bankroll management first; a prediction market's price is a probability, and sizing against it is the whole skill.
