Polymarket is the biggest name in prediction markets, but it is not the only place to trade real-world events, and for a lot of people it is not even available. Here are the apps worth knowing, ranked and reviewed.
Polymarket runs on Polygon. You buy and sell yes/no shares on the outcome of an event, and the price moves with the market's read on the odds. Its focus is politics and sports, it has the deepest liquidity in the category, and it did about $4.84B in volume over the last 30 days. If you want the widest range of high-liquidity political and sports markets, it is still the reference point.
People look for alternatives for a few concrete reasons. The main international Polymarket app is geoblocked in the US, though a separate regulated Polymarket US launched in December 2025. Some traders want lower fees, some are hunting tokens and airdrops from newer platforms, and some just want markets Polymarket does not carry, like hourly crypto bets, on-chain sports, or macro contracts.
This list starts with SmartX, which is a trading terminal for the Polymarket ecosystem rather than a separate venue. After that, the venues are ordered roughly by 30-day trading volume and our editorial rating.
SmartX
SmartX is an AI trading terminal that sits on top of the Polymarket ecosystem. You trade the same Polymarket markets, so you are not giving up liquidity, but you get tools Polymarket's own interface does not have. It tracks smart-money wallets live, pushes trade signals, and runs a market radar that flags fast moves, open-interest build-up, and smart money entering a position. Charts, research, and execution sit in one place, and the fee is 0.5%. If you already trade Polymarket markets and want to see what informed wallets are doing before you commit, this is the pick.
Kalshi
Kalshi is a CFTC-regulated exchange based in the United States, and it is the clean legal option for US traders. It did $12.14B in 30-day volume, the most on this list, with deep liquidity across its contracts. Fees follow a maker/taker model, and there is no token, so airdrop hunters will not find one here. If you are a US person who wants prediction markets without the access questions, Kalshi is the answer. See our Polymarket vs Kalshi comparison for the details.
US only.
Polymarket
Polymarket is the deepest market in the category, with $4.84B in 30-day volume and the best liquidity for politics and sports. Effective fees come out around 1%. The international app is geoblocked for US IP addresses, and a separate regulated Polymarket US (from QCX) launched in December 2025 for US residents. A POLY token and airdrop have been confirmed by Polymarket's CMO, which is one more reason traders are active on it now. If you want the tightest spreads on major events, this is where they are.

InsightX
InsightX runs on Mantle and posted $492M in 30-day volume. Its angle is AI-generated odds, and it has leaned into World Cup markets. There is no token yet, which for some traders is a reason to get involved early. Liquidity is solid for a newer venue, though the market range is narrower than Polymarket's.
Availability varies by region.
OPINION
OPINION is a BNB-chain market focused on macro contracts, and it did $416M in 30-day volume. It has an $OPN token plus a points program, so it fits traders who want exposure to economic and macro outcomes while farming rewards. If your interest is rates, inflation, and broad market questions rather than sports, it is worth a look.
Availability varies by region.
Predict.fun
Predict.fun is a BNB-chain prediction market with $381M in 30-day volume. It is built around points and airdrop farming, so activity here can earn you a position ahead of a token event. Markets and liquidity are decent, and the interface is straightforward. For traders who want to be early on a platform that is still distributing rewards, it is one of the stronger options.
SX Bet
SX Bet runs on its own SX Network and did $177M in 30-day volume. The focus is sports betting rather than broad event markets, and it converts $SX into credits for use on the platform. If sports is your main interest and you want an on-chain venue built specifically for it, SX Bet covers that lane well.
Availability varies by region.
Limitless
Limitless is a Base-chain market that specializes in hourly crypto markets, with $123M in 30-day volume. It runs an $LMTS token and a seasons system, which rewards regular activity. The short-duration format suits traders who want fast settlement on crypto price questions rather than long-running political contracts. Its editorial rating is high for its size.
Availability varies by region.
PredictStreet
PredictStreet is built on ADI Chain and did $47.6M in 30-day volume. It offers free-play World Cup markets, which is a low-risk way to try the format, but liquidity is thin, so real-money depth is limited. Treat it as a place to learn the mechanics or follow a specific event rather than a primary trading venue.
Availability varies by region.
TurboFlow
TurboFlow runs on BNB and Solana and did $13.6M in 30-day volume. It offers 1000x binary markets with house liquidity, and it charges a profit-only fee, so you pay when you win. There is a points program. The high-multiplier format is aggressive, and it is aimed at APAC users, so access elsewhere may be limited.
Region-focused (APAC); availability varies.
Overtime
Overtime is an on-chain sports market on Optimism and Arbitrum, with $9M in 30-day volume. It has an $OVER token plus an XP system for active users. Volume is modest, so liquidity varies by market, but the on-chain sports format is well built and the rewards give an extra reason to use it.
Availability varies by region.
PancakeSwap Prediction
PancakeSwap Prediction offers fast up/down rounds on the BNB price, with $8.5M in 30-day volume. It uses pool liquidity and charges a 3% fee, which is high relative to the rest of this list. The format is simple and quick, but the fee and single-market focus make it more of a side venue than a main one.
Availability varies by region.
World
World is a Solana-based prediction market aimed at Phantom wallet users, with $6.5M in 30-day volume. If you already keep funds in Phantom and want to trade events without bridging to another chain, it removes a step. Volume is on the low end, so check depth on the specific market you want before sizing up.

Which prediction markets have airdrops?
A POLY token and airdrop have been confirmed by Polymarket's CMO. Predict.fun runs points and airdrop farming, OPINION has $OPN plus points, and Limitless runs an $LMTS token with seasons. Overtime and SX Bet also have tokens with XP or credit systems. Token plans can change, so check each platform's current program before farming.
Can I use Polymarket with a VPN?
Polymarket restricts US persons in its terms of service, and using a VPN to get around geographic restrictions can violate those terms and put your funds or account at risk. We do not recommend trying to bypass platform rules. If you are in a restricted region, use a venue that is available to you, such as Kalshi in the US.
Are prediction markets legal?
It varies by country and, in the US, by regulator. Kalshi operates as a CFTC-regulated exchange in the United States, while other platforms are offshore or on-chain and are not available everywhere. Legal status changes, so check the rules in your own jurisdiction. This article is general information and not legal advice.
