What are the best Polymarket alternatives?

Prediction markets aren't a category my ranking data or curated tool directory covers, so I'll answer this from general knowledge — that means descriptive facts about what each platform is and how it's positioned, not live prices or volume numbers. Here's how the main Polymarket alternatives line up:

Kalshi — the closest thing to Polymarket for US users. It's regulated by the CFTC as a real exchange, uses real USD (not USDC), and covers elections, economic data, and sports. Trade-off: real-money, no crypto token, and you have to be a US resident with KYC to use it. → kalshi.com

Azuro — a decentralized, open prediction-market protocol on EVM chains (Polygon, Gnosis, Base). It powers a bunch of front-ends rather than being one app, and it has real liquidity pools under the hood. More permissionless than Polymarket, less of a single polished interface. → azuro.io

Overtime (by Thales) — sports and crypto price prediction markets on Optimism and Base. Crypto-native like Polymarket (positions are tokenized), with a strong focus on sports lines. → overtimemarkets.xyz

Omen / Gnosis — prediction markets built on Gnosis Chain's conditional-token framework, which is actually the same underlying tech Polymarket was originally built on. Fully decentralized and open, but lower liquidity and a less polished UX. → gnosis.io

Hedgehog Markets — a Solana-native prediction market, similar feel to Polymarket but on Solana's chain. → hedgehogmarkets.com

Augur — the original decentralized prediction market on Ethereum. Historically important but now largely legacy with minimal activity; worth knowing as context rather than a real day-to-day alternative.

How to pick between them:

• You're in the US and want mainstream markets (elections, economics) → Kalshi.
• You want a fully on-chain, permissionless protocol → Azuro or Omen.
• You want crypto-native sports and price markets → Overtime or Hedgehog.

One caveat worth stating plainly: Polymarket dominates crypto prediction-market liquidity, so most alternatives have thinner books and wider spreads on the same events. None of this is investment advice — treat it as a feature comparison and verify each platform's current availability in your region.
