Polymarket alternatives (2026)

By the arky team · Updated 4 October 2026

A fair list of prediction markets people use instead of, or alongside, Polymarket, as of October 2026. Every claim about another platform links to its source; check each venue's own site for current details.

Why people look for a Polymarket alternative

Polymarket is the best-known crypto prediction market, trading in USDC on Polygon (Frenflow, June 2026). People search for alternatives for a few recurring reasons:

• Access. Polymarket is subject to geo-restrictions in some jurisdictions, which drives searches like "Polymarket alternative Europe", "Canada" or "Australia".
• Regulation. Some traders want a regulated exchange that pays out in dollars.
• Chain and collateral. Others want markets on the chain where their funds already sit, such as Base, BNB Chain or Arc.
• Tools. Some want prediction markets inside a wider trading app rather than a standalone site.

arky does not tell you which venue is legal where you live. Availability depends on each platform's terms and your local rules; check both before you sign up. arky's own rules are in the arky terms.

Comparison table (as of Oct 2026)

Sources: Kalshi, Polymarket and Limitless from Track360 (June 2026) and Frenflow (June 2026); Limitless collateral and model from PolymarketTrader; Myriad chains and model from Decrypt and CoinCodex; Predict.fun from Frenflow. arky from arky's own documentation.

The alternatives, one by one

Kalshi

Kalshi is a US exchange overseen by the CFTC as a designated contract market. It settles in US dollars, uses a central limit order book and verifies users with KYC (Track360). It suits traders who want a regulated, dollar-based venue rather than a crypto wallet.

Limitless

Limitless is an on-chain prediction market on Base, an Ethereum layer-2, that uses USDC as collateral and runs both order-book and AMM markets. Its catalogue leans on crypto, with sports, finance and politics too (PolymarketTrader). Track360 counts it among the closest structural peers to Polymarket (Track360).

Myriad

Myriad lets users predict with points or USDC, which makes it friendly for beginners, and runs on several chains including BNB Chain, Abstract and Linea, with both order-book and AMM markets (Decrypt).

Predict.fun

Predict.fun is a self-custodial prediction market on BNB Smart Chain that settles in USDT (Frenflow).

arky: the Polymarket alternative on Arc

arky is a trading terminal on Arc, Circle's layer-1 blockchain where USDC is the gas token and transactions are final in under a second (Arc docs). Its prediction markets are binary YES/NO markets collateralised in native USDC: each winning share redeems for 1 USDC, every market quotes a live price from its own market maker, and resolution happens onchain through vetted resolvers. The full mechanics are in prediction markets in USDC on Arc.

What sets arky apart is the rest of the app. The same terminal runs a memecoin launchpad and spot trading, so one USDC balance covers all three. Every user gets Scout, an AI trading agent that answers from live arky data and proposes trades that your wallet signs.

To be fair about the trade-offs: Polymarket and Kalshi have far larger catalogues and longer track records. arky is the newer venue, built for people who already use Arc or want to. For a closer look, read arky vs Polymarket.

How to choose

• You want a regulated US exchange that pays in dollars: look at Kalshi.
• You want the biggest crypto catalogue: Polymarket, if it is available to you.
• Your funds are on Base or BNB Chain: Limitless, Myriad or Predict.fun avoid a bridge.
• You are on Arc, or want USDC-only trading with memecoins and an AI agent in one place: arky. Start with how to trade on Arc with USDC.

Whichever you pick, read how markets resolve before you trade, and check the venue's terms and your local rules. Prediction markets can lose you the full amount you put in. For background, see how prediction markets work.
