Polymarket vs Myriad Markets, explained

What these two platforms are

Both Polymarket and Myriad turn a question about the future into a number that reads as the crowd's implied probability, which is why they are increasingly mentioned together. Polymarket is, as of 2026, the largest prediction market by volume: an on-chain venue that settles in USDC on the Polygon blockchain, where participants take positions and the resulting price between zero and one reads as the market's implied probability. It was founded in 2020 by Shayne Coplan, was valued near nine billion dollars in 2025, and received a 2026 CFTC amended designation to operate a US-facing exchange alongside its existing platform.

Myriad Markets is much newer. It launched in January 2025, built by Dastan, the parent company of the crypto media outlets Decrypt and Rug Radio, and it positions itself as a social-first, multichain prediction market. Many of its questions are tied to the editorial output of those media partners, and it runs two kinds of markets at once: free points markets, where an in-platform currency lets newcomers learn the mechanics and build a leaderboard reputation, and real-money USDC markets. If you are new to reading either kind of figure, the companion explainer on what Polymarket is and how it works walks through the market side first.

Feature comparison (as of 2026)

The table sets Polymarket and Myriad side by side on the dimensions that actually differ. Each cell describes a current fact as of 2026. Fees, chain support, regional access, and platform structure all change over time, so treat each platform's own published pages as the authoritative source.

Where the probability comes from

Unlike a forecasting platform that polls people for estimates, both of these are markets, so both arrive at a probability through trading. A contract trades between zero and one, and as participants keep buying and selling, the price moves to reflect what they are collectively willing to pay. A contract at 0.62 reads as a 62 percent implied probability on either venue. The companion guide on how to read implied probability covers why that number is an observation rather than a verdict.

The mechanism underneath differs. Polymarket matches buyers and sellers through a central limit order book, so the price is the clearing point of standing orders. Myriad blends an automated market maker, where algorithmic liquidity sets and updates the price, with order-book markets, and it lets any user supply liquidity to a market. Both approaches can be pulled by thin liquidity and trader composition, which is why we treat any single price as an observation. The companion guide on volume versus liquidity explains why a thin market moves more on a small order.

How each platform resolves a market

Resolution is where the two diverge in maturity. On Polymarket, a market settles on-chain through a decentralized oracle that uses the UMA optimistic-oracle dispute system: an outcome is proposed, and it can be challenged within a window before it finalizes, a process that is extensively documented. Myriad also settles on-chain, using decentralized resolution sources and oracles, with many markets tied to the editorial coverage of its media partners; its public resolution framework is less standardized than Polymarket's as of 2026. Both publish per-market rules you can read before a question settles. Because the figures Cent Signals publishes are snapshots of public Polymarket data, the methodology page explains exactly which public sources those numbers come from.

Chains, cost, and available regions

On infrastructure, Polymarket settles in USDC on Polygon, a single Ethereum scaling network, while Myriad is multichain: it launched on Abstract, added the Ethereum Layer-2 network Linea in mid-2025, and also runs on Celo. On cost, as of 2026, Polymarket historically charged nothing to trade and has since layered in a taker-fee model that varies by category, while maker orders that add liquidity to the book pay no fee. Myriad's points markets are free to use, and it does not publish a single standardized fee schedule for its USDC markets, which use dynamic fees on order-book markets. On scale, Polymarket is by far the larger venue, valued near nine billion dollars in 2025, while Myriad had passed one hundred million dollars in cumulative USDC volume with much smaller recent activity. Regional access for both varies by jurisdiction and changes over time, so the platforms' own current pages are the authoritative reference.

How Cent Signals fits in

Cent Signals is neither of these platforms and not a place to take a position. It is a free, independent reading desk for the public data Polymarket exposes, with no account and no wallet required, because it only reads and explains public on-chain and public-API data. It indexes markets with real activity behind them and the wallets that transact large notional, then explains what the prices and positions describe. You can see that in practice on a market page such as the market on Ivory Coast winning the 2026 FIFA World Cup, or on a tracked wallet such as this Polymarket trader and the positions it currently holds. Those pages report observations of public data, never instructions.
