Myriad is an on-chain prediction market that prices outcomes using an automated market maker (AMM) rather than a traditional order book. It runs two kinds of markets side by side: real-money markets denominated in stablecoins, and play-money markets that use in-app points (PTS). It sits inside the crypto-media ecosystem around Decrypt and Rug Radio, and it began on the Abstract chain before expanding to additional networks.

This guide covers what Myriad is, how its AMM mechanic actually prices outcomes, why the stablecoin-versus-play-money split matters when you read the odds, who the platform is for, and how to use CoinRithm to browse and research Myriad markets before committing any real money.

TL;DR

• Myriad is an on-chain prediction market that prices outcomes with an AMM, not an order book. There is always a price to trade against, even in thin markets.
• It runs real-money markets settled in stablecoins and play-money markets that use in-app points (PTS). The two look similar but mean very different things.
• Play-money (PTS) odds reflect engagement and sentiment, not real-money conviction. Weight them accordingly when you read probabilities.
• Myriad is tied to the crypto-media ecosystem around Decrypt and Rug Radio (both under Dastan) and launched on the Abstract chain.
• CoinRithm aggregates around 60 open Myriad markets at /en/prediction-markets/myriad so you can see odds, history, and cross-source comparison in one place.
• You can paper-trade prediction market events on CoinRithm with mock USD ($10 min) before risking real money anywhere.

What Is Myriad

Myriad is an on-chain prediction market where you trade shares in the outcomes of real-world and digital events, and prices are set by an automated market maker. It was launched by Dastan, the parent entity behind the crypto-media brands Decrypt and Rug Radio, and it started on the Abstract chain before expanding to additional networks.

The defining characteristics that shape how Myriad feels and behaves:

• AMM-based pricing. Instead of matching your buy order against another trader's sell order, you trade against a liquidity pool. A pricing curve sets the cost of each outcome share, so there is always a quotable price even when few people are active in a market.
• Two currency modes. Some markets are real-money markets denominated in stablecoins. Others are play-money markets that use in-app points called PTS. This is the single most important thing to understand about reading Myriad odds, and we cover it in its own section below.
• On-chain settlement. Markets live on-chain. Positions and payouts are handled by smart contracts rather than a company custodian deciding when to release funds.
• Embedded in media. Myriad is designed to surface prediction markets alongside articles, posts, and other media content rather than only living on a standalone exchange. The prediction sits next to the thing you are already reading about.

That embedded, media-native positioning is what makes Myriad distinct from a pure trading venue. It is trying to turn passive content consumption into active forecasting, which also means a meaningful share of its markets are lightweight, culture-driven, and short-lived rather than heavyweight financial or political markets.

How Myriad Works: The AMM Mechanic

The core model is the standard prediction market one: you buy shares in an outcome, and a winning share pays out one unit (one point, or the stablecoin equivalent) while a losing share pays zero. The price of a share, somewhere between 0 and 1, reflects the market's implied probability of that outcome.

What is worth understanding on Myriad specifically is how those prices are produced.

An AMM Prices Outcomes Differently From an Order Book

On an order-book venue, a trade only happens when your order meets someone else's opposing order at an agreed price. If nobody is offering to sell YES shares near the price you want, your order sits unfilled, or you cross a wide spread and pay a worse price. Thin order books produce large gaps between the best buy and best sell price.

An AMM works differently. Instead of matching two traders, it holds a pool of outcome shares and prices them with a formula. When you buy YES shares, you remove YES shares from the pool and add funds to it. That imbalance moves the price: YES gets more expensive, and the opposing outcome gets cheaper. When someone buys the other side, the balance shifts back. Because the pool is always willing to quote a price off its curve, you can enter and exit without waiting for a specific counterparty to appear. This is why AMMs can keep functioning in low-liquidity conditions where an order book would stall.

The practical consequences for a trader:

• There is always a price. You are not blocked by an empty book. Even a quiet market gives you a tradeable quote.
• Your own trade moves the price. In a thin pool, buying a meaningful size walks the price up as you go. The bigger your order relative to the pool, the worse your average fill. This is slippage, and it is the AMM equivalent of crossing a wide spread.
• Liquidity depth still matters. A deep pool absorbs your trade with little price impact. A shallow pool does not. Position sizing on Myriad should scale with how much liquidity the specific market holds, not with how confident you feel.

Some Myriad markets may use an order-book style rather than the AMM, and the exact pricing curve and parameters can change between versions. Treat the description above as the general AMM logic and check the individual market and the venue documentation for the specifics of any market you actually trade.

Prices as Probabilities

The probability logic is the same as on any prediction market. A share priced at 0.70 implies roughly a 70% market-implied probability. If you believe the true probability is higher, buying has positive expected value before fees. If you believe it is lower, the opposing outcome is the better buy.

One caveat that is bigger on Myriad than elsewhere: that 0.70 only carries the usual meaning if it is a real-money market. In a play-money PTS market, the number reflects points-based sentiment, which is a weaker signal. More on that in the next section.

For the full probability and payout mechanics explainer, read How Prediction Market Probabilities Work.

Resolution

When the event concludes, the market resolves and the winning outcome's shares become worth one unit each while losing shares become worthless. Resolution relies on the criteria and data sources defined for that market. As with any prediction market, the resolution rules encoded for the market are what govern the payout, not your interpretation of what "should" have happened.

Before trading any Myriad market, read the resolution criteria on the market page and check:

• What data source or oracle determines the outcome
• The exact definition of the resolving event
• The resolution date and window
• What happens in ambiguous or edge-case scenarios

Fees and On-Chain Costs

Myriad charges trading-related fees, and there are on-chain transaction costs on top. Exact fee levels and gas handling can change between versions and between the currency modes and chains Myriad supports, so we do not print a specific fee number here that could go stale and mislead you. Check the venue directly for current fees, and see Prediction Market Fees Comparison for how fee structures differ across platforms and why they matter for small positions.

Stablecoin Markets vs Play-Money (PTS) Markets

This is the part that trips people up, and it is the most important thing to internalize before you read a single Myriad odds number.

Myriad runs two kinds of markets that can look almost identical in the interface:

Real-money markets are denominated in stablecoins. When you buy a share, you commit real value. If you are wrong, you lose real money. The odds in these markets are backed by financial conviction: someone put actual capital behind that price.

Play-money markets use PTS, Myriad's in-app points. You can forecast without committing real capital. This is great for practice, for engagement, and for lowering the barrier to participating. But it changes what the price means.

Why the Distinction Changes How You Read the Odds

The whole reason prediction-market prices are treated as useful probability estimates is that real money disciplines them. If a real-money market misprices an outcome, a trader can profit by correcting it, and that pressure pulls the price toward a fair estimate. That mechanism is the source of the "wisdom of the crowd" that makes these markets worth watching.

In a play-money PTS market, that discipline is much weaker. There is little or no financial cost to being wrong, so prices can drift on enthusiasm, fandom, or whichever side is more fun to back. A PTS market sitting at 70% tells you something about sentiment and engagement among participants. It does not carry the same weight as a stablecoin market at 70% where capital is genuinely at risk.

Neither is bad. They serve different purposes:

• Use PTS markets to learn the mechanics, gauge community sentiment, and participate without financial risk.
• Weight real-money stablecoin markets more heavily when you are using Myriad odds as an actual probability estimate or comparing them against other venues.

How to Tell Which Is Which

Check the currency and market details before you treat any Myriad number as a probability. If it is a PTS points market, read it as sentiment. If it is a stablecoin market, read it as a real-money implied probability, subject to the usual caveats about liquidity depth and how thin the pool is. On CoinRithm, the venue and market context help you keep these straight when you compare Myriad against other sources.

Who Myriad Is For

Myriad fits a specific profile:

• You are comfortable in an on-chain, wallet-based environment.
• You like the idea of forecasting on culture, media, crypto, and current-events questions that show up alongside content, not only heavyweight financial or political markets.
• You want a low-friction way to start, which the play-money PTS mode provides before you commit real stablecoin capital.
• You understand that an AMM means your own trade moves the price in thin markets, and you size positions accordingly.

If you are new to prediction markets generally, the PTS play-money mode is a genuinely useful on-ramp, because you can learn how buying and selling outcome shares behaves without risking money. Just keep the sentiment-versus-conviction distinction in mind when you graduate to reading real odds.

If you are an experienced trader hunting the deepest liquidity across broad event categories, Myriad is one venue to track rather than the only one. Its strength is breadth of lightweight, media-native markets and an always-quotable AMM, not necessarily the deepest books on any single large event.

Ground Truth: What We Know and What We Don't

This is a direct honesty note. Myriad is an evolving platform, and some details are easier to state with confidence than others.

What we are confident about:

• Myriad is an on-chain prediction market that prices outcomes with an AMM.
• It runs both real-money stablecoin markets and play-money PTS (points) markets.
• It is associated with the crypto-media ecosystem around Decrypt and Rug Radio, under Dastan.
• It launched on the Abstract chain and has expanded to additional networks.
• CoinRithm aggregates its markets and tracks odds.

What you should verify directly with Myriad:

• Current fee structure (trading fees, protocol fees, gas handling) across its currency modes and chains.
• Exactly which chains and stablecoins are supported right now, and for which markets. This has expanded over time and may change again.
• Whether a specific market uses the AMM or an order-book model, and its exact pricing parameters.
• Current legal or geographic restrictions. On-chain prediction markets operate in a shifting regulatory environment; what applies today may differ in six months.
• Current liquidity levels, which vary a lot between a headline market and a quiet, culture-driven one.

For any of the above, treat this article as directional and check myriad.markets directly for current terms. We will not invent a fee number or claim geographic availability without current data, because that is how users get misled.

Myriad vs Other Prediction Markets

The platforms differ along a few key axes. This is a directional comparison. For a structured way to compare venues on odds, liquidity, and fees, read How to Compare Prediction Markets.

The practical read: if you want an always-quotable AMM, a play-money mode to practice with, and a lot of lightweight media-native markets, Myriad fits. If you want the deepest on-chain liquidity across broad event categories, Polymarket is larger. If you are in the US and want regulated access with fiat, Kalshi is the clearer path.

These are not mutually exclusive. Many people track several venues and read odds across them. CoinRithm's prediction markets hub is built for exactly that kind of cross-platform research.

How to Research Myriad Markets on CoinRithm

CoinRithm aggregates Myriad markets alongside Polymarket, Kalshi, Limitless, Manifold, and others. You can browse odds, view odds history, and compare across sources without connecting a wallet or hopping between platforms.

The dedicated hub for Myriad is: coinrithm.com/en/prediction-markets/myriad.

From there you can:

• See the aggregated open Myriad markets (around 60 at the time of writing)
• View current implied probabilities for each outcome
• Check odds history (24h, 7d, 30d charts where data is available)
• Compare Myriad odds against similar markets on other platforms
• Read resolution rules without needing a wallet

Useful Research Steps Before Trading on Myriad

1. Check the odds on CoinRithm first

Open the Myriad hub and find the market you care about. Check whether a similar market exists on another venue. If Myriad shows 65% and Polymarket shows 72% on the same underlying question, that spread is worth understanding before you commit.

2. Confirm whether it is a stablecoin or PTS market

This is the Myriad-specific step. If the price you are looking at comes from a play-money PTS market, read it as sentiment, not as a real-money probability. When you compare against other venues, make sure you are comparing a real-money Myriad market against their real-money markets.

3. Read the resolution rules

The market detail surfaces the resolution criteria. Read them before opening a position. Knowing the exact data source and resolution window prevents the most common and most avoidable losses.

4. Check liquidity depth

Because Myriad prices with an AMM, thin pools mean your own trade moves the price against you. CoinRithm shows volume and liquidity figures where available. Size your position to the pool, not to your conviction.

5. Track the odds history

The 24h and 7d trend on CoinRithm's market detail shows how implied probability has moved. A market that drifted from 40% to 70% over the past week may be pricing in recent news you should understand before buying at 70%.

6. Open on Myriad when ready

CoinRithm is a research and discovery layer, not a trading interface. Once you have done the research, open the market directly on Myriad to place your trade. CoinRithm is not Myriad, is not affiliated with Myriad, and is not a broker. CoinRithm is a research tool.

Paper Trading Prediction Markets on CoinRithm

If you want to practice prediction market thinking without risking real money on Myriad (or any other platform), CoinRithm supports paper trading for prediction market events with mock USD.

The minimum paper trade size is $10.

This lets you:

• Get used to reading odds and making probability judgments
• Track whether your reads are consistently good before scaling up
• Practice position sizing without real financial consequences
• Develop a research process before applying it to real money

Myriad's own PTS points mode is another way to practice on the platform itself. The difference is that CoinRithm's paper trading lets you build and test a cross-venue research process in one place, with mock USD, across every source it aggregates. If you are consistently losing mock money, that is a useful signal to pause before using real stablecoin funds on Myriad.

Common Mistakes When Reading Myriad Odds

Treating a PTS price like a real-money probability

This is the big one. A points market at 70% is a sentiment reading, not a capital-backed forecast. If you copy that number into a decision as though it were a stablecoin market, you are trusting a weaker signal than you think.

Ignoring slippage in thin AMM pools

The AMM always quotes a price, which is convenient, but a shallow pool means a meaningful buy walks the price up as you fill. Check the liquidity depth and expect a worse average price on larger orders in quiet markets.

Assuming Myriad works exactly like Polymarket or Kalshi

Myriad is a different protocol with a different pricing model and a play-money mode neither of those has. Do not carry over assumptions about resolution, liquidity, or what a price means. Read the Myriad-specific details.

Skipping the resolution rules

On-chain settlement is governed by the encoded criteria, not by common sense. The single most common way experienced traders lose money on an unfamiliar venue is failing to read exactly how a market resolves.

Forgetting on-chain transaction costs on small positions

Trading fees plus on-chain costs can eat a meaningful share of a small position's potential profit. Factor total cost in before entering, especially for low-stake trades.

Frequently Asked Questions

Is Myriad real money or play money

Both. Myriad runs real-money markets denominated in stablecoins, where you commit and can lose real value, and it also runs play-money markets that use in-app points called PTS. They can look similar in the interface, so always confirm which currency a market uses before you treat its price as a real-money probability.

How does Myriad work

You buy and sell shares in the outcomes of events. Prices are set by an automated market maker: you trade against a liquidity pool, and a pricing curve moves the price as shares are bought and sold, so there is always a quotable price even when few people are active. A winning share pays out one unit and a losing share pays zero. Markets settle on-chain based on their resolution criteria.

What is PTS on Myriad

PTS is Myriad's in-app points, used for play-money markets. It lets you forecast and participate without committing real capital, which makes it a useful practice and engagement mode. The trade-off is that PTS prices reflect sentiment rather than real financial conviction, so they are a weaker probability signal than the stablecoin markets.

Myriad vs Polymarket: what is the difference

The main structural differences are the pricing model and the currency modes. Myriad prices most markets with an AMM (a pool and a curve) and offers both stablecoin and play-money PTS markets, and it is built to sit alongside media content. Polymarket uses an on-chain order book, trades in USDC, and has the largest on-chain liquidity across broad event categories. Many people track both and compare odds across them.

What chains and stablecoins does Myriad use

Myriad launched on the Abstract chain and has expanded to additional networks, with stablecoin support that has grown over time. Exactly which chains and stablecoins apply to a given market can change, so verify the current list directly on myriad.markets before depositing.

Is Myriad safe

On-chain settlement means smart contracts handle positions and payouts rather than a company deciding when to release funds, which reduces custodial risk. But smart contract bugs are a real risk on any on-chain platform, thin AMM pools carry slippage and manipulation risk, and the regulatory posture toward on-chain prediction markets varies by country and can change. Verify current status and risks directly with Myriad before depositing significant funds.

Where can I research Myriad markets before trading

CoinRithm aggregates Myriad markets at coinrithm.com/en/prediction-markets/myriad. You can browse odds, read resolution rules, check odds history, confirm whether a market is stablecoin or play-money, and compare against other platforms, with no wallet required.

Conclusion

Myriad is an on-chain prediction market with two features that set it apart: it prices outcomes with an AMM rather than an order book, so there is always a tradeable price, and it runs both real-money stablecoin markets and play-money PTS markets. That second point is the one to remember. A price only carries full probability meaning when real capital is behind it, so read PTS markets as sentiment and weight the stablecoin markets when you are treating odds as a genuine forecast.
