01.Destination versus embedded
A standalone market attracts people who came to trade, which tends to mean more price-sensitive participants and faster correction of obvious mispricings. An embedded market attracts readers of the surrounding content, which brings in participants who care about the topic more than the price. Neither audience is better, but they price differently, and that is worth knowing before you read either as a forecast.
- Polymarket: a destination, so participants are largely there to trade.
- Myriad: distribution through media surfaces, so participation follows editorial attention.
- Embedded markets can stay mispriced longer simply because fewer arbitrageurs see them.
02.What gets listed
Polymarket lists what people will trade, across politics, economics, sport and culture. A media-integrated venue lists what fits the surrounding coverage, which produces a narrower and more topical set tied to whatever the publisher is writing about. If you want breadth, that difference matters.
- Polymarket: broad coverage driven by trading demand.
- Myriad: topical coverage driven by editorial context.
- Check where a market's participants came from before treating its price as consensus.
03.Liquidity and depth
Depth follows attention. Polymarket's largest markets absorb serious size; embedded markets are typically thinner, which means wider spreads and more slippage on anything but a small position. This is the practical constraint that decides where a real position goes, regardless of which interface you prefer.
- Check depth before sizing on any venue, but especially a thinner one.
- Thin markets punish market orders — use limits where the venue supports them.
- A price with no size behind it is an opinion, not a market.
04.Building on either
Polymarket's public APIs and onchain settlement are why this directory exists. Newer or embedded venues generally expose less, and what they do expose changes more often. Verify current API availability directly rather than assuming parity.
- Polymarket: CLOB, Gamma and data APIs, plus fully public onchain state.
- Myriad: check current developer documentation at the source.
- Cross-venue tooling is the exception rather than the norm.
