Polymarket vs Trueo: Scale, yield and market choice (2026)

Polymarket International and Trueo both let users trade on real-world outcomes, but they differ in scale and design. Polymarket runs on Polygon and has about $316.4 million in TVL. Its markets span elections, sports, esports, crypto, finance, culture and other topics. Prices appear as percentages, and markets show volume and news context. Trueo runs on Base and has about $1.7 million in TVL. Its selection covers crypto, politics, technology and finance, with an emphasis on crypto-native questions. Trueo also describes positions as yield-bearing and lets users propose markets. Those features do not make its yield guaranteed: the rates are not published, and outcomes still depend on market resolution. TVL is a broad measure, not a promise that every market has deep liquidity. Check the volume and spread of the individual market you are considering.

Neither platform publishes a complete fee schedule. Polymarket does not state trading, deposit or withdrawal costs. Its referral page says referrers can earn 10% of fees from direct referrals and 5% from indirect referrals, but that does not reveal what a trader pays. Trueo mentions creator fees for proposed markets, without publishing rates for those fees, trading, creation or withdrawal. Its displayed yield figures are placeholders, so there is no published APY or APR to compare. Network costs may also apply: Polymarket uses Polygon and Trueo uses Base, but the project information does not give specific gas amounts. Before committing funds, check the current platform terms, the transaction details and any market-specific costs. With no published schedule or yield rate from either project, a precise cost or return comparison is not possible.

Polymarket has two audits listed, but the auditors and audit findings are not published here; an audit count is not a guarantee of safety. Trueo has no audits listed, and information about custody, admin keys or past incidents is not published. Its oracle is secured by staked TRUE, so settlement depends on the oracle’s incentives and dispute process, details the project does not explain. Both platforms also carry the general risks of smart contracts and prediction-market resolution. A market can resolve in a way that differs from a user’s expectation, even if the forecast seemed reasonable. Polymarket’s international site does not offer trading to US users; Trueo does not state regional availability. Neither publishes KYC details in this information. Prediction markets may be treated as gambling or derivatives, depending on location. Use these services only if legal where you live, and only if you are 18 or older.

Polymarket is the stronger fit if you want a broad menu and more visible activity. Its markets include sports and esports as well as politics, crypto and many other subjects. Probability-style prices, displayed volume and news headlines can help you assess a market, though they do not remove risk. The site also lists Combos and Perps alongside standard prediction markets. Trueo is more focused: it offers Yes/No markets, some conditional outcomes, market threads and activity pages. Users can propose markets, and the project says positions earn yield through its TYD mechanism. The rates are not shown publicly, and TRUE holders can stake tokens or TRUE-ETH LP tokens to support oracle security. That creates an additional token and settlement consideration. Trueo’s smaller TVL does not establish that every market is illiquid, but its market sizes are often modest and prices may move more easily.

Choose Polymarket if your priorities are a wider range of topics, visible market volume and substantially higher TVL. Its two listed audits are a point of difference, but they do not remove smart-contract, resolution or legal risk, and access is restricted for US users on the international site. Choose Trueo if you specifically want to explore yield-bearing positions or propose markets, and are comfortable with an unpublished yield rate, no listed audits and an oracle secured by TRUE. Its lower TVL makes it especially important to inspect the activity and pricing of each market rather than assume depth from the platform’s overall figures. For either choice, verify fees, availability and legality before depositing. Both are prediction-market products for adults aged 18 or older; do not stake money you cannot afford to lose.
