A prediction market aggregator pulls the same event from several prediction markets into one view. PredictStack matches equivalent markets across venues and shows each one's live price and liquidity together. You trade from one place instead of opening an account on every platform.

Neither is always cheaper. Each venue prices the same Yes/No contract independently, so the best price moves between them. PredictStack shows Polymarket's and Kalshi's prices for the same event side by side, alongside Hyperliquid, Myriad Markets, Limitless and Predict, so you can see which is cheaper right now without checking each site.

Through smart order routing. When you place a market order, PredictStack checks the matched market on each connected venue and routes your order to the best available price. If one order book can't fill it at that price, it splits the order across venues. Before you confirm, you see your average price, potential payout and estimated fees.

It means the order books of several venues work like one. An order big enough to move the price on a single exchange can be filled across Polymarket, Kalshi, Hyperliquid and others instead, so you get more size at a better average price.

Paper trading lets you trade prediction markets with simulated money. PredictStack's paper trading gives you a free $10,000 virtual balance on the same live markets and prices, so you can test strategies, learn the order types and compare venues with no real money at risk.

A Yes/No contract pays $1 if the outcome happens and $0 if it doesn't, so its price is the market's implied probability. Yes at 62¢ means roughly a 62% chance. PredictStack can also show prices as decimal, fractional or moneyline (American) odds; choose your format from the settings menu.

Yes. Market orders are routed to the best price automatically. You can also place a limit order at the price you choose, with an expiry. A limit order sits on the single venue you pick, and you can track or cancel it from the Open limit orders tab in your profile.

Yes. Hyperliquid, best known for perpetual futures, also lists outcome markets: Yes/No contracts that settle at $0 or $1, with the price as the implied probability. PredictStack shows Hyperliquid's outcome markets next to the same events on Polymarket, Kalshi and the other venues, so you can compare prices directly.

They're on-chain prediction markets: Limitless runs on Base, and Myriad Markets and Predict run on BNB Chain. Instead of funding a separate wallet for each, you can compare and trade their markets through PredictStack, next to Polymarket, Kalshi and Hyperliquid.

It depends on where you live. Prediction-market rules differ by country and, in the US, by state, and each venue sets its own eligibility. PredictStack isn't available in restricted jurisdictions, including several countries and the US states of Arizona and Nevada, and access from them is blocked automatically. Check your local rules before you trade.
