Fortune Protocol has integrated Polymarket liquidity into Fortune Markets, adding another source of prediction markets alongside Predict.fun while giving users a single interface to compare liquidity, volume and market probabilities.
Fortune Protocol said in an X announcement on Aug. 25 that Polymarket liquidity was now live on the platform, bringing markets from both Polymarket and the previously integrated Predict.fun into what it describes as a unified market layer.
More markets. More liquidity. One Fortune.🥠@Polymarket liquidity is now live on Fortune alongside @predictdotfun, bringing more markets and liquidity into one unified market layer.

The integration allows Fortune Markets users to browse event markets supplied through different liquidity sources without moving between separate prediction platforms. Market information is displayed through a redesigned interface that lets traders compare liquidity, trading volume and implied probabilities before selecting a market.
Alongside the additional liquidity, Fortune has changed its trading flow to include outcome selection and a position preview. Its Portfolio section has also been combined into one view covering open positions, settled markets and a user’s full trading history.
“More markets. More liquidity. One Fortune,” the project said while announcing the update.
Fortune Protocol brings Polymarket liquidity into one interface
Fortune Protocol describes Fortune Markets as a prediction market product built around aggregated access, with liquidity from outside venues brought into a common interface. The latest addition puts Polymarket beside Predict.fun as the two named liquidity sources currently available through the product.
Under the new market design, users can examine comparable information across markets before trading, including how much liquidity is available, the volume recorded by a market and the probability implied by its pricing.
Fortune said the updated trading process also lets a user select an outcome and preview the resulting position before proceeding. Once trades have been made, the unified Portfolio provides access to active positions, markets that have already resolved and previous trading activity.
The project said it plans to continue integrating liquidity from established prediction market venues as it builds the unified market layer. According to Fortune, combining different liquidity sources is intended to give users a more efficient way to access and trade prediction markets from one place.
Predict.fun already has integrations elsewhere in the crypto market. In April, crypto.news reported on Predict.fun powering prediction-market access inside Binance Wallet for eligible users.
Through that integration, prediction-market activity is executed on-chain using Predict.fun smart contracts, while Predict.fun operates the events, pricing and resolution rules. Users can access markets covering areas including sports, economics, world events, culture and crypto, with outcome prices representing the probability assigned by traders to each result.
Polymarket has been expanding its own liquidity infrastructure
Fortune’s addition of Polymarket comes after the prediction market operator made changes to its own trading infrastructure earlier this year.
In April, Polymarket launched CLOB v2, introducing new exchange contracts, a rewritten central limit order book backend and Polymarket USD, or pUSD, as its collateral token.
The upgrade was accompanied by a $1 million liquidity rewards program designed to attract market makers and deepen order books across Polymarket’s event contracts. Polymarket also added support that allows front ends and other builders to route orders and track trading flow through its infrastructure.
Those changes matter for aggregation products because liquidity determines how easily traders can enter and exit a prediction market and how closely prices can track changes in market expectations. Fortune’s redesigned interface makes liquidity one of the metrics displayed when users compare available markets.
Polymarket’s trading model uses event contracts whose prices change as traders buy and sell different outcomes. A contract priced at 60 cents, for example, represents an implied probability of roughly 60% before considerations such as market structure, liquidity and trading costs.
Fortune has not disclosed separate volume or liquidity figures for the Polymarket markets made available through its interface.
Prediction market liquidity has drawn professional trading firms
Liquidity has become a larger focus across prediction markets as trading activity has increased.
During May, Wintermute entered prediction market making, providing continuous two-way quotes across several prediction platforms. Aggregate monthly trading volume across the sector had passed $20 billion at the time, while Wintermute described liquidity as still early by institutional market standards.
Jake Ostrovskis, Wintermute’s head of OTC trading, said there was “clear demand for these markets” but liquidity remained insufficient. The firm said tighter spreads and more trading capacity could improve the quality of probabilities produced by event markets.
Market makers provide competing bids and offers that can reduce the gap between prices available to buyers and sellers. For prediction platforms, deeper order books can also make it easier for traders to execute larger positions without moving a contract’s price as sharply.
Fortune’s model approaches the same liquidity issue from the user interface side by pulling markets supplied by multiple venues into one place and allowing traders to examine them before choosing where to take a position.
Aggregating prediction markets is becoming a separate product category
Other firms have also started building products designed around access to several prediction platforms.
Paradigm has been developing a prediction terminal for professional traders and market makers. The project, which began in late 2025, was designed to provide tools for analyzing and routing liquidity across on-chain and regulated prediction platforms.
Paradigm had also begun aggregating prediction-market data into a public dashboard and was considering an internal market-making operation and an index that could package several event markets into one product.
Fortune’s product is focused on bringing the markets themselves into a unified trading interface. Its latest update adds Polymarket to the Predict.fun liquidity already available, while the redesigned Portfolio keeps open positions, resolved contracts and trade history under the same account view.
The protocol said it would continue adding liquidity from other mainstream prediction markets as Fortune Markets develops its unified market layer.
