Tonkeeper Adds Predict with Polymarket to Built-In Browser
Tonkeeper announced the Browser integration as the 2026 FIFA World Cup entered its semi-final stage. The two semi-final matches were scheduled for July 14 and 15.
Users can open Tonkeeper, navigate to the Browser section, and select Predict with Polymarket. From there, they can choose an event and buy a position representing a possible outcome.
Positions Can Be Sold Before an Event Ends
Predict operates as a peer-to-peer prediction market. Prices depend on trading activity instead of fixed odds set by a conventional bookmaker. These prices can be interpreted as the market’s current estimate of an outcome’s probability.
It is not necessary to hold the position until the market resolves. Once a market is resolved, winning shares are redeemable for $1 each, while losing shares become worthless. Users may sell before resolution, although execution depends on available liquidity.
Polymarket uses this approach across sports, politics, crypto, technology, and cultural events. The platform sorts its active contracts into an array of topics where the prices change depending on what outcome shares users buy and sell.
User-Facing Payment Flow
Tonkeeper users fund the service with USDT on TON and can receive withdrawn funds back into their connected TON wallet. Behind the interface, Omniston handles the cross-chain movement between TON and the EVM-compatible environment used by Polymarket.
Predict first launched as a Telegram-native service that gave TON users access to Polymarket markets. Users can connect a TON wallet and open positions without manually setting up an additional EVM-compatible wallet or handling a bridge and network-specific gas tokens. Through Tonkeeper’s built-in Browser, the same service is now accessible directly from the wallet interface.
Availability Remains Restricted by Jurisdiction
Tonkeeper’s announcement stated that the communication was not intended for users in the United States, the United Kingdom, or other restricted regions. Availability depends on the user’s physical location and the applicable platform restrictions.
Users may lose the full amount committed to a position. Market prices reflect trading activity and do not guarantee that an outcome will occur.
The integration gives Tonkeeper another use case for USDT on TON while placing prediction markets alongside the other decentralized applications available through its Browser.
