Orbscan, an analytics platform for the prediction market Polymarket, now allows users to track wallet positions, trade history, and profit and loss metrics. The service provides data through a public explorer and an API for developers, which is currently accessible via a waitlist.
Launched in mid-September 2026, the platform offers visibility into both realized and unrealized gains. At its debut, leaderboards highlighted top traders with 30-day profits exceeding $2.9 million. A live feed also enables real-time monitoring of trades across various market events.
The platform utilizes indexing expertise from the Etherscan team. On November 2, 2026, Orbscan added full support for Polymarket Protocol V2, which transitioned to a unified ERC-1155 position contract and modular oracles, replacing the previous Gnosis Conditional Tokens Framework.
Orbscan has indexed both legacy and V2 contracts to ensure continuity in tracking. The API provides endpoints for open and closed positions, order-book history, and trader activity, aiming to simplify data access for developers building dashboards, research tools, and trading bots.
