The Polymarket-focused explorer surfaces wallet positions, trade history, and leaderboards, and now supports Protocol V2
Prediction markets have always run on a quiet question: who is actually winning? Orbscan, a dedicated explorer and analytics platform for Polymarket, now lets users answer it by tracking wallet positions, profits and losses, and full trade history.
The data is available two ways: through a public explorer and through an API built for developers.
What Orbscan actually shows
Orbscan launched publicly in mid-September 2026. Its core pitch is wallet-level visibility into Polymarket activity, the kind of detail that previously required digging through raw blockchain records.
Users can pull up any wallet and see its open positions, its performance, and its trading record. Performance is split into realized and unrealized PnL, which separates profits already locked in from gains that still exist only on paper.
The platform also runs leaderboards. At launch, those boards featured top traders whose 30-day PnL topped $2.9M.
There is also a live activity feed. It displays individual trades across Polymarket events in near real time, so users can watch money move on elections, games, and crypto bets as it happens.
The API and the Etherscan connection
For builders, the bigger story may be the API. Orbscan offers endpoints covering open and closed positions, trader activity, and order-book history.
Access currently runs through an API key waitlist. Retail traders can use the explorer for things like strategy simulation, while developers get programmatic access once they clear the queue.
The platform draws on the indexing expertise of the Etherscan team, according to the research findings.
Keeping pace with Polymarket V2
On November 2, 2026, the platform announced full support for Polymarket Protocol V2, which arrived as Polymarket shifted to a new market architecture.
V2 introduces a unified ERC-1155 position contract and modular oracles, and it phases out the Gnosis Conditional Tokens Framework that Polymarket previously relied on.
Orbscan says it indexed both the legacy and V2 contracts, so users can follow positions across the transition. Its API endpoints were updated for V2 as well.
Why prediction market data matters now
Polymarket operates on Polygon and has reported growing volumes across categories including politics, sports, and crypto. Because Polymarket runs on-chain, all of this activity was technically public already, though public and usable are two very different things.
What this means for traders and builders
For developers, the API lowers the cost of building on top of Polymarket data. Dashboards, alerts, research tools, and trading bots all start with clean data, and Orbscan is positioning itself as the source that already did the cleaning.
The API waitlist means builder access is still gated, and the depth of what Orbscan exposes will likely shape how much third-party tooling emerges around it.
