Blockchain intelligence firm Arkham has launched a comprehensive analytics suite tailored for prediction markets, bringing its powerful deanonymization engine to a sector that just recorded over $74 billion in quarterly volume. The new tool, announced on May 7, aggregates data from 3.5 billion address labels and 800,000 verified entities accumulated since 2022 to offer unprecedented transparency into betting platforms like Polymarket and Kalshi.
The suite includes a PNL-ranked leaderboard of top traders, allowing users to inspect any participant’s full trading history, open positions, ROI, win rate, and performance graphs. A live trade tape streams every transaction across the entire prediction market ecosystem, filterable by categories such as politics, sports, and crypto. Arkham’s identity layer cross-references these wallets with its broader on-chain tracking—meaning a user can see if the same address that just moved $50 million in Bitcoin is also holding a massive election contract.
In practice, the tool highlighted trader “Theo4,” who boasts a lifetime PNL of $22 million and an 88.9% win rate, the bulk of which came from a single $14.4 million win on predicting Trump's popular vote in 2024. The launch follows Arkham’s recent expansion into decentralized trading on Solana and cements its comparison to a Bloomberg Terminal for crypto. With prediction market open interest hitting $1.11 billion on May 1 and Kalshi overtaking Polymarket in taker volume, Arkham is positioning itself as the essential intelligence layer.
