Arkham Prediction Markets Overview
Arkham's prediction markets hub lives inside the Intel platform at intel.arkm.com/predictions and gives traders a clear view of who is buying and selling shares on Polymarket and similar venues. It pulls from a database of over 3.5 billion address labels and 800,000 verified entities to connect onchain trades to real-world accounts, so you can see which wallets belong to known participants and how they are performing.
The tool is built for anyone who takes prediction market trading seriously. Professional bettors can sort a live feed of top accounts by lifetime profit and loss, then drill into any profile to see every open and closed position, entry and exit prices, win rates, and return on investment figures. Researchers and institutional observers get actual capital flow data rather than polls or sentiment surveys. Developers can pull the same data through the Arkham API to build automated alerts or custom dashboards around whale activity.
At the core is a real-time trade tape that scrolls every buy and sell across tracked markets. You can filter by category such as politics, sports, or crypto, or sort by who currently holds yes or no shares on a given event. Clicking any labeled address overlays that trader's full entry and exit history directly onto the market's price chart, so you see the timing of their moves in context with price action. From the same view, you can follow links into their broader wallet history and portfolio flows without switching platforms.
What separates this from a generic blockchain explorer is the entity labeling layer. Most onchain tools show raw addresses. Arkham attributes those addresses to specific people or organizations, which means the prediction market analytics here come with identity context attached. You are not just watching anonymous capital move. You are watching known participants take positions, and you can track their full history across markets and time.
Access is open to all Arkham users, and the alert system connects to the existing Intel workflow, so you can set notifications for specific traders or markets and review everything in one place.

Honestly, this is one of the best things Arkham has released in recent months. Having all the data integrated into a single interface has always been Arkham's strength. Keep up the good work!

prediction markets + onchain intel is a crazy combo congrats! ... This kind of integration finally gives serious traders the visibility they need to track smart money moves across events without jumping between platforms. The combo of PNL leaderboards and full wallet history is exactly what the space has been missing.

Arkham just added the who. We track the what and the when. The full picture is finally coming together. ... Being able to overlay top traders' entries and exits directly on price action while seeing their broader verified activity elevates the entire analytics game for anyone serious about sports, politics, or crypto event betting.

Find top-performing wallets on Robinhood Chain with the Arkham API.
I asked Claude to scan CASHCAT holders and find the top traders on Robinhood. This is Trader 0x521, who achieved a 24,500x on CASHCAT.
He bought $53 of CASHCAT, 18 minutes after launch - and turned it into $1.29 MILLION today.
2 more in this thread
Trader 0x521 was incredibly early to Robinhood Chain. He bought 0.02 ETH of CASHCAT on the day of launch, securing 1.9% of supply when CASHCAT was at only $2.8K market cap.
He sold the majority of his tokens - over 1% supply - in early July, securing $436K. However, he’s still holding $728K of CASHCAT, which is approaching its ATH after a listing on Robinhood.
Will he keep holding?
