Every trader on Polymarket has a track record - we show it to you.' It sits inside a much larger on-chain intelligence platform that also covers token flows, exchange balances, and other chains. arkm.com, its predictions page, its home page, and its pricing page all returned an HTTP 403 Cloudflare challenge to every fetch attempted for this review on 2026-09-17. The facts here come from Arkham's other public surfaces: its announcements blog, its API documentation, and its sitemaps. ## Wallet identity and fund tracing Arkham's core differentiator is identity, not just activity. It says it has built 'the largest catalogue of deanonymized on-chain traders on Earth, with over 3.5 billion address labels and 800,000 Verified Arkham entities,' and its Visualizer and Tracer tools map a wallet's transactions across every address it controls, on any chain Arkham covers. Twenty-plus published Polymarket tags include potential-insider, fresh-wallet, resolution-sniper, bot, market-maker, early-mover, and tags for soccer, NFL, NHL, NBA, and MLB traders specifically. 0xinsider tracks a wallet by its Polymarket address. It does not attempt to link that address to a real-world identity, and it publishes no behavior-tag taxonomy comparable to Arkham's. **Verdict (Arkham):** Real identity and fund-flow tracing, at a scale 0xinsider does not attempt. ## Trader scoring: an Elo rating against a published grade Arkham's Elo-style rating, launched 2026-06-29, ranks 'traders based on prediction accuracy,' rewards a correct call at longer odds more than one at short odds, and by its own description 'does not take bet sizing into account.' The exact formula (its K-factor, its starting rating) is not published. Arkham's own figures for the top-ranked trader (a 64.3% win rate over 2,644 bets, an Elo of 2389) differ from a 66.1% win-rate figure attributed to the same wallet in third-party press coverage, which appears to reflect a different snapshot. 0xinsider's grade is about 95% realized (banked) profit, with eligibility floors that do real work: anything above a C needs verified net-positive realized profit, and the top three grades also need a real resolved-market count and a survivable worst drawdown. Every graded wallet also carries the full risk-metric set: Sharpe, Sortino, drawdown, expectancy, VaR, and Kelly fraction, none of which appear in Arkham's published wallet-summary fields. **Verdict (0xinsider):** A published floor and a full risk-metric set, against an Elo rating that ignores size. ## Alerts and detection Arkham's alerts fire by email, Telegram, and webhook, customizable by address, entity, position size, and token type, on top of the behavior tags above. Its API also exposes order-book and top-holder endpoints for individual Polymarket markets. 0xinsider publishes suspicious trades as statistical flags with the wallet, market, and timestamp attached, and today's alerts run by email on the wallets and markets a reader names. **Verdict (Arkham):** More channels, and a published tag taxonomy underneath them. ## What each one costs Arkham's own web-app pricing could not be checked behind the Cloudflare challenge. Its API is usage-based, described as 'custom-built' and starting at $100/mo in credits, with individual Polymarket endpoints costing 1 to 2 credits each, plus an x402 pay-per-request option at $0.20 per credit. 0xinsider's free account includes the full trader leaderboard, full trader profiles with Insights, the previous day's large trades, and one Pick of the Day. Pro adds the live large-trade feed, custom alerts, suspicious trades, the REST API and MCP server, and in-game position changes while a game is live. Current plans are on the [pricing page](https://0xinsider.com/pricing). ## Which one to use Use Arkham if the job is identity: linking a Polymarket wallet to a real-world entity, tracing its fund flows across chains, or filtering by a published behavior tag. Use 0xinsider if the job is a sports and esports grade with a published, floor-gated method and a full risk-metric set, reachable without a bot-verification challenge. ## Best for 0xinsider - Traders who want a published, floor-gated grade with a full risk-metric set - Sports and esports traders who want per-game boards and in-play tracking - Readers who want a hosted MCP server without writing their own script ## Best for Arkham - Readers who want a wallet linked to a real-world identity or entity, not just an address - Anyone who wants to trace a trader's fund flows across multiple chains - Traders who want alerts by email, Telegram, and webhook on named addresses or entities ## 0xinsider: Pros & Cons **Pros** - Published grade with eligibility floors, not an Elo rating that ignores position size - Full risk-metric set per graded wallet - Sports and esports focus with per-game boards - Hosted MCP server; no DIY script required **Cons** - No wallet deanonymization or cross-chain fund tracing - Fewer alert channels: email only today - No published behavior-tag taxonomy comparable to Arkham's ## Arkham: Pros & Cons **Pros** - Deanonymizes wallets and traces fund flows across chains (its own claim: 3.5B+ labels, 800,000+ verified entities) - 20+ published Polymarket behavior tags, including per-sport tags - Alerts by email, Telegram, and webhook - Sits inside a broader on-chain intelligence platform **Cons** - Its Elo rating explicitly does not weight position size - The exact Elo formula (K-factor, starting rating) is not published - arkm.com returned a bot-verification challenge to every fetch on 2026-09-17, so its web-app pricing and current interface could not be checked directly - No hosted MCP server; the published path is a DIY script generated with an AI assistant
