0xInsider: what it does, what it costs, where it stops

What it does

Thirty boards cover sports and esports, from the NFL and the Premier League to CS2 and League of Legends. Each is free to read; the full sharp-money read on a game needs Pro.

Pro adds the live feed of large Polymarket sports trades that clear the site's size thresholds, each with the wallet behind it, plus funding tracing (confirmed pUSD movements into tracked wallets, linked to transactions), suspicious-trade flags for unusual size, clusters and new wallets, and per-wallet analytics including P&L, Sharpe, Sortino, VaR, drawdown and category splits.

• Follow up to 50 traders or categories with alerts, plus daily and weekly digests
• New-wallet filter: wallets first active in the last 30 days
• Daily, weekly and monthly sharp-money and resolution reports
• Datasets and JSON exports; a developer API and MCP endpoint included in Pro

Pricing

One paid plan. Weekly $25, monthly $99, annual $899, which the site presents as $75 per month and a 24.3% saving. Cancel any time; access follows Stripe confirmation.

Venues and data

Polymarket only, and within it sports and esports markets. The site is explicit that a grade is a record, not a prediction, and that a flag is a lead, not a verdict.

Where it falls short

If you trade politics, macro or crypto markets there is nothing here for you, and there is no Kalshi.

The entry price is high for a single-venue, single-vertical tool: $99 per month against $9 to $30 for the general trackers on this site. The weekly plan exists for trying it during one season.

Who should use it

Sports and esports bettors on Polymarket who want to fade or follow graded wallets rather than the crowd, and builders who want those grades in code through the API or MCP.
