0xinsider covers Polymarket only since September 8, 2026. This post describes a feature as it shipped on its date, some of it built for a venue 0xinsider no longer covers. Read the retirement note
A trader drops $400K on Yes. The price moves 19 cents in under an hour. You find out six hours later on Twitter, in a screenshot with no context.
Who was that? What's their record? Was it conviction backed by months of research, or a mistake that's about to unwind? Nobody can tell you. By the time you see the tweet, the edge is already gone.
That information gap costs real money. Today, it closes. 0xinsider is now open to everyone.
Large Polymarket trades in one feed
0xinsider pulls large Polymarket trades into one place, each with its wallet context. We show what we ingest, not a claim to every exchange event.
Each row shows the provider facts for that record and links to a tracked wallet profile.
Skill or luck? Now you can tell.
Polymarket ranks traders by profit. A trader who hit one lucky $5M bet outranks someone who's been consistently profitable across 200 markets. No risk adjustment. No strategy context.
It does not answer the only question that matters when you see a large trade: should I pay attention to this trader, or ignore them?
Tracked Polymarket wallets with sufficient history can receive a cohort-relative grade. The grade summarizes observed results under the current model; it does not predict future performance. The earlier cohort charts and benchmark figures were authored without a retained dated query, so they have been withdrawn.
Context a single-trade alert can miss
A trade alert bot tells you someone bought $200K of Yes. End of message. No history, no track record. Was this trader's last five bets profitable, or did they blow up three times this month? The bot can't tell you.
When a Polymarket trade resolves to a tracked wallet with sufficient history, the row can link to its grade, P&L, strategy, and risk context.
A sequence of individually small orders may stay below a single-trade alert threshold while building a material aggregate position. Large Positions groups supported tracked position records so readers can inspect that accumulation with its stated freshness and coverage.
Historical leaderboard figures withdrawn
An earlier version displayed named March 2026 leaderboard figures without retaining the query artifact needed to reproduce that snapshot. Those names, grades, P&L totals, win rates, and cohort counts have been withdrawn. Current leaderboard values should be read from the live product with its current model and freshness context.
Start free. Upgrade when it clicks.
The free tier has no time limit or credit-card requirement. It exposes the currently supported public leaderboard and delayed terminal preview; availability and record counts are determined by the live product rather than this dated announcement.
Pro ($99/mo, or $891/yr paid upfront, equivalent to $74.25/mo) removes the free-tier delay and adds diagnostic signal scores, Insider Radar context, alerts, tracked positions, exports, and analytics. Scores organize evidence; they do not predict outcomes or guarantee returns.
Plans
We were manually tracking trades across two exchanges. That's gone now.
