Convexly vs Arkham for prediction markets
Different tools for different jobs. Arkham is on-chain intelligence that tells you who a wallet is. Convexly is a statistical audit layer for one narrow question: does a Polymarket wallet's record reflect skill or luck?
Side by side
| Dimension | Arkham | Convexly |
|---|---|---|
| Primary job | On-chain intelligence and entity attribution: linking wallets to real-world entities across many chains | Statistical audit of prediction-market wallet skill: does a record separate from chance |
| Core question | Who controls this wallet, and what is it doing on-chain | Does this Polymarket wallet's resolved record reflect skill or luck |
| Coverage | Many chains and asset types; a broad entity-attribution universe | Polymarket prediction markets: one venue, one narrow question |
| What a wallet read means | An identity or entity label summarizing who is behind observed on-chain behavior | A four-state statistical read (skilled / not separable from chance / insufficient / flagged), each state with a frozen threshold |
| Uncertainty | Not the product's framing | Every skill read and realized entry edge carries a bootstrap 95 percent interval plus its resolved-position count; a point estimate is never shown alone |
| Multiple-testing correction | Not the product's framing | Benjamini-Hochberg FDR correction across every cohort screen (primary q = 0.10, with q = 0.05 / 0.20 sensitivity in enterprise work) |
| Chance baseline | Not the product's framing | Size-matched negative control: 500 seeded random cohorts run through the identical test in enterprise cohort work |
| Negative results | Not part of the product | Published, including against its own cohort: 0 of 35 testable top-50 wallets cleared the corrected bar (2026-06-09 scan) |
| Best for | Learning who is behind a wallet, across chains and tokens | Deciding whether a Polymarket record is evidence of skill before acting on it |
"Not the product's framing" is descriptive, not a criticism: an entity-attribution platform and a narrow skill-audit layer are optimizing different things.
What Arkham does well
Arkham's strength is attribution. It links wallets to real-world entities across many chains and asset types, and turns raw on-chain flow into dashboards and alerts a researcher can act on quickly. If your question is "who is behind this wallet, and what is that entity doing across the chain", that is the job Arkham is built for. For a Polymarket wallet, Arkham can tell you the identity side of the picture.
What Convexly does differently
Convexly does not try to identify anyone. It applies audit-grade statistics to one domain: prediction-market wallet skill on Polymarket, with the methodology set out in the published Edge Score methodology paper. Concretely:
- A four-state skill read (skilled / not separable from chance / insufficient / flagged) instead of a raw PnL rank, with every state gated by a frozen threshold.
- Every read carries a bootstrap 95 percent interval, and the free analyzer also reports realized entry edge, where each estimate travels with its 95 percent confidence interval and the count of resolved positions it is computed on. A bare number is never shown.
- Cohort screens apply a Benjamini-Hochberg false-discovery-rate correction, and enterprise cohort work is anchored by a size-matched negative control of 500 seeded random draws.
- Nulls are published, including against Convexly's own board: in the frozen 2026-06-09 scan, 0 of the 35 testable wallets in the published top-50 cohort cleared the corrected bar (full table).
- Methods are frozen and version-controlled, and follow-up test designs are filed in public registries before the analyses run, as a standing practice documented on the research index.
Which one for which job
Learning who is behind a wallet, or following an entity's activity across chains and tokens: Arkham. Deciding whether a specific Polymarket record is evidence of skill before you act on it, including before you copy it: Convexly. Identity and skill-vs-luck are complementary halves of the same question, and the honest answer for many desks is both.
