Arkham
What ChatGPT, Claude, Gemini & Grok actually say · July 2026
The verdict
Arkham appears in 1 AI-ranked category — best position #5 for onchain analytics platform.
Powerful entity-centric investigation through address attribution, transaction tracing, portfolio views, alerts, and visual fund-flow analysis; particularly useful for following whales, funds, exchanges, and counterparties.
Claude The strongest free entity-level intelligence — deanonymized labels tying addresses to funds, exchanges, market makers, and governments, plus visual tracing and alerting that made it the go-to for following specific actors' flows; at zero cost it delivers a large share of what Nansen charges for.
Where Arkham falls short, per the models
- GPT Attribution is probabilistic and comparatively opaque, making it unsuitable as the sole evidence source for high-stakes research.
- Claude Label accuracy is unaudited and occasionally wrong in high-stakes ways, and it offers little for aggregate/statistical analysis — it's an actor-tracking tool, not a metrics platform.
