0x4abc806c5ea95d61010adcc98efa42fa743f0f2fc4afa2d2b0ac67132d024338 What is Grand Labs?
Grand Labs is a verified Polymarket Builder Program participant whose canonical product surface is not currently identifiable. On the Polymarket Builder leaderboard, Grand Labs ranks #194 by 30-day volume ($632 routed from 2 users) and #225 all-time ($26.3k cumulative from 6 lifetime users) — a tight, low-frequency concentration consistent with proprietary or whale-style routing rather than retail flow. The previously associated URL grandlabs.io was checked and is a generic software-development agency landing page with no Polymarket integration, so it has been rejected as the builder's product surface. A second plausible candidate — 'Grand' (grand.io, @Grand_xyz) marketed as an AI investing platform — surfaced in search but cannot be confirmed as this builder without direct evidence linking it to the builderCode. Founders, funding, team size, launch date, and exact product surface remain unverifiable. The Polymarket-verified status itself is genuine; only the public-facing brand is unidentifiable today.
Grand Labs is a verified participant in the Polymarket Builder Program for which we cannot confirm a production Polymarket-focused website as of May 2026.
Leaderboard data shows Grand Labs ranked #194 by 30-day volume ($632 from 2 active users) and #225 all-time ($26.3k from 6 lifetime users). The concentration pattern — six lifetime wallets for $26k of cumulative volume — is consistent with proprietary or whale-style routing rather than retail product flow.
The grandlabs.io domain auto-assigned in earlier passes was directly verified to be a generic software-development agency landing page with no Polymarket integration, no prediction-market references, and no on-chain product surface. It is rejected as the builder's actual product. A separate 'Grand' project — grand.io, Twitter handle @Grand_xyz, positioned as an AI investing platform — also surfaces in search results, but we could not find direct evidence linking it to this builderCode and the AI-investing pitch doesn't obviously match a Polymarket attribution flow.
The Polymarket-verified status itself is real (✓ on builders.polymarket.com), so Grand Labs is genuinely routing flow through the Builder Program. What is missing is a public-facing brand we can confidently attach to that flow. Founders, funding, team size, launch date, and the exact product surface all remain unverifiable until that brand emerges publicly.
Editorial assessment: legitimate but currently anonymous builder. Not Tier-2; just operating without a public face. We will refresh this profile when more evidence emerges.

How to verify Grand Labs
- On-chain attribution — every Polymarket Builder routes via an order that includes their
builderCode. The hash above is checkable on Polygon against Polymarket's CTF Exchange. - Polymarket's own verification — $Grand Labs carries the official ✓ verified flag in the data API.
- Cross-check Polybot Arena — polybot.arena tracks wallet-level P&L for builder-tagged bots. If a builder claims specific performance, their wallet should be findable there.
- Tier-2 patterns to avoid — we flag builders that match the Tier-2 pattern (no public team, no verifiable claims, recurs across affiliate-SEO listicles). See our /methodology page for the full criteria.
