0x221b6a7ce5913b8162f55b8195d96879a9a8f9aff257e8dc1da7862272bb7746 What is Predex.dev?
Predex.dev is a Prediction Tool for Polymarket that holds polymarketVerified=true status on builders.polymarket.com under builder code 0x221b6a7…7746 but maintains an extremely minimal public web surface as of May 2026 — the predex.dev homepage returns the single word 'Predex' with no further product description, team listing or social links. The builder code has routed substantial volume: $1.61M in the trailing month from 167 monthly active users (rank #29 monthly) and $5.82M cumulatively from 484 traders (rank #37 all-time), which puts Predex.dev solidly in the mid-tier of active Polymarket builders by traction. Note: a separately funded AI-prediction-market called PredX (predx.ai), backed by Penrose Tech and Malana Ventures, is a distinct project at a different domain and should not be conflated with this predex.dev builder until a direct link is established.
Predex.dev is a Polymarket-verified builder whose homepage at predex.dev (which 301-redirects to www.predex.dev) renders only the single word 'Predex' as of May 2026 — there is no public product description, team page, social-link section, pricing tier, documentation site, or About content reachable from the root URL.
The builder code 0x221b6a7…7746 has nonetheless routed meaningful volume on Polymarket: $1.61M of trades in the trailing month from 167 monthly active users (rank #29 on the monthly leaderboard), and $5.82M cumulatively across 484 unique traders (rank #37 all-time). That MAU count is high enough to suggest a real product behind the builder code — likely an embedded trading widget or a Polymarket-routing application — rather than a single-trader proxy.
A separately documented prediction-market project called PredX (predx.ai), founded in 2023 and led by CEO Rein Y Wu, raised a $500k pre-seed in February 2024 led by Penrose Tech with participation from Malana Ventures at a reported $20M post-money valuation. PredX runs on the SEI blockchain rather than Polygon and is positioned as an AI-driven multichain prediction market, not as a Polymarket builder. There is no public source linking predex.dev to the predx.ai team, and the two should be treated as distinct projects unless a direct connection surfaces.
Until Predex.dev publishes an About page, social handles, or third-party coverage that explicitly maps the builder code to a named team, this entry remains in a verified-traction-but-unverified-identity state.
