Common Polymarket issues

  • Wallet won't fund or withdraw

    Polymarket funding goes through Polygon. Bridge congestion, missing MATIC for gas, or a paused fiat on-ramp partner can all stall deposits while the CLOB itself is fine.

  • Orders not filling on a hot market

    Spreads widen dramatically around live events. Use limit orders inside the visible spread instead of market orders when the book is thin.

  • Site loads but trading is greyed out

    Usually a geofence trip — a VPN or non-US-permitted region was detected. Polymarket blocks US-based users from trading by policy.

Background

Polymarket was founded by Shayne Coplan in 2020 and rose to mainstream attention during the 2024 US election cycle, where its odds were quoted by major news outlets. The platform settled tens of billions of dollars of notional volume on the election alone and remains the largest non-US prediction market by volume.

Frequently asked

How do I know if Polymarket is down?
Check real-time response status for Polymarket's CLOB API and frontend endpoints. If orders fail to place or balances do not refresh, the platform may be undergoing scheduled maintenance or experiencing Polygon network congestion.
Why is Polymarket not loading or failing transactions?
Polymarket transaction failures typically stem from RPC node latency, Polygon network congestion, insufficient gas balances, or temporary maintenance on Polymarket's relayer and trading APIs.
Where can I find official Polymarket status updates?
Polymarket status updates are broadcast via official Discord announcements, their status page, and real-time client-side monitoring tools like kalshi.health.
Why can't I access Polymarket in the US?
Polymarket restricts US residents from trading due to CFTC regulatory settlement compliance. Geoblocking may prevent US IP addresses from accessing active order books.
What should I do if Polymarket is unreachable?
Clear your browser cache, check Polygon network status, test alternative DNS providers, or verify whether scheduled API maintenance is underway via their official status alerts.
How can I check if Polymarket is down?
Check real-time status on kalshi.health, which pings Polymarket's CLOB API and front-end endpoints directly from your browser to detect localized or exchange-wide outages.
Why is Polymarket not loading or connecting to my wallet?
Wallet connection issues are typically caused by RPC node latency, browser extension conflicts, or Polygon network congestion rather than a core exchange outage.
What is the difference between Polymarket API and front-end downtime?
Polymarket's web interface may experience CDN issues while backend CLOB order books continue processing limit orders via direct API connections.
Why can't I place a trade on Polymarket?
Trading issues are usually caused by CLOB API degradation, RPC node problems on Polygon, or your wallet not being funded with MATIC for gas.
