Polymarket users were unable to access the prediction platform on Tuesday after a widespread Cloudflare outage disrupted multiple websites and crypto services across the U.S.
At the time of updating the copy at 3:12 PM ET, the services appear to function normal.
During the downtime, users were greeted with the message, "Polymarket is down... Oops...we didn't forecast this." The site advised users to reload the page.
Downdetector showed a sharp spike in Polymarket-related problem reports, with 86% of users flagging website issues, 11% reporting login troubles, and 3% noting "website test not starting." The surge in reports was significantly above normal levels, triggering Downdetector's incident alert.
While Polymarket has not yet issued a formal statement, user reports and network telemetry indicate the outage is linked to a major Cloudflare disruption affecting routing and content delivery across multiple regions. Cloudflare outages often impact large swaths of the internet, given the company's role in DNS, CDN, and edge-network infrastructure.
