Daily digest from Polymarket & UMA Discord. Disputes, bugs, clarifications, announcements.















Polymarket weather refund crisis, May 17-20 🌡 Timeline May 17: Jakarta temperature markets manipulated by new accounts (34°C posted at 1:30 AM vs actual 27°C). Traders lost $400 to $30k. Complaints ignored for weeks. Seoul markets lost resolution tabs. May 18: Oracle broke. Wrong brackets resolved in Miami, Mexico City, Seoul, Hong Kong. London resolved at 15°C, actual high 16°C. All temperature markets archived, positions vanished from UI. Refunds promised in 10 business days. May 19: 50+ cities archived globally. Refund window cut to 7-10 days. May 20: First refund batch ran on ~2k archived markets. Botched. Root cause 🔧 Polymarket silently changed the batch price request format for UmaCtfAdapter without notifying UMA or third-party tooling. Indexes got mismapped, frontend wired markets to the wrong on-chain contracts, and resolutions went into the wrong brackets. On top of that, Weather Underground dropped data points, and missing data defaulted markets to the minimum temperature bracket. Two independent failures stacked. Refund reality 💸 Users are getting 2-10% of expected amounts. Some users with confirmed positions got nothing. May 17 markets for Seattle, Los Angeles, Toronto, and NYC are missing from the payout list entirely. No official site-wide statement. CFTC complaints are already being filed over the communication chaos. What to expect ⏳ Official window: 7-10 business days from the May 18 archive, so a second batch should land between May 28 and June 1. No guarantee it closes the gaps from batch one. If your position is missing: save the tx hash and a portfolio screenshot, file a ticket with the exact market id, and log the timestamp. Collateral damage NBA and cricket markets briefly disappeared overnight on May 20. Sponsored rewards are not showing. Auto-redeem is broken for winning positions above $1. Jakarta was officially discontinued for manipulation, yet Lagos got pulled and Jakarta is still live. No explanation. Daily digest of the Polymarket and UMA Discord channels: @predictdigest
