POLYMARKET DIGEST — 16 SEPTEMBER 2026

⚠️ Bugs & Issues

Multiple ongoing platform problems reported:
— Archived/deleted markets appearing in Active Portfolio with ghost values; toggle to hide them broken (resets itself)
— Open orders not displaying correctly: placed orders invisible, cancelled orders persist
— Apple Pay/card deposits not working
— Profile trading volume mismatches leaderboard stats
— API batch order endpoint timing out; CLOB API blocking Gnosis Safe addresses with "maker address not allowed" error
— WebSocket price_change feed dropping cancellation deltas silently, causing phantom orderbook levels — no sequence number exists to detect gaps client-side. berth6833 confirmed this is a known issue and has requested seq_id support in the next engine
— Order latency spikes reported: p99 hitting 1200ms on 5m crypto markets during volatile moves; sonderwrld shared stats showing POST p90 at 102ms, CANCEL p90 at 68ms
— RTDS streams dropping out regularly

📋 Clarifications

US–Iran ceasefire markets (Sep 4, 7, 11, 18, 30): Rules clarified — pre-creation military actions are not qualifying events; the 14-day ceasefire window starts the day after market creation if no post-creation action has occurred.

Bab el-Mandeb & Strait of Hormuz transit markets: Resolution source formally added as IMF PortWatch transit calls data; unrounded values take precedence over rounded ones.

AI Chatbot Arena 1520 score markets (Sep 30 & Dec 31): Polymarket announced order books were cleared at 7:30 PM ET Sep 15, then issued a resolution clarification: on Sep 2, claude-fable-5.1-max displayed a score of 1523, meeting the 1520 threshold. Rules impose no minimum vote count and do not disqualify scores later revised — markets resolving YES.

⚡ Disputes

Rebate Gate remains the dominant ongoing conflict. Community members (sonderwrld, vader17, kryme69, vilius.u, lochnload2718 and others) are demanding a public post-mortem on secret 80% maker rebate deals given to select accounts — described as tens of thousands of dollars in unfairly distributed advantages. suhailkakar (Polymarket) engaged briefly, stating "a bunch of things are getting finalized" on rebates, acknowledged the taker delay increase as a response to feedback, but dismissed critics as "3–5 people." Community rejected this characterization. vilius.u urged a full honest post-mortem. lochnload2718 called for taking the campaign to Twitter under #POLYREBATEGATE. suhailkakar then went offline, further inflaming the channel.

pinner flagged two addresses (0x7f9c6ce5785b87f31b5e397c8985d7d894829236, 0x581ee4cf297c2a057aed53d928f60f1adf981526) as suspected cancel-after-fill bots generating programmatic fills at fixed timestamps with tiny notionals to avoid detection, withdrawing LP rewards 10 minutes after distribution.

Community also pressing for a combined US/international order book — kryme69 raised it directly; suhailkakar said it is not current priority (focus is DeFi web experience & trading performance). A tweet from @caronpolymarket hinted it may be coming, but no official confirmation.
