POLYMARKET DIGEST — 17 SEPTEMBER 2026

🔥 News & Announcements

Pyth feed deprecations (Sept 16, 8 PM ET) — three commodity feeds retired:
• WTI Crude Oil (WTIV6/USD, WTIX6/USD): ~30+ September & week-of-Sept-14 markets migrated to CME Group official daily high/low.
• Natural Gas (NGDV6/USD): ~12 weekly NG markets (week of Sept 14) similarly migrated to CME Group NG settlements.

⚠️ Bugs & Issues

• Positions not updating (4+ days): filled orders stuck in UI, not appearing in positions panel. No team response.
• Portfolio value flickering: cash & portfolio balance swinging 40–50%, not reflecting real positions.
• Sort by price missing from positions panel — feature removed or broken, impacts rebalancing.
• Leaderboard broken: monthly weather leaderboard leader has zero weather trades.
• Vance rate stale: UI still shows 3.25% despite Fed hike to 3.50%.
• KYC delay: at least one user waiting 1 month for approval.
• Scam alert: fake "Polymod" account phishing users via DM — confirmed impersonator, not staff.

📋 Clarifications

• El Niño markets (7 markets): "Regional Oceanic Index" corrected to Relative Oceanic Index (RONI) across all 2026–27 El Niño markets.
• Moscow air traffic market: resolution criteria tightened — "temporary restrictions" qualify as suspension; airports "accepting/dispatching flights in agreement with authorities" do not independently qualify.

⚡ Disputes

"Rebate gate" — ongoing (~24+ days, no resolution): Polymarket secretly granted 80% taker fee rebates to select traders. Staff (keaton, Suhail) previously denied preferential treatment publicly. Discovered on-chain by community. pmkeaton now admits no proper response given but calls it "not my area of expertise"; Suhail deflecting. Community alleging potential CFTC/MiFID II violations. Users threatening to exit; retail sentiment deteriorating.

LP reward bots flagged: wallets 0x7f9c6ce5... and 0x581ee4cf... suspected of cancel-after-fill exploitation — fixed timestamps, tiny fills, rewards withdrawn ~10 min post-distribution. Taker delay variable also raised from 50 → 150 over past 3 weeks, possibly related.
