POLYMARKET DIGEST — 18 SEPTEMBER 2026

⚠️ Bugs & Issues

Redeem broken — multiple users reported inability to redeem winning positions for 12+ hours. ak504111 confirmed it was being investigated; resolved around 11:20 UTC.

Data API v2 — redeem endpoint not yet implemented in the new API. 0xdanzu confirmed it's being reintroduced, ETA unknown.

LP rewards returning 0% — adam22234 reported earning 0 rewards across multiple markets despite meeting criteria. Unresolved.

CLOB DeadlineExceeded errors on FAK orders (context deadline exceeded 5552ms) — reported by miraacook, confirmed as an intermittent known issue by berth6833.

Stale CLOB order book data — sharkhunterr reported certain markets showing stale odds via CLOB while the UI updates normally.

Referral links — imstillrich reported referral links showing as "expired" despite being used successfully for signups, with no bonus credited.

🔥 News & Announcements

Zero fees on NFL & College Football this weekend (Sept 19–20). sharkhunterr confirmed the promotion. hipp74 noted taker fees still appear on third-party sites — unclear if it's a rebate or a direct fee waiver not yet reflected in the Gamma API.

Taker delay on crypto markets reduced to 150ms (changelog stated 50ms, but blunkoed corrected it to 150ms), down from 250ms. Change took effect August 17.

Builder channel restructured — displaysonx announced builder discussion is consolidating into a new channel; old channel preserved as read-only archive.

Polymarket CEO shayne_coplan posted on X acknowledging degraded onchain product performance, stating the team is "working behind the scenes to unify the products." Community reaction was skeptical — berth6833: "after 6 months he finally heard about the frustration."

⚡ Disputes

80% rebate controversy ongoing. Multiple dev-channel regulars (lochnload2718, blunkoed, tehnoobkiddo) are appending disclaimers to every message, warning that select market makers reportedly receive up to 80% fee rebates with no public disclosure of eligibility. richlb_predict noted the 80% rebate was reportedly paused; blunkoed questioned whether it was truly paused or simply moved off-chain. lochnload2718 warned that if community criticism is suppressed on Discord, they will escalate to Twitter.

Co-location KYC — blunkoed clarified that even after KYC approval, co-location doesn't provide meaningful latency improvement because orders still route through Cloudflare in a separate DC, with an additional wallet check adding latency. Dublin reportedly performs comparably or better. KYC approval times range from 1 week to 6 months.
