Official summary from @PolymarketDevs for the week of August 10, 2026. Several changes directly affect bot developers and active traders.
1. Volume-Based Rate Limits (Now Live in Production)
Per-signer volume-based rate limit tiers are live and already reducing spam traffic.
- Limits scale with trailing trading volume
- Higher volume unlocks higher order/cancel throughput
- Separate from IP-based Cloudflare limits
- Docs: Trading Rate Limits
Bot impact:
Respect Poly-RateLimit-Warning and Retry-After headers. Batch where possible. Pure spam or aggressive testing without real volume will hit throttling faster than before.
2. TWAP Change for 5-Minute Crypto Markets
5-minute crypto markets moved from a 30-second to a 60-second Chainlink TWAP lookback.
- Live on 5m markets deployed since August 14, 2026
- Both the opening reference (price-to-beat) and final settlement now use the 60s window
- Smoother series → less last-second wick influence, but also slower-reacting fair value
Bot impact:
Any system still anchored to the old 30s feed is now misaligned with settlement. Signal models, open-price pinning, resolution scoring, and scratch thresholds all need to target the 60s series.
3. Passkeys
Passkey login is live for Magic wallet users (email and social logins). Improves login UX and reduces reliance on traditional seed/password flows for those users.
4. Perps Improvements
- ADL fills are now flagged in trade history; both sides are notified
- New mark-price history endpoint
- Mobile web trading and margin control improvements
- Share cards scheduled for early next week
The ADL visibility change is especially useful for auditability — forced deleverages are no longer opaque balance changes.
5. Combos
- Odds visible while logged out
- Finished games hidden
- Geopolitics combo markets in preparation for next week
Continues the expansion of multi-leg (RFQ-based) products beyond pure sports.
6. Data API & Infrastructure
- New
/v1/approvalsendpoint - Faster native serving for positions and PnL
- Fixes for resolved markets incorrectly showing as open
- PnL price bug fixed
- Price-history moved onto its new serving layer (after last week’s slowdown)
7. Gamma & Bridge
- Clearer 503 responses
- Graceful search degradation
- Keyset pagination on comments
- Bridge API pagination is live; docs updated
Practical Takeaways for Bot Builders
| Change | Action Required |
|---|---|
| Volume rate limits | Implement proper backoff + volume awareness |
| 5m TWAP 30s → 60s | Switch feed, re-pin open reference, recalibrate model |
| Data API fixes | Re-test position/PnL reconciliation paths |
| Bridge pagination | Update any code assuming unpaginated responses |
| Perps ADL flagging | Surface ADL events in your trade logs |
Bottom Line
Two changes dominate for automated systems this week:
- Rate limits are now volume-gated in production — spam is being throttled.
- 5-minute crypto settlement fully moved to 60s Chainlink TWAP — any remaining 30s assumptions are wrong.
Everything else (Data API fixes, Combos UX, Perps transparency, Passkeys) improves platform quality but is secondary to those two operational realities.
Check the official docs and @PolymarketDevs for the latest endpoint and limit details — they continue to evolve.
