Why the Chart Looks Wrong After a Market Closes
The chart isn't lying — it's showing the wrong thing. Here's why post-close charts diverge from settlement, and how to confirm your payout is correct.
✅ Short Answer
Post-close charts often display the last traded price, not the final resolved price. Your payout is calculated from the settlement oracle — an entirely separate data source. A chart showing 60¢ after a market resolved Yes is a display artifact, not a payout error.
Two Things That Look the Same But Aren't
📉 What the Chart Shows
The last traded price — sometimes hours stale by the time the market resolves
Candlestick/line data freezes at the last market activity
May display ~60¢ even if the market officially resolved Yes (100¢)
⚠️ This is a display artifact — not authoritative
💰 What Determines Your Payout
The settlement oracle — the verified real-world resolution source specified in the market rules
Your account balance update — processed by the settlement engine
Fully independent of chart display state or cached trade data
✅ This is the authoritative source for your money
Why This Happens
Trading stops before official resolution
Prediction markets often stop accepting new orders before the final resolution event occurs. The chart freezes at the last traded price while the platform waits for the real-world outcome to be confirmed.
Chart data and settlement data are separate pipelines
The chart pulls from a trade history database. Your payout comes from a settlement engine that reads from the oracle resolution source. These two systems update independently — the settlement engine is authoritative.
Display caches can lag minutes to hours
Even after a market resolves, chart display layers may cache the old price for minutes to hours depending on the platform's CDN and refresh cycle. Your balance update happens faster than the chart corrects.
Is Your Payout Still Correct?
Did the market officially resolve?
Check the market page for a "Resolved" status label or settlement note — not the chart price.
Did your balance update?
Check your account's transaction history or portfolio balance. The settlement engine processes payouts separately from the chart display.
✅ Balance updated correctly? — Chart discrepancy is cosmetic. You're fine.
⏳ Balance still pending under 24h? — Normal settlement window, wait.
🔴 Balance wrong after 48h+? — Go to Step 3.

Platform Chart Behavior After Close
How each major platform handles the gap between trading end and official settlement.
Charts display last-traded price data from the CLOB (Central Limit Order Book) order flow. Post-close, the chart can freeze well below the resolution price if late trading volume was sparse.
Settlement comes from UMA oracle resolution — a separate system that reads from the specified real-world data source.
As a CFTC-regulated exchange, Kalshi maintains separate systems for trade chart history and official settlement. Settlement is logged as a CFTC-reportable event.
Your balance reflects the settlement outcome. Chart data may lag behind the official resolution notice depending on market activity near close.
When to Actually Worry
| Signal | Situation | Verdict | Action |
|---|---|---|---|
| 🟢 | Chart shows wrong price, but your balance updated correctly | Display artifact — you're fine | No action needed |
| 🟡 | Chart wrong, balance still showing pending (under 24 hours) | Normal settlement window | Wait for the platform's standard settlement processing time |
| 🔴 | Chart wrong AND balance hasn't updated after 48+ hours | Escalate to support | Open a support ticket with the market URL and resolution date |
