Impact analysis
The confirmed operational change is to how KuCoin Margin computes its spot index. The source states the upgrade starts October 8, 2026, proceeds per coin, and should be fully migrated by October 12. For BTCUSDT, the index price becomes a weighted combination of spot prices from five named exchanges, with outlier prices beyond 5% of the median adjusted to 1.05x or 0.95x the median, and weights derived from trading volume, turnover, liquidity, and price stability. The source explicitly says trading and assets will not be affected during the upgrade. It does not state which other coins are included, the exact per-coin schedule, or any change to margin requirements, liquidation logic, or fees. Users who rely on the index can consult the Index Price Page and the detailed Index Calculation Rules referenced in the announcement.
What the announcement does not say
The source does not disclose the full list of coins covered, the exact per-coin rollout schedule, the specific weights assigned to each exchange, or whether margin parameters, liquidation rules, or fees change. It also does not state what happens if migration extends beyond October 12.
