What Bybit is changing on Aug. 1, 2026
TLDR KEYPOINTS
- Bybit is changing max open interest limits for selected perpetual contracts.
- The change is limited to specific contracts, not all products.
- The update takes effect Aug. 1, 2026.
Bybit has scheduled a change to the maximum open interest limits on a set of selected perpetual contracts, according to the exchange’s maintenance update notice. The change applies only to the contracts named in the notice rather than across the full derivatives lineup. For related coverage, see Bybit Lists REUSDT Perpetual Contract With Up to 20x Leverage.
Max open interest limits cap the total size of outstanding positions a trader can hold in a given perpetual contract. On Bybit, these thresholds are defined per contract, as detailed in the exchange’s open interest limit help documentation. For related coverage, see Bybit Lists BILLUSDT Perpetual Futures Contract.
Why the update matters for perpetual contract traders
A contract-specific change to open interest limits can affect position planning, since the ceiling on outstanding exposure is one of the parameters that governs how large a position a trader can build. Traders holding or planning positions in the affected contracts should review the new figures before Aug. 1, 2026. For related coverage, see Bybit Lists METAUSDT Perpetual Contract With Up to 10x Leverage.
The adjustment sits alongside other risk-parameter work Bybit has carried out, including a broader risk limit adjustment on perpetual contracts earlier in 2026. Open interest limits are distinct from funding rates and leverage tiers, and this notice addresses the open interest ceiling specifically.
The exchange continues to expand its perpetual lineup with listings such as the REUSDT perpetual contract and the METAUSDT perpetual contract, each carrying its own contract-level parameters.
What users should watch before the Bybit deadline
With a firm effective date set, timing is relevant for current position holders. Traders should confirm whether any of their open contracts appear in the list of selected perpetuals covered by the change.
Bybit publishes contract parameter changes through its maintenance and product updates channel, where the exact per-contract figures are posted. Reviewing existing open positions against those figures ahead of Aug. 1, 2026 is the practical step for anyone trading the affected markets.
