Sui OI Purge: $778M Open Interest, 6.1% Bybit Slide and Long Risk

Sui derivatives are showing a clear positioning reset: aggregate open interest stands at $778.1M after falling 0.5% over 24 hours, while the token trades at $1.0156. The purge is not broad panic, but it is concentrated enough to matter: Bybit OI dropped 6.1%, OKX fell 3.3%, and the largest venue by share, Gate, declined 0.8%. Market coverage has recently focused on Sui moving faster than Bitcoin during a broader crypto rally, but the derivatives tape now points to crowded long exposure being trimmed.

Where the OI is being removed

Gate holds the largest disclosed SUI futures share at 21.4%, equal to $166.8M, followed by Binance at 18.5% and $144.1M. Bybit contributes 11.8%, or $91.7M, while Bitget accounts for 8.5% and $66.4M. That concentration makes the Bybit move especially relevant: its OI fell 3.7% over the latest 4-hour window, compared with 1.1% at Gate, 1.3% at Binance and 1.0% at Bitget. OKX is smaller at 5.2% share, but its 4-hour decline of 1.1% and 24-hour decline of 3.3% reinforce the same direction.

The overall 4-hour declines across these leading venues suggest liquidation and position reduction rather than fresh leverage chasing the spot move. Binance is the exception on the daily horizon, adding 0.5% over 24 hours, yet it still lost 1.3% in the latest 4-hour comparison. That combination indicates that some capital is rotating between venues, while the broader derivatives base is still shrinking.

Funding stays positive, but flow disagrees

The funding rate map remains mostly positive. Binance, OKX, Bybit and Gate each show 0.0% after one-decimal rounding, while Bitget is also 0.0% at a slightly lower 0.0051% raw reading. The standout is CoinEx at 0.2%, compared with negative readings at Crypto.com and EdgeX. Positive funding across the main books means longs are still paying to hold exposure, even as OI contracts.

That is a warning sign for the quality of the rebound. Account positioning shows 71.6% of SUI accounts long overall. Bybit is the most one-sided among the listed venues at 75.4% long, Bitget reaches 78.4%, and Binance sits at 70.4%. Yet active taker flow is much less bullish: Binance is nearly balanced at 50.5% long and 49.5% short, while Gate takers are 40.0% long and 60.0% short. The gap between passive account bias and active execution suggests traders are holding long inventory, but aggressive orders are leaning toward selling or hedging.

Liquidations confirm a long-side flush

The liquidation structure is decisively asymmetric. Over 24 hours, SUI liquidations totaled $2.6M, including $2.1M in longs and $569.9K in shorts. In the latest 12-hour window, longs lost $786.1K against $53.4K for shorts. The 4-hour split is even sharper: $415.2K of long liquidations versus only $1.6K of shorts, while the latest hour recorded $56.1K in long liquidations against $1.2K in shorts.

This is consistent with the account-versus-taker divergence. Longs are not merely overrepresented; they are the side paying the immediate cost as leverage is removed. The absence of a comparable short squeeze also reduces the evidence for a fresh upside impulse from forced buying.

Verdict

The exclusive read is bearish-to-neutral: SUI can stabilize above $1.0156 only if the OI purge slows while total OI holds near $778.1M and taker selling stops widening. A loss of $1.0156 together with OI expanding above $778.1M would invalidate this view by signaling that new leverage is entering on the downside rather than being flushed. Until that signal appears, the combination of concentrated OI declines, positive funding and $2.1M in long liquidations favors a continued cleanup of crowded longs over a durable breakout.
