Aptos OI Purge Watch: $121.2M Open Interest, 12.5% Higher
Aptos is trading at $0.7761 after a 6.0% move, but the more important signal is leverage: total open interest stands at $121.2M, up 12.5% over 24 hours while the latest hour slipped 0.1%. That combination points to a crowded derivatives market that has started to shed exposure at the margin rather than a clean, broad-based reset.
Market commentary is also watching Aptos test the upper end of its recent range, making the interaction between price, positioning and forced closures more important than the spot advance alone.
Bybit and Binance carry the leverage
The exchange split shows where the risk is concentrated. Bybit holds the largest reported share at 24.5%, with $29.6M in OI and a 12.8% 24-hour increase. Binance follows at 23.6% and $28.5M, but its growth is faster at 15.9%. Together, those venues represent the core of the visible leverage build.
OKX is smaller at 5.1% and $6.2M, yet its 4-hour change is down 2.4%, the sharpest short-term contraction among the leading venues. Bitget contributes 7.3% and $8.8M, with OI up 3.6% over 24 hours and 1.4% over 4 hours. The pattern is therefore uneven: the largest books have expanded across the day, while OKX and the broader market are beginning to release risk in shorter windows.
Funding is positive, but not uniform
The average 8-hour funding reading is 0.0135%, keeping the directional cost positive for longs. Binance shows 0.010%, while Bitget is lower at 0.007% and Gate at 0.003%. Bybit is an outlier on the other side at -0.004%, and OKX is more negative at -0.023%. This dispersion matters because it weakens the case for a single, synchronized long premium across venues.
There is also an extreme outlier at CoinEx, where the current rate is 0.263%. That rate is far above the readings at the largest books and should be treated as an isolated venue signal rather than proof that the entire APT market is paying an equivalent premium. The basis is 0.0% when rounded to one decimal, while its annualized reading is 14.1%, reinforcing that carry remains a factor even as exchange-level funding diverges.
Liquidations and positioning disagree
The liquidation tape confirms that the recent move has punished shorts more heavily over the broader window. In 24 hours, short liquidations reached $249.1K versus $161.7K for longs, for a total of $410.8K. The 12-hour window shows the same structure: $186.6K in shorts against $66.5K in longs. Over 4 hours, shorts accounted for $152.1K while longs accounted for $39.1K.
Yet the account data remains aggressively long. Across the reported snapshot, 68.5% of accounts are long. Bybit is the most stretched account book at 74.4% long, followed by Binance at 70.2% and OKX at 65.6%. Active flow tells a different story: Binance takers are 30.1% long and 70.0% short, while Gate takers are 44.6% long and 55.4% short. This account-versus-taker split suggests passive or existing accounts are still leaning bullish, while traders initiating positions are selling into strength.
Verdict: The current setup is a late-stage leverage test, not a confirmed bearish reversal. The key level is $0.7761 with OI at $121.2M: holding price while OI continues to cool would support an orderly purge, but a fresh move above $0.7761 accompanied by OI rising from $121.2M would invalidate that view and signal renewed leverage expansion.
