Pump.fun Open Interest Climbs 12.7% as Shorts Face $5.4M Liquidations

Pump.fun derivatives open interest climbed 12.7% in 24 hours to $654.1 million across the venue breakdown, while the ticker snapshot placed aggregate OI at $662.0 million. Price stood at $0.006681, up 8.4%, and the market recorded $1.1 billion in turnover. The combination points to a leverage-led rally rather than a move driven only by spot demand. Recent coverage has centered on renewed whale interest, a sharp PUMP advance and the project’s changing position within the Solana launchpad market.

Binance leads the new exposure

Binance held the largest identified share at $151.1 million, or 23.1% of tracked OI, after rising 20.3% over 24 hours and 8.5% over the latest 4-hour window. OKX was smaller at $48.3 million and 7.4% of the total, but its 29.4% daily increase and 11.6% 4-hour increase show that leverage expanded faster there. Bitget contributed $26.8 million, or 4.1%, with OI up 14.3% daily and 7.1% over 4 hours. Gate was only $9.1 million, or 1.4%, yet still added 13.7% in a day.

This distribution matters because the rise is broad enough to avoid being explained by one venue alone, while the fastest percentage gains are appearing on smaller bases. The immediate risk is therefore not simply excessive Binance concentration. It is the possibility that traders across several venues added positions into an already extended price move.

Funding is mostly calm, but not uniform

The ticker’s average 8-hour funding rate was 0.1%, a positive reading that confirms longs are paying shorts overall. On the largest venues, however, current rates were much more restrained: Binance, Bitget and Aster each showed 0.005%, while OKX was 0.00125% and Backpack was 0.00125%. Gate was slightly negative at -0.0016%, suggesting that the leverage build has not produced a uniformly crowded long trade.

The outliers deserve more attention than the headline average. Bitunix showed 0.610308%, and CoinEx showed 0.387227%, while Coinbase was negative at -0.0663%. These readings may reflect venue-specific positioning and should not be treated as the market-wide clearing price for leverage. Still, the gap between the positive ticker average and near-flat major-venue rates says the OI surge is real, but its carry burden is uneven.

Short liquidations confirm squeeze pressure

The liquidation structure is the clearest bullish signal. Over 24 hours, total liquidations reached $6.5 million, with $5.4 million from shorts and $1.1 million from longs. The same imbalance appeared in every reported window: during the latest hour, shorts lost $1.3 million versus $0.1 million for longs; over 4 hours, the split was $2.4 million against $0.1 million; over 12 hours, shorts accounted for $3.3 million versus $0.3 million for longs.

Yet positioning data adds an important contradiction. Across the ticker snapshot, 47.8% of accounts were long, compared with only 42.3% of active takers. On Binance, accounts were 54.4% long, but takers were 39.9% long; on Gate, accounts were 45.9% long while takers were 33.0% long. OKX was the exception, with 39.8% of accounts long and 51.3% of takers long. In other words, passive account positioning is not uniformly bullish, while aggressive traders were often selling into the move. That helps explain why shorts were liquidated even as fresh short-side execution remained visible.

Verdict: PUMP’s near-term bias remains squeeze-positive while price holds $0.006681 and tracked venue OI stays above $654.1 million. The view is invalidated if price loses $0.006681 at the same time that OI falls below $654.1 million, which would turn the current expansion into a deleveraging signal rather than continuation.
