Bitcoin at $81,604 as $46.1B OI Builds Against Negative Basis

Bitcoin is trading at $81,604.4 with aggregate open interest at $46.1B, up 1.9% over 24 hours, while annualized futures basis is negative 9.5%. That combination is the central tension in the market: leverage is expanding as price rises, but derivatives traders are still paying for downside protection rather than chasing an enthusiastic long premium. The immediate structure favors a squeeze higher, yet the medium-term trend is not fully repaired because the futures curve remains defensive.

News flow is split between reports of rising institutional ETF ownership, an ambitious long-term price forecast, and warnings of a historic crash. That disagreement is visible in positioning: traders are not expressing a single clean directional view, and the derivatives data matters more than the competing narratives.

OI is rising across the main venues

The increase in exposure is broad rather than concentrated in a single exchange. Binance holds $8.9B of BTC open interest, or 19.4% of the tracked total, with its exposure up 1.8% over four hours and 1.8% over 24 hours. Bybit carries $4.6B, or 10.1%, after a 3.3% daily increase, while Gate has $5.4B, or 11.7%, after the strongest daily expansion among the major venues at 4.0%. OKX contributes $2.5B, or 5.4%, with a more restrained 0.8% daily rise.

This breadth matters because a price advance accompanied by rising OI usually means fresh risk is entering rather than merely old positions being closed. However, the direction of that risk is unclear. When OI increases alongside negative basis and negative average funding, the market is often building hedges, short futures or arbitrage positions rather than displaying outright bullish conviction. The result can be unstable: a modest upside extension can force shorts to cover, but a break of support can turn the same leverage into a liquidation cascade.

Funding and liquidations favor the squeeze case

Funding is positive on most major venues, including Binance, Bybit and OKX, but the aggregate funding average is negative. That divergence suggests the broad market is not uniformly paying to be long; isolated venues may have crowded long books while larger hedging flows keep the combined rate below zero. Account positioning reinforces the mixed picture. Across the tracked account sample, 49.6% are long, leaving a slight short majority. Binance shows 46.6% long against 53.4% short, and Gate is more aggressively short at 43.2% long versus 56.9% short. Bybit is modestly long at 51.9%, while Bitget is the most long-leaning account book at 55.4%.

Taker positioning is similarly split. Binance takers are 46.4% long and 53.6% short, while OKX takers are 58.1% long and 41.9% short. This is not a clean momentum signal, but it does identify the vulnerable side: shorts are more exposed on the venues where account and taker flow lean defensive, particularly when price remains above the recent forced-trade area.

Liquidations show that vulnerability already emerging. BTC liquidations reached $79.6M over 24 hours, including $55.8M of shorts against $23.8M of longs. Over 12 hours, short liquidations were $33.2M versus $10.8M for longs. The largest recorded event was valued at $7.1M around $80,380.1, while Binance also recorded short liquidations around $82,123.3 and $82,016.5. The asymmetry says the recent move has hurt shorts more than longs, and a return toward the upper liquidation prices could accelerate forced buying.

Negative basis keeps the medium-term signal cautious

The basis is the warning against treating the squeeze setup as a confirmed trend reversal. A negative 2.6% basis and negative 9.5% annualized basis indicate that futures are priced below spot, a condition more consistent with defensive hedging, short demand or a lack of confidence in sustained upside. At the same time, the four-hour RSI is 70.2 and the daily RSI is 65.1, showing that momentum is already elevated. Price can continue higher while shorts are trapped, but the market has less room for a disorderly long chase without first repairing the curve.

The critical area is therefore between the current $81,604.4 price and the $80,380.1 liquidation zone. Holding above that level while OI remains near or above $46.1B would keep the squeeze thesis active, with $82,016.5 and $82,123.3 serving as nearby evidence that short covering is still spreading. A move below $80,380.1 would be more dangerous than a simple pullback if OI stays elevated, because it would indicate that new leverage is not being absorbed and that long liquidation risk is replacing short-covering demand.

Verdict: BTC’s medium-term structure is squeeze-positive but not structurally bullish: shorts are the more fragile side above $80,380.1, while $46.1B of OI and the negative 9.5% annualized basis show that the market remains heavily hedged. The bullish view is invalidated if price breaks below $80,380.1 while OI holds above $46.1B and funding remains negative; that combination would favor leverage unwinding toward a bearish continuation rather than a healthy reset.
