This week in crypto perpetual futures

Perpetual futures funding rates have climbed across the largest markets, signaling aggressive long positioning that is beginning to stretch relative to recent norms. Bitcoin, Ethereum, and Solana—which together account for the majority of open interest—are all displaying elevated annualized funding costs, with traders paying increasingly steep premiums to maintain leveraged long exposure. The combination of rising funding, growing open interest, and concentrated liquidation pressure among longs suggests the market is entering a phase of heightened positioning risk that warrants close monitoring.

Key takeaways

• BTC open interest jumped +12.2% in 24 hours to $15.9B, the largest single-day build in the dataset, while funding sits at 7.06% annualized—elevated but not extreme relative to its 71 percentile standing over 90 days.
• ETH funding has reached its most stretched level in recent history at 82 percentile, with an annualized rate of 7.77%, paired with aggressive week-long OI growth of +15.3% that signals sustained long accumulation.
• SOL shows the highest funding rate in the group at 9.34% APR and the most extreme 90-day positioning at 87 percentile, though its open interest base of $1.4B is substantially smaller than BTC or ETH.
• Liquidation imbalances favor long closures across BTC (+0.56), ETH (+0.48), and SOL (+0.19), indicating fragile leverage on the bid side and potential cascade risk if momentum reverses.

Bitcoin's outsized one-day surge

Bitcoin recorded a remarkable +12.2% jump in open interest over 24 hours, pushing total notional positioning to $15.9B. This single-day build is the sharpest move in the major cohort, though the weekly context is more measured: open interest has risen +1.7% over seven days, suggesting the bulk of the inflow arrived recently. Funding at 7.06% annualized remains elevated—traders are paying meaningful carry to hold leverage—but its 71 percentile ranking places it well above the median of its recent range without reaching historically stretched levels. The liquidation imbalance of +0.56 indicates more longs have been wiped out than shorts over the past day, a sign that some of the leverage building is already being tested. The leverage risk score of 20 ranks lowest among the major coins, reflecting BTC's deeper liquidity and more distributed positioning, which moderates cascade risk despite the absolute size of OI.

Bitcoin open interest surged 12.2% in one day while funding at 7.06% remains elevated but not extreme—a signal of rapid but not yet panicked long accumulation.

Ethereum's prolonged stretch

Ethereum presents a more concerning picture on the positioning front. Its funding rate of 7.77% annualized is the second-highest in the group and sits at the 82 percentile of its 90-day range—near the extreme end of recent behavior. More striking is the persistence of this build: ETH open interest climbed +15.3% over the past seven days while also growing +9.2% in the last 24 hours, evidence of continuous long accumulation rather than a single flush of inflow. The $10.9B in open interest represents the second-largest absolute position in the dataset. Liquidation imbalance of +0.48 shows material long-side pain, and the leverage risk score of 24 reflects ETH's elevated fragility relative to its peers. The combination of extreme 90-day percentile, high funding, and sustained multi-day buildup suggests trader conviction in upside that is not yet being shaken by adverse price action.

Solana, BNB and the alternatives

Solana exhibits the most stretched funding metrics of any major: 9.34% annualized funding at the 87 percentile, indicating near-record leverage by its own standards. However, the absolute open interest of $1.4B is far smaller than BTC or ETH, which limits systemic cascade risk even as the +0.19 liquidation imbalance hints at long-side pressure. The leverage risk score of 25 is elevated but still modest in absolute terms.

BNB and DOGE tell a different story. BNB has experienced explosive open interest growth of +161.7% over seven days, yet funding remains moderate at 8.61% annualized—positioned at 65 percentile, suggesting the market is not yet crowded relative to BNB's own history. Notably, its liquidation imbalance is -0.08, meaning more shorts have been liquidated than longs, a contrarian signal within the otherwise long-biased cohort. HYPE and DOGE, the smallest names by OI, show lower leverage risk scores (7 and 12 respectively), indicating their positioning remains more balanced and less fragile.

What would change this read

The current picture of elevated but manageable long-side positioning would shift materially if (1) funding rates normalize downward, signaling reduced demand for long carry and potential profit-taking; (2) open interest reverses—particularly if BTC or ETH post multi-day declines in OI comparable to the recent builds; or (3) liquidation imbalances swing sharply negative, meaning shorts begin accumulating losses at scale and longs show relative strength. A sustained rise in funding toward new 90-day highs combined with further OI growth would tighten the risk assessment; conversely, any sharp price break that triggers long liquidation cascades would rapidly clear positioning and reset funding toward zero or negative levels.
