Open interest is building fastest in these markets

Explosive Leverage Building Across Smaller Altcoins

Open interest is surging across a cluster of smaller-cap altcoins as of June 20, 2026, signaling aggressive fresh leverage entry into markets that have historically traded with thin liquidity and tight regulation. The largest 24-hour open interest increases cluster around ALICE, BTW, and RARE, which have seen positioning expand by +188.8%, +146.4%, and +85.2% respectively. The speed of this buildup—particularly the week-long gains of +210.5% for ALICE and +1019.1% for BTW—suggests coordinated leverage accumulation rather than gradual organic growth. What distinguishes this cohort is not size but velocity: total open interest across these assets remains modest (ALICE at $5.8M, BTW at $141.5M, RARE at $3.4M), yet the rate of position expansion indicates market participants are allocating fresh capital into vehicles that typically lack the infrastructure and visibility of major exchanges.

The concentration of activity in lower-liquidity assets creates an asymmetric risk environment. When open interest doubles or triples in thin markets, the bid-ask spread widens, execution slippage increases, and the capacity to unwind large positions without market impact shrinks. This dynamic is amplified when funding rates signal directional crowding, as they do across this cohort. Understanding the direction of this new leverage—whether fresh longs or shorts are entering—requires reading the funding rate signal in conjunction with the open interest velocity.

Extreme Short-Side Crowding in ALICE and BICO

ALICE and BICO present the most extreme funding dislocations. ALICE's aggregated funding rate of -905.13%, annualized, represents a historic short squeeze environment where shorts are paying longs massively to maintain their positions. Combined with a funding percentile of 1 over the past 90 days, this indicates ALICE funding is at its lowest extreme relative to its own recent distribution. The positive read is straightforward: shorts are compressed and forced to subsidize longs at rates that are currently far below the asset's 90-day norm. Yet ALICE's open interest of $5.8M and leverage risk score of 99 warn that absolute positioning remains fragile and heavily leveraged despite the short-favorable funding.

BICO tells a similar but slightly different story. Its aggregated funding rate of -212.11% with a funding percentile of 0 places it at the absolute floor of its recent range, again favoring short position holders who face cost. However, BICO's liquidation imbalance of +0.43 over the past 24 hours signals that longs have been liquidated more aggressively than shorts during the recent move. This mismatch—deeply negative funding yet long liquidations—can arise when price moves sharply, triggering cascading long closures even as the cumulative cost structure favors shorts. BICO's open interest of $25.2M, while the largest in the short-favoring cohort, rose +75.5% in 24 hours and +992.7% over seven days, suggesting the asset has cycled through multiple leverage waves.

Long Accumulation Under Positive Funding in BTW and SLX

In contrast, BTW and SLX display the opposite extreme: positive funding rates that penalize longs. BTW's aggregated funding rate of 586.68%, with a funding percentile of 97, situates it among the highest funding costs observed in the 90-day window. This is textbook crowded long positioning: longs are paying shorts generously to hold their positions, and the current funding rate is unusually elevated relative to recent history. Yet BTW has attracted +146.4% new open interest in 24 hours and +1019.1% over seven days. The implication is that leverage entry is occurring despite the high cost of holding longs—either traders are contrarian to the funding signal, or momentum and conviction overwhelm rational funding-rate arbitrage.

SLX reinforces this pattern, though with lower absolute positioning. Its aggregated funding rate of 83.93% with a funding percentile of 99 indicates that while longs are being charged to hold positions, the cost is at the extreme high end of its recent range. SLX's open interest of $9.7M has grown +59.6% in 24 hours. Unlike the heavily liquidated long positions in BICO, SLX shows a liquidation imbalance of -0.24, meaning shorts have faced slightly more pressure than longs. This suggests that despite high long funding costs, new longs entering SLX are not immediately being flushed out—instead, shorts are taking losses.

Mixed Signals in Mid-Range Open Interest

Assets like AXS, SAND, and BEL occupy the middle ground between crowded shorts and crowded longs, yet all are posting strong 24-hour open interest gains. AXS at $24.9M shows a -23.01% funding rate with a funding percentile of 31, indicating moderately cheap positioning relative to its range. Its +78.4% 24-hour open interest increase and -0.32 liquidation imbalance suggest that shorts are accumulating and taking small losses. SAND, with $12.5M open interest, carries a -9.37% funding rate at the 25th percentile, also neutral-to-short-favorable, yet has seen +58.8% open interest growth. BEL, the smallest at $6.9M, sports a -77.87% rate at the 1st percentile, placing shorts in the driver's seat even as leverage surges.

These middle-tier assets share a common thread: negative funding despite aggressive open interest growth, which means shorts are gradually subsidizing incoming leverage without immediate forced liquidations. This setup can persist until a sharp directional move triggers cascade unwinds.
