Funding extremes: the most stretched perpetuals

Extreme Funding Across Micro-Cap Perpetuals

As of June 19, 2026, a cohort of low-liquidity perpetual futures markets displays funding rates of historically extreme magnitude. The observed funding spreads reveal a market divided between intense short-squeezing conditions on one side and severe long crowding on the other. These dynamics are concentrated in coins with modest open interest, where positioning imbalances can drive annualized funding into four-digit percentage territory. Understanding the distribution of these extremes illuminates the fragility embedded in leverage-heavy micro-cap derivatives.

The most pronounced negatively-funded asset is RE, carrying an aggregated funding apr of -3264.96%. This deep negative funding indicates sustained short dominance—shorts are collecting substantial payments from long holders, a signal that shorts control positioning and longs are either trapped or betting against prevailing sentiment. RE's funding percentile of 6 confirms this rate sits near the floor of its 90-day range, meaning current short dominance is unusually pronounced relative to its own recent history. With open interest of only $13.6M, the market is shallow enough that even modest position shifts can produce extreme rate swings. PORTAL follows with -1115.28% annualized funding, and SAHARA at -741.93%, both reflecting a consistent theme: certain micro-cap markets are decisively short-biased, and longs are paying a steep rent to maintain exposure.

On the opposite flank sits SIREN, where aggregated funding apr reaches 1049.45%—a positive rate indicating longs dominate and are paying shorts. SIREN's funding percentile of 97 is striking: this positive funding sits in the 97th percentile of its 90-day distribution, meaning current long crowding is near an extreme for that asset. The open interest is $6.8M, and the leverage risk score stands at 85, signaling elevated structural fragility. BTW presents a similarly stretched scenario with 573.83% positive funding at the 98th percentile, paired with the highest leverage risk score of 97 and $33.0M in open interest—the largest notional position in this cohort. BTW's extreme percentile ranking and high leverage score suggest a market where long positioning is compressed and vulnerable to deleveraging or liquidation cascades.

Positioning Imbalance and Liquidation Signals

The liquidation imbalance figures reveal asymmetric stress. TRUST shows a liquidation imbalance of +1.00, meaning 100% of 24-hour liquidations favored longs, indicating long holders were preferentially forced to exit. Conversely, H records -1.00, implying all liquidations favored shorts, suggesting short positions faced the brunt of forced closure. These binary outcomes, combined with micro-scale open interest in most names, underscore how thin these markets are: a single large liquidation can swing the imbalance metric sharply.

RE and SAHARA, both short-heavy with negative funding, show liquidation imbalances of -0.17 and +0.00 respectively, suggesting their short dominance has not yet translated into cascading short liquidations. This may indicate shorts are either well-capitalized or that the short positions were established at lower leverage. By contrast, SIREN's zero imbalance and BTW's zero imbalance, despite their extreme long funding, hint that long liquidations have been sparse—perhaps because long holders are paying to stay in, or because their positions have not yet tested critical liquidation thresholds.

Funding Percentiles and Historical Context

Funding percentiles offer a lens on whether current extremes are cyclical or unusual. SIREN's 97th percentile and BTW's 98th percentile together indicate that positive funding across long-heavy names is near historically stretched levels for those particular assets. RE and SAHARA, by contrast, sit at percentiles 6 and 7 respectively, meaning their deep negative funding is not novel—they appear to be persistently short-biased markets where this dynamic recurs. H at the 10th percentile similarly suggests its -540.49% negative funding, while extreme in absolute terms, is within the normal range of that market's behavior. The contrast suggests some markets (RE, SAHARA, H) structurally attract short interest, while others (SIREN, BTW) are currently experiencing acute long crowding relative to their own recent norms.

Scale and Liquidity Considerations

Open interest varies widely: BTW commands $33.0M, H carries $22.9M, and RE holds $13.6M. The remainder—SIREN ($6.8M), SAHARA ($4.7M), PORTAL ($2.3M), TRUST ($1.2M), and BTT ($426,046)—operate at substantially smaller scales. This disparity matters because funding rate extremes in $2M markets carry different implications than those in $33M markets. BTW's high leverage risk score of 97 paired with $33.0M open interest and 573.83% positive funding suggests meaningful leverage concentration among longs in a market sized to amplify price moves. Conversely, PORTAL's -1115.28% funding, while numerically more extreme than BTW's positive rate, applies to only $2.3M of notional open interest, limiting systemic spillover risk.

Synthesis and Forward Signals

The data reveals a bifurcated landscape. Short-heavy markets (RE, PORTAL, SAHARA, H, BTT, TRUST) display uniformly negative funding, with longs under pressure. Long-heavy markets (SIREN, BTW) show positive funding at or near 90-day extremes, coupled with elevated leverage risk scores. Neither regime is stable indefinitely: negative funding persists because shorts remain confident, but eventual reversal could trigger sharp squeezes; positive funding in long-crowded markets attracts new long leverage until capacity breaks. The absence of open interest change data limits visibility into whether these positions are being built or unwound, but the extreme funding levels themselves suggest markets are pricing substantial execution stress and positioning imbalance into the annualized cost of carry.
