Open interest is building fastest in these markets

Open interest is accelerating dramatically across a cluster of smaller-cap crypto derivatives, signaling a rapid influx of fresh leverage into markets that had been lightly positioned. The surge is led by MUFG, which posted a staggering +2908.2% jump in open interest over the past 24 hours, though the absolute notional base remains modest at $226,193. Alongside it, six other tokens have recorded four-digit and high-triple-digit increases in positioning, yet their funding rates and liquidation patterns paint a mixed picture of which direction new capital is flowing and how stable these positions truly are.

Key takeaways

• MUFG recorded the largest 24h OI increase at +2908.2%, followed by SUMIELEC (+489.4%) and SIMO (+476.5%), indicating fresh leverage entry into micro-cap markets.
• ERA and LA stand out for extremely negative funding rates (-1913.21% and -3310.18% annualized, respectively) despite rising open interest, a rare divergence suggesting shorts are being aggressively funded or squeezed.
• Most rapidly building markets show zero or near-neutral liquidation imbalance, except SIMO (all longs liquidated on the day) and LA (moderately net long liquidations), indicating either balanced positioning or inadequate data on directional conviction.
• ERA and LA both sit at the extreme bottom of their 90-day funding percentile at 0, meaning their current funding is at its most shorts-favorable level in months—a potential turning point signal.

MUFG leads an explosive wave

MUFG's +2908.2% 24-hour surge in open interest is the most aggressive single-day build in the dataset. However, the context matters: at $226,193 total notional, the market is still tiny and prone to sharp percentage swings from modest inflows. The aggregated funding rate sits at 0.00%, neutral, which typically signals balanced sentiment between longs and shorts. With a leverage risk score of 64, MUFG's positioning is elevated but not yet in the extreme zone. The absence of 7-day OI change data leaves unclear whether this surge is a one-day spike or part of a sustained trend.

The four-in-a-row rebound: SUMIELEC, SIMO, EUV, AMC

Three other tokens—SUMIELEC, SIMO, and EUV—recorded 24-hour OI increases in the +437% to +489% range, while AMC followed at +434.4%. SUMIELEC, with $34,839 in open interest and 7-day OI growth of +1042.1%, shows sustained momentum rather than a one-day event. Its funding rate of 0.00% and a moderate leverage risk score of 32 suggest measured growth. SIMO presents a more cautious profile: $826,475 in open interest and a 7-day rise of +1058.9% are substantial, yet its liquidation imbalance of +1.00 (meaning all 24-hour liquidations were longs) hints at weak hands exiting even as fresh leverage enters. EUV, by contrast, saw a sharp 24-hour jump of +437.6% but only +14.0% over the week, suggesting the recent surge is concentrated in the last day. AMC's +1460.0% 7-day growth dwarfs its 24-hour +434.4%, indicating the real acceleration happened earlier in the week.

ERA's funding rate of −1913.21% annualized, combined with +443.1% OI growth, reveals shorts are being paid substantially to stay short—a supply-demand extreme.

ERA and LA: extreme funding inversions

The most striking figures belong to ERA and LA, both showing catastrophically negative funding rates alongside rising open interest. ERA's -1913.21% annualized funding rate sits at the 0th percentile of its 90-day range, meaning shorts are collecting payments at a frequency and magnitude not seen in the past three months. Yet ERA's open interest climbed +443.1% in 24 hours and +508.4% over a week, totaling $13.9M. This divergence—new leverage entering while shorts are supremely overpaid—suggests either a capitulation squeeze in progress or data lag in pricing. LA is even more extreme: -3310.18% annualized funding, also at the 0 percentile, paired with +282.6% OI growth and $12.6M notional. LA's liquidation imbalance of +0.50 (net long liquidations) reinforces the picture of long weakness. Both tokens carry elevated leverage risk scores (ERA at 88, LA at 67), indicating structural fragility.

What would change this read

This snapshot would invert if funding rates across these markets began normalizing toward positive territory—particularly for ERA and LA, whose -1913.21% and -3310.18% readings cannot persist indefinitely. If 24-hour OI growth slowed or reversed from the current wave, the "fresh leverage" narrative would evaporate. Liquidation imbalance would become decisive if a persistent directional bias emerged (sustained net long or short liquidations) rather than the current near-zero patterns. A material spike in the leverage risk scores, or a drift of these micro-cap markets toward the higher percentiles of their funding ranges, would signal danger consolidating rather than dispersing. Finally, if 7-day OI changes flattened or turned negative while 24-hour changes remained positive, it would suggest positioning is churning rather than accumulating.
