Open interest is building fastest in these markets

Leverage is flooding into a small cluster of micro-cap derivatives markets, with T posting a staggering +4824.9% surge in open interest over the past 24 hours. That explosive build—from a base of $6.0M notional—arrives alongside deeply inverted funding, where shorts are being paid heavily by longs. The pattern signals fresh positioning entering these thin-liquidity venues, but the velocity and funding backdrop expose meaningful fragility risks.

Key takeaways

• T and SXT dominate the 24-hour OI surge list, with +4824.9% and +1076.1% gains respectively, indicating rapid leverage accumulation in sub-$7M markets.
• Deep negative funding across the top movers—T at -709.12% APR and SXT at -765.08% APR—suggests shorts are defending against aggressive long entry, a classic crowded-short setup.
• PARTI stands apart with positive funding at 28.50% APR and funding percentile of 100, marking it as the most stretched long-biased market in the dataset.
• Leverage risk scores for T (86) and SXT (88) indicate elevated fragility; both sit near the extreme end of the risk spectrum.

T and SXT: The twin spike story

T's +4824.9% 24-hour OI increase is the dataset's most explosive move. At just $6.0M total open interest, even a modest liquidation cascade could drain liquidity fast. The co-movement with SXT—which posted +1076.1% growth to reach $2.9M—suggests these are not isolated spot rallies but coordinated leverage entries, likely driven by a single catalyst or trader positioning.

Both markets are anchored by sharply negative funding rates. T's -709.12% annualized rate and SXT's -765.08% reveal that shorts are being paid to hold, a structure that typically forms when longs crowd in aggressively. This is not a signal of crowded longs paying away—it is the inverse: shorts are profitable and defensive, but the funding magnitude hints that new long leverage is arriving faster than shorts can absorb it.

A funding rate of -709.12% APR in a $6.0M market signals shorts are extracting value to offset incoming long pressure, a fragile equilibrium.

Neither asset has moved far up its 90-day funding percentile curve. T sits at 6 and SXT at 5, meaning these deeply negative rates are *historically normal* for them, not at all-time extremes relative to recent history. That context matters: the market is not yet warning of a structural breaking point, but the micro-cap venue and explosive OI growth demand caution.

PARTI: A different regime—long saturation

PARTI presents a contrasting picture. Its open interest of $14.2M dwarfs the others on this list, and its funding rate of 28.50% APR is robustly positive—longs are paying shorts. Crucially, PARTI's funding percentile stands at 100, the highest in the dataset. This signals that its current positive funding is at the top extreme of its own 90-day range, a hallmark of crowded long positioning.

The liquidation imbalance of -0.33 reinforces this read: more shorts have been liquidated than longs over the past day, consistent with a market biased toward long excess. Where T and SXT show shorts defending against new long inflow, PARTI shows longs already dominant and funding stretched to reward shorts for taking on the accumulated long bias. The leverage risk score of 63 sits moderate, not alarming, but the funding percentile at 100 is the true warning flag.

ANKR, OG, CVC, and V: Graduated buildup with lower risk

The remaining four symbols show OI gains in a more measured band: ANKR at +101.2%, OG at +60.0%, CVC at +53.9%, and V at +53.4%. These are real increases but far below the viral spike seen in T and SXT. Funding rates are mixed. ANKR carries negative funding at -553.05% APR (funding percentile 3), suggesting mild short defense. OG and CVC, by contrast, show modest positive funding rates (9.55% and 8.29% respectively), with percentiles at 45 and 51—neutral zones, neither crowded nor unusual.

Leverage risk scores reflect the distinction. OG (24), CVC (22), and V (23) all sit in the low-to-moderate band, well below the elevated tier occupied by T and SXT. ANKR's score of 73 is elevated but not extreme. These markets are building leverage, but in sizes and funding structures that do not yet signal acute fragility.

What would change this read

Watch for funding normalization in T and SXT. If -709.12% and -765.08% rates begin to converge toward zero or flip positive, shorts have absorbed the long inflow and equilibrium is setting. Conversely, if those rates accelerate further negative, it signals ongoing short capitulation and higher liquidation risk.

Monitor open interest reversal. The +4824.9% and +1076.1% surges cannot sustain indefinitely in micro-cap venues; if 7-day OI data (currently unavailable) shows deceleration or contraction, the acute build phase is ending. Lastly, watch liquidation imbalance. Currently T and SXT show +0.00, but if longs begin liquidating en masse, the fragility of these thin markets will become evident in seconds.
