On March 10, JELLYJELLY tokens experienced an extreme divergence between the perpetual contract mark price on mainstream trading platforms and the on-chain spot price: the perpetual contract mark price was $0.067, while the on-chain spot price was $0.092, with the maximum spread reaching approximately 34%. Analyst Ai Yi pointed out that open interest surged around 1 PM, with a trend highly similar to previous similar incidents, suggesting possible repeated price manipulation.

A significant deviation between the contract mark price and the spot price is one of the highest risk warning signals in the crypto derivatives market. Under normal market conditions, the perpetual contract mark price usually stays within a 1-2% reasonable deviation from the spot price; a deviation over 10% is abnormal, and a 34% divergence is almost impossible to explain through natural market behavior.
This divergence structure shows that the perpetual contract mark price ($0.067) is significantly lower than the on-chain spot price ($0.092), indicating that the contract side has been artificially suppressed, while the spot side has been relatively pushed higher. In this scenario, an extreme negative funding rate of -2% over 4 hours means short holders can collect 2% of their position every 4 hours from long holders—creating a strong short-term arbitrage incentive for shorts but imposing heavy holding costs on regular long positions.
Ai Yi warns of a manipulation pattern with a history in crypto markets:
Analysts warn investors that such extreme divergence between contract and spot prices often leads to forced liquidations and rapid price corrections, representing a high-risk window.
The abnormal divergence in JELLYJELLY also reflects structural risks in the ongoing integration of decentralized and centralized trading infrastructure. According to CoinGecko’s 2026 CEX and DEX trading report, DEX spot market share increased from 6.9% in January 2024 to 13.6% in January 2026, with DEX perpetual contract trading volume growing eightfold, and market share rising from 2.0% to 10.2%. Hyperliquid is the only DEX among the top ten perpetual platforms, holding a 3.3% share, surpassing some mid-sized CEXs.
In this context, when prices between on-chain spot and centralized exchange contracts diverge extremely, cross-platform arbitrage becomes more difficult due to factors like fund transfer speeds, gas fees, and liquidity depth differences. These barriers can extend the duration of the deviation, making manipulation more sustainable.
For those holding long contract positions, a -2%/4 hours funding rate means paying about 2% of their position every 4 hours to shorts, making long-term holding very costly. For spot holders, such a large price gap might present arbitrage opportunities by selling spot and entering long contracts, but they also face risks of market volatility and liquidity shortages.
-2%/4 hours translates to approximately -12% daily, which is extremely rare in crypto derivatives markets. Normal funding rates are usually between ±0.01% and ±0.1% per 8 hours; exceeding -0.5%/8 hours is abnormal. A rate of -2%/4 hours indicates a severely imbalanced and highly volatile market.
Analyst Ai Yi notes that current features include: abnormal concentration of open positions at surge points, extreme negative funding rates, and large discrepancies between spot and contract prices. These characteristics closely resemble previous JELLYJELLY incidents, where manipulators often build large short positions on contracts and then trigger forced liquidations in the spot market to profit.
