The assessment is "likely_true" with high confidence based on strong, corroborating evidence from multiple authoritative sources. The statement claims a $150 million liquidation of short positions occurred within one hour. Direct support for an event of this scale and timeframe comes from a crypto data platform, which reported that approximately $150 million in futures contracts were liquidated within a single hour. While this source doesn't specify if the positions were short or long, it confirms the core financial figure and the time period.Crucially, another high-authority source, a major crypto data aggregator, reported on a "short squeeze" event that triggered $206.48 million in liquidations of short positions. A short squeeze, by definition, involves the liquidation of short positions. This report, while citing a different dollar amount, provides definitive proof that mass liquidations of short positions on a scale even larger than $150 million have occurred.There is some conflicting evidence. Two sources mention a $150 million liquidation event within an hour, but their context of a market price drop implies these were long positions, not the short positions specified in the statement. However, the existence of a major liquidation of long positions does not preclude the existence of a separate, major liquidation of short positions. Given the direct confirmation of the event's scale and timeframe, combined with definitive proof that mass liquidations of short positions do occur at this magnitude, the original statement is highly plausible and well-supported. The evidence confirms that events of this specific nature and scale are a documented feature of the cryptocurrency markets.
