The assessment of "likely_true" is based on a strong piece of direct evidence that specifically corroborates the claim, which outweighs weaker or contextually different contradictory information.The most compelling evidence is a crypto news article that directly and explicitly states that the circulating supply of USDC decreased by approximately $500 million. This source has the highest possible relevance (1.00) as it mirrors the user's query precisely.The attribution of this action to Circle is factually correct and supported by multiple sources, as Circle is the sole issuer of USDC and manages its circulating supply through the processes of minting and redeeming tokens. There is conflicting evidence, but it is less convincing. A live earnings blog from a major financial news source states that USDC circulation rose. However, this source is given a very low relevance score (0.10), and its summary notes that it mentions "$500 million" and "USDC" in separate, unrelated contexts, which significantly weakens the credibility of its contradiction. Additionally, an official quarterly earnings release from Circle states that the supply grew over the entire quarter. While this seems contradictory, quarterly growth does not rule out a significant decrease within a specific one-week period of that quarter. Therefore, the direct, highly specific evidence supporting the statement is considered more impactful than the contradictory evidence, which is either of low relevance or describes a different timeframe.
