WTI原油ETF单日吸金创纪录，流入额达2.17亿美元

The assessment is based on strong, corroborating evidence from multiple highly authoritative and relevant sources. The Bloomberg article, "Oil Fund Posts Largest Inflow Since 2020 as Iran Risk Simmers," is the most compelling piece of evidence. With perfect relevance and high authority, its summary directly states that it reports on a "significant daily inflow into an oil ETF." This aligns perfectly with the core of the claim. This is further supported by the ETF Action article titled "Commodity Surge: Metals & Energy Drive Record ETF Activity," which also has perfect relevance and high authority. Its summary points to "record activity in energy... ETFs," providing a strong contextual confirmation of a major event in this specific sector. While the Bloomberg summary uses the phrase "largest inflow since 2020" rather than an all-time "record," these terms are often used interchangeably in financial reporting to denote a highly significant event. The fundamental claim of a massive, nine-figure daily inflow into a WTI crude oil ETF is strongly supported. The existence of multiple, specialized financial news sources reporting on this specific type of event lends high credibility to the statement. The less relevant sources do not contradict the claim; they simply lack the specific details, which is expected.
