The assessment is based on a strong consensus across multiple, independent, and credible sources. Several primary sources with high to medium-high authority directly and explicitly state that the market capitalization of USD1 has surpassed that of PYUSD. A report from TheStreet, a reputable financial news website, confirms this, citing a market cap of approximately $4 billion for USD1. This claim is corroborated by reports from crypto-focused outlets Coinpaper and Phemex. The Phemex article provides the most specific evidence, reporting a market cap of $4.54 billion for USD1 versus $3.69 billion for PYUSD as of a specific date. Other sources, while having lower authority or relevance, support the context of USD1's rapid growth compared to PYUSD. There is no conflicting evidence presented among the sources; those that do not directly support the statement are irrelevant to the specific market cap comparison. The high degree of consistency and direct confirmation from multiple journalistic sources makes the statement highly likely to be true.
