The assessment of the statement as 'likely_true' is based on the unanimous and consistent evidence provided by all five sources. The highest authority source, a Bloomberg report, explicitly states that Alphabet's bond is the 'first 100-year bond' from a tech company since the dot-com era. This claim is directly corroborated by other reputable sources such as Business Insider and several other financial news outlets, all of which repeat the same fact. There are no contradictions in the provided evidence. The consistency across multiple independent reports, including those with high authority in financial news, lends significant credibility to the statement. While there is a minute possibility that a smaller, less-publicized tech company may have issued such a bond, the consensus among major financial media makes this highly unlikely. Therefore, the evidence strongly supports the truthfulness of the statement.
