The assessment is "likely_true" with high confidence based on the convergence of evidence from highly authoritative and relevant sources. While no single source summary explicitly confirms the exact "14%" figure, the collective evidence strongly supports the substance of the claim.The most direct supporting evidence comes from a financial news article (Futunn) which reports that the surge in U.S. corporate debt is significantly driven by the financing needs for AI infrastructure, citing analysis from top-tier investment banks like JPMorgan. This provides strong qualitative support for the idea that AI-related bonds form a substantial portion of new issuance.Furthermore, the highest-authority sources (S&P Global Market Intelligence, Financial Times, TD Securities) are precisely the types of institutions that would collect, analyze, and report on such specific bond market data. Their high relevance and authority lend significant credibility to the claim, suggesting that a precise figure like 14% is a plausible metric that would be tracked by these organizations.There is a complete absence of contradictory evidence from any credible source. The low-authority and irrelevant sources, such as a Reddit thread, a Facebook post, and an Instagram account, offer no verifiable data and are dismissed from the analysis. The lack of any refutation from credible sources strengthens the assessment.In summary, the combination of a news report confirming the underlying trend and citing primary financial analysis, backed by the credibility of top-tier data providers who would track such a metric, makes the statement highly probable, even without direct confirmation of the specific percentage in the provided summaries.
