The statement is directly confirmed by Source 10, a report from 'Americans for Tax Fairness,' which states that 'American billionaires reached a record breaking $7.6 trillion of personal wealth as of Labor Day 2025.' While this primary source is an advocacy group, the claim is contextually supported by multiple other credible sources (such as Oxfam and UBS) that report a significant surge in billionaire and overall wealth during the 2024-2025 period, adding strong corroborative weight to the specific figure.
