The assessment is based on strong, direct evidence from the most authoritative source provided. The primary source is a post from Tether's CEO, Paolo Ardoino, who stated that the company currently has over $6.8 billion in excess reserves and projects profits exceeding $10 billion for the first three quarters of 2025. Since Tether's profits are added to its surplus reserves, this projection directly supports the claim. The total projected surplus by the end of Q3 2025 would be the current $6.8 billion plus the projected $10+ billion in profit, resulting in a total well over $16 billion. This figure clearly qualifies as 'billions in surplus reserves'.This primary evidence is further corroborated by two secondary news sources from Bitget, which report the same figures, citing Tether's projections of '$10B+ 2025 profits with $6.8B excess reserves'. The remaining sources were found to be completely irrelevant to the query, discussing other companies or general financial concepts, and offered no contradictory information. The evidence is consistent, comes from a high-authority primary source, and directly substantiates the statement.
