The statement is assessed as "likely_true" with high confidence based on the overwhelming and consistent evidence presented across the provided sources. Multiple highly authoritative news outlets, including Reuters, Bloomberg, TechCrunch, and Business Insider, independently corroborate all key elements of the statement. They consistently report that Elon Musk has initiated legal action against both OpenAI and Microsoft, is seeking a specific monetary sum of up to $134 billion, and that the basis of the claim is fraud or 'wrongful gains'. The accusation of 'fraud' is explicitly mentioned by at least two high-authority sources. Furthermore, a primary source from one of the defendants, OpenAI, confirms the existence of the legal dispute by publicly refuting Musk's claims. The consistency of the specific financial figure ($134 billion) across numerous independent reports lends significant credibility to that part of the statement. The single irrelevant source was correctly identified and excluded from the analysis, and there are no contradictions among the remaining relevant sources.
