The assessment is based on a strong inference from the available evidence, primarily the combination of Tesla's Q2 2025 update and the CNBC news report. 1. **Baseline Established:** The official Tesla Q2 2025 Update (Source 1) confirms that Tesla held Bitcoin at the beginning of the third quarter. This is a highly authoritative primary source that sets the context.2. **Analysis of Q3 Activity:** The most relevant source covering the Q3 period is the CNBC article (Source 2). Despite a likely typo in its publication date, its summary focuses on a "$600 million bitcoin profit jump after digital assets rule change." This language strongly suggests that the profit is an unrealized gain resulting from holding the asset, whose value appreciated and was reported differently due to a new accounting rule. If Tesla had sold Bitcoin, the report would likely have focused on a *realized* gain. If they had purchased more, that would have been the headline. The absence of any mention of a transaction in an article specifically about their Q3 Bitcoin holdings is compelling indirect evidence that no transaction occurred.3. **Absence of Contradictory Evidence:** No other provided source, whether authoritative or not, offers any information to contradict this conclusion. The official Tesla press release (Source 3) does not mention digital assets, and all other sources are irrelevant to the query.In summary, the available evidence strongly indicates that Tesla held its Bitcoin throughout Q3 2025. The reported profit jump is best explained by market price changes and new accounting rules rather than by a sale or purchase. While there is no direct primary source statement (like a Q3 financial report) explicitly confirming this, the inference from the high-quality secondary source is strong, leading to a high-confidence assessment that the statement is likely true.
