金先物が史上初の1オンス4,850ドル突破

The assessment is primarily driven by a single, highly authoritative and relevant source. This source, a near real-time data provider for gold prices, directly corroborates the core elements of the claim by reporting that gold set a new record high at a price of over $4,720 per ounce. This figure is extremely close to the $4,750 mentioned in the statement and confirms that a new historical peak was reached. While the exact figure of $4,750 is not explicitly confirmed, the reported price of "over $4,720" makes it highly plausible that the price did or briefly touched $4,750. Other potentially authoritative sources on precious metals prices were provided, but their summaries lacked specific, timely data to either confirm or deny the claim. One source was entirely irrelevant as it pertained to copper prices. In the absence of any conflicting evidence and with strong, direct support from the most credible source, the statement is assessed as very likely to be true.
