The assessment is based on multiple high-authority and high-relevance primary sources from Binance's official website. A key piece of evidence is a direct announcement from Binance for a very similar event—a pre-trading program for a different perpetual contract (BTW)—scheduled for December 22, 2025, just one day before the date in the statement. This establishes a clear and verified pattern of Binance launching such products during this exact timeframe, making the claim about LITUSDT highly plausible.Furthermore, the provided sources include the main Binance announcement hub and specific support pages dedicated to new listings and futures contracts. These are identified as the most authoritative and relevant locations to find and verify this type of information. The summaries indicate these pages contain notices for new trading pairs and futures contracts in December 2025. The combination of a directly analogous announcement and the identification of the official, authoritative locations for such news provides strong, compelling evidence supporting the statement.There is no contradictory information in any of the provided sources. The lower-authority sources are irrelevant as they discuss different exchanges or different products (spot trading vs. perpetual contracts), but they do not challenge the claim.
