According to @StockMKTNewz, OpenAI has reportedly held preliminary talks about raising up to USD 100 billion at an around USD 750 billion valuation, stated in an X post dated Dec 18, 2025 (source: @StockMKTNewz). Based on those figures, a USD 100 billion primary raise at a USD 750 billion post-money valuation would imply approximately 13.3 percent new ownership, while if USD 750 billion is pre-money the implied post-money would be about USD 850 billion with roughly 11.8 percent new ownership (source: calculations using figures reported by @StockMKTNewz). The post does not include an official filing or company confirmation, so traders should treat this as a single-source headline and wait for corroboration before sizing positions or adjusting risk (source: @StockMKTNewz).
