This is just the "Davidson Window," which is based on a CIA report that Xi directed the PLA to be ready to take Taiwan by 2027. ADM Davidson took that and used it as a warning to the US military that China is ramping up their capabilities, and other officers, lawmakers, and intelligence folks ran with that until they started saying "China will invade Taiwan in 2027." Evidently, CEOs were briefed for some (probably stupid or corrupt) reason.
Personally, I think too many senior American leaders read into that report and Davidson's warning. Plus, most people who really know anything about China don't think that China will move kinetically against Taiwan around 2027.
