Will any part of the United States federal government take a stake of above 0% in Pfizer?

If any part of the United States federal government has taken a stake of Pfizer before Jan 1, 2027, then the market resolves to Yes. Taking a stake means acquiring direct equity ownership, voting shares, or equivalent ownership interests. This includes indirect ownership through wholly controlled investment vehicles and convertible rights treated as equity. Pre-existing stakes count toward the threshold. Ownership is aggregated across all share classes and listings. Crossing the threshold at any point satisfies the criterion regardless of subsequent changes. Non-equity instruments like bonds or loans don't qualify. Stakes by sovereign wealth funds or state-owned enterprises attributed to the body count. The value can be expressed as percentage ownership, monetary value, or share count, with percentage being the default unless specified.
