Eileen Gu, born in the United States to an American father and Chinese mother, holds birthright U.S. citizenship while competing for China after naturalizing there around 2019. Chinese law prohibits dual nationality, yet no public record exists of formal U.S. expatriation through the required process, and her name has not appeared on IRS expatriate publications. U.S. law does not automatically strip citizenship upon foreign naturalization without clear intent to renounce, and no government proceedings, indictments, or policy shifts have targeted her status amid ongoing geopolitical scrutiny. Traders assign a 98.5% probability to no revocation due to these structural legal barriers and the absence of triggering events. Realistic shifts could arise only from unprecedented actions such as congressional legislation altering birthright rules, confirmed evidence of material misrepresentation in her Chinese naturalization, or extraordinary national security findings—developments without precedent in comparable cases.
