Peter Thiel’s recent presence in Argentina alongside reports of a luxury property purchase and high-level meetings with President Javier Milei has fueled fresh speculation about whether America’s ultra-wealthy are beginning to leave the United States.
The billionaire PayPal co-founder has spent time in Buenos Aires and also held meetings with top officials while staying in the upscale Barrio Parque neighborhood. But while Thiel’s moves have sparked debate over a “billionaire exodus,” the data suggest this is not happening on a large scale—at least not yet.
Why It Matters
Fears that wealthy Americans are fleeing the U.S. have implications for tax revenue and economic competitiveness. The top earners account for a disproportionate share of federal tax revenue, and even small shifts in where they live or how they structure their residency can influence local economies.
What To Know
The most concrete data point tracking Americans leaving the country is citizenship renunciation, which is recorded by the Treasury Department. That IRS data shows a clear long-term increase:
- Pre-2009: 200 to 400 per year
- 2015: 4,279
- 2020 peak: 6,705
- 2024: roughly 4,800 to 5,000
While that represents a significant rise compared to decades past, the absolute numbers remain small relative to the U.S. population.
“In an increasingly interconnected global economy, people with means have more options regarding where they live and work,” Kevin Thompson, the CEO of 9i Capital Group and the host of the 9innings podcast, told Newsweek. “The broader impact on the U.S. economy is likely minimal.”
Most People Giving Up Citizenship Are Not Billionaires
Based on the data available, it also does not appear that billionaires are driving the trend of expatriation.
Many people renouncing their citizenship are either dual citizens or long-term expatriates. Even though IRS expatriation lists include many wealthy individuals (generally with net worths above $2 million), they do not include only billionaires.
“The billionaire exodus story is partly overstated if we define it as wealthy Americans abandoning the U.S. en masse,” Michael Ryan, a finance expert and the founder of MichaelRyanMoney.com, told Newsweek. “The better point of view is that the ultra wealthy are no longer thinking in terms of one home country. They are building jurisdictional portfolios…homes, passports, tax residencies, business hubs, and political hedges.”
Some billionaires relocate part-time or maintain multiple residences, but wealth is often kept invested in U.S. markets even if families move abroad. Around 36 percent of surveyed billionaires say they have relocated at least once, with others considering it, according to a UBS billionaire survey.
That aligns more closely with Thiel expanding his presence abroad instead of fully severing ties with the United States.
Wealthy Americans Are Moving Inside the U.S.
More broadly, wealthy Americans are moving, but often within the United States rather than outside it.
One National Bureau of Economic Research study found that the number of Forbes 400 billionaires in states with estate taxes fell by 35 percent after tax rules changed. That has led to migration patterns, with wealthy Americans moving from New York to Florida, for instance, or from California to Texas.
“Among billionaires, a small number of moves can matter symbolically and economically,” Ryan said. “These individuals control businesses, foundations, investment capital, political donations, and local tax bases. When they relocate, the financial impact may be narrow, but the signal is broad.”
What About Argentina?
Thiel’s activity in Argentina appears tied to both political alignment and investment exploration. The billionaire has met multiple times with the nation’s president and spent extended time in Buenos Aires, including discussions with senior government officials and attending private meetings.
The move could reflect a broader trend of the ultra-wealthy seeking to establish footholds in multiple jurisdictions amid broader political or economic uncertainty.
“There is a larger trend of ongoing geopolitical concerns and increased taxation in some states making it easier for some wealthy Americans and mobile professionals to look abroad,” Alex Beene, a financial literacy instructor for the University of Tennessee at Martin, told Newsweek.
“However, some of these international moves among America’s highest earners have been going on for years, and ultimately the moves meant little for the businesses tied to them.”
What Happens Next
There are signs that interest in leaving or diversifying away from the U.S. has increased in recent years, driven by a mix of political polarization and tax considerations. Post-pandemic lifestyle shifts have also encouraged the trend, but it’s typically confined to the wealthiest Americans who have the ability and capital to move elsewhere quickly.
“Many Americans would likely make the same decision if they had the financial resources and flexibility to do so,” Thompson said. “For most people, the limiting factor is not desire, but access and affordability.”
