Milei achieves landmark victory in Argentina’s midterms, bolstering his congressional control.

Argentine President Javier Milei achieved a significant victory on Sunday, expanding his influence in Congress and providing his government with renewed momentum to advance substantial spending reductions and sweeping free-market reforms.

This outcome strengthens Milei’s libertarian movement and signifies another considerable shift for Argentina, one of Latin America’s largest and most dynamic economies.

Milei’s party, La Libertad Avanza, secured approximately 41.5% of the vote, representing a historic upset in a region traditionally dominated by the Peronist opposition. The rival coalition garnered 40.8%, according to figures from Reuters and The Associated Press.

Nationwide, La Libertad Avanza increased its seats in Congress from 37 to 64, positioning Milei to more easily defend his vetoes and executive decrees that are central to his economic agenda.

“The result surpassed even the most optimistic hopes of Milei’s supporters,” Marcelo Garcia, Americas director at the risk-analysis firm Horizon Engage, remarked in comments reported by Reuters. “With this result, Milei will be able to readily defend his decrees and vetoes in Congress.”

Political consultant Gustavo Cordoba informed Reuters that the outcome reflected a cautious optimism among voters who seem prepared to grant Milei’s administration more time.

“Many people were willing to give the government another chance,” Cordoba stated. “The triumph is undeniable, unquestionable.”

Reuters reported that inflation dropped to 2.1% last month. His government has also posted a fiscal surplus and implemented extensive deregulation measures — a dramatic reversal after years of economic turbulence.

According to The Associated Press, the U.S. government, under President , offered Argentina a $40 billion aid package, which included a $20 billion currency swap and a proposed $20 billion debt-investment facility, after linking future U.S. support to Milei’s performance in the midterms.

President Donald Trump congratulated Milei on Truth Social Sunday night, writing: “Congratulations to President Javier Milei on his Landslide Victory in Argentina. He is doing a wonderful job! Our confidence in him was justified by the People of Argentina.”

Investors reacted favorably to the results. Reuters indicated that Argentine bonds and stocks are expected to rally as Milei’s stronger standing in Congress provides him with the political capital to .

Milei referred to the election as “a turning point for Argentina,” according to AFP via the Times of Israel.
