LATAM Airlines Group SA (LTM) saw its stock soar 5.72% in pre-market trading on Monday, as part of a broader rally among U.S.-listed Chilean companies. The surge comes amid growing optimism surrounding Chile's political landscape, with far-right presidential candidate Jose Antonio Kast now favored to win the runoff election next month.

The airline's strong performance is not isolated, as several other Chilean firms trading on U.S. exchanges also posted significant gains. Compania Cervecerias Unidas rose 5.6%, SQM shares increased by 5.3%, and Banco Santander Chile climbed 5.4% in pre-market trading. This widespread rally suggests a macro factor affecting Chilean equities as a whole, likely tied to the potential political shift in the South American nation.

Investors appear to be viewing Kast's potential victory as favorable for business interests and economic policies in Chile. As LATAM Airlines is a major player in the country's economy, its stock is benefiting from this broader market optimism. The positive sentiment extends beyond the airline and beverage sectors, with financial institutions and other industries also experiencing notable gains, indicating a comprehensive boost for Chilean stocks listed in the U.S.
