SAO PAULO, Dec 8 (Reuters) - Brazilian brokerage XP Inc wants to "dominate" the South American country's investment market, chief executive Thiago Maffra said on Friday, adding the firm's goal is to double its market share in the long-term.

Maffra said at an investor event in New York that XP believes it can reach a market share of 14-15% by 2026, up from 11% at the end of the third quarter. (Reporting by Gabriel Araujo; Editing by Kylie Madry)
