Mercado Pago Brazil Overtakes Caixa in Cards as Revenue Hits US$2.2 Billion
Mercado Pago Brazil, a unit of MercadoLibre, says it became Brazil’s sixth-largest card issuer, overtaking Caixa, citing its own card-issuer ranking and CardMonitor data. It reported US$2.2 billion net revenue in Q2, up 63%. Cards drove growth (2.6M new cards), but card net interest margin fell to -2.5%.
How this was made

The 30-second read
Why it matters
The key trade-off for traders is revenue momentum versus card profitability, plus regulatory and deposit-protection differences versus licensed banks.
Market read
A concrete Q2 revenue and card-growth datapoint, plus a stated lack of a Brazil banking license, frames near-term growth versus margin risk for MELI-linked investors.
What to watch
Card NIM is after credit losses, so changes in loss rates, funding costs, and mix (on-us vs off-marketplace spend) could reverse the margin trend faster than revenue growth alone implies.
Background
Mercado Pago Brazil claims it has overtaken Caixa to become Brazil’s sixth-largest card issuer, while operating without a full banking license.
Ticker impact
Mercado Pago Brazil’s US$2.2B net revenue in Q2 is sourced from MercadoLibre’s quarterly results, linking the update to MELI’s reported performance.
Near-term sentiment likely mixed, with traders weighing faster revenue growth against worsening card economics.
