According to @StockMarketNerd, Amazon AMZN is adding Nubank NU’s NuPay checkout to its Brazilian store, indicating NuPay will appear as a payment option on Amazon Brazil (source: @StockMarketNerd). The post does not include an official press release or terms, so traders should treat this as an unconfirmed report and monitor NU and AMZN price and volume for reaction (source: @StockMarketNerd). No crypto assets such as BTC or ETH are mentioned in the post, suggesting limited immediate direct impact on crypto markets from this item alone (source: @StockMarketNerd). Key trading checks include whether Amazon Brazil’s checkout flow shows NuPay live and whether Nubank or Amazon issue confirmations during Brazil market hours (source: @StockMarketNerd).
