Bitcoin-focused Latin American company OranjeBTC is set to go public on Brazil’s B3 exchange in early October with more than $400 million in BTC reserves, making it Brazil’s largest publicly-traded bitcoin treasury firm.

The move, confirmed by local news outlet Brazil Journal and at Mercado Bitcoin’s DAC 2025 conference, will see it go public via a reverse merger with Intergraus, a prep-course provider already listed on the exchange. Once the transaction closes, Oranje will assume Intergraus’ public listing with a roughly 85% free float.

Oranje holds 3,650 bitcoin, roughly six times more than Brazilian fintech Méliuz, the only other major publicly-traded bitcoin treasury firm in the country. The sum would rank Oranje among the top 25 corporate bitcoin holders globally, and the company aims to expand that reserve aggressively, according to local media.

Backing the venture are high-profile crypto investors including Cameron and Tyler Winklevoss, bitcoin pioneer Adam Back, trading platform FalconX, and Mexican billionaire Ricardo Salinas Pliego. Institutional players like Off the Chain Capital and ParaFi Capital also participated in the initial round, the report added.

Alongside its treasury play, Oranje plans to launch a financial education platform focused on bitcoin and crypto, using Intergraus’ existing infrastructure.
