Now, we’re bringing what we’ve built to the public markets,” said Marco Margiotta, CEO of House of Doge. “What started as a community-led ambition has matured into an infrastructure engine for Dogecoin. By going public through this merger, we’re opening access and unleashing the next wave of innovation, institutional participation, and mainstream utility for Dogecoin.”

By embedding Dogecoin into the fabric of Gen Z’s experiences, across college campuses, sports, gaming, and communities, we are not merely creating new business lines; we are unlocking a multi-billion-dollar avenue to mainstream digital currency acceptance and shareholder value creation. Brag House is now well-positioned as the public company vehicle for the next generation of global finance, a widely accepted, culturally integrated, and institutionally supported currency.”
