Miami International Holdings debuted strongly, trading at a significant revenue discount to peers but with lagging margins, making valuation a balancing act. MIAX's operating leverage is improving, with margins reaching 25% in H1 2025, but still trails industry leaders like CBOE and ICE in profitability. At over 6x sales and 25x operating profits post-IPO, MIAX is not cheap on earnings but offers upside if it can close the margin gap.
