MIAX Q1 2026 Earnings Transcript

Miami International Holdings posted record Q1 net revenue of $129 million, up 40% year over year, with adjusted EBITDA rising 66% to $66 million and margin expanding 800 bps to 51%. Options revenue grew 37% to $111 million on 10.9 million average daily contracts, while market share improved to 17.3%; the company also reaffirmed full-year opex guidance of $265 million to $275 million and expects a May 17 launch of Bloomberg equity index futures. Cash ended at $551 million with debt below $2 million, and the MIAXDX sale contributed a $51 million gain plus a $70 million tax benefit.

Analysis

MIAX is becoming a higher-quality cash compounder, but the market may still underappreciate how much of the current margin step-up is coming from mix shift rather than just volume. The key second-order effect is that growth in higher-capture floor activity and complex order flow can expand RPC faster than headline market share suggests, which is why earnings power can keep surprising even if share oscillates quarter to quarter. That dynamic also makes the name less exposed to a single volume print and more dependent on product design, routing preferences, and microstructure changes.

The Bloomberg futures launch is the more interesting catalyst than the reported quarter. If even a modest slice of equity beta migrates into MIAX’s new suite, the company can layer incremental fee streams on top of an already leveraged cost base, while the OCC-clearing angle may attract participants looking for margin efficiency rather than pure trading alpha. The risk is execution: futures adoption tends to be slower than equity options, so the near-term story likely hinges on marketing spend and liquidity-provider onboarding before revenue meaningfully inflects.

The MIAXDX divestiture is easy to misread as a one-time gain and ignore, but the retained 10% stake creates a free embedded call on prediction-market adoption without capital drag. That said, the larger strategic takeaway is capital allocation: with a near-debt-free balance sheet and ample cash, MIAX can fund product launches and bolt-on deals while competitors are forced to be more selective. The main downside is that valuation can compress if investors conclude the current EPS uplift is overly benefited by non-recurring items, front-loaded CapEx, or temporary market volatility rather than durable operating leverage.

Key Decisions for Investors

• Long MIAX on a 3-6 month horizon; thesis is that the market is underpricing the combination of mix-driven RPC expansion and operating leverage. Use pullbacks after post-earnings digestion to build exposure; downside is that a quieter volatility regime could slow volume growth, but the business still has multiple self-help levers.
• Pair trade: long MIAX / short a lower-quality exchange or market-structure peer with weaker mix and less balance-sheet flexibility. The spread should work if investors continue rewarding higher-capture flow and product innovation rather than just headline volume growth.
• Buy MIAX May/June call spreads to express the Bloomberg futures catalyst ahead of launch and early onboarding feedback. Risk/reward is attractive because the market only needs to believe in a credible revenue ramp, not full maturity, but time decay is a risk if initial liquidity is thin.
• Avoid chasing HOOD as a pure read-through from the prediction-market JV; the economics are de minimis near term. If anything, MIAX is the cleaner way to play optionality around new market structure without underwriting retail trading volatility.
• For hedged accounts, consider a tactical short on volatility-sensitive exchange/market-data names if consensus extrapolates a normalization in options volumes. MIAX’s higher-capture mix makes it relatively resilient versus peers that rely more on pure transaction growth.
