Miami International Holdings (MIAX) Stock Forecast: What Could Drive It in 2026
Short answer
What is actually driving Miami International Holdings (MIAX) right now is Options market-share gains: MIAX has climbed to a record 18.2% share of US options volume in Q4 2025 from roughly 14.5% a year earlier, moving it to fourth place among US operators. Gross revenue (TTM) is ~$1.4B. If that keeps playing out, the setup is favourable; the risk to it is mIAX competes against Cboe, Nasdaq, and NYSE, all far larger with deeper balance sheets, broader product suites, and pricing power that could compress MIAX's take rates. No one can predict where MIAX trades, and Walnut does not publish targets, so treat this as a scenario, not a price target or prediction.
What could drive Miami International Holdings (MIAX) higher?
1. Options market-share gains
MIAX has climbed to a record 18.2% share of US options volume in Q4 2025 from roughly 14.5% a year earlier, moving it to fourth place among US operators. Record average daily contract volumes and higher revenue per contract are compounding on top of that share growth. Continued share gains against Cboe, Nasdaq, and NYSE are the single biggest driver of the story.
2. High-margin, recurring revenue model
Exchange economics are attractive: transaction fees and market-data subscriptions recur, and incremental volume flows through at very high margins. MIAX's adjusted EBITDA margin expanded toward 50% in Q4 2025 from the mid-30s a year earlier. Operating leverage on a fixed technology base is a core part of the thesis.
3. Diversification across asset classes and geographies
Beyond US options, MIAX operates equities (MIAX Pearl Equities), futures (MIAX Futures), and international listing venues (Bermuda Stock Exchange, The International Stock Exchange). This gives it multiple growth avenues and reduces reliance on any single product, though options remains the dominant profit engine today.
4. Capital-markets tailwinds
Structurally rising retail and institutional options activity and elevated market volumes have lifted the whole listed-derivatives industry. As long as options trading volumes keep growing, a rising tide supports MIAX's revenue even before its own share gains are counted.
What could weigh on MIAX?
MIAX competes against Cboe, Nasdaq, and NYSE, all far larger with deeper balance sheets, broader product suites, and pricing power that could compress MIAX's take rates. Its revenue is sensitive to trading volumes, which are cyclical and can fall sharply in quiet or risk-off markets. As a newly public company with a short trading history, the stock carries a growth valuation (a price-to-earnings ratio in the high 20s) that leaves little margin for a volume or share stumble. Reported GAAP earnings have been lumpy around the IPO and portfolio moves such as the sale of most of MIAXdx to a Robinhood and Susquehanna joint venture. Exchanges are also heavily regulated, so rule changes on fees, market structure, or payment-for-order-flow could affect the business.
