MIAX Volume Surge Signals Options Market Share Gains
Event summary
- MIAX Exchange Group's average daily volume (ADV) increased 25.1% year-over-year to 11.1 million contracts in January 2026.
- The group's market share rose to 17.6%, a 5.5% increase year-over-year.

The big picture
MIAX's strong January performance underscores its success in capturing market share within the options and futures trading landscape. The 25% YoY volume increase significantly outpaces the 18.6% growth of the U.S. equity options industry, suggesting MIAX is effectively attracting liquidity. However, the contrasting performance of MIAX Pearl highlights potential vulnerabilities within its equity offerings and the need for continued strategic differentiation.
What we're watching
- Competition
- The sustainability of MIAX's market share gains will depend on its ability to continue attracting order flow away from competitors like NYSE, particularly given the broader industry growth.
- Pearl Performance
- The decline in MIAX Pearl’s ADV warrants investigation; it could signal challenges in attracting equity order flow or increased competition within that segment.
- Regulatory Scrutiny
- Increased trading volume and market share may draw greater scrutiny from the SEC regarding market structure and potential conflicts of interest.
