Miami International Holdings reported October options average daily volume of 11.290 million contracts, down 13.5% from a year earlier. The decline was substantially steeper than the 0.8% fall in industry options volume, reducing MIAX’s market share to 16.9% from 19.4%.[1]
The annual comparison contrasts with a 5.4% increase from September and a 16.6% rise in year-to-date options average daily volume. October had 22 trading days, against 23 a year earlier and 21 in September; daily averages make these periods more comparable than raw monthly contract totals.[1]
October trading by business
| Business | Average daily volume | Year-on-year change |
|---|---|---|
| MIAX options exchanges | 11.290m contracts | −13.5% |
| US options industry | 66.628m contracts | −0.8% |
| MIAX Pearl Equities | 106m shares | −51.4% |
| MIAX Futures agriculture | 9,333 contracts | +28.1% |

MIAX’s options share fell by 2.5 percentage points. On the equities side, MIAX Pearl’s daily share volume fell 51.4%, against a 17.6% decline for the industry; its reported market share fell to 0.6% from 1.0%.[1]
Futures offered a different picture. Agricultural daily volume rose 28.1% year on year, although its year-to-date average remained 17.0% lower. Financial futures daily volume increased 117.1% from September to 4,833 contracts, an expansion from a small base following the May launch.[1]
The figures show why the group’s trading businesses need separate comparisons. Year-to-date options growth and recent financial-futures expansion coexist with an October loss of options share and weaker equity activity.[1]
