Miami International Holdings Inc., (NYSE: MIAX), made an impressive entrance into the public markets Thursday. Its shares surged by 37.6% on their first trading day.
This is the first major US financial exchange to be floated in over 15 years. It also comes at a time when investor interest has increased in exchange operators.
The shares opened at $31.65, which is significantly higher than the initial public offering price of $23, and was itself priced $2 over the upper end of the market range from $19 to $20.
The sale of 15,000,000 shares raised $345 million. Underwriters had a 30-day right to buy up to 2,25 million more shares.
This offering will close on the 15th of August.
MIAX, founded in 2007, is headquartered in Princeton (New Jersey) and operates an extensive portfolio of asset exchanges.
Thomas Gallagher, Chief Executive of the Group, stressed that technology, infrastructure and relationships with participants in the market are key to differentiating themselves from their competitors.
Option trading is at its core
MIAX is a nine-exchange network that includes options, equities cash, futures and international markets. However, its main source of revenue comes from the trading of options.
In 2012, the company introduced its first option exchange and over the last decade has increased its share of market.
According to Options Clearing Corporation, MIAX held 16% of US option market in the first half 2025. It was only behind the New York Stock Exchange (NYSE), Nasdaq and Cboe.
MIAX is now in a position to take advantage of the recent surge in volumes, fueled by market volatility.
Matt Kennedy, senior analyst at IPO-research firm Renaissance Capital noted, “It is a niche, but one that investors feel comfortable in.” MIAX has clearly been riding a multi-year trend in the option space.”
Expansion of product offering
MIAX is ready to expand its product portfolio. Gallagher, which does not currently offer any crypto-futures products, has shown openness towards partnerships to bring these offerings to their futures exchange.
MIAX also secured an exclusive licensing deal with Bloomberg Index Services for ten years.
Launches are planned for 2025 to 2026. The first products under the deal will be index futures and options on Bloomberg US Large Cap Price Return Index B500.
The exchange portfolio of the company includes four US option markets, an equities cash exchange, US futures, and a controlling interest in Bermuda Stock Exchange.
MIAX owns Dorman Trading – a commission-based futures merchant – and LedgerX – rebranded MIAX Derivatives Exchange – which offers US Futures and Options on Futures that are fully collateralised.
Strong financial performance
MIAX announced $1.14 billion total revenue in 2024. This was accompanied by $102 millions in net profit and $0.69 per share diluted.
The company has consistently seen its contract volume grow. In the US, the average volume per day on the options market rose from 1,000,000 contracts in 2015, to 6.7,000,000 in 2024 and 8.6,000,000 in the first quarter 2025.
MIAX, with its expanding footprint, diversified offering and robust debut on the market, is in an excellent position to capitalize both on established opportunities and those that are emerging in global financial markets.
The post Miami International Holdings launches strongly on NYSE at $2.51 billion valuation is subject to change as new information becomes available.
