Institutions now drive 72% of spot OTC volume, up from 59% a year earlier. "At three quarters of volume, institutional flow defines market structure," Wintermute noted in an in-house report. This shift towards institutional participation underscores the growing importance of broker-dealers like Wintermute in shaping the market.

Wintermute aims to rival Citadel Securities, a designated market maker for over 1,900 stocks, including 62% of NYSE listings. To achieve its goals, Wintermute will need to navigate the complex regulatory landscape, including the $75 million capital requirement for a designated market maker. Citadel Securities has also been chosen as the designated market maker for 80% of NYSE IPOs.

The registration of Wintermute as a broker-dealer may lead to increased competition in the ETF market, which could have significant implications for market participants.

$43.2 billion in annual trading volume is driven by institutions, highlighting the significance of Wintermute's broker-dealer registration. 72% of spot OTC volume is driven by institutions, up from 59% a year earlier, demonstrating the growing importance of institutional participation. 3-5 years is the timeframe Wintermute has set to rival Citadel Securities, an ambitious goal that will require significant expansion and investment.

Analysis: If Wintermute can successfully execute its 5-year plan, it may pose a significant challenge to Citadel Securities' dominance in the ETF market. A break below the current market share of Citadel Securities would signal a significant shift in the ETF market, potentially leading to increased competition and better pricing for investors. Wintermute's ability to navigate the regulatory landscape and attract institutional clients will be crucial to its success. The next 12-18 months will be crucial in determining Wintermute's ability to execute its plans and challenge the status quo in the ETF market.
