About Us

The PEAK6 Difference

Located in the historic Chicago Board of Trade Building, PEAK6 is redefining what it means to be an investment firm. We’re driven to see solutions others don’t — and capitalize on opportunities others miss. We operate with a focused, entrepreneurial drive and push ourselves to think differently. This ambitious, visionary approach has helped us become the diverse range of successful businesses we are today, spanning proprietary trading, retail brokerage, and sophisticated clearing services. 

Different businesses. A wealth of opportunities.

Founded on a great idea

PEAK6 Investments, L.P. was created from the same ambitious, entrepreneurial culture that thrives in the firm today. Co-founders Matt Hulsizer and Jenny Just started their careers at O’Connor and Associates — a Chicago-based options trading firm with a particular specialty, and emphasis, on financial derivatives. In 1992, the firm was acquired by Swiss Bank Corporation. After the acquisition, Swiss Bank decided to head in a new direction.

Entrepreneurs at heart, Matt and Jenny wanted to bring a different vision to life and decided to launch their own firm. And in 1997, PEAK6 Investments was launched. PEAK6 Investments became one of the first firms to develop electronic, proprietary technology, which more efficiently manages risk in the options market. This disciplined focus on risk management and technology has helped us achieve significant success in managing risk, providing liquidity, and making markets. From this singular focus, the firm continued to innovate, growing PEAK6 into a diverse group of thriving, successful businesses that now span many areas of the financial services sector.


In 2006, PEAK6 launched two new businesses, looking to reach an entirely different set of investors. PEAK6 launched OptionsHouse — an online, consumer retail brokerage. OptionsHouse delivers an exceptional combination of value and technology for active options traders. PEAK6 also launched PEAK6 Advisors, LLC — an SEC-registered investment adviser. PEAK6 Advisors now has over $1 billion in assets under management.



Then, in 2012, PEAK6 expanded its operational expertise into the clearing business with an investment into Apex Clearing Corporation. Apex remains an independent, privately held clearing firm and PEAK6 provides the management team, the day-to-day operational oversight, and the risk management necessary to run the Apex business.



After building OptionsHouse into a top-ranked online brokerage, PEAK6 announced in May 2014  that they entered into a definitive agreement to sell OptionsHouse to General Atlantic, a well-established global growth investor.

Today, PEAK6 remains anything but your typical investment firm. Every day, our culture motivates us to seek out, and invest in, good ideas that have the potential of becoming great businesses. We’re always looking for ways to deliver untapped, exceptional value to the market.

Our values

But, our culture isn’t for everyone. We don’t have a laundry list of fluffy values that sound good but no one really gets. It’s a short, focused list and embodies our essence. We live and breathe these values across the entire firm. In a nutshell, we hire, fire, and promote through this lens.

Why the name “PEAK6”?

Not surprisingly, the story behind the PEAK6 name began in the mountains. Matt was in Breckenridge, Colorado and inspiration struck. He recalled someone once telling him it takes 6 peaks to make a mountain range. He was drawn to this notion of peaks and how they can stand alone and/or work together to form something even more powerful. This perfectly represented the vision for the new firm. And with that, the PEAK6 name took hold. Interestingly, the peak that Matt used as inspiration for our name so many years ago actually opened to the public for the first time this ski season at Breckenridge (2013-2014). They named it Peak6. And no — we had nothing to do with it. It’s just fate working its magic.

PEAK6 Capital Management

PEAK6 Capital Management LLC is a proprietary trading (e.g., prop trading) business and was the first business to be launched in PEAK6.   As a prop trading firm, our goal is to generate returns on our own capital (we don’t trade external capital).

Our Capital Management business specializes in equity derivatives trading and became one of the first firms to develop electronic proprietary technology, which more efficiently manages risk in the options market.

Our disciplined focus on risk management, and technology, has helped us achieve significant success in managing risk, providing liquidity, and making markets. We have a proven track record of success, providing significant liquidity throughout U.S. financial markets.

PEAK6 Capital Management is currently located in Chicago, with offices in the Board of Trade.


Launched in 2006, OptionsHouse was created with the vision of delivering a compelling combination of value and technology direct to the active, online trader.

OptionsHouse leveraged the insights from the technology-driven approach that originally made PEAK6 successful, and translated that into a successful, direct-to-consumer business.

The result is a top-rated, online brokerage that has won multiple Barron’s awards. OptionsHouse offers professional-level tools, innovative technology and fast execution—all at incredibly competitive prices. We’re committed to providing active traders with the rates and tools they need to gain a competitive edge in the market.

OptionsHouse currently has offices in Chicago and Seattle.
