WHO WE ARE Headquartered in the historic Chicago Board of Trade, PEAK6 Capital Management is a proprietary options trading firm that has been defining the industry for more than 25 years.

We thrive due to our firm’s special blend of financial acumen, ability to manage risk, and cutting‑edge technology. Our success is driven by our team of technologists, engineers, and traders who leverage proprietary tech and a data‑centric approach to maintain inventory and stay ahead of the markets, so customers can, too.
