The following communication was made available to CME Group Class B-1 shareholders on or after April 28, 2015


It was my honor to be nominated by the CME Class B-1 Nominating Committee as a candidate for Class B-1 Director on the CME Group Board of Directors.


Key Qualifications:


•    Extensive industry experience

•    Founder and leader of large proprietary trading firm

•    Focus on regulatory environment


I appreciate your support in this election.



Will Hobert, Founder WH Trading LLC

I believe that the paramount reason I was selected for this important role is based on my practical, hands-on knowledge and expertise of our industry. To put it concisely, I represent three decades of industry experience; first as an open outcry options market-maker, then together with our industry as a transformed electronic trader, and finally as a founder and owner of WH Trading—a highly successful proprietary shop. From its inception in 1994, I directed the technology, risk management, operations and strategy at WH Trading. The firm has developed exceptional in-house proprietary options and future trading software with performance at the microsecond level. Today, with over 60 employees, our firm trades in a wide range of futures and options both on the floor, the Globex platform, as well as on numerous exchanges worldwide.

I believe that the above credentials can be most valuable to the CME Group Board of Directors as our Exchange moves forward to face the very competitive globalized world of the future.

It goes without saying: The American financial services industry has experienced massive and unprecedented changes both to its capital markets as well as its trading counterpart. Over the past decade, in synch with this evolution, CME Group has grown and evolved into a technological powerhouse. Similarly, WH Trading has kept pace with these changes and also reinvented itself to adapt to the new trading landscape. As financial markets evolved and liquidity shifted from open outcry to the electronic screens, WH Trading, like CME Group, was required to make the difficult but necessary transition from a trading firm to a technology enterprise. I led this transformation at WH Trading and successfully guided the company through a major expansion into automated trading which intertwined with our floor operation. I believe that these proven skills are the values the Nominating Committee sought.

In addition, I have learned first-hand of the importance of the CME Group’s relationship with elected officials. I learned that our economic values as an industry have to be continuously guarded and explained. I have participated in informational sessions with the SEC and CFTC as well as with Congressmen and Senators and learned to advocate on our behalf, including traveling to Washington to discuss our positions. I have been included in direct meeting with John Boehner, the Speaker of the House, to help ensure that CME Group’s interests are presented and that CME Group’s legislative priorities are advanced. At Executive Chairman Terry Duffy’s request I have become a Director of the CME Group’s Political Action Committee. In this manner, I participate in choosing candidates who understand and support our agenda.


But we cannot rest on our laurels. The advancement of technology and the evolution of the financial markets is a never-ending process. In the coming years the ability to adapt to new changes, some of which are unpredictable, will dictate the CME Group’s growth and success. With options trading comprising approximately 20% of the CME Group’s volume, its members will be well served with a Board representative who is thoroughly steeped in the critical issues, complex market structure, and pressing problems facing option traders. In an environment where elements of open outcry, matching engines and voice brokers compete for options volume, I believe my 25 years of successful options trading, risk management, and strategic planning will provide a welcome addition to our Board of Directors.

If elected, I will apply all my experience and talent to work tirelessly to ensure that the CME Group and its members continue its leadership in the industry. I respectfully seek your support, stand ready to answer any question you may have.

Should you have any questions, or would like to chat, please do not hesitate to reach out to me. Please visit to learn more about me and see instructions about how to cast your vote electronically.
