Much of the growth was driven by the company's BYX Exchange, which set a monthly market share record of 3.7% less than two years since its October 2010 inception.

"Our strong momentum continued in August with the best U.S. equities monthly market share performance in our six-year history," said President and Chief Executive Joe Ratterman. "We also witnessed further success in our options business and new record market share in Copenhagen, Frankfurt and Vienna.

"Increasingly, the broker-dealer community appreciates the price improvement, reliability, and overall trading experience on the platforms we operate, contributing to our consistent growth," he said.

BATS Chi-X Europe also remained the largest pan-European market by notional value traded in August, with monthly market share exceeding 25% in the UK, German, Swiss, Dutch, Swedish and Finnish markets. Overall European market share was 23.8%. Monthly records were achieved in Germany's MDAX (29.0%), Denmark's OMXC20 (22.3%) and Austria's ATX (18.7%).

In the U.S., BATS Options again recorded month-over-month matched market share of 3.7% up from 3.6% in July.

BATS operates two stock exchanges in the U.S., the BATS BZX Exchange and BATS BYX Exchange (the BATS Exchanges); BATS Options, a U.S. equity options market; and BATS Chi-X Europe, which runs an FSA-authorized multilateral trading facility.
