The transaction will leverage the technology and expertise of both firms to enhance corporate bond trading on a global scale, delivering innovative tools that help identify likely counterparties and improve quality of execution with greater information protection.

The acquisition of CodeStreet enables Tradeweb to pair effective trade execution and processing with better trade identification tools for the buy-side and enhanced workflow management for liquidity providers, which will enable buy-side investors to better source liquidity.

"We are committed to building the most comprehensive electronic corporate bond marketplace, and the acquisition of CodeStreet is a valuable building block in expanding our established offering with improved sourcing of liquidity and workflow management," said Lee Olesky, CEO of Tradeweb Markets. "Tradeweb has a long history of partnering with market participants to meet their needs with innovation, and with the addition of new technology from CodeStreet, we will continue to drive meaningful change in the evolution of today's corporate bond marketplace."

"For more than a decade, CodeStreet has delivered intelligent workflow and liquidity discovery tools to the fixed income broker dealer community, helping grow revenues and riskless business for our customers," said Howard Pein, CEO of CodeStreet. "In becoming a part of Tradeweb's leading fixed income trading marketplace, our clients will benefit from the significant synergies between their premier offering in price discovery, trade execution and workflow, integrated with our analytics and data processing tools."

Tradeweb continues to build the most complete, global corporate bond marketplace, with growing offerings in Europe, the U.S. and emerging markets. More than 500 buy-side institutions leverage Tradeweb to trade credit, streamlining their operational workflow and improving their execution quality with better pre-trade discovery and efficient protocols. In the U.S., and including Tradeweb Direct, one in every 7 corporate bond trades are currently executed on Tradeweb credit platforms, according to TRACE data. In 2015, more than $200 billion was traded on Tradeweb's corporate bond platforms.
