Barclays’ dark pool, a non-public trading venue, has overtaken Goldman Sachs to become the second largest in the US after the UK bank rebuilt its electronic equities platform two years ago.

According to the latest figures available, in January Barclays LX dark pool moved into second place for US market share ahead of Goldman Sachs, but still behind Credit Suisse, according to consultant Tabb Group and broker Rosenblatt Securities. Goldman Sachs declined to comment.
