Nasdaq Inc. /zigman2/quotes/205547889/composite NDAQ -0.21% is teaming up with a group of banks to spin out its marketplace for shares of private companies, in a move that could help drive more deals to Nasdaq Private Market, the Wall Street Journal reported Tuesday. The banking group includes Goldman Sachs Group Inc. /zigman2/quotes/209237603/composite GS -1.31% and Morgan Stanley /zigman2/quotes/209104354/composite MS -0.55% , as well as SVB Financial Group /zigman2/quotes/200548254/composite SIVB +1.77% , parent of Silicon Valley Bank, the paper reported. Trading in such pre-IPO shares have increased in recent years as startups wait longer to go public, while their employees seek to cash out earlier and investors look to get in on a deal from the ground up. The deal is to be announced later Tuesday. Nasdaq Private Market will be shifted to a separate stand-alone company with investments from the banks. Nasdaq shares were up 2.2% premarket and have gained 33% in the year to date, while the S&P 500 /zigman2/quotes/210599714/realtime SPX -0.16% has gained 13%.
