New stock exchange files application with SEC

Members Exchange (MEMX) filed paperwork to the Securities Exchange Commission to operate as a stock exchange, according to documents made public on Thursday. The stock exchange upstart says it will launch next year if approved by regulators.

Why it matters: MEMX is backed by a slew of Wall Street heavyweights and is hoping to take on NYSE parent company Intercontinental Exchange and the Nasdaq — which dominates the industry — by offering a cheaper platform. But other new stock exchanges haven’t been successful in taking significant market share away from the bigger players.
