The New York Block Exchange (NYBX) is a 50/50 joint venture between NYSE Euronext and BIDS Trading to re-aggregate block trading liquidity. The Securities and Exchange Commission approved the venture on January 26, 2009 and it launched on January 29, 2009 as a facility of the NYSE. NYSE filed with the SEC on Feb. 8, 2013 to cease operating NYBX due to lack of volume. 
The partnership with NYSE Euronext was intended to provide liquidity to a wider pool of participants and thus address the problem of fragmentation in the block trading environment. NYSE and BIDS envisioned the New York Block Exchange supporting institutions that wanted to move 10,000 or more shares at a time anonymously by enabling trades to happen at a broader range of potential prices.
