Investment management firm BlackRock has a spot bitcoin exchange-traded fund (ETF) that’s awaiting potential approval by the U.S. Securities and Exchange Commission.

A group of major trading firms are reportedly waiting in the wings to provide liquidity to the fund.

Jane Street, Virtu Financial, Jump Trading and Hudson River Trading have spoken with BlackRok about serving as market makers for the fund, a source told CoinDesk.

In an ETF, market makers create and redeem new shares to keep the price in line with the value of that fund’s holdings.

BlackRock is one of the several prominent firms pursuing a spot bitcoin ETF but it is also considered a frontrunner because of its size. It is the world’s largest asset manager, with about $9 trillion in assets under management.

Earlier this month, a false social media report about BlackRock receiving SEC approval sent the price of bitcoin (BTC) from $27,900 to $30,000. BTC is now at $34,566.90 on continued market optimism.
