In an SEC Form 497 filing, the $77.8 billion asset manager also said it would unwind any ether futures purchases it had already made.

The quick backtrack comes after the firm yesterday told CoinDesk (and others) it had begun adding ether futures exposure to the BTF after gaining SEC approval.

Bloomberg ETF analyst Eric Balchunas tweeted that the unwinding of ether futures purchases from Valkyrie is an example of the SEC not wanting to be a “kingmaker via their policies and will do whatever they can to prevent someone from launching on their own like BITO [ProShares Bitcoin Strategy ETF] in 2021.”

Notwithstanding Valkyrie’s actions, it does appear that a number of ether futures ETFs will begin trading in the U.S. on Monday, with ProShares, Bitwise and VanEck among those confirming as much in SEC filings on Friday morning.

Valkyrie did not immediately respond to CoinDesk’s request for comment.
