BlackRock (BLK), the world’s largest asset manager, hasfiled an S-1 formwith the U.S. Securities and Exchange Commission (SEC) for its iShares Ethereum Trust, a spot ether exchange-traded fund (ETF).

This movefollows last week'scorporate registration of that name and Nasdaq's filing of a 19b-4 with the SEC seeking approval for the spot ETF.

The price of ether(ETH)briefly jumped nearly 2% to $2,080 on the S-1 filing but has since returned to roughly its price prior to the news.

Crypto prices have been responding swiftly to ETF-related updates, particularly after court rulings against the SEC’s rejection of spot crypto ETF applications in the last few months improved market hopes for approval. A spoof iShares ETF registration referencing XRP sentthe token rallying 10% beforeBlackRock said it was fake.

Along with several other asset managers, BlackRock currently is awaiting word from the SEC on listing a spot bitcoin ETF that could open up average investor access to the crypto dramatically. Company CEO Larry Fink has apparently done a complete u-turn on crypto,recently expressing support for the sector.
