Several potential issuers of Ether exchange-traded funds (ETFs) have made adjustments to their filings following last-minute feedback from the Securities and Exchange Commission (SEC).

Asset managers Fidelity, VanEck, and Franklin Templeton, along with joint applicants Galaxy and Invesco, and ARK Invest and 21Shares, have all submitted amended 19b-4 filings.

The revisions include the removal of provisions for Ethereum (ETH) staking by Fidelity, Franklin Templeton, and ARK 21Shares.

These changes were reflected in similar language used by other applicants sponsored by the Chicago Board Options Exchange (CBOE).

Grayscale also abandoned staking, as indicated in a proxy statement.

Despite the removal of staking, some experts believe that an approved spot Ether ETF could still enhance staking returns and bolster Ethereum's legitimacy.

All five CBOE filings were lodged within a 25-minute timeframe on May 21, according to Bloomberg ETF analyst James Seyffart.

However, Seyffart emphasized that the approved 19b-4 filings must be accompanied by signed-off S-1 registration statements for the ETFs to proceed towards launch.

While the SEC's decision on VanEck’s application is expected by May 23, industry analysts anticipate a similar approach to multiple applicants, similar to how spot Bitcoin ETFs were handled.

Fox Business reporter Eleanor Terrett noted that VanEck’s Ether ETF bid appeared on the Depository Trust and Clearing Corporation’s (DTCC) website, often indicating eligibility for trading and settlement within its systems, but not necessarily approval by the SEC.

BlackRock and Hashdex are also competing for SEC approval for spot Ether ETFs.

The SEC reportedly requested applicants to expedite their 19b-4 filings starting from May 20, leading Bloomberg analysts to raise their spot Ether ETF approval odds from 25% to 75%.

Since the reported shift in SEC stance, ETH has surged by 20.6% to around $3,800, according to CoinGecko.
