Standard & Poor's Global Ratings analysis indicates that if the proposed Ether-backed ETF is approved, it could increase concentration risk within the Ethereum network. Analysts Andrew O'Neill and Alexandre Birry mentioned in their report that this ETF could potentially become large enough to alter the concentration of validators in the Ethereum network. They emphasize the importance of understanding how the choices made by ETF issuers can impact concentration risk. Additionally, analysts predict that the U.S. Securities and Exchange Commission may approve the Ether-backed ETF as early as May this year, marking the first deadline for approving such funds.
