According to the Planet Daily, according to the analysis of S&P Global Ratings, the United States' approval of the proposed Ethereum exchange-traded funds, which plan to include staking, may increase the concentration risk of Ethereum. S&P analysts Andrew O'Neill and Alexandre Birry said in a report released on Tuesday: "A U.S. spot Ethereum ETF that includes staking may become large enough to change the concentration of validators in the Ethereum network, whether good or bad. Therefore, it is critical to understand how the choices of ETF issuers drive concentration risks." Analysts predict that the U.S. Securities and Exchange Commission will approve the spot Ethereum ETF as early as May this year-the first deadline for approving such funds. Several companies, including giants such as BlackRock and Fidelity, have applied for spot Ethereum ETFs. Some of these applicants, especially Ark Invest and Franklin Templeton, also aim to generate additional income by staking the underlying Ethereum.
