The SEC might approve a spot Ethereum ETF as early as this week, indicating a significant regulatory shift. Bloomberg analysts Eric Balchunas and James Seyffart have raised their approval odds to 75% from 25%, based on recent discussions and the SEC’s request for revised 19b-4 filings by Tuesday morning. This development has prompted a rush among applicants, including major firms like BlackRock, Grayscale, and Fidelity.

BlackRock, the largest asset manager globally, has a strong track record with the SEC, with only one ETF application denied in 2014. That ETF, the BlackRock Total Return ETF, was initially rejected over transparency and NAV alignment concerns but was later approved in December 2023. This history highlights BlackRock’s ability to navigate regulatory challenges effectively.

The SEC's decision on Ethereum ETFs has been highly anticipated, with several application deadlines nearing. Data from Bloomberg Terminal shared by James Seyffart lists pending ETFs from VanEck, ARK 21Shares, Hashdex, Grayscale, Invesco Galaxy, Fidelity, Franklin, and Bitwise. Despite multiple delays, the recent push for updated filings suggests a potential breakthrough.

Grayscale and BlackRock have actively updated their applications. Grayscale filed an S-3 registration to convert its existing Ethereum Trust to a spot ETF and an S-1 for a smaller Ethereum ETF. BlackRock’s Nasdaq amendment to its 19b-4 filing proposes cash-based creations and redemptions, aligning with other Ethereum ETF applications and previously approved Bitcoin ETFs.

The SEC’s cautious approach has been due to concerns about market manipulation and the need for comprehensive market data on Ethereum. However, the approval of spot Bitcoin ETFs earlier this year and the launch of spot Ethereum ETFs in Hong Kong have raised expectations for similar Ethereum products. The SEC’s recent interactions with ETF issuers have been described as one-sided, leading to speculation about potential rejections.

Despite these challenges, the crypto community remains optimistic, with Ethereum rising 17% in the past 24 hours. Approval of a spot Ethereum ETF would provide a regulated way for investors to gain exposure to Ethereum, potentially increasing market liquidity and stability. The involvement of asset managers like BlackRock and Fidelity adds credibility, possibly attracting institutional investors and driving further cryptocurrency adoption.

While not guaranteed, BlackRock’s history of overcoming regulatory hurdles suggests favorable odds this week. An Ethereum ETF approval would mark a significant step in crypto’s mainstream integration.
