ETH is being boosted by favorable regulatory developments that appear to indicate the spot Ether ETF is more likely to be approved by the SEC after regulators asked exchanges to update their 19b-4 filings proposing regulatory changes. As a result, Ether’s implied volatility curve, which indicates market expectations for future volatility across various strikes and expirations, flattened as traders bought $4,000 worth of $24 calls at a year-to-date high of over 18% with a 25-delta risk reversal. Presto Research analysts wrote in May and on May 31. Polymarkets contracts asking whether an Ether ETF will be approved by May 31 jumped from 10 cents to 55 cents, giving it a 55% chance of approval by then.
