Cboe BZX filed a proposed rule change with the SEC to list triple-leveraged Bitcoin and Ether ETFs managed by Volatility Shares, a filing rather than an approval. The timing draws attention because derivatives markets already show crowded long positioning, and adding retail-accessible 3x products into that setup would amplify the liquidation cascades that have defined this summer. Spot Bitcoin ETFs meanwhile posted $56.2 million in net outflows on Friday, with BlackRock's IBIT accounting for nearly all of it.
