币界网报道：CBOE Files for 'Pengu' ETF, Sparking 2,250% Surge in Meme Coin The Chicago Board Options Exchange (CBOE) has filed with the U.S. SEC to list the Pengu ETF, a proposed fund tied to the Solana-based meme coin Pengu. The filing triggered a massive 2,250% price surge for the token, which had previously struggled with low liquidity. The Pengu team confirmed the filing but noted the SEC has not yet approved the ETF. If greenlit, the Pengu ETF would be among the first meme coin-based exchange-traded funds, following similar proposals like the Shiba Inu ETF. Analysts caution that the filing doesn’t guarantee approval, as the SEC has historically been skeptical of meme assets. Meanwhile, Pengu’s trading volume spiked 5,000% amid speculative interest. The token’s developers emphasized that the ETF filing is part of broader efforts to establish Pengu as a "utility-driven meme project," though details remain scarce. The news has reignited debates over meme coins' legitimacy in traditional finance.
