Nasdaq has submitted Form 19b-4 to the SEC seeking approval to list and trade shares of Grayscale’s spot Polkadot ETF. The proposed fund, which would track the spot price of Polkadot’s native coin DOT, is expected to trade under the ticker symbol “DOT.” Grayscale Investments, as the sponsor behind the fund, aims to provide investors with a regulated and accessible avenue to gain exposure to Polkadot’s native token. In addition to the spot Polkadot ETF, Grayscale is seeking regulatory nod to offer ETFs tied to other digital assets like XRP, Solana (SOL), Dogecoin (DOGE), Cardano (ADA), and Litecoin (LTC). The 19b-4 form is a crucial regulatory filing required for exchanges to propose rule changes that would allow the listing and trading of newsecurities, such as spot crypto ETFs. Nasdaq’s filing is the second active DOT-focused fund application, following 21Shares’ S-1 registration late last month. Tuttle Capital Management previously proposed a leveraged 2x Polkadot ETF as part of a broader filing for 10 leveraged crypto ETFs. However, shortly after the initial filing, the firm withdrew its proposals for all of its 2x leveraged ETFs. DOT, currently ranked as the 26th largest crypto asset, rose 4% following the ETF filing news, according to CoinGecko data. The token’s market capitalization stands at $6.6 billion.
