According to @CoinMarketCap, Grayscale Investments has filed with the U.S. SEC to launch the Grayscale Bittensor Trust, which would be the first U.S. exchange-traded product offering exposure to Bittensor’s TAO and is proposed to trade on NYSE Arca if approved (source: @CoinMarketCap). SEC approval requires an exchange rule change for NYSE Arca under Exchange Act Section 19(b) and an effective registration statement, with statutory deadlines that can extend up to 240 days from publication in the Federal Register (source: U.S. SEC). If approved, an NYSE Arca-listed ETP would provide regulated brokerage access to TAO exposure via exchange-traded shares, with listing eligibility and start-of-trading governed by SEC and exchange procedures (source: NYSE Arca; U.S. SEC).
