Grayscale moves to convert Bittensor trust into first U.S. spot ETF, ticker GTAO

On January 3, 2026, Grayscale filed with the U.S. SEC to convert its Bittensor trust into a spot ETF. The proposal, submitted Tuesday, would list on NYSE Arca under GTAO with Coinbase Custody and BitGo as custodians. After Bittensor's mid‑December halving, TAO later stabilized near $222, according to The Block.
