Grayscale Files to Move Bittensor Trust Toward NYSE Arca

On December 30, 2025, Grayscale Bittensor Trust filed a preliminary Form S-1 with the U.S. Securities and Exchange Commission describing a plan to move its TAO-holding vehicle from OTCQX quotation to an exchange-traded product on NYSE Arca. The shares were to keep the ticker GTAO, while the trust would be renamed Grayscale Bittensor Trust ETF in connection with effectiveness and listing.

The filing was the clearest U.S. institutional-market step yet for Bittensor’s native token. CoinDesk and The Block both described it on December 30 as the first attempt at a U.S.-listed spot product giving direct TAO exposure. That distinction mattered because the proposal extended the crypto-fund pipeline beyond bitcoin and ether into a token associated with decentralized machine-intelligence markets. It was evidence of product ambition, however, not proof of investor demand or regulatory acceptance.

What the filing proposed

The trust said its objective would be to reflect the value of TAO held by the vehicle, less expenses and liabilities. It did not propose to obtain exposure through futures. The preliminary prospectus named Coinbase as prime broker, Coinbase Custody Trust Company and BitGo Trust Company as custodians, and The Bank of New York Mellon as administrator and transfer agent.

The structure was meant to add continuous creations and redemptions through authorized participants. That mechanism is central to an exchange-traded product because arbitrage can pull the share price toward the value of the underlying assets. The existing OTCQX shares lacked an operating redemption program as of December 30, 2025, leaving holders more exposed to premiums or discounts disconnected from the trust’s TAO value.

Grayscale’s own filing quantified that problem. Comparing GTAO’s OTCQX closing price with the trust’s net asset value per share from December 12 through December 26, 2025, it reported a maximum premium of 77% and an average premium of 50%. The premium was 39% on December 26. Those figures describe the quoted trust shares over that limited period; they are not TAO returns, exchange-traded-product performance, or a forecast. The proposed creation-redemption system was intended to reduce such dislocations, but the filing did not guarantee that it would do so.

The boundaries were as important as the ambition

The December 30 document was explicitly preliminary. The SEC had not approved the shares, judged the prospectus complete, or made the registration statement effective. NYSE Arca listing was an intention stated by the sponsor, not an accomplished listing. The product therefore could not be described as launched on December 30, 2025.

Staking was another unresolved feature. The trust agreement allowed staking only after specified conditions were satisfied, and the prospectus said those conditions had not been met. Consequently, the trust was prohibited from staking TAO as of the filing date. That created a potential difference between holding GTAO shares and holding TAO in a way that could participate in network rewards.

The filing also stated that the trust was not registered under the Investment Company Act of 1940 and that Grayscale believed it was not a commodity pool under the Commodity Exchange Act. Those disclosures framed the proposed wrapper’s regulatory boundaries; the familiar ETF label did not make it equivalent to a conventional registered investment company.

Why December 30 mattered

The verified development was not a regulatory green light. It was the conversion roadmap itself: an SEC-filed attempt to connect a smaller, specialized crypto network to U.S. exchange infrastructure, institutional custody and an arbitrage-based share structure. On December 30, 2025, that made GTAO a test of how far the U.S. digital-asset product market might extend beyond its largest assets—and of whether exchange plumbing could narrow the distortions already visible in the OTC trust.
