Grayscale will have the TAO of its Bittensor trust held by two houses in future instead of one. The asset manager has added Coinbase Prime as a second custodian, with BitGo remaining primary custodian. The move is set out in an 8-K that the trust filed with the US Securities and Exchange Commission on 5 October 2026. For holders of Bittensor, this is not price news but news about the question of who holds the keys.
The price itself has a weak week behind it. TAO trades at $275.96, which is 10.7 percent below the highest daily value of the past seven days, according to CoinGecko as of Friday, 9:00. Over seven days it shows a loss of 11.99 percent, over 30 days a gain of 6.39 percent. Taken together, the two describe a pullback inside a month that is still in positive territory on balance.
An 8-K is the mandatory filing with which an issuer registered with the SEC discloses a material event between two quarterly reports. In it, the Grayscale Bittensor Trust reports two contracts signed and one contract terminated, all dated to the end of the month.
On 29 September 2026, the sponsor signed an amendment to the Coinbase Prime Broker Agreement of 3 October 2025 on behalf of the trust. Coinbase will thereby hold a portion of the trust's TAO. A day later, on 30 September, an amendment followed to the revised custody agreement with BitGo Bank & Trust of 5 June 2026, which brings the trust into that agreement. The older BitGo agreement of 12 March 2025 was terminated on the same day.
One figure the document expressly does not name: how much TAO moves to Coinbase has not yet been determined by the sponsor, by its own account. Anyone reading a split in percent over the coming weeks should check where it comes from, because it does not come from this filing. What is recorded, by contrast, is that the custodians' fees are borne by the sponsor and that fees and expenses are taken in TAO.
Computing power is the good settled across the Bittensor network. The custody question leaves that power untouched and applies to the tokens that change hands along the way.
The division of roles remains clear. BitGo is and remains the trust's primary custodian; Coinbase joins as a second address. In the language of institutional custody that means a portion of the holdings will sit in a second infrastructure, with its own keys, its own approval paths and its own operations team.
Prime broker is not a synonym for custodian here. A prime broker agreement bundles trading, settlement and custody with one provider so an institutional client can move large quantities without maintaining a separate relationship for every step. The fact that the trust extended precisely that agreement points to trading capability, not storage alone.
With a single custodian, everything hangs on one operation. If it fails, the fund stands still, regardless of how healthy the assets inside it are. Two custodians spread that operational outage across two mutually independent houses. The risk has not vanished as a result; it is divided.
Set against that is the second route of attack. Every additional infrastructure brings its own keys, its own staff and its own software, and any of those can become the point of entry. The hacks of 2026 repeatedly hit the software around the edges rather than the cryptography itself. Whether the split is a gain is therefore decided by the quality of the second house, not by the number two.
The Grayscale Bittensor Trust runs under the ticker GTAO and trades over the counter, not on a regular US exchange. Grayscale has set out on the road to an exchange-traded fund: the S-1 registration statement reached the SEC on 30 December 2025, and a first amendment followed on 2 April 2026. No approval has come of it to date.
The difference is practical for you rather than academic. A trust traded over the counter can sit permanently above or below the value of its holdings, because the mechanism that continuously creates and redeems shares in an ETF is missing. Anyone who equates such structures with a spot ETF is buying something other than what they think. How the product types diverge in Germany is unpicked in the overview of crypto ETFs for investors in Germany.
Then there is the distribution route. A trust registered in the US is not offered to retail investors in Germany; for distribution to retail clients in the EU, the PRIIPs Regulation requires a key information document, which such products do not carry. The news from the 8-K changes none of that and remains information about the market for you, not a way to buy.
The daily values of the week trace a clear arc: $292.09 on 3 October, then four days between $304 and $309 with the peak of $308.88 on 7 October, after that $291.29 on 8 October and $268.40 at the start of 9 October. Over the past 24 hours the low stood at $254.82 and the high at $287.30. All values according to CoinGecko, as of Friday, 9:00.
For context: market capitalisation stands at around $3.13 billion, trading turnover of the past 24 hours at around $308 million. TAO is 63.6 percent away from its all-time high of $757.60 from March 2024. The week's pullback therefore falls into a phase that already runs far below the old record.
Bittensor is capped at 21 million units, as Bitcoin is. Of those, 11,339,646 TAO are in circulation, or 54.0 percent of the maximum. Issuance declines in steps over time, and the timing of the next step depends on the quantity issued rather than on a calendar date. There is no documented date for it at present, and a forecast would be guesswork.
Institutional custody is above all an operation: separate control desks, separate keys, separate logs.
A subnet on Bittensor is a self-contained competition in which providers deliver a particular service, a language model or data preparation for instance, and are rewarded according to assessed quality. The network's issuance is distributed across these subnets, and anyone holding or delegating TAO is economically tied to that distribution.
For the custody question this matters more than it sounds. Delegating TAO rather than merely holding it puts it into a process that requires active use of keys. Between “sitting in a custodian's vault” and “working in the network” lies a noticeable difference in risk profile, and that holds whether a fund or a private individual holds the tokens.
If you want exposure to TAO in Germany, the route runs through a trading platform licensed under MiCA, or through a certificate on the token authorised in the EU. The US structure from the 8-K is not open to you. Which platforms can show a MiCA licence is set out in the overview of regulated crypto exchanges.
After the purchase comes the same question Grayscale has just answered for itself: who holds the keys. Leave the tokens on the exchange and you carry its operational risk. Withdraw them and you carry it yourself, but the counterparty risk disappears. Which device suits that depends on how much you hold and how often you move the balance.
Two further points belong in the review. Leveraged products on a token that gives up double digits inside a week liquidate quickly; on a decline of 10.7 percent from the weekly high, a ten-times leveraged position is already finished on paper. And for tax, the one-year holding period for private disposals still applies in Germany, whose abolition is under discussion but has not been decided. Spreading several purchases across the year calls for a clean record of the acquisition dates.
Above, the next documented point of orientation lies at the weekly high of $308.88, below that the round level of $300. On the downside, the 24-hour low of $254.82 marks the last place where buyers appeared again, followed by the round 250. These are observation points from this week's price data and not price targets.
What the custody news means for the price cannot be quantified in good faith. An amendment to agreements on custodians is a structural event with no immediate effect on supply or demand. Selling it as a price driver overstretches it.
