Getting a seat at the Bittensor table just got a lot more expensive. The cost to register a new subnet on the decentralized AI network jumped from 230 TAO to 1,500 TAO around May 12, a 6.5x increase that values a single registration slot at roughly $470K.
Bittensor doesn’t set subnet registration fees by committee vote or governance proposal. The cost is determined by a dynamic pricing algorithm that doubles with each successful registration, then slowly decays over time if no one registers. The network caps active subnets at 128, and the demand to claim one of those slots is outpacing the rate at which they open up.
That locked TAO isn’t burned. Registrants can recover it, but only after deregistering their subnet. So while the tokens aren’t permanently destroyed, they’re effectively removed from circulation for as long as the subnet is active. Approximately 73% of all TAO currently in circulation is staked across the network, which further squeezes the liquid supply available on exchanges.
Supply pressure meets the halving
The registration cost spike arrives roughly five months after Bittensor’s December 2025 halving event, which cut daily TAO emissions to 3,600 tokens per day — half the new supply the network was generating before the halving.
Subnet-specific alpha tokens have reached a cumulative market capitalization near $1.5 billion as of early 2026. Select subnets are reportedly generating tens of thousands of dollars in daily revenue through services like AI inference and compute.
What this means for the decentralized AI race
The Bittensor network has plans to expand capacity from 128 to 256 active subnets, which would theoretically ease the registration bottleneck. At $470K per slot, casual experimenters and underfunded projects get priced out, concentrating participation among operators with sufficient capital to bet nearly half a million dollars on their subnet generating meaningful returns.
For TAO holders specifically, the combination of reduced emissions post-halving, 73% staking rates, and escalating registration costs creates a supply profile that’s increasingly constrained.
