Stacks: about 735 BTC bonded in Bitcoin Staking across two rounds

what happened

Crypto Briefing reports that Stacks counts around 735 BTC bonded in its Bitcoin Staking feature across the first two bonding periods on mainnet. The figure appeared in the project's Q3 2026 ecosystem update, released on October 15. The Genesis Bond, opened on September 10, 2026, brought in 230 BTC, while the second bond, which opened around October 10, drew roughly 505 BTC against a capacity of about 500 BTC, so it was effectively full.

The bulk of the second round, about 483 of those roughly 505 BTC, came through Stacking DAO's stBTC liquid staking token. That structure let holders keep their coins in circulation as collateral in various DeFi applications while still earning staking yield, projected at about 3% APY and paid weekly in BTC.

Separately, the update says STX staking rose more than 25% after the PoX-5 hard fork activated on July 30, 2026, with staked tokens climbing from 392 million to 493 million. PoX (Proof of Transfer) has been Stacks' consensus mechanism since 2021; instead of burning energy as Bitcoin miners do, Stacks miners commit BTC, and they have committed over 4,200 BTC since launch. Participating institutions named include 21Shares, HashKey Cloud, UTXO Management and Sypher Capital, and custody integrations came from Fireblocks, Fordefi and Anchorage Digital. Bond 3 is expected around November.

why it matters

For Stacks miners, the economics differ from classic proof-of-work: they commit BTC rather than spend electricity on hashing, so their returns depend on the size of the collateral and the flow of BTC into the system. If a large share of capital, about 483 BTC in the second round, runs through a single liquid provider, that shows how concentrated demand for BTC-denominated yield has become. The source does not disclose these miners' sensitivity to the BTC price or their cost base, so no conclusions can be drawn about hashprice or fleet economics.
