According to official news, the Bitcoin staking protocol Babylon disclosed that on December 15, during the Cap-3 mainnet staking period, an anonymous staker staked 10,000 Bitcoins through three transactions, valued at over 1 billion dollars.
Babylon stated that prior to this, the largest staking amounts came from entities wishing to stake on behalf of their users (such as LST protocols and custodians), but such a large stake from an individual is significant for Babylon and its protocol.
Previously, on December 17, Babylon announced on X that the Cap-3 mainnet staking had ended, with BTC staked valued at over 6 billion dollars.
