The scheduled 50 percent cut in Bitcoin's block reward, roughly every four years.
Every 210000 blocks, the reward paid to Bitcoin miners halves. It went from 50 to 25 to 12.5 to 6.25 to 3.125, and will keep halving until issuance ends around 2140.
The halving is the clock crypto cycles are often measured against, though causation is much debated and every cycle has had other drivers too.
Halvings are fully predictable. Anyone can calculate the exact block years in advance.
That the halving is a price event. It is a supply event with a known date that everyone can read years ahead, which is the opposite of surprising. What it reliably changes is miner economics; what it does to price is argued about after the fact.
