Expected~2028
Every 210,000 blocks the block subsidy is cut in half. This one takes new issuance from 3.125 to 1.5625 BTC per block — a step down in the rate of new supply, not a forecast of price.
Every halving so far
| Year | Block | Reward |
|---|---|---|
| 2012November 28, 2012 | 210,000 | 50 25 BTC |
| 2016July 9, 2016 | 420,000 | 25 12.5 BTC |
| 2020May 11, 2020 | 630,000 | 12.5 6.25 BTC |
| 2024April 20, 2024 | 840,000 | 6.25 3.125 BTC |
Block times vary around the ten-minute target, so the date is an estimate that sharpens as the halving approaches — not a fixed appointment. The halving is a supply event written into Bitcoin’s code, not a guarantee of price. Past cycles moved both ways; past performance never guarantees future results.
FAQ
Straight answers, no hedging.
What is the Bitcoin halving?
Roughly every four years — every 210,000 blocks — the reward miners receive for adding a block to the Bitcoin blockchain is cut in half. It is written into Bitcoin's code and steadily slows the rate of new supply, until the last bitcoin is mined around the year 2140.
When is the next Bitcoin halving?
The next halving happens at block 1,050,000, expected around 2028. Because block times vary around the ten-minute target the exact date drifts, so this page estimates it live from the current block height and sharpens as the event approaches.
What happens to the block reward?
At the next halving the reward drops from 3.125 BTC to 1.5625 BTC per block. Past halvings took it 50 → 25 (2012), 25 → 12.5 (2016), 12.5 → 6.25 (2020), and 6.25 → 3.125 (2024).
Does the halving make the price go up?
No one can promise that. The halving is a supply event, not a price guarantee — past cycles saw large moves both up and down, and past performance never guarantees future results. Treat the countdown as context, not a trading signal.
