Bitcoin Next Halving: Date, History, and What Happens Before & After Each Halving

Bitcoin halving is one of the most important events in the Bitcoin network. It reduces the number of new Bitcoins created with each block, making new supply increasingly scarce.

The next Bitcoin halving is expected around April 2028, although the exact date cannot be known this far in advance because it depends on Bitcoin's block production.

What Is Bitcoin Halving?

Bitcoin was designed with a maximum supply of 21 million BTC. Approximately every 210,000 blocks, the reward paid to miners for creating a new block is cut in half.

The sequence has been:

Halving Approx. Date Block Reward Before After
1st Nov. 28, 2012 50 BTC 25 BTC
2nd Jul. 9, 2016 25 BTC 12.5 BTC
3rd May 11, 2020 12.5 BTC 6.25 BTC
4th Apr. 20, 2024 6.25 BTC 3.125 BTC
5th ~Apr. 2028 3.125 BTC 1.5625 BTC

The 2024 halving reduced the new Bitcoin supply by another 50%. The next halving will reduce the block subsidy to 1.5625 BTC.

What Happened Before Previous Halvings?

One interesting pattern is that Bitcoin has often experienced significant price appreciation during the broader period leading up to a halving.

However, this does not mean that the halving automatically causes Bitcoin to rise immediately.

2012 Halving

The first Bitcoin halving occurred in November 2012.

Bitcoin was still a very small market at that time. After the halving, Bitcoin eventually entered a major bull market, culminating in the huge 2013 rally.

The important point is that the strongest move did not happen immediately on the halving day.

2016 Halving

The second halving occurred on July 9, 2016.

The mining reward decreased:

25 BTC → 12.5 BTC

Bitcoin was already recovering and gaining momentum before the halving.

After the halving, Bitcoin gradually accelerated and eventually entered the famous 2017 bull market.

Bitcoin went from roughly the hundreds of dollars to almost $20,000 at the 2017 peak.

Again, the biggest move occurred months after the halving, rather than immediately.

2020 Bitcoin Halving

The third halving occurred on May 11, 2020.

The reward changed:

12.5 BTC → 6.25 BTC

The timing was particularly interesting because the global economy was dealing with the COVID-19 pandemic.

Bitcoin initially experienced enormous volatility in 2020.

After the halving, however, Bitcoin entered a powerful bull market.

The price eventually reached approximately:

$69,000 in November 2021

This was roughly 18 months after the 2020 halving.

2024 Bitcoin Halving

The fourth halving happened on April 20, 2024, at block 840,000.

The block reward changed:

6.25 BTC → 3.125 BTC

This halving was different from previous cycles because Bitcoin had already reached a new all-time high before the halving, helped in part by the launch of U.S. spot Bitcoin ETFs earlier in 2024.

Bitcoin subsequently reached a new all-time high above $100,000 later in 2024.

This demonstrates something important:

Every Bitcoin cycle is different.

The halving is an important supply event, but Bitcoin's price is also influenced by liquidity, institutional demand, ETFs, interest rates, regulation, investor sentiment and the broader economy.

What Happens to Bitcoin Supply After a Halving?

This is the fundamental reason halvings matter.

Before the 2024 halving:

6.25 BTC × ~144 blocks/day ≈ 900 BTC/day

After the 2024 halving:

3.125 BTC × ~144 ≈ 450 BTC/day

After the expected 2028 halving:

1.5625 BTC × ~144 ≈ 225 BTC/day

So approximately:

2024 → ~900 BTC/day → ~450 BTC/day

2028 → ~450 BTC/day → ~225 BTC/day

The exact daily number varies because Bitcoin does not produce exactly 144 blocks every day.

Why Can Halving Affect Bitcoin's Price?

Imagine that miners collectively receive around 450 new BTC per day after the 2024 halving.

If miners sell a significant portion of those coins, the market has a certain amount of potential selling pressure.

After the 2028 halving, the newly created supply will fall to approximately 225 BTC per day.

If demand remains strong or increases while newly created supply decreases, the supply-demand balance can become more favorable for price.

But there is an important caveat:

Lower supply does not guarantee a higher price.

If demand falls substantially, Bitcoin can still decline after a halving.

What Usually Happens Immediately After a Halving?

A common misconception is:

"Halving happens → Bitcoin immediately goes up."

Historically, it has not worked that simply.

The typical pattern has been more like:

Halving → consolidation/volatility → increasing demand → bull market → major price expansion → cycle peak → bear market

The time between the halving and the eventual cycle peak has historically been measured in many months.

That is why investors often study the entire halving cycle, rather than just the halving date.

Bitcoin's Historical Halving Cycle

A simplified historical picture looks like this:

2012

Halving
↓
Increasing adoption
↓
2013 bull market
↓
Major correction

2016

Halving
↓
Growing demand
↓
2017 bull market
↓
2018 bear market

2020

Halving
↓
Supply reduction
↓
2020–21 bull market
↓
2022 bear market

2024

Halving
↓
Supply reduced again
↓
New market conditions
↓
Future cycle still developing

What Could Happen Before the 2028 Halving?

The period leading toward 2028 could be particularly interesting.

Bitcoin's new issuance will continue decreasing as the network approaches block 1,050,000.

Investors may begin positioning for the next supply reduction well before the actual halving.

However, Bitcoin could also experience several major corrections during this period.

Therefore, a halving should not be treated as a guaranteed trading signal.

The 2028 Bitcoin Halving

The fifth halving is expected around April 2028, at approximately block 1,050,000.

The mining reward will become:

3.125 BTC → 1.5625 BTC

That means Bitcoin's annual new issuance will become even smaller.

Approximately 164,000 BTC per year are created at the current post-2024 rate, while after the 2028 halving this will fall to roughly 82,000 BTC per year, assuming block production remains close to its long-term average.

Will Bitcoin Reach $200,000 or $500,000 After the Next Halving?

Nobody can know.

Historical halvings provide useful information, but they don't provide a guaranteed price target.

For example, the market today is dramatically different from 2012 or 2016.

Bitcoin now has:

Institutional investors
Spot ETFs
Much larger global liquidity
Greater regulatory involvement
Professional derivatives markets
Much larger market capitalization

Therefore, future returns could be very different from previous cycles.

The Most Important Lesson From Previous Halvings

The biggest lesson isn't that:

"Halving = Bitcoin goes up."

The more accurate lesson is:

"Halving permanently reduces Bitcoin's rate of new supply, while price ultimately depends on the relationship between supply and demand."

Historically, Bitcoin's strongest bull-market periods have occurred after halvings, but there is no fixed timetable or guaranteed percentage increase.

Bitcoin Halving Timeline

2009: Bitcoin launches — 50 BTC block reward

2012: 1st halving — 25 BTC

2016: 2nd halving — 12.5 BTC

2020: 3rd halving — 6.25 BTC

2024: 4th halving — 3.125 BTC

~2028: 5th halving — 1.5625 BTC

~2032: 6th halving — 0.78125 BTC

Eventually, Bitcoin's block subsidy will become extremely small, and around the year 2140, the last Bitcoin is expected to be mined. At that point, miners will rely primarily on transaction fees rather than newly created BTC.

Bottom Line

The 2028 halving will be another major milestone in Bitcoin's fixed-supply monetary system. If historical patterns continue, the years surrounding the halving could be extremely important—but past performance is not a guarantee of future returns.

The most useful way to study the next cycle is to examine Bitcoin's price, supply issuance, miner selling, ETF/institutional demand, liquidity and the timing of previous cycle tops and bottoms together, rather than relying on the halving alone.
