The Bitcoin halving is one of the most anticipated events in crypto, and the most recent one just shook the market. If you're wondering when the last Bitcoin halving happened, here's the short answer: April 19, 2024 — a milestone that's still shaping price action and miner behavior today.

The event cut the block reward in half for the fourth time in Bitcoin's history, dropping it from 6.25 BTC to 3.125 BTC. Below, we break down exactly when it happened, why it matters, and what's next on the calendar.

The April 2024 Halving: The Most Recent Bitcoin Halving

The most recent Bitcoin halving took place on April 19, 2024, at block height 840,000. The event occurs roughly every four years, as programmed into Bitcoin's code by Satoshi Nakamoto back in 2009.

As block 840,000 was mined, the network automatically reduced the reward miners receive for validating a new block from 6.25 BTC to 3.125 BTC. This was the fourth halving in Bitcoin's history and the most-watched one to date, given the asset's growing mainstream presence and surging institutional interest.

Unlike previous halvings, this one played out under a very different macro environment. Spot Bitcoin ETFs had launched in the United States just months earlier, opening the door for institutional capital to flow directly into BTC. That context made the 2024 halving unique — and arguably less dramatic in terms of immediate price swings than the 2020 cycle.

How Bitcoin Halvings Actually Work

Bitcoin's supply is hard-capped at 21 million coins. To release new BTC into circulation at a predictable pace, the protocol reduces the mining reward by 50% every 210,000 blocks — roughly every four years.

Here's the basic mechanics at a glance:

  • Initial reward: 50 BTC per block (2009–2012)
  • First halving: 25 BTC per block (2012)
  • Second halving: 12.5 BTC per block (2016)
  • Third halving: 6.25 BTC per block (2020)
  • Fourth halving: 3.125 BTC per block (2024)

Because the reward is denominated in Bitcoin but miners pay real-world costs — electricity, hardware, labor — halvings squeeze profit margins. The theory goes that if demand stays steady or grows, the reduced new supply should eventually push prices higher. This "supply shock" narrative is what makes halvings so pivotal for long-term bulls.

A Full Timeline of Every Bitcoin Halving

For reference, here's how every halving has played out so far:

  • November 28, 2012 — First halving at block 210,000. Reward cut from 50 BTC to 25 BTC.
  • July 9, 2016 — Second halving at block 420,000. Reward cut from 25 BTC to 12.5 BTC.
  • May 11, 2020 — Third halving at block 630,000. Reward cut from 12.5 BTC to 6.25 BTC.
  • April 19, 2024 — Fourth halving at block 840,000. Reward cut from 6.25 BTC to 3.125 BTC.

Notice the rhythm: roughly four years apart, with slight variations depending on how fast blocks were mined. The schedule is probabilistic, not exact — but it almost always lands within a few weeks of the expected window.

What Happens After Each Halving?

Historically, Bitcoin's biggest bull runs have kicked off several months after a halving, not immediately. The 2012 halving preceded the 2013 rally to over $1,000. The 2016 halving led into the 2017 blow-off top near $20,000. The 2020 halving set the stage for the 2021 peak above $69,000.

Whether that pattern holds post-2024 remains to be seen — but it's the chart every trader is watching as the cycle matures.

What the 2024 Halving Means for the Market

The 2024 halving arrived with Bitcoin already trading well above its previous cycle highs. By the time the event happened, BTC had smashed through its 2021 all-time high of roughly $69,000 and was hovering in the $60,000s.

This is a major shift from past cycles, where halvings preceded the major breakout. The market had effectively priced in the event months in advance, which is why the immediate post-halving action was relatively muted compared to 2020 — there was no surprise, just confirmation.

For miners, the impact was sharper. With revenue per block halved overnight, only the most efficient operations stayed comfortably profitable. Several publicly traded miners trimmed their hashrate, sold BTC reserves, or pivoted toward AI and high-performance compute to manage the squeeze.

For long-term holders, the 2024 halving reinforces the same thesis: Bitcoin's daily new issuance is now lower than ever, while demand drivers — spot ETFs, sovereign adoption, and corporate treasury allocations — continue expanding. That supply-demand dynamic is the bull case in one sentence.

When Is the Next Bitcoin Halving?

If the rhythm holds, the fifth Bitcoin halving should land around April 2028, at block height 1,050,000. The block reward will drop from 3.125 BTC to 1.5625 BTC.

By that point, the vast majority of all Bitcoin that will ever exist will already be in circulation. From then on, miners will lean even more heavily on transaction fees to stay profitable — a structural shift that could reshape network security dynamics for decades.

Key Takeaways

  • The last Bitcoin halving occurred on April 19, 2024, at block 840,000.
  • The block reward dropped from 6.25 BTC to 3.125 BTC.
  • It was the fourth halving in Bitcoin's history, following events in 2012, 2016, and 2020.
  • Unlike prior cycles, the 2024 halving happened after BTC had already hit new all-time highs.
  • The next halving is expected around April 2028, when rewards will fall to 1.5625 BTC.
  • Halvings cut new supply, but price action is driven by demand just as much as scarcity.

Bottom line: the most recent Bitcoin halving isn't ancient history — it's fresh, it just happened, and its effects are still rippling through the market. If history rhymes, the months ahead could matter far more than the day itself.
