Bitcoin Halving Explained: The Next Halving and What Four Cycles Show
The next bitcoin halving is expected in early-to-mid April 2028, when block 1,050,000 is mined and the block subsidy falls from 3.125 BTC to 1.5625 BTC. As of October 23, 2026 the chain sits at block 972,755, leaving 77,245 blocks — about 536.4 days, or 17.6 months, at ten minutes a block. Published countdowns disagree on the date by about nine days; the section below shows why. For a countdown that updates with the chain rather than with this page's last edit, see the bitcoin halving countdown.
The market context matters for how you read the rest of this page. Bitcoin traded at $81,642 on October 23, 2026, 35.3% below its all-time high of $126,198 set on October 6, 2025 — 12.6 months earlier. The fourth halving cycle peaked 17.5 months after its halving and has spent the 12.6 months since below that peak. Any guide still describing this as a post-halving bull phase is out of date.
This guide covers when the next halving lands, how the mechanism works, what happened in each of the four completed cycles, how much supply is left, and what the record does and does not support. For how large a bitcoin position should be before any of this matters, start with the crypto portfolio strategy guide.
This is educational analysis, not financial advice. Bitcoin has fallen more than 70% from a cycle high three times in its history, and no regulator can delay, cancel or reschedule a halving. Past halving cycles do not predict future ones.
What to know about the next bitcoin halving
The next bitcoin halving is expected in early-to-mid April 2028, when block 1,050,000 is mined and the block subsidy drops from 3.125 BTC to 1.5625 BTC. As of October 23, 2026 that is 77,245 blocks away, about 17.6 months. The date is an estimate and published trackers disagree by about nine days, because halvings fire on block height and block times vary with hash rate.
| What | Value as of October 23, 2026 | Why it matters |
|---|---|---|
| Estimated date | Early-to-mid April 2028 | Trackers give April 8 to April 17; the block, not the date, is the fixed fact |
| Trigger | Block height 1,050,000 | Halvings fire every 210,000 blocks on height, never on a date |
| Blocks remaining | 77,245 | At roughly ten minutes a block, about 536.4 days or 17.6 months |
| Current block height | 972,755 | 132,755 blocks into the current 210,000-block epoch — 63.2% through |
| Subsidy before | 3.125 BTC per block | Set by the April 2024 halving |
| Subsidy after | 1.5625 BTC per block | New issuance falls from about 450 BTC a day to about 225 |
| Annual issuance now | About 164,250 BTC | 450 BTC a day against a mined supply near 20.10 million |
| Annual issuance after April 2028 | About 82,125 BTC | The supply base barely moves, so the rate roughly halves |
| Current annual issuance rate | About 0.82% | 164,250 divided by about 20.10 million |
| Issuance rate after April 2028 | About 0.40% | Already under 1%, so each halving matters less in absolute terms |
The estimated date moves. If the network hash rate rises, blocks are found faster than ten minutes on average and the halving arrives earlier; if hash rate falls, it arrives later. Treat early-to-mid April 2028 as a window that will drift by days, and treat block 1,050,000 as the only fixed fact.
When is the next bitcoin halving date?
There is no fixed next bitcoin halving date, and the published estimates disagree. As of October 23, 2026 the trackers span April 8 to April 17, 2028 — about a nine-day spread — because each one projects a different average block time across the 77,245 blocks remaining. Block 1,050,000 is the only fixed fact; every calendar date is a forecast derived from it.
| Source | Estimated date | Basis stated by the source |
|---|---|---|
| CoinWarz | April 8, 2028, 00:53 UTC | A 9 minute 56 second average block time over the last 20,160 blocks |
| CoinGecko, page header | April 11, 2028, 21:40 | Not stated |
| CoinGecko, page body and table | April 17, 2028 | Not stated; the same page gives two different dates and does not explain the difference |
| Plain ten-minute arithmetic | About April 12, 2028 | 77,245 blocks remaining times ten minutes, from October 23, 2026 |
All four read on October 23, 2026.
Blocks are found faster than ten minutes when hash rate rises and slower when it falls. A tracker using a recent fast average projects an earlier date; one using the protocol's ten-minute target projects a later one. Neither is wrong, and neither is authoritative.
These estimates move day to day. CoinGecko's own header figure read April 12, 2028 at 03:12 on October 22, 2026 and April 11, 2028 at 21:40 a day later. Over 77,245 remaining blocks, a four-second change in the average block time moves the estimate by roughly three and a half days.
Treat early-to-mid April 2028 as the window and block 1,050,000 as the event. Any plan that depends on the halving landing in a specific week is built on a forecast of future hash rate, which nobody has.
When does bitcoin half, and what is the btc halving countdown?
Bitcoin halves every 210,000 blocks, which averages close to four years. The last halving was April 19-20, 2024 at block 840,000, and the next is block 1,050,000, expected in early-to-mid April 2028. As of October 23, 2026 the countdown stands at 77,245 blocks.
How to compute this yourself
- Find the current block height on any block explorer.
- Subtract it from 1,050,000. That is the blocks remaining.
- Multiply by ten minutes. That is the approximate time left. On October 23, 2026: 1,050,000 − 972,755 = 77,245 blocks, or about 536.4 days.
Countdown clocks disagree with each other by days because each uses a different recent-average block time. None of them is authoritative and none of them can be, because the date is an output of future hash rate. The block height is the fact; the date is a forecast. The date section above compares four published estimates as of October 23, 2026 and shows the nine-day spread between them.
Bitcoin halving explained: how does the halving work?
A bitcoin halving cuts the block subsidy — the newly created bitcoin paid to whoever mines a block — in half. It happens automatically every 210,000 blocks, is written into the protocol's consensus rules, and requires no vote, no announcement and no coordination. It is the mechanism that enforces the 21 million supply cap.
The subsidy started at 50 BTC in January 2009 and has halved four times: to 25, 12.5, 6.25 and 3.125 BTC. It will keep halving roughly every four years until the subsidy rounds to zero, which is expected around 2140 after roughly 29 more halvings.
Miners are paid twice: the block subsidy and the transaction fees in the block. The halving cuts only the subsidy. As of September 2026 transaction fees averaged 0.0199 BTC per block, about 0.63% of total block rewards, so fees are nowhere near replacing the subsidy today. As the subsidy shrinks toward zero, fees must carry a growing share of the security budget — an unresolved long-term question, not a solved one.
Stock-to-flow is the ratio of existing supply to annual new supply. It doubles at every halving by construction. CryptoBull does not use stock-to-flow to set price targets.
What is the bitcoin halving cycle, and what happened at each bitcoin halving event?
Four halvings have occurred — November 2012, July 2016, May 2020 and April 2024 — and each was followed by a cycle peak 12 to 18 months later. The peaks have grown, but by progressively smaller amounts: plus 1,645%, then plus 251%, then plus 82.8% over the prior peak.
| Halving | Date | Block | Subsidy | Cycle peak that followed | Peak date | Months to peak |
|---|---|---|---|---|---|---|
| 1st | November 28, 2012 | 210,000 | 50 → 25 BTC | $1,127 | November 30, 2013 | 12.1 |
| 2nd | July 9, 2016 | 420,000 | 25 → 12.5 BTC | $19,665 | December 16, 2017 | 17.2 |
| 3rd | May 11, 2020 | 630,000 | 12.5 → 6.25 BTC | $69,044 | November 10, 2021 | 18.0 |
| 4th | April 19–20, 2024 | 840,000 | 6.25 → 3.125 BTC | $126,198 | October 6, 2025 | 17.5 |
| 5th | Early-to-mid April 2028 (est.) | 1,050,000 | 3.125 → 1.5625 BTC | Unknown | — | — |
Peak prices from CoinMarketCap data as reported August 2026. Halving dates are the dates the trigger block was mined. The April 2024 halving is dated April 19 or April 20 depending on time zone; block 840,000 was mined just after midnight UTC on April 20.
| Cycle | Peak | Growth over the previous peak |
|---|---|---|
| 2013 | $1,127 | — |
| 2017 | $19,665 | +1,645% |
| 2021 | $69,044 | +251% |
| 2025 | $126,198 | +82.8% |
This is the most important pattern on the page and it points the opposite way from the usual halving argument. Each cycle has produced a higher peak and a smaller multiple. If that decay continues, the next cycle peak would be a far smaller percentage gain than the last — and three data points are not enough to extrapolate from with any confidence in either direction.
Cycle four is now 12.6 months past its peak as of October 23, 2026, with bitcoin 35.3% below the October 6, 2025 high of $126,198. For scale, the halving-to-peak interval across the four completed cycles was 12.1, 17.2, 18.0 and 17.5 months. The time already spent below this cycle's peak is comparable to the time it took to reach it.
Bitcoin supply mined, circulating supply, and halving impact
About 20.10 million of the 21 million bitcoin cap had been mined as of October 23, 2026 — roughly 95.7% of total supply — leaving about 900,000 coins to be issued over the next century or so. The 20 millionth coin was mined at block 940,000 around March 9, 2026.
| Supply measure | Value as of October 23, 2026 | Note |
|---|---|---|
| Total cap | 21,000,000 BTC | Fixed by consensus rules |
| Mined to date | About 20.10 million BTC | 20 million at block 940,000 plus 102,359 from the 32,755 blocks since, at 3.125 BTC each |
| Share of cap mined | About 95.7% | Reached in under two decades |
| Remaining to mine | About 900,000 BTC | Expected to take until roughly 2140 |
| Daily issuance | About 450 BTC | 3.125 BTC × roughly 144 blocks a day |
| Annual issuance | About 164,250 BTC | 450 × 365 |
| Annual issuance rate | About 0.82% | Against a mined supply near 20.10 million |
| Rate after April 2028 | About 0.40% | Subsidy halves; the supply base barely moves |
The mined figure is derived from a reported 20.07 million as of August 16, 2026 and the block subsidy issued since; confirm against a live supply chart before relying on the last decimal place.
The halving's supply effect gets structurally weaker every time, and the arithmetic is the reason. The 2012 halving removed 25 BTC per block from issuance against a supply of about 10.5 million. The 2028 halving removes 1.5625 BTC per block against a supply above 20 million. Each halving cuts the issuance rate in half, but that rate is already below 1%, so the absolute change in new supply keeps shrinking.
Mined supply is not the same as available supply. An unknown quantity of bitcoin — estimates vary widely and none is verifiable — is permanently lost to discarded keys. This page does not put a number on it.
Does the halving actually cause bull markets?
Every completed halving has been followed by a cycle peak within 12 to 18 months, which is four for four. That is a real pattern and it is also four observations, in a period during which bitcoin went from an experiment to an institutionally held asset — so the halving is confounded with adoption, liquidity conditions and monetary policy on every one of them.
- Four data points cannot separate causes. Every halving cycle coincided with a distinct macro regime, and no cycle isolates the halving from everything else that changed.
- The event is fully known in advance. The date and the exact block are public years ahead, so an efficient market should price the supply change before it happens rather than after.
- The supply effect is shrinking. The 2028 halving removes roughly 82,000 BTC a year from issuance against a market that trades far more than that daily.
- The peaks are decaying. Plus 1,645%, then plus 251%, then plus 82.8% — the pattern that is most consistent across cycles is diminishing returns, not repeating ones.
The honest position is that the halving is a real and permanent change to bitcoin's issuance, that it has coincided with four bull markets, and that nobody can demonstrate which of those things caused the others. Treat cycle history as context for setting expectations, not as a schedule to trade against.
What does the regulatory environment change about the next halving?
Nothing in the halving itself is subject to regulation. It is a consensus rule that fires on block height, and no regulator, government or exchange can delay, cancel or reschedule it. What regulation does affect is everything around it: whether miners can bank and buy power, how a cycle exit is taxed, and what instruments hold bitcoin on the way up and down.
- The event itself is untouchable. The subsidy schedule is enforced by consensus rules, not by any institution. This is the one feature of bitcoin that no policy change can alter.
- Banking access for digital-asset businesses is an open issue. On October 14, 2026 the OCC reported that all nine of the largest national banks it supervises maintained policies between 2020 and September 2025 that may have restricted access to financial services on political, religious or lawful-business grounds, and it named digital asset activities among the affected sectors. The review covered about 100,000 complaints and about 420,000 pages of bank documents.
- Mining economics are policy-exposed in a way the halving is not. Power pricing, grid rules and local permitting decide which miners survive a subsidy cut. The halving sets the revenue; policy sets the cost.
- A cycle exit is a taxable event before it is anything else. See the crypto tax guide for Form 1099-DA and per-wallet basis treatment of the disposals a cycle exit creates.
The practical reading is that the regulatory environment changes who can hold and mine bitcoin through a halving cycle, and what it costs them, but not when the halving happens or what it does to issuance. Those two things are fixed.
What are the risks and misconceptions about crypto market halving?
The four most costly halving misconceptions are that the halving guarantees a price rise, that its effect is immediate, that mining collapses afterwards, and that the cycle runs on a calendar. Each is wrong in a way that leads to a specific, repeatable mistake.
| Misconception | What the record shows | The mistake it causes |
|---|---|---|
| "The halving guarantees a price increase" | Four cycles is not proof of causation, and the peak multiple has fallen every cycle | Position sizing built on a guaranteed outcome |
| "The effect is immediate" | Cycle peaks came 12.1, 17.2, 18.0 and 17.5 months after the halving, not days | Buying the event and selling the disappointment weeks later |
| "Mining becomes unprofitable and the network breaks" | Difficulty adjusts roughly every two weeks; less efficient miners exit and the network continues | Treating a hash-rate dip as a network failure |
| "The cycle runs on a four-year calendar" | Halvings fire on block height, and the peak-to-peak interval has varied by six months | Anchoring an exit to a date rather than to a plan |
| "This time is different" | The 2024 cycle was the first with spot ETFs and it still peaked and rolled over; those flows run both ways — US spot bitcoin ETFs saw a net outflow of $635.6 million on October 22, 2026 | Assuming structural change removes downside |
The risk that matters most is not that the halving fails to produce a rally. It is drawdown. Bitcoin has fallen more than 70% from a cycle high three separate times, and as of October 23, 2026 it sits 35.3% below the October 2025 peak, 12.6 months after it. An allocation that cannot survive that is the wrong size regardless of what the halving does.
For sizing an allocation against a drawdown of that magnitude, see the crypto portfolio strategy guide; for the rules that decide what to trim when a cycle does run, see crypto rebalancing strategies.
What does a halving mean for miners and network security?
A halving cuts miner subsidy revenue in half overnight while costs stay the same, so the least efficient operations become unprofitable and shut down. Network difficulty adjusts roughly every 2,016 blocks to compensate, which restores normal block times within about two weeks. The long-term question is not survival but whether transaction fees can replace a subsidy that keeps halving toward zero.
- Immediate effect: subsidy revenue halves, marginal miners power down, hash rate falls.
- Adjustment: difficulty retargets roughly every two weeks, blocks return to about ten minutes, and the remaining miners earn a larger share.
- Long-term: after the 2028 halving the subsidy is 1.5625 BTC. The security budget increasingly depends on fee revenue, and no one has demonstrated that fees alone are sufficient at scale.
| Measure | Value | As of |
|---|---|---|
| Network difficulty | 140.58 trillion, up 5.92% from 132.72 trillion | Block 971,712, October 16, 2026 |
| Difficulty all-time high | 155.97 trillion | October 29, 2025 |
| Network hash rate | About 1,036 EH/s, above 1 ZH/s every day the prior week | October 17, 2026 |
| Hashprice | $36.75 per PH/s per day, against $37.56 a month earlier | October 16, 2026 |
| Transaction fees | 0.0199 BTC per block, about 0.63% of block rewards | September 2026 average |
| Revenue per MWh, fleet under 14 J/TH | About $137 | September 2026 average |
| Revenue per MWh, fleet at 25 to 38 J/TH | About $51 | September 2026 average |
| Average US industrial power price | About $48 per MWh | September 2026 |
| Next difficulty retarget | Block 973,728 | Around October 30, 2026 |
Difficulty rose 5.92% in a single retarget in October 2026 — the third-largest increase of 2026 — while hashprice fell to $36.75. Miner revenue per unit of work is being squeezed by competition alone, with no halving involved. A halving does the same thing in one step and twice as hard, which is why the least efficient fleets are the ones that exit.
The fee number matters more than the rest. At 0.63% of block rewards, transaction fees are not a meaningful share of miner revenue as of September 2026. The long-term security argument assumes fees grow into the gap as the subsidy halves toward zero; that has not happened yet, and this page does not assume it will.
This page does not recommend mining-equity exposure as a halving trade. Listed miners carry operational, financing and dilution risk that is unrelated to bitcoin's price, and their revenue is the one thing a halving cuts directly and immediately.
How should a long-term investor think about positioning for the next halving?
The defensible positions are the boring ones: decide an allocation you can hold through a 70% drawdown, buy on a schedule rather than around an event, and set your rebalancing rule before the cycle runs rather than during it. Nothing in four cycles of data supports timing an entry to a halving date that is still 17.6 months and 77,245 blocks away as of October 23, 2026.
| Approach | What it is | The honest constraint |
|---|---|---|
| Fixed-schedule buying | A set amount at set intervals regardless of price | Removes timing risk and also removes any chance of timing well; it is a discipline, not an edge |
| Allocation-first sizing | Decide the position size before deciding the entry | The only variable here you actually control, and the one that determines whether you hold through a drawdown |
| Pre-set rebalancing rules | Bands or a calendar, written down in advance | Rules set during a rally get abandoned during a drawdown, which is when they matter |
| Waiting for the halving | Holding cash to deploy near April 2028 | The date is an estimate that trackers already disagree about by nine days, and 17.6 months of opportunity cost is a real cost |
| Mining-equity exposure | Listed miners as leveraged bitcoin proxies | Not covered here. Miner revenue is what the halving cuts, and equity risk is not bitcoin risk |
The record's clearest signal is that cycle peaks arrive 12 to 18 months after a halving and that each peak has grown by less than the last. Both halves of that sentence matter. A plan built only on the first half sizes positions for a repeat of 2021.

El próximo halving de Bitcoin / Das nächste Bitcoin-Halving
¿Cuándo es el próximo halving de Bitcoin?
El próximo halving de Bitcoin se espera entre el 8 y el 17 de abril de 2028, cuando se mine el bloque 1.050.000 y la recompensa por bloque baje de 3,125 BTC a 1,5625 BTC. Al 23 de octubre de 2026 faltan 77.245 bloques, es decir unos 536,4 días o 17,6 meses a diez minutos por bloque. La fecha es una estimación y los contadores publicados no coinciden: el halving se activa por altura de bloque, no por calendario. Bitcoin cotizaba a 81.642 dólares el 23 de octubre de 2026, un 35,3% por debajo de su máximo histórico de 126.198 dólares del 6 de octubre de 2025.
Wann ist das nächste Bitcoin-Halving?
Das nächste Bitcoin-Halving wird zwischen dem 8. und 17. April 2028 erwartet, wenn Block 1.050.000 gefunden wird und die Blockbelohnung von 3,125 BTC auf 1,5625 BTC fällt. Stand 23. Oktober 2026 fehlen noch 77.245 Blöcke, also etwa 536,4 Tage oder 17,6 Monate bei zehn Minuten pro Block. Das Datum ist eine Schätzung und die veröffentlichten Countdowns weichen voneinander ab: Das Halving wird durch die Blockhöhe ausgelöst, nicht durch ein Kalenderdatum. Bitcoin notierte am 23. Oktober 2026 bei 81.642 US-Dollar und damit 35,3% unter dem Allzeithoch von 126.198 US-Dollar vom 6. Oktober 2025.

Frequently asked questions
What to know about the next bitcoin halving?
The next bitcoin halving is expected in early-to-mid April 2028, when block 1,050,000 is mined and the block subsidy falls from 3.125 BTC to 1.5625 BTC. As of October 23, 2026 the chain sits at block 972,755, leaving 77,245 blocks, or about 17.6 months at ten minutes a block. Published trackers place the date between April 8 and April 17, 2028, because the halving fires on block height and block times vary with hash rate.
When is the next bitcoin halving date?
There is no fixed next bitcoin halving date; the event fires when block 1,050,000 is mined. As of October 23, 2026, 1,050,000 minus 972,755 leaves 77,245 blocks, about 536.4 days at ten minutes a block. Published trackers span April 8 to April 17, 2028 as of October 23, 2026, a spread of about nine days, because each projects a different average block time. Block 1,050,000 is the fixed fact and every calendar date is a forecast.
When is the next bitcoin halving?
The next bitcoin halving is block 1,050,000, expected in early-to-mid April 2028, with published trackers ranging from April 8 to April 17, 2028 as of October 23, 2026. As of October 23, 2026 it is 77,245 blocks away, about 17.6 months at ten minutes a block. Halvings occur every 210,000 blocks, and the previous one was April 19-20, 2024 at block 840,000.
What is the next bitcoin halving, and what changes?
The next bitcoin halving is the fifth, at block 1,050,000, expected in early-to-mid April 2028. It cuts the block subsidy from 3.125 BTC to 1.5625 BTC, reducing new issuance from about 450 BTC a day to about 225. As of October 23, 2026 that moves the annual issuance rate from about 0.82% to about 0.40% after the halving. The schedule is a consensus rule that no regulator, government or exchange can delay or reschedule.
What is the btc halving countdown right now?
As of October 23, 2026 the btc halving countdown is 77,245 blocks: 1,050,000 minus the block height of 972,755. At ten minutes a block that is about 536.4 days, or 17.6 months. Published trackers convert that into dates between April 8 and April 17, 2028 as of October 23, 2026, because each uses a different average block time. The block-height arithmetic is the checkable figure; recompute it from any block explorer.

How much bitcoin supply has been mined, and what is the halving's impact on circulating supply?
About 20.10 million of the 21 million bitcoin cap had been mined as of October 23, 2026, roughly 95.7% of total supply, leaving about 900,000 coins to be issued over the next century or so. As of October 23, 2026 annual issuance runs near 164,250 BTC, an issuance rate of about 0.82%. After the April 2028 halving that rate falls to about 0.40%, so each halving changes new supply by less in absolute terms than the one before.
