The next Bitcoin halving: what the 2028 cut actually means for miners and price
Block 1,050,000 lands around April 2028, cutting the subsidy from 3.125 BTC to 1.5625 BTC. Daily issuance falls to 225 BTC. Here is how miners, price, and fees actually respond.
The next Bitcoin halving is scheduled for block 1,050,000, projected to land in the second or third week of April 2028 based on current hash-rate trajectory. At that point, the block subsidy drops from 3.125 BTC to 1.5625 BTC, daily new issuance falls from approximately 450 BTC to 225 BTC, and the annualised inflation rate of the supply drops from roughly 0.84% to 0.42% — below the central tendency of gold’s annual mine supply for the first time in Bitcoin’s history. It will be the fifth such event since the genesis block, and the first to occur with mature spot ETFs, a regulated US options complex on those ETFs, sovereign holding programmes in multiple jurisdictions, and a hash-rate exceeding 800 exahashes per second.
What is at stake is whether the historical halving playbook — accumulation in the year before, rally in the 12-18 months after, sharp drawdown thereafter — still applies in a market structure that no longer resembles the one that produced that playbook. The 2012, 2016, and 2020 halvings each occurred against a backdrop of negligible institutional ownership, no regulated derivatives in the US, and a miner cohort that was the dominant marginal seller. By 2028, miners will produce roughly $7.5 billion of new BTC per year at $33,000 spot (lower at lower prices), against ETF inflows that have run at $20-30 billion annualised for two years and a corporate-treasury cohort that buys mechanically rather than tactically. The supply shock is real and measurable; whether it translates into the price action of prior cycles is a separate question.
The miner economics, in dollars per terahash
The relevant unit for miner viability is hashprice — the daily revenue per terahash per second, expressed in dollars. Before April 2024, hashprice ranged $0.08-$0.12 with BTC at $50-70k; after the 2024 halving it compressed to $0.04-$0.06 at similar prices, exactly as the halving math demands. By 2028, with another 50% subsidy cut, hashprice at constant BTC price falls another roughly 45% (the fee share grows slightly, blunting it). At $0.03 per terahash per second, only the most efficient ASIC fleets — current-generation Bitmain S21 Pro and MicroBT M66S, running on power below $0.045/kWh — generate positive operating margin. The marginal miner is forced offline, hashrate compresses, the difficulty adjustment lowers the bar for surviving miners, and equilibrium re-establishes at a smaller, more concentrated network footprint. Public miner equity holders learned this in 2024 and will relearn it in 2028.
Where the fee market sits — and where it needs to go
Transaction fees currently contribute between 4% and 12% of total miner revenue, with significant spikes during congestion events (the Runes launch in April 2024 briefly drove fees to 60% of revenue). Long-term, that ratio must climb structurally — the subsidy halves every four years and asymptotically approaches zero by ~2140. A back-of-envelope: if BTC market cap holds at $1.3 trillion and hashrate stays roughly proportional to security spend, miners need to earn approximately $15 billion per year in 2028 to maintain current security; at 225 BTC daily issuance, the subsidy contributes roughly $9-11 billion at $33-40k spot, leaving a $4-6 billion annual fee gap to fill. Mempool.space publishes the real-time fee distribution; the long-term trend is the question that matters more than the next print.

The price playbook from prior cycles — and its limits
The stylised history is well-known: BTC bottomed roughly 12-18 months before each of the 2012, 2016, and 2020 halvings, rallied through the event without much fanfare, and printed a cycle high 12-18 months after. The peak-to-trough drawdown in each cycle ran 75-85%. That pattern produces excellent narrative but mediocre forecasts: the sample size is three, the underlying market structure changed materially between each iteration, and the 2024 cycle has so far behaved like a continuation of the pre-halving rally that began in late 2022, with the post-halving phase looking less explosive and more grind-higher than 2017 or 2021. Whether 2028 reverts to the historical pattern or completes the maturation toward “normal volatility” is the central macro question. We track the relevant inputs continuously on our halving dashboard.
Who actually sells, and when
Pre-2024 cycle analysis assumed miners were the dominant marginal seller — they receive newly-mined BTC daily, have fiat-denominated operating costs, and historically liquidated 60-90% of production within 30 days. That assumption is now wrong in two directions. First, public miners (Marathon, Riot, CleanSpark, Core Scientific) collectively hold over 115,000 BTC on balance sheet as of late 2025, financed by equity and convertible debt rather than coin sales, and have shifted to a “hold-and-finance” model. Second, the marginal selling pressure now comes from ETF outflows, long-dormant wallets reactivating, and OTC desks unwinding corporate treasury positions — flows that are uncorrelated with mining economics. The 2028 supply shock therefore matters less on the sell side (because miners sell less) than on the demand side (because ETF flows are price-elastic). The arithmetic that mattered in 2016 does not cleanly translate.
The geographical hash-rate reshuffle
China’s 2021 mining ban remapped global hashrate distribution overnight. As of 2025, the US hosts roughly 36-40% of global hashrate, concentrated in Texas (ERCOT grid flexibility), Georgia, and Kentucky. Russia, Kazakhstan, Paraguay, Argentina, and Ethiopia have absorbed most of the displaced capacity. Each halving event triggers another reshuffle as marginal-cost regions push out higher-cost regions: the 2024 halving accelerated migration from sub-$0.06/kWh sites in Kazakhstan toward Ethiopia, Paraguay, and stranded-gas operations in West Texas and Alberta. The 2028 halving will repeat the pattern, with sub-$0.04/kWh operations and behind-the-meter setups absorbing share at the expense of grid-tied $0.05-0.07/kWh operators. The investible angle is concentrated in vertically-integrated operators that own power, not in pure-play hash-rate aggregators.
What changes structurally this cycle
- ETF options. Listed options on IBIT and FBTC give institutions a regulated way to express convexity views around the halving for the first time. Implied volatility term structure across the April 2028 expiry will be the cleanest tradable read on market expectations.
- Sovereign holding. US strategic reserve debate, Bhutan’s DHI holdings (~13,000 BTC), El Salvador (~6,000 BTC) and several US states create a structural bid that did not exist in prior cycles.
- Lightning and L2 scaling. Off-chain fee absorption matters more as base-layer congestion drives fees into mining revenue.
- MiCA and Asian regulatory clarity. Spot ETF rollouts beyond the US in 2026-27 broaden the demand base.
- Public miner capital structure. Convertible debt issuance has shifted miner balance-sheet behaviour from forced sellers to opportunistic ones.
What to actually monitor
Three forward indicators carry the most information. First, hashprice itself, published daily by Luxor and Hashrate Index — if hashprice falls below the $0.035-$0.04 range pre-halving and stays there, miner capitulation in 2028 will be sharper than in 2024. Second, the cumulative net ETF flow versus daily new issuance: if ETFs absorb more than 100% of new supply on a trailing 30-day basis through Q1 2028 (the current run rate has averaged 70-180% in recent months), the supply shock is mechanical rather than narrative. Third, the futures curve at the CME — the 12-month basis between front-month and December 2028 contracts gives you the regulated market’s expression of the post-halving thesis. Our market hub tracks all three, and the events calendar flags the halving block in real time.
The “stock-to-flow” debate, killed and not replaced
For most of 2019-2022, the dominant model for halving-based price forecasting was PlanB’s stock-to-flow framework, which fit historical BTC price to the ratio of existing supply over new annual issuance. The model called for $100,000+ BTC by late 2021 and progressively higher targets through 2024. By mid-2022, with BTC trading at $20,000 against a model-implied $100,000, the framework was empirically broken — not because the math was wrong, but because it had only three data points and overfit them with two free parameters. The intellectually honest replacement is that no single-variable model survives contact with a maturing market. Realised demand, ETF flows, miner financing costs, and macro liquidity (measured against series like Federal Reserve total assets) all matter, and their relative weights shift over cycles. Anyone selling you a clean single-factor model for the 2028 halving is selling you a souvenir from the last cycle.
The miner equity trade, considered separately
Listed miners are not BTC proxies, despite being marketed that way. They are levered, capex-heavy operators with single-commodity revenue exposure, fleet-obsolescence risk, electricity-price exposure, and equity dilution baked into the business model — every public miner has issued shares to finance ASIC purchases at least once in the past two years. The realised beta of MARA, RIOT, CLSK, and CIFR to BTC over rolling 90-day windows has ranged from 1.4 to 3.8, with no stable equilibrium. Pre-halving, the cohort typically outperforms BTC as investors price in operational leverage to a higher coin price; post-halving, the cohort typically underperforms BTC as hashprice compression bites operating margins. The 2028 setup will repeat the 2024 pattern unless the public miner cohort has by then materially diversified into HPC/AI hosting (Core Scientific has, MARA partially has, others have not). The trade is not “long BTC via miner equity”; it is “long operational leverage to BTC at a known capex cycle.” Different question, different answer.
The honest position on the 2028 halving is that the supply-side math is fully known — block 1,050,000 will produce 1.5625 BTC and daily issuance will halve — and the demand-side math is almost entirely path-dependent. The cycle structure that produced 2013, 2017, and 2021 may persist, may mute, or may invert as the asset matures into something closer to a reserve commodity. The bear case is no longer “Bitcoin goes to zero”; it is “Bitcoin compounds at high single digits with declining volatility, like a small monetary metal.” The bull case is no longer “to the moon”; it is “the supply shock meets a structural demand bid and produces the steepest cycle yet.” Both are defensible. Neither requires you to predict the path between here and the block. The arithmetic does its work either way, and the calendar is the same for everyone.
