Bitcoin has slipped below the 100,000-block mark to its next halving, putting the fifth reward cut on track for around mid-2028 at block 1,050,000 and setting up the first full halving cycle dominated by spot ETFs.
Summary
- Roughly 100,000 blocks remain until the next Bitcoin halving at block 1,050,000, expected in mid-2028
- Block rewards will fall from 3.125 BTC to 1.5625 BTC, further tightening new supply
- Analysts say spot ETF inflows could matter more than the halving itself for price dynamics this cycle
According to halving trackers like CoinGecko and IG, the next Bitcoin (BTC) halving is projected to occur when the blockchain hits block 1,050,000, cutting the block subsidy from 3.125 BTC to 1.5625 BTC and halving annualized issuance once again. With the network now past the 950,000-block area, data providers estimate roughly 100,000 blocks—or just over 700 days at current block times—remain until the event, implying an estimated date in April–May 2028. That milestone will mark the midpoint of the 2024–2028 cycle, the first in which spot Bitcoin exchange-traded funds (ETFs) play a central role in absorbing new supply.
Halving math versus ETF demand
Historically, halvings have driven Bitcoin’s stock-to-flow ratio higher by cutting the pace of new coin creation, reducing structural sell pressure from miners, and—at least in earlier cycles—setting the stage for 12–18 month bull runs as supply shocks met rising demand. After the April 2024 halving, the block reward dropped from 6.25 BTC to 3.125 BTC, pushing Bitcoin’s annualized inflation rate below that of gold; the 2028 halving will cut new issuance again to 1.5625 BTC per block. But the context is radically different now that U.S. spot Bitcoin ETFs hold well over $100 billion in assets and have become a primary conduit for institutional and retail flows.
As research cited by Investing.com notes, spot Bitcoin ETFs have attracted hundreds of millions of dollars in net inflows on strong days—$167 million in a single session and $521 million across a recent week—while global investment products tied to Bitcoin have logged billions in cumulative net demand. Earlier analysis from IG and others highlights that coins are increasingly locked in long-term wallets, corporate treasuries and ETFs, leaving exchange reserves at multi-year lows and thinning the actively traded supply. In that regime, some analysts argue the classic four-year “halving cycle” is effectively dead, replaced by an ETF liquidity cycle where large secondary market flows can overwhelm the marginal impact of issuance cuts, a view that’s circulated widely in CoinMarketCap’s halving-cycle commentary.
ETF flows already changed the last halving
The 2024 halving offered an early look at how ETFs might blunt traditional patterns. Unchained reported that spot ETF inflows began to wobble ahead of the event, with several days of modest net outflows totaling about $165 million, but the products still amassed over $54 billion in assets and roughly $12.5 billion in net inflows within months of launch. Even as Bitcoin sold off sharply from its 2025 peak, IG and other analysts noted that ETF redemptions were relatively muted compared with past cycle blow-offs, suggesting a stickier investor base than the leveraged speculators who dominated previous runs.
Looking ahead to the fifth halving in 2028, the key question is not just how much new supply is removed, but who controls the float: miners facing another 50% revenue cut, long-term holders, or ETF vehicles that must meet daily creations and redemptions. If spot ETFs continue to accumulate coins faster than miners can sell them into the market, the classic narrative of a predictable, programmatic supply shock may give way to something more complex—an ETF-driven liquidity regime where macro conditions, allocation decisions and regulatory shifts matter at least as much as the countdown to the next 100,000 blocks.
