Root, a well-known Bitcoin on-chain and cycle analyst, posted on X that halving progress has reached 61% on 22 Sep 2026, sharing a screenshot of the metric and the hashtag #Bitcoin. The update, cited by U.Today, marks the latest data point in the countdown to the next reward reduction.
Metric source and block count
According to the blockchain explorer OKLink, the network still needs 109,012 blocks before the subsidy cuts again. At the current block time of roughly 10 minutes, that translates to an estimated date of 13 Apr 2028. The 61% figure aligns with the linear progression model used by many cycle analysts, which assumes a steady block production rate.
Miner economics under a 1.5625 BTC reward
When the reward drops from 3.125 BTC to 1.5625 BTC, the revenue per hash will halve, assuming price and transaction fee levels remain constant. This compression disproportionately affects marginal miners whose electricity costs are near the breakeven point. Historical data from the 2020 halving showed a 12-month lag before the most inefficient miners exited the network, leading to a temporary hash-rate dip and a modest price correction. If a similar pattern repeats, liquidity could tighten as miners sell BTC to cover operating expenses, potentially amplifying price volatility.
Market reaction and ETF inflows
CoinMarketCap reported BTC trading at $86,099, up 0.86% in the prior 24 hours, with a recent high of $87,397 – the highest since January 2026. The price rally coincides with a surge in Bitcoin ETF inflows; BlackRock’s iShares Bitcoin Trust (IBIT) recorded $381 million in a single day, while ARK 21Shares and Fidelity’s FBTC each attracted over $200 million. Analysts suggest that institutional capital may be positioning ahead of the halving, anticipating a supply shock that could lift prices. The influx also raises regulatory exposure, as the SEC continues to scrutinize ETF structures and custody arrangements.
Operational risk for exchanges and custodians
A lower block reward reduces the net issuance of new BTC, tightening the supply side of the market. Exchanges that rely on mining revenue to fund internal liquidity pools may need to adjust their funding models. Custodians, especially those offering leveraged products, must reassess margin requirements; a sudden hash-rate decline could trigger network latency, affecting transaction finality and settlement times. These operational considerations are amplified by the growing share of Bitcoin in corporate treasuries, as highlighted in a recent report on Bitcoin treasury growth.
Regulatory angle
The upcoming halving will likely draw attention from regulators monitoring market stability. The SEC’s recent guidance on digital asset securities emphasizes the need for transparent pricing and robust risk controls. Should miner exits cause a sharp hash-rate drop, the resulting price swing could trigger heightened scrutiny of market manipulation claims. Moreover, the halving’s impact on transaction fees may affect the cost structure for on-chain services, prompting a review of fee-related disclosures under emerging crypto-specific regulations.
What to watch next
- Hash-rate trends: A sustained decline could signal miner capitulation; a stable or rising hash-rate would suggest confidence in profitability despite lower rewards.
- ETF flow patterns: Continued net inflows would reinforce the narrative of institutional accumulation ahead of the halving.
- Regulatory filings: Any new SEC statements on Bitcoin market integrity or ETF oversight should be tracked for potential policy shifts.
- Price-fee dynamics: As block rewards shrink, transaction fees are expected to play a larger role in miner revenue; monitoring fee per byte metrics will illuminate whether the network can sustain security.
Corroborating reports
The halving timeline aligns with analysis from Finbold, which also references OKLink’s block-count estimate. While the finbold piece focuses on a different asset, its methodology for projecting blockchain events mirrors Root’s approach, lending additional credibility to the 61% progress claim.
Broader market context
Bitcoin’s recent reclaim of long-term moving averages—its 365-day MA for the first time since March 2023—has historically preceded bull markets. The confluence of halving progress, institutional inflows, and a tightening supply curve creates a multi-factor environment where price action may become more sensitive to macro-economic shocks. Traders should therefore calibrate risk models to account for both on-chain fundamentals and external liquidity drivers.
Conclusion
Root’s 61% halving progress update provides a concrete data point for market participants assessing the next reward cut. The projected 13 Apr 2028 date, combined with miner economics, ETF inflows, and regulatory scrutiny, outlines a landscape where operational risk and liquidity considerations will be paramount. Stakeholders—from miners to custodians and institutional investors—must monitor hash-rate, fee structures, and policy developments to navigate the approaching halving with informed precision.
