Welcome back to another weekly mining roundup. For the week ending September 28, 2026, the macroeconomic and on-chain landscape for Bitcoin miners presented a mixed bag of incremental gains and headwinds. While spot Bitcoin prices posted modest weekly gains and transaction fees ticked upward, mining profitability experienced a slight contraction. Network hashrate continued its upward trajectory toward new highs, but the overall hashprice slipped as miners faced flat difficulty levels and tighter margins.
Bitcoin Price Action and Market Overview
Bitcoin’s spot price moved higher over the seven-day observation period, climbing roughly 2.5% from a starting point of approximately $81,412 to hover near $83,479 by the end of the week. Despite the positive weekly momentum, the asset’s year-to-date performance remains in negative territory, down around 4.5%.
Intraday volatility remained subdued, though the spot price dipped about 1.1% over a 24-hour window from a previous high of $84,413. CME futures contracts for upcoming months reflected steady market expectations, with September contracts trading at $83,830, October contracts at $84,285, and November contracts settling near $84,040. This forward-looking pricing indicates that derivatives markets anticipate relative stability in the near term, even as miners navigate shifting operational economics.
Hashprice Dynamics and Revenue Metrics
The financial returns of securing the Bitcoin network saw downward pressure over the week. The USD hashprice—a key metric representing the daily expected revenue of 1 terahash per second of hashing power—declined by 3.8%. Spot hashprice moved from $41.45 down to $39.87 per PH/s/Day. Over a broader one-month window, the 30-day average hashprice stood at $39.29, suggesting that current spot rates are lingering slightly above recent monthly baselines.
In BTC terms, hashprice remained virtually unchanged, moving marginally from 0.00047692 BTC to 0.00047670 BTC per PH/s/Day over the week. The 7-day average held steady at 0.00047686 BTC, while the 30-day average was recorded at 0.00049164 BTC.
Across the broader mining ecosystem, miners collected a cumulative total of approximately 3,112 BTC in block rewards over the past week, translating to roughly $262 million based on prevailing spot prices. With hashprices hovering near the $40 threshold, operations relying on older hardware models or higher electricity tariffs continue to operate near or below breakeven thresholds, underscoring the critical need for fleet efficiency upgrades and optimized firmware solutions.
Network Hashrate and Difficulty Adjustments
Network security and computational power pushed higher over the week. The 7-day simple moving average (SMA) for the Bitcoin network hashrate increased by 0.6%, moving from 946 EH/s to 952 EH/s, while the 30-day SMA stabilized at 948 EH/s.
The most recent network difficulty adjustment occurred on September 19, 2026, pushing network difficulty upward by 4.16% to 132.76T. Over the subsequent 24-hour monitoring period, block times averaged 10 minutes and 4 seconds. With roughly 68% of the current difficulty epoch completed—accounting for 1,363 out of 2,016 blocks—analysts estimate a minor downward adjustment of approximately -0.66% for the next epoch change, which is projected to take place on October 3, 2026.
Transaction Fees
Transaction fee generation provided a modest tailwind for miner revenues. Over the past week, miners collected an average of 0.0217 BTC per block per day in transaction fees, marking a 12% increase compared to the previous week’s average of 0.0194 BTC.
In total, transaction fees accounted for 0.70% of aggregate block rewards for the week, culminating in roughly 22 BTC, or about $1.83 million. Looking at broader moving averages, the 14-day average for transaction fees stood at 0.0206 BTC, while the 30-day average reached 0.0195 BTC, reflecting a steady, albeit gradual, expansion in on-chain activity compared to prior weeks.
Forward Markets and Outlook
Looking ahead, participants in the hashrate derivatives market are pricing in continued stability. The Luxor Hashrate Forward Market curve for the next six months anticipates an average hashprice of $38.34, or approximately 0.00046 BTC, running from September 2026 through February 2027. This forward curve suggests that market participants expect current economic conditions for miners to persist through the upcoming winter months.
Public Bitcoin Mining Equities
Publicly traded Bitcoin mining stocks experienced broad downward pressure alongside the contraction in hashprice. Over the five-day trading period leading up to the market close on September 28, nearly all major mining equities posted losses in line with broader digital asset market corrections.
Firms such as IREN, Riot Platforms, CleanSpark, Marathon Digital, and Core Scientific all registered notable single-digit to double-digit percentage pullbacks in their weekly share prices. Market capitalizations adjusted accordingly as institutional and retail sentiment reacted to the tighter margin environment currently facing enterprise-scale mining fleets.
