Hashrate Index Roundup (September 21, 2026)

Hello world, happy Monday!

TLDR

A green bag for this week's update: Bitcoin up, hashrate down, difficulty down, fees up; hashprice is up.

Over the past week, miners collected a total of ~3,203 BTC in block rewards, equivalent to ~$249 million. Transaction fees constituted 0.59% of block rewards totalling 19 BTC, equivalent to ~$1.47 million.

Bitcoin

Bitcoin moved by 10.9% from ~$77,567 to a current price of ~$86,003. Year-to-date (YTD) performance stands at -1.6%.

Hashprice

USD hashprice moved +4.1% from $39.31 per PH/s/Day to a current $40.93 per PH/s/Day.

BTC hashprice moved -3.9% from 0.00049594 BTC per PH/s/Day to 0.00047652 BTC per PH/s/Day.

Based on fleetwide efficiency, bitcoin mining operations are currently earning the following SHA-256 compute revenues per watt-hour:

• Under 14 J/TH fleets — $136 per MWh
• 14-19 J/TH fleets — $99 per MWh
• 19-25 J/TH — $74 per MWh
• 25-38 J/TH — $51 per MWh

Hashrate & Difficulty

Network hashrate changed by -0.3%, with the 7-day simple moving average (SMA) moving from 949 EH/s to 946 EH/s. The 30-day SMA currently stands at 934 EH/s.

The latest difficulty adjustment took place on September 19, 2026, changing network difficulty by +4.16% to 132.76T.

Block times have averaged around 10m 11s over the past 24 hours.

We currently estimate* -1.80% for the upcoming adjustment, expected to occur on October 3, 2026.

*This estimate will change given that we are so early into a difficulty epoch. Early on, difficulty predictions are shaky because of short-term variance. As time (or blocks) pass, the noise fades and the signal sharpens.

At $40 per PH/s/Day, hashprice is at or below breakeven for many miners depending on operating cost and machine model type. Improve the hashrate and efficiency of your S19 and S21 series rigs by downloading LuxOS firmware today!

Transaction Fees

Over the past week, miners collected an average of 0.0191 BTC per block per day in transaction fees, +4% compared to the prior week's 0.0185 BTC.

Looking Forward

For this week's Hashrate Forward Market update, the forward market is pricing in an average hashprice of $38.96  or 0.00045 BTC over the next six months.
