Kaspa mining is the thinnest-margin business in this catalogue, and that makes it the most honest test of a hosting rate there is. The whole network earns $0.1736 per terahash per day. At that revenue level, a machine's efficiency and your electricity price do not merely affect the return — together they decide whether there is a return at all. Two of the three machines compared here are marginal at the network-average rate, and all three lose money on retail power.
THE SHORT ANSWER
What is the best Kaspa miner in 2026?
The Antminer KS7 at 40 TH/s and 77 J/TH. It is the only kHeavyHash machine in the catalogue with a clear margin, netting about $3.40 per day at $0.0480/kWh for a payback of 16.9 months. The IceRiver KS7 nets $1.18 and the KS5 Pro effectively nothing at $0.02. At the lowest industrial rate of $0.0364/kWh all three improve; on home power at $0.1200/kWh all three lose money. Efficiency is the whole game on Kaspa.
Start with the network. Kaspa runs 313,662 TH/s and emits roughly 2.00 million KAS per day at a block reward of about 2.31 KAS across ten blocks per second. At a KAS price of $0.02726 that is $0.1736 of gross revenue per terahash per day, and every figure in this article follows from that one number.

For scale, a terahash of Bitcoin currently earns $0.0379 per day — about 0.2 times less than a terahash of Kaspa. But Kaspa machines produce far fewer terahashes for far more power. An Antminer KS7 delivers 40 TH/s from 3,080 W, which is 77 J/TH against 9.5 J/TH for a current Bitcoin hydro machine. That is the trade Kaspa hardware makes, and it is why the electricity rate dominates.

The most efficient Kaspa machine available at 77 J/TH, and the only one with a clear margin at hosted rates.
On Bitcoin, a poor-efficiency machine on cheap power still makes money. On Kaspa it does not, because revenue per unit of work is far lower relative to power draw. Look at what efficiency does to these three.

Why the KS5 Pro is the cautionary tale
The KS5 Pro costs $1,199, which looks like an accessible entry into Kaspa mining. At 150 J/TH, electricity consumes 100% of its gross revenue at the network-average rate, leaving $0.02 a day. It is not a bad machine — it is a machine whose viability depends entirely on securing power at the very bottom of the market. At $0.0364/kWh it nets $0.89; on retail power it loses $5.43 every day.
The electricity rate table that settles it
How every number on this page was produced
Bitcoin figures use a hashprice of $37.85 per PH/s per day, derived from a BTC price of $76,768 and a network hashrate of 912.6 EH/s (difficulty 125.81T) on 2 September 2026. That is block subsidy only — transaction fees are excluded, so the revenue side is deliberately conservative. Zcash uses 1,440 ZEC per day to miners (80% of emission after the development fund) against a 24.48 GSol/s network. Scrypt credits both chains a merged-mining unit actually earns, Litecoin and Dogecoin. Electricity is charged at the OneMiners network average of $0.0480/kWh unless a table states otherwise, with no performance or management fee, because OneMiners charges none. Payback assumes difficulty and price hold still, which they never do — treat it as a ranking tool, not a forecast.

Net profit per day for every Kaspa machine in the catalogue, across four electricity rates. The hardware is identical across each row - only the power price changes.
Read that table row by row rather than column by column. The hardware is identical across each row; only the power price changes. The Antminer KS7 goes from $4.25 a day at the lowest industrial rate to a loss of $1.92 on retail power. That is a swing of $2,256 a year on one machine, driven entirely by where it is plugged in.

Kaspa carries the highest dilution exposure of any coin in this catalogue, and it is worth understanding before committing capital. Your revenue is a share of a fixed emission, so when the network grows your income falls proportionally.

One Antminer KS7 moves the Kaspa network roughly a hundred times more than a Bitcoin flagship moves Bitcoin. Small networks reprice fast in both directions.
An Antminer KS7 represents 128 parts per million of the entire Kaspa network. Only 7,842 more of them would halve every Kaspa miner's revenue — a single large deployment. Combine that with margins already consuming 51 per cent of gross revenue in power, and the case for sizing a Kaspa position modestly and pairing it with Bitcoin hashrate is difficult to argue against.
The verdict
BEST KASPA MINER
Antminer KS7 40 TH/s
77 J/TH, $3.40 a day at $0.0480/kWh and 16.9 months to payback. The only kHeavyHash machine with real margin.
CHEAPEST VIABLE ENTRY
IceRiver KS7 30 TH/s
$1,179 and $1.18 a day. Works, but 77% of revenue goes to power, so it needs a low rate to stay ahead.
ONLY ON THE CHEAPEST POWER
Antminer KS5 Pro 21 TH/s
$0.02 a day at the network average and $0.89 at the lowest industrial rate. The rate, not the machine, decides this one.
IF KASPA MARGINS WORRY YOU
Antminer S23 Hyd 3U
$31.22 a day at 1.27 ppm of its network, with power consuming only 29% of gross.
Kaspa is a bet on your power contract
At $0.1736 per terahash per day, the difference between $0.0364 and $0.1200 per kWh is the difference between a business and a loss. Compare the machines, then compare the rate you can actually secure.
On industrial power, marginally and only with the right machine. An Antminer KS7 nets about $3.40 a day at $0.0480/kWh and $4.25 at $0.0364/kWh. The KS5 Pro is close to break-even at the network average. On retail power at $0.1200/kWh every Kaspa machine loses money.
Which is better, the Antminer KS7 or the IceRiver KS7?
The Antminer, clearly. It delivers 40 TH/s at 77 J/TH against 30 TH/s at 117 J/TH for the IceRiver, and nets $3.40 a day against $1.18. The IceRiver is cheaper at $1,179 against $1,749, but the efficiency gap outweighs the price gap at any realistic rate.
How much does an Antminer KS7 earn per day?
About $3.40 net at $0.0480/kWh, from $6.95 gross less $3.55 of electricity. At the lowest industrial rate it nets $4.25; on home power it loses $1.92 a day.
Is the KS5 Pro worth buying?
Only if you have power at the very bottom of the market. At $1,199 the entry price is attractive, but at 150 J/TH electricity consumes 100% of its gross revenue at the network-average rate, leaving $0.02 a day. It is a rate decision more than a hardware decision.
Why are Kaspa margins so thin?
Because kHeavyHash hardware is far less efficient relative to its revenue than Bitcoin hardware. The best Kaspa machine runs 77 J/TH while a current Bitcoin hydro machine runs 9.5 J/TH. Kaspa pays more per terahash, but the machines spend far more energy producing each one.
Can I mine Kaspa with a Bitcoin miner?
No. Kaspa uses kHeavyHash and Bitcoin uses SHA-256; the silicon is not interchangeable. A KS-series machine cannot mine Bitcoin and an Antminer S23 cannot mine Kaspa.
How risky is Kaspa mining compared to Bitcoin?
Considerably higher on two counts. Margins are thinner, and dilution exposure is roughly 100 times greater — one Antminer KS7 is 128 parts per million of the Kaspa network against 1.27 ppm for a Bitcoin flagship. Only 7,842 more KS7 units would halve everyone's revenue.
Should I host a Kaspa miner or run it at home?
On these margins, hosting is close to a requirement. The same Antminer KS7 nets $4.25 a day at $0.0364/kWh and loses $1.92 at $0.1200/kWh — a swing of $2,256 a year. There is no version of home Kaspa mining that works at retail electricity prices.
