Two tokenomics changes reshaped how Helium hotspot earnings should be calculated, and any honest estimate has to reflect both.
HIP-138: back to a single token
Under HIP-138, the separate IOT and MOBILE subnetwork tokens stopped being emitted, and rewards consolidated into a single HNT token. For operators, this simplifies the mental model — you earn HNT directly for providing coverage — but it also means earnings track HNT's price and emission schedule, not a separate sub-token economy.
The 2025 halving
Helium emissions follow a halving schedule. The 2025 halving cut the HNT emission rate, which lowers the token flow to the whole network — including coverage rewards — unless usage-based demand offsets it. In practice, this pushed realistic hotspot baselines down versus pre-halving figures.
What it means for your estimate
If you're sizing a Helium hotspot, the takeaway is: model post-HIP-138 single-token HNT at the post-halving emission rate, then convert at the live HNT price. That's exactly how our Helium calculator is built — see the assumptions and sources in the Helium methodology.
Coverage rewards also depend on density (proof-of-coverage), data transfer and your hardware — not just emissions. We show ranges, not a single promised number.
