Post-Halving Mining Economics Are Forcing New Revenue Models Into the Open

The economics of pure-play Bitcoin mining are not sustainable at current hashrate levels and current BTC prices. This is not a controversial claim at the miner operator level; it is the subject of nearly every internal strategy deck at the major U.S. operators. What is newer is the set of revenue models the industry is building to compensate, and the pace at which those models are being deployed.

The revenue categories beyond block rewards

Miners are, in 2026, building revenue from five categories:

• Block rewards (the traditional core)
• Transaction fees (volatile, increasingly material)
• HPC / AI colocation (the Marathon pivot story)
• Hash-backed lending and hash derivatives
• Block template auctions and priority-fee routing (MEV-adjacent)

The first two are the classical mining revenue. The third, as covered extensively in recent earnings coverage, is the most visible diversification story. The fourth and fifth are the newer and more structurally interesting developments.

Hash-backed lending

Luxor, Galaxy, and a handful of smaller players now offer hash-backed lending products — loans collateralized by future hashrate output rather than by ASIC hardware or by BTC holdings. The economics, for miners, are attractive: a hash-backed loan allows the miner to monetize the expected cash flows of its fleet without selling the underlying BTC as it is produced. The economics, for lenders, are workable but require sophisticated modeling of hashrate and price covariance.

"The hash-backed lending market was about $180 million in aggregate outstanding balance at the start of the year. It's closer to $650 million today, and every significant miner is either a borrower or a customer of a borrower." — Ethan Vera, Luxor

Block template auctions

The more controversial development is the emergence of block template auctions. In this model, a block-producing miner does not construct its own block template; it receives template proposals from external actors (builders) who pay the miner for the right to have their template included. The mechanism borrows heavily from the MEV-boost architecture that has been operational on Ethereum for several years.

The Bitcoin version is more constrained than the Ethereum one, because Bitcoin's scripting language does not support the same range of MEV extraction techniques. But the basic pattern — a market for block content among specialists, with miners earning a share of the extraction — is emerging anyway. Early experiments by several pools have reportedly added 2-4% to per-block revenue, which is meaningful at current margins.

The community response

The Bitcoin developer community has generally been skeptical of MEV-adjacent revenue models, on the basis that they introduce complexity and potentially centralization into a protocol whose design aims to minimize both. The counter-argument, articulated most clearly by the pool operators running the experiments, is that the revenue models are emerging regardless of the community's preferences, and that structured versions are preferable to unstructured ones.

• Pro arguments: additional miner revenue at thin margins, better price discovery for block space, extension of Bitcoin's usable economic surface
• Con arguments: centralization risk, protocol complexity, potential for extraction at user expense

Where this ends

The likely long-run equilibrium is some version of what has happened on Ethereum: a structured builder/proposer separation, with revenue shared between the parties, and with specific carve-outs for transactions that should not be subject to extraction. Whether Bitcoin gets to this equilibrium through formal protocol changes or through off-chain coordination among pool operators is not yet settled. The market pressure is strong enough that the equilibrium will emerge one way or another. The question is how clean the path to it is.
