Fortitude Mining Readies IPO; Zcash Economics Outperform HPC Colocation

• Fortitude Mining, a Zcash-focused digital asset mining platform under Digital Currency Group (DCG), has announced plans to list on Nasdaq.
• The listing will occur through an all-stock merger with HeartSciences, with the proposed company operating under the Fortitude brand and trading as TUDE, pending Nasdaq approval.
• Fortitude, which commenced mining ZEC in 2019, reports an annualized run rate of 157,000 ZEC.
• Based on a ZEC price of approximately $400, this production rate implies a static annualized revenue of about $62 million.
• The recent rally in ZEC has significantly improved Equihash mining economics, making them competitive with, and in some instances exceeding, estimated High-Performance Computing (HPC) colocation revenue per megawatt.
• A Zcash-focused Z15 Pro miner generates an estimated $373 per MWh, compared to a conservative $223 per MWh for HPC colocation and $133 per MWh for a next-generation Bitcoin miner (S23 Pro).

Fortitude Mining, a Zcash-focused digital asset mining platform operating under Digital Currency Group (DCG), announced its intention to go public on Nasdaq. The company plans an all-stock merger with HeartSciences, with the combined entity expected to trade as TUDE under the Fortitude brand, pending Nasdaq approval. This development occurs amid significant shifts in the economic landscape for proof-of-work mining, particularly concerning non-Bitcoin assets.

The planned public listing positions Fortitude as a critical test case for investor interest in crypto-native compute businesses not primarily aligned with the burgeoning artificial intelligence (AI) sector. Fortitude began mining ZEC, the native token of the Zcash network, in 2019. It has since scaled its production to an annualized run rate of 157,000 ZEC. At a ZEC price of approximately $400, this production rate implies a static annualized revenue of about $62 million.

Compute Market Dynamics

The price appreciation of ZEC since late last year, alongside renewed network hashrate momentum, has re-energized Equihash mining economics. Revenue per unit of power now frequently compares favorably not only with other proof-of-work assets but also with estimated High-Performance Computing (HPC) colocation economics.

TheEnergyMag's recent analysis of compute market hierarchy, expressed as dollars per megawatt-hour, illustrates this shift. A Zcash-focused Z15 Pro miner is estimated to generate $373 per MWh. This surpasses a conservative $223 per MWh estimate for HPC colocation. For context, a next-generation Bitcoin miner, the S23 Pro, produces approximately $133 per MWh, while the S21 Pro yields about $84 per MWh. Other models, including the DG1+ and Kaspa-focused KS5 and KS3, generate around $65, $48, and $19 per MWh, respectively, under the same analytical assumptions.

This comparison highlights that the decision to allocate power is not always a straightforward choice between crypto mining and AI infrastructure. Rather, it is a competition for electricity based on compute revenue versus power cost. While HPC contracts offer attributes such as longer duration, lower volatility, and increased visibility, proof-of-work mining maintains optionality. When a digital asset's price rallies substantially faster than its network difficulty adjusts, mining revenue can temporarily exceed what infrastructure owners might earn from contracted HPC hosting. Zcash currently exemplifies this dynamic.
