On Friday — and over the past week — publicly traded bitcoin miners shrugged off the prior week’s funk and piled on a run of solid gains. Of the ten largest miners by market cap, all of them spent the last seven days comfortably swimming in green.
Bitcoin Miners Erupt in Weekly Rally
Across that same stretch, bitcoin logged an 8% climb against the U.S. dollar, and that momentum spilled straight into the mining sector. U.S. equities, not to be outdone, fired up their own blistering run, closing the week on the upside. The leaders of the miner pack came ready to scrap.
Take IREN Limited, for example — it stood out as the lone laggard with a –1.32% dip on the day, yet its 13.13% weekly climb and $13.55 billion market cap still keep it firmly in heavyweight territory. IREN’s latest Q1 FY26 report flashed strong year-over-year gains in revenue, helped along by fresh artificial intelligence (AI) cloud contracts, including a $9.7 billion deal with Microsoft.
Stats from bitcoinminingstock.io show Cipher Mining rolled into Friday with a confident 6.26% daily climb and a 43.81% seven-day lift, all backed by an $8.04 billion valuation. The weekly jump followed Cipher securing a 10-year high-performance computing (HPC) colocation agreement with Fluidstack.
Applied Digital kept pace with an 8.66% daily jump and 28.49% weekly climb, supported by a $7.58 billion market cap. Terawulf joined in, adding 4.51% today and 37.37% over the week, capped at $6.06 billion. Applied Digital just unveiled the completion of Phase II of its Polaris Forge 1 AI Factory Campus in North Dakota, while Terawulf spotlighted its third-quarter progress driven by bitcoin mining and HPC endeavors.
Riot Platforms pressed ahead with a 7.67% daily jump and a 26.90% weekly climb, landing just under $6 billion. Core Scientific added a 4.38% daily lift and a 14.66% weekly rise, supported by its $5.24 billion valuation. Riot recently delivered operational updates and Q3 results with record results, while Core Scientific disclosed the termination of its merger agreement with Coreweave.

Hut 8 booked a crisp 6.20% bump on Friday and a 31.04% weekly climb, backed by a $4.86 billion market cap. The company also unveiled plans to develop four new sites expected to exceed 1.5 GW of total capacity. MARA Holdings picked up 6.30% in 24 hours and 17.27% across the week, landing at $4.47 billion.
The company also reported a 92% year-over-year revenue jump to $252 million for Q3 2025. In ninth place came Cleanspark, posting a swift 12.26% jump on the day and a 55.19% weekly climb, pushing its valuation to $4.26 billion. Rounding out the top ten, Bitdeer logged a 5.84% daily lift and a 30.32% weekly climb, backed by a $2.8 billion market cap.
Cleanspark reported sweeping growth for fiscal year 2025, with revenues reaching $766.3 million — a 102% jump from the year prior. Meanwhile, Bitdeer recently announced the pricing of its $400 million convertible senior notes offering. The week wrapped with miners riding strong momentum, propelled by expanding AI contracts, fresh HPC builds, and a steady bitcoin lift that kept the sector energized.
Yet as these companies deepen their shift into AI and high-performance computing, an open question lingers: how will this evolving mix of priorities shape the bitcoin mining market in the long run? For now, the industry’s biggest players appear content to push forward, but the balance they strike in the months ahead may define the next chapter of the sector.
