Bitcoin mining stocks are back in the spotlight as crypto prices rebound — and Terawulf stock (NASDAQ: WULF) is drawing attention thanks to its clean-energy strategy. Unlike many rivals, Terawulf relies on nuclear and hydro power, reducing both costs and carbon emissions.
But is Terawulf stock a solid buy in 2025? Let’s break down the business model, financials, and risks — in plain language that works for beginners, but with enough depth for advanced investors.
Company Snapshot (Investor Quick Facts)
- Ticker: WULF
- Industry: Cryptocurrency / Bitcoin Mining
- Founded: 2021
- Headquarters: Easton, Maryland, USA
- Market Cap: ~USD 3.5B (as of August 2025)
- Dividend Yield: None
- Facilities: Lake Mariner (NY, hydropower)
What They Do / Overview
Terawulf is a Bitcoin mining company.
- In simple terms: they run giant computer farms that solve math problems to validate Bitcoin transactions.
- The reward is new Bitcoins, which can be sold for revenue.
What sets Terawulf apart is energy sourcing:
- 91% of its power comes from nuclear, hydro, and other renewables (vs. many miners still burning fossil fuels).
- This not only lowers emissions but also stabilizes energy costs, which are the biggest expense in mining.
Think of Terawulf as a Bitcoin factory powered by clean energy instead of coal or gas.
Recent Performance & Key Metrics
For investors who like numbers, here’s how Terawulf is doing:
- Hash Rate (mining power): ~12.8 EH/s (exahashes per second) in mid-2025, aiming for 15 EH/s by year-end. Hash rate = mining horsepower. The higher it is, the more Bitcoin you can mine.
- Revenue: Q2 2025 revenue came in around $47.6M, up 60% YoY, thanks to Bitcoin’s recovery and higher mining capacity.
- EBITDA (profit before costs like debt/interest): Positive $14.5M in Q2 — a major improvement from prior quarters. This means they’re not fully profitable yet, but they’re closing the gap.
- Debt: ~$500M in liabilities, mostly from convertible senior notes. For a small-cap, this level of debt is significant and worth watching if Bitcoin prices fall.
- Cash on hand: ~$90M — gives them enough runway but not unlimited.
For context: Rivals like Marathon Digital (MARA) run at ~25 EH/s, so Terawulf is smaller but scaling fast.
Future Outlook
Looking forward:
- Bitcoin Halving (2028): The next block reward cut will reduce miner earnings per Bitcoin. Efficiency and cheap energy will be critical — and Terawulf has an edge here.
- Expansion Plans: Terawulf plans to grow capacity beyond 15 EH/s in 2026, mainly at its hydro powered Lake Mariner site.
- ESG Investing: With more funds screening for environmental impact, Terawulf’s clean-energy narrative could attract institutional capital.
In short: the company’s future depends heavily on Bitcoin prices, but its clean-energy model may give it staying power compared to dirtier miners.
Pros for Investors
✅ Exposure to the fast-growing Bitcoin mining industry
✅ Unique clean-energy model (91% nuclear/hydro)
✅ Growing hash rate with room to scale
✅ ESG appeal could attract institutional money
Risks
⚠️ Highly dependent on Bitcoin price swings
⚠️ Still not consistently profitable
⚠️ Small-cap = high volatility & dilution risk
⚠️ Debt levels need monitoring if cash flow stays weak
⚠️ Regulatory risks around crypto and energy usage

Conclusion
Terawulf stock is one of the few crypto mining plays pushing a clean-energy narrative. Its hash rate growth and sustainability angle give it long-term potential — but profitability and Bitcoin’s price remain the biggest wild cards.
At Invest Education we think that Bitcoin has a bright future for holding value and it can be equal to gold in the long term. Mining Bitcoin will be relevant at least for the next 10-30 years and the last mined coin will be around the year 2140, so Terawulf has plenty of time to continue their current model and to change it when the time comes. Betting on clean resources is also a good thing so we like the company and it is a good option for the Bitcoin enthusiast investor.
