Bitcoin Miner Marathon Digital to Buy New Mining Sites for $179M as Reward Halving Nears
Marathon said the acquisitions will reduce the cost per coin mined by around 30%.

Bitcoin miner Marathon Digital (MARA) is digging into its hoard of cash to buy two sites from subsidiaries of lending firm Generate Capital in an acquisition that will reduce its mining costs before the reward for securing the blockchain is slashed by 50% next year.
The $178.6 million acquisition, which will add 390 megawatts of capacity, will be paid in cash, the company said Tuesday. Marathon said it expects the purchase to reduce the cost per coin mined by around 30%.
Bitcoin's [BTC] halving, expected in April 2024, is leading mining companies to reassess their operations to ensure they are prepared for the drop in rewards. One such way is by acquiring smaller firms to bring economies of scale to their activities. Earlier this month, Marathon said it had more than $800 million of cash and bitcoin to "capitalize on strategic opportunities, including industry consolidation" ahead of the halving.
Across the two sites, around 21% is vacant and available for expansion, 63% is occupied by bitcoin mining tenants and 16% is already occupied by Marathon.
Generate Capital acquired stakes in two mining sites from bankrupt miner Compute North for $5 million in November last year.
Marathon's Nasdaq-listed shares have gained about 13% to $22.44, one of the better performers among its mining peers. The bitcoin price has risen about 3.2% in the last 24 hours.

Specialized AI detects 92% of real-world DeFi exploits

New research claims specialized AI dramatically outperforms general-purpose models at detecting exploited DeFi vulnerabilities.
What to know:
- A purpose-built AI security agent detected vulnerabilities in 92% of 90 exploited DeFi contracts ($96.8 million in exploit value), compared with 34% and $7.5 million for a baseline GPT-5.1-based coding agent running on the same underlying model.
- The gap came from domain-specific security methodology layered on top of the model, not differences in core AI capability, according to the report.
- The findings come as prior research from Anthropic and OpenAI shows AI agents can execute end-to-end smart contract exploits at low cost, accelerating concerns that offensive AI capabilities are scaling faster than defensive adoption.
