Bitcoin Mining in 2025: Canaan Buybacks, MARA Optimizes BTC Reserves, Bitdeer Pivots to AI

The Bitcoin mining sector is entering a new strategic phase. The major players are no longer content with simply accumulating BTC — they are fundamentally reinventing their business models.

From share buybacks and active treasury management to a full pivot toward artificial intelligence, publicly listed miners are multiplying initiatives to attract institutional investors.

Here is a breakdown of the most significant moves reshaping the mining landscape in 2025.

Canaan and MARA: Two Opposing Approaches to Maximizing Shareholder Value

Canaan (CAN), one of the leading manufacturers of ASIC mining machines, has announced a share buyback program. The move is rare within the mining industry and sends a clear signal: management believes the stock is undervalued by the market. This type of operation mechanically reduces the number of shares in circulation, which improves earnings per share and supports the stock price.

Meanwhile, MARA Holdings (formerly Marathon Digital) is taking a different approach. The American miner is no longer simply holding Bitcoin on its balance sheet — it is actively managing it. MARA has notably turned to BTC lending to generate yield on its reserves, a strategy that closely resembles yield farming applied to the most liquid asset in the crypto market. With more than 40,000 BTC in its portfolio according to the latest disclosures, the financial stakes are considerable.

Both approaches illustrate a deeper trend: miners are increasingly seeking to behave like publicly listed financial companies rather than simple infrastructure operators. Pressure from equity markets is pushing them to justify their valuations beyond hashrate alone.

Bitdeer Accelerates Its AI Pivot: A Bet on Infrastructure Convergence

Bitdeer Technologies is going even further in its diversification strategy. The Singapore-based group, listed on the Nasdaq, is redirecting a significant portion of its data center capacity toward hosting compute workloads tied to artificial intelligence. The logic is compelling: the GPUs required to train AI models and the ASICs used for mining share the same fundamental requirements — power, cooling, and network connectivity.

This partial transition allows Bitdeer to tap into the explosive demand from tech companies seeking compute power, while simultaneously reducing its exposure to Bitcoin price volatility. Revenue generated from HPC (High Performance Computing) contracts offers far greater visibility than spot mining, which remains subject to the unpredictability of the halving and difficulty adjustments.

Other players such as Core Scientific and Hut 8 have followed a similar path, confirming that the AI pivot is no longer an exception but a structural trend. For investors, these companies are becoming pure plays on compute infrastructure, with Bitcoin mining as a complementary activity rather than a core one.

What These Shifts Reveal About the Future of Bitcoin Mining

The proliferation of these alternative strategies reflects an economic reality that is increasingly hard to ignore: following the April 2024 halving, miner revenues were cut in half in terms of BTC issued per block. In this context, maintaining profitability requires innovation well beyond the simple race for hashrate.

The best-capitalized miners now hold a structural advantage: their access to capital markets allows them to raise funds, buy back shares, or invest in new verticals without relying solely on the spot price of Bitcoin. This financialization of the sector is bringing the largest miners closer in profile to REITs or traditional infrastructure companies.

One central question remains: to what extent do these strategic pivots genuinely protect shareholders if Bitcoin were to experience a sharp correction? The correlation between the BTC price and miners’ stock market valuations remains high, and no diversification strategy yet appears capable of breaking it entirely.
