Key Takeaways
Why are Bitcoin miners outperforming BTC?
AI integration boosted Cipher and Iren by 300–500% YTD, reshaping mining into a data infrastructure business.
What does this mean for Bitcoin?
Stable miner revenue reduces sell pressure, setting BTC up for recovery toward $109K–$113K if momentum persists.
Bitcoin [BTC] faced a volatile October, diverging from its usual “Uptober” strength. The coin slipped below $107,000 mid-month, recording a 0.28% daily and 4.43% weekly drop.
However, the spotlight has shifted. Bitcoin miners are stealing the show, outperforming BTC with record-breaking gains driven by artificial intelligence (AI) integration and new revenue models.
Bitcoin mining stocks take the lead
2025 marked a historic year for BTC, with the coin largely trading above $100,000. Yet, the real winners were miners.
According to Bloomberg, Bitcoin miners outperformed traditional BTC miners by shifting to hybrid models that combine artificial intelligence and high-performance computing.

As such, the CoinShares Valkyrie Bitcoin Miners ETF surged over 150% year-to-date, outperforming Bitcoin itself.
Interestingly, investors’ perception of mining companies has shifted as they perceive them as tech infrastructure firms.
The key behind miner’s historic rally
Amid this, miner uptick, Cipher Mining Inc., and IREN LTD lead the way. In fact, Cipher Mining Inc. surged 304% in 2025.

Iren LTD had even made more gains, rising approximately 519% this year alone. The two firms have rallied significantly as they pivot from pure BTC mining to AI infrastructure, seeking consistent revenue.
Thus, instead of solely relying on BTC, these firms view that AI training could offer a safer and consistent source of revenue to boost their mining revenue.

Both companies have raised significant capital to fund this transition.
Cipher secured a $3 billion deal with Fluidstack, while Iren recently completed a $1 billion convertible notes offering.
These moves blur the line between AI computing and crypto mining, allowing miners to diversify earnings as the Bitcoin Halving reduced block rewards to 3.1 BTC.
This hybrid approach has changed how investors perceive risk. By tapping into AI-driven revenue streams, miners maintain steadier cash flows even when Bitcoin’s price falters.
Miner profitability remains strong
Significantly, amid a changing ecosystem, miners’ profitability, although moderate, has remained stable since the 22nd of June, when the Puell Multiple dropped below 1.
Since then, this metric has fluctuated between 1.3 and 1.2. At press time, Puell Multiple stood around 1.204, indicating a healthy miner profitability.

That stability has encouraged miners to hold their BTC rather than sell, reducing exchange inflows and alleviating potential selling pressure.
What this means for Bitcoin
Miners have outperformed Bitcoin this year as they pivot toward AI infrastructure, building steadier revenue streams beyond block rewards.
While BTC trails, this shift could serve as a strategic lifeline. Traditional investors often treat miner stocks as leveraged Bitcoin bets, meaning their rallies can signal early optimism for BTC’s next leg up.
When miner revenue stabilizes through alternate sources like AI computing, the pressure to liquidate BTC declines. This reduces selling risk and strengthens market supply dynamics.
If this pattern holds, Bitcoin may regain momentum and retest $109,590, potentially targeting the Short-Term Holder (STH) Realized Price near $113,200.
However, if miners remain cautious and selling pressure persists, BTC could consolidate between $105,000 and $112,000 for an extended period.
