MARA Holdings Falls 5%, Riot Platforms Sinks 4% as Rates Outweigh a 35,577 Bitcoin Treasury

The Decoupling From Bitcoin

Through Monday’s close, MARA Holdings stock was up 8% year to date, and Riot Platforms stock was up 58%. The iShares Bitcoin Trust ETF (NASDAQ:IBIT) was down 27% across that window. Miner equities have outrun spot Bitcoin exposure in 2026 because investors rerated them as data center developers rather than coin proxies (we pulled together seven of those non-chipmaker AI infrastructure suppliers in a free report here).

Contracted AI capacity, secured power, and the cost of capital now set valuations. A Bitcoin treasury sits as a balance sheet asset for MARA, while the multiple gets set by contracted AI capacity. MARA stock can hold against a 35,577 BTC treasury and still fall on a yield move.

Peers Follow the Move

Cipher Mining is the hardest hit and is building industrial-scale high performance computing data centers for hyperscale tenants. CIFR stock was up 25% year to date through Monday’s close.

Riot Platforms holds approximately 2 GW of available power capacity and has 241 MW of contracted critical IT capacity at its Rockdale campus, representing roughly $9.8 billion in long-term contracted revenue. RIOT stock rose 58.17% year to date through Monday’s close.

HIVE Digital Technologies is giving back Monday’s gain that followed a five-year, $350 million GPU cloud services agreement through its BUZZ HPC subsidiary, per Monday’s coverage. HIVE stock was up 19% year to date through Monday’s close, and Cipher Mining also rose modestly on Monday before Tuesday’s reversal.

Notably, the iShares Bitcoin Trust ETF holds spot Bitcoin and was down 26.65% year to date. Its 2026 decline measured against MARA Holdings stock climbing 8.18% year to date through Monday’s close quantifies how far these equities have separated from the asset the companies mine.

Bull and Bear Cases

The bull case for MARA rests on scarce power and land, a 4.8 GW target portfolio, and a substantial Bitcoin treasury on the balance sheet. None of that changed because yields moved higher, and the strategic assets remain in place.

The bear case: the powered land pipeline still needs capital to build against, higher rates raise that cost, and MARA remains unprofitable. A Bitcoin treasury layers a second volatile exposure onto operating risk.

What to Watch

Given the low absolute share price and compounding volatility from both yields and Bitcoin, position sizing should stay modest for anyone with exposure across the miner complex. The trade is an infrastructure bet with a coin overlay, and both legs are moving at once.

Investors could look for signs that the 10-year yield clears its 52-week high of 4.747%, which would extend today’s pressure on rate-sensitive AI infrastructure names. Traders may want to keep an eye on whether MARA’s Texas site converts to contracted capacity in the second half.

Open questions for MARA Holdings include how the remaining buildout gets funded and whether contracted cash flows arrive fast enough to justify the current pipeline. The 35,577 Bitcoin treasury is a balance sheet cushion, and the near-term stock move is being decided by rates.
