Miners fund large construction ahead of revenue those facilities will produce, so borrowing costs and the discount rate on future contracted cash flows drive valuations. A yield move near the 52-week high hits the valuation multiple directly, while the coin balance remains unchanged on the balance sheet.
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).
