On July 28, Cipher Mining Inc. fell 5.27% in pre-market trading, trading at $20.50 per share, with turnover of approximately $1.13 million.

The decline was driven by a broader capital rotation out of chip and AI infrastructure stocks, which disproportionately impacted bitcoin miners with AI data center exposure. Market concerns centered on rising capital expenditure requirements and whether companies pivoting from mining to AI may need to raise incremental funding at higher costs to finance growth plans. Cipher Mining led the sector lower, with Hut 8 and Terawulf also falling 6% and 4% respectively. Pure bitcoin miners including Riot Platforms and CleanSpark also declined 5% and 4%.

Analysts noted that some investors are questioning whether credit demand for these projects is approaching its limits, and which developers can fund their pipelines without significant equity dilution or expensive debt. Cipher Digital recently priced an $810 million senior secured notes offering in June to finance its Stingray data center project, underscoring its capital-intensive transition toward HPC infrastructure.
