Cipher Mining Tumbles 18% on $1.1B Convertible Note Offering

Shares fall sharply as investors weigh the dilutive impact of the capital raise against the company's strategic expansion into AI infrastructure.

Shares of Cipher Mining (CIFR) plunged nearly 18% to $11.64 in heavy trading after the bitcoin mining company announced the pricing of an upsized $1.1 billion convertible senior note offering.

The offering places Cipher at a crossroads, making a bold, capital-intensive bet on a high-growth sector at the cost of near-term pain for its shareholders. The market is now watching to see if the long-term rewards of its AI ambitions can ultimately outweigh the immediate costs of dilution.
