Cipher Digital Sinks 12% on $850 Million Zero-Coupon Convertible Note Offering
Cipher Digital (CIFR) shares fell 12% after announcing an $850 million zero-coupon convertible note offering due 2032, with an option for $150 million more. The company plans to exchange part of its 1.75% 2030 notes for stock, adding to a 75% increase in diluted shares since 2021. Proceeds will partly fund capped calls to reduce dilution and support a $750 million equity investment in an AI lab project.
How this was made

The 30-second read
Why it matters
The immediate trading focus is dilution mechanics: the 2032 conversion price and capped-call cap are not yet set, while the 2030 swap can deliver stock sooner, contributing to today’s selling pressure.
Market read
A large, dilutive convertible issuance with unknown conversion price and capped-call cap is a direct catalyst for CIFR valuation and near-term trading volatility.
What to watch
The article notes a faster dilution from swapping part of 1.75% 2030 notes into stock and a large debt jump; traders should also weigh whether the Barber Lake lease economics and equity funding reduce longer-term credit risk.
Background
Cipher Digital filed to issue zero-interest convertible senior notes due 2032 and also plans to swap part of its 1.75% 2030 notes for stock, amid rising debt and contracted revenue tied to the Barber Lake AI-lab lease.
Ticker impact
Cipher Digital proposed $850M zero-interest convertible notes due 2032, plus a $150M option, and the terms set conversion dilution risk.
Shares likely face continued volatility and downside bias until conversion price and cap are set, because dilution mechanics drive holder selling and valuation.
The article attributes the 12% drop to the proposed convertible issuance and explains dilution timing (2030 swap hits faster, 2032 conversion depends on an as-yet-unknown conversion price).
Market effects
Highlights ongoing financing and dilution risk for AI-adjacent infrastructure developers using long-term contracted revenue plus equity raises.
Primarily US small-cap growth sentiment, with potential spillover to other highly levered, contract-backed issuers.
Limited beyond convertible-bond market pricing and risk appetite for zero-coupon convertibles.
Counterpoint
The notes are zero-coupon and capped-call structures may materially limit effective dilution versus the headline, especially if the capped-call cap is set favorably.
