Cipher Mining AWS lease secures $5.5B deal to fund $2B Black Pearl data center

Cipher Mining’s pivot from bitcoin rigs to AI data centers just got a vote of confidence from one of the world’s largest cloud providers. On February 6, 2026, the company announced a 15-year lease with Amazon Web Services covering a 300 MW capacity at its Black Pearl campus in Wink, Texas, anchored by $5.5 billion in contracted revenue. Backed by AWS guarantees, the deal underpins a planned $2 billion senior secured notes offering aimed at completing the facility. For investors, it’s a litmus test of whether vertical-specific AI infrastructure can deliver the steady cash flows that hyperscalers demand.

Background

Cipher Mining started life as a pure-play bitcoin miner. Volatile crypto markets and rising electricity costs have pushed many operators to reconsider their assets. Instead of spinning down rigs, Cipher repurposed its power contracts and ERCOT interconnection rights to build a high-performance compute hub. The Black Pearl site, originally lined with bitcoin machines, is now designed to host GPU clusters and accelerators for AI training and inference. This move also echoes a broader industry trend of miners leveraging existing grid connections and power purchase agreements to secure hyperscale AI tenants, reducing the need for new greenfield assets. Late last year, Cipher tapped the debt markets with a $1.7 billion senior secured notes sale, setting the stage for a larger follow-on this February.

Deal Overview

The heart of the transaction is a 15-year commitment from AWS for the full 300 MW gross capacity—216 MW of critical IT load. The agreement locks in $5.5 billion of revenue over the lease term, with three five-year extension options. AWS is guaranteeing base rent and operating expenses, effectively de-risking a significant portion of the project’s fixed costs. On top of that, AWS covers cost overruns above a threshold of $9.5 million per megawatt and provides completion guarantees to ensure the facility hits design milestones. You’re not exposed to spot power prices or fluctuating crypto rewards—just a blue-chip tenant contract.

On top of the base 15-year term, Cipher and AWS hold three separate five-year extension options. If AWS exercises all options, the lease could stretch to 30 years, adding roughly $1.8 billion in potential revenue. That optionality further de-risks the asset and gives creditors and equity holders long-tail visibility into cash flows well beyond a typical data center cycle.

Financing Structure

To fund the build-out, Cipher launched a $2 billion senior secured notes offering at a 6.125% coupon. Demand was robust, with over $13 billion in orders—an order-to-cover ratio north of 6x. Proceeds will reimburse $232.5 million of prior investments and finance the remaining construction costs for the Black Pearl campus. The notes are secured by the Black Pearl assets and related contracts, giving bondholders a first lien on the facility and the AWS lease. Coverage ratios targeted above 1.5x on fixed rent payments compare favorably with typical data center financing benchmarks, where lenders often look for 1.3x as a minimum safety margin.

The offering is expected to settle in late March 2026, subject to customary closing conditions. Interest on the notes is payable semi-annually, aligning cash flows with revenue ramp. Because the notes are secured solely by the Black Pearl assets and contracts, they trade at a tightening spread over U.S. Treasuries compared to Cipher’s prior unsecured issuance.

Site and Construction

The Black Pearl campus occupies land near Wink, Texas, a town of just 919 residents in Winkler County’s Permian Basin. ERCOT has approved the site for interconnection, tapping into West Texas’ abundant but sometimes volatile power supply. The facility is designed for phased delivery—first rack-ready halls in September 2026, reaching full 300 MW capacity by February 2027. Construction includes multiple high-density compute halls, network hubs, and expansion pads for future growth. Rent commencement is set for October 1, 2026, aligning with AWS’s build-out schedule. Given AWS’s cost overrun and operating expense guarantees, Cipher’s equity holders are shielded from many of the common budget overruns.

Cipher is using a modular data hall approach, which lets AWS stagger GPU pod deployments without waiting for the entire campus to come online. This improves capital efficiency and reduces idle power consumption, delivering a leaner build-out tailored to actual hardware rollouts.

Investor Takeaways

Here’s what matters most. First, $5.5 billion of contracted revenue over 15 years translates to roughly $366 million in annualized run rate, assuming straight-line recognition. Second, the secured notes at 6.125% yield sit well below typical unsecured tech bond yields, reflecting the credit support from AWS. Third, Cipher’s equity trades at about a 28.2x price-to-sales multiple, pricing in a steep growth premium. If you’re bullish on dedicated AI compute and believe usage will ramp, this structure offers upside on the equity with downside protection in the debt.

For reference, traditional data center financiers look for debt service coverage above 1.3x. With an AWS tenant, Cipher aims for ratios closer to 1.5x, giving you a buffer against timing slips or minor cost overruns.

Compare this to standard data center leases, which often run five to ten years with rollover risk. A 15-year term plus extension rights locks in a multi-decade cycle of rental income, a feature that institutional investors prize for predictable returns.

Risks and Considerations

No deal is without hazards. Construction in a town of 919 residents could strain labor availability and drive up local costs. ERCOT power, while plentiful, can be volatile during extreme weather, so keep an eye on reserve margin reports in the summer and winter. Permian Basin’s history of oil-driven boom-and-bust cycles reminds us that regional infrastructure can lag demand.

The Permian Basin has faced scrutiny over water use and environmental permitting in recent years. While the site’s oil and gas legacy helped build the initial grid infrastructure, any change in state or federal resource regulations could delay expansion or add compliance costs. That’s a vector to watch, especially in a region known for tight labor markets and regulatory pushback when industry booms. AWS’s guarantees cover overruns above $9.5 million per MW but may not encompass every unforeseen expense or regulatory delay. Finally, at a near 28x price-to-sales multiple, you’re paying up for future growth. Any slowdown in AI spend or more competitive pricing from rivals like Google or Microsoft in Texas could compress margins and valuations.

Outlook

Cipher’s Black Pearl campus is a case study in repurposing crypto assets toward the AI infrastructure wave. If the AWS lease and financing close as planned, look for debt service coverage ratios above 1.5x once revenue ramps. Monitor interconnection utilization metrics, GPU deployment rates, and any new tenant additions beyond AWS. Over the next 12 to 18 months, the facility’s performance benchmarks will set a tone for how other bitcoin miners pivot assets.

Bottom Line

This transaction swaps bitcoin rewards’ highs and lows for the predictability of a hyperscaler tenant contract. For you as an investor, the secured notes give a solid yield with structural protections, and the equity holds potential upside if AI workloads continue their rapid growth. Just stay vigilant on construction execution, grid stability, and hyperscaler pricing trends. If you’re looking to play the AI infrastructure boom with a safety-first mindset, this deal deserves a spot on your watch list.
