Cipher (renamed Cipher Digital Inc. on 20 February 2026) holds signed, credit-supported leases but has not yet shown that they amount to a durable advantage. Its 2025 Form 10-K (filed 2026-02-24) says "Through the end of 2025, our revenue has been derived from mining bitcoin". Its Q2 2026 business update (2026-08-04, Exhibit 99.1, https://www.sec.gov/Archives/edgar/data/1819989/000181998926000038/q226_earningsxprxdraftxvf.htm) reported "Q2 2026 Revenue of $25 million", and its first HPC rent began only in August 2026 at Black Pearl. The 10-K's own risk factors describe a contested market. They say "There has been an increasing number of businesses constructing HPC data centers, which has resulted in increasing competition and pricing pressure that may cause us to reduce our pricing in order to remain competitive", that "our data centers are single-tenant properties", and that lessees "will have the right to terminate the lease if there are significant delays in the completion of construction". At Barber Lake, where the 10-K targeted Phase I delivery "by September 30, 2026", a September 2026 amendment, made "In connection with change orders and the continued evolution of tenant requirements", moved data-hall deliveries to the fourth quarter of 2026 through the first quarter of 2027. Under it, Cipher "will bear the first $359.3 million of costs in excess of the initial budgeted amount" (2026-09-25). There is real counter-evidence: a 15-year Amazon lease, a Google-backstopped Fluidstack lease whose contracted life a "leading AI lab" extended to 20 years, and a third lease with an investment-grade hyperscale tenant. Until that capacity is delivered and paying rent, though, a moat is not shown, so the band is none.

The FY2026 10-K (filed 2026-08-27) shows IREN holds an input the industry competes on: it names 'access to secured and energized power' first among what it believes are the principal competitive factors in its industry, and reports 'executed grid connection agreements, letters of agreement or equivalents representing approximately 5GW of total power capacity' in the United States, Canada, Spain and Australia as of June 30, 2026. It does not claim an advantage over rivals in that input. It says 'Certain competitors may have access to more competitively priced power, a greater access to power and a better capacity to timely secure grid connections,' and 'Many of our competitors have greater financial, technical or commercial resources, longer cloud operating histories or larger customer bases, compared to us.' Operating AI Cloud Services capacity was approximately 40MW at June 30, 2026, and the stored XBRL fundamentals from this 10-K show an FY2026 operating loss of about $1,046.7M on revenue of about $707.0M, so no durable advantage is yet demonstrated.

narrow

Phison's edge is real but contestable. Its 2025 annual report says 'The core technology of Flash products is the controllers and the integration of their firmware and software'. It reports about 2,000 NAND-related patents and says 'our controllers are sold to Tier-1 NAND vendors such as Kioxia, Kingston, and Micron'. It spent 18.96% of 2025 revenue on R&D. Gross margin was 32.41% in 2024 and 34.21% in 2025, before the 2026 NAND upswing. The same report concedes that 'Most of the business opportunities and core technology are in the hands of big NAND Flash suppliers' and that 'The controller suppliers in Taiwan are holding fewer and fewer advantages'. Tom's Hardware (2025-05-29) says Phison's E26 had dominated high-end PCIe 5.0 client SSDs 'for several years'. It adds that 'this monopoly is about to end' because over a dozen SSD makers showed Silicon Motion SM2508 drives.

Moat type none

No moat source is demonstrated yet. Switching costs are the most likely candidate, since the leases are long (15 years at Black Pearl; Barber Lake now a 20-year contracted life) and each site has a single tenant. But the 10-K says tenant guarantees "will only be effective after rent commencement under such leases and are subject to certain limitations", and by August 2026 rent had begun at only one site. The advantages the 10-K claims are the company's own. It speaks of "industry-leading expertise in originating and securing industrial-scale, greenfield data center sites" and of securing West Texas land "on more favorable terms than in more established data center markets". The same document says "there is significant competition for power capacity and energized facilities". Intellectual property is modest: "four granted United States patents and one issued patent in Taiwan". With 66 full-time employees, Cipher has no scale advantage over the competitors it names: CoreWeave, Digital Realty, Equinix, Vantage Data Centers and Aligned Data Centers.

none

The FY2026 10-K's asserted advantage is control from owning its data centers, 'including the associated land, grid connections and substations', which it believes allows it 'to benefit from more sustainable cash flows and operational flexibility relative to operators that rely upon third-party colocation services or short-term land leases'. Its only scale language is a belief that its 'procurement scale, deployment experience and direct control over the data center layer' lets it bring new compute into service 'rapidly and at scale', a deployment-speed claim, and it 'generally target[s]' regions with 'low-cost and attractive renewable energy sources', a siting target rather than a demonstrated cost position. It does not claim a cost or scale lead: it says 'Many of our competitors are larger, have longer operating histories and significantly greater resources than we do' and that certain competitors 'may have access to more competitively priced power, a greater access to power and a better capacity to timely secure grid connections.' There is no network effect or lock-in either, since existing contracts have 'terms ranging from month to month up to five years'. No enumerated moat source is grounded.

intangibles ip

The advantage Phison names is controller and firmware know-how backed by patents, not scale or lock-in. The annual report says 'Firmware technology is the key' to supporting all major flash specifications with high compatibility. It says the company has worked on NAND controllers for over 20 years and 'obtained about 2,000 patents related to NAND Flash technologies'. Its 2Q26 earnings deck counts '2100+' global patents, including pending ones. The IP is not exclusive. The report says many NAND peripheral specifications have patent protection, so 'how to obtain enough NAND Flash memory material and how to obtain relevant patent authorization are critical issues to us'. It calls 'the close relationship with the international big NAND Flash suppliers' the 'most critical factor' for staying in the supply chain.

Leadership fast follower

No independent share or rank was found. The 10-K names CoreWeave, Digital Realty, Equinix, Vantage Data Centers and Aligned Data Centers as competitors, along with miners that have "signed leases with hyperscalers and HPC tenants": Hut 8, IREN, TeraWulf, Core Scientific and Applied Digital. Cipher has signed hyperscale-grade tenants (Amazon; Fluidstack with a Google backstop; a third investment-grade hyperscaler) but delivered its first HPC capacity only in August 2026 (Q2 2026 update). That makes it a fast follower. Its self-description as "a leading developer, owner, and operator of industrial-scale data centers" is the company's own claim and is not counted.

behind

The 10-K lists IREN's competitors as hyperscalers (Amazon Web Services, Google Cloud, Microsoft Azure, Oracle Cloud) and specialized AI Cloud Services providers (CoreWeave, Nebius, Crusoe, Lambda, Nscale, SpaceX and others). It says IREN began providing AI Cloud Services in 2024 and cites its 'shorter operating history in AI Cloud Services relative to some competitors', and states 'Some of our competitors have longer operating histories, larger customer bases, more comprehensive IP portfolios and patent protections, more design wins, and greater financial, sales, marketing and distribution resources than we do.' Operating AI Cloud Services capacity was approximately 40MW at June 30, 2026. The filing describes a smaller, later entrant that trails some competitors on operating history, customer base and resources, with its progress so far resting on two anchor contracts (a ~$9.7B five-year Microsoft agreement and a ~$3.4B five-year NVIDIA contract) rather than any claimed category position.

co leader

Third-party coverage frames merchant controllers as a contest between Phison and Silicon Motion. Tom's Hardware (2025-05-29) says the high-end PCIe 5.0 client SSD market had been 'dominated' by Phison's E26 'for several years', until over a dozen SSD makers showed SM2508-based drives. Its 2026-06-16 interview notes that 'both Silicon Motion and its rival Phison posted record Q1 results'. In that interview, Silicon Motion says 'most module makers use our controllers'. A Morgan Stanley note reported by TechNews (2025-11-10) expects Phison's controller share to keep growing. No tracker publishes a controller ranking, and Phison's annual report gives no share figure. In enterprise SSDs it is outside TrendForce's 2Q26 top five. The band is therefore held at co-leader, not leader.

Pricing power weak

The 10-K says competition "has resulted in increasing competition and pricing pressure that may cause us to reduce our pricing in order to remain competitive". It adds that if customers cut usage "we may be compelled to lower our prices or risk losing a significant customer". At Barber Lake, Cipher agreed to absorb "the first $359.3 million of costs in excess of the initial budgeted amount", with the tenant reimbursing "50% of any such costs above that amount" (2026-09-25, Exhibit 99.1, https://www.sec.gov/Archives/edgar/data/1819989/000181998926000043/barberlakeleaseamendmentpr.htm). Its one input-cost edge is specific to mining: Odessa's power costs about 2.8 c/kWh under the Luminant contract, available "until at least July 2027". A landlord that concedes cost overruns to its tenants has weak pricing power.

weak

The 10-K's risk factors state 'Our competitors' products, services and technologies may be cheaper or provide better functionality or features than ours, which has resulted and may in the future result in lower-than-expected selling prices or demand for our products.' They also say long-term contract pricing 'is generally fixed or agreed at the time of contracting', so if market pricing for comparable capacity rises during a contract's term 'we will not benefit from those increases with respect to capacity already committed under our existing long-term contracts', and that if customers suffer a downturn or discontinue its services it 'may be compelled to offer more flexible terms, lower our prices or risk losing a significant customer.' The stored XBRL fundamentals from this 10-K show FY2026 revenue of about $707.0M against an operating loss of about $1,046.7M, so there is no margin record yet that evidences pricing power.

moderate

Phison's gross margin held steady before the 2026 upswing: 32.41% in 2024 and 34.21% in 2025, per the annual report. The report ties 2025's pricing to mix: a higher share of lower-priced embedded modules cut both the average unit selling price and the average unit cost. But module products, 72.41% of 2025 revenue, are built from NAND bought from suppliers. The report lists 'Flash Memory in Control of Big International Suppliers' among its disadvantages. Its 2Q26 gross margin of 65.3%, against 29.1% a year earlier, tracks the NAND upswing. TrendForce (2026-03-02) reports that Phison was 'Following the lead of major NAND players like Sandisk' when it required prepayment or shorter payment cycles.

Summary

Cipher built bitcoin mining data centres in Texas and is now developing single-tenant AI and HPC campuses for lease to hyperscalers. Its 10-K reports a portfolio of "4.2 gigawatts ("GW") of capacity across 10 sites". It lists a 15-year Amazon Web Services lease for about 300 MW of turnkey capacity at Black Pearl and a Fluidstack lease at Barber Lake (300 MW gross) under which Google "has agreed to backstop certain obligations of Fluidstack". It describes bitcoin mining at Odessa on a Luminant power contract at about 2.8 c/kWh. In 2026 it signed a third campus lease "with an investment-grade Hyperscale tenant" (Q1 2026 update, 2026-05-05), delivered first Black Pearl capacity in August "two months ahead of the original schedule" with rent commenced, and fully funded its Stingray development with a bond (Q2 2026 update). On 2026-09-25 it said Barber Lake's contracted life was extended from 10 to 20 years, taking contracted revenue at the site "from $3.8 billion to over $9 billion". The 10-K says Odessa was "the first bitcoin mining data center awarded the Management and Operations, or M&O, Stamp of Approval award from the Uptime Institute", which is independent recognition of how the company operates. Against this, the latest quarter's revenue was still bitcoin mining and fell to $25 million. The 10-K describes growing "competition and pricing pressure", single-tenant concentration, and termination rights for construction delays. The Barber Lake schedule was reset, and Cipher absorbs the first $359.3 million of cost overruns. Cipher's contracted pipeline is substantial, but a competitive advantage is not yet demonstrated, so it is rated as having no moat. That could change to narrow once its leased campuses are delivered and paying rent.

Per its FY2026 10-K, IREN is a vertically integrated AI Cloud Services platform that owns the data center, compute and software layers, underpinned by executed grid connection agreements, letters of agreement or equivalents representing ~5GW and a further multi-GW development pipeline. Its commercial record is concentrated: a five-year Microsoft agreement (~$9.7B total contract value, Horizon 1 delivered and accepted in August 2026, Horizons 2-4 targeted for delivery in phases in calendar Q4 2026) and a five-year ~$3.4B NVIDIA cloud contract together make up a substantial majority of contracted revenue. It holds NVIDIA Preferred Partner and Exemplar Cloud status (HGX B300 and GB300 NVL72) and a strategic partnership intended to support the deployment over time of up to 5GW of NVIDIA DSX-aligned infrastructure, which the filing cites among arrangements that are non-binding or subject to conditions, with no assurance as to the extent of deployments. Against that, the filing names hyperscaler and specialized competitors (AWS, Google Cloud, Azure, Oracle, CoreWeave, Nebius, Crusoe, Lambda, Nscale, SpaceX), many of which it says have greater resources, customers that can use or develop their own solutions, and possible delays to Texas energization from changes to ERCOT's Batch Zero procedures, so the power position is not a demonstrated advantage over rivals and its value depends on execution.

Phison designs NAND flash controllers, and most of its revenue comes from selling the storage built on them. In 2025, flash memory module products were 72.41% of its NT$72.664 billion revenue and controllers 19.26%. Its 2Q26 deck splits revenue into AI-ecosystem modules (enterprise SSDs, aiDAPTIV, boot drives and others) at 38%, embedded ODM modules at 33%, industrial modules at 16%, controllers at 6% and retail modules at 5%. Its controllers cover PCIe SSDs, eMMC/UFS, USB drives and SD cards. The annual report names Silicon Motion, ASolid and JMicron as the other major controller suppliers. Phison says its share of SSD controllers exceeds 20% and its share of automotive-grade controllers exceeds 40%. But its own annual report gives market share as 'Not applicable because there is no clear statistical data', and no independent tracker confirms either figure. Phison depends on the NAND makers for supply. Kioxia, a strategic partner since 2002, supplied 28.33% of 2025 purchases. The 2026 NAND shortage lifted 2Q26 revenue to NT$67.888 billion and gross margin to 65.3%, from 29.1% a year earlier. In February 2026 Phison followed its NAND suppliers in asking customers for prepayment or shorter payment cycles. Its growth bet is enterprise SSDs under the Pascari brand. There, TrendForce's 2Q26 top five brands are all NAND manufacturers.

Chain position

Cipher develops single-tenant, powered data-centre campuses for hyperscale and AI tenants: Amazon at Black Pearl, Fluidstack (backstopped by Google) at Barber Lake, and an unnamed investment-grade hyperscaler at a third campus. Meanwhile it winds down bitcoin mining.

Downstream AI-cloud operator: owns grid-connected data centers and deploys NVIDIA/AMD GPU systems it rents to hyperscalers, frontier labs, AI developers and enterprises (anchor customers Microsoft and NVIDIA).

Merchant NAND controller designer and storage-module supplier, sitting between the NAND makers and SSD, PC, smartphone, industrial and data-center customers. Kioxia supplied 28.33% of 2025 purchases, and no customer exceeded 10% of sales in 2024 or 2025.
