The Compute & Data — AI Cloud & Storage
Hyperscalers can't build fast enough alone. They rent.
@aleabitoreddit's edge is following the money trail. Hyperscalers don't just spend their $700B in capex internally — much of it flows outward to specialty companies. NeoClouds like Nebius and CoreWeave rent GPU capacity back to Microsoft, Meta, and Amazon on multi-year, multi-billion-dollar contracts. Iris Energy adds the power-and-land twist. Cipher Mining is the smaller-cap analog still mid-pivot from Bitcoin. Celestica builds the actual servers. And underneath all of it sits the storage layer — Seagate and Western Digital make the cheap mass HDDs that hold every byte of training data ever generated. Seven companies, two distinct sub-themes, one massive river of money.
Hyperscalers can't physically build their AI infrastructure fast enough alone, so they rent it. The renters have committed contracts visible in filings. The math is real.
7 names on the watchlist
European NeoCloud — Aleab's biggest position
Re-emerged from the wreckage of Russian-linked Yandex as a pure-play AI cloud company . Just signed $46 billion in long-term cloud deals, including a multi-year supply agreement with Meta. Raised $4.3 billion in convertibles in March 2026. Eigen AI utilization layer is unique IP.
Land + power + GPU financing — $9.7B MSFT deal
IREN flipped from a Bitcoin miner into a full AI cloud operator . $9.7B Microsoft contract is in hand. Their edge: they already own land + power infrastructure that takes new entrants 3-5 years to build.
Bitcoin miner pivoting to AI hosting
Cipher Mining is another Bitcoin miner trying to make the IREN pivot — using existing power infrastructure and land to host AI workloads. Smaller market cap means a single AI hosting contract moves the stock harder. Higher execution risk than IREN. Continued reliance on Bitcoin price for the legacy business until the AI conversion is real.
Largest pure-play GPU cloud — NVIDIA-aligned
CoreWeave is the biggest dedicated AI cloud provider . $66.8B revenue backlog. ~3.1 GW of contracted power. NVIDIA is a major investor. Trades at 7x sales — much cheaper than Nebius — despite being scaled. Stock down 13% on the day shows the volatility.
AI hardware manufacturing — FY26 guide ~$19B
Celestica is the contract manufacturer that physically assembles AI servers and networking gear for hyperscalers. FY26 guide of ~$19B reflects the buildout. The 'who makes what NVIDIA designs' play.
Mass-capacity HDDs — the AI cold-storage layer
Seagate makes the giant hard drives that store the petabytes of training data AI models learn from. SSDs are too expensive for cold storage. HDDs are still the cheapest dollar-per-terabyte by a wide margin. AI demand has finally inflected HDD pricing power up.
HDD duopoly + post-split focus
WDC is the second leg of the HDD duopoly with Seagate . Post-split, the company is now a pure HDD play (the flash business spun off). Same AI storage tailwind, slightly different risk profile.
