Summary
Bizety analysis of OpenAI’s October 2025 DRAM deals, calling them the “Dirty DRAM Deal.” Details how OpenAI signed preliminary agreements with Samsung and SK Hynix for ~900,000 DRAM wafer starts per month out of ~2.2-2.3 million global capacity, effectively cornering 40% of world supply. Frames the move as strategic resource denial rather than genuine procurement.
Key Points
- OpenAI went directly to wafer manufacturers rather than buying finished modules; reserved raw manufacturing capacity
- Global DRAM wafer production capacity estimated at 2.2-2.3 million starts/month (TechInsights/TrendForce)
- OpenAI’s deals alone consume ~40% of this capacity
- Samsung and SK Hynix reportedly did not initially realize OpenAI was signing parallel deals with both
- Spot DDR5 prices surged 50-100% immediately after deal details leaked
- HBM demand projected at 50%+ CAGR through 2027 (Yole Group)
- Framed as a “supply chain moat” — strategic denial that makes it harder for Meta, Google, Microsoft, and Chinese AI firms to scale hardware
- Author warns prices could remain artificially high until 2028 or beyond
Newsletter Angles
- This is the earliest detailed public framing of the deals as “strategic denial” rather than procurement — published December 2025, before the full cascade played out
- The “wafer starts vs. finished modules” distinction is editorially valuable: it clarifies that OpenAI was buying manufacturing time, not memory — a resource denial play
- Useful as a contemporary source to establish that the “dirty deal” framing existed before OpenAI’s subsequent spending cuts proved the deals were bluffs
Entities Mentioned
- OpenAI — the actor; signed the LOIs as part of Stargate initiative
- Samsung — one of two DRAM suppliers who signed deals
- SK Hynix — the other supplier; neither knew about the parallel deal
- Oracle — Stargate project partner
- SoftBank — Stargate project partner
Concepts Mentioned
- Chokepoint Control — the deals exploit market concentration to deny competitors resources
Quotes
Sources close to the deals suggest that Sam Altman’s AI powerhouse has effectively cornered a staggering 40% of the world’s projected DRAM manufacturing capacity for the coming years.
Notes
Published December 28, 2025 — roughly two months after the LOIs were signed. This is a real-time industry reaction piece, not a retrospective. The analysis correctly identified the strategic denial dimension before the demand collapse confirmed it. Sources cited include TechInsights, TrendForce, Yole Group, The Information, Bloomberg, and Reuters, though specific figures from paywalled research firms are noted as difficult to link directly.
