Summary
Medium analysis of OpenAI’s non-binding LOI and its market aftermath. Provides the most detailed available breakdown of the LOI’s financial terms ($71.3B over four years), the supplier production shifts it triggered, and the specific price data as the demand signal collapsed in March 2026. Published March 28, 2026 — three days after the TurboQuant announcement.
Key Points
- LOI valuation: $71.3 billion over four years — first source to put a total dollar figure on the deal
- LOI was non-binding; no legal obligation to purchase
- Samsung ramped HBM production toward 250,000 wafers/month (47% capacity increase)
- SK Hynix expanded to 620,000 DRAM wafers/month, significant share allocated for HBM conversion
- Together, suppliers reallocated up to 40% of advanced wafer capacity to AI-specific memory
- DRAM contract prices rose 171% YoY by Q3 2025
- 64GB DDR5 kit: $180 (May 2025) → $710 (December 2025) — 294% increase
- Quote validity windows compressed from 30-90 days to as little as 7 days; some distributors reported hourly spot pricing
- March 2026 collapse timeline: Stargate scrapped (Mar 6) → Sora shut down (Mar 24) → TurboQuant released (Mar 25)
- Samsung shifted 80,000 wafers back to DDR5 after demand signal collapsed (due to superior margins on standard DDR5 vs. now-oversupplied HBM)
Newsletter Angles
- The $71.3B four-year figure gives the “bluff” a dollar value — it’s not just 40% of capacity, it’s a $71B non-binding commitment
- The 7-day quote windows and hourly spot pricing are visceral operational details that convey the panic better than any price chart
- The Samsung wafer reallocation back to DDR5 is the bookend: the bluff is over, but the contracts Apple/Amazon/Microsoft signed during the panic are still locked in
- The March timeline (Stargate → Sora → TurboQuant in 19 days) reads like a controlled demolition of the original demand signal
Entities Mentioned
- OpenAI — signed the LOIs; demand subsequently collapsed
- Samsung — ramped HBM production, then shifted 80K wafers back to DDR5
- SK Hynix — expanded to 620K wafers/month
- Google — released TurboQuant (Mar 25)
Concepts Mentioned
- Chokepoint Control — the LOI mechanism as a market-shaping tool in a concentrated industry
- Jevons Paradox — implicitly: TurboQuant’s release was one of the collapse triggers, but contract prices held

Notes
Published March 28, 2026 — three days after TurboQuant, while the market was still digesting the demand collapse. Author cites TrendForce, Tom’s Hardware, Digitimes, Bloomberg, CNBC, and Google Research Blog. The $71.3B figure appears to be derived from analyst estimates of wafer pricing times the LOI volume over four years — not an official OpenAI disclosure. Treat as credible estimate, not confirmed.
