One Thing To Know
Memory crossed a valuation threshold that commodity cycles don’t explain
Micron and SK Hynix both crossed $1 trillion in market capitalization today — with Micron being the first pure-play memory company to reach that threshold, with SK Hynix following later in the day, doing so in the same session. Micron surged 18% after a UBS price target increase on AI memory demand; SK Hynix rose 5.72%, the same day that they released iHBM, an in-package thermal architecture for HBM5 — more details below. Two $1T milestones and a major product announcement, from the two companies that together supply essentially all of the HBM capacity in deployed AI infrastructure, on the same day.
Neither move reflects a typical memory cycle re-rating. HBM supply constraints are not clearing on the 2025 schedule: HBM3E remains in short supply at premium ASPs, HBM4 pricing discussions for 2027 delivery are already setting new floors, and the stacked die complexity of HBM4 and HBM5 makes capacity ramps inherently slower than logic. The structural conclusion the market is pricing: HBM is not a commodity constrained by capex cycles. It is the binding bottleneck in AI infrastructure, and the companies with yield-leadership in stacked DRAM are capturing durable pricing power.
What to watch: guidance language from both companies in upcoming quarters on when HBM supply growth begins to stabilize pricing.
Public Markets
Micron’s HBM3E is now priced at a premium ASP with the limited spot market fully absorbed, and preliminary HBM4 agreements for 2027 delivery are already in place. Revenue inflection on HBM4 volume begins in H2 2026.
SK Hynix joined the $1 trillion market cap club today on AI memory chip dominance, becoming the second memory company to cross that threshold in the same session as Micron. The same morning, SK Hynix released iHBM — a thermal architecture that places an Integrated Cooling Element (ICE) at the die-to-base interface inside the HBM stack, reducing thermal resistance by 30%, targeting HBM5. Cooling is moving inside the package rather than outside it, enabling HBM5 to push higher bandwidth without hitting thermal walls and reducing co-design burden on GPU makers. With roughly 62% of the HBM market, the $1T milestone and the iHBM announcement arriving together underline that supply leadership and technical roadmap leadership are compounding in the same company.
Today’s move is driven by a distinct catalyst from Friday’s: the market is now pricing the implication of Nvidia’s Vera CPU delivery to Anthropic, OpenAI, SpaceX, and OCI for agentic AI workloads. Jensen Huang’s framing of a $200 billion CPU TAM for agentic AI does not displace EPYC — it endorses the category. AMD’s data center CPU revenue was $3.7 billion in Q1 (+57% YoY), and EPYC holds the entrenched position in exactly the orchestration and agent-sandboxing workloads that Vera targets. Nvidia validating the market size is the most bullish possible signal for the incumbent.
Private Companies
Baseten fundraise
The Information reports today that Baseten is in talks to raise $1 billion at an $11 billion valuation—more than doubling the $5B valuation from its January 2026 Series E (IVP, CapitalG, $150M from Nvidia). A raise at $11B would mark Baseten’s fourth round in roughly 20 months and would be the largest single raise in the inference infrastructure category to date. The competitive backdrop has intensified since January: Modal, Together AI, and other inference platforms are each raising at elevated valuations, and Baseten’s production-grade model serving architecture has continued adding enterprise customers since the Series E close.
Fireworks AI fundraise
Reports today indicate Fireworks AI is seeking a $15 billion valuation in a new funding round—nearly 4x the $4 billion it achieved in its October 2025 Series C ($250M, led by Lightspeed, Index Ventures, and Evantic Capital). Amount and lead investors are not yet disclosed. The implied step-up reflects the premium the market is placing on multi-model inference platforms with enterprise revenue traction, consistent with how the inference infrastructure category is being valued across both public and private markets right now.

Intel partnership
Bloomberg today frames the confirmed Apple chipmaking deal — Apple contracting Intel’s 18A process for certain chips — as “the firmest stamp of approval yet on the Intel turnaround project.” Commerce Secretary Lutnick personally brokered the deal. Now, Intel 18A has its first named tier-1 external customer. If production scales to Apple’s 2027 device roadmap, Intel Foundry Services will cement its importance to the business. Intel stock is up 175% year-to-date.
