Six Five Pod Ep. 314: TerraFab, Memory's Comeback, and the Custom Silicon Debate

Patrick Moorhead and Daniel Newman cover Tesla and SpaceX's $16.8 billion TerraFab chip factory, Samsung's zHBM debut at FMS 2026, a week of frontier model launches, and a simulated debate for “The Flip” over whether custom silicon will capture the majority of AI workload dollars by 2028. The episode closes with earnings from SpaceX, Palantir, AMD, Astera Labs, IonQ, and Lattice Semiconductor.

The handpicked topics for this week are:

1. TerraFab Breaks Ground in Grimes County, Texas: Moorhead and Newman dig into Tesla and SpaceX's approved $16.8 billion TerraFab chip factory near Texas A&M, where Intel is confirmed as a digital foundry partner despite minimal SEC disclosure so far. Moorhead raises the open question of who handles the analog side of production that Intel doesn't cover, and Newman points to Musk's track record of hitting ambitious goals years behind his original stated timelines. Both hosts frame the investment as a genuine step toward expanding domestic chip manufacturing. (The Decode)

2. Samsung's zHBM Headlines a Blockbuster Memory Show at FMS 2026: The hosts cover the Future of Memory and Storage show in Santa Clara, where Samsung's BVNAND and zHBM concepts headlined alongside new announcements from Kioxia, SanDisk, and SK Group's high-bandwidth flash spec through OCP. Pat traces the industry's swing from oversupply and negative margins to today's memory shortage, driven by AI demand that has grown 5-10x faster than expected. Daniel adds that stacking memory directly on the accelerator, as zHBM proposes still needs to solve for the physical constraints of heat before it becomes production-ready.

3. Three Frontier Model Launches Land in a Single Week: Alibaba shipped Qwen 3.8 Max, DeepSeek released V4 Flash at 14 cents per million tokens, and Meta debuted its first coding agent, prompting a discussion on how fast the frontier is moving. Newman argues every company will need a new benchmark built around operational workloads and real-world token efficiency. He points out that Chinese model usage and frontier lab revenue are both climbing simultaneously, and makes the case that healthy frontier labs are essential to funding the open source models built in their wake.

4. Anthropic and AMD Both Make Moves on Custom Silicon: Anthropic confirmed it’s developing custom AI chips, reportedly with Samsung and reportedly Broadcom. AMD announced its acquisition of Taalas, a company that etches model weights directly into silicon for major inference speed gains. Patrick traces his own multi-year prediction that heterogeneous computing would become standard, pointing to Google's TPU program as proof it can work at scale. Daniel frames both moves as evidence that AI companies are racing to control total cost of ownership (TCO) as memory and compute costs keep climbing. (The Decode)

5. The Flip: Will Custom Silicon Capture the Majority of AI Workload Dollars by 2028? Patrick argues every frontier lab is now pursuing vertical integration, citing Anthropic's new chip program, AMD's acquisition of Taalas, and NVIDIA's $20 billion license of Grok's inference technology as evidence the shift toward specialized silicon has become a step function. Daniel counters that every lab building custom silicon is simultaneously signing record contracts with NVIDIA and AMD, arguing that compute itself functions as the real moat regardless of chip architecture. (The Flip)

6. SpaceX Posts 92% Growth in Its First Public Earnings Report: SpaceX's debut public earnings showed 92% growth, narrowing losses, and rapidly expanding AI compute revenue layered on top of its launch and satellite businesses. Daniel flags new AI deals with Google and Anthropic as driving much of that growth, while Pat highlights that the company's stated $100 billion run rate target depends heavily on December performance and questions how soon TerraFab related capex will hit the income statement. (Bulls and Bears)

7. Palantir Delivers Its Fastest Revenue Growth in Company History: Palantir posted 93% year-over-year growth and record commercial revenue, with CEO Alex Karp highlighting that no company at Palantir's scale has grown this fast before. Patrick points to the company's sovereign AI positioning as being well-timed given growing enterprise distrust of frontier model providers, and Daniel adds that 150% commercial growth is far outpacing other enterprise software peers. (Bulls and Bears)

8. AMD Posts Record Growth as Investors Expect Even More: AMD delivered record revenue and growth. Investors had priced in results closer to NVIDIA's historic beats, and capex nearly quadrupled without much detail on where the spending is going. Moorhead traces the increase to AMD building out Helios rack-scale systems ahead of shipping, and both hosts note the timing of Elon Musk's public NVIDIA endorsement landed awkwardly on AMD's earnings day. (Bulls and Bears)

9. Astera Labs Beats on Revenue and EPS as the Market Shrugs: Astera Labs beat on both top line and EPS, posting record growth off a still small base. Pat points out new CXL innovations unveiled at FMS as evidence of the company's position building connectivity infrastructure alongside Broadcom and Marvell. (Bulls and Bears)

10. IonQ Raises Guidance and Closes Its $1.8 Billion Skywater Acquisition: IonQ raised its FY26 guidance from $280 to $290 million and closed its Skywater acquisition, positioning the company as a vertically integrated quantum player across networking, sensing, and compute. Daniel notes IonQ is approaching a billion dollar annual run rate once Skywater is included, and highlights a new Anduril partnership as a notable expansion into defense. Patrick adds nuance to the "only quantum pure play with foundry assets" framing, noting other quantum companies maintain foundry relationships of their own. (Bulls and Bears)

11. Lattice Semiconductor Beats Across Revenue, EPS, and Guidance: Lattice beat on revenue, EPS, and guidance, growing 62% and closing its $1.65 billion AMI acquisition. Newman points to the company's data center AI segment growing 83% as FPGA content keeps expanding inside rack scale systems, and both hosts frame Lattice as approaching a billion dollars in annual revenue.
