Broadcom's Samsung deal secures a dedicated production pipeline for its custom AI chips through the decade instead of fighting for TSMC capacity. The collaboration, estimated above $200B through 2030, gives Broadcom 2nm foundry, HBM and advanced packaging from the only company with all three under one roof. Samsung's execution is the wild card: SF2 yields run 50-60% versus about 90% for TSMC's N2, but a rise toward 70%+ over 18-24 months would unlock capacity TSMC cannot provide. x.com 

Broadcom gains capacity certainty, which is everything right now: Samsung's reported $200B AI chip partnership locks in Samsung 2nm+ foundry, next-gen HBM and advanced packaging for Broadcom's custom AI ASICs through 2030. x.com 

Broadcom's Jalapeño chip deal with OpenAI is already priced in and margin dilutive. OpenAI guides to about 30 GW by 2030; at 30-40% Jalapeño, that is 9-12 GW, matching the 10 GW deal signed in October 2025. Selling finished chips, Broadcom books full ASPs but fronts wafers, HBM and other costs, about $15 billion per GW or $25-45 billion a year, at 50-60% margins at best. FY27 guidance already tops $100 billion; the bull case is maybe $120 billion. Broadcom even lends OpenAI the build money. … Show more

Samsung Electro-Mechanics is emerging as an AI infrastructure titan as advanced substrates become the bottleneck for AI scaling. Per @jukan05, it will supply FC-BGA substrates for Broadcom's most advanced AI accelerators from the second half, joining NVIDIA, Google, Amazon and Apple. With Ibiden and Shinko at full capacity, it is the only tier-1 player with the capex to scale large-area substrates. AI servers also need 3-4x more MLCCs, where Samsung and Murata own the IP and earn premium margin. … Show more

Broadcom's integrated optics, electronics and packaging could lower custom-chip system costs because separate suppliers defend their margins. At similar valuations, it is preferred to Nvidia and has more room to beat expectations. Google TPU v8 shipments are estimated at 4.0M in 2026 and 9.1M in 2027, assuming Broadcom supplies the remainder after MediaTek's allocation. Anthropic financing adds value only if chip profit exceeds likely support payments and capacity costs. x.com  x.com 

Broadcom's valuation is likely to price in margin compression even if its actual margins hold, because squeezing leading suppliers' margins is the core aim of its four big customers. Chips are now production tools for cloud providers, so saving money is making money, and they shift to lower-margin second suppliers wherever they can. Real shortages make that hard near term, but the market prices it in early, as with Nvidia's 12x P/E. Trading can diverge from fundamentals. x.com  x.com  x.com  x.com 

Higher HBM stack requirements favor Samsung Electronics shares, even as the broader semiconductor industry suffers and DRAM is in dire straits. Daishin Securities says plans for 4-high and 6-high HBM in low-end inference appear shelved, while Nvidia's 8-high Rubin option appears dropped amid base-die supply constraints and customers' preference for bandwidth. x.com 

Prepaid contracts and demand-paced fabs weaken a broad 2028 memory-glut case. SK hynix says over half its 2027-28 capacity is signed with deposits; 'sold out through 2029' includes negotiations. Samsung targets 60-70% contracted capacity. Micron's three projects begin output in 2H28; tooling follows demand. Reuters says CXMT's 20-30%-yield HBM3E may ship this year to export-restricted Chinese buyers, but performs like older HBM3. Commodity DRAM risks 2028-29 oversupply; NAND could ease in 2H27. … Show more

Broadcom's $30 billion guarantee on Anthropic's chip debt is a binary bet. Per @HedgieMarkets, Apollo and Blackstone closed a $35 billion private credit deal in which an SPV buys Google's custom AI chips and leases them to Anthropic, and Broadcom's residual value guarantee covers the shortfall if Anthropic misses a payment and the chips lose value. As @HedgieMarkets puts it, the company whose CEO said productivity hasn't shown up now guarantees the hardware meant to produce it. x.com 

More memory CapEx may yield proportionally fewer bits as HBM consumes more wafer capacity, supporting SK hynix and Samsung's pricing. Both reported double-digit quarterly DRAM and NAND price gains; Samsung targets 60-70% of mid- to long-term capacity under LTAs. SK hynix has the stronger execution record, but Samsung could benefit enormously from conventional memory without winning HBM4. If trends persist, normalized margins could rise, though memory remains cyclical. x.com
