Not just AI brands.
AI bottlenecks.
STACK favors durable control points: technology that is difficult to replace, benefits from rising AI demand, and occupies a distinct job in the ecosystem.
Models need a way into daily life.
Cloud platforms, enterprise software and consumer products translate capability into recurring revenue.
Back the system, not a single prophecy.
The basket spreads exposure across designers, manufacturers, hyperscalers, data infrastructure and applications.

Hypothetical/backtested performance applies the official STACK v1.0 target weights to historical closes sourced from Yahoo Finance. No rebalancing, fees or dividends. ARM’s 3% sleeve is modeled as cash until its first available close on Sept. 14, 2023, then invested. SPY is the S&P 500 proxy. Actual STACK performance begins September 9, 2026. Educational concept only; not investment advice.
OAI
The private-company signal
Why OpenAI matters—but is not a holding.
OpenAI helped turn generative AI into a mass-market category and remains central to the ecosystem. But it is privately held, so an investable public-equity index cannot buy it directly. STACK captures parts of that influence through Microsoft’s partnership and the wider infrastructure demand OpenAI helped ignite.
