AI runs out of memory, chip makers cash in
Memory chips will be the next thing AI can't get enough of, so the companies that make them will win.
Result
If held over the last 3 months (Jul 24, 2026 – Oct 23, 2026): −21.6%. Over the same days: Chip stocks −7.0%, S&P 500 +4.0%.
What it holds
- Memory makers, 41% of the money, −17.1% over 3 months: MU (Micron), SKHX (SK Hynix), SMSN (Samsung), DRAM (Memory chip basket). The companies that make AI memory chips get paid first when supply is tight.
- Storage and Asian memory, 27% of the money, −34.9% over 3 months: SNDK (Sandisk), KIOXIA (Kioxia), WDC (Western Digital), EWY (South Korea fund). A memory shortage also lifts storage chips and the Asian markets that make them.
- Tool makers and AI buyers, 23% of the money, −19.8% over 3 months: LRCX (Lam Research), AMAT (Applied Materials), NVDA (Nvidia). Memory makers must buy more tools, while AI spenders feel the pinch.
- Cash, 10%.
The plan behind it
AI needs a lot of memory chips to run, and only a few companies make the best ones. If demand grows faster than supply, prices and profits should jump. The first group holds the memory makers directly. The second holds storage and Asian memory names that gain when the shortage spreads. The third holds the AI buyers and the equipment makers who feel the squeeze or sell the tools. The cash is there to buy more if prices dip, or to stay safe if we are wrong.
What would prove it wrong: Memory prices start falling and the big makers say supply has caught up with demand.
FAQ
Can I make one from my own idea?
Yes. Write what you believe in plain words at https://f.xyz/create. fxyz asks a couple of questions, builds the portfolio and shows how it would have done over the last 3 months.
Can I turn a post on X into a theory?
Yes. Reply to the post and tag @fxyzai. It tests the view in the post and replies with the 3-month result and a link.
What can it trade?
Stocks (Tesla, Apple, Nvidia), crypto (Bitcoin, Ethereum, Solana), pre-IPO companies (OpenAI, Anthropic), indices (Nasdaq 100, S&P 500), commodities (gold, silver, oil, copper) and currencies (EUR/USD, USD/JPY). One theory can mix them, and bet for or against any of them.
How does it react to news?
On each check it reads the last two days of news on its biggest holdings and says whether the idea still holds. It can make one small change at a time: trim or drop one holding by up to 5 points. On autopilot the change waits 10 minutes so the owner can skip it; otherwise it asks first.
How do I run it with real money?
For real money, tap Make it mine, open your copy and choose Use real money, with an exchange connected: Hyperliquid, Lighter, Lighter (Robinhood), Backpack, Pacifica or Binance. The money stays in your own account there. fxyz can place trades, but it can never withdraw.
Can the AI get it wrong?
Yes. fxyz's AI turns the idea into holdings, and it can get that wrong: add a coin or stock that doesn't fit, or miss one that does. Check the holdings before you put money in. In your own copy, ask its chat to add or drop any of them.
What do the 3-month numbers mean?
What $100 would have done holding this mix over the last 3 months, at real prices. It is a what-if, not a record: past or simulated results are no promise of future ones, and nothing here is investment advice.
