Solana eats Ethereum's lunch this cycle
Solana ecosystem tokens will outperform ETH on a risk-adjusted basis this cycle due to superior throughput, fee revenue, and developer momentum.
Result
If held over the last 3 months (Jul 14, 2026 – Oct 13, 2026): −8.7%. Over the same days: ETH +40.3%, BTC +32.6%.
What it holds
- Solana Base Layer, 40% of the money: SOL, JTO. SOL captures the lion's share of Solana ecosystem value as activity and fees compound on the chain.
- Solana DeFi & DEX, 30% of the money: JUP, AERO, PYTH. Solana-native DEXs and DeFi protocols are stealing volume and TVL from Ethereum counterparts.
- ETH Relative Short, 15% of the money, −65.2% over 3 months: against ETH, against ARB. ETH underperforms as Solana siphons developers, users, and mindshare this cycle.
- Cash, 15%.
The plan behind it
The core bet is long SOL as the base layer capturing value, paired with top Solana-native DeFi and infrastructure tokens. ETH is shorted as the relative loser — not collapsing, but underperforming. JUP and AERO represent Solana DEX dominance eating into Ethereum DEX volume. JTO captures Solana liquid staking growth. Cash is kept for drawdown reloads given crypto volatility.
What would prove it wrong: SOL/ETH ratio breaks back below its last cycle high and Solana TVL falls below 30% of Ethereum TVL for two consecutive months.
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.
