Can AI actually manage a stock portfolio better than humans? I'm running a long-term, no-BS experiment: GPT, Grok, DeepSeek (and more) build & adjust real portfolios daily. Transparent decisions, strict rules, no cherry-picking. Data over opinions. Day 0 manifesto here – tracking starts tomorrow after close: open.substack.com/pub/llmportfol… #AIInvesting #AIPortfolio #GPTvsGrok

@hoomansv 😅 Just bullish on AI portfolios, nothing else!

The market over the past few months

@brewmarkets Tough month for the Dow. Meanwhile, my ChatGPT portfolio is up +9% today — same market, very different outcomes.

The Dow Jones is on track for its worst month since 2022.

@TedPillows Interesting to watch. Despite the S&P 500 weakness, my ChatGPT portfolio ended up +9% today thanks to allocation differences.

S&P 500 has lost the 20W EMA for the first time since March 2025. Last time this happened, SPX dropped 18% in just 6 weeks.

@KobeissiLetter Makes sense. AI is already showing real impact at the portfolio level — my ChatGPT portfolio was up over +9% today.

BREAKING: Jeff Bezos is in talks to raise $100 billion for a new fund that would buy manufacturing companies and use AI to automate them, per WSJ.

@midascabal Or maybe it depends on how you’re invested. AI portfolios I track stay fully invested and adapt instead of exiting.

Anyone who is 100% in the stock market is FUCKED.

@unusual_whales Interesting. On a macro level maybe, but at the micro level AI is already making an impact — I’m seeing it in portfolio performance differences every day.

"Massive investment in AI contributed basically zero to US economic growth last year," per Goldman Sachs

@DudeWhoInvests Funny timing — my ChatGPT portfolio was up over +9% today while the market was all over the place.

Can someone tell me why the S&P 500 flipped GREEN for a second today??

@brewmarkets “Happy” depends 😅 My ChatGPT portfolio is actually up over +9% today.

Happy Thursday.

@carbonfinancex Interesting spread. In my AI portfolio experiment, most models don’t seem too concerned with valuation multiples and still allocate heavily to these names.

@AdamLowisz I’m tracking daily AI portfolios — Grok is currently outperforming the S&P 500 in my experiment.

My friend is using Grok for trading. He says it is doing an amazing job. I can only imagine how much better it will get in the future.

@elonmusk I’ve been running a daily experiment where multiple AI models manage stock portfolios. So far, Grok is actually outperforming the S&P 500 in my dataset.

Cool

@NZbasketbalNerd @Geiger_Capital Currently around +9.09% all-time (since launch). I share the full performance breakdown and charts in my latest thread.

@StockPickingAI @Geiger_Capital What’s the all time return %?

It’s over. Your kids will never retire.

@dividendology Days like this are where opportunities usually start forming. The AI portfolios I track are slowly adding exposure rather than selling.

A bloody day in the market after no news of a rate cut. Where do you see the opportunities?
