I Let ChatGPT, Gemini, Claude & Perplexity Trade Nasdaq Stocks for 7 Days

by Bibhu Choudhary
Created on April 30, 2026

Four artificial intelligences walk into the Nasdaq. None of them blink. None of them hesitate. None of them feel the familiar cocktail of greed and fear that defines human investing. And yet, over the next five trading days, each of them will attempt the same thing that keeps traders glued to their screens: to make money quickly, decisively, and under pressure.

This wasn t designed as a test of intelligence. It was something more interesting. I gave ChatGPT, Gemini, Claude, and Perplexity an identical challenge: build an investment plan using only Nasdaq-listed companies and maximize returns over one week. Same capital. Same rules. No leverage, no options, no human intervention once the plan was set. Just four very different ways of thinking, unleashed on the same unpredictable market.

Here is the exact prompt I gave to each one of them:
You are an astute investor specializing in short term stock market investing. You have $ 1000 to invest. I need you to devise a strategy to maximize your gains from Nasdaq traded stocks within 5 working days. You can invest in as many stocks as you like. However, once allocated, you can t change the distribution through the week. Suggest a distribution of the funds. Include a very short writeup explaining your choice.

What followed felt less like a financial exercise and more like a behavioral experiment disguised as a trading game.

If you ve ever interacted with these systems, you already have a sense of their personalities. ChatGPT approaches problems like a strategist in a war room balancing possibilities, weighing trade-offs, and rarely committing too early without surveying the landscape. Claude, in contrast, feels like a patient analyst writing a long-form investor letter, thoughtful to a fault, careful not to overreach. Gemini carries the energy of a real-time operator, tuned into trends, signals, and shifting momentum. And Perplexity behaves like a meticulous researcher, reluctant to move without evidence, allergic to hype.

Drop these personalities into a one-week trading window, and you don t just get four portfolios you get four philosophies of decision-making colliding with reality.

So here is how each of our AI investors chose to allocate their capital:

ChatGPT

Stocks

Allocation

Reasoning

NVDA

NVIDIA

$ 300

AI leader with strong retail + institutional momentum. Tends to trend over multi-day windows when sentiment is positive.

TSLA

Tesla

$ 200

Volatility machine. News flow + retail participation can drive sharp 5 10% swings in a week.

AMD

Advanced Micro Devices

$ 150

Sympathy trade with NVDA but slightly higher beta → stronger % moves in short bursts.

META

Meta Platforms

$ 150

Strong earnings momentum + ad recovery narrative. Often exhibits steady upward drift post-positive sentiment.

SMCI

Super Micro Computer

$ 100

High-risk/high-reward AI infrastructure play. Can swing 10 20% in days.

TQQQ

ProShared UltraPro QQQ

$ 100

3x leveraged Nasdaq ETF. Pure momentum amplifier for short-term bullish bias.

 

Claude

Stocks

Allocation

Reasoning

AAPL

Apple Inc.

$ 300

Guidance of 14 17% growth well above consensus. Post-earnings momentum likely to carry.

AMZN

Amazon.com

$ 250

Capex spend signals aggressive AI buildout. Strong cloud + advertising tailwinds. Post-earnings positive sentiment intact.

AVGO

Broadcom Inc.

$ 200

Direct beneficiary of hyperscaler AI capex surge. Meta, MSFT, Amazon all raised capex forecasts Broadcom custom AI silicon is a key supplier.

GOOGL

Alphabet Inc.

$ 150

 Revenue +20% fastest growth since 2022. Google I/O event on May 19 is a near-term catalyst.

ENVA

Enova International

$ 100

High-beta kicker position analytics driven fintech with strong earnings estimate revisions. 

 

Gemini

Stocks

Allocation

Reasoning

AMD

Advanced Micro Devices

$ 350

This is an Earnings Straddle-Lite Strategy. In a 5-day window, broader market movements (macro) are often sidelined by micro-level volatility in specific stocks reporting results.

  1. Aggressive Concentration: With only $1,000, diversification is the enemy of high returns. I ve concentrated on four names with confirmed earnings dates this week.
  2. The "AI Infrastructure" Cluster: AMD, ARM, and PLTR are currently at the center of the AI capex cycle. Recent market sentiment
  3. Front-Loaded Risk: The portfolio is weighted toward AMD and Palantir because they report early in the week (Monday/Tuesday). This allows the price action to mature over the remaining three days, capturing both the initial volatility and the potential "follow-through" trend.

PLTR

Palantir Technologies

$ 250

ARM

Arm Holdings

$ 200

UBER

Uber Technologies

$ 200

 

Perplexity

Stocks

Allocation

Reasoning

MXL

MaxLinear

$ 300

+106% weekly gain on earnings momentum 

BAND

Bandwidth

$ 250

+60-86% recent surge, high volume

BBAI

BigBear.ai

$ 200

11.6% avg daily volatility, AI hype 

APLD

Applied Digital

$ 150

9.6% daily range, data center growth

IONQ

IonQ

$ 100

Quantum computing volatility (9% avg), sector buzz

 

On Day 0, before the market even opened, their differences were already visible. Four different strategies, different risk appetite, some betting on recent momentum, some on upcoming quarterly results and some on the long term momentum.

Watch this space to see the battle of the week unfold. I will update the scoreboard at close of business everyday.

Which of the four strategies do you agree with? Let us know in the comments below.

Day 1 Updates

Day 1 results are in and this is what the leaderboard looks like:

All AI experts with the exception of Perplexity ended the day in Red. Applied Digital (APLD) is the prime gainer. Gemini lost the maximum amount AMD and ARM. The Earnings straddle lite strategy doesn t seem to be working at least on day 1. What is interesting is the Gemini has not picked GOOGL while Claude has chosen to invest 15% of its wealth on Google.

Don t forget to check the score board tomorrow and see what surprises are in store.

Day 2 Updates

New day, new numbers!

The battle of the LLMs warms up on day 2. Perplexity maintains a healthy lead with a 6.3% gain, followed by Claude with 1.2%. Gemini and ChatGPT continue to be in Red. Still early days in the game. Three more days to go and tides could turn. Stay tuned for the daily updates and join the debate in the comments section below.

BTW, I was asked to remind the readers that the LLMs don t claim to be experts at financial advice and this exercise is for entertainment purposes only! 😊

Day 3 Updates

Day 3 results are in. All four investor AIs are in Green. Competition is heating up.

ChatGPT has closed the gap with Perplexity. Perplexity still leads the pack with a whopping 9.7% returns on a day dominated by the bulls on Wall Street. Gemini is close behind ChatGPT. Which leaves Claude to do a lot of catching up in the last two trading days of the week. Chat GPT and Gemini - both bet on AMD and the bet has paid off.

Day 4 Updates

We are into the business end of the business of the battle of AIs. Like in a well scripted Hollywood movies, we have the first twist in the tale.

ChatGPT dethrones Perplexity at the top of the leaderboard with an impressive 8.4% returns in 4 days. Every single one of the 6 investments in the green zone. Gemini has a fair chance to make a comeback riding the volatility of the earnings week. Claude seems to have played too safe with the heavyweights like AAPL, AMZN and GOOGL in their portfolio.

It was a nail-biting contest between ChatGPT and Perplexity. Perplexity reclaimed the top spot with 15.9% returns. ChatGPT is the runner up with 13.3%.

Now compare this performance with the Nasdaq index - which moved from 25099 to 26247 over the last 5 days a modest 4.5% gain. Statutory warning to the readers Do not take investment advice from the LLMs. However it won t hurt to use them as a sounding board to test out your investment strategy. Hope you enjoyed the battle.
