From $500 to $973k in less than half a year.

An ordinary Chinese engineer, relying solely on math and AI, turned Polymarket into his printing press.
His name is Zhang Ran, 29 years old, previously just an average 9-to-5 programmer.
After paying off his mortgage and covering daily expenses, he had little left, with his biggest dream being financial freedom—no longer worrying about rent.
By the end of 2025, he gritted his teeth and transferred all his savings of $500 into Polymarket.
Everyone around him said, "Don’t be stupid, prediction markets are casinos, you’re throwing that money in and won’t even hear a sound."
Zhang Ran didn’t listen.
He spent a full two weeks building an fully automated trading system with Claude Opus 4.8.
The system automatically scans thousands of markets daily, scores each contract, and specifically targets those severely mispriced, low-probability events priced at only a few cents to a dozen cents.
Once it detects that the true probability is much higher than the market price, Hermes agents automatically place orders.
He hardly manually operated anything, just checked the data before bed each day.
In the first few days, the system only earned a few hundred dollars.
Zhang Ran once doubted whether he was dreaming.
But from the third week onward, things completely spiraled out of control.
His system’s win rate stabilized near 90%.
Each trade was bought at a very low cost, and once hit, it yielded explosive returns of 30 to 90 times.
The craziest trade, in particular, made him take off entirely:
On a monthly Bitcoin price range, he placed a heavy bet, earning $183k in a single trade.
Since then, profits rolled in like an avalanche.
The $500 principal rocket-launched to $973k in just a few months.
One of the top wallets on Polymarket:

Most outrageous of all, he himself almost sleeps, eats, and plays games every day.
What truly runs 24/7 nonstop is the cold-blooded math machine he built with AI.
Claude is responsible for finding opportunities, Hermes for executing, and all trades are quietly completed while he sleeps.
A few days ago, a fan followed his trades in real-time and made $72k overnight.
Zhang Ran now wakes up every morning, first glancing at his account balance with a faint look, then continues drinking his coffee.
He hasn’t quit his job, nor flaunted his wealth—just keeps optimizing that system to run more stably and faster.
The once-ordinary programmer who struggled over $500 for half a month now stands at a height most people will never reach in their lifetime.
