After three months the AI-controlled Polymarket wallet…

Brief

An AI-controlled wallet on Polymarket (0x9f5ffe76a818dce37c70f947998b52b70671a008) ran for three months, executing 65,840 trades and amassing $239,912. It functioned as a continuous market-maker, buying both sides of events to capture a few-cent spread and earning tiny fractions of a cent per trade through nonstop order-book presence and ultra-fast repricing.

Why it matters

After three months the AI-controlled Polymarket wallet 0x9f5ffe76a818dce37c70f947998b52b70671a008 held $239,912 across 65,840 trades and operated every minute with no days off.

Key details

  • The bot acted as a market-maker, buying both sides of the same event and capturing the spread by picking up contracts a few cents cheaper then selling them back, earning fractions of a cent per trade that compound over 65k+ trades.
  • @xmayeth says the strategy requires nonstop presence in the order book and repricing faster than the market (humans get tired); the author invites others to reverse-engineer the agent and notes it made another dozen trades while reading the post.
Source evidence

Someone gave an AI a wallet, dropped it onto Polymarket and said "go make money."

Three months later the account sits at $239,912 across 65,840 trades, without a single day off.

It doesn't care which way the price goes. It buys both sides of the same event - up and down.

Whatever the outcome, it ends up in profit.

The trick is simple, like a currency exchange. The buy price and the sell price are always a little apart.

It picks up a contract a couple of cents cheaper, then hands it right back to the market.

Each trade earns a fraction of a cent. But there are 65,000 of them, and that's where the whole sum comes from.

You can't click that by hand. To catch that fraction you have to sit in the order book non-stop and reprice faster than the market moves.

People get tired, distracted, go to sleep. This one didn't miss a single minute in three months.

By the time you finished reading this, it made another dozen trades.

Go scroll through its trades yourself. It's more interesting than any chart.

Send this post to your own AI agent for reverse-engineering - let it try to build one like this.
