There is an interesting account on Polymarket worth studying.

In December 2025, an investment of $2.9 million was made all at once, and then left untouched. As a result, it steadily earns about $600 per month, with no worries.

You might think this is the operation of a trading expert. But looking at the data reveals the truth—

This account only made one trade throughout the year, earning $40 from that trade. The real source of income isn’t from trading at all.

What’s the main source? The "interest" earned passively. A steady $600 income every month, without doing anything.

This is where it gets interesting. How many people stare at the screen all day, trade frequently, but end up earning less than simply depositing the principal and sleeping? The more trades, the smaller the returns. The ones who really make money are precisely those who just leave their money there and let it grow.

Platforms like Polymarket, a prediction market, can indeed provide significant passive income for liquidity providers. The key is to find the right approach, allocate the funds properly, and then just let time do the rest.
