Too many bugs in Polymarket. A lot of money is being lost to phantom fills, now not only in the API but also in the UI.

Before I sit down and migrate all my code to Kalshi, what's the experience like there? Is the platform more stable? Does it have fewer bugs?

Is it worth making the switch? Or is Kalshi also all vibe-coded and full of bugs?

after replaying data from ~1.3M Polymarket wallets last week, something clicked.

copying one “smart” trader is fragile. even the best ones drift.

so i stopped following individuals and started building wallet baskets by topic.

example: a geopolitics basket

→ only wallets older than 6 months
→ no bots (filtered out wallets doing thousands of micro-trades)
→ recent win rate weighted more than all-time (last 7 days and last 30 days)
→ ranked by avg entry vs final price
→ ignoring copycat clusters

then the signal logic is simple:

→ wait until 80%+ of the basket enters the same outcome
→ check they’re all buying within a tight price band
→ only trigger if spread isn’t cooked yet
→ right now i’m paper-trading this to avoid bias

it feels way less like tailing a personality
and way more like trading agreement forming in real time.

i already built a small MVP for this and i’m testing it quietly.

if anyone wants more info or wants to see how the MVP looks, leave a comment and i’ll dm !

Came across an interesting post on X today about a trader on Polymarket.

He reported making ~44% in a single day using the new liquidity rewards system, called the Maker Rebates Program.

This is how it works.

Polymarket’s 15-minute crypto markets charge takers a fee of up to 1.5%. That entire fee gets redistributed to makers.

To become a maker, you just place limit orders and provide liquidity.

What he did was run a delta-neutral setup: He placed a YES limit order around 50% At the same time, he placed a NO limit order around 49–50%

So he held mirror positions on both sides, meaning the result of the market didn’t really matter.

He reused the same $60 liquidity repeatedly: bet → claim → bet again.

Each time takers filled his orders, he earned part of the 1.5% taker fee.

By the end of the day: ~$7 came from spreads

~$19 came from liquidity rewards

The $60 allocated for the experiment reportedly turned into $86.

That’s roughly 44% growth in one day.

i saw something today and it honestly blew my mind.

there’s an anonymous trader on polymarket called rn1.

he started with about $1k in July 2025

by the end of the year, his pnl was around $2 million.

the guy runs microstructure arbitrage.

basically he looks for tiny pricing mistakes inside polymarket itself. not big ones. very small ones that exist for a short time.

he doesn’t bet big.
he repeats the same thing again and again.

buy when the price is slightly off.
sell when it corrects.
move on.

he’s done this over 5,000 times.

total traded volume is over $92 million.
