Someone on Reddit asked how SBet365 made $141k on Polymarket with only 3 trades.
I checked the receipts.
It's stupider and smarter than you think.
$25,090 deposited. $166,710 withdrawn. Net pulled out: $141,620.
Three predictions. That's the entire account history.
January 3rd, 2026. SBet365 buys "Maduro out by January 31?" Yes. At 11.3 cents. $9,999.96 in.
Same week. Buys "Maduro out by February 28?" Yes. At 18.3 cents. $15,089.90 in.
January 13th. One more bet: "Khamenei out as Supreme Leader by January 31?" Yes. At 20 cents. $4,000 in.
Maduro resolved Yes on both.
January win: $88,433.
February win: $82,276.
Total: $145,620 on $25,000 deployed.
Khamenei didn't resolve. $4,000 gone.
Net: $141,619.92.
Here's the math nobody's writing about.
11.3 cents on "Maduro out" implies the market gave it an 11.3% chance. SBet365 thought it was higher. Significantly higher. He wasn't predicting - he was finding a number he disagreed with and sizing into the disagreement.
$10,000 at 11 cents. If right: $88,400. If wrong: $10,000 gone.
Expected value only works if your probability estimate is better than the market's. His was.
2 wins. 1 loss. $141,620 net.
Most Polymarket traders diversify across dozens of markets to manage variance.
SBet365 did the opposite. He found one mispriced geopolitical event, sized in twice at different expiries, and walked away.
Concentration isn't reckless when the edge is real. It's just uncomfortable. Most people can't hold it.
The account has $0 in open positions. No active trades. He logged on, made three bets on one thesis, pulled $141k, and left.
That's not a strategy. That's a conviction.
