Does 0xinsider have a public Polymarket trading account?

Yes. The account is 0xinsider-com on Polymarket, and everything it does there is public. Since its first trade on August 11, 2026, it has traded 573 markets in 1,212 trades and about $202,000 of volume, and 216 of those markets were tennis.

It traded hard, then mostly stopped. 1,173 of the 1,212 trades came in August, 36 in September and 3 in October, the last on October 5. Anyone can check that on the profile without taking our word for it, which is the reason the account is public.

A public account shows you the bad weeks along with the good ones. Polymarket's own P&L line for it reached $8,372.82 on August 30 and stood at $7,524.17 on October 11, $849 lower, on almost no new trading. A screenshot of August 30 would have told a better story than the profile does.

What a public record proves is narrow. It shows what the account did and when. It does not show that the next trade will win, and 573 markets over two months is one short stretch of results.

It also shows where some of its money comes from. Every polymarket.com link on 0xinsider carries the referral tag 0xinsidercom, and referral rewards are paid into this account: 25 daily payments since August 24, $558.94 in all. Polymarket pays a referrer 10% of a new trader's net fees, for at most 30 days.

On its 0xinsider profile the account is graded B on settled profit: $5,798.25 realized over 564 decided markets at a 52.3% win rate. Polymarket shows the same wallet's markets and P&L with no grade on it, and no split by sport like the one in the chart above.

The split shows how thin the profit is. The five best markets made $7,510.95, more than the whole record's $5,800.19, and one fight, Serghei Spivac against Vitor Petrino at UFC Fight Night, made $1,810.68 on its own. Take away the five best markets and the account is down $1,711.

Polymarket gives this one account three different profits. Its leaderboard says $5,623.52, the P&L line on the profile says $7,524.17, and its user-stats breakdown says $6,405.06 all-in. Each counts different things, and the gap between the highest and the lowest is $1,901.

The biggest difference is fees. The account's trades made $7,446.89 before fees and paid $1,693.45 of it back, 22.7%. Rebates returned $167.28 and referral income added $484.34. Judge any wallet, this one included, on profit after fees, because a fifth of the gross can disappear on the way there.

So when you read a profile, check which number you are looking at: realized or open, before fees or after, and with or without income that did not come from a trade.
