A Polymarket Trader Proposed the Outcome of a Market It Was Trading
Polymarket ran a market asking whether MicroStrategy would sell any Bitcoin by May 31, 2026. An account that had traded the market was later named as the proposer of a No result. Then, 14 seconds after the proposal was recorded, it bought more No shares. The market ultimately resolved No.
Across its full history in this market, the account received about 61,713 pUSD more than it paid, with trading fees included. pUSD is Polymarket’s cash token. This net amount includes all its trades, cash returned from paired shares, and the final payout.
The cash result covers this account’s full history in this market, including trades before the proposal. Its scope is explained in Section 04.

01 · The same account was a trader and a proposer
On Polymarket, a proposed outcome starts the process of settling a market. Other participants can challenge it before the result becomes final. Polymarket describes this process in its resolution guide.
At 04:12:53 UTC on June 1, 2026, a proposal to settle this market as No was recorded. The proposal named the trading account as proposer. A different address submitted the blockchain transaction.
02 · It bought more No shares 14 seconds later
The account kept trading after the proposal. At 04:13:07 UTC on June 1, 2026, the same account bought another 2,213.26 No shares. That purchase came 14 seconds after the proposal was recorded. It was the account’s first No purchase after the proposal; it had traded the market before then.
The market later resolved No. The account then redeemed the No shares it still held.
03 · What the account paid and received
The 14-second purchase was part of a longer trading history. The account traded shares before and after the proposal. Overall, it paid about 680,070 pUSD more to buy shares than it received from selling them. That is its net trading spend, with trading fees included.
A trader who holds a matching Yes and No share can exchange the pair for the cash backing it. The account did this four times in May, before the proposal, and received about 7,200 pUSD. Later, after the market resolved No, the account redeemed its remaining No shares and received about 734,584 pUSD.
Together, the May returns and final payout exceeded that net trading spend by about 61,713 pUSD. This is the account’s net cash result across its full history in this market. The figures below are rounded to two decimal places.
| Step | Amount (pUSD) |
|---|---|
| Net cash spent on trading | −680,070.16 |
| Cash returned from paired Yes and No shares | +7,199.81 |
| Payout on remaining No shares | +734,583.70 |
| Net cash result | +61,713.35 |
By the final payout, the account held no remaining Yes or No shares from this market.
04 · What this does and does not show
The records show that a trading account was named as the No proposer and then bought more No shares. They do not identify who controlled the account. They also do not establish why it traded, whether the proposal changed prices or the final result, or whether anyone broke a rule.
This is one case, so it also cannot show how often traders propose outcomes on Polymarket.
The +61,713.35 pUSD figure is the cash difference across this account’s full history in this market. Polymarket describes pUSD as its collateral token. We report pUSD token units rather than verified U.S. dollars or the account owner’s total profit. Trading fees are included. The calculation excludes network fees, costs or returns from the resolution process, rewards, trades elsewhere, and outside hedges.
