An Arca-connected wallet incurred a $100,000 loss on Polymarket after betting on the outcome of a market regarding Microstrategy's Bitcoin sales. The wallet, which received deposits from and is signed by an Arca wallet, invested the amount on a "YES" position in the "Did Microstrategy Sell BTC By May 31st" market at an average price of 0.5 cents. The market ultimately expired at zero, resulting in a total loss for the wallet.
