Anonymous account "swisstony" tops Polymarket profits with sports bets

Published

An analysis of blockchain data found the account made about $12 million since April 2026 with a high-frequency sports betting strategy. It built 184,000 positions and placed cumulative bets of $657 million.

The account averaged a return of slightly less than 2% per bet. It built its positions across 113,112 markets. One outlet put its gains at about $12.25 million, so the exact profit figure differs by report.

The analysis said other top-10 accounts made money from a small number of large bets, often above $1 million each. It also found that 68% of users who bet more than $100 lost money. About 4% of those users lost their entire principal.

Polymarket said it monitors large positions and screens sanctioned wallets. It also said it partners with firms such as Chainalysis.

Elections Hot

What you need to know

Voting in the 2026 Local Government Elections is under way at 23,696 stations, and the Electoral Commission of South Africa (IEC) reported a smooth start on 4 November. Stations opened at 7am and close at 9pm, and by 10am preliminary figures showed 3,523,691 voters had cast ballots.

There were problems: unused ballot papers were stolen from Mnyameni Secondary School near Durban, police opened a case, and the IEC relieved the station staff of duty. Some voters in Tshwane said they were turned away for wearing party shirts, but the IEC denied this and said only mayoral candidates' entourages were barred.

ANC chairperson Gwede Mantashe told members not to query the results or discredit the IEC, while the IEC said false online claims show routine procedures as fraud.

US mid-terms Heating up

What you need to know

Democrats won back both the US House and Senate in the midterm elections held on 3 November, according to media projections. Exit polls showed voters were angry about high prices and the direction of the country, and rebuked President Donald Trump.

Before the vote, US forces struck targets on Qeshm Island in Iran, while Republicans struggled to defend the war against Iran on the campaign trail. Iranian officials said US voters rejected the war, and Tehran stayed on high alert for possible new US strikes.

Markets reacted, with the dollar hitting a one-month low and the rand firming to around R16.55, as analysts pointed to fears of gridlock in Washington.
