Polymarket’s South African mayoral bets highlight regulatory gap

Polymarket’s mayoral betting markets are raising questions about whether South Africa’s gambling laws adequately cover offshore prediction platforms, as SABA pushes for tighter regulation.

Key takeaways:

• Polymarket’s eight South African metro mayoral markets recorded approximately US$379,000 in trading volume as of October 27, 2026.
• Johannesburg accounted for approximately US$135,000 in trading volume, compared with US$11,700 for Cape Town.
• Market prices implied a 96 per cent probability that Geordin Hill-Lewis would become Cape Town’s next mayor and a 52 per cent probability that Helen Zille would become Johannesburg’s next mayor.
• SABA chief executive Sean Coleman described prediction markets as exchange betting products operating under a different label.
• SABA argues that offshore prediction markets should be treated as part of the illegal offshore gambling market until a dedicated legal framework is established.

South Africa.- Polymarket users are trading contracts on who will become mayor in South Africa’s eight metropolitan areas ahead of the November 4 local government elections. The activity has renewed scrutiny of whether South Africa’s gambling laws adequately cover offshore prediction markets, reviving concerns raised by the South African Bookmakers’ Association (SABA) in July over how these platforms should be regulated.

At the time of TechCentral’s report on October 27, market prices implied a 96 per cent probability that Geordin Hill-Lewis would become Cape Town’s next mayor and a 52 per cent probability that Helen Zille would take the Johannesburg position. Johannesburg accounted for approximately US$135,000 of the combined trading volume, compared with US$11,700 for Cape Town. These figures reflect market activity at the time of reporting, not polling results or confirmed outcomes.

Unlike conventional bookmakers, Polymarket operates an order book in which users buy and sell contracts with one another. Contracts are priced between US$0 and US$1, with prices reflecting the market’s implied probability of an outcome. Winning contracts pay US$1 when settled, while losing contracts pay nothing. TechCentral reported that political-market taker fees can reach approximately 2 per cent of a trade’s value when a contract is priced near US$0.50.

The report added that South Africa was not among Polymarket’s restricted jurisdictions as of October 27 and that the country’s gambling legislation does not specifically provide for prediction markets.

South Africa’s gambling industry is overseen nationally by the National Gambling Board, while provincial gambling boards are responsible for licensing operators and monitoring compliance. How existing gambling laws apply to offshore prediction markets such as Polymarket remains a regulatory question.

Why is SABA challenging prediction markets?

The regulatory debate gained momentum in July, when more than R700,000 (US$43,000) had been wagered on Polymarket’s Johannesburg mayoral market. SABA cited the figure in its July 27 position paper, which called for prediction markets to fall under South Africa’s gambling laws.

SABA chief executive Sean Coleman said: “Prediction markets are, in substance, exchange betting products operating under a different label.” The association argues that operators should not be able to avoid gambling regulation simply by describing their products as forecasting or information markets.

SABA has raised concerns about consumer protection, responsible gambling, taxation, anti-money laundering compliance and market integrity. It has also warned that South Africa lacks a monitoring framework to detect manipulation in political prediction markets.

SABA maintains that offshore prediction markets should be treated as part of the illegal offshore gambling market until a dedicated legal framework is established.
