Indonesia blocked the decentralized prediction market Polymarket after the platform listed a controversial contract wagering on whether President Prabowo Subianto would leave office before his democratic term officially concludes in 2029. The country’s Ministry of Communication and Digital Affairs, known locally as Komdigi, classified the platform’s forecasting mechanisms as illegal online gambling operating under the guise of an analytical information tool.

The offending contract went live on May 21, the same week President Prabowo announced aggressive plans to centralize state control over major national commodity exports. While the market drew a modest $46,000 in total trading volume and priced the odds of an early exit at a nominal percentage, it triggered an immediate regulatory response.

Under strict Indonesian law, all forms of online gambling are completely illegal, meaning a foreign Web3 platform hosting financial wagers on the nation’s executive job security was never going to slip past state censors.

A Prediction Market or a Bookie

Komdigi’s logic was blunt. A contract that pays out on an uncertain future event, with real money staked on the outcome, is a bet. Polymarket settles those bets in crypto, which puts it squarely in the same offshore online gambling bucket Indonesia has spent the year trying to wall off. Ministry official Alexander Sabar said the platform’s activity contained betting and speculation over events that are inconclusive.

Indonesia isn’t alone here. Polymarket has run into blocks or restrictions in Singapore, Brazil and India, and faces friction in Thailand and Taiwan. The prediction-market model keeps colliding with national gambling law, and regulators keep landing on the same answer.

The Bigger Crackdown

The Polymarket block lands inside a much wider enforcement push. Days earlier, on May 9, Indonesian authorities announced the arrest of 321 foreigners in a commercial building near Jakarta’s Chinatown, one of the largest illegal online-betting busts the country has run.

The ring operated at least 70 gambling websites aimed at players outside Indonesia, a classic offshore scam-compound setup. Most of those arrested were Vietnamese and Chinese nationals, with others from Laos, Myanmar, Thailand, Malaysia and Cambodia. Many had entered on short-term visas and overstayed, so immigration and money-laundering charges stacked on top of the gambling counts. Penalties run up to nine years in prison and fines reaching two billion rupiah.

Authorities have frozen tens of thousands of bank accounts this year as part of the same campaign, choking the money flows that keep these operations alive. The scale tells you this is no longer a fringe enforcement effort. Indonesia is treating offshore gambling rings the way it treats organized crime, with mass arrests, asset freezes and immigration sweeps running in parallel.

The platform’s defenders keep calling Polymarket a harmless forecasting tool. Jakarta has decided it’s a bookmaker. Right now Jakarta is the one holding the firewall.
