On May 22, 2026, Indonesia's Ministry of Communication and Digital Affairs (Komdigi) blocked nationwide access to Polymarket, the crypto-denominated prediction market. Director General of Digital Space Supervision Alexander Sabar called the platform an "online gambling site disguised as a prediction market," declaring that "the government will not allow any form of online gambling in Indonesia." The trigger was a contract listed on May 21 allowing users to wager on whether President Prabowo Subianto would step down by May 31, June 30, or December 31, 2026 — three resolutions that priced his early exit at roughly 1%, 2%, and 18%, on combined volume of about $46,000. Komdigi added that it is tracing and restricting social media accounts affiliated with the platform.
Indonesia did not invent a new tool for this. It applied an existing one — the Penyelenggara Sistem Elektronik (PSE) platform-licensing regime built on Ministerial Regulation 5 of 2020 (MR5) — to a new category of service. That move is worth examining on its own terms, because the PSE regime was designed to license platforms operating in Indonesia, and is now functioning as a discretionary content filter that reaches into politically sensitive speech.
The case for the block, fairly stated
Indonesia's concern about online gambling is not manufactured. Komdigi has worked with the financial intelligence unit PPATK on a sweeping anti-betting drive that, by official accounts, has frozen tens of thousands of accounts tied to online wagering rings in 2026 alone. Household debt, predatory affiliate networks, and youth exposure to fast-cycle betting products are genuine social harms, and Indonesia's Criminal Code has long prohibited gambling without a specific carve-out for blockchain settlement. From a regulator's perspective, a service that takes money, pays out on uncertain future events, and markets itself with sharp odds tables is a duck regardless of whether it calls itself a market. The CFTC, the SEC, and Brazil's finance ministry — which blocked 27 prediction platforms including Polymarket and Kalshi in April 2026 — have arrived at variations of the same conclusion.
So a prediction-market block is not, by itself, evidence of bad faith. The harder question is what tool you reach for and how proportionate it is.
What the PSE regime actually does
MR5 requires every "private electronic system operator" reachable from Indonesia to register with Komdigi, appoint a local point of contact, and respond to takedown orders. Non-urgent removals must be completed within 24 hours; "urgent" content within 4 hours. Failure to comply triggers blocking. As civil society groups including SAFEnet and EFF documented when MR5 was issued, the regulation uses the phrase "access termination" 65 times and leaves the standard for blocking effectively undefined — the executive may treat content as "unlawful" or community-disturbing on minimal procedural scaffolding (SAFEnet position paper on MR5; EFF, 2021).
In July 2022, the same regime was used to take down PayPal, Yahoo, Steam, Epic Games, Dota 2, Counter-Strike: Global Offensive, and Origin overnight — not for any specific harmful content, but for paperwork. The fallout was severe enough that Komdigi briefly reversed the PayPal block to let users withdraw funds. The episode established two things: the PSE regime can flip large foreign platforms off in hours, and the standard for that switch is administrative discretion rather than judicial finding.
The Polymarket order shows the second feature working as designed. The block was announced, by Komdigi's own framing, days after a politically inflammatory contract appeared. The legal basis cited in the ministry's communications is the general prohibition on online gambling, but the operational basis is the PSE regime's blocking authority, which does not require a court order, an evidentiary hearing, or a finding of imminent harm.
The political-speech edge case
The Prabowo contracts are the part of this story that should make even pro-regulation observers pause. Prediction markets are not just gambling instruments — they are aggregated forecasts about political outcomes, and the public reads them as such. A contract that prices a sitting president's early exit at 18% by year-end is a piece of political commentary, however small the dollar volume. Polymarket's overall economic footprint in Indonesia was negligible: $46,000 across three contracts is rounding error against the country's domestic illegal-betting market. The proportionality question is hard to dodge: was the block aimed at gambling harm or at the embarrassment of a market that publicly quoted odds against the head of state? Komdigi's decision to extend enforcement to "affiliated social media accounts" — i.e., accounts that discussed or shared the contract — sharpens the speech concern considerably (CoinDesk; SCMP).
A more proportionate path
A proportionate regulator with the same gambling concern could have done several things short of a full nationwide block. It could have demanded geofencing of Indonesian IPs, as Polymarket already does for U.S. users under its CFTC settlement; required exclusion of political-event contracts of Indonesian officials; mandated KYC and deposit caps; or pursued the on-ramps used by Indonesian residents to deposit USDC. Each is more administratively burdensome than blocking, which is precisely why blocking has become the reflex. But the reflex has costs: it pushes users to VPNs, weakens Indonesia's bargaining position with platforms that do want to comply, and sets a precedent that politically sensitive analytical services — election-modelling sites, polling aggregators, financial research platforms — can be removed by ministerial letter.
Proportionate regulation of prediction markets is achievable. Carving political-event contracts out of legal markets, as the CFTC has attempted, is one option; licensing them under securities or commodities frameworks, as some U.S. and European observers have proposed, is another. None of those paths require the PSE regime's hair-trigger blocking authority — and none ask the public to trust that the next contract removed will not be removed because a minister found it personally inconvenient.
