Polymarket is accessible in Indonesia — the platform does not geoblock Indonesian IP addresses. Indonesia is one of the world’s largest crypto markets by user count, with over 19 million crypto investors and a mature local exchange ecosystem. However, Indonesia’s strict gambling laws create significant legal risks for prediction market users. Here’s what Indonesian users need to know.
Current Status: Accessible
Indonesia is not on Polymarket’s geoblocked countries list. The platform is fully accessible from Indonesian IP addresses. Users can sign up, deposit, and trade on all available markets.
Indonesia’s crypto market has grown rapidly. As of late 2025, over 19 million Indonesians hold crypto assets, and total transaction volume across Indonesian exchanges hit IDR 482 trillion in 2025. Indodax alone recorded IDR 201 trillion in KRW-market volume — a 51% year-over-year increase. Awareness is extremely high: 93% of surveyed Indonesians are familiar with cryptocurrency.
That said, Indonesia has some of the strictest gambling laws in Asia. All forms of gambling are explicitly illegal, and enforcement has intensified significantly in 2025-2026. While Polymarket is not blocked, Indonesian users should carefully consider the legal implications.
The Legal Landscape
Gambling Laws: Strictly Illegal
Indonesia prohibits all forms of gambling — online and offline — under national law, rooted in both the Criminal Code and Islamic legal principles:
- Under the New Criminal Code (effective January 2026), private online gambling now carries the same penalties as public gambling — the previous “public place” requirement has been removed
- Penalties include up to 10 years in prison
- In 2025, authorities launched an Online Gaming Eradication Desk taskforce that made 259 arrests and blocked over 93,000 gambling sites
- Between September and October 2025, more than 2.1 million gambling-related posts and items were removed from digital platforms
- Police froze $9.5 million linked to illegal online gambling operations
Prediction markets are not specifically classified under Indonesian law, but given the broad prohibition on gambling and the aggressive enforcement stance, they would very likely be treated as illegal gambling.
Crypto Regulation: Major Transition
Indonesia’s crypto regulatory landscape underwent a fundamental shift in January 2025:
From Bappebti to OJK:
- Prior to January 2025, crypto was regulated by Bappebti (the Commodity Futures Trading Supervisory Body) as a commodity
- As of January 10, 2025, regulatory authority transferred to OJK (Financial Services Authority) under Government Regulation No. 49 of 2024
- Crypto is now classified as a digital financial asset (securities) rather than a commodity
- OJK oversees trading, offerings, custody, and consumer protection
Key Regulatory Points:
- Crypto is legal to trade as a regulated digital financial asset
- Crypto is illegal to use as payment — the Currency Law exclusively recognizes the rupiah as legal tender
- All exchanges must be OJK-licensed and comply with updated capital, consumer protection, and AML requirements
- Compliance with new rules was required by July 2025
Dual Legal Status
This creates an unusual situation for Indonesian Polymarket users: buying and holding USDC is legal (regulated financial asset activity), but using it to participate in what could be classified as gambling on an overseas platform enters dangerous legal territory.
How to Deposit from Indonesia
Indonesia has a well-developed local exchange ecosystem with strong IDR support. All major exchanges accept bank transfers from Indonesia’s largest banks.
Step 1: Buy USDC on a Licensed Exchange
| Exchange | Bank Transfer | E-Wallet | Notes |
|---|---|---|---|
| Indodax | BCA, Mandiri, BNI, BRI, CIMB | Limited | Largest Indonesian exchange; IDR 201T volume in 2025 |
| Tokocrypto | BCA, Mandiri, BNI, BRI | GoPay, OVO | Binance-backed; staking and NFT support |
| Pintu | BCA, Mandiri, BNI | GoPay | Mobile-first; full Indonesian language support |
| Rekeningku | BCA, Mandiri, BNI | Limited | OJK-registered; straightforward interface |
| Zipmex | BCA, Mandiri | Limited | Regional exchange with IDR support |
Deposit Methods Explained
Bank Transfer (Recommended): Transfer IDR from your bank account (BCA, Mandiri, BNI, or BRI are the most widely supported) to your exchange account. This is the most reliable method with the highest limits. Most transfers process within minutes.
E-Wallets (GoPay, OVO): Tokocrypto and Pintu support deposits via GoPay and OVO. Convenient for smaller amounts but may have lower limits than bank transfers.
Virtual Account: Most exchanges provide a virtual account number for each user, making bank transfers simple — just transfer to your designated VA number from any Indonesian bank.
Step 2: Transfer USDC to Polymarket
- Go to Deposit on Polymarket
- Select Use Crypto and copy your deposit address
- Send USDC from your exchange to the Polymarket address
- Choose Polygon for the lowest fees ($3 minimum, arrives in seconds)

Tax Implications
Indonesia overhauled its crypto tax framework in 2025 with the issuance of PMK 50/2025, effective August 1, 2025.
Income Tax on Crypto Transactions
| Platform Type | Tax Rate | How It Works |
|---|---|---|
| Licensed domestic exchange | 0.21% | Withheld automatically on each transaction |
| Foreign platform | 1% | Self-reported; significantly higher rate |
The tax is a final income tax applied to total transaction volume, not capital gains. For example, selling IDR 100 million worth of crypto on a licensed exchange incurs IDR 210,000 in tax (0.21%), withheld automatically by the platform.
For Polymarket trades, which occur on a foreign platform, the applicable rate is 1% of transaction volume — nearly five times the domestic rate.
VAT Treatment
Good news for traders: as of 2025, crypto assets are classified as securities (surat berharga), making crypto transfers exempt from VAT. This is a change from the previous regime where a 0.11% VAT applied.
However, crypto-related services (exchange fees, mining) are still subject to standard VAT.
Reporting Requirements
- All crypto transactions must be aggregated and reported on your annual SPT (tax return) by March 31
- This applies regardless of individual trade size
- Mining income is taxed under normal income tax provisions (5-35% for individuals, 22% for corporations)
Key Takeaway
The 1% rate on foreign platform transactions is punitive compared to the 0.21% domestic rate. This creates a strong incentive to use licensed Indonesian exchanges for on-ramp and off-ramp activities, even if you trade on Polymarket.
