Polymarket in China (2026) | Accessible — How to Deposit, Legal Status & Tax Guide

Polymarket is not geoblocked for China — it does not appear on Polymarket’s restricted countries list. But this status is misleading in practice. The Great Firewall blocks access to most foreign websites, domestic cryptocurrency trading has been fully banned since September 2021, and using unauthorized VPNs to circumvent the firewall is itself unlawful. For most mainland users, Polymarket is accessible only in name — reaching it requires substantial grey-market workarounds and carries real legal risk. This page lays out that reality honestly.

Current Status: Accessible (on paper)

China is not on Polymarket’s geoblocked countries list. The platform does not restrict Chinese IP addresses the way it blocks sanctioned jurisdictions.

The practical picture is very different. China’s Great Firewall filters and blocks thousands of foreign websites, and trading platforms with financial content — including Polymarket — are generally inaccessible from mainland networks without circumvention. Additionally, domestic cryptocurrency activity has been illegal since September 2021, which makes the on-ramp to Polymarket (buying stablecoins) legally problematic.

So the honest summary is: accessible on Polymarket’s list, but hard to reach and legally risky from the mainland. Users who do reach the platform typically rely on VPNs and grey-market crypto channels, both of which carry their own risks.

The Legal Landscape

The 2021 Crypto Ban

In September 2021, the People’s Bank of China (PBOC), alongside the CSRC and other regulators, issued a notice declaring that all cryptocurrency-related business activities are illegal in mainland China. The notice:

• Banned crypto trading, mining, and initial coin offerings (ICOs)
• Barred overseas exchanges from providing services to China-based users
• Directed financial institutions and payment firms not to facilitate crypto transactions

This was a continuation of earlier measures — the 2017 ban on ICOs and the closure of domestic exchanges. Since 2021, no legitimate mainland exchange has existed, and mining operations were pushed offshore.

The Great Firewall and VPNs

The Great Firewall of China (part of the country’s wider internet control system) blocks access to selected foreign websites and slows cross-border traffic. Polymarket and most crypto platforms fall outside what is routinely reachable.

Circumventing the firewall typically requires a VPN, but using an unapproved VPN is itself unlawful under Chinese law. Enforcement is selective — ordinary users are rarely prosecuted, but the legal exposure is real, and penalties for operating unauthorized VPN services have included prison sentences. As of 2026, working around these restrictions remains an individual risk decision.

The Grey Market

Despite the ban, a substantial grey market persists. Mainland users trade and remit value through:

• OTC and P2P channels — buying USDT or USDC via WeChat, Alipay, or bank transfers through informal brokers
• Multiple bank cards — traders often use cards from small rural banks to spread transfers and avoid monitoring
• Hong Kong and Macau — traveling to buy crypto in person or on regulated platforms

Hong Kong operates a separate, formally licensed regime. Under the framework that took effect in June 2023, the Hong Kong Securities and Futures Commission (SFC) licenses virtual asset trading platforms; the first retail licences went to HashKey Exchange and OSL in August 2023. But Hong Kong’s licensed ecosystem is legally distinct from mainland China, and mainland users accessing it still contend with the border and firewall.

Prediction markets specifically sit inside this broader cryptocurrency ban — there is no separate or more lenient treatment for Polymarket in mainland China.

Where Prediction Markets Sit

Because Polymarket is crypto-based and involves speculative event contracts, it falls under the combination of:

• The 2021 crypto ban (prohibits crypto transactions and overseas platform services)
• General prohibitions against unlicensed gambling and financial speculation in the mainland market

There is no regulatory pathway for a mainland prediction market operator, and none for split treatment of foreign platforms like Polymarket. The platform is not geoblocked by Polymarket itself, but it is effectively out of reach and out of compliance from the mainland.

How to Deposit from China

There is no legal domestic fiat-to-crypto on-ramp in mainland China. Users who trade rely on grey-market routes or Hong Kong. The table below reflects the reality of where mainland-adjacent users obtain stablecoins — not a recommendation, since these routes carry legal exposure.

Deposit Methods Explained

OTC / P2P (grey market): The most common mainland route. A user buys USDT or USDC from a broker or on a platform’s P2P marketplace, paying via WeChat, Alipay, or a bank transfer. This is fast but unregulated — counterparty risk, frozen-card risk, and legal exposure all exist.

Hong Kong licensed exchange: When physically in Hong Kong, a user can register with an SFC-licensed platform like HashKey or OSL, deposit HKD via bank transfer, and buy USDC. This is the closest thing to a regulated on-ramp, but it requires being in Hong Kong and has residency/KYC requirements.

Step 2: Transfer USDC to Polymarket

1. Go to Deposit on Polymarket
2. Select Use Crypto and copy your deposit address
3. Send USDC from your exchange or wallet to the Polymarket address
4. Choose Polygon for the lowest fees ($3 minimum, arrives in seconds)

Tax Implications

China does not have a dedicated crypto tax code, and the status of crypto earnings is unsettled given that crypto activity is itself prohibited.

• China’s Individual Income Tax Law applies a flat 20% rate to categories such as capital gains and incidental/occasional income, with progressive rates up to 45% on business income
• There is no clear, enforced framework for taxing crypto capital gains specifically — the legal ban creates ambiguity over whether gains are even recognized
• China takes a strict line on undeclared offshore income, and residents have reporting obligations on foreign earnings
• In practice, most mainland grey-market traders do not declare these earnings, which adds to the legal risk

Because the underlying activity is banned, the tax treatment is genuinely unclear and a matter of ongoing enforcement discretion. Do not rely on this summary for planning — consult a licensed tax advisor in your specific situation.

What You Don’t Pay

• There is no VAT on crypto-to-crypto transfers for individuals
• There is no dedicated crypto surcharge or wealth tax

Getting Started — an Honest Note

For mainland-based users, the honest answer is that “getting started” involves navigating a ban, the firewall, and grey-market rails. Steps like those below assume you are willing to take those risks, which many users living abroad or traveling to Hong Kong find far easier:

1. Understand the legal exposure — crypto trading is prohibited in mainland China, and using unapproved VPNs is unlawful
2. Obtain USDC via grey-market OTC/P2P or via a Hong Kong-licensed exchange (HashKey, OSL) when in Hong Kong
3. Deposit on Polymarket — transfer USDC via Polygon
4. Place your first trade — start with a small amount
5. Use limit orders to avoid taker fees — only taker orders pay fees on Polymarket

If you are a Chinese national living outside the mainland (Hong Kong, Macau, or abroad), the practical picture is very different, and Polymarket is far more accessible to you directly.
