Polymarket is accessible in Guinea-Bissau — the platform does not geoblock Guinea-Bissau IP addresses. This small West African nation uses mobile money and the West African CFA franc (XOF), though local on-ramps are limited. Here’s what Guinea-Bissau users need to know about using Polymarket.
Current Status: Accessible
Guinea-Bissau is not on Polymarket’s geoblocked countries list. The platform is accessible from local IP addresses. Users can sign up, deposit, and trade on all available markets.
The country uses the West African CFA franc (XOF), issued by the BCEAO. Banking infrastructure is limited, so mobile money and peer-to-peer trading are the most practical routes into crypto. Note that Guinea-Bissau is distinct from Guinea (Conakry), which is a separate country.
The legal landscape for prediction markets sits in a grey area: there is no specific law on crypto or prediction markets, and no record of enforcement against users.
The Legal Landscape
BCEAO and the WAEMU Framework
Guinea-Bissau’s monetary framework is set regionally by the BCEAO. The BCEAO has warned about crypto risks but has not established a framework regulating individuals’ private holdings or overseas platforms.
Gambling and Prediction Markets
Guinea-Bissau does not have a specific legal framework that addresses online prediction markets. Prediction markets operate in an undefined gap. There is no explicit ban and no enforcement targeting users, but the activity is legally undefined.
How to Deposit from Guinea-Bissau
Banking infrastructure is limited, so P2P trading and mobile money are the most practical routes.
Step 1: Buy USDC on a Global Exchange
| Exchange | XOF Support | Mobile Money | P2P | Notes |
|---|---|---|---|---|
| Binance | Yes (P2P) | Yes | Yes | Global leader; P2P on-ramp |
| Bybit | Partial (P2P) | Partial | Yes | Card or P2P purchase |
| OKX | No | No | Yes | Low fees; P2P available |
| KuCoin | No | No | Yes | Widely used globally |
Deposit Methods Explained
P2P (Peer-to-Peer) Trading and Mobile Money: Load a mobile-money wallet, then use peer-to-peer trading on an exchange to buy USDC or USDT in CFA francs (XOF). This is the most practical route given limited banking.
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
Guinea-Bissau’s treatment of crypto is fact-dependent and not explicitly defined.
Income Tax
Guinea-Bissau levies income tax on residents. There is no dedicated crypto tax, and the classification of crypto gains is not clearly defined, so treatment can be uncertain.
What to Consider
- Keep dated records of all deposits, trades, withdrawals, and XOF/USD conversion rates.
- Because the crypto treatment is not explicitly defined, consult a tax adviser if you trade at scale.
