Polymarket is technically accessible in Solomon Islands — the platform does not geoblock Solomon Islands IP addresses. However, this Southwest Pacific nation faces significant practical barriers: limited banking, constrained internet access and essentially no local crypto on-ramps. Here’s an honest look at what using Polymarket from Solomon Islands involves.
Current Status: Accessible
The Solomon Islands is not on Polymarket’s geoblocked countries list, so the platform is technically available. The country uses the Solomon Islands dollar (SBD) and has a small financial sector.
The Central Bank of Solomon Islands (CBSI) has issued public cautions about the risks of cryptocurrency. These are investor warnings rather than an outright ban — there is no prohibited trading or enforcement targeted at individual prediction-market users, but the official posture is cautious.
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 Solomon Islands Polymarket users. The main obstacle is practical access, not legal prohibition.
The Legal Landscape
Central Bank of Solomon Islands (CBSI)
The Central Bank of Solomon Islands (CBSI) regulates the monetary and financial system and has warned about the risks of volatile cryptocurrencies. Its stance is cautionary, but cryptocurrency is not banned for personal holding, and no dedicated framework governs individual use of overseas platforms.
Gambling and Prediction Markets
The Solomon Islands does not have a specific legal framework that addresses online prediction markets. Prediction markets operate in an unregulated gap. There is no explicit ban and no specific enforcement action against users, but the activity is legally undefined.
The Practical Constraint
The binding constraint is infrastructure: limited banking, restricted card/internet access and no domestic exchange. Users must work through international rails.
How to Deposit from Solomon Islands
Direct on-ramps are effectively unavailable, so the practical route is an international exchange funded with Solomon Islands dollars (SBD).
Step 1: Buy USDC on a Global Exchange
| Exchange | SBD Support | Card Payments | P2P | Notes |
|---|---|---|---|---|
| Binance | No (P2P/card) | Yes | Yes | Global leader; buy USDC via card or P2P |
| Bybit | No | Yes | Yes | Card purchase supported |
| OKX | No | Yes | Yes | Low fees; card or P2P purchase |
| KuCoin | No | Yes | Yes | Widely used globally; card purchase via partner |
Deposit Methods Explained
International Cards: If you have a Visa or Mastercard that works internationally, you can try to buy USDC or USDT directly on a major exchange. Card approval and availability can be uncertain from remote Pacific locations.
P2P (Peer-to-Peer) Trading: P2P trading lets you buy USDC from other users using bank transfer funded in SBD or a major currency — practical where card routing fails.
Fund from an existing account: If you already hold funds or crypto elsewhere, sending them to your destination exchange before moving USDC on to Polymarket is often the least friction path.
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
The Solomon Islands’ tax treatment of crypto is fact-dependent and not explicitly defined.
Income Tax
The Solomon Islands imposes income tax on residents. There is no dedicated crypto tax, and the treatment of crypto gains is not clearly defined by statute, making it uncertain for active traders.
What to Consider
- Keep dated records of all deposits, trades, withdrawals, and SBD/USD conversion rates.
- Because the crypto treatment is not explicitly defined, consult a tax adviser if you trade at scale.
- There is no dedicated crypto surcharge — standard tax principles apply.
