Polymarket is fully blocked in Cuba. Cuba sits on the US Treasury OFAC comprehensive sanctions list, and Polymarket applies its most restrictive status to the country: block-complete — no orders can be placed, and existing positions cannot be closed. This is a sanctions-driven block rather than an ordinary regional geoblock, and it means there is currently no supported way to use Polymarket from Cuba.

Current Status: Fully Blocked

Cuba is blocked on Polymarket. Unlike close-only countries, where existing accounts can unwind open positions, a blocked country offers zero access: no new trades, no closing trades, no deposits or withdrawals.

This status comes directly from US sanctions. Cuba is a target of the Cuban Assets Control Regulations (CACR), one of OFAC’s longest-running and most comprehensive sanctions programs. As a result, Polymarket — a US-connected platform — prohibits all activity for Cuban IP addresses and accounts. This is block-complete, not close-only: there is no path to trade or to close an existing position.

Sanctions Context

The US embargo on Cuba has been in effect for decades, administered by OFAC (the Office of Foreign Assets Control) under the Cuban Assets Control Regulations (31 CFR Part 515). These are comprehensive sanctions, which generally prohibit virtually all trade, financial, and other transactions between US persons and Cuba.

Because of this framework:

  • Polymarket blocks Cuba completely — the most restrictive status, reserved for OFAC-sanctioned countries (alongside Iran, North Korea, and Syria).
  • US-based crypto platforms and exchanges generally cannot onboard or serve Cuban residents.
  • US persons are, with limited exceptions, prohibited from engaging in most transactions with Cuba, including providing digital-asset services.

OFAC has also increasingly applied its sanctions framework to crypto — including designating crypto wallets and entities connected to sanctioned jurisdictions and expanding enforcement in digital assets.

Cuba’s Progressive Crypto Stance

Cuba’s economic situation and sanctions-driven need for alternatives have pushed the island in a relatively crypto-friendly direction:

  • In August 2021, Cuba’s central bank (Banco Central de Cuba) recognized and took steps to regulate cryptocurrencies, citing reasons of socioeconomic interest.
  • In April 2022, the central bank issued regulations requiring virtual asset service providers to obtain a license from the central bank.

Crypto adoption on the island has grown — reports in 2022 estimated roughly 100,000 Cubans using bitcoin — driven by mobile internet growth and the difficulty of using US-controlled financial rails under sanctions, including for remittances.

The Conflict with US Sanctions

Despite Cuba’s domestic openness, US OFAC sanctions take precedence for US-connected platforms. This tension is why:

  • Crypto activity in Cuba often relies on foreign, non-US platforms and peer-to-peer arrangements.
  • US-based platforms like Polymarket must block Cuba under US law.

For a Cuban resident, the practical effect is that the mainstream US crypto ecosystem — including Polymarket — is off-limits, while a parallel, higher-risk market of foreign platforms and P2P trading exists.

Deposit & Trading Status

There is no supported deposit or trading path for Polymarket from Cuba.

  • Polymarket does not allow Cuban users under US sanctions.
  • There is no verified local exchange offering a CUP-to-USDC on-ramp that connects to Polymarket.
  • Even if an on-ramp existed, the platform’s block-complete status for Cuba means deposits and trades would not be permitted.

Residents should be aware that attempting to access US-sanctioned, US-connected financial services from Cuba can carry legal risk under US and international sanctions frameworks.

Tax Considerations

Cuba has no established framework for taxing prediction-market or crypto trading profits, and the US sanctions overlay makes reporting largely theoretical for Cuban users.

More broadly, Cuba’s monetary system underwent a major currency unification in 2021, eliminating the convertible peso (CUC) and leaving the Cuban peso (CUP) as the single official currency. Any tax treatment of crypto gains in Cuba is evolving and should be reviewed with a local adviser — nothing specific is reliably verifiable today.

Getting Started

At this time there is no supported way to get started with Polymarket from Cuba:

  1. Understand the block — Cuba is block-complete (OFAC), the most restrictive Polymarket status.
  2. Be aware of sanctions — US OFAC sanctions prohibit US-connected platforms from serving Cuba.
  3. Consider legal risk — Attempting to route around the block carries potential sanctions exposure.

If you believe your situation falls under a permitted exception or you are a non-Cuba resident, review the Country Availability Checker and the Polymarket country guides for the latest status.

Frequently Asked Questions

Is Polymarket available in Cuba?
No. Polymarket fully blocks Cuba. Cuba is on the US Treasury OFAC comprehensive sanctions list, and Polymarket lists the country as blocked completely — no orders can be placed and existing positions cannot be closed. This is a sanctions-driven block, not an ordinary geoblock.
Why is Polymarket blocked in Cuba?
Cuba is subject to the US embargo administered by OFAC under the Cuban Assets Control Regulations (CACR). OFAC sanctions generally prohibit virtually all transactions by US persons and US-connected platforms with Cuba. Because a fully blocked country is not government geoblocking but platform compliance with US sanctions, Polymarket's block-complete status means no account activity at all.
Is 'blocked' the same as 'close-only' on Polymarket?
No. Close-only countries (accounts can close existing positions but not open new ones) are a different category. Cuba is 'blocked' — Polymarket's most restrictive status, applied to OFAC-sanctioned countries. Accounts tied to Cuba cannot trade, cannot deposit or withdraw, and existing positions cannot be closed.
Is cryptocurrency legal in Cuba?
Cuba's central bank (Banco Central de Cuba) has recognized and regulated cryptocurrency since 2021, and in 2022 issued rules requiring virtual asset service providers to obtain a central bank license. Crypto use on the island grew in part to work around US sanctions and for remittances. However, US sanctions mean most US-based crypto platforms and exchanges cannot onboard Cuban users.
Can I deposit on Polymarket from Cuba?
No. Because Polymarket blocks Cuba completely, there is no supported deposit or trading path. There is no verified local exchange offering a CUP-to-USDC on-ramp. Anyone in Cuba attempting access should understand that US OFAC sanctions prohibit US-connected platforms from serving Cuban users, and using them could carry legal risk.
