The Short Version

Taiwan is the one jurisdiction in the Chinese-speaking world where a Polymarket user has actually been criminally charged - by name, in a published case. Polymarket itself placed Taiwan in close-only mode at the protocol level: existing positions can be closed, but no new trades or deposits are accepted. And Taiwanese law criminalizes betting on election outcomes specifically, with the June 2024 Chen case as the canonical precedent. This page lays out the facts. It does not promote any election market to Taiwan readers, because that is precisely the conduct that was prosecuted.

The Statute That Matters

Article 90-1 of the President and Vice President Election and Recall Act - with parallel provisions in the Civil Servants Election and Recall Act - criminalizes betting on election or recall outcomes. The penalty reaches six months of imprisonment, detention, or fines, and the provision covers online conduct. This is not a dormant law: Taiwanese prosecutors used it against online election bettors during the 2024 presidential cycle.

The Chen Case, June 2024

The canonical precedent names Polymarket directly. A defendant surnamed Chen placed roughly 472 USDC on Ko Wen-je of the TPP winning the presidency, plus 60 USDC on DPP legislative seat outcomes, through Polymarket. The Shilin District Prosecutors Office charged him under the President and Vice President Election and Recall Act. The outcome was deferred prosecution for one year and a NT$30,000 fine - roughly US$1,000. First-offender leniency softened the result, but the indictment was real, and Taiwan News had already reported multiple arrests for the same conduct in January 2024.

Polymarket's Posture

Taiwan is listed as close-only in Polymarket's published documentation - both the geoblock API reference and the help-center geographic-restrictions page. Taiwanese users with legacy positions can close them; they cannot open new ones or deposit. This is a protocol-level enforcement, not a suggestion, and Polymarket's terms of service prohibit circumventing geographic restrictions.

The Crypto Side

For completeness: holding or spot-trading crypto as an individual is not criminalized in Taiwan. The FSC's VASP registration regime, drafted in March 2025, targets operators - unregistered platforms face up to two years of imprisonment or fines up to NT$5 million. Gains are generally treated as income for tax purposes. None of this changes the election-betting analysis above, which is a gambling-law matter, not a crypto-law matter.

What This Means for Readers

Our Taiwan-facing coverage is news and analysis about a US platform, including how US politics markets price events that matter to Taiwanese readers. It is not an invitation to trade on Taiwanese elections - which Polymarket's close-only status prevents anyway, and which Taiwanese law actively prosecutes. Diaspora readers in open jurisdictions should consult the country availability guide for their local status.
