Country-by-country rules, regulator actions and sources for Polymarket and Kalshi.
This is not legal advice, and we don't say whether trading is legal for you in Vietnam. We report what each platform's published rules say about Vietnam and the public regulator, court and police actions we could source, each with a date. Those rules change fast, so check the platform's current terms and the law in Vietnam before doing anything. ‘Not listed’ only means a platform's own list doesn't name Vietnam; it doesn't mean trading there is permitted.
Status under each platform's own published rules, and the most recent public action we could source, as of 2026-09-24.

This page keeps two things apart for Vietnam: what each platform's own published rules say, and what regulators, courts and police in Vietnam have publicly done. A platform's list is its own policy and a government order is the government's, so a country can be on one and not the other.
The status labels are the same as in the main table. Restricted means the platform's own list blocks trading from Vietnam. Close-only means existing users there can close positions but can't open new ones. Some regions means only named regions are restricted. Separate product means residents use a different, separately regulated product, as US residents do with the Polymarket US app. Not listed means the platform's published list doesn't name Vietnam; that is not the same as permitted, and a regulator may still block the site.
Polymarket publishes two official lists that don't fully match: its Help Center page (updated August 14, 2026) and its developer docs (undated). We follow the dated Help Center list and say where the developer docs differ. Kalshi statuses follow its Member Agreement as fetched on September 24, 2026; the agreement itself is undated.
Each action shows the authority as it names itself, what it did, the platform it concerns and the date: the date of the action where it was published, otherwise the date it was first reported. Every entry is marked Official, Platform document or Secondary report. Where only secondary reporting exists, we say ‘reported by’ and name the outlet; where official sources conflict, we report both.
‘No public action found’ means our searches found none, not that none exists. Nothing on this page says whether trading is legal for you: for that, check the platforms' current terms and the law in Vietnam.
Polymarket's Help Center page on geographic restrictions, updated August 14, 2026, lists 39 blocked countries and a separate close-only group; Vietnam is on neither. Its undated developer geoblock documentation doesn't name Vietnam in any tier either, so the two Polymarket lists agree. Under this site's labels Vietnam is Not listed for Polymarket. That describes Polymarket's own policy only: it doesn't mean trading from Vietnam is permitted, and we found no Polymarket blog post, help article or notice that mentions Vietnam.
In practice the restriction reported in Vietnam comes from the government, not from Polymarket. According to Blockintosh (January 30, 2026), polymarket.com now returns a Ministry of Public Security warning page instead of the site for most Vietnamese IP addresses, the same interstitial mechanism the Ministry uses for gambling and piracy sites; the reports don't say whether the block works at DNS or IP level, and we have not confirmed whether it was still in place on September 26, 2026. No app-store removal has been reported. Two commercial affiliate pages, updated March 10 and March 24, 2026, claimed the site was ‘accessible, no IP blocking’ from Vietnam; they cite no sources and have an interest in the answer, so we record the conflict and don't rely on them.
Vietnam is not on the list of 55 Restricted Jurisdictions in Section VI of Kalshi's Member Agreement (undated; fetched September 24, 2026), and it wasn't on the lists in Kalshi's Exchange Notices of October 23 and November 4, 2025. Under this site's labels Vietnam is Not listed for Kalshi. Kalshi's help center (updated March 20, 2026) says trading from outside the United States is subject to the Member Agreement. We found no Kalshi blog post or notice naming Vietnam, and no Vietnamese regulator, court or police action naming Kalshi, in Vietnamese or English, as of September 26, 2026. ‘Not listed’ describes Kalshi's contract only and says nothing about Vietnamese law.
Vietnam has no regulator dedicated to prediction markets. Online gambling is policed by the Ministry of Public Security (Bộ Công an) through its Department of Cybersecurity and High-Tech Crime Prevention (Cục An ninh mạng và Phòng, chống tội phạm sử dụng công nghệ cao, A05), which is the body Vietnamese crypto media name as having blocked polymarket.com. Crypto-asset trading is overseen by the Ministry of Finance and the State Securities Commission (SSC), which run the licensed-exchange pilot under Resolution 05/2025/NQ-CP; SSC deputy head Tô Trần Hòa said in March 2026 that ‘unpermitted platforms will not be allowed to provide services in Vietnam’ (reported by The Investor, March 26, 2026), a statement about crypto platforms generally, not about prediction markets. Legal betting is confined to licensed horse racing, greyhound racing and international football under a 2017 decree. The gambling offences are Article 321 (gambling) and Article 322 (organising gambling) of the 2015 Criminal Code as amended in 2017.
January 30, 2026 (secondary reports): Blockintosh reported that access to polymarket.com had been cut for most Vietnamese IP addresses and that visitors now see a Ministry of Public Security warning that the site ‘has signs of gambling activity’ and that accessing it violates Vietnamese law; Coin68 and other Vietnamese crypto outlets posted the same report on X that day. Blockintosh cites Articles 321 and 322 of the Criminal Code as the basis. We searched the Ministry's own sites (bocongan.gov.vn, cand.com.vn, khonggianmang.vn) and found no press release, gazette entry or blocklist entry, and the mainstream outlets VnExpress and Tuổi Trẻ carried no article on it, so this page treats the block as a secondary report and it appears as Blocking order in the timeline below. The action targets the platform's website; no proceeding against Polymarket as a company, no court order and no court challenge have been reported, and we found no report of the block being lifted.
We found no Vietnamese court ruling on prediction markets and no action by the Ministry of Finance, the State Securities Commission, the State Bank of Vietnam or the National Election Council naming Polymarket or Kalshi. Our searches in Vietnamese and English through September 26, 2026 found no other public action; that means we found none, not that none exists.
The entries below are rendered from the same dated data as the main country table, newest first. Each row shows the date, the authority as it names itself, the type of action, the platform it concerns and the source with its type.
| Date | Authority | Action | Platform | Source |

Public regulator, court and police actions concerning Polymarket and Kalshi in Vietnam, as of 2026-09-24. Not legal advice.
This section reports what the law and the authorities in Vietnam have said about people who take part in these markets, and any enforcement against users that has been made public. It describes; it doesn't advise.
We found no statement by a Vietnamese authority about penalties for Polymarket or Kalshi users specifically, and we found no prosecution, arrest or tax-office statement tied to either platform. The general rules for participants, as summarised on June 19, 2026 by vietnam.vn, an outlet linked to the Ministry of Public Security, in an article about football betting: small-stake betting is an administrative offence under Article 36(2)(c) of Decree 282/2025/NĐ-CP, with a fine of 1–2 million VND; from 5 million VND in stakes, Article 321 of the Criminal Code applies, with a fine of 20–100 million VND, non-custodial reform of up to 3 years or 6 months to 3 years' imprisonment, rising to 3–7 years where the offence involves ‘using the internet’ or stakes of 50 million VND or more. Whether those provisions apply to a prediction-market position has not been stated by any court or authority we could find.
A separate rule concerns the crypto-assets used to fund such positions. Decree 284/2026, in force since September 1, 2026, fines individuals 30–50 million VND (70–100 million VND in the higher tier) for trading crypto-assets outside providers licensed by the Ministry of Finance, and unlicensed providers 180–200 million VND (reported by VietnamPlus, the state news agency, July 20, 2026). No source we found says whether a USDC-funded prediction market counts as an unlicensed crypto platform under that decree. We found no bank or licensed-exchange policy naming Polymarket or Kalshi.
Vietnam was the subject of a large political market shortly before the reported block. Polymarket's event ‘Vietnam Communist Party General Secretary Election’ opened on January 14, 2026 and resolved on January 25, 2026 with about US$11.8 million in volume (Polymarket's own self-published figure) and Tô Lâm at 100%, around the Communist Party's 14th National Congress of January 19–23, 2026, at which he was re-elected General Secretary on January 23. The block was reported five days after the market resolved. No source we found connects the two, so we present this as timing only. Polymarket also runs a ‘Next President of Vietnam’ event. Searches such as ‘polymarket tổng bí thư việt nam’ (Polymarket Vietnam general secretary) are among the most common Vietnamese queries about the platform.
Vietnam is building a licensed domestic crypto framework: Resolution 05/2025/NQ-CP set up a pilot for licensed domestic exchanges, and the State Securities Commission said in March 2026 that all Vietnamese investors will have to trade on licensed domestic venues once the first is live (reported by The Investor, March 26, 2026). None of those statements mentions prediction markets or either platform.
PolyKal is a read-only research site, and it does not restrict access by country, including from Vietnam. Its public pages, including prices on both platforms, order-book depth, after-fee cost comparisons, the fee calculator, and large-trade and whale data, need no account. You don't need a VPN to use them.
Viewing public market data is not trading. PolyKal doesn't place orders, hold funds or give access to trading on either platform, and a restriction on Polymarket or Kalshi in Vietnam still applies to trading there. Polymarket's help center says that using a VPN to get around its restrictions violates its Terms of Use, and Kalshi's Member Agreement excludes people in its restricted jurisdictions; getting around a block can also break local law. PolyKal doesn't help anyone get around them.
Start with the compare page, the fee calculator or large trades, or read how Polymarket works and how Kalshi works.
Vietnam is one of 27 countries, plus the United States, that PolyKal tracks. The full availability table shows every country's status under each platform's rules and its regulator actions side by side, with the same dates and sources as this page, and its change log lists every edit we make.
Every entry is re-checked at least once a quarter, and sooner when a platform or regulator announces a change. The next scheduled full re-check is shown in the sidebar.
Vietnamese crypto outlets Blockintosh and Coin68 reported on January 30, 2026 that the Ministry of Public Security's cybersecurity department (A05) had blocked polymarket.com for most Vietnamese IP addresses and replaced it with a warning that the site ‘has signs of gambling activity’. We found no official notice from the Ministry, no court order and no report of the block being lifted, so the action is recorded as a secondary report. Polymarket's own lists don't restrict Vietnam, which means the restriction, as reported, is the government's, not the platform's.
We found no published Vietnamese court or regulator ruling on it, and we don't decide it for you. What the record shows: legal betting in Vietnam is limited to licensed horse racing, greyhound racing and international football; gambling is an offence under Articles 321 and 322 of the Criminal Code, with administrative fines for small stakes under Decree 282/2025/NĐ-CP; and the Ministry of Public Security's reported warning page (January 30, 2026) says the site has signs of gambling activity and that accessing it violates Vietnamese law. Neither Polymarket nor Kalshi lists Vietnam as restricted, which is a fact about their rules, not about the law. Check the current law and the platforms' current terms before doing anything.
Kalshi's Member Agreement (fetched September 24, 2026) doesn't list Vietnam as a restricted jurisdiction, and its help center says international trading is subject to that agreement. That is Kalshi's contract, not a statement about Vietnamese law: the gambling provisions and the reported Ministry of Public Security position described on this page don't distinguish between platforms, and we found no Vietnamese authority that has addressed Kalshi by name.
The stated reason, as reported by Blockintosh on January 30, 2026, is that the Ministry of Public Security's warning page calls the site one with ‘signs of gambling activity’; Blockintosh cites Articles 321 and 322 of the Criminal Code. The Ministry has published no explanation we could find. The block was reported five days after Polymarket's ‘Vietnam Communist Party General Secretary Election’ market, with about US$11.8 million in volume by Polymarket's own count, resolved on January 25, 2026; no source connects the two, so that is timing, not a stated cause.
Yes, on PolyKal. Its pages load from Vietnam without an account and show prices, order-book depth and after-fee comparisons for both platforms, including Polymarket's Vietnam markets. Viewing data is not trading: PolyKal doesn't place orders or hold funds, and the reported block on polymarket.com and the legal positions described on this page still apply to trading.
No. Polymarket's help center says that using a VPN to get around its restrictions violates its Terms of Use, and Kalshi's Member Agreement excludes people in its restricted jurisdictions. Getting around a block can also break local law. You don't need a VPN to research these markets: PolyKal's prices, order books and fee calculator don't require one.
We re-check every country page at least once a quarter, and sooner when a platform or regulator announces a change; each rule and action on the page shows its own date and source. If you spot something out of date for Vietnam, email [email protected] with a link to the new rule or order.
Every statement on this page rests on the sources below. Platform rules were checked against Polymarket's and Kalshi's own pages on September 24, 2026; regulator, court and police actions were checked against the sources listed on September 24–26, 2026. Each source is marked as official, a platform document or a secondary report. Where only secondary reporting was available, we cite it and say so; where official sources conflict, we report both.
