1. Why Taiwan Blocks Coinbase and Kalshi
Taiwan blocks Coinbase and Kalshi from domestic access after a New Taipei court approved a request from the island's Criminal Investigation Bureau, which suspects both platforms of enabling illegal betting on the November 28 local elections. Users in Taiwan began reporting problems around October 14, 2026, and were redirected to a notice referring to the court order, about six weeks before voters go to the polls.
The action targets the websites of Coinbase, the largest US-listed crypto exchange, and Kalshi, a US-regulated prediction market where users trade contracts on the outcome of real-world events. It extends a policy that Taiwanese authorities have applied before: people may follow an election closely, but they may not stake money on its result.
For the crypto industry the episode is notable because it ties a mainstream exchange to the prediction-market business it has built through a partnership with Kalshi. A regulatory conflict in one jurisdiction over event contracts has now reached a platform that most users know as a place to buy and sell digital assets.
2. What Did the Court Authorize?
The New Taipei court granted the Criminal Investigation Bureau's request, which allowed the communications regulator and the internet registry to restrict access to the two sites from within Taiwan. The measures apply locally. They prevent people in Taiwan from reaching the websites but do not affect users in other countries.
The bureau's legal basis is the Public Officials Election and Recall Act. The law prohibits running gambling for profit on the outcome of an election or recall vote. The bureau says both platforms violated that provision by offering or facilitating wagers on Taiwan's upcoming local races.
Reports differ on the exact sequence of events. Access problems appeared around October 14, and the court authorization was reported shortly afterward. People who tried to open the sites saw a block page that cited the court orders, which made clear that the interruption was a deliberate legal measure and not a technical fault.
3. How Does Taiwan's Election Law Treat Betting?
Betting on elections is illegal in Taiwan, and the penalties differ depending on the role a person plays. Under the Public Officials Election and Recall Act, those who place bets can face up to six months in prison, while operators who run such wagering for profit can face up to five years. The structure reflects a view that organizing a market on an election is more serious than taking part in one.
The law was written long before blockchain-based and web-based prediction markets existed, yet its language about profit-oriented gambling tied to election results is broad enough to cover them. Authorities have shown a willingness to apply it to foreign platforms that Taiwanese residents can reach online, even though the companies are based abroad and may argue that their products are lawful where they are licensed.
That gap between where a platform is regulated and where its users sit is the central difficulty. A service can be fully compliant in its home country and still run into a local ban elsewhere, and a website block is one of the few tools a government has to enforce its own rules against an overseas operator.
4. What Reason Did the Authorities Give?
The Criminal Investigation Bureau described the online betting as a threat to the integrity of the electoral process. It also pointed to the risk of overseas interference, presenting the blocks as a step to head off outside influence before the vote. The bureau gave no further details about that concern, and the authorities have not alleged that Coinbase or Kalshi handled money from any specific foreign source.
The framing is significant. Rather than treating the matter only as consumer protection or gambling enforcement, officials placed prediction markets inside the topic of election security. A market in which participants bet on a candidate's chances can, in the view of regulators, create incentives to influence the outcome or distort perceptions of it, which is a concern separate from whether any individual bettor loses money.
This approach gives the government a stronger argument for acting quickly. Election-security measures often receive broad public backing, and tying the blocks to that goal puts the platforms in the position of defending a business model against a claim about democratic integrity.
5. How Do Website Blocks Work in Practice?
Blocking a website at the national level usually relies on cooperation from the bodies that run a country's internet infrastructure. In this case the communications regulator and the registry that manages domain-name services were authorized to restrict access, so that a request to open the sites from within Taiwan is either refused or redirected to a notice page. The approach is quick to apply and does not require the foreign company's consent.
These measures are rarely airtight. Users can sometimes reach blocked services through virtual private networks or through alternative access routes, and mobile applications may continue to work if they connect to servers that the order does not cover. For that reason authorities tend to pair technical blocks with criminal penalties for those who place bets, which is consistent with the six-month and five-year ranges in the election law.
The block is therefore best understood as a signal as much as a barrier. It tells platforms that their products are being watched during the campaign period, and it tells residents that using such services to wager on the vote carries legal risk.
6. What Is the Link Between Coinbase and Kalshi?
Coinbase offers prediction markets to its customers through a partnership with Kalshi, so contracts listed on Kalshi can be traded from within the exchange's interface. Kalshi lists contracts tied to elections, and these include markets on Taiwanese local races such as the Taipei mayoral contest. That overlap explains why a single action caught both companies.
Kalshi's position is that it does not permit trading in Taiwan. Coinbase acknowledged that some users were having trouble reaching its services and said it was looking into the problem. Reporting varies on whether the Coinbase mobile app remained reachable for some users after the web block took effect, which is common with this kind of restriction because websites, application servers and app-store distribution are controlled separately.
The distinction between a company's stated policy and the access its products actually provide is likely to remain a point of contention. A platform may bar users in a country in its terms, yet authorities can still conclude that residents were able to reach and trade its markets, which is the finding the bureau appears to have reached.
7. Is This Taiwan's First Move Against a Prediction Market?
It is not. Taiwan was among the first governments to block Polymarket, the crypto-based prediction platform, and it did so under the same election law. Police in Taiwan have also made arrests in connection with betting on a previous presidential election. The new action places Coinbase and Kalshi alongside Polymarket on the list of services that have been cut off from Taiwanese users.
The pattern suggests that officials are applying the law consistently, not making a one-off example of a single company. Each case rests on the same statute and the same argument, and each demonstrates a readiness to act against foreign services when an election is approaching.
Other countries have taken comparable steps. Regulators in several jurisdictions have restricted access to Polymarket, and Singapore's gambling regulator ordered local internet providers to block it, a move reported as following earlier action in Taiwan and France. Taken together, these measures show that governments treat election contracts differently from other event markets, even where they allow some forms of prediction trading.
8. What It Means for Prediction Markets and Crypto Exchanges
The block highlights a tension in the expansion of crypto exchanges beyond spot trading. Coinbase has been adding products, including prediction markets, that make it look more like a broad financial platform. That strategy works best in places where event contracts are regarded as financial instruments subject to market regulation. It faces obstacles wherever the same contracts are classified as gambling, a category with different rules, licenses and penalties.
Election contracts are the most sensitive part of the field. Supporters of prediction markets argue that they aggregate information well and can produce useful forecasts, while critics argue that they invite manipulation and put a price on democratic outcomes. Regulators who share the second view have little reason to distinguish between a dedicated prediction venue and a large exchange that distributes its contracts.
For companies, the practical lessons are geographic. Offering event contracts across borders requires attention to the local election law of each market, and a product that is legal in the United States can trigger criminal-law consequences in another country. Platforms may respond by restricting election markets by region or by removing certain contract types, though neither is certain.
9. What Happens Next?
The most immediate date is November 28, when Taiwan holds its local elections. The block is expected to remain in force at least through the campaign, and the authorities have given no indication that they plan to lift it before the vote. Whether it continues afterward will depend on how the platforms respond and on any further action by the court or the bureau.
Coinbase has said it is investigating the access problems, and further clarity about its mobile app and about how it intends to handle Taiwan-related contracts may follow. Kalshi's statement that it does not allow trading in Taiwan suggests it will argue that the underlying activity should not have been possible for local users.
Observers in the crypto and prediction-market industries will also watch whether other governments with strict election-betting rules take similar steps against mainstream exchanges. If they do, the regulatory risk around election contracts would extend well beyond dedicated prediction platforms to the large companies that distribute them.
