Online gambling is illegal in Thailand. The Gambling Act B.E. 2478 (1935) bans nearly all betting; the only legal exceptions are the state lottery run by the Government Lottery Office (GLO) and licensed on-course horse-race betting in Bangkok. Online casinos and sportsbooks - including offshore sites that accept Thai players - are unlawful, and the authorities routinely block gambling websites. A high-profile ‘Entertainment Complex’ casino bill was proposed in 2025 but was withdrawn amid political turmoil and, as of 2026, has not become law. Treat any site claiming to be a ‘licensed Thai online casino’ with extreme caution.

Thailand is one of Asia’s most restrictive gambling jurisdictions. The 1935 Gambling Act prohibits casinos, slot machines, card games for money and most betting, and the Playing Cards Act even limits how many playing cards a person may own without permission. There is no licence you can obtain to legally run or use an online casino in Thailand today.

The two main carve-outs are the twice-monthly GLO lottery (drawn on the 1st and 16th) and betting on horse racing at the approved on-course totalisator. Everything else - football betting, online slots, poker sites, crypto prediction markets - is illegal, whether the operator is based in Thailand or offshore.

Is There A Regulator Or Licensing Regime?

There is no dedicated online-gambling regulator. Enforcement of the Gambling Act sits with the Royal Thai Police and the Ministry of Interior, and the Ministry of Digital Economy and Society (MDES) blocks gambling websites, while the GLO administers the lottery. The much-discussed Entertainment Complex Bill would, if passed, create a licensing regime for a small number of integrated casino resorts (reportedly up to three complexes with a proposed 17% gross-gaming-revenue tax), but it was withdrawn in 2025 after mass protests and a coalition crisis and rejected by a Senate committee, and is not in force. Reports in 2026 suggest a revised version may return to parliament, but nothing has been enacted.

Licensed vs Offshore Operators

TypeStatus in Thailand
GLO state lotteryLegal
Licensed on-course horse-race bettingLegal
Thai-based online casino/sportsbookIllegal (none licensed)
Offshore online casino/sportsbook targeting ThaisIllegal; sites blocked
Crypto casinos / prediction marketsTreated as illegal gambling

Many Thais still access offshore sites or travel to border casinos (for example Poipet in Cambodia), but this carries legal and financial risk. Offshore operators are not accountable to any Thai authority, so players have no local recourse if funds are withheld.

Payments Locals Actually Use

Because the activity is illegal, there is no official payment rail. In practice, everyday Thai payments run through PromptPay (the national instant bank-transfer system), mobile banking apps and cash. Offshore gambling sites often ask for bank transfers, e-wallets or cryptocurrency - all of which expose users to anti-money-laundering scrutiny and account-freezing risk. Thai banks and police have increasingly frozen accounts linked to suspected gambling flows.

Cryptocurrency itself is legal in Thailand as a regulated digital asset overseen by the SEC, and trading is permitted through locally licensed exchanges. However, it is not legal tender, and the Bank of Thailand restricts using digital assets to pay for goods and services. Crucially, using crypto to gamble does not make gambling legal: authorities have classed crypto betting platforms such as Polymarket as illegal gambling under the 1935 Act and moved against them - Polymarket was placed on close-only status for Thai users in 2025. Crypto gambling combines two areas of legal exposure at once.

Tax On Winnings

For the legal state lottery, a 0.5% stamp duty is deducted from prizes (1% for the rarer charity-lottery tickets); there is no separate personal income tax on the prize in Thailand. Because all other gambling is illegal, there is no legitimate tax framework for it - and illicit winnings can attract law-enforcement and money-laundering attention rather than a tax bill.

Safer Gambling & Help

If gambling is causing harm, support is available. Call 1323, the Department of Mental Health hotline - free, confidential and 24/7, including for gambling-related distress. In a crisis, dial 1669 (medical emergency) or 191 (police).
