The History of Gambling in Argentina
Argentina has no national gambling law, and that absence is the single most important fact about the market. Under Article 121 of the Constitución Nacional (National Constitution), the power to regulate games of chance was never delegated to the federal government, so each of Argentina’s 24 provincial jurisdictions writes and enforces its own rules, licenses its own operators, and taxes its own casinos, bingo halls and lotteries. The result, confirmed repeatedly by the Corte Suprema de Justicia de la Nación (CSJN, the national Supreme Court), is a country with one currency and one national football team but roughly two dozen separate gambling regimes. A licence issued in the City of Buenos Aires authorises nothing in the Province of Buenos Aires, let alone in Córdoba or Salta. This piece traces how that fragmented system came to be, from colonial-era charity draws to the online licensing wave of the 2020s.
A provincial game: the constitutional starting point
Article 121 of the Constitución Nacional states that “the provinces retain all power not delegated by this Constitution to the federal government, and whatever they expressly reserved through special pacts at the time of their incorporation.” Gambling regulation was never among the powers Article 75 hands to the national Congress, so it falls inside that reserved provincial sphere — and the CSJN has said so repeatedly. In 1869, in Empresa Plaza de Toros c/ Gobierno de Bs. As. (Fallos 7:150), the Court held that provincial police power over public morality and safety belongs to local governments. In 1903 (Fallos 98:156) it confirmed that a national gambling ban could validly apply only to the Capital Federal and the national territories, not the provinces. The most-cited modern precedent, Dándolo, Esperanza Patricia s/ infracción decreto-ley 6618/57 (1999, Fallos 322:1142), states flatly that “matters relating to games of chance — and their possible non-criminal infractions — are not a matter of federal character.”
The practical consequence: the national government cannot license an operator, set a national minimum age, or force a province to open or close its market. What national law does do is narrower — national taxes on winnings and betting turnover, anti-money-laundering obligations under the Unidad de Información Financiera (UIF), and, until 2018, direct operation of the lottery and casinos of the Capital Federal through a state company. Everything else — whether a casino may exist, who may run it, whether online betting is legal — has always been a provincial call.
Colonial charity draws and the birth of a national lottery
Lotteries in the Río de la Plata region predate the Argentine state itself, running informally as charitable raffles tied to hospitals, churches and colonial welfare works. The institution that gave the modern industry its shape is the Lotería de Beneficencia Nacional (National Charity Lottery), created by Ley 3.313, sanctioned on 30 October 1895. Per the historian Ana Cecchi’s peer-reviewed study of the institution, the law guaranteed funding for charitable works in the Capital and the provinces: of ticket-sale revenue, 75% (reduced to 70% by Ley 4.953 of 1906) was returned to the public as prizes, and of the remaining net proceeds, 60% funded hospitals and asylums in the Capital Federal while 40% was split among equivalent provincial institutions. The Lotería was folded into the Ministerio de Relaciones Exteriores y Culto from 1901 and sold tickets through licensed agencieros — 198 of them, controlling 2,200 decenas (ticket blocks) in 1895, concentrated in the Capital Federal.
For decades the Lotería de Beneficencia Nacional was the only legal game in the country: Ley 4.097 of 6 August 1902 banned all other games of chance and any unauthorised lottery in the Capital and national territories, empowering police to raid cockfights, roulette and card betting. That framework was reinforced by Ley 12.660 (1940) and, later, Decreto-Ley 6.618/57, which restated the prohibition in the Capital and Tierra del Fuego and defined a “casa de juego” (gambling house) broadly enough to catch any venue where banned games habitually took place. Outside this national-territory prohibition, provinces were already free to run and license their own games under their own police powers — the constitutional logic that would define the market for the next century.
Quiniela: Argentina’s own numbers game
Quiniela — a numbers-betting game usually played on the last digits of a lottery draw — grew up alongside the official lottery rather than inside it. Its clandestine origins date to around 1900 in Rosario and Buenos Aires, carried by Italian and Spanish immigration; bettors wagered on the final one or two digits of the daily Lotería de Beneficencia Nacional draw, entirely outside state authorisation. The word is generally traced to the Latin quintus (“fifth”), a nod to the five-digit lottery extract the game was built around. Because it began as an illegal, street-level bet run through neighbourhood operators, quiniela became deeply culturally embedded — documented by writers such as Roberto Arlt in his 1920s Aguafuertes Porteñas newspaper columns — long before provinces absorbed it into their own official lottery structures during the twentieth century. Today every province runs its own quiniela variant (Quiniela de la Ciudad, Quiniela de Santa Fe, and so on) as a core product of its lottery institute — a legacy of a game that started as an unauthorised bet on a government draw.
The turf: hipódromos and the arrival of slot halls
Horse racing has been licensed, taxed gambling in Argentina since the nineteenth century. The Hipódromo Argentino de Palermo, in Buenos Aires, opened on 7 May 1876 and quickly became — in the words of the press marking its 150th anniversary in 2026 — “the cathedral of the turf,” a rare case where racing drew a genuinely mass, working-class public rather than remaining an elite pastime. Racetrack betting sat alongside the Lotería de Beneficencia Nacional as one of the few gambling forms the state organised and taxed rather than suppressed, and it was folded into the same national machinery when the institution was renamed Lotería de Beneficencia Nacional y Casinos and formalised by Ley 18.226 (sanctioned 27 May 1969).
The racetracks were reshaped by two later developments. In 1992 the Hipódromo de Palermo was handed to a private concessionaire, H.A.P.S.A., under a concession running until 2017 — an early instance of the private-concession model later used across provincial casino and bingo regulation. In 2002, slot-machine halls (salas de tragamonedas) were introduced at the track, adding an electronic-gaming revenue stream to a venue whose core business had been pari-mutuel racing bets for over a century, a model soon replicated at provincial hipódromos nationwide.
The golden age of state casinos: Mar del Plata and the Atlantic coast
Argentina’s most iconic casino building, the Casino Central of Mar del Plata, is a product of 1930s provincial tourism policy, not national law. Buenos Aires Province governor Manuel Fresco granted the Unión Kursaal Argentina company a concession in 1938 to build and run gaming rooms in Mar del Plata, Miramar and Necochea; in exchange the company financed the Casino, the Gran Hotel Provincial and the Rambla Bristol promenade, all designed by architect Alejandro Bustillo and built between 15 July 1938 and the Casino’s inauguration on 22 December 1939. The complex quickly became the centrepiece of Mar del Plata’s identity as Argentina’s premier seaside resort.
That private-concession model did not last. From 1944, under Decreto Nº 31.090/44, the national government took the seaside gaming rooms under direct state administration, ending the Fresco-era concessions and folding Mar del Plata’s Casino into the same national umbrella that ran the Lotería de Beneficencia Nacional — a shift academic accounts of the period link to the broader nationalisation drive of the 1940s, and to the casino’s later role, alongside the nationalised hipódromos, as an unusual state revenue source during the Peronist years. Provincial and national control of the coastal casinos swung back and forth for the rest of the century, but the pattern set here — grand public buildings, tourism-linked concessions, revenue earmarked for social purposes — shaped how every subsequent government approached casino policy.
National consolidation, then handover: 1969 to the 1990s
The national institution reached its most codified form with Ley 18.226 (1969), naming the entity “Lotería de Beneficencia Nacional y Casinos” with explicit authority over the national lottery, casinos and gaming rooms, funded through ticket sales with fixed percentages earmarked for prizes, social assistance, health and sport. Ley 22.868 (1983) simplified the name to “Lotería Nacional,” and Decreto 598/90 converted it into Lotería Nacional Sociedad del Estado, a state-owned company, amid the Menem-era public-administration modernisation.
The more consequential shift of that decade was territorial rather than corporate: through the 1990s the provinces progressively reclaimed direct administration of the casinos on their own soil. In Buenos Aires Province, a convention signed 10 September 1992 between the newly created Instituto Provincial de Lotería y Casinos (IPLyC) and Lotería Nacional Sociedad del Estado — approved by provincial Decreto 327/93 — saw the province resume administration of its own casinos, with the last transfers completed by 1995. Other provinces followed, each building its own lottery-and-casino institute: Mendoza’s Instituto Provincial de Juegos y Casinos (Ley 6.362, 1995), Misiones’s IPLyC (converted to a sociedad del estado in 1999), Neuquén’s IJAN, Corrientes’s Instituto de Lotería y Casinos. The 1994 constitutional reform reinforced the trend: Buenos Aires Province’s constitution (Article 37) reserves “as a right not delegated to the Federal State, the administration and operation of all casinos and gaming rooms” and bars privatising the state banking function, while the Ciudad Autónoma de Buenos Aires’s 1996 constitution (Articles 9, 50 and 104) makes the same claim once the Capital gained autonomous city status.
Bingo: Buenos Aires Province’s contested network
Bingo halls became one of the largest employers in the provincial gambling sector from the 1990s onward, run through private concessionaires licensed by the IPLyC in Buenos Aires Province. By the early 2020s the province’s roughly 33 bingo halls together employed an estimated 25,000 people. The network has also been Argentina’s most politically contested piece of gambling infrastructure: in Buenos Aires City, the five municipal bingo halls (Lavalle, Congreso, Caballito, Flores and Belgrano) were wound down between 2016 and 2020 after their contracts lapsed, despite union efforts to protect roughly 500 jobs through court injunctions. In the province, COVID-19 closed every bingo hall for roughly nine months in 2020 and three more in 2021, and in 2023 the IPLyC abruptly shut 13 halls — all licensed to a single concessionaire, Codere — while comparable halls run by other operators stayed open, a decision unions and industry groups publicly called politically selective rather than neutral regulation. No comprehensive law has ever proposed shutting the network outright; it has repeatedly been narrowed through licensing and enforcement decisions instead.
The online licensing wave, 2018 onward
Online gambling arrived exactly the way land-based gambling had: province by province, with no coordinating national framework. The City of Buenos Aires moved first. Lotería de la Ciudad de Buenos Aires S.E. (LOTBA), created by city Ley 5.785 (December 2016), took over the Capital’s gambling regulation from the national Lotería under a 2016 inter-institutional agreement ratified by national Decreto 138/2017; LOTBA’s board then created online games of chance and sports betting by Resolución 321/2018 (27 November 2018), followed by licensing and age-verification rules in Resolución 80/2019. The national government completed its side of the handover with Decreto 95/2018, which placed Lotería Nacional S.E. into liquidation and repealed Ley 18.226 and Ley 25.295 at national level — formally ending direct national operation of any lottery or casino.
Buenos Aires Province followed within months: Ley 15.079 (sanctioned 3 December 2018) created a framework for “juego on line,” and Decreto 181/2019 (25 March 2019) put the IPLyC’s licensing regime into effect alongside Ley 15.131, a self-exclusion registry for compulsive gambling. From 2020 the wave spread further: Mendoza regulated online betting by Ley 9.267 (October 2020); Córdoba, Santa Fe, Misiones and Tucumán initially authorised it through pandemic-era executive decrees before converting those into standing law — Córdoba’s Ley 10.793 (December 2021) ratified nine such decrees, and Santa Fe’s Ley 14.235 (December 2023) replaced its own Decreto 998/20. Neuquén’s IJAN (created by Ley 2.751 in 2010) is usually cited as the earliest online-betting authority, authorising online casino and sports betting from 2012. By industry counts current in 2025–2026, roughly 20 of Argentina’s 24 jurisdictions regulate online gambling in some operative form.
Every one of these licences is strictly territorial: a platform authorised by LOTBA has no standing in the Province of Buenos Aires, and a Córdoba licence confers no rights in Mendoza. Argentina’s “.bet.ar” internet domain zone, opened by a 2019 resolution of the national domain registry, exists to signal which sites are authorised by some Argentine jurisdiction — not that they are authorised everywhere.

Trade-press tallies from 2025–2026 also count Catamarca, Chaco, Chubut, Formosa, La Pampa, La Rioja, Río Negro, San Luis and Santa Cruz among the provinces with an operative online regime, and describe San Juan’s regulation as approved but not yet fully implemented; this piece does not tabulate exact start years for those jurisdictions because sourcing for precise dates was not conclusive at the time of writing.
Provinces still closed to online gambling
As of 2026, Salta, Santiago del Estero and Tierra del Fuego remain without an operative online-gambling licensing framework. This is not the same as a ban: there is simply no mechanism to authorise or supervise online operators, leaving residents to access offshore platforms with no local licence, age or identity verification, responsible-gambling tooling, or domestic authority to complain to. Commentary describes this as a regulatory vacuum rather than a prohibition — distinct from the hard bans some provinces briefly imposed on land-based gambling (San Luis’s Ley 4.183 of 1967 outright prohibited casino gambling, subject only to a narrow, precarious exception).
Advertising, minors and the 2023–2026 legislative battle
Because gambling regulation is provincial, national law has never imposed a single advertising or minimum-age standard on operators. What national legislators have repeatedly tried, without yet passing a comprehensive statute, is a narrower national framework on advertising and minors — arguing that youth exposure to gambling marketing crosses provincial lines even though licensing itself cannot. The Biblioteca del Congreso de la Nación catalogued 35 separate gambling-related bills before Congress as of October 2024, the great majority concerned with ludopatía (problem gambling) prevention, advertising and protections for children and adolescents.
That pressure produced two competing 2024–2026 proposals. In November 2024 the Cámara de Diputados passed a 54-article bill with a comprehensive national advertising ban, mandatory biometric age verification via the national identity registry (RENAPER), payment-method restrictions (barring credit cards and welfare-linked accounts from funding online betting), a national self-exclusion registry, mandatory use of the “.bet.ar” domain, and school prevention programmes; it has sat in the Senate since. In May 2026 the national Executive sent its own, narrower 21-article bill directly to the Senate, focused on criminal penalties of three to six years for unlicensed operators, administrative blocking of illegal platforms via ENACOM and the Banco Central, and public-health measures channelled through SEDRONAR — without the Diputados bill’s blanket advertising ban. As of mid-2026 the two bills remain unreconciled, underscoring that even on advertising and minors — arguably the one gambling question with a plausible national dimension — Argentina has not yet legislated federally.
At provincial level the picture is more settled: most provinces with online licensing have written their own advertising restrictions and self-exclusion tools into their own gaming law (Buenos Aires Province’s Ley 15.131, CABA’s Ley 6.330, and equivalents elsewhere) — but, consistent with the constitutional architecture, none of it binds outside its own jurisdiction.
Taxation and the currency-control complication
Betting operators face tax exposure at two levels that rarely align. Nationally, Ley 27.346 (2016) created an Impuesto Específico sobre la Realización de Apuestas and an Impuesto Indirecto sobre Apuestas Online, collected as a percentage of the funds users deposit onto a platform; the rate is graduated by the operator’s residency and investment status, lower for domestic operators with genuine local investment and highest for operators based in low- or no-tax jurisdictions. Where the operator is foreign, Argentine banks and card issuers act as withholding agents at the point a domestic user funds an account — a mechanism formalised through AFIP (now ARCA) resolutions including Resolución General 5.228/2022, updated by Resolución General 5.791/2025. Provinces layer their own gross-revenue taxes on top, so a Córdoba-licensed operator pays national online-betting tax, Córdoba’s provincial gaming levy, and standard corporate tax — a stack a competing offshore, unlicensed site reached through a VPN never pays.
Argentina’s chronic currency controls have added a further complication distinctive to this market. Cross-border card payments were, for years, subject to the Impuesto PAIS (a tax on foreign-currency purchases, including card payments to platforms abroad) on top of ordinary VAT, meaning a bettor funding an unlicensed offshore account by foreign card could face a higher effective cost than one depositing locally. The Impuesto PAIS lapsed at the end of 2024 when the government did not renew it, but a 21% VAT still applies to digital services billed from abroad, and Argentina’s underlying dollar-access restrictions continue to shape how both licensed and unlicensed platforms move money in and out of the country.
Argentina’s gambling market in 2026
The result of 130 years of provincial, rather than national, gambling policy is a market simultaneously mature and structurally incoherent. Roughly 20 of 24 jurisdictions now licence some form of online betting, each with its own regulator, tax rate, self-exclusion register and advertising rule; three provinces have no online framework at all; and Congress, despite dozens of bills, has not passed a single national gambling statute since the old national Lotería was wound down in 2018. Industry and legal commentary increasingly describes this “mosaico” (mosaic) of two dozen regulators as a structure that was already outdated the day it consolidated, because online betting does not respect the provincial borders the Constitución Nacional uses to allocate authority over it. Anyone describing “Argentine gambling law” as a single thing is describing something that has never existed — what exists is 24 provincial answers to the same question.
