MotoGP published its 2027 calendar on 25 September: 22 Grands Prix from Buriram on 7 March to Valencia on 28 November, with two new venues. Buenos Aires takes round four on 11 April at the Autódromo Oscar y Juan Gálvez, which last held a motorcycle Grand Prix in 1999, in place of Hungary's Balaton Park. Adelaide takes round 21 on 14 November on a street circuit, in place of Phillip Island.

By Victoria's account, Phillip Island did not lose on money. In February, Victoria's Minister for Sports and Events, Steve Dimopoulos, told the ABC that the organiser had asked to move the race to Melbourne's Albert Park and the state had refused. "We met every other request. We met the licence fee, we met everything else, in fact, went beyond it," he said. "We know that we could have kept [the race] in Victoria, had we sold out Phillip Island." A state that met the price of a Grand Prix lost it over the address.

Adelaide supplied the address. The day after Dimopoulos spoke, MotoGP, the South Australian Government and the City of Adelaide announced a six-year agreement running to 2032 inclusive, billed as "the first MotoGP Grand Prix to be held in a city-centre location". In August the state released the design for what the ABC reports as an A$96 million street circuit, a budget that excludes the temporary pit building and sits beside a separate A$15 million parklands package. The government forecasts an A$200 million a year economic benefit.

South Australia's own numbers are contested at home. Andrew Milazzo, a former deputy chief executive of the state's transport department, puts the annual taxpayer cost of the circuit's combined events, MotoGP and Supercars together, at A$90 million, and their net economic cost at around A$50 million a year. A government spokesperson answered that the report was "produced by known critics of the project" and "contains significant inaccuracies based upon false assumptions".

Buenos Aires arrives by a different road to the same kind of host. Argentina's round was not held in 2024 "por falta de asistencia económica del Gobierno nacional", for want of financial support from the national government, according to La Nación, and Termas de Río Hondo left the calendar after 2025. The return was announced by the city government in July 2025, on a four-year contract with Grupo OSD and Dorna. The city's own release of 30 July 2026 says the works, driven by the city through its sports secretariat and run by Autopistas Urbanas (AUSA), began in January and will conclude from the end of the year, for a circuit holding 150,000 people a day. Jorge Macri, head of the city government, called them "inversiones que nos posicionan como una ciudad atractiva ante los ojos del mundo", investments that make the city attractive in the eyes of the world, and named the next target as Formula 1. The release prints no figure.

Hungary shows the same rule from the losing side. Speedweek reports that Balaton Park's contract was not renewed after two Grands Prix, the decisive factor being a crowd of about 80,000 over three days that did "not fit with the long-term vision for the Motorcycle World Championship under Liberty Media". The alternative is the Hungaroring outside Budapest, and Speedweek says the move is held up because the investment, "running into the high double-digit millions, has not been approved by the state". The capital-city option exists on paper and waits on public money.

Around the two headline changes the pattern holds. Round three at Goiânia rests on the state of Goiás, which Diário de Goiás reported in March put R$250 million into the circuit and signed with Dorna and Brasil Motorsport in December 2024 for five rounds from 2026 to 2030. The season launch goes to Rio de Janeiro's Botafogo Beach on 21 February, announced in August alongside the city's mayor, and MotoGP's own release sold it with the claim that the 2026 launch in Kuala Lumpur "gerou mais de US$ 7 milhões em valor econômico". Portugal's extension to 2029, announced on 24 September, was voiced by the State Secretary for Tourism, Turismo de Portugal and the Algarve's tourism body, the last of which named what the date buys the region: "It also has the advantage of taking place outside the peak season." Portimão moves from 20 to 22 November in 2026 to 3 October in 2027.

The classics renew on different terms. Mugello extended through 2031 on 24 September after a record 178,723 spectators in 2026, with the circuit's chief executive, Paolo Poli, describing the commitment as made "together with Ferrari". Tuscany's regional president, Eugenio Giani, welcomed the deal without a published contribution. The classics hold their places on crowds. The changes, in both directions, turned on what a government would build and where.

What the promoter earns from any of these arrangements is not public. Liberty Media, which owns MotoGP, reports that primary MotoGP revenue comes from "(i) race promotion fees, (ii) media rights fees and (iii) sponsorship fees", and its second-quarter release says only that across the first half "Race promotion revenue grew due to race mix". Nothing in the release lets a reader tell whether Buenos Aires or Adelaide pays more than Phillip Island did.

Three of the 22 rounds remain provisional. Crash.net lists Buenos Aires and Adelaide as subject to homologation and the Circuit of the Americas as subject to contract. Both government-built venues now have to pass inspection on tracks that are, in one city, scheduled to finish works from the end of 2026 and, in the other, a design released in August 2026. The homologation reports, not the calendar, will say whether the public money bought a Grand Prix.
