America's Cup Naples 2027: four forecasts, one head count and no published model behind the billion-euro claims

Every Naples figure is a forecast, and the forecasts keep rising

The first estimate came on 15 May 2025, the day Italy was announced as host. Unimpresa, an association of small and medium businesses, published a short-term figure of about EUR 689.8 million through its research office. Its release breaks this into EUR 462.1 million of direct spending, about EUR 165 million of indirect effects and EUR 62.7 million of induced effects, using a multiplier of 1.1. It says the estimate adapts the Barcelona 2024 edition to Campania. It does not publish the underlying dataset.

On 10 and 11 June 2025 the Ministry of Tourism, working with Luiss Business School, presented its own study. ANSA reported a short-term impact of about EUR 690 million and a long-term figure that could reach EUR 1.2 billion. Sport e Finanza reported that Daniela Santanchè, then tourism minister, presented the study in Genoa. She said it was credible that every euro invested would generate four more. No published text defines what counts as "invested". We could not find the study itself online.

In October 2026 Sport e Salute, the state-owned company that implements the event, raised the forecast to between EUR 1.4 billion and EUR 1.7 billion. Solovela reported on 8 October 2026 that the figures were presented at the 66th Genoa International Boat Show and repeated by the America's Cup organisation on 5 October. The same article calls them preliminary estimates of revenue still to be earned. It also says the figure is not a net gain for public administrations. No author, model or study was named.

On 2 November 2026 Sport e Finanza, citing Affari & Finanza, reported a Banca Ifis analysis of EUR 1.6 billion. The bank's chief executive, Raffaele Zingone, called it a very high figure for a territory so narrowly defined, and compared it with the bank's EUR 2.1 billion estimate for the Giro d'Italia, spread across the whole country. That analysis adds direct spending during the race, effects spread over the following 12 to 18 months, and the value of new infrastructure.

From the first forecast to the latest, the headline rose by 132% (our calculation, EUR 689.8 million to EUR 1.6 billion). The visitor forecasts moved too, and in different units. Unimpresa expected 1.5 to 1.7 million visitors over 60 days. Sport e Salute expects 3 to 3.5 million visitors. Banca Ifis expects about 530,000 arrivals. These three figures count different things and cannot be lined up as one series.

The EUR 690 million appears twice, and the EUR 1.2 billion has three lives

The ministry's short-term figure of about EUR 690 million matches Unimpresa's EUR 689.8 million almost to the euro. Sport e Finanza's report of the ministry presentation says the study took Unimpresa's data, published a month earlier, as its starting point. It also says the ministry's figure confirms Unimpresa's first assessment. One estimate with two logos does not amount to two confirmations.

The EUR 1.2 billion has a looser status still. In the ministry's wording reported by Sport e Finanza, the long-term value "could exceed" EUR 1.2 billion and includes reputational and post-event effects. It is a ceiling scenario. It was later quoted as the event's value, including by Business People on 23 September 2026.

The same round number has two other uses. Catalan News reported in October 2024 that a Pompeu Fabra University report had expected the 2024 Cup's impact in Barcelona to exceed EUR 1.2 billion. And press reports put the cohesion-fund budget for the Bagnoli clean-up, a programme that predates the Cup, at about EUR 1.2 billion. That budget is not an event cost or an event benefit. The coincidence makes it easy to blend three numbers that have nothing to do with each other.

Unimpresa's own release is more cautious than its headline. It assumes an organising cost of EUR 100 million, 70% spent locally, and it mentions a hosting fee of EUR 50 million that could weigh on public finances if poorly managed. None of the later forecasts subtracts any cost.

What the newest forecasts add up to

The Banca Ifis figure is the most detailed in the press. As reported by Sport e Finanza, it has four parts. Direct spending during the race is EUR 850 million, of which lodging is EUR 444 million, restaurants EUR 183 million and shopping EUR 134 million. Superyachts add EUR 46 million. Deferred spending over 12 to 18 months adds about EUR 500 million. The infrastructure legacy adds EUR 220 million.

These parts sum to EUR 1,616 million (our calculation), which rounds to the EUR 1.6 billion headline. About 14% of the total is infrastructure value (our calculation). Building a sailing base is a cost to whoever pays for it. Counting it as an impact is a choice the bank made, and the same choice shaped its EUR 5.3 billion forecast for the 2026 Winter Games.

The bank also put a figure of up to EUR 9.3 billion on additional Made in Italy exports. That number rests on consumer interviews in six countries (the United States, Australia, New Zealand, Switzerland, France and the United Kingdom) and a reported 29% rise in willingness to buy Italian products. It is stated purchase intent, which should not be read as measured trade or added to the EUR 1.6 billion.

Sport e Salute's EUR 1.4 to 1.7 billion has no published breakdown at all. Solovela reports that the forecast was revised upwards mainly in light of the crowds at the September 2026 preliminary regatta. In the same article, the forecasts put Naples at 3 to 3.5 million visitors, which Solovela calls almost double the 1.8 million recorded for Barcelona. As the next sections show, that comparison sets a forecast for Naples against a count of visits in Barcelona.

The only measured number is a crowd count from a practice regatta

The second preliminary regatta of the 38th America's Cup ran in Naples from 24 to 27 September 2026. Sport e Salute's results, as reported by Juorno on 4 October and Solovela on 8 October 2026, give 278,893 presences across land and sea. That total splits into 252,520 visitors at the Race Village and 26,373 spectators on boats in the gulf. Juorno also reports 2,490 boats over the four days. Solovela says presences on the final day exceeded 120,000.

These are counts of attendance, and the method is not published. Nobody has said whether the Race Village figure comes from turnstiles, ticket scans, phone data or an estimate. A person who visited on three days may count three times. The figures cannot be read as unique people, as tourists or as nights in hotels. Solovela compares them with about 33,000 visitors at Barcelona's preliminary village. That comparison crosses venues, formats and counting methods.

Two statements about hotels point in different directions. On 30 September 2026 Teresa Armato, the city's tourism councillor, said hotel occupancy reached 100% and non-hotel accommodation 85% during the regatta, according to Juorno. No dataset or survey was named. Six months earlier, on 15 March 2026, Federalberghi Napoli, the hotel association led by Francesca Pagliari, reported a 3% fall in bookings and hotel occupancy down from 61% to 58% in January and February, according to Fanpage. Those figures cover hotels only, a different period, and make no mention of the Cup. Both are statements, and neither has a published method.

A larger figure travels with the regatta. Il Sole 24 Ore wrote on 23 September 2026 that up to 2.2 million visitors were expected in the city in September. Business People, the same day, called them 2.2 million expected arrivals. On 4 October Juorno reported about 2.2 million tourist presences for September 2026, against 1.8 million in September 2025, citing only "the analysis". The unit changes from visitors to arrivals to presences, and the status changes from expectation to result. No source is named in any of the three.

The area is not named either. For scale, ISTAT counted 3,862,329 nights in registered accommodation in the comune di Napoli in all of 2024. If the 2.2 million were nights in the comune, one month would equal 57% of that annual count (our calculation). That is one reason we do not use it. Naples statistics are unusually sensitive to which area and which unit is meant, as our analysis of three Naples numbers that don't agree shows.

What earlier hosts found after the racing

Barcelona hosted the 37th America's Cup in 2024. The University of Barcelona and the Fundació Barcelona Capital Nàutica produced a post-event study, released on 4 March 2025. Sail-World, in an article credited to America's Cup Media, reported a positive economic benefit of EUR 1.034 billion, 12,872 jobs equivalent and EUR 208.5 million in tax revenue. Grant Dalton, the America's Cup Event chief executive, commented on the results. The study's method is not described in any article we could open, and the organiser's own release did not load.

Before the event, Barcelona had a higher number. Catalan News, reporting an interview with economy councillor Jordi Valls on TV3 in October 2024, wrote that a Pompeu Fabra University report had expected an impact of over EUR 1.2 billion. Valls himself did not discuss the economic impact. The post-event figure is at least 13.8% below that forecast (our calculation). The forecast and the result appear to come from different universities, so the gap may reflect method as well as outcome. The picture is not fully clean, because Sport e Finanza, on 11 June 2025, described Barcelona's results as certified by Pompeu Fabra University, which leaves the relationship between the two studies unclear. The direction still matters for Naples, where the forecasts are rising and the first Barcelona lesson is that forecasts can exceed results.

Barcelona's visitor figures also come in two units. The study counted 1.8 million visitors over 59 days at the free event sites. It counted 460,819 people who came to Barcelona specifically for the event. The second figure is about a quarter of the first (our calculation). When Solovela's report sets Naples's forecast at almost double Barcelona, it compares a forecast with the larger of these two counts.

Auckland hosted the 36th Cup in 2021. The official evaluation, written by Fresh Info for the Ministry of Business, Innovation and Employment and Auckland Council and dated 30 June 2021, is a cost-benefit analysis. It found a net benefit to New Zealand of minus NZ$156.1 million, a benefit-cost ratio of 0.79. For Auckland alone, the net benefit was minus NZ$91.6 million and the ratio 0.85. Local government contributed NZ$215.2 million and central government NZ$133.2 million, a total of NZ$348.4 million that includes a NZ$40 million hosting fee. Of the 281,329 people who attended, 77.3% were from Auckland and 2.4% from overseas.

The Auckland report also states that GDP cannot be used as a valid measure of net benefit. Spending by residents who would have spent the money locally anyway is not new money. Costs borne by the public are part of the result. None of the Naples forecasts publishes either adjustment.

The Auckland attendance split shows why the adjustment matters. More than three in four people at the 2021 racing lived in Auckland. Their spending at the event was largely spending moved from elsewhere in the same city. A gross spending model counts it in full. A cost-benefit model counts only the new money that arrived from outside and sets it against what the public paid. The two methods can describe the same regatta and reach opposite signs.

Naples will face the same question. Unimpresa's own release expects about 1.1 million of its 1.5 to 1.7 million visitors to be local or national. Its figure of 400,000 to 500,000 international tourists is the part most likely to bring new money to Campania. No later forecast publishes a split between residents, Italian visitors and foreign visitors, and none says how many visitors would have come to Naples in the summer of 2027 without the Cup. That baseline is the number any credible evaluation would need first. An event that fills hotels which would have been full anyway adds little, and it can push out regular visitors who come back another year or not at all. After the Winter Games the Bank of Italy separated visitors who came for the event from those who would have come anyway. We found no equivalent measurement plan for Naples.

Italy has a recent precedent of its own. For Milano Cortina 2026, the Banca Ifis forecast of EUR 5.3 billion was repeated as an impact, and a pre-Games forecast of 725,000 spectators was presented as a closing balance. The only ex-post measurement came from the Bank of Italy. Its staff note of 28 August 2026 estimated that about 249,000 foreign overnight travellers came mainly for the Games and spent EUR 394 million, 13.8% of foreign overnight spending in February. Just over 50,000 more attended events but would have come anyway. The note estimates no GDP or net effect. It used the same survey method the Bank applied to the Jubilee 2025, and it is the kind of measurement Naples will need in 2027.

Who pays, and what has not been published

The legal basis is decree-law n. 96 of 30 June 2025, converted by law n. 119 of 8 August 2025, according to Normattiva. Article 7 names Sport e Salute as the implementing body and gives it EUR 7.5 million for 2025, taken from the budget of the Presidency of the Council of Ministers. We read the article's text in a consolidated reproduction, because the official Normattiva page did not return it.

The same article creates an America's Cup Venue Board of 11 unpaid members. Six are named by the organisers, including a president designated by Team New Zealand whose vote prevails in a tie. Five are named by the host side, three by the Government, one by Sport e Salute and one by the Comune di Napoli. Works at Bagnoli run through the existing extraordinary commissioner for the Bagnoli-Coroglio site, acting through Invitalia, and the clause states that it creates no new costs for public finances. Il Sole 24 Ore describes Mayor Gaetano Manfredi as mayor and commissioner for Bagnoli.

The decree also lets the Comune di Napoli spend up to EUR 30 million a year of its accumulated surplus in 2025, 2026 and 2027. That is permission to use the city's own money, and the maximum is EUR 90 million over three years (our calculation). Later provisions add free radio frequencies for the races, radio monitoring of EUR 384,991 in 2026 and EUR 692,384 in 2027, equipment of EUR 210,000 and EUR 200,000, and a VAT refund route for non-EU businesses. Two legal digests attribute these to decree-law n. 108 of 26 June 2026, which also caps hiring contribution relief at EUR 600,000 for 2026 and EUR 1.8 million for 2027. We confirmed that decree's title and Gazzetta listing on a legal-information site but did not open the Gazzetta text.

What is missing is a total. No document we opened states a hosting fee paid to the organisers, who would pay one, or the total public cost of the event across the State, the Region, the city and the port authority. Unimpresa's EUR 50 million hosting fee is its own assumption. Catalan News reported that EUR 56 million of public funds was spent in Barcelona. Auckland's evaluation itemised NZ$348.4 million of public spending by year and sector. Naples has published decree lines.

The Bagnoli figures make the gap harder to see. Il Sole 24 Ore put total resources for the Bagnoli regeneration at about 1.7 billion on 23 September 2026. Sport e Finanza reported a EUR 1.25 billion plan in October 2025, with EUR 150 million dedicated to the Cup. Juorno cited EUR 1.267 billion of cohesion funds in June 2025. These are budgets for a decades-old clean-up of a former steelworks. Only a part is attributable to the event, and that part has not been set out in any official document we opened.

What this means for travelers, businesses and analysts

Travelers planning Naples for 2027 should expect the busiest weeks around the racing. The Louis Vuitton Cup is reported to start on 22 May 2027, and the Match starts on 10 July. The September 2026 regatta drew large crowds to the waterfront, and the city reported full hotels for those days. Neither the crowd count nor the hotel claim has a published method, so treat them as signals only. If your dates are flexible, the weeks outside the race calendar are the safer choice. Our Naples travel guide and where to stay in Naples cover the neighbourhoods closest to the waterfront.

Tourism businesses and investors should read every billion-euro figure as a scenario. None nets out costs, displacement or the spending of residents who would have spent locally anyway. Auckland's evaluation shows how large those adjustments can be, and Barcelona's post-event figure came in below an earlier forecast. Hotel demand evidence for Naples is mixed, with a hotel association reporting softer bookings in early 2026 and a councillor reporting full hotels in September. This is not investment advice. Plan capacity and pricing on bookings you can see, and on the event calendar, rather than on the headline. Tourism's place in the wider economy is covered in our analysis of tourism's share of Italy's GDP.

Journalists and analysts can cite the following, each with its label. The forecasts are EUR 689.8 million (Unimpresa, 15 May 2025), about EUR 690 million short term and up to EUR 1.2 billion long term (Ministry of Tourism and Luiss, June 2025, building on Unimpresa), EUR 1.4 to 1.7 billion (Sport e Salute, October 2026) and EUR 1.6 billion (Banca Ifis, November 2026). The measured count is 278,893 presences over four days in September 2026. The public money in the law is EUR 7.5 million for 2025, permission for the city to spend up to EUR 30 million a year of its own surplus, and small radio and hiring lines. The comparators are Barcelona's EUR 1.034 billion after an earlier university forecast of over EUR 1.2 billion, and Auckland's ratio of 0.79. Do not repeat the ministry and Unimpresa figures as independent confirmations, the EUR 9.3 billion export intent as impact, the 2.2 million September figure as a measured result, the Bagnoli budgets as event cost, or Naples's 3 to 3.5 million visitors as double Barcelona.
