Mario Kart World Tops Nintendo Switch 2 Best-Sellers as Console Sales Near 20 Million Units Worldwide

Mario Kart World remains the best-selling Nintendo Switch 2 game by a wide margin, according to Nintendo's most recent sales disclosures, as the console itself approaches 20 million units sold worldwide less than a year after its launch.

Nintendo reported that Mario Kart World had sold 14.70 million copies as of March 31, 2026, the most recent date for which the company has published detailed software figures, making it not only the top-selling Switch 2 title but also the fastest-selling game in the Mario Kart franchise's history. The racing title has been a consistent driver of hardware sales since the Switch 2 launched on June 5, 2025.

Nintendo's official sales disclosures list only a handful of Switch 2 titles that have crossed the one-million-unit threshold so far, a reflection of how young the console's software library remains compared with the original Switch, which has amassed titles selling in the tens of millions over its nine-year lifespan. Behind Mario Kart World, Donkey Kong Bananza ranks as the second-best-selling Switch 2 exclusive, with 4.52 million copies sold as of the same March 31 reporting date.

Pokémon Pokopia, a social simulation and sandbox title developed by Game Freak and Omega Force, ranks among the console's strongest performers despite launching later than several other top titles. Nintendo's official figures put Pokopia's sales at 2.41 million units as of March 31, though the company has separately indicated that global sell-through for the game surpassed 4 million units within roughly five weeks of its release, suggesting its official ranking is likely to climb significantly when Nintendo next updates its sales data.

Pokémon Legends: Z-A, released in an enhanced Switch 2 Edition, has sold 3.94 million copies, according to Nintendo's disclosures, making it another of the console's clear standout performers. Kirby Air Riders, a kart-racing spinoff developed jointly by Bandai Namco Studios and Sora Ltd., has sold 1.87 million units. Rounding out Nintendo's officially disclosed list of Switch 2 million-sellers is Hyrule Warriors: Age of Imprisonment, a hack-and-slash title developed by AAA Games Studio, which has reached 1 million units sold.

Nintendo has not yet published a full top-10 ranking of Switch 2 software sales, unlike the extensive historical rankings the company maintains for the original Switch platform. Industry analysts and outlets that track Nintendo's sales disclosures have noted that the newer console's software library simply has not had enough time to produce ten titles crossing the one-million-unit mark, a gap expected to narrow as more games are released and existing titles continue accumulating sales.

The console's overall hardware performance has significantly outpaced Nintendo's own projections. The company shipped 19.86 million Switch 2 units worldwide during the fiscal year ending March 31, 2026, exceeding its internal guidance of approximately 19 million units by roughly 860,000 units. Independent sales trackers estimate that global sell-through, meaning units actually purchased by consumers rather than shipped to retailers, had reached approximately 19.6 million by the console's first anniversary in June, indicating minimal buildup of unsold retail inventory.

In the United States specifically, market research firm Circana reported that the Switch 2 sold 5.9 million units during its first 12 months on sale, making it the second-fastest-selling video game hardware launch the firm has tracked since 1995. Only the Game Boy Advance, which sold 6.5 million units in its 2001 debut year, moved faster during a comparable launch window. The console has also consistently outsold Sony's PlayStation 5 in monthly and quarterly U.S. sales comparisons throughout 2026, while Microsoft's Xbox has fallen further behind both competitors, with the company no longer publicly disclosing detailed console shipment figures.

Software sales have kept pace with hardware demand. Nintendo reported that a combined 48.71 million Switch 2 games were sold during the fiscal year ending March 31, 2026, a figure the company has cited as a key driver behind what it has described as its most profitable fiscal year on record. Nintendo has forecast an additional 16.5 million Switch 2 hardware units will be shipped during the current fiscal year, which runs through March 2027.

Beyond its Switch 2 catalog, Nintendo continues to support the original Switch platform, which has now sold 155.92 million units worldwide as of March 31, 2026, cementing its position as Nintendo's best-selling home console ever and placing it ahead of the Nintendo DS in the all-time hardware rankings, trailing only Sony's PlayStation 2 among all video game consoles sold historically. Mario Kart 8 Deluxe remains the best-selling individual Switch title, with roughly 69.56 million copies sold over the platform's lifetime, followed by Animal Crossing: New Horizons and Super Smash Bros. Ultimate.

With several major new releases having reached the Switch 2 in the months since Nintendo's most recent detailed sales disclosure, including titles such as Splatoon Raiders and enhanced Switch 2 editions of existing franchises, analysts expect Nintendo's next quarterly sales update to reveal a meaningfully expanded roster of million-selling Switch 2 titles, potentially producing the kind of full top-10 breakdown that has so far remained possible only for the aging original Switch platform.
