Although NASCAR is “very hopeful” about going back to Mexico in 2026, they will not commit to it….
Back in March, journalist Jordan Bianchi shared that NASCAR was “very adamant” about getting an international date on the schedule, including discussions with both Mexico City and Montreal. Teams and organizers were reportedly optimistic, but until the date was officially secured, NASCAR delayed releasing the full schedule .

Meanwhile, in early March 2025, NASCAR sources told Bob Pockrass that despite swirling rumors, the Mexico City Cup race scheduled for June was “good to go,” and that Daytona Road Course was simply held as a contingency plan .
However, those deliberations in March mainly centered on the 2025 event. The talks around 2026 are still preliminary. Country-wide promoters (like Mexico City GP and OCESA) have expressed interest in hosting IndyCar in 2026, but there’s been no formal announcement from NASCAR about a Mexico Cup race that year .
2025 Mexico Cup race Confirmed—happened in June
2026 Mexico Cup race Under active discussion; NASCAR hopeful but not confirmed
So yes, NASCAR remains optimistic—and they’re making plans—but until contracts are formally signed and dates finalized, they can’t commit to a 2026 return just yet.
