Friday's confirmation of Turkey's return from 2027 has cemented a packed 24-race calendar through to 2031, yet the contractual security across Formula 1's venues varies widely.
The Dutch Grand Prix faces immediate jeopardy, with Zandvoort's contract expiring at the end of this season.
The circuit opted for a single-year extension rather than committing long term, meaning 2026 will mark its final appearance before departing the schedule.
Just one year behind sits Las Vegas, whose deal concludes in 2027, although the American street race appears more likely to secure an extension given F1's push into the United States market.
At the opposite end of the spectrum, Miami boasts the longest commitment, locked in through 2041 following a 10-year extension agreed last year. Australia follows with a deal through 2037, whilst Bahrain's contract runs until 2036.
Austria's Red Bull Ring recently secured an extension matching Miami's longevity, also committed through 2041, whilst traditional European venues enjoy varying levels of security. Silverstone holds a deal through 2034, Monaco through 2035, and Monza through 2031.
Singapore (2028), Suzuka (2029), and Mexico (2028) occupy the middle ground, whilst Saudi Arabia, Azerbaijan, Abu Dhabi, and Brazil all hold contracts through 2030.
Spa-Francorchamps and Barcelona now operate under a biennial rotation agreement through 2031, with Turkey's freshly signed five-year deal completing the calendar through the same year.
