The current commercial agreement, setting out the terms under which teams race and the share of revenues, expires at the end of 2020 and the new one will run to 2026.
"As far as Ferrari, we are ready to sign. We would like to sign it I think even quite soon," team boss Mattia Binotto told a video news conference at the Hungarian Grand Prix.
"Looking ahead with clarity is important. So some are ready to sign," he added.
"I think we are as well happy, because we know that F1 has understood the importance of the role of Ferrari in Formula One. That for us was key and so we are satisfied from that."
McLaren Racing chief executive Zak Brown said the new agreement secured "a strong basis for the sustainability, growth and success of Formula One and all its stakeholders.
Formula One chairman Chase Carey said in May that negotiations over a new Concorde Agreement were on the back burner due to a crisis that has hit the teams and sport financially.
Formula One wants to create a more level playing field to improve competition, reduce costs and provide a fairer distribution of revenues.
Ferrari have historically enjoyed special payments as well as the ability to veto changes they deem to be against their interests.
"I don't think we're that far off having something that we can all sign," he told reporters. "There's still a few talking points which I think will happen in the short term."
