Last August, Hamilton signed a two-year contract with the team, which was widely assumed to be fixed for the full term and left open the possibility for Mercedes to take Antonelli in 2026.
However, Hamilton was able to use escape clauses to miss the second year and take up an offer from Ferrari, leaving his seat free for 2025 and giving Mercedes the chance to take Antonelli as early as next year.
Antonelli, who is just 17 years old, will make his Formula 2 debut this season with Prema having won Italian F4 in 2022 and the Formula Regional European Championship with the team last year.
Wolff has compared the situation with 2014, when the team was keen to sign Max Verstappen but had nowhere to put him, while Red Bull was able to offer him a Toro Rosso seat for the following year.
“There was a situation many years ago where we had the opportunity to let Max drive,” Wolff told Austrian broadcaster ORF. “And that wasn't possible back then because we simply didn't have a cockpit.
“[Nico] Rosberg and Hamilton were tied to us long-term, and Red Bull naturally seized the opportunity. They gave him a contract with Toro Rosso, with the possibility of driving for Red Bull the following year.
“We then lost the young driver, and you can see how successful he has become.
"And precisely because we have a junior on the horizon who is really driving at a very high level, I simply wanted to keep this option open."
