Which mcu film had the highest budget?

According to the evidence cited, the third and fourth films in the Avengers series—Avengers: Infinity War and Avengers: Endgame—were produced back‑to‑back and together cost more than $1 billion. This combined figure exceeds the budget of any other individual Marvel Cinematic Universe film that has been publicly disclosed. The record for the single most expensive film overall is held by Star Wars: The Force Awakens, with a net budget of $536 million, but that is outside the MCU. Because Hollywood accounting can obscure exact numbers, the $1 billion figure for the Infinity War/Endgame pair is the highest confirmed spending within the MCU. No other MCU film in the available source list is reported to have a budget approaching that level.
