A “historic day,” as Beppe Marotta described it, marks the start of a financial revolution for Inter Milan and AC Milan as the San Siro project finally begins.

Following the signing of the deed on Wednesday, the two clubs have officially become joint owners of the San Siro.

Therefore, setting the stage for a redevelopment that aims to double stadium revenues within the decade.

According to La Gazzetta dello Sport, the transformation will turn the Meazza into a multi-purpose, continuously active complex: a stark contrast to its current matchday-only model.

Currently, both clubs generate around €80 million per season from ticketing, hospitality, and matchday activities.

Once the revamped venue becomes fully operational, projections suggest annual revenues could climb to €180 million per club starting from 2031-32.

By comparison, Inter’s record-breaking season during their Champions League run to the final in Munich brought in €98.8 million from stadium activities: a figure soon to be dwarfed by future projections.

The clubs also expect a massive leap in commercial income.

Combined naming rights and sponsorship deals could be worth up to €25 million annually, more than double Juventus’ current €10 million deal.

Inter and Milan plan to open the naming rights tender by late 2026, taking cues from the lucrative English market.
