SIMI · 2026

Agoris analysis · updated June 2026

Key takeaways

• 24th edition on 8, 9 and 10 December 2026 at Paris Expo Porte de Versailles, the second year at this new site following the structural relocation of 2025 from the Palais des Congrès Porte Maillot. SIMI is the annual gathering for French commercial property, organised by Infopro Digital since its creation in 2001 (24 years of operational continuity, same organiser).
• 2025 results: 26,052 professionals, 470 exhibitors, 115 speaking slots. SIMI is not a volume trade show like the SMCL; it is an ultra-qualified trade fair targeting a narrow audience (property investment companies, developers, asset managers, advisers, large-account property departments, metropolitan authorities).
• 3 thematic pillars for 2026 announced by the organiser: transforming the existing stock (financing, decarbonising, reinventing uses), producing value (investing, operating, steering performance), contributing to the economy (property as strategic infrastructure). Clear reading: decarbonisation and the redevelopment of existing assets remain at the strategic core for 2026, in continuity with the 2025 Grands Prix.
• Operational management led by Aminata Sy, who succeeded Catherine Sachreiter. Editorial continuity confirmed: conferences co-organised with the IEIF (conference partner, not co-organiser of the trade show, a distinction that comes up regularly in the press).
• Future City Lab renewed for 2026 after its launch in 2025: a day dedicated to AI + territorial innovation on Thursday 10 December 2026, with an announced plenary, "Can AI be a lever for emerging from the crisis?". A clear signal of the place AI is taking in the commercial property value chain.

Quality of the visitor base

26,052 professionals in 2025 over 3 days, representing a very high business density per m² of show floor. The majority of attendees are decision-makers: senior management, investment management, development management, asset management, and property departments on the user side. SIMI has historically operated as a place of signature: announcements of fundraising rounds, presentations of projects entering marketing, and investor / developer meetings.

Activities & community

Conference programme

150+ conferences over 3 days announced for 2026 (115 speaking slots in 2025, an expanded programme for the 24th edition). Conferences co-organised with the IEIF (Institut de l'Épargne Immobilière et Foncière) covering market analysis, property fund performance, and investment conditions. Formats: sector opening plenaries, thematic debates on the 3 pillars, technical workshops, and market study presentations.

Awards & accolades

Grands Prix SIMI, jury chaired in 2025 by Stéphanie Bensimon (Head of Real Estate, Ardian). 2025 winners:

• Office building: Engie Harmony, 94,811 m² on the former PSA site in La Garenne-Colombes. An emblematic operation converting a historic industrial site into a tertiary campus.
• Business and industrial premises: ACTI-HALL Vaires-sur-Marne, 26,252 m² on a redeveloped industrial brownfield.
• Logistics and courier property: the mixed-use DAHER / SIMAERO Tremblay-en-France building, 9,000 m², developer Barjane.
• Jury's favourite: Green Campus Poissy Stellantis, 72,000 m², 8,200 employees, architect Patriarche.
• The Housing and Accommodation Prize and the Patronage & Solidarity in the City Prize round out the list of winners in additional categories.

Reading of the 2025 winners: 3 of the 4 main prizes reward redevelopment of existing assets (PSA, industrial brownfield, Stellantis site), which validates the 2026 editorial positioning ("transforming the existing stock" as the first pillar).

Satellite events

Future City Lab: renewed for 2026 after a successful launch in 2025. A day dedicated to AI + territorial innovation on Thursday 10 December 2026. Flagship plenary announced: "Can AI be a lever for emerging from the crisis?". A format designed to bring local authorities, property operators and tech players into dialogue.

Community & networks

Conference partnerships with the IEIF. Strong media coverage by the specialist press (Business Immo, Décideurs Magazine, Le Moniteur). Official SIMI app for exhibitor / visitor matchmaking.

Policy & CSR initiatives

Sustainable development policy led by Infopro Digital: limiting the carbon footprint of the trade show, progressive LED lighting on stands and activity zones, a waste-sorting policy. Beyond the operational side of the show, decarbonisation is positioned as the strategic editorial core for 2026: the first pillar ("transforming the existing stock: financing, decarbonising, reinventing uses") and the choice of 2025 Grands Prix winners that reward the redevelopment of existing assets versus new construction.

How the trade show has evolved

Trajectory analysis

In 2026 SIMI is holding its second edition at its new site. The 2025 move from the Palais des Congrès Porte Maillot to Paris Expo Porte de Versailles was presented as structural by the organiser ("clearer, smoother, more business") and validated by the 2025 figures (26,052 professionals, 470 exhibitors, 115 speaking slots). 2026 will tell whether the "new site" effect holds in the second year, a key indicator for exhibitors hesitating to invest in a permanent location. On the editorial side, continuity is total: same organiser since 2001 (Infopro Digital), same conference partner (IEIF), same Grands Prix format, Future City Lab renewed. Operational management has changed (Aminata Sy succeeding Catherine Sachreiter) with no visible break in the 2026 positioning.
