Automotive & Transportation Conventions in Las Vegas

Automotive week in Las Vegas means SEMA and AAPEX, where aftermarket parts makers, installers, distributors, repair shops and retailers meet, with show cars all over the LVCC and the Strip. The rest of the transportation calendar is more specialized: clean commercial fleets at ACT Expo, car-wash operators at The Car Wash Show, and business-aviation operators and manufacturers at NBAA-BACE, which adds a static aircraft display at Henderson Executive Airport.

We track 5 automotive shows in Las Vegas with 5,000 or more attendees; 5 have confirmed dates between Oct 20, 2026 and May 17, 2027. The largest on the calendar is SEMA Show 2026, with a published figure of about 153,000 (2025 figure, per its source), followed by AAPEX 2026 (~45K) and NBAA-BACE 2026 (~17K).

Where they meet: LVCC hosts 4, Venetian Expo hosts 1 and Caesars Forum hosts 1 of these shows. Shows that span two venues are counted at each.

The busiest months are November 2026 and May 2027, with 2 automotive shows each (SEMA Show 2026, AAPEX 2026, The Car Wash Show 2027 and ACT Expo 2027).

Weeks that fill the city: we rate the week of Oct 19, 2026 (Packed, with NBAA-BACE 2026) and the week of Nov 2, 2026 (Sold-out, with SEMA Show 2026 and AAPEX 2026) as Packed or busier. Expect firmer hotel rates and earlier booking for rooms, dining and talent.
