Forecast Model

This shows the set's value since release and where our forecast expects it to go.
LEGO 42233-9 Mighty Machines Complete Set is a Technic Mighty Machines Series 1 set released in 2026. The complete collection includes all eight construction vehicles from the series, specifically a road roller, wheel loader, dump truck, cement truck, wrecking ball crane, mobile crane, bulldozer, and excavator. Each of these models has a moving function powered by LEGO Technic elements. The set also contains a collectible stat card for every vehicle.

Once it retires, which we expect in 2027, our forecast sees a pop of about 11% and a value near $52 within five years.
