The following year he moved to the United States and competed in the Cooper Tires Formula Ford Zetec Championship in which he finished 5th after winning four consecutive poles and seven podium finishes. He won the 2005 Indy Lights Series championship in his rookie season for Brian Stewart Racing despite only winning a single race.
He continued with the team in 2006 and won 3 more races, including the Freedom 100 at Indianapolis Motor Speedway (becoming the first driver from New Zealand to do so) and placed third in championship points despite missing two races due to an emergency appendectomy. While missing out on the drivers title the team was still able to claim their second consecutive entrants championship because they were able to replace Wade with a reserve driver for those events. He narrowly missed the title by 11 points and would have easily clinched his second drivers championship had he started either of those events.
He drove in the A1 Grand Prix series as practice driver for A1 Team New Zealand in the round in Taupō, New Zealand, and China.[1] He returned to the Indy Lights Series in 2007 for AGR-AFS Racing where he finished 3rd.

Cunningham (inside) racing in Indy Lights in 2008
In December 2007 Cunningham tested an IndyCar Series machine for the first time at Sebring as a reward for his results with their satellite team in the Indy Lights Series, driving the Andretti Green Racing IndyCar normally driven by Marco Andretti.[2]
Wade's brother Mitch made his Firestone Indy Lights Series debut (formerly the Indy Pro Series) in 2008 for Brian Stewart Racing, the same team with whom Wade had his initial success. Wade made a handful of starts in the series in 2008, both for Brian Stewart and in the Mid-Ohio double-header for the new Alliance Motorsports team.
Cunningham won again that race in 2010 in a one-race deal for the Schmidt team, becoming the only three-time winner of the Freedom 100.
Sam Schmidt announced 11 February that Cunningham would make his Izod IndyCar Series debut in 2011 with Sam Schmidt Motorsports in a three race deal. He qualified 8th on debut at Texas Motor Speedway for the Firestone Texas Twin 275s and posted a season and career best IndyCar finish at the Indy Kentucky 300 when he finished 7th a mere 0.702 seconds from the lead.
