The Rahal Letterman Lanigan driver took his first series pole with a 1m09.3321s on the Indianapolis Motor Speedway road course.
He topped Group 1 in the first part of qualifying with a 1m09.4639s before he was pipped to the top spot in Q2 by Arrow McLaren driver Alex Palou by 0.02s.
But progressing to the Fast Six, the Dane sealed his first series pole ahead of Rosenqvist (Arrow McLaren) and Palou.
Jack Harvey (RLL), Arrow McLaren’s Pato O’Ward and Kyle Kirkwood, who scored his maiden win for Andretti Autosport in Long Beach last month, complete the top six.
Group 1’s Q1 session saw Lundgaard lead Chip Ganassi Racing’s Marcus Armstrong, with Rosenqvist third, as the field set banker laps on their primary Firestones.
With less than five minutes to go, everyone ducked into the pits to grab a set of the softer alternates.
Simon Pagenaud was the first to lay a strong lap on these reds for Meyer Shank Racing, a 1m10.2625, but this was swiftly eclipsed by Team Penske driver Josef Newgarden’s 1m09.8402s.
Then the times came in thick and fast, Armstrong hitting P1 before Lundgaard slammed in a 1m09.4639s ahead of the New Zealander and Will Power (Team Penske).
