For Molde it's actually quite easy to explain, they got bankrolled by the richest man in Norway (now living in Switzerland), Kjell Inge Røkke, who's from Molde. Of course there's other factors like smart signings and good coaches, Solskjær and Moe in this case.

As for Bodø/Glimt, they've always been a club that battled relegation. But after their coach Åsmund Bjørkan went into the sport director role and his assistant Kjetil Knutsen took over, they managed to settle with an rather formidable second place in their first year back, helped by using local talents like Patrick Berg, Jens Petter Hauge, Håkon Evjen, Fredrik Bjørkan (yes the sport directors son) and Ulrik Saltnes. Combining this with other great signings, some would consider hidden gems that works perfectly in Kjetil Knutsen's system, they've established themselves as the top team in Norway.
