Canon
InThor: Ragnarok,  Thor and Bruce can be seen getting closer, as they work together along side Loki and Valkyrie as they try to defeat Hela. In a deleted sceen, they can be seen getting thrown against each other, while on a ship.

Fanon
Shipping between the two started in the comics as well as in the first Avengers film, but was a more rare pair. Shipping took off with the release of the Thor: Ragnarok film. Many believe the two kissed during a deleted scene.
