Cook bacon in a large pot or Dutch oven over medium heat until crisp. Remove bacon and set aside, leaving rendered fat in the pot.
Add onion and celery to the pot and cook until softened, about 5-7 minutes.
Pour in 1/2 cup white wine and bring to a simmer, scraping up any browned bits from the bottom of the pot.
Add potatoes and stock to the pot. Bring to a boil, then reduce heat and simmer until potatoes are tender, about 15-20 minutes.
Add clams to the pot and cook until they open, about 5-7 minutes. Discard any clams that do not open.
Add fish and corn to the pot and cook for another 3-5 minutes, or until fish is cooked through.
Stir in heavy cream and smoked salmon. Heat through.
Add shrimp and cook until pink and opaque, about 2-3 minutes.
Season with salt and pepper to taste.
Garnish with chopped chives and crumbled bacon before serving.
