Add chicken and broth to a 3- to 4-quart Dutch oven or soup pot. Bring to a simmer over medium-high heat, then reduce to medium-low. Cover and simmer for 15 minutes until chicken is cooked through and reaches 165°F.
Remove chicken from pot to a cutting board and shred with two forks. Return shredded chicken to pot.
Add beans, corn, green chiles, hot sauce, chili powder, onion powder, and salt. Stir to combine.
Cut cream cheese into cubes and stir into pot. Cover and simmer over medium-low heat for 10 minutes, stirring occasionally to melt the cream cheese.
If desired, mix cornstarch and water in a small bowl and stir into chili to thicken. Simmer until thickened.
Serve hot with chips, avocado, lime wedges, salsa, cheese, jalapenos, or your favorite toppings.
