Soak the wooden skewers in water for at least 30 minutes.
In a large bowl, combine the chicken cubes with salt, black pepper, chili powder, and olive oil. Toss until evenly coated.
Assemble each skewer by alternating peach pieces, chicken, and jalapeno chunks until filled.
Preheat the air fryer to 375°F (190°C).
Lightly brush the assembled skewers with olive oil to prevent sticking.
Arrange the Jalapeno Peach Chicken Skewers in a single layer inside the air fryer basket. Cook in batches if necessary.
Air fry for 11–12 minutes or until the chicken reaches an internal temperature of 165°F (74°C).
Meanwhile, combine all peach glaze ingredients in a saucepan over medium heat. Stir until smooth and warmed through.
Brush the cooked skewers generously with the warm peach glaze.
Serve immediately while warm.
