Add the chicken and buffalo sauce to an Instant Pot.
Place the lid on the Instant Pot and make sure the steam release is set to “sealing”.
Press the poultry button and allow the chicken to pressure cook.
When the Instant Pot beeps 3 times, it's done cooking.
Wait 15 minutes for the Instant Pot to cool down before removing the lid.
Once the lid is removed, shred the chicken with two forks and toss with the buffalo sauce.
Remove from the Instant Pot and serve immediately with your favorite buffalo chicken recipe, or place in a plastic container in the refrigerator for later use.
