Turn the Instant Pot on to Saute mode. Add in hamburger and onion, cooking through.
Add the tomatoes, cumin, chili powder, curry powder and beef broth to the Instant Pot.
Without stirring, place the lid on the Instant Pot, ensuring the valve is set to the SEALING MODE.
Turn the Instant Pot on by hitting the CHILI/BEAN BUTTON and adjusting the time to set to 12 minutes. Allow the Instant Pot to cook and release naturally. Once there is no more steam you can set the valve to release.
If the chili isn't as thick as you'd like, add in the tomato paste and stir to ensure the tomato paste breaks down and heats through.
Serve and enjoy!
