The One Chip Challenge chip is rated at around 12.5 million Scoville Heat Units (SHU) for the 2024 edition, making it one of the hottest chips ever produced

. Previous versions, such as the 2023 Paqui One Chip Challenge, are made with Carolina Reaper and Scorpion peppers, which individually range from about 1.5 million to over 2 million SHU, but the chip itself is not officially rated on the Scoville scale

. There are other extremely hot chips branded as "One Chip Challenge," such as Fiery Jack's version, which claims up to 16 million SHU, even hotter than the Paqui chip

. In summary:

• 2024 Paqui One Chip Challenge: approximately 12.5 million SHU

• 2023 Paqui One Chip Challenge: made with Carolina Reaper and Scorpion peppers (~1.5 to 2.2 million SHU peppers), but no official chip rating

• Fiery Jack's One Chip Challenge: up to 16 million SHU (different product)

The 12.5 million SHU rating is significantly hotter than common hot peppers like the Carolina Reaper alone and far exceeds typical spicy foods, making the One Chip Challenge extremely intense.
