What is the scientific consensus regarding where Hot Jupiters originally formed?
Answer
They formed farther out and subsequently migrated inward.
It is highly improbable they formed in situ because the intense heat near the star would have vaporized the necessary volatile materials long before a Jupiter-sized planet could accrete.
