United Wholesale Mortgage, one of the biggest mortgage originators in the country, just swung from a $170.4 million profit to a $451.9 million loss in a single quarter. The culprit: a $603 million hole blown through its balance sheet by a bad interest-rate hedge.

The company responded by raising $2.05 billion in fresh capital, a deal it’s calling the largest equity raise in mortgage industry history.

What went wrong

UWM Holdings, which trades on the NYSE under UWMC, reported its second-quarter 2026 earnings with a number that made shareholders wince. Revenue came in at $888 million, but that figure was dragged down dramatically by a $603 million loss on an interest-rate hedging position tied to falling rates.

Loan origination volume also declined during the quarter. UWM originated $39.7 billion in mortgages in Q2, down from $44.9 billion in Q1 2026.
