Mortgages in 47 seconds: Better’s new ChatGPT app targets lenders Rocket and UWM

Bullish (0.8)Impact: High

Published on March 5, 2026 (3 hours ago) · By Vibe Trader

Better.com, an online mortgage firm, has partnered with OpenAI to launch a ChatGPT-powered app that can reduce mortgage underwriting times from approximately 21 days to as little as 47 seconds, according to CEO Vishal Garg in an interview with CNBC [1]. The tool integrates Better’s mortgage engine with OpenAI’s models, automating dozens of underwriting checks for loan officers at banks, brokers, and fintech firms [1]. This platform is specifically targeting industry leaders such as Rocket Mortgage (RKT) and United Wholesale Mortgage (UWM), enabling rival lenders to approve loans faster and reduce operational costs [1].

The app, set to be announced later Thursday, is designed to dramatically accelerate the underwriting process for both mortgages and home equity loans, making it cheaper, faster, and easier for American families to finance a home, according to Giancarlo Lionetti, OpenAI's chief commercial officer [1]. Historically, mortgage creation has been a lengthy process, often taking weeks due to numerous steps and regulatory requirements. The introduction of this AI-driven solution could reshape the U.S. home-loan market, which originates more than $1 trillion in mortgages annually [1].

Better’s initiative marks a strategic pivot from being primarily a consumer lender to offering 'mortgage-as-a-service' technology for other mortgage players. Garg emphasized that the app allows competitors to move faster, potentially saving lenders an average of 21 days per loan and reducing underwriting costs, which could ultimately benefit consumers through lower fees [1]. Garg also noted that large public companies like Rocket, UWM, and Pennymac currently charge about 1.5% to underwrite mortgages, amounting to $20 billion paid by the American public annually [1].

No specific market reactions or analyst opinions were mentioned in the article, but the launch is positioned as a significant technological advancement with the potential to disrupt the current mortgage industry landscape [1].

CONCLUSION

Better.com’s partnership with OpenAI to launch a ChatGPT-powered mortgage underwriting app represents a major technological leap, promising to cut processing times from weeks to seconds and reduce costs for lenders and consumers alike [1]. By targeting industry leaders such as Rocket Mortgage and UWM, the platform could significantly alter competitive dynamics in the U.S. mortgage market [1]. The move is expected to have a high market impact, given the scale and potential cost savings involved.
