Booking Holdings Positioned for Growth Amid Valuation Gap with Airbnb

Booking Holdings (BKNG) is emerging as a compelling alternative to Airbnb (ABNB) for investors seeking exposure to the travel sector, supported by stronger revenue growth and a significantly lower valuation. While Airbnb has captured substantial investor attention, Booking's diversified portfolio—which includes Priceline and Agoda—provides a robust foundation for continued market share gains. The broader travel industry is projected to grow at a compound annual growth rate (CAGR) of 11.1% through 2028, according to Technavio. Booking is well-positioned to capitalize on these tailwinds, having reported 13% revenue growth in full-year 2025, with a notable acceleration to 16% in the fourth quarter. In comparison, Airbnb delivered 10% revenue growth for the same period. Despite these stronger fundamentals, a mismatch exists in stock performance. Booking's share price has declined approximately 4% over the past year, while Airbnb's has risen roughly 23%. This divergence is reflected in the valuation metrics: Booking trades at a forward price-to-earnings (P/E) ratio of 17.8 and a PEG ratio of 0.79, whereas Airbnb carries a forward P/E of 27.6. Looking ahead to 2026, Booking has issued optimistic guidance, projecting Q1 revenue to increase by 14% to 16% year-over-year. Full-year revenue growth is expected to remain in the low double digits, with adjusted EBITDA growth projected to outpace revenue, indicating expanding profit margins.
