Investors eye United Rentals as top candidate for next stock split amid rising share prices.

Wall Street is focusing on stock splits again after KLA and Booking Holdings made notable splits, lowering their high share prices to boost accessibility. Among three NYSE stocks—AutoZone, W.W. Grainger, and United Rentals—United Rentals is seen as the most likely to split due to its strong recent performance, retail-friendly business, and share price under $1,000. AutoZone is least likely because of its long-standing buyback strategy and very high share price, while Grainger maintains a premium price with steady buybacks and dividends. None have announced splits yet, but United Rentals fits the profile best if a split occurs next.
