Costco stock reached an all-time high of $1,096.50 on May 19, 2026. This surge fueled speculation about a potential stock split.
The stock has increased by over 25% in 2026. A split would mark the company's first since the year 2000.
Costco historically splits shares during growth periods to improve investor accessibility. However, management previously noted that fractional share ownership reduces the need for a split.
The company boasts robust financial health, earning a GF Score™ of 96 out of 100. An elevated P/E ratio suggests high investor expectations are already priced into the stock.
