Costco (COST) split speculation is getting louder as the warehouse club keeps trading near record territory. The stock has been one of 2026’s standout defensive names, helped by investors leaning into retailers that can keep traffic steady even when consumers are careful with spending.
Costco’s share price has pushed above the $1,000 mark, which naturally fuels talk of a split, but that is more of a market psychology story than a business story. Costco last split its stock in 2000, and the recent chatter does not change the company’s operating outlook or earnings power.
