NVIDIA's commanding lead in the race for the largest company by market capitalization at the end of May stems from its entrenched dominance in AI accelerators and sustained investor enthusiasm for its graphics processing units powering large language model training. Recent quarterly results and supply chain updates have reinforced expectations of continued revenue growth from hyperscalers and enterprise adoption, keeping the chipmaker's valuation well ahead of Alphabet and Apple. With just two weeks remaining, the narrow window leaves little room for meaningful shifts from earnings surprises or broader market swings, though an unexpected regulatory setback or sharp AI demand slowdown could narrow the gap.
