This market will resolve to the largest company in the world by market cap on September 30, 2026, as of market close. The resolution source for this market will be a consensus of credible reporting.NVIDIA's commanding lead in AI accelerator chips and data center infrastructure underpins the 98.7% market-implied odds for it remaining the world's largest company by market capitalization at the end of September 2026. Recent quarterly results showed data center revenue more than doubling year-over-year, with strong demand for Blackwell systems and early shipments of the next-generation Rubin platform supporting forecasts for 70% revenue growth in the coming fiscal year. Trader consensus reflects NVIDIA's multi-trillion-dollar valuation gap over Apple and others, sustained by hyperscaler spending and ecosystem expansion. While a sudden broad market selloff or major supply disruption could narrow the lead in theory, the short timeframe to month-end makes such reversals highly improbable.
