The event is “Largest Company end of July?” with multiple submarkets about which company…

What is happening now

Polymarket is hosting a date ladder event asking which company will be the world’s largest by market capitalization on July 31, 2026. The market groups eight separate binary markets—each asking about a different trillion-dollar company—under one event umbrella. As of July 10, 2026, NVIDIA dominates the betting at 88.5%, while all other candidates trade near 0% probability.

How the market is structured

This is a date ladder format with eight individual binary markets, each testing a different company:

• NVIDIA (threshold 0): 88.5% probability, $943K volume, $90K liquidity
• Saudi Aramco (threshold 5): 0.1% probability, $205K volume, $104K liquidity
• Microsoft (threshold 1): 0.2% probability, $177K volume, $70K liquidity
• Apple (threshold 2): 8.3% probability, $141K volume, $52K liquidity
• Alphabet (threshold 3): 2.2% probability, $106K volume, $50K liquidity
• Tesla (threshold 4): 0.1% probability, $169K volume, $72K liquidity
• Amazon (threshold 6): 0.1% probability, $98K volume, $80K liquidity
• Broadcom (threshold 7): 0.1% probability, $143K volume, $81K liquidity

The aggregate market has $1.98M total volume with $599K liquidity. The event resolves July 31, 2026 at 23:59 UTC based on consensus credible reporting of market caps at market close.

Path to the leading outcome

NVIDIA’s 88.5% price reflects expectations that its AI-driven growth trajectory will outpace all competitors. For this to materialize, the company must:

• Maintain or accelerate its >$3T market cap runaway premium over peers
• Continue delivering record AI chip demand and data center revenue growth
• Avoid significant valuation compression from regulatory scrutiny or competitive pressure

What could change the pricing

Several developments could dramatically shift probabilities:

• AI growth deceleration: If NVIDIA’s data center growth slows below expectations, Apple (currently 8.3%) or Microsoft (0.2%) could gain traction as safer mega-cap plays
• Market rotation to value: Saudi Aramco (0.1%) or ExxonMobil could surge if energy stocks benefit from geopolitical supply disruptions
• Regulatory intervention: Antitrust actions against NVIDIA’s AI dominance or Microsoft’s cloud partnership with OpenAI could create volatility
• Macro shock: A significant risk-off event could benefit established tech giants like Apple or Microsoft over high-growth AI names

Editorial read

The market’s skew toward NVIDIA reflects the concentrated AI narrative—with the stock trading at roughly 50x forward earnings and commanding a $3.2T+ valuation as of July 2026. The 88.5% price implies the market expects NVIDIA to extend its lead by at least $500B over Apple, which would require maintaining a premium of over 150% P/E versus the S&P 500.

The low liquidity on non-NVIDIA legs ($50K-$104K) means small price movements can swing probabilities significantly. With $600K total liquidity across all eight markets and the event still 21 days out, sharp moves are possible on earnings, Fed policy, or AI supply chain developments.

Notably, the market structure prevents direct comparison—only one company can win, but the date ladder format allows traders to express nuanced views on relative performance timing. The July 31 deadline creates a hard resolution point where market caps must be read from credible financial data sources at market close.
