AI stocks now 45% of S&P 500 market cap, up 20 points since ChatGPT launch

AI-related stocks now account for 45% of the S&P 500’s market cap, a 20-point rise since ChatGPT’s 2022 launch. NVIDIA being the largest company by market cap on April 30 is at 99.6% YES.

This market trades at 99.6% YES, up from 99% just 24 hours ago. With only 7 days remaining until resolution, traders are treating this as effectively settled. Active sub-markets show consistent pricing, with little disagreement about NVIDIA holding the top spot.

The order book requires $230,339 to move the price by 5 percentage points, pointing to institutional-level participation. Total 24-hour trading volume is $336,553 in face value, with $267,697 in actual USDC traded, confirming solid liquidity.

A YES share at 99.6¢ offers almost no return. The market has priced in NVIDIA’s position. Unexpected negative news could still move these odds, but with 7 days left and a 0.4% gap to close, the window for a reversal is narrow.

Watch for NVIDIA’s Q2 earnings announcements and any regulatory developments that could shift trader confidence before the April 30 resolution date.
