Markets currently price NVIDIA's chance at 76.0%, a position that has. Trading volume stands at $6.5M. The contract resolves based on market capitalization at the close on December 31, 2026, as reported by a consensus of credible sources — a simple but consequential mechanism that ties the outcome to a single, verifiable number. That the favored outcome assessment reflects a tight race. The contract has traded as low as 42.0% and as high as 80.5% over its lifetime, a range that underscores how sentiment can swing. While NVIDIA currently leads, the spread of probability means no outcome is treated as a foregone conclusion. The other companies, including the rest of big tech, remain distant outsiders capturing only a negligible fraction of the odds. Traders track quarterly earnings, semiconductor demand, AI adoption, and regulatory moves, all of which can jolt market caps. But the market does not require a forecast of these forces; it simply asks which name tops the list on December 31, 2026. That simplicity makes it a clean gauge of how investors rank the long-term trajectory of the world's most valuable firms. Because the deadline is fixed, traders must weigh the current hierarchy against the potential for breakthroughs, busts, or buyouts that could upend it. These figures were last updated 10 min ago.
