Tesla shares closed at $409.99 on May 18 after a 2.9% decline amid elevated trading volume and institutional stake adjustments, reflecting pressure from the recent OpenAI lawsuit verdict against Elon Musk and softening electric-vehicle demand. The company's first U.S. Model Y price increase in two years aims to support margins following a Q1 earnings beat, while ongoing advances in Full Self-Driving regulatory approvals and Cybercab production ramp provide longer-term support. Traders are monitoring today's session for momentum from broader equity moves tied to interest-rate expectations and any fresh autonomous-driving milestones that could influence near-term share-price action.

If the final session is shortened (for example, due to a market-holiday schedule), the official closing price published for that shortened session will still be used for resolution.
If no official closing price is published for that session (for example, due to a trading halt into the close, system issue, delisting, or other disruption), the market will use the last valid on-exchange trade price of the regular session as the effective closing price.
In the event of a stock split, reverse stock split, or similar corporate action affecting the listed company during the listed time frame, this market will resolve based on split-adjusted prices as displayed on Yahoo Finance. The target price will be adjusted proportionally to reflect any stock splits. Resolution will be based on the historical price data as shown on Yahoo Finance after any adjustments have been applied.
The resolution source for this market is Yahoo Finance, specifically the Tesla, Inc. (TSLA) "Close" prices available at https://finance.yahoo.com/quote/TSLA/history, published under "Historical Prices."
