Musk Loses OpenAI Jury Trial as SpaceX IPO Raises 'Muskonomy' Concerns for TSLA (NASDAQ:TSLA)

A California jury dismissed Elon Musk's lawsuit against OpenAI in under two hours on Monday, May 18, 2026, finding the AI company not liable for claims brought by the billionaire Tesla (NASDAQ: TSLA) CEO. The verdict landed on the same day a separate set of concerns — surrounding a prospective SpaceX IPO — sent TSLA shares down 3% to close at $409.99.

The OpenAI Verdict and SpaceX IPO: What Happened

• A jury in Oakland, California, rejected Musk's claims against OpenAI after three weeks of testimony, according to Yahoo Finance reporting.
• Musk had sought $134 billion in damages in the lawsuit, per the same report.
• The presiding judge was reportedly prepared to dismiss the appeal before the verdict was reached, according to Yahoo Finance.
• SpaceX is reportedly eyeing a 5-for-1 stock split as its IPO timeline accelerates, according to Yahoo Finance reporting.
• Wall Street analysts flagged the prospective SpaceX IPO as a potential source of competition for investor capital and Musk's management attention, according to Investing.com.

Why It Matters

The OpenAI lawsuit outcome removes a prolonged legal distraction for Musk, though the swift two-hour jury deliberation — after three weeks of testimony — underscored how little traction the $134 billion case ultimately gained. For Tesla investors, the more pointed concern on Monday, May 18, was the SpaceX IPO narrative: analysts, as cited by Investing.com, warned that a landmark public offering by SpaceX could draw institutional capital away from TSLA and split Musk's attention across multiple high-profile enterprises — a dynamic some on Wall Street have labeled the "Muskonomy" premium risk.

The SpaceX IPO, which could rank among the largest in history according to Yahoo Finance reporting, introduces a structural question about whether Tesla's elevated valuation — which has long incorporated a premium tied to Musk's broader influence — can hold if a rival Musk-led entity begins competing for the same investor base.

Wall Street View

As of the May 1, 2026 consensus, analyst sentiment on Tesla remains broadly constructive: 9 Strong Buy, 20 Buy, 24 Hold, 7 Sell, and 1 Strong Sell ratings. The Hold count rose from 21 in the April 1 consensus, suggesting modest softening at the margin. With a forward P/E of 163.1x (TTM — may not reflect the latest quarter), Tesla's valuation leaves limited room for narratives that question Musk's singular focus on the automaker.

Investor Takeaway

The dismissal of the OpenAI lawsuit closes one chapter of legal exposure for Musk, but the SpaceX IPO story is only beginning to take shape — and analysts have already flagged it as a potential headwind for Tesla's premium valuation. With the Hold count in the analyst consensus ticking higher and a forward P/E that demands sustained confidence in Musk's leadership, any perception of divided attention carries real weight for TSLA shareholders.
