— Elon Musk (@elonmusk) August 4, 2026Ahead of SpaceX earnings set to be released at 1600 ET (earnings call at 1630 ET), UBS analyst Christina Dwyer provided clients with color on what to look for ahead of earnings:SpaceX (SPCX) reports after the closing bell on Tuesday and heads into its first major earnings report as a public company with investor focus increasingly shifting beyond the quarter itself. While revenue and EBITDA performance will matter, the August 6 lockup expiration appears likely to be the bigger near-term driver, opening the door to the first meaningful wave of insider selling just days after results. On the call, management is expected to spend considerable time on AI-related initiatives. Investors will be looking for updates on data center buildouts, potential increases to compute targets and any incremental commentary around Grok deployment timelines. Stronger-than-expected AI revenue could represent one of the more credible upside catalysts. Beyond AI, attention will also center on Starlink and Starship. An updated Starlink subscriber figure could be disclosed, although the market may be hesitant to place significant weight on the metric while the network remains largely supported by V2 Mini satellites. For Starship, investors are likely to focus on execution milestones, launch cadence and any signals around the path toward operational payload launches. Positioning remains an important factor. Hedge funds still screen as notably short, which could amplify upside if AI revenue exceeds expectations or if Starlink economics surprise positively, particularly around ARPU. Even so, the desk believes the lockup expiration is likely to dominate the T+1 reaction and remain the primary stock-specific overhang in the near term.Polymarket odds of SpaceX beating on quarterly earnings currently stand around 35%.SPCX Short Hits 34% Of Float Ahead Of Earnings SpaceX's first earnings report since its record-setting early June IPO is just hours away and will test whether investors can justify the company's lofty valuation after a vicious post-IPO bear market.Shares hit a low of $104.83 on Monday, 22.4% below the $135 offering price and 53.5% beneath their June peak of $225, erasing more than $1 trillion in market value.
