Elon Musk's Gulfstream lands in Brownsville after SpaceX signs Terafab tax deal

Elon Musk's Gulfstream G650ER, tail N628TS, was tracked flying from Austin-Bergstrom International Airport to Brownsville South Padre Island International Airport on June 23, 2026, a 50-minute hop that touched down just after 2 p.m. local time.

If aboard, Elon Musk would arrive the same week SpaceX officially signed a tax agreement with Grimes County for the Terafab chipmaking joint venture, per a report from KBTX. The $20–25 billion Tesla-SpaceX-xAI project, unveiled in May, is planned for Austin and represents a rare convergence of Musk's three largest ventures under a single semiconductor supply chain. The flight also follows a Texas Supreme Court ruling on June 19 that rejected a bid to block beach closures for SpaceX launches, siding with the company and the General Land Office, as covered by the San Antonio Express-News.

The 50-minute flight is notably shorter than Musk's typical cross-country routes and fits a pattern of quick shuttles between his Austin-area operations and his Starbase home near Boca Chica. His fleet of five Gulfstreams has logged heavy activity in recent days, including a Seattle-to-Silicon Valley leg on June 22 and a Bay Area-to-Los Angeles hop the same day, suggesting a multi-stop week for an executive whose three largest ventures now share a single supply chain.
