SpaceX has reshuffled senior leadership in its data center construction team, replacing several managers with people mainly drawn from its rocket and satellite internet businesses. According to Sina Finance, people familiar with the matter said the move followed persistent civil engineering and operational reliability problems at existing data center facilities in Tennessee and Mississippi. SpaceX's AI unit, SpaceXAI, had prioritized speed in the early construction phase, and some facilities lacked backup cooling and power systems for months, increasing outage risk. Former Falcon rocket and Dragon spacecraft production vice president Wesley Salandro and Starbase launch site product support operations director Logan McConnell have joined the AI infrastructure team, while SpaceX has also brought in an engineer from Neuralink to help with civil engineering and continues hiring for related roles. Several core members of the data center team have recently left, including Jake Palmer, who handled physical infrastructure and departed at the end of July after joining in September 2025, as well as Zach Wells and Pablo Mendoza. Brent Mayo previously left for OpenAI, and Liz Balke, who joined from Tesla's Dojo supercomputer project, has moved to Anthropic. The personnel turnover has also increased uncertainty over the timetable for new data center construction. Beyond the Memphis hub, expansion plans in Texas and other locations have been delayed multiple times. Even so, SpaceX still views rapid construction and cost advantages as a core competitive strength ahead of its June IPO and plans to keep investing heavily in AI infrastructure. As of June, its online computing capacity was about 1.4 gigawatts, is expected to exceed 2 gigawatts by year-end, and Musk said it would rise sharply by the end of 2027.

According to Jin10, The Information reported that Elon Musk has reshuffled the team responsible for SpaceX's data center construction in recent weeks, replacing several leaders and moving executives from its rocket and satellite internet businesses to strengthen data center infrastructure.

According to CNBC, Evercore ISI upgraded Duolingo to outperform from in line and raised its price target to $210 from $105, implying nearly 42% upside from Monday's close. Analyst Mark Mahaney said the language-learning app now has about four times the selection of its closest pure-play competitor and cited survey data showing daily usage rising from 61% in '25 to 65% in '26, along with higher satisfaction, as evidence that recent AI-linked product changes are helping. Duolingo shares were last up more than 5% on Tuesday after falling more than 10% year to date and about 15% in 2026. Evercore said AI-enabled products including spoken tokens, Flashcards and Speaking Adventures should help the company attract more users and improve monetization, and Mahaney said Duolingo's current user retention rate recently hit a record 84%, up about 1% year over year. He also said generative AI tools are unlikely to hurt Duolingo because ChatGPT users are mainly interested in language learning for travel, a segment Duolingo is less focused on because it is harder to monetize.
