Meanwhile, tech giant Alphabet's (GOOG, GOOGL) CEO Sundar Pichai spent the week promoting Google's latest AI model, while Amazon (AMZN) CEO Andy Jassy was largely missing from commentary.
"Turns out the future does have flying cars."
– Elon Musk, CEO, SpaceX/Tesla, after the Roadster reveal
Musk's long-awaited Roadster demonstration was broadcast as a joint Tesla-SpaceX event. "Well, it worked," he said, after the car's most dramatic moment came when it used thrusters to land after an inverted jump.
The demonstration drew investor attention and focus towards the engineering that went into its creation, but its commercial viability remains less clear. Investor Gene Munster called it an "engineering flex" with no commercial value, while suggesting the event might be another hint at a potential SpaceX and Tesla merger.
Tesla says Roadster production will begin in 2028. However, Musk has acknowledged that the car will not materially move the company's revenue. Tesla's earnings report, slated to land next week, will provide a more direct look at the business behind the spectacle.
On Stocktwits, retail sentiment behind TSLA stock slipped to 'bearish' from 'neutral' territory over the past week. Platform data showed chatter increasing by nearly 150% in the last seven days..
– Elon Musk, CEO, SpaceX/Tesla, on Grok Bot purchase errors
Musk continued to stay active on X. Responding to a user whose flight Grok Bot had booked using an image of a payment card, he said SpaceX would reimburse users if the bot made an incorrect purchase or exposed their card details.
The pledge came after SpaceX Super Intelligence introduced a single subscription combining Grok, Grok Bot, Cursor and X Premium earlier in the week.
"Maybe we should start a competitor to Amazon."
– Elon Musk, CEO, SpaceX/Tesla, on Grok Bot purchase errors
Musk also floated the idea of starting a competitor to Amazon after e-commerce giant blocked Grok Bot from making purchases on its platform. This marks a rare instance of a Magnificent Seven CEO publicly floating a rival to its peer so publicly.
"Old friends are the best friends. Jensen rocks."
– Elon Musk, CEO, SpaceX/Tesla, on Nvidia CEO comments during interview
Musk's praise for Huang allowed the Nvidia CEO's remarks on a BG2 podcast, where he said that Nvidia now counts SpaceX alongside its cloud provider customers, and that the two companies' engineers are designing a new kind of server for space and Earth.
Musk said Star Mind, which SpaceX is co-engineering with Nvidia, is "far better than almost anyone expects" and will reach volume production next year. Working with Nvidia's engineers, he added, "is pure joy!"
"Nobody knows more about energy than he does."
– Jensen Huang, CEO, Nvidia, on Elon Musk, on BG2 Pod podcast
On the B2G podcast, Huang said Nvidia used to count Musk's companies as enterprise customers and now counts them alongside its cloud service providers. He added that the demand for Grok Bot is "really skyrocketing."
Huang also noted that Musk loves the intersection of computing and physical build-outs. He then said the two companies will explore "putting data centers out in space" together, with their engineering teams working closely on a new type of server architecture that "might be super good" both in orbit and on Earth.
"We absolutely should work with each other so that we advance the technology safely."
Huang travelled to Europe this week, and told the press that the U.S. and China need to work together and maintain dialogue to ensure the "potentially dangerous" technology develops safely.
According to him, the AI trade remains strong. Speaking at an event in Stockholm, Huang expressed confidence in CoreWeave's operational trajectory despite intense scrutiny from credit markets and equity investors. "CoreWeave's strength is improving every day," Huang said. "I'm optimistic. Their cost of capital is actually decreasing."
On Stocktwits, retail sentiment around NVDA stock continued to trend in 'bearish' territory over the past week. Platform data showed chatter increasing by only 14% in the last seven days.
"Personal superintelligence for everyone."
– Mark Zuckerberg, CEO, META, on Threads announcing Muse Wonder
Zuckerberg used the launch of Muse Wonder to focus on his consumer-focused vision for AI. Meta said the new models were trained in its Prometheus gigawatt data center and underpin its model API and Muse Code agent.
The company's pitch also draws a distinction between its approach and competitors' priorities. Zuckerberg said Meta was "much more focused on personal empowerment" than knowledge-work automation.
On Stocktwits, retail sentiment around META stock continued to trend in 'bearish' territory over the past week. Platform data showed chatter dropping by 7% in the last seven days.
"We must assume a model is compromised and contain it from the start."
– Satya Nadella, CEO, Microsoft in a post titled "Models as Insider Risks in the Super Intelligence Era" on X
Nadella's post continued to shape the week's discussion about AI security. He argued that companies should treat AI models as potential insider risks, rather than assume they will behave safely once deployed.
His suggestion was to "separate the supply of intelligence from the authority over it." He also said an authorized person should always be able to "pause or shut down a model mid-task."
On Stocktwits, retail sentiment around MSFT stock shifted to 'bearish' from 'neutral' territory over the past week. Platform data showed chatter dropping by 43% in the last seven days.
John Ternus, CEO, Apple to TIME, discussing earlier foldable phones
Ternus, in an interview with TIME, said Apple's approach to product design, included waiting before entering categories where competing products were already available.
According to him, Apple's approach is based around prioritization rather than simply criticizing rivals. "You can't do everything," he said, adding that the company concentrates on what matters most. Apple's iPhone Duo is slated to launch next week.
"All options should be on the table."
John Ternus, CEO, Apple to CNBC, on reports that Apple tested Chinese chips
Ternus this week also addressed reports that Apple had tested chips from China, saying that "all options should be on the table." The comment came during a wider discussion of the iPhone Duo, memory shortages and AI.
On Stocktwits, retail sentiment around AAPL stock saw the largest shift, dropping to 'extremely bearish' from 'neutral' territory over the past week. However, platform data showed chatter rose dropping by 13% in the last seven days.
Pichai this week announced the expansion of Gemini 4 Argon beyond cybersecurity specialists to enterprise customers and Pro and Ultra subscribers. Introductory pricing was set at $2 and $10 per million tokens through November 30.
The rollout comes amid efforts by Google to strengthen its position in the AI market following delays, the abandonment of Gemini 3.5 Pro.
Google Quantum AI achieved a milestone this week by demonstrating magic state cultivation on its Willow quantum processor, reducing quantum computing errors by 40 times.
Pichai also reacted to Musk's Roadster demonstration. "The FSD version of this will be something," he wrote on X. Alphabet owns Waymo, which operates in autonomous driving as a competitor to Tesla.
Retail sentiment around GOOGL stock on Stocktwits flipped to 'bearish' from the 'bullish' zone over the past week. Chatter also dropped with platform data showing an over 37% decrease in message volumes.
There were no new remarks from Jassy this week. However, a spokesperson for the company did address the controversy with Musk's Grok Bot. They said third-party shopping apps should "operate openly and respect service provider decisions."
Like GOOGL shares, AMZN stock also saw retail sentiment on Stocktwits flip to 'bearish' from 'bullish' territory over the past week, alongside a 17% increase in chatter.
