Cathie Wood Touts $50 Billion Investment

Investor Cathie Wood-led ARK Invest shared its insight into the future of humanoid robots and AI, saying that the technology should “create new jobs” rather than replace existing ones, but added that new technologies always coincide with fears about job losses, citing the emergence of the Internet as an example.

“US labor productivity has compounded at ~2.1% annually since the commercial tractor’s debut. Real disposable income has grown at a ~3.2% annualized rate over the postwar period,” the post said, adding that the sector could grow “meaningfully” within the next decade.

Ark then said there was a caveat in the form of the intricate and complex nature of humanoid robots. “A humanoid robot is 200,000 times more complex than a robotaxi,” Ark said.

The firm also said that an investment of approximately $50 billion in compute was needed to help the technology reach “human-level task proficiency.”

“Tesla’s Optimus could approach that threshold around 2028. China is pushing hard to get there first,” Ark said, backing Optimus.

AI Job Losses

Microsoft Corp cut 4,800 jobs, or 2.1% of its global workforce across teams in its organization. Of the 4,800 cuts, over 3,200 will comprise Xbox employees. Xbox will reportedly cut 1,600 jobs immediately and another 1,600 over the next year. The move has sparked fears of AI-induced job losses.

Sen. Elizabeth Warren (D-Mass.) has also warned about AI causing job losses, following Oracle Corp‘s announcement that it had cut 21,000 employees over the past year due to AI, among other reasons.

Building Wealth Across More Than Just the Market

Building a resilient portfolio means thinking beyond a single asset or market trend. Economic cycles shift, sectors rise and fall, and no one investment performs well in every environment. That’s why many investors look to diversify with platforms that provide access to real estate, fixed-income opportunities, precious metals, and even self-directed retirement accounts. By spreading exposure across multiple asset classes, it becomes easier to manage risk, capture steady returns, and create long-term wealth that isn’t tied to the fortunes of just one company or industry.

Arrived

Backed by Jeff Bezos, Arrived Homes makes real estate investing accessible with a low barrier to entry. Investors can buy fractional shares of single-family rentals and vacation homes starting with as little as $100. This allows everyday investors to diversify into real estate, collect rental income, and build long-term wealth without needing to manage properties directly.

FarmTogether

Farmland has historically held its value through market volatility and delivered returns uncorrelated to stocks and bonds. For accredited investors, FarmTogether offers direct access to high-quality U.S. farmland starting at $15,000 — fully managed, with no landlord headaches.

Immersed

Immersed is building technology for the future of work through spatial computing. Known for its AR/VR productivity platform that enables users to work across multiple virtual screens, the company has grown to more than 1.5 million users worldwide. Immersed is also developing Visor, a lightweight headset designed specifically for professional productivity, positioning the company at the intersection of remote work, extended reality (XR), and next-generation computing.

Private real estate and private credit can add income and stability to a stock-heavy portfolio. Fundrise offers access to diversified private real estate and credit strategies through an easy-to-use platform, with professionally managed portfolios designed to generate passive income and long-term growth.

Realberry

Institutional-quality real estate has traditionally been difficult for individual investors to access. Realberry gives accredited investors direct access to private real estate opportunities backed by a team with 35 years of experience, $3.4 billion in assets under management, and $481 million in cumulative distributions paid to investors as of Q4 2025, according to the company. With a portfolio spanning 13 million square feet across seven U.S. states, Realberry focuses on acquiring, developing, and managing real estate with an emphasis on long-term value creation while its principals often invest alongside clients to help align interests.

BluSky AI

The rapid adoption of artificial intelligence is creating significant demand for data centers, power, and compute infrastructure. BluSky AI is building modular AI data centers designed to support next-generation AI workloads while aiming to reduce deployment timelines compared to traditional facilities. For investors looking beyond AI software and applications, the company offers exposure to the infrastructure layer that makes artificial intelligence possible.

Mode Mobile

Mode Mobile is changing the way people interact with their phones by letting users earn money from the same apps and activities they already use every day. Instead of platforms keeping all the advertising revenue, Mode Mobile shares a portion back with users who engage with content, play games, and scroll on their devices. Named one of Deloitte’s fastest-growing software companies in North America, the company has built a large beta user base and is scaling a model that turns everyday smartphone usage into a potential income stream.
