The Return of Moonshot Investing: Why Deep Tech is Defying High Interest Rates

The financial markets of mid-2026 are currently defined by a striking contradiction that is baffling traditional economists and portfolio managers alike. On one hand, the Federal Reserve is maintaining highly restrictive interest rates to combat stubborn inflation, creating a punishing environment for corporate borrowing. This dynamic will take center stage this week as Kevin Warsh gavels open his first Federal Open Market Committee (FOMC) meeting as Fed Chair. With U.S. inflation running at a three-year high of 4.2%, the central bank is widely expected to hold the federal funds rate steady at a restrictive 3.50% to 3.75%.[2][7]

Yet, on the other hand, investors are pouring unprecedented sums of capital into the most expensive, speculative, and futuristic projects on the planet, completely defying the standard macroeconomic playbook. Historically, high borrowing costs are considered highly toxic for "moonshot" companies—startups that require billions of dollars in upfront capital and years of intensive research before generating a single dollar of profit. When money is expensive, investors typically retreat to safe, cash-flowing assets. Yet, the current appetite for transformative "deep tech" appears entirely immune to the macroeconomic gravity that normally grounds it.[1][7]

The ultimate proof of this resilience is SpaceX. The aerospace giant is currently executing what is expected to be the largest initial public offering in history, targeting a staggering valuation of approximately $1.75 trillion. This public listing is serving as a massive stress test for the market's willingness to fund capital-intensive innovation in a high-rate environment. To put that $1.75 trillion figure in perspective, SpaceX's valuation has more than doubled in just six months, climbing rapidly from an $800 billion private tender offer that cleared in December 2025.[3][6]

A major driver of this premium was the unprecedented February 2026 merger between SpaceX and Elon Musk's artificial intelligence startup, xAI. By absorbing xAI, SpaceX effectively combined its orbital satellite infrastructure with advanced AI compute capabilities, creating a vertically integrated behemoth valued at $1.25 trillion at the time of the merger. This strategic move signaled to the broader market that the future of technology requires massive physical infrastructure, not just clever software algorithms. By bringing AI hardware and space logistics under one roof, the merger fundamentally altered how institutional investors value deep tech assets, proving that the next trillion-dollar opportunities lie in controlling the physical layer of the internet and compute.[6][7]

This mega-merger highlights a broader structural shift currently sweeping through venture capital: the aggressive transition from software-as-a-service (SaaS) to physical infrastructure. For the past decade, investors heavily favored software companies because they were relatively cheap to scale, required minimal physical assets, and offered rapid returns on investment. A small team with laptops could build a billion-dollar SaaS company in a matter of years. Today, however, industry insiders are warning of a "SaaSpocalypse," arguing that pure software has hollowed out its own value in an era where generative AI can write code and automate digital workflows instantly.[4][7]

Instead, the frontier of innovation has decisively shifted to deep tech—the physical substrate that powers the next generation of computing, energy, and aerospace. Investors are realizing that without advanced hardware, the software revolution simply cannot proceed. "If we don't invest in the deep tech that powers AI—the physical substrate—the whole AI project hits a wall," noted Mahir Sahin, a former Google executive who recently launched a €50 million deep tech fund, Cloudberry Ventures, in Europe. His fund is specifically targeting industrial infrastructure, compute hardware, and advanced materials to break through current technological bottlenecks.[4]

This sentiment is echoing globally across the investment landscape, from Silicon Valley to European financial capitals. In Canada, the National Angel Capital Organization recently unveiled its largest-ever cohort of "Moonshot Ventures," a group heavily weighted toward artificial intelligence hardware, quantum computing, and advanced robotics. These emerging companies are not building consumer apps or social networks; they are developing critical technologies for defense sovereignty, energy security, and industrial automation. This reflects a concerted national effort to build sovereign capabilities in future-defining industries, ensuring that domestic markets are not entirely reliant on foreign hardware for their critical infrastructure and national defense.[5][7]

The capital requirements for these deep tech sectors are absolutely staggering, which makes their continued success and funding in a high-interest-rate environment all the more remarkable. Building a quantum computer, a next-generation photonics radar system, or a reusable orbital rocket requires specialized laboratories, rare materials, and years of iterative testing before a commercially viable product ever emerges. Analysts point to several unique factors driving this market anomaly and keeping the capital flowing into these capital-intensive projects despite the Federal Reserve's highly restrictive monetary policies.[1][7]

First, sovereign wealth funds and government initiatives are increasingly stepping in to subsidize critical industries, viewing deep tech not merely as a financial investment, but as a matter of urgent national security. Governments recognize that leadership in quantum computing, advanced materials, and orbital infrastructure will dictate geopolitical power over the next century. Programs like Canada's National Quantum Strategy, alongside various defense innovation funds across North America and Europe, are deploying massive amounts of capital to ensure domestic startups can scale. By treating these investments as strategic imperatives rather than pure financial plays, governments are effectively insulating the deep tech sector from the broader macroeconomic headwinds caused by the Federal Reserve's current interest rate policies.[5][7]

Second, the sheer scale of the artificial intelligence boom has forced a physical reckoning across the entire technology industry. AI models require massive, energy-hungry data centers to train and operate, which in turn require next-generation energy grids, advanced cooling materials, and cutting-edge silicon chips. The realization that artificial intelligence is fundamentally constrained by physical infrastructure has triggered a massive gold rush into the hardware and energy sectors. Investors are scrambling to fund the picks and shovels of the AI revolution, knowing that whoever controls the power generation, the cooling systems, and the semiconductor manufacturing will ultimately capture the lion's share of the value generated by the software layer.[4][6][7]

As SpaceX transitions to public markets with its integrated AI and space infrastructure, it will serve as the ultimate bellwether for retail and institutional appetite for this new wave of deep tech. The success of this IPO will provide critical data on whether everyday investors are willing to underwrite the massive capital expenditures required to build the future. If public markets eagerly absorb a $1.75 trillion company built on orbital rockets and AI data centers, it will validate the thesis that true technological leaps can transcend restrictive monetary policy. It would prove that everyday retail investors and massive institutional funds alike are still willing to fund ambitious moonshots, provided the potential payoff is a fundamental rewiring of the global economy and human capability.[1][3][7]

However, significant risks remain for the broader innovation ecosystem. If the Federal Reserve's "higher for longer" stance persists well into 2027, the wider landscape of smaller deep tech startups may eventually find their funding pipelines running dry. While mega-cap giants like SpaceX can command unlimited capital and easily absorb smaller players—as seen with the xAI merger—the next generation of independent hardware innovators may struggle to survive the macroeconomic gravity. This dynamic could leave the future of deep tech entirely in the hands of a few well-funded titans, fundamentally reshaping the competitive landscape of global innovation and raising questions about monopolistic control over the physical infrastructure of tomorrow.[2][7]
