On Wall Street, there’s a specific type of week when a story changes more quickly than the analysts can keep up, and the middle of April had that exact texture. Three weeks prior, the majority of North American investors were unaware of Xanadu Quantum Technologies, a Toronto-based photonic quantum computing company, but it quickly rose to prominence as one of the Nasdaq’s loudest tickers. It wasn’t a launch of a product. It wasn’t a beat in earnings. Nearly all of the push came from Nvidia.
In reality, Nvidia’s actions were modest in scope but profoundly symbolic. In order to assist researchers in fixing the mistakes that affect every quantum computing operation, the company released an open-source family of AI models known as Ising. There was no formal partnership announcement, no contract, and no investment in Xanadu. The market responded as though Nvidia’s simple gesture toward quantum computing as a viable, near-term frontier was an endorsement. Investors appear to think that a sector is about to become significant when Jensen Huang’s company highlights it.

That week, Xanadu’s stock chart resembled a cartoon. Shares increased by 17%, 28%, 29%, and 70% in a single session after closing at $7.65 on Thursday. This was enough to cause a brief halt on the Toronto Stock Exchange. The company’s market capitalization was approximately $7.5 billion by Wednesday’s close, and it momentarily exceeded $16 billion. For a business that only made $4.6 million in sales the previous year, the figures had that certain optimism that always leads to doubts.
The founder, Christian Weedbrook, has an unusual life story for someone who currently has about $1.5 billion in paper wealth. He left film school to pursue a career in physics and eventually founded a business that performs quantum computation using light passing through fiber-optic cables. According to reports, he has stated that he doesn’t give the stock price much thought. This is the kind of statement founders make when the stock is rising and conveniently change when it isn’t. It’s difficult to ignore how rapidly the storyline changed from “obscure Canadian SPAC” to “the next big thing in computing” as you watch the coverage develop.

Quietly, other early backers profited. About 40.2 million Xanadu shares are held by OMERS, the Ontario municipal pension fund that made the well-known early wager on Shopify. This position was momentarily valued at $1 billion. Suddenly, Georgian Partners’ Fund IV, which raised $550 million in 2018, had a stake large enough to be considered a fund-maker by venture capitalists. When nothing in the portfolio appears to be working, these are the times that justify the protracted, gradual losses of the interim years.
However, the rally seems to be ahead of the science. The quantum group, according to Wedbush analysts, is like a coiled spring that is oversold for months before snapping forward at the slightest positive signal. There are still unanswered questions regarding the scalability of photonic systems, the commercial timeliness of error correction, and Xanadu’s ability to construct the 2030 data center it mentions. Years ago, both Nvidia and Tesla encountered similar skepticism. A few of these wagers are profitable. Some people don’t. Although it’s still unclear what category Xanadu will fall into, the market has chosen to find out the costly way for the time being.
