With companies both great and small doing their best to move into the cannabis marketplace, this article on Amazon, medical marijuana and more, had us chatting around the ol’ MMLG water cooler. Namely, we got to wondering: when will the massive corporations make their forays into the cannabis marketplace?

The move will surely be in the medical marijuana marketplace before any of these giants take the bold step into adult-use. But who will be firs? Amazon is as good a guess as any, what with the online-retail behemoth’s built-in delivery system and its massive healthcare partnership program with Berkshire Hathaway and JPMorgan Chase.

Then again, Google/Alphabet and GV (Google Ventures), have been steadily investing in medical start-ups since GV came into existence back in the late ’00s. The portfolio of healthcare start-ups they’ve invested in is now up to 60, and while many of those ventures are shoulders-deep into researching cures and breakthrough treatments for scourges such as cancer, Alzheimers and Parkinson’s, medicinal cannabis is tucked into some of those companies’ start-up kernels as well. Toss in the consideration that Google, while not on an Amazonian scale of delivery infrastructure, does pretty good with its Google Express service. Oh, and they happen to have a health section ready-made for medicine and prescriptions.

Another possibly surprising consideration in this burgeoning arms-race? Walmart. The Arkansas-based retail giant has taken a backseat to Amazon in the headlines, but don’t bet against the Walton family yet. Walmart entered into a distribution partnership with American Cannabis Company out of Denver earlier this year. Walmart, as you may have guessed, not only does “okay” with its pharmacy and prescription services, but they also run a very reputable delivery program for prescriptions. Additionally, Walmart purchased ecommerce hub, Jet.com, back in 2016 to better compete with Amazon’s ecommerce juggernaut.

The common features all of these companies bring is clear: massive infrastructural know-how, bandwidth for days, delivery and retail (online and off) expertise that is second to none, reams of consumer data, and gobs upon gobs of money. Just massive, obscene piles of money.

Of course, the unspoken fear is that maybe these companies will first go to Canada. After all, Canadian-owned Cronos was the first cannabis company to be listed on the NASDAQ back in February. Amazon and Walmart, with their established and very strong presence in Canadian retail could make our neighbors to the North an opportune test market. Consider for a second, too, that Canada’s going fully legal this fall, while markets within the United States are stalled, and you don’t have to squint too hard to see the writing on the wall.
