The bull case for Elon Musk's constellation of companies has usually been told one ticker at a time — Tesla for autos, SpaceX for rockets, Starlink for broadband. Eva Ados, chief operating officer at ERShares and an early SpaceX investor, is making a different argument. She thinks the whole empire should be valued as a single supply chain, and the closest historical comparison is John D. Rockefeller.
Ados laid out the case on CNBC while defending ER Shares' aggressive SpaceX weighting in its XOVR ETF, the first fund to bring private-company exposure to retail investors. Pressed by hosts on the so-called key person risk of so much wealth concentrated under one founder, Ados flipped the framing. "I think it's actually to the benefit because now he owns the whole supply chain," she said. "Just like Rockefeller, he owns everything linked together. So his competitors are going to be to be using him in order to put rockets up in the space. So once you get to that point, then you kind of having have a monopoly."
The Rockefeller comparison is provocative but rooted in specifics. In the late 19th century, Standard Oil built its moat not by dominating any single step in the oil business but by controlling the pipelines, refineries and railroads in a single vertical stack. Competitors could drill, but they could not get their barrels to market on favourable terms without Rockefeller's permission. Ados argues Musk is assembling an analogous structure across space, communications and compute, with SpaceX as the load-bearing piece.
"It is the mode. It's one of the very few companies globally that actually has a mode and it has a mode a very well diversified mode across many industries space AI telecom and think about it when Amazon is launching Amazon Leo and the in order for them to meet the FCC deadline they need to use SpaceX," she said. "When you make your biggest competitor your biggest customer that is a real mode."
That Amazon example is the cleanest illustration of the thesis. Amazon's Project Kuiper — marketed as Amazon Leo — was designed to compete head-on with Starlink. Kuiper's FCC license comes with deployment deadlines Amazon cannot meet using its chosen launch partners at current cadences, forcing the company to book launches on Falcon 9 rockets operated by the competitor it is trying to displace. The revenue SpaceX earns from those launches is profit; the strategic intelligence it accrues by handling rival payloads is something harder to price.
The same dynamic plays out across telecom. Starlink's satellite broadband reach means traditional terrestrial operators need to partner with SpaceX to offer direct-to-cell service in remote coverage gaps. In AI, the compute capacity xAI is pulling together, combined with Tesla's data collection from a real-world autonomous fleet, creates another vertical stack where Musk-owned businesses are becoming the upstream supply. In each case, rivals don't just compete with a Musk company; they pay one.
Sceptics argue the comparison is strained. Rockefeller's Standard Oil was broken up under the Sherman Antitrust Act precisely because its supply chain control became indistinguishable from market abuse. A Musk supply chain with similar characteristics could ultimately invite similar regulatory response, particularly in a second Trump administration that has shown willingness to use antitrust selectively. Ados does not address that risk directly — her argument is about the investment opportunity, not the political one.
For ERShares, the thesis translates into portfolio concentration. Ados has previously described SpaceX as the single best investment in the entire investable universe and called its upcoming IPO the biggest opportunity of the last decade. Those are extraordinary statements by institutional-investor standards, and they only make sense if you accept the broader framing that Musk's companies should be analysed as an interconnected system rather than as a collection of standalone bets.
Whether that framing holds up as SpaceX approaches its IPO will be the real test. A listed SpaceX will be valued by public markets on its standalone financials. Ados is betting that the supply chain effect — the Rockefeller effect, as she puts it — will show up in those numbers fast enough to justify the weighting.
