SpaceX & the ETFs: A Matter of Weight & Wallets

It appears that Elon Musk’s SpaceX1 is contemplating a public offering, or ‘IPO’ as the scribes in the Guild of Alchemists and Venture Capitalists insist on calling it. A rather dramatic event, if it transpires. The rumours suggest a raising of capital in the region of 50 billion units of currency – a sum that would make even the most seasoned dwarven treasurer blink. And a valuation… well, a valuation that threatens to destabilize the very concept of ‘market capitalization’ itself. We’re talking about potentially 1.5 trillion units, which, if you’ll permit a moment of comparative accounting, is roughly equivalent to the combined wealth of several moderately sized kingdoms… and a very enthusiastic collection of gnomes.

The implications, naturally, extend beyond mere numbers on a ledger. It’s a ripple effect, a disturbance in the Force… or, more prosaically, a significant adjustment to the weighting within certain Exchange Traded Funds, or ‘ETFs’ as the modern oracles pronounce them. And that, my friends, is where things get… interesting.

SpaceX, the S&P 500, and the Art of Index Inclusion

Age, it seems, is no barrier to entry into the hallowed halls of the S&P 5002. Which is just as well, considering some of the institutions that have managed to gain admittance over the centuries. The usual criteria apply: domicile within this realm, trading on a recognized exchange (preferably one that doesn’t involve too much haggling with dragons), four consecutive quarters of… let’s call it ‘positive fiscal enchantment’, and a minimum market capitalization of 22.7 billion units. SpaceX, by all accounts, ticks all the boxes.

Indeed, the S&P Dow Jones Indices – the custodians of this particular index of importance – are reportedly considering a relaxation of the rules to expedite SpaceX’s inclusion. A move that has raised eyebrows amongst the more conservative members of the Guild, who maintain that tradition is a vital bulwark against… well, against everything, really. But, pragmatism, as always, tends to win out.

If this comes to pass, the usual suspects – the Vanguard S&P 500 ETF (VOO), the iShares Core S&P 500 ETF (IVV), and the State Street SPDR S&P 500 ETF (SPY) – will find themselves suddenly burdened with a rather substantial holding of SpaceX shares. These, as any self-respecting market mage will tell you, are currently the three largest ETFs trading in this realm. A considerable responsibility, to be sure.

Size Matters: The Weight of a Rocket in a Portfolio

The potential rule changes aren’t merely a matter of administrative convenience. It’s the sheer weight that SpaceX could exert within the index that’s causing a stir. If SpaceX were to appear on the market today with a valuation of 1.5 trillion units, it would, theoretically, surpass even Tesla3, Musk’s other… endeavour. A rather amusing thought, when you consider the rivalry between the two companies. It would also, rather dramatically, displace Berkshire Hathaway from the top ten holdings of the index. A fate that few predicted for the venerable investment conglomerate.

And let us not forget the inevitable consequence: when SpaceX joins the S&P 500, all the active and index funds that track the index will be compelled to purchase the stock. A surge in demand that could, shall we say, provide a rather… spirited short-term boost. The market, of course, rarely behaves rationally, but it does have a peculiar fondness for spectacle.

1 SpaceX, officially ‘Space Exploration Technologies Corp.’, is a company dedicated to the reduction of the cost of space access. Or, as the alchemists would have it, the creation of increasingly elaborate methods of escaping the mundane.
2 The S&P 500 is a stock market index representing the performance of 500 large-cap companies in the United States. It is often considered a benchmark for the overall health of the American economy. Or, at least, that’s what the economists tell us.
3 Tesla, a manufacturer of electric vehicles and energy storage systems. Also known for its charismatic, if occasionally unpredictable, CEO.
