First to $1 Trillion in Revenue: Amazon Wins the Race, and Walmart Pays Compounder Prices for Second Place

Two days after SpaceX's public listing, Elon Musk said his rocket company could bring in $1 trillion of revenue by 2030 — and that he would be "surprised if revenue is not greater than $1 trillion" in 2031. Before anyone argues about the promise, do the arithmetic on the facts both sides can sign: SpaceX reported about $18.7 billion of 2025 revenue and swung to a roughly $4.9 billion net loss for the year. Getting from $18.7 billion to $1 trillion in five years is a 53-fold increase, which works out to roughly 122 percent average annual growth, every single year, through 2030. That pace has never been sustained by any enterprise of comparable scale, and it matters that the company doing the promising carries a market value above $2 trillion on revenue one-fiftieth of that.

The analysts who model these numbers for a living have already made the contradicting call. Street forecasts put SpaceX 2030 revenue between $330 billion and $486 billion, with the most aggressive institutional figure — Evercore's, a large slice of it assumed AI-infrastructure revenue — landing at roughly half of Musk's target. So the useful question falls out of the milestone itself: if $1 trillion of annual revenue is the club to enter, which companies are actually on a defensible path to get there first? Two, and this is the telling part: both are public, both are almost deliberately boring next to a rocket company, and both are already past $700 billion in annual sales. They are Amazon and Walmart.

The shared record, before either side advocates: Amazon just knocked Walmart from the top spot on the Fortune 500, ending a 13-year streak at the top, after booking $716.9 billion of net sales in 2025 and $775.7 billion over the trailing twelve months through this year's second quarter — roughly 16 percent growth. Walmart reported $713.2 billion of total revenue for its fiscal year ended January 31, 2026, up 4.7 percent. No third contestant is within years: the next-largest American company, UnitedHealth, recorded about $448 billion of 2025 revenue, and even compounding at an aggressive 10 percent a year it does not cross $1 trillion until around 2035 — after both runners. The race to the milestone is between two firms, and it is not close.

The arrival math makes that clear. Amazon needs only 29 percent more revenue to reach $1 trillion; at the roughly 16 percent rate it is compounding today, its annual run rate crosses the line around 2028, and even if growth merely holds at 10 percent it lands on the milestone in 2029. Walmart needs 40 percent more revenue; at 5 percent growth that is roughly fiscal 2033, and even at a generous 7 percent it does not arrive before fiscal 2031. SpaceX, on the Street's own most optimistic 2030 figure of $486 billion, needs another six years of heroic 15 percent growth after that just to reach $1 trillion — call it the mid-2030s. The smallest company of the three is promising, on a revenue base 40 times smaller, to outpace both giants. It is not going to be first. The question is whether the market is paying the right price for the two that will be.

Round one goes to the fast claim. Amazon's bull case is not really about the milestone, which is nearly an afterthought of the compounding: revenue accelerated to up roughly 20 percent year over year in the latest quarter, mix keeps tilting toward higher-margin AWS and advertising, and operating margin sits at 11.5 percent — roughly two and a half times Walmart's. The bear side has to concede all of that and attack the price and the cash: Amazon has spent about $173 billion on capital over the past four quarters, roughly 22 percent of revenue, and trailing free cash flow has gone negative, near minus $12 billion, after a year of record investment. At roughly 3.7 times sales and about 40 times forward earnings, the price already embeds continued margin expansion on top of continued double-digit growth. Reverse-engineer it: the market is not paying for the $1 trillion badge, it is paying for the cash those revenues eventually convert into — and that cash has not shown up yet. The bull's answer is that the capex is buying the AI and data-center capacity that is the scarcest input in the economy right now. The bear's answer is that this is the first time in Amazon's history that betting this hard is mandatory rather than optional. Both statements are true; the disagreement is what they are worth.

Round two belongs to the slow claim, and it is the fight worth watching. Walmart's bull case rests on the fact that the only company besides Amazon with revenue north of $700 billion is also the one that converts sales into cash: free cash flow rose in fiscal 2026, the board authorized a fresh $30 billion buyback, U.S. e-commerce grew about 25 percent to $99.6 billion, global advertising revenue rose 46 percent, and net income grew about 10 percent on a 4.7 percent top line. That last gap is the whole Walmart story in miniature — per-share value compounding faster than sales, powered by margin-mix, digital, and buybacks. The bear's rebuttal starts where the bull's ends: Walmart trades at roughly $910 billion of market value and about 40 times forward earnings, the same multiple as Amazon, for one-third of Amazon's growth, and it sits at roughly 1.3 times sales versus Amazon's 3.7 times precisely because Walmart converts revenue into operating profit at 4.2 percent where Amazon does it at 11.5 percent. A mature retailer carrying a compounder's multiple is an anomaly on its face — Target, a comparable operator, trades near 16 times earnings. Add the uncomfortable fact that Walmart's operating margin actually fell last year, and the burden of proof sits entirely with the Walmart bull: the stock must keep grinding out mix-driven earnings growth for a decade to earn a multiple the market gave it in a few quarters.

The verdict has two parts, because the race and the investment are different questions. On the race, there is no contest: Amazon is the only company with a credible claim to $1 trillion in annual revenue before 2030, arriving around 2028; Walmart follows in the early 2030s; SpaceX, even on its own sell-side's numbers, does not arrive until the mid-2030s at best, which is the falsifiable version of the promise. On the price, the ruling is Amazon over Walmart — not because Amazon is cheap, because it is not, but because its roughly 40 times forward earnings buys three times the growth with improving margins, while Walmart's identical multiple buys 5 percent growth and a margin that just shrank. When two stocks that are racing to the same milestone trade at the same forward multiple, the one growing a third as fast is the one overpaying for the view.

Now the tripwires, because these judgments should have a shelf life. For Amazon, the single observation that breaks the case is free cash flow: if capital spending stays above 20 percent of revenue while growth slides below 10 percent and free cash flow remains negative by the next annual report, the 40-times multiple loses its anchor and the milestone itself becomes the whole thesis — a revenue trophy purchased with shareholder capital. For Walmart, the tripwire is the combination of growth and margin: if total revenue growth cannot hold above roughly 5 percent while operating margin keeps declining, the multiple has nowhere to go but down toward the 16 times that comparable retailers carry. Walmart reports its fiscal second quarter this morning, which makes that the first live test. For SpaceX, the check is simply the quarterly run rate against the ~122 percent path: every quarter that trails it quietly moves the 2030 date, and the Street's $330 to $486 billion envelope is the realistic floor of what to expect instead.

A headline is a milestone. A price is a wager. The companies that actually get to $1 trillion of revenue first are Amazon, then Walmart, and being first through the door is a trophy for the business — the question that pays is what an investor gives up to stand there and watch it happen. Amazon asks for its normal premium and is delivering an accelerating business. Walmart asks for Amazon's premium while delivering a five-percent grower. In this duel, the bull case with the weaker price is the one with the stronger argument to answer for.
