OpenAI reportedly needs to go public at a valuation of $1 trillion or extra. And no shareholder has extra driving on that quantity than Microsoft (NASDAQ: MSFT) — an organization having the worst 2026 of any “Magnificent Seven” member.
The pairing is unusual whenever you line it up. Microsoft shares are down about 19% this 12 months and sit almost 30% beneath their 52-week excessive. But the identical firm owns roughly 27% of what’s arguably probably the most worthwhile personal know-how corporations on the earth — a stake that would quickly carry a public price ticket.

So does the IPO math change the purchase case for a beaten-down Microsoft? Let’s run it.

The stake math
Begin with what Microsoft truly owns. When OpenAI accomplished its restructuring right into a public profit company final October, Microsoft disclosed that its funding represented roughly 27% of the corporate on an as-converted diluted foundation, valued at roughly $135 billion. The identical settlement prolonged Microsoft’s rights to OpenAI’s know-how by means of 2032 and included a dedication from OpenAI to buy an extra $250 billion of Azure providers.
Then got here June. OpenAI confirmed it had filed confidential paperwork with the Securities and Alternate Fee for an preliminary public providing (IPO), the primary formal step towards an inventory. And based on reporting from The New York Occasions, the corporate is now leaning towards a 2027 debut fairly than late 2026 — largely as a result of CEO Sam Altman has reportedly refused to simply accept a valuation beneath $1 trillion.
Here is the mathematics that issues for Microsoft shareholders. If OpenAI lists at $1 trillion, a 27% stake could be value about $270 billion — roughly double the worth implied when the deal was struck, and equal to about 9% of Microsoft’s whole $2.9 trillion market capitalization.
Some caveats, nevertheless, belong subsequent to that determine.
The IPO timing and value are rumored intentions, not commitments. OpenAI will seemingly maintain elevating capital, which might dilute the proportion over time — the 27% determine already displays dilution from OpenAI’s latest funding rounds. And an inventory would not hand Microsoft money. It could hand it a visual, liquid value for one thing the market at present values with a shrug.
That final level is the chance. Buried inside 2026’s worst-performing mega cap sits an asset that might be value almost a tenth of the corporate’s market worth, and an IPO would pressure buyers to lastly value it.
In the meantime, the precise enterprise
The majority of the long-term funding case for Microsoft inventory does not relaxation on OpenAI, although. As an alternative, it rests on the underlying enterprise. And the enterprise has continued to carry out nicely whereas its share value hasn’t.
In its fiscal third quarter (ended March 31, 2026), Microsoft’s income rose 18% 12 months over 12 months to $82.9 billion, earnings per share climbed 23% to $4.27, and Azure and different cloud providers income grew 40%. For a enterprise of Azure’s scale, that is a rare charge.
The inventory’s downside is what that progress prices. Microsoft expects about $190 billion in capital expenditures in 2026, and administration mentioned that determine contains roughly $25 billion simply from larger part costs, with reminiscence chips caught in a world provide crunch. Traders have spent the 12 months worrying that spending of that magnitude will weigh on margins for years earlier than it pays off, and so they have repriced the inventory accordingly.
That repricing, nevertheless, is what makes the shares fascinating now. Microsoft trades at about 23 instances earnings and roughly 20 instances ahead earnings — a reduction to the premium it commanded all through many of the synthetic intelligence (AI) growth, whilst the corporate nonetheless compounds income at 18%.
So, the place does that depart the inventory?
I feel it is a purchase. With Azure rising at a 40% year-over-year charge, even because the inventory trades at simply 20 instances its ahead earnings, it appears to be like enticing even with out contemplating its OpenAI funding. A possible OpenAI IPO is arguably simply icing on the cake; a $1 trillion debut would put a public quantity on a stake the market has been ignoring.
Nonetheless, that $190 billion of spending has to earn its maintain, and OpenAI’s web losses already stream by means of to Microsoft’s outcomes (although the corporate’s personal non-GAAP figures particularly strip that affect out). However at this value, with this progress, buyers are arguably being compensated for the wait.
