OpenAI shares are buying houses in San Francisco. That’s the news. What happens next is the question nobody has answered yet.
The viral text message — a founder losing a Noe Valley bid despite offering hundreds of thousands over asking — exposed a market where pre-IPO stock beats cash. The seller picked OpenAI equity instead.
Kevin O’Connor, an associate broker with Sotheby’s, confirmed he sees this happening more and more around the Bay Area. “I think the motivation is to get the jump on things,” he said. But getting the jump on things means jumping into uncharted territory.
Tax bills, for one. Ahmed Banafa, a tech expert at San Jose State University, warned that stock values could drop once companies go public.
That leaves sellers holding shares worth less than they paid for the house — and an outsized tax bill on the original transaction price. The IRS does not care that your OpenAI stock tanked. It cares what the shares were worth the day you signed.
Nobody is talking about what happens when the music stops. Banafa sees upside too. “They trust that this company is a good company and that this company is a company that can deliver based on everything they’ve heard about it,” he said.
Trust is the whole game. There is no prospectus on pre-IPO shares.
No SEC filing. No quarterly earnings call. Just belief that the AI boom keeps booming.
That belief is now pricing out cash buyers. Families watching from Asia, where the AI sector draws intense investor attention, are seeing a market where a startup founder’s paper wealth trumps a doctor’s savings.
The viral text made that plain. O’Connor says the motivation is speed. Sellers want in on AI’s growth.
They want equity in companies they think will only appreciate. But equity cuts both ways. If OpenAI’s valuation wobbles — if a competitor ships a better model, if regulation hits, if the hype cycle turns — the seller’s new nest egg cracks.
There is no FDIC insurance on founder shares. Banafa noted another angle.
“That’s going to increase the value for the companies, because now the shares of the company are used as a currency.” Currency needs stability. Pre-IPO stock is the opposite of stable. It is illiquid, hard to price, and taxable at the moment of exchange.
A seller who takes OpenAI shares today might find themselves liquidating at a loss to pay the property tax next year. Realtors are not issuing warnings.
They are closing deals. The brokerages that handle these transactions — Sotheby’s among them — are adapting to a new payment method without new safeguards. There is no standard contract clause for share transfers.
No escrow procedure. No agreed valuation method. Each deal is a handshake on a number that might change tomorrow.
The trend is spreading. What started as a San Francisco curiosity is now a known strategy.
More sellers are asking for equity. More buyers are offering it. The viral text message accelerated everything.
Banafa’s warning is the one nobody wants to hear. Stock falls.
Taxes stay high. The seller who thought they were buying into the future might be buying a tax lien. The buyer who thought they were being clever might have just paid a premium for shares that never list.
For now, the deals close. The houses change hands. The shares change hands.
And the risk sits in the middle, unacknowledged, waiting for the first deal to go wrong.
