OpenAI plans to burn $278 billion by the end of 2030, and this week it couldn't even lock in $20 billion. It spends far more than it earns, so the gap gets paid by the next investor in line. And this week, that line got A LOT shorter. OpenAI went into the week asking for $30 billion at a $1.4 trillion valuation, with a Friday deadline. By Friday it had cut the ask to $20 billion at $1.25 trillion. And the FT says the first close is expected to come in below even that, because some investors cut what they were willing to put in. Now put that next to OpenAI's own numbers: - In the second quarter, OpenAI brought in $6.7 billion and posted a $12.3 billion operating loss, according to the WSJ. That's almost $2 lost for every $1 it earned. - In September, the FT reported a company presentation showing OpenAI expects $278 billion of negative free cash flow from 2026 through 2030. - By my math, that's about $55 billion a year. A $20 billion round covers roughly 4 months of it. The mechanism is simple but terrifying: OpenAI has signed more than $1.4 trillion in compute deals with Oracle, Microsoft, Amazon, and its Stargate partners. Those companies count those deals in their backlogs, and Wall Street prices their stocks on it. But OpenAI can only pay those bills with money investors keep handing it. So the whole AI build-out sits on one assumption: OpenAI can always raise the next round. In June, OpenAI's CFO, Sarah Friar, called an IPO just "another way to fundraise", and said the $122 billion from March was raised to give OpenAI maximum flexibility. She said fundraising would be a key part of building a lasting company. But this week, the fundraising came up a third short. Microsoft's own filing shows how tight this already is. Microsoft booked $10 billion of revenue from OpenAI last quarter, about 11% of its total. In the same 3 months, the bill OpenAI still owes Microsoft grew from $6.0 billion to $7.2 billion. And the timing couldn't be worse. On Friday the Nasdaq had its worst day since June, and it's now 7.8% below its October 6 record. The investors who trimmed their OpenAI checks are watching the AI stocks they already own fall at the same time. The FT also says OpenAI wanted this round closed before Anthropic lists in mid-November, because the two are chasing the same big investors. OpenAI's defenders say it raised $122 billion in March, so it isn't running out of cash next month. Its annualized revenue was about $50 billion at the end of September. And $1.25 trillion is still 47% above the $852 billion it was valued at in March. But a markup that shrinks in a single week tells me the private market just started asking the questions the public market asks every day. Any public company booking OpenAI contracts as future revenue should tell its shareholders how much of that backlog depends on OpenAI raising more money. And OpenAI should publish audited financials before another dollar of retail money flows in, because $3 billion of its March round came from individual investors through bank channels. OpenAI asked for $30 billion this week and investors came back with at least a third less. It's close...
