Wall Street's IPO machine is suddenly firing on all cylinders again. 

After years of drought, six companies just raised $4.4 billion in a single week: the kind of action we haven't seen since the easy money days of 2021. And now, the startup everyone's watching might be ready to join the party. 

OpenAI, the $500 billion AI powerhouse behind ChatGPT, just struck a deal with Microsoft that could finally unlock its path to going public. CEO Sam Altman admits he's "conflicted" about an IPO, but with $25 billion already flowing into public markets this year, the timing couldn't be more tempting.

Why OpenAI's Microsoft Deal Could Lead to an IPO

Sam Altman has a $500 billion problem that most founders would kill for. OpenAI needs mountains of cash to feed its AI ambitions, but its unique corporate structure makes raising money quite the ordeal. Last week's non-binding agreement with Microsoft might finally untangle the mess and hopes to smooth out the "structural and competitive friction" between the companies. And while both sides stay tight-lipped about the financial details, one thing seems evident: OpenAI's path to a potential IPO may have just got a little clearer.

The Corporate Structure Problem Gets a Solution

OpenAI's setup reads like a corporate law exam question nobody wants to answer. Founded as a nonprofit, the company bolted on a capped-profit arm in 2019 to attract big money from investors like Microsoft. Now they're trying to reshape that profit-focused entity into something Wall Street can stomach: a public benefit corporation (PBC).

The Microsoft deal tackles the structural and competitive friction that's been giving both companies headaches. Converting to a PBC would let OpenAI chase profits while keeping its save-the-world mission intact. The nonprofit parent would still call the shots on operations, but the company could finally raise capital like a normal tech giant and potentially list on public exchanges.

Sam Altman's Very Public Private Company Dilemma

Sam Altman knows everyone wants a piece of OpenAI stock. He admitted to CNBC last month that he feels "very conflicted" about taking the company public. "Whenever we do go public, if we ever go public, I think there will be tremendous upside left in front of the company," he said, before adding the catch: "We're still in a crazy position and it would be very hard for us to be public given just all of the realities of that."

Translation? Running a public AI company while racing toward artificial general intelligence sounds about as easy as teaching a goldfish to code. Yet the Microsoft agreement suggests OpenAI might be warming up to the idea. With IPO fever hitting Wall Street again and investors desperate for the next big tech listing, Altman's conflicted feelings might soon meet an offer too good to refuse.

The Background Context: IPO Market Posts Strongest Weekly Performance Since 2021

OpenAI couldn't have picked a better moment to flirt with going public. Wall Street just threw its biggest IPO party since November 2021, and everyone showed up. Six companies raised more than $100 million each over five days, hauling in a collective $4.4 billion. The Winklevoss twins rang the bell, a Swedish lender convinced Americans to care about buy now, pay later again, and even a coffee chain from the Pacific Northwest got investors caffeinated. 

The $4.4 Billion Week That Changed Everything

Renaissance Capital director Avery Marquez couldn't hide his excitement: "The pickup is here." Six companies breaking the $100 million barrier in one week hasn't happened for nearly four years. Renaissance expects three to five big IPOs per week for the next two months, though they doubt anyone will match this week's fireworks. Bank of America's Jim Cooney put it bluntly: "IPO issuance has exploded post Labor Day." Road shows packed with executives and bankers now rival the chaos of mid-2021's IPO mania. Wall Street's drought officially ended, and everyone wants their turn at the trough.

Meet the New Public Companies 

Friday (September 12) alone saw four companies join the public markets. Gemini Space Station (GEMI), the Winklevoss twins' crypto exchange parent, snagged $425 million and watched its stock jump 18%. Black Rock Coffee Bar (BRCB) proved investors still love their caffeine fix, raising $294 million and rocketing up 45%. Via Transportation (VIA) pulled in $493 million with a modest 3% gain, while building efficiency provider Legence (LGN) grabbed $728 million and climbed 8%. 

Earlier that week, Klarna raised $1.37 billion to become the buy now, pay later giant everyone forgot we needed, though its stock dipped 3%. Figure Technology Solutions scored $787.5 million and rose 7%, turning founder Mike Cagney into a billionaire overnight.

Cagney's Billion-Dollar Battle Cry

Mike Cagney, Figure's co-founder and former SoFi CEO, arguably had the most intriguing quotes and insights of the week after mentioning plans to wield his company's fresh $787.5 million "like a weapon." He told Yahoo Finance the new balance sheet will let Figure "push disruptive blockchain use cases" that would have been impossible without the cash injection. Of course, his newfound billionaire status, courtesy of Figure shares, probably helps his confidence, too. 

Do the Headwinds Even Matter?

Not everyone's popping champagne, though. 

Goldman Sachs CEO David Solomon warned that "risk appetite is definitely out on what I'd say is the more exuberant end of the spectrum." 

Citigroup CFO Mark Mason expects slowing growth through 2026. 

Plus, the Bureau of Labor Statistics admitted the US added nearly a million fewer jobs than initially reported for the year ending March 2025. August's preliminary report showed a pedestrian 22,000 jobs added. 

That said, Renaissance's Marquez noticed something odd: "Uncertainty kind of just seems like something that's on everybody's mind, but not really influencing their risk appetites." 

Investors hear the warnings, shrug, and keep writing checks anyway.

So, Should You Start Refreshing Your Brokerage App?

Here's what we know: OpenAI needs cash, Microsoft wants clarity, and Wall Street just remembered how much it loves IPOs. The $4.4 billion raised last week proves investors will throw money at anything with a ticker symbol, even while Goldman Sachs waves red flags about "exuberant" risk appetites.

Sam Altman's "conflicted" feelings about going public make sense. Running a public company while building AGI isn’t for the faint of heart. But when six companies can raise billions despite job numbers looking concerning and growth forecasts getting slashed, maybe the market's message rings clear: strike while everyone's still drunk on optimism.

Will OpenAI actually pull the trigger? The Microsoft deal suggests yes. The timing screams yes. Altman's hesitation whispers maybe. Place your bets accordingly.
