So everyone's talking about potential SpaceX IPO and OpenAI going public eventually, but here's what's actually happening in tech capital markets right now — it's all about debt, not equity.

The big four hyperscalers — Alphabet, Amazon, Meta, Microsoft — are looking to dump close to $700 billion this year alone on AI infrastructure and capex. That's a staggering amount, and they're not just pulling from their cash reserves. They're aggressively tapping the debt markets to fund this AI arms race.

I've been watching the numbers and they're pretty wild. UBS just came out with a report showing that tech and AI debt issuance globally hit $710 billion last year and could reach $990 billion in 2026. Morgan Stanley's even more bullish — they're projecting a $1.5 trillion financing gap for the whole AI buildout that'll likely be filled by corporate debt.

What's interesting is how this is playing out in real time. Oracle started the wave in early February, announcing plans to raise $45-50 billion for AI capacity and quickly dropped $25 billion in debt. Then Alphabet came through this week with a $30+ billion bond offering, after already doing a $25 billion sale back in November. Amazon's filing mixed shelf registrations. Meta's CFO is openly talking about taking on debt. Even Tesla's signaling they might tap external financing.

Meanwhile, the IPO news today keeps hyping SpaceX potentially going public mid-2026 after Elon merged it with xAI at a claimed $1.25 trillion valuation. OpenAI and Anthropic are supposedly eyeing public debuts too, but there's no real timeline. Goldman Sachs expects around 120 IPOs this year raising $160 billion, which sounds decent on paper.

But here's the thing — that IPO activity is getting completely overshadowed by what's happening in the debt markets. The tech sector is basically saying we need capital NOW for AI, and the debt market is the fastest way to get it.

What worries me though is the concentration. Tech is already about 9% of investment-grade corporate debt indexes, and analysts think it could hit the mid-to-high teens soon. When you've got that much supply from a handful of mega-cap companies hitting the market, it starts to distort pricing. Alphabet's sale was five times oversubscribed, but that kind of volume eventually pressures yields and makes it more expensive for everyone else.

The real risk isn't necessarily the big tech companies — they're profitable and can service debt. It's what happens to mid-tier companies when rates stay elevated and they need to refinance. Higher debt servicing costs across the board could become a serious problem.

So yeah, while everyone's waiting for the next big IPO news in tech, the actual story is this massive debt issuance wave that's reshaping how these companies fund their AI infrastructure. That's where the real capital markets action is right now.
