The IPO market roared back to life in 2025 with some massive debuts—and a few stocks absolutely skyrocketed after going public. Medline just pulled off the year's biggest offering, but wait until you see which company delivered nearly 170% gains in just months...

Remember those gloomy predictions a couple of years back that the IPO market might never recover? Well, 2025 has quietly proven everyone wrong. I’ve been watching these markets for years, and there’s something genuinely exciting about seeing companies finally step into the public spotlight again after a long drought. This year felt like the dam finally broke, with new listings popping up left and right—and some of them delivering returns that make even seasoned investors do a double-take.

It’s not just the sheer number of deals that caught my attention. What really stands out is how certain fresh public companies have performed since their debut. A few have more than doubled in value in months, while others have settled into solid gains. In my view, that’s the real story of 2025: not just that the window reopened, but that investors rewarded some of these newcomers handsomely.

A Remarkable Comeback for New Stock Listings

The numbers tell a compelling tale on their own. Through the first nine months of the year, over 175 companies made their public debut on U.S. exchanges. That’s the strongest pace we’ve seen since the frenzy of 2021. Sure, we’re not quite back to those wild heights yet, but the momentum feels real. Perhaps the most interesting aspect is how selective investors have become—they’re not chasing every deal, only the ones with clear growth potential.

One massive offering just closed out the year on a high note: a medical supplies giant that raised more than $6 billion in what became the largest debut of 2025. Shares started trading around mid-morning and quickly found their footing. It’s the kind of landmark transaction that signals confidence is truly returning to the market.

But size isn’t everything. Some smaller—or at least mid-sized—deals have delivered the kind of fireworks that get traders talking. Let’s dig into the standouts that really moved the needle this year.

The Medical Giant’s Monumental Debut

When a company in the healthcare supply space decides to go public with a multi-billion-dollar offering, people notice. This particular firm sold hundreds of millions of shares and brought in roughly $6.26 billion. Trading began on a major exchange with shares opening solidly in the mid-thirties.

Why does this matter beyond the headline figure? Because healthcare remains one of those defensive sectors that investors flock to during uncertain times. Yet this debut happened amid broader market strength, suggesting institutions are comfortable taking on new names again. I’ve found that when established private companies finally list, it often marks an inflection point for the entire IPO ecosystem.

The timing couldn’t have been better either. Coming right at year’s end, it caps off twelve months of steadily improving conditions for new issuances. If you’re wondering whether the revival is sustainable, deals like this provide pretty convincing evidence.

Crypto’s Blockbuster Return to Public Markets

Few sectors generate as much buzz as cryptocurrency, and one stablecoin issuer delivered arguably the most electrifying performance of the year. Back in June, the company raised just over a billion dollars and saw its shares blast off from day one.

Picture this: the initial pricing came in at $31, but when trading started, shares opened nearly 120% higher. That’s the kind of pop that reminds everyone why IPOs can be so addictive. Since then, the stock has climbed another serious leg higher—up around 168% from that debut price.

Now sporting a market value closing in on $20 billion, it’s become one of the heavyweight names in digital assets trading under public scrutiny. In my experience, when a crypto-related company achieves this kind of trajectory post-listing, it tends to bring fresh attention to the entire space. Investors who missed the boat early must be kicking themselves.

The successful public debut of major players in digital finance shows that institutional comfort with the asset class has grown dramatically.

Whether you’re a believer in stablecoins or not, you can’t ignore returns like these. They highlight how quickly sentiment can shift when fundamentals align with market appetite.

A Mining Company That Quietly Crushed It

Sometimes the biggest surprises come from less hyped sectors. Take this Canadian miner that went public over the summer with a roughly $200 million raise. Shares were priced in the mid-twenties, nothing earth-shattering at first glance.

Fast forward a few months, and the stock has almost doubled—up close to 92%. With a market cap pushing $4 billion now, it’s turned into one of those steady climbers that reward patient holders.

Commodity plays can be volatile, no question. But when underlying demand for metals stays firm and operational execution looks solid, these names have real staying power. I’ve noticed that resource companies often fly under the radar during IPO season, only to emerge as top performers later.

  • Modest initial raise kept expectations reasonable
  • Strong operational updates post-listing drove momentum
  • Nearly doubled market value in under six months

If there’s a lesson here, it’s that glamour isn’t everything. Solid businesses in traditional industries can deliver outstanding results when conditions align.

Options Trading Platform Joins the Party

Another intriguing debut came from a financial marketplace focused heavily on options trading. The August listing brought in about $345 million, with shares priced above the expected range—a sign of strong demand right out of the gate.

Opening day saw shares jump nicely, and the gains have kept coming. Up around 88% since trading began, the holding company now carries a valuation near $3.5 billion.

What’s fascinating to me is how this reflects growing retail and institutional interest in derivatives. Options volumes have been setting records, and having more specialized venues go public feels like a natural evolution. When a platform captures that wave successfully, the payoff can be substantial.

These kinds of infrastructure plays often become overlooked gems. They’re not as sexy as the next tech unicorn, but they provide essential services that traders rely on daily.

What Made These Deals Stand Out

Looking across the top performers, a few common threads emerge. First, pricing discipline mattered immensely. Several of these companies came to market at valuations that left room for upside, rather than pushing aggressive multiples.

Second, sector tailwinds played a huge role. Healthcare resilience, crypto adoption, commodity demand, and derivatives growth—all provided fertile ground for new listings to flourish.

Finally, operational delivery post-IPO has separated winners from the pack. Companies that hit guidance, expanded margins, or captured market share quickly saw their stocks rewarded.

Company SectorRaise AmountPost-IPO GainCurrent Market Cap
Medical Supplies~$6.3BNew listingMulti-billion
Stablecoin Issuer~$1B~168%~$19.5B
Mining~$196M~92%~$3.9B
Options Platform~$345M~88%~$3.5B

Numbers like these don’t happen by accident. They reflect genuine investor enthusiasm meeting solid business execution.

Why the IPO Revival Feels Different This Time

We’ve seen hot IPO periods before, only to watch many names fade quickly. So what makes 2025 feel more sustainable? For one thing, companies appear better prepared. Many spent extra time as private entities building scale and profitability.

Interest rate expectations have also helped. With central banks signaling easier policy ahead, growth stories become easier to fund in public markets. Add in healthy corporate balance sheets and plenty of dry powder on the sidelines, and the ingredients for continued activity look promising.

That said, not every debut has been a home run. Selectivity remains key—investors are quick to punish overreach. But when the setup is right, as we’ve seen with these top performers, the rewards can be substantial.


Stepping back, 2025 will likely be remembered as the year the IPO market genuinely turned the corner. From multi-billion healthcare giants to crypto trailblazers and steady commodity players, the range of success stories shows breadth in the recovery.

In my view, the most encouraging sign isn’t any single massive deal—it’s the consistent outperformance across different industries. That suggests structural improvement rather than temporary hype.

As we head into 2026, the pipeline reportedly remains healthy. If economic conditions cooperate, next year could build on this foundation. For anyone who’s been waiting on the sidelines, watching these 2025 winners might just provide the nudge needed to pay closer attention.

After all, catching the next big mover early is what makes following markets so compelling. And based on this year’s evidence, there are clearly still plenty of opportunities emerging.
