#Polymarket推私营公司预测市场 Why did Wall Street choose Polymarket instead of building their own?

Yesterday, Nasdaq proactively announced a partnership with Polymarket to launch a private company prediction market.

Some people see this news and their first reaction is "Polymarket is awesome." But my first reaction is: Wall Street folks have finally bowed their heads.

What's interesting about this? It's not that Polymarket found a backer—it's that Nasdaq actively sought out Polymarket. Who approached whom? That’s the clear point.

01
First, let's talk about what happened.

Polymarket is a blockchain-based prediction market. The gameplay is simple: you trade on the outcome of an event, and if you're right, you make money; if you're wrong, you lose money. The platform doesn't tell you the answer—it's in the collective behavior of the participants.
This time, Polymarket partnered with Nasdaq's private market to launch a private company prediction market.
In other words, previously, only institutions and high-net-worth individuals could participate in private company prediction markets—you needed connections, channels, and entry barriers. Now, as long as you can go online, anyone can bet on private companies' performance, mergers and acquisitions, regulatory decisions on Polymarket.
How big is the market? $5 trillion.

Honestly, I can't fully verify this number, but I know one thing: the private company prediction market was once exclusively for institutions. Now retail investors can join, and this market won't be small.

Here's the question: why doesn't Wall Street do it themselves?
Some say Wall Street isn't short of technology, talent, or money. Nasdaq could develop its own prediction market technically—it's entirely feasible. But they haven't.
Why?
Because they can't copy it.
I'm not exaggerating. Over the past twenty years, no fewer than a hundred startups have failed in the prediction market space. It's not that their technology was lacking; the model itself is hard to run: incentive mechanisms are imperfect, user bases are insufficient, regulatory environments are unclear—if any one of these three is missing, the market can't take off.
How does Polymarket solve these issues?
First, token incentives. Participants earn from trading, research yields returns, and the ecosystem spins itself up.

Second, on-chain transparency. All transaction records are publicly accessible, solving trust issues.

Third, regulatory frameworks are gradually becoming clearer. Polymarket has undergone multiple inquiries from U.S. regulators and has addressed all the pitfalls.

Wall Street folks are truly smart and cunning. But if they could copy it easily, they would have done so already. Their proactive approach this time shows that Polymarket's model can't be copied—it's not a technical issue, but a matter of timing and ecosystem. The years of accumulated effort can't be bought with money.

So, Wall Street's choice is simple: since there's already a working platform, why reinvent the wheel?

What does this partnership mean for the industry?
First layer: validation of the business model.

Prediction markets aren't new, but few have succeeded. Polymarket being chosen by Nasdaq is like a traditional financial institution endorsing it with its reputation. In the future, anyone wanting to create a prediction market won't need to start from scratch—they can just copy Polymarket's model or connect to it.
Second layer: Wall Street's attitude toward Web3 has changed.
Previously, traditional institutions' attitude toward Web3 was "study it, then decide." Now, Nasdaq is directly partnering with Polymarket—not just researching, but integrating. What does this mean? It shows that Wall Street is starting to take Web3 seriously, not just paying lip service.

Third layer: real opportunities for retail investors.

This is the most tangible part.

In the past, prediction markets were exclusive to institutions. They held the information advantage, the channel advantage, and the capital advantage. Retail investors were just there to be exploited.
Now, Polymarket allows retail investors to participate. The question is: can retail investors make money?
Yes. But only if you understand the market better than most people.
The essence of prediction markets is information asymmetry. If you have in-depth research on a certain industry or company, your judgment accuracy will be higher than average. This is similar to stock trading in the secondary market—why do you think you can win? Because you understand better than others.

The feedback in prediction markets is faster than in stocks. If you're right, you'll know immediately; if you're wrong, you'll also know right away.

In the future, if mainstream assets like stocks, forex, and commodities also want to develop prediction markets, Polymarket's model can be replicated. Right now, it's just private companies—what about in the future?
"True integration is still early. But this step has indeed been taken."
