Behind the Boom of Prediction Markets: How Does Polymarket Use Blockchain to Reshape Betting Platforms?

Data Speaks

In 2024, there’s a platform growing at a speed rivaling crypto legends. Polymarket surged from $110 million in monthly trading volume and 30,000 active users in June to $27.6 billion in monthly trading volume and 450,000+ active traders in October. What does that mean? A 250x increase.

What’s driving this? The US election. The platform’s biggest single bet—“2024 US Election Winner”—has accumulated $2.6 billion in wagers. According to the data, the market currently gives Trump a 66% chance of winning, and Harris 34%. Every second, people are putting real money behind their political predictions here.

Why Choose a Decentralized Betting Market?

Traditional prediction sites like PredictIt are regulated in the US, with lots of hassles: betting limits, KYC checks, regional restrictions. Polymarket bypasses all of these.

Key differences:

• No KYC login: You can play with just a wallet address
• Low trading fees: Uses Polygon Layer-2 instead of Ethereum directly, minimizing fees
• Non-custodial model: Your private key stays with you, the platform never touches your funds
• Available globally (except in the US)

This is the promise of Web3—cutting out middlemen and letting strangers bet directly against each other.

How to Play?

1. Connect your MetaMask wallet and deposit USDC stablecoin
2. Choose an event market (politics, sports, crypto prices, etc.)
3. Buy “Yes” or “No” shares, priced between $0.01–$1 each
4. If your prediction is correct, each share is worth $1; if not, they’re worthless

For example, will BTC break $70,000 in October? This market already has $2.1 billion in bets. As the odds change, prices update instantly.

Assessing the Potential Through Fundraising

What convinced Silicon Valley heavyweights to back founder Shayne Coplan?

• Series A: $25 million led by General Catalyst, with Airbnb co-founder Joe Gebbia participating
• Series B: $45 million led by Thiel’s Founders Fund, with Ethereum co-founder Vitalik Buterin, Dragonfly Capital, and others joining

What does this mean? Big institutions believe this sector has real potential.

What Are the Risks?

Don’t be blinded by the numbers—Polymarket has its weaknesses:

1. Regulatory pressure: CFTC previously fined them $1.4 million; banned in the US
2. Market manipulation: A whale’s big order can instantly shift probabilities, causing volatility
3. Technical glitches: On-chain smart contracts can have bugs, potentially freezing your funds
4. Outcome verification challenges: Relies on oracles and an arbitration committee, which can be subjective
5. Information pollution: Fake news can alter market pricing

What’s Next?

Everyone in the space is waiting for one thing—Will Polymarket launch a token?

Rumor has it that $50 million in funding is earmarked to kickstart a token economy, with potential airdrops for early users. If that happens, the logic comes full circle: governance tokens for user participation, rewards to maintain momentum, ecosystem lock-in.

But until there’s an official announcement, it’s all speculation. Investing in prediction markets is inherently risky, and chasing the hype is even riskier.

Key Takeaway: Polymarket isn’t just a money-making casino—it’s commercializing market prediction. Behind every real price signal is the aggregation of information from thousands of people. This is more accurate than traditional polling, because wallets don’t lie.
