Today’s Analysis
Behind this series of news stories, there’s actually one core message: traditional financial giants (TradFi) are no longer content with just opening the door for cryptocurrencies—they’re rolling up their sleeves, preparing to take over the entire underlying infrastructure. The NYSE parent company ICE’s $1.6 billion investment in Polymarket is definitely not just a financial investment but a public “surrender.” This signals that the world’s top exchange operators finally acknowledge that, in terms of information aggregation and price discovery, on-chain prediction markets are more efficient than Wall Street’s outdated order books. As prediction markets begin to be absorbed by traditional giants, they cease to be just a geek’s playground and start transforming into the “truth machines” of future financial markets.

Even more interesting are the moves by Mastercard and Morgan Stanley. Mastercard is willing to pay a premium to acquire BVNK, while Morgan Stanley immediately introduces a 0.14% “suicide fee.” The logic behind these moves is consistent: a game of stockpiling. Traditional giants have identified stablecoins and ETFs as lucrative targets, attempting to fill the moat painstakingly built by Web3-native teams through capital acquisitions and price wars.

This means that in the future, we might no longer need to discuss “when will cryptocurrencies become mainstream,” because when you swipe your Mastercard or buy a Morgan Stanley fund, you’re already using the underlying crypto infrastructure—just without realizing it. However, this “reconciliation” process reveals a stark split in regulatory attitudes.

On one hand, U.S. lawmakers plan to exempt stablecoin transactions from capital gains taxes, effectively giving stablecoins a “passport” to become part of everyday payments. On the other hand, the European Central Bank is aggressively pouring cold water on DeFi, even accusing it of “secret centralization.” The logic behind this contrast is simple: as long as you resemble the dollar (stablecoin), you’re a good kid eligible for tax breaks; if you want to decentralize or challenge the banking monopoly on money creation (DeFi), you’re a regulatory target.

The real drama lies in the market pain caused by this “power transfer.” We see miners cashing out wildly, Ark Invest reducing holdings and exiting, which resembles a profit-taking move by old powers and a handover of the battleground to new forces. As Wall Street’s giant ships fully turn towards Web3, the once heroic-style valuation logic is collapsing. This is no longer just about price fluctuations but a final contest over who can define the future decade’s financial clearing rules. For investors, paying attention to candlestick charts is becoming less meaningful; understanding who is buying the underlying protocols’ “voting rights” is far more important.
