Today’s Analysis
Behind this series of news today lies just one core message: traditional financial giants (TradFi) are no longer content with merely opening the door for cryptocurrencies—they are 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that, in terms of information aggregation and price discovery, on-chain prediction markets outperform Wall Street’s outdated order books. When prediction markets start being absorbed by traditional giants, they cease to be just a geeky game and begin transforming into the “truth machine” 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 and are 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 are already using the underlying crypto infrastructure—just without realizing it. However, in this “reconciliation” process, regulators’ attitudes show a stark split.
On one hand, U.S. lawmakers plan to exempt stablecoin transactions from capital gains tax, 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 are a good kid and can enjoy tax cuts; if you want to decentralize or challenge the banking minting rights (DeFi), you become a regulatory target.

The real focus is on 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 forces and a handover of positions to new ones. As Wall Street’s giant wheel fully turns toward Web3, the original hero-like valuation logic is collapsing. This is no longer just about price fluctuations but a final battle over who can define the future decade’s financial clearing rules. For investors, watching candlestick charts is becoming less meaningful; understanding who is buying these underlying protocols’ “voting rights” is far more important.
