Robinhood spent Tuesday on a stage in London, and by the end of it the app most people use to buy shares had turned into a blockchain.

The event was called The World is Flat. On it, Vlad Tenev's company switched on Robinhood Chain. It's their own network, built on Ethereum using the same tech as Arbitrum. In plain words, Robinhood now runs its own patch of the crypto world, and it has started moving its business onto it.

Here is what that means day to day. Outside the US, you can now buy and sell tokenised versions of real shares around the clock. Apple at two in the morning, if you like. Inside the Robinhood Wallet you can now make perpetual bets — leveraged wagers on which way a price moves, the kind that never used to sit inside a mainstream app — powered by Lighter, a fast trading engine built on Ethereum. In America, where the rules are tighter, Robinhood turned on lending against a dollar stablecoin instead. For ninety days it is charging nothing to use any of it.

Why the timing matters. The crypto funds have just had their worst six months ever. Money left the Bitcoin and Ethereum ETFs for the first half-year on record. Read only the fund flows and you would think Wall Street had given up. It hasn't. It is doing something heavier. Renting exposure through a fund is the easy way in. Building your own chain, and putting your customers' trades on it, is the committed way. One you can sell in a click. The other you have to mean.

For anyone holding crypto, that is the thing worth seeing under an ugly tape. The price is down and the plumbing is being laid anyway — by the company that taught a generation to tap Buy.

Raoul Pal sat down this week with Tarek Mansour, the man who built Kalshi, and the pitch was simple. The betting markets everyone once waved off as gambling are turning into something Wall Street now needs.

Kalshi and Polymarket let you put money on real questions — who wins an election, where inflation lands, whether a company goes public. When enough people bet real cash, the odds become a live price on things markets used to just guess at. Mansour's argument is that to value the S&P or the jobs market now, you need a read on AI and politics, and these markets price exactly that.

The numbers back the talk. The two venues cleared around $45 billion in bets in June alone, up three-quarters in a single month. The corner nobody took seriously is becoming plumbing.

The US government released Donald Trump's yearly financial disclosure on Tuesday, all nine hundred pages of it, and one number jumped out. His family's crypto ventures brought in around $1.4 billion last year.

The same filing landed on a bad week for everyone else. Roughly two in three of the people who bought his own memecoin, the $TRUMP token, are sitting on losses. So the President made a fortune on crypto while many of the fans who bought in on his name are underwater.

That gap is the thing to keep an eye on. Every pro-crypto move this White House makes now carries a question about who it really pays. And the disclosure lands right as Congress fights over the big crypto rules, the ones that decide what this whole market is allowed to become.
