Why wasn’t it weird before?

Deeper Undercover
Trump didn’t break the market. He read the manual, found the right box, and put it on a rate card.
There are days I think Trump is deeper undercover than I am.
I don’t mean the routine stuff. Not the swap where the real Air Force One gets traded for a military plane dressed as a catering truck while the marked jet keeps flying as a decoy, everybody else still aboard. That’s not deep cover. That’s seating. And it’s a hell of a way to find out where you rank.
I mean the Truth API.
Since August 1, Trump Media has been selling a low-latency feed of Truth Social posts to trading firms — $60,000 to $100,000 a month, and on the company’s first earnings call this week they said they’d signed more than ten customers, mostly high-frequency shops. What you’re buying is a few milliseconds of head start on a man who announces tariff policy from his phone before his own cabinet hears about it. The company’s defense is that the posts are public and subscribers merely get them fractionally faster.
An anonymous Wall Street executive told NPR that in another administration, this would be considered criminal. Twelve other firms declined to say anything at all, citing fear of retaliation. The silence is the more interesting datapoint.
“That’s weird,” says Matt Levine.
Weird compared to what, Matt?
Here is my problem. This is a man who has patiently explained payment for order flow more times than anyone alive. Selling a few milliseconds of head start to people with the hardware to use it isn’t an innovation. It’s the business. Firms have been buying microwave relays, co-location cages and proprietary feeds for fifteen years to see the market a hair before you do. An entire exchange — IEX — was built around 38 miles of fiber coiled in a box for the sole purpose of making that head start worthless.
So the President priced something the market was already selling. The scandal isn’t that he invented it. It’s the rate card.
Explain it like I’m twelve
Nobody arrests the food taster
Before I get too pleased with myself, I got corrected, so here’s the careful part.
The Secret Service knows where he’s eating tomorrow night. That’s the calendar. Trade on the calendar and you’re a felon. The food taster gets the plate after it’s cooked and before it reaches the mouth. Nobody arrests the taster. The taster has a badge. The taster is the system working.
That’s the whole distinction. Illegal front-running requires a broken promise: someone who owed you a duty looked at your order and stepped in front of it. Latency arbitrage requires no duty at all, because nobody at the trading firm ever promised you anything. They’re just faster to the plate.
| Feature | Illegal front-running | HFT latency arbitrage |
|---|---|---|
| Information source | Private knowledge of a client’s pending order. | Public feeds, read faster than the competition. |
| Duty owed | Breach of duty to a specific client. | No client. No relationship. No duty. |
| Timing | Before the order reaches the market. | After it reaches the market, before it executes. |
| Status | Illegal. SEC and FINRA enforcement. | Legal. Contested, resented, permitted. |
The line is real, and firms do fall off it. FINRA fined Citadel Securities $700,000 in July 2020 for trading ahead of customer orders between 2012 and 2014 — the old-fashioned crime, committed by a modern market maker who had client flow and used it. Athena Capital Research paid $1 million to the SEC in 2014 for jamming orders into the closing auction to push prices where it wanted them. Neither case is about speed. Both are about what you did with a duty you had.
So: is my order material information the moment you have it, regardless of when or where you got it? Sort of, and that’s the uncomfortable part. There’s a fringe theory that you’re supposed to give the market a reasonable interval to digest news before acting on it, which can’t be right, because somebody has to trade first. The honest answer is that the line was never drawn at when you knew. It’s drawn at who you owed.
Fine. But sit with what that means. The legality of the act has almost nothing to do with the act.
The trick, performed three times in three weeks
Put it in a box
Levine has a move he runs on nearly everything: you take some stuff, you put it in a box, the box issues securities, and investors buy claims on whatever the stuff throws off. That’s securitization. It is also, if you tilt your head, the entire American regulatory apparatus. The conduct doesn’t determine the treatment. The box does.
The data centers
On July 29 the SEC’s Division of Corporation Finance told Latham & Watkins that data center securitizations aren’t “asset-backed securities” under the Exchange Act. The reasoning is respectable: a data center isn’t a self-liquidating financial asset, it’s a building full of chips that somebody has to actually run. The consequence is that the 5% risk-retention rule doesn’t apply, nor do the repurchase-demand disclosures, nor the third-party diligence certifications. Skin in the game was the signature post-crisis fix. Issuance in this corner blew past $25 billion last year, more than the prior three years combined, and the sponsors just stopped having to keep any.
The sportsbook
Kalshi lets you bet on football. New York’s attorney general sued on July 31, called it an unlicensed gambling business, and asked for $36 billion. Kalshi’s answer is that these aren’t bets, they’re event contracts on a federally designated market — different box. Then, on Tuesday, the CFTC invoked its statutory emergency powers and ordered Kalshi to keep operating. The emergency is that a court might rule against them. Its chairman warns against subjecting derivatives to a patchwork of state gambling laws, which is a fair point about federalism and also a sentence about sports betting.
The feed
Insider trading means misusing nonpublic information you got through a duty of trust. Trump Media’s box says publisher. A publisher who sells his feed to subscribers isn’t a tipper, he’s a distributor, and what he’s distributing was public the instant he hit post — just less public, for a few milliseconds, to everyone who didn’t pay. Levine’s version is that you aren’t buying the information at all. You’re buying delivery.
Three boxes, three weeks, one trick.
Remedies
The part where nobody can do anything
This is the genuinely funny bit. Congress could tell the President to knock it off; hold your breath at your own risk. The SEC could bring a case; look at the SEC. Investors could sue, except a lot of the subscribers are probably market makers using the feed defensively — pulling their quotes when a war gets announced so they don’t get run over. Which means the people getting picked off in that millisecond are mostly other market makers. The victims here are the guys with the fast feeds. A jury will weep.
Congressman Raskin has opened an investigation. The Intercept and the Freedom of the Press Foundation have sued in New York on the principle that a public official can hold no private property interest in the fruits of his office — which is a real and old idea, deployed here by journalists arguing they’re entitled to the feed at the same moment as the hedge funds. That is a hell of a First Amendment posture and I hope they win anyway.
Where the speed goes
Physicists, and what they do all day
At the far end of that pipe sit some of the best-trained minds in the country, parsing tone and cadence off earnings calls to pull a signal out half a second early. You can call this a tragic misallocation of human capital or you can call it a subsidy for real breakthroughs, and both are true at once.
My favorite version: a few physicists at a financial-data shop in Cambridge built machine learning tools for automating earnings calls, decided they’d rather do something else, quit, and founded Suno — the app that writes you a song from a text prompt. The technology that was going to price your retirement account now makes yacht rock on demand. I’m not being sarcastic. That may be the best outcome in this entire essay.
The pennies
The fund to point at isn’t Renaissance. Medallion makes its money on statistical signals over minutes and days; it isn’t sitting on the wire eating your order. The one you want is Virtu. When they filed to go public in 2014, they disclosed that across 1,238 trading days they had exactly one losing day.
One.
That is not a trading strategy. That’s a toll booth with a very good lawyer.
They made billions out of pennies, a microsecond at a time, and every last penny of it was legal, because pennies come in the right box. Nobody goes to jail over a penny. That isn’t a loophole in the design. That is the design.
Trump found the box, priced it at a hundred grand a month, and put it on the website.
Which is the least undercover thing anybody has ever done. And now that I’ve typed it out, I notice that’s exactly how the best cover works.
