1789 Capital's Polymarket stake draws a second political investor

Polymarket's billion-dollar funding round closed with a name that was already covered — 1789 Capital, the conservative venture fund anchored by Donald Trump Jr., whose involvement Representative Jamie Raskin flagged in an inquiry filed the same week. That story is on the record. What the reporting has not fully worked through is what the investor composition means for how regulators will read the platform's next move.

Tony Lee, Alpaca's Chief Brokerage Officer, gave a cleaner answer about the international expansion logic than most executives do when asked why they entered a new category. He said it plainly: the customers asked for it. Alpaca had 14 million brokerage accounts and 300 institutional partnerships before it registered as a futures commission merchant with the CFTC. The Kalshi arrangement gives those accounts access to event contracts through infrastructure they already use. That is not a product launch — it is a distribution unlock, and the distinction matters for how quickly volume can move.

Max Crowley at Kalshi described the Alpaca relationship as a technical foundation for international scaling. The Canada partnership with Wealthsimple was the first public step. Alpaca is the second. The pattern is CFTC-licensed infrastructure partners in markets where event contracts sit in a legal grey zone — which is to say, most of them.

Here is where I would push back on the prevailing read. The consensus frames Kalshi's international expansion as a regulatory arbitrage play: build volume abroad while the domestic legal situation resolves. I think that framing inverts the actual mechanism. The international partnerships are not a hedge against domestic risk. They are the argument Kalshi makes to the CFTC and to the courts — that event contracts are a global asset class with institutional distribution, not a domestic gambling product with a technology layer on top. Yoshi Yokokawa, Alpaca's CEO, used the phrase "asset class" explicitly. That language is not accidental. It is a jurisdictional claim dressed as a market observation.

The August volume drop across the two largest platforms is the number worth sitting with. A 14.5% month-over-month decline during a period when Polymarket closed a round at a valuation that would make most Series B founders reconsider their career choices is a structural signal, not a seasonal one. Volume and valuation moving in opposite directions means the capital is pricing the option, not the current flow. That is a reasonable bet if you believe regulatory resolution expands the addressable market by an order of magnitude. It is a dangerous one if resolution comes in the form of a Supreme Court ruling that goes the wrong way on the CFTC authority question.

The Ninth Circuit's characterisation of Kalshi's contracts as gambling and the Nevada court's contempt threat are both on the record. What is not yet on the record is whether the CFTC, under its current leadership, will file a position that distinguishes financial event contracts from sports wagering before the Supreme Court takes the question. Whether the Commission has taken an internal position on that distinction is not public. That is the variable the Alpaca partnership is designed to pre-empt — by making the international institutional infrastructure real enough that any regulatory ruling has to reckon with what it would unwind.
