On September 8, 2026, three announcements landed at the same time and most people read them as one story. They are three different stories, and understanding each separately is the only way to understand what is actually happening in the prediction markets space.
First: Citadel Securities invested in Crypto.com at a $20 billion valuation. Second: as part of that transaction, Crypto.com's prediction markets business was spun off as an independent company — OG.com — at a standalone valuation of $5 billion. Third: Robinhood designated OG.com as the infrastructure and clearing provider for its prediction markets offering, and took equity stakes in both Crypto.com and OG.com as part of the deal.
Three separate capital events. One coordinated strategic realignment. And a clear signal about where the money believes this market is going.
What OG.com Actually Is
OG.com is not a new company. It is the prediction markets infrastructure that was built inside Crypto.com and is now operating as a standalone entity. The core asset is the North American Derivatives Exchange — Nadex — a CFTC-regulated designated contract market and derivatives clearing organisation. This is not a crypto exchange operating in a grey area. It is a federally regulated derivatives exchange, operating under the same regulatory framework as futures markets, registered with the Commodity Futures Trading Commission.
The CFTC regulation is the key to everything that follows. The two dominant players in prediction markets — Kalshi and Polymarket — have fought different versions of the same battle. Kalshi's path to CFTC approval involved years of litigation and a court victory that reshaped the regulatory landscape. Polymarket operates with offshore registration and has faced US regulatory scrutiny. OG.com inherited a CFTC-regulated exchange infrastructure that was already built.
That infrastructure is what Robinhood is buying access to. Not the brand. Not the product. The regulated clearing house.
Why Robinhood Didn't Build Its Own
Robinhood has 24 million funded accounts. It launched prediction markets for US customers and the demand was immediate — prediction markets are the product category that converts casual retail interest into active trading in a way that traditional brokerage products do not.
The problem is infrastructure. To operate a prediction markets exchange at scale in the US, you need CFTC registration, a clearing house, and the operational infrastructure to handle high-frequency event contract trading. Building that from scratch takes years and costs hundreds of millions of dollars. Kalshi spent roughly five years and significant legal fees just getting regulatory approval. Robinhood's retail distribution advantage is wasted if the clearing infrastructure behind it cannot handle volume.
OG.com solves that problem immediately. Robinhood routes retail event contract volume through OG.com's exchange and clearing architecture. OG.com handles the regulatory compliance, the clearing, and the institutional-grade liquidity infrastructure. Robinhood provides the 24 million customers. The equity stake aligns the incentives: Robinhood now has a direct financial interest in OG.com scaling successfully.
This is why companies take the partnership route rather than building independently. The build path is slow and expensive. The partnership path trades economics for speed. When the market is moving as fast as prediction markets are moving in 2026, speed wins.
Kalshi, Polymarket, and the 95% Problem
The honest reality of the prediction markets space is that two companies hold the overwhelming majority of volume. Kalshi and Polymarket together account for well above 90% of US prediction markets trading by most estimates. The 40+ other companies operating in the space — exchanges, platforms, aggregators, protocol layers — are competing for the remainder.
The strategic question for every new entrant is the same: how do you break into a market with that level of concentration? The Robinhood-OG.com answer is distribution. If you cannot out-trade Kalshi, partner with the largest retail broker in the US and become the infrastructure layer behind 24 million retail accounts. OG.com does not need to acquire Kalshi's customers directly — it needs to be the clearing house that Robinhood's customers interact with every time they place an event contract.
The Citadel stake adds another dimension. Citadel Securities is the largest US retail market maker by volume. Its participation in prediction markets infrastructure signals that institutional liquidity providers are treating this asset class as permanent — not experimental. When Citadel takes a stake, it is not making a bet on Crypto.com's token. It is making a bet on the regulated derivatives infrastructure for event contracts.
What This Means for the Market
The prediction markets space in 2026 is in the phase that every financial market goes through before it matures: a land grab for regulatory positioning, distribution, and institutional backing. The companies that win that phase do not necessarily win because they have the best product. They win because they have the clearing infrastructure, the regulatory standing, and the distribution relationships that make them the path of least resistance for the next wave of capital.
OG.com's $5 billion spin-off valuation is a bet that CFTC-regulated prediction market infrastructure, at scale, is worth at least that as a standalone business — separate from Crypto.com's digital asset exchange, separate from the brand, as pure clearing infrastructure. The Robinhood partnership gives that infrastructure immediate scale. The Citadel stake gives it institutional credibility.

The Infrastructure Play
The pattern here is not new. Every time a new financial product category scales from early adopters to mainstream retail, the infrastructure layer becomes the most valuable part of the stack. Visa and Mastercard are more valuable than most of the banks that issue cards on their networks. DTCC is more valuable than most of the brokers that clear through it. The exchange and clearing infrastructure captures value at every transaction, regardless of which platform the customer uses.
OG.com is positioning for that role in prediction markets. If Robinhood routes volume through OG.com's clearing house, and other retail platforms follow the same path because OG.com has the regulatory infrastructure they need, OG.com becomes the DTCC of event contracts. The $5 billion valuation implies investors believe that outcome is plausible. The Citadel and Robinhood combination suggests the smart money agrees.
Whether OG.com can actually execute that vision against Kalshi's regulatory head start and Polymarket's brand recognition is the open question. What is not open is the direction the market is moving. Prediction markets are becoming a permanent category of US regulated derivatives trading. The infrastructure build-out is accelerating. The institutional capital is arriving.
The only question left is which clearing house the industry converges on.
