Meta Building a Prediction Markets App: Why Dean Sisun Says Buy an Exchange Instead
Meta is reportedly building its own prediction markets platform. The news broke this week and immediately sparked debate about how a company with three billion users could reshape the space.
Dean Sisun, co-founder and CEO of ProphetX, sees acquisition as the faster route. He points to Robinhood’s recent moves as a model worth replicating at scale. From an operator perspective this raises immediate questions about distribution power versus the mechanics of building liquidity and regulatory infrastructure.
The Robinhood Playbook Meta Should Study
Robinhood used to send all its prediction market traffic to Kalshi. Last November it acquired MIAXdx, a designated contract market and derivatives clearing organization. It partnered with market maker Susquehanna and relaunched the exchange as Rothera earlier this month.
Sisun likes what he sees. He told Gambling Insider that the joint venture includes the three essential pieces of a prediction market: a platform, liquidity, and distribution.
“You get every facet of the pie. You have the exchange, you have the market maker, and then you have the distribution flow, and then it’s just a game of how you split it up between the three of you.”
“I think what Robinhood did is so interesting, the JV model they put together.”
“I think that is the model that a big company like Meta should be following.”
After eighteen years across iGaming and sportsbook operations the pattern is familiar. Distribution alone does not win. You still need someone who can price risk and someone who can clear it. Meta owns the eyeballs. The missing pieces are not trivial.
Building from Scratch Versus Buying Speed
Meta’s initial plans for the app, internally called Arena, involve trading video-game-like points. The New York Times report notes the company has not ruled out using real money at some point.
Sisun does not believe transitioning from points to dollars would be too difficult for a company like Meta.
“If they launched either a product or a wallet within some of their products, they could get a lot of funds on site very quickly.”
He argues that if Meta is serious about competing and wants to get up and running quickly it should buy rather than build. The company already owns Instagram, WhatsApp and Messenger. That gives it unmatched distribution.
“If you’re sitting on the king of distribution, I think the other two are probably assets you wanna buy just to move as quickly as possible. If you wanna build them yourself, it’s gonna take probably years to do that. So if I’m them, I’m probably buying someone in the space.”
ProphetX itself received approval as a designated contract market and derivatives clearing organization from the CFTC about two weeks ago. The timeline matters. Regulatory readiness is not instantaneous even for well-resourced teams.
Distribution Edge Meets Liquidity Reality
Robinhood’s 28ish million users are a fraction of Facebook’s three or so billion. The potential scale is obvious. Funneling even a small slice of that audience into prediction markets could dwarf current volumes.
Yet the sports betting and prediction market businesses have shown that user access is only one variable. Kalshi, FanDuel and DraftKings all benefit from massive user bases. The real test is converting casual browsers into active participants who understand contract mechanics and accept the risk.
From the supplier side this kind of regulatory and operational layering is what stalls commercial deals. Meta can push funds on platform fast. Clearing, market making and compliance take longer. Buying those capabilities compresses the timeline.
Sisun clarified that he did not plant the tweet from Sam Schwartz suggesting Meta acquire ProphetX or Novig. The tweet appeared a day before they spoke. Still he seems to like the idea.
Risks and Counterarguments to the Acquisition Thesis
Not every tech giant has succeeded when it stepped into gambling-adjacent spaces. The 2017 ESPN report by David Purdum and Ryan Rodenberg predicted that some of the world’s largest tech companies would emerge as bookmaking giants after the repeal of PASPA. That forecast has not fully materialized.
Sisun recalls Microsoft applying for a patent for a sports betting exchange as he was standing up his company in 2018.
“I always thought maybe they would try to do something.”
The counterargument is straightforward. Regulatory scrutiny on real-money prediction markets is intense. Even with deep pockets Meta would face CFTC oversight, potential state-level friction and questions around social platforms and gambling. Building compliance from zero is expensive. Buying it still requires integration work that can slip timelines.
Liquidity does not appear overnight. A market maker partnership helps but sustained two-way flow depends on user behavior that no acquisition automatically delivers. The Robinhood model succeeded because it layered onto an existing trading audience. Meta’s users skew more casual. Converting them at scale is unproven.
There is also the question of focus. Meta’s core business is social connection and advertising. Prediction markets introduce new reputational and legal risks. The upside is clear on paper. Execution risk remains material.
What Other Tech Giants Might Do Next
The Meta news immediately raises the next logical question. If a company with three billion users is moving in this direction who follows?
Sisun wonders aloud about Amazon. He asks whether any move would be sports focused, news focused or crypto focused.
“It makes you wonder, if Meta is doing this, who’s next?”
The pattern from sports betting legalization suggests big tech has flirted with these markets for years without fully committing. A successful Meta entry could change the calculus. It could also highlight how difficult it is to translate social scale into trading liquidity.
The Bottom Line
Sisun makes a pragmatic case. Meta holds unmatched distribution and could accelerate entry by acquiring a regulated exchange and partnering for liquidity rather than spending years building both. For industry executives the signal is clear: scale alone does not solve infrastructure gaps. The operators and platforms that have spent the last decade sharpening risk, clearing and compliance now sit as attractive acquisition targets. Watch who moves first and how cleanly the integration lands. That will tell us whether big tech truly rewrites the prediction market playbook or simply rents the existing one.
