How Do Sports Prediction Market Startups Raise Money?

Sports prediction market startups raise money from crypto funds, trading firms and exchange operators far more often than from traditional sports investors. Between January and late October 2026, CapSignal logged 11 early-stage rounds in sports prediction markets and the infrastructure behind them. Seven disclosed an amount, adding up to $69.2M. Two of those rounds, ProphetX ($35M) and Onyx Odds ($20M), make up 79% of that total. The other five disclosed rounds were between $1.7M and $3.5M. Most important: the investor list follows the license. How a startup plans to get legal access to US customers decides who will write the check.

Below is what those 11 deals show about stage, round size, lead investors and timing, drawn from the deal log we keep for every issue of CapSignal Sports.

Every early-stage sports deal we track gets a full deal intelligence brief. Filtering those briefs for prediction markets and their supporting infrastructure gives 11 rounds in 2026:

By the numbers. Five seed rounds, one pre-seed, one Series A and four rounds we classify as Other (strategic or unpriced). The median disclosed round is $3.5M. Seven of the 11 have a lead investor named in a company release or trade report.

The timing is the story. Four of the 11 came in the first seven months of the year. The other seven landed between Sept 1 and Oct 15. In Issue #14 we counted four betting and prediction-market infrastructure records in a single month, the highest monthly count in that category since we started logging in January.

One caveat we keep repeating: four of the 11 rounds have no disclosed amount, so $69.2M is a floor for these deals, not a market total.

Look at the cap tables and three groups show up again and again. None of them is a classic sports venture fund.

Crypto-native funds. Coinbase Ventures appears twice, in Pred (through its Base Ecosystem Fund) and in Raven. Maven 11, Blockwall, CMCC Global and 6th Man Ventures all come from crypto. These investors already understand order books, liquidity and on-chain settlement, so a sports outcome market looks to them like another trading venue.

Trading firms and exchange operators. Payward, the parent of Kraken, led Onyx Odds. ProphetX took direct checks from Chicago Trading Company Ventures and Belvedere Trading. FutureSports raised from CME Ventures, Robinhood, DRW and Wedbush. For these investors, a sports contract is a new product to list, clear or make markets in.

Sports and media strategics. FairPlay Sports Media backed WagerWire alongside a distribution deal. FDJ Ventures, the venture arm of France's national lottery operator, joined ProphetX. FutureSports brought in Marquee Ventures, spun out of the Chicago Cubs ownership group, and John and Linda Henry of Fenway Sports Group.

The same names keep returning. Reverie backed both Pred and Furnace. Reciprocal Ventures is in CRSHMARKET and Furnace. That small, repeat group of specialist investors is a useful map for founders building a target list.

A new pool of money is forming too. In March, Bloomberg reported that Polymarket's Shayne Coplan and Kalshi's Tarek Mansour are backing 5c(c) Capital, a venture fund named after the section of the Commodity Exchange Act that covers prediction markets.

In the US, sports event contracts sit under the Commodity Futures Trading Commission (CFTC), the federal regulator for futures and swaps, rather than state gaming regulators. That is still being fought in court. For a founder, it means the first question in any pitch is how you will legally reach customers. Our log shows four answers, and each attracts a different kind of investor.

1. Get your own federal approval. ProphetX began as a sweepstakes platform, then announced CFTC approval to run what it calls the first federally regulated sports-native prediction market. Its $35M round followed. The company says its core metrics rose 50% in the first 30 days of regulated operation, a company claim with no absolute figures attached. Outside our early-stage range, Novig raised a $75M Series B led by Pantera in February on the same plan: leave sweepstakes, apply to become a Designated Contract Market (DCM), the CFTC's term for a licensed exchange. This route needs the biggest checks, because licensing and compliance come before revenue.

2. Rent a license. Onyx Odds runs its markets on Payward's US derivatives business, which holds a CFTC-designated DCM and a registered futures commission merchant (FCM), the broker that holds customer funds. Onyx says this saves it from building its own vendors, licenses and operations. The investor and the license provider are the same company, which explains why the lead was a strategic rather than a VC.

3. Start outside the US. Pred launched excluding the US, India, Singapore and sanctioned regions, which let a $2.5M seed get a product live without a US license. WagerWire's Wire Markets got approval in principle under Gibraltar's prediction-market framework, the second company to do so. Offshore launches mean smaller rounds and crypto-native investors, plus a ceiling on market size until US access is clear.

4. Sell to the exchanges. Six of the 11 deals are infrastructure: Raven makes markets on Kalshi and Polymarket, Oddpool builds prediction-market data and is joining Kalshi, Furnace maps contracts across venues for hedge funds and prop desks, and FutureSports builds performance indexes meant to underpin listed futures. functionSPACE and Open Markets also sit here. Most serve several categories, not only sports. These companies skip the license question entirely, which is why they can raise seed rounds of $3M to $3.5M on a thesis rather than a regulatory milestone.

For founders: Before you build the deck, decide which of the four routes you are on and say it on slide two. The route tells an investor how long it takes to reach revenue, how big the round must be and which risks they are underwriting. A pitch that blurs consumer exchange and infrastructure will reach the wrong investors.

At the early stage, small. Pred's $2.5M seed in Issue #3 was a typical first institutional round: a top-tier lead, a crypto strategic and a product still in private beta. functionSPACE raised $1.7M at pre-seed. CRSHMARKET and Furnace each raised $3.5M at seed.

The jump comes with a regulatory answer. Onyx Odds went from beta to a $220M valuation in under a year, per its release, and we covered that $20M Series A as the moment the category got serious in Issue #10. ProphetX's $35M came after federal approval.

Raven shows the infrastructure path. Its 2024 seed raised $2.7M at a $25M valuation, led by Hack VC. Its September round valued it at $90M before the new money, after it moved from crypto market making into prediction markets.

Mostly, yes. Decrypt reported in March that Kalshi raised $1B at a $22B valuation in a round led by Coatue, double the $11B it set in December. I wrote about what that raise means for the sportsbook model in our Kalshi analysis.

Large venues pull in the startups around them. Raven earns from providing liquidity on Kalshi and Polymarket. Oddpool is joining Kalshi. Furnace sells data about those venues to institutions. The big platforms are now both the reason investors are interested and the likely buyers of the infrastructure companies.

Our October data suggests so. In Issue #15 we logged six betting, fantasy and prediction deals in October, and only one, CRSHMARKET, had a confirmed institutional lead. The rest were smaller consumer apps funded by angels, operators or unnamed backers.

Our read: infrastructure got funded first, and consumer products are now raising cheaper money to build on top of it. That is a good sign for builders and a warning for anyone raising a consumer round. Without a named lead or a license route, these rounds stay small.

What would change our mind: a consumer sports prediction app raising a priced seed above $5M with a named institutional lead and no license of its own. We have not seen one in 2026.
