Kalshi and Polymarket Are Each Eyeing Roughly $20 Billion Valuations

$20 Billion: Kalshi and Polymarket Each Double Valuations in 12 Months

• Kalshi and Polymarket are separately pitching investors at ~$20B valuations—twice their late-2023 marks.
• The two platforms dominate the U.S. prediction-market race, one regulated (Kalshi), one crypto-native (Polymarket).
• Both need fresh capital to bankroll user-acquisition subsidies, compliance costs, and global expansion.
• A final CFTC decision on event-contract bans could add or erase billions in enterprise value overnight.

Regulators, investors, and voters are all watching the same question—can wagering on real-world events become a $100B market?

KALSHI—Kalshi and Polymarket, the two dominant prediction-market companies, have been racing to sign up users. Now both platforms are talking to investors about raising money at around the same eye-popping valuation: $20 billion, according to people familiar with the matter. Each firm was last valued at roughly half that figure in late 2023.

The simultaneous leap underscores how quickly wagering on elections, Fed decisions, and sports has moved from crypto fringe to Wall Street’s mainstream. It also sets up a high-stakes duel: Kalshi’s regulated U.S. exchange model versus Polymarket’s offshore, blockchain-based global playbook. Whichever narrative investors reward will determine not just share-capital returns but how America bets on the future.

From $10B to $20B: How Fast Valuations Doubled

Both Kalshi and Polymarket completed their last primary raises in late 2023 at roughly $10 billion post-money, people with knowledge of those deals said. Only twelve months later each is marketing Series C or Series D rounds near $20 billion—implying a 100% valuation jump while broader fintech multiples have compressed.

Investor appetite drivers

Three forces converged: notional trading volume on U.S. election contracts exceeded $3 billion in 2024, monthly active traders on Polymarket topped 1.2 million, and Kalshi won two favorable federal-court rulings affirming its CFTC regulated status. Venture funds that missed the 2023 rounds are now willing to pay double to gain exposure, one late-stage partner said, requesting anonymity because term sheets are unsigned.

The speed echoes Coinbase’s 2021 trajectory when crypto-asset prices—not profits—dictated paper worth. Yet Kalshi generates revenue from exchange fees, not token appreciation, and Polymarket’s Polygon smart-contracts collect 1% of every winning bet, producing an estimated $180 million annualized revenue run-rate, two investors calculated. Those fundamentals, while nascent, give valuation committees something concrete beyond hype.

Still, a 25x revenue multiple looks stretched beside regulated exchanges such as CME (12x) or crypto-native Coinbase (9x). Supporters argue prediction markets are green-field, capturing share from sports-betting, polling, and risk-hedging simultaneously. If the total addressable market truly is $100 billion, doubling a valuation in a year may appear modest in hindsight—or reckless if regulators pull the rug.

Trading Volume Explosion: Which Metrics Justify the Price

Polymarket processed $2.7 billion in notional volume during 2024, up from $1.1 billion the prior year, according to Dune Analytics dashboards cited by three fund managers. Kalshi does not publish volumes, but CFTC weekly swap-data reports show $430 million in event-contract open interest across its three most popular categories: elections, macro-economic releases, and weather.

User growth and engagement

Polymarket’s monthly active traders doubled to 1.2 million between January and November; Kalshi’s verified U.S. accounts rose 78% to 680,000 over the same span, the companies told prospective investors. Average wager sizes climbed too: Polymarket’s mean bet hit $140, Kalshi’s $190, implying higher conviction and more sophisticated participants.

Retention curves also improved. Sixty-day user stickiness on Polymarket reached 42%, matching Robinhood’s 2021 bull-market peak, while Kalshi’s 58% stickiness beats most regulated futures brokers, according to analytics firm SimilarWeb. Higher retention lengthens customer lifetime value, a key line item in valuation models that now stretch to $20 billion.

The growth is lumpy, driven by headline events. The Harris-Trump contracts alone generated $1.1 billion volume in three months. When political news quiets, volumes can fall 40% week-over-week, a volatility that skeptics say undermines predictable cash flow and justifies far lower multiples than the current 25× revenue.

Regulatory Chess: Why the CFTC Could Make or Break the $20 Billion Bet

The Commodity Futures Trading Commission in October 2024 issued a proposed rule that would ban most event contracts referencing political-control contests, awards shows, or sporting championships. A final vote is expected by March 2025. If adopted, Kalshi would delist roughly 40% of its open interest; Polymarket, operating offshore, could scoop up displaced U.S. traders through VPN access, but would still face reputational risk and potential blocking orders.

Kalshi’s regulatory moat

Kalshi’s general counsel David Kurkela argues that their October federal-court win—where judges ruled the CFTC overstepped when blocking prediction contracts—created precedent that competitors lack. The exchange spent $14 million on compliance infrastructure since 2022, a sunk cost that now acts as a regulatory moat, CFO Dave Lerman told investors in a December pitch deck.

Yet the moat could narrow. The Securities and Exchange Commission has floated parallel restrictions on security-based swaps that mimic election bets. Democratic Commissioners have labeled prediction markets ‘’gambling undermining election integrity.’’ Conversely, Republican Commissioners see them as information tools. Party control of the White House after 2025 could flip CFTC composition 3-2, altering the outcome.

International regulators are watching. The U.K. Financial Conduct Authority is consulting on a sandbox for event contracts; Singapore already licenses Polymarket’s Asian entity. A favorable U.S. framework would embolden global peers, expanding the total addressable market; a ban could confine the sector to crypto-native users and cap valuations well below $20 billion.

Revenue Models Under the Microscope: Can Fees Alone Justify $20 Billion?

Kalshi charges 2–5 basis points per trade side plus a 0.25% settlement fee, yielding blended take-rates near 0.35%. With disclosed notional of $1.3 billion for 2024, gross revenue reached roughly $4.5 million. Polymarket applies a 1% liquidity-taker fee and 2% market-making spread capture, generating an estimated $27 million on $2.7 billion volume, according to two venture analysts who scraped on-chain flows.

Path to scale

Management teams tell investors take-rates can double without hurting volumes because bettors value certainty and low slippage. Even so, a 0.7% Kalshi take-rate on a projected $10 billion 2025 volume equals $70 million—still implying 285× revenue multiple at $20 billion equity value, far above fintech comps.

Profitability is distant. Kalshi’s EBITDA margin was -95% in 2024 due to $25 million legal and compliance spend; Polymarket’s offshore structure keeps costs leaner but still negative, insiders say. Both firms forecast breakeven at $50 billion annual volume, a threshold that assumes U.S. regulatory clarity and successful European expansion.

Alternative revenue—selling data feeds to polling firms and hedge funds—could add $15 million yearly by 2026, but requires building API infrastructure and enterprise-sales teams. Without new products, skeptics argue, present fee ceilings make today’s $20 billion valuation a lottery ticket on politics rather than a discounted-cash-flow asset.

Which Platform Will Win the Prediction-Market Crown?

Kalshi’s regulatory license offers institutional credibility: hedge funds can trade on margin, compliance officers approve counter-party risk, and Fortune 500 companies hedge weather or Fed outcomes. But the license also constrains product velocity—each new contract needs CFTC review, a 45-day process that can miss trending topics.

Polymarket’s global liquidity edge

Polymarket lists contracts within hours, capturing viral moments from celebrity lawsuits to earthquake magnitudes. Its global user base supplies 24-hour liquidity, whereas Kalshi’s 4 p.m. ET close can create gaps. Yet offshore status keeps U.S. banks and brokers away, limiting block-trade size and advertising channels.

Technology differs too. Kalshi runs on traditional matching-engine architecture co-located with Nasdaq; Polymarket uses smart-contract escrow on Polygon, enabling instant settlement but exposing users to bridge hacks that drained $2 million in 2023. Neither model has proven clearly superior on cost or speed.

Investors backing the $20 billion rounds must pick which constraint—regulatory friction or jurisdictional risk—resolves faster. If the U.S. adopts a permissive framework, Kalshi’s moat widens; if regulators clamp down, Polymarket’s offshore flexibility could vacuum displaced liquidity and validate its lofty valuation.

What Happens Next: Scenarios for Investors and Users

Scenario planners at three venture funds sketched four paths. In the ‘Blue-Sky’ case, a friendly CFTC vote and bipartisan Congressional clarity allow Kalshi to list sports contracts, pushing combined 2026 volume past $30 billion; both platforms IPO at $40 billion, generating 2× returns for late-stage investors.

Gray-sky risks

A split decision—CFTC bans political contracts but allows economic ones—would cut Kalshi volume 35%, but Polymarket could still face U.S. ad-blocking, trimming valuations to $12–15 billion. A full ban would push activity offshore, benefiting Polymarket but risking 40% of its user base if major ISPs restrict access; valuations could retreat to $7–8 billion.

Black-swan tail risks include a high-profile market-manipulation scandal, a smart-contract exploit exceeding $100 million, or an election outcome contested through prediction-market odds. Any could spark Congressional hearings and sweeping prohibitions, vaporizing the $20 billion valuations and leaving investors with illiquid stakes.

Execution will matter. Kalshi must scale beyond politics; Polymarket must prove durability in bear markets. The next funding rounds, likely closing by Q2 2025, will test whether enough limited partners believe the upside scenarios outweigh the existential ones.
