New prediction markets ETF allocates 15% to Kalshi and Polymarket

3 hours ago 13

A new exchange-traded fund wants to give everyday investors a way to bet on the booming business of betting itself. Tema is preparing to launch a prediction markets ETF that carves out 15% of its holdings for Kalshi and Polymarket, the two biggest names in the fast-growing prediction markets space, according to a post from ETF analyst Eric Balchunas on X. The fund won’t touch actual event contracts, though — those remain tangled up in an ongoing SEC review, and that single detail says a lot about how cautiously Wall Street is approaching this corner of finance.

Key takeaways

Tema is launching a prediction markets ETF with 15% exposure to private companies Kalshi and Polymarket.
The fund skips actual event contracts entirely because they’re still under SEC review.
The ETF’s fee is set at 75 basis points.
Tema’s approach leans on the illiquidity bucket of thematic ETFs to justify holding private company stakes.
The launch could pull fresh investor attention toward Kalshi, Polymarket, and the broader prediction markets sector.

Tema Introduces a Prediction Markets ETF Built Around Private Company Stakes

Instead of trading contracts tied to elections, sports outcomes, or economic data, this ETF takes a step back and invests in the companies running those markets. Kalshi and Polymarket together make up 15% of the portfolio — a meaningful bet on the infrastructure behind prediction markets rather than the wagers themselves.

Both companies are privately held, which makes this structure somewhat unusual for a retail-facing ETF. Tema’s strategy treats that illiquidity as a feature rather than a bug, framing it as an opportunity within what the fund manager describes as the illiquidity bucket typically found in thematic ETFs. That’s a niche corner of fund design where less-liquid, harder-to-access assets get bundled into a wrapper that trades freely on public exchanges.

Why Private Company Exposure Matters Here

Retail investors generally can’t buy shares in Kalshi or Polymarket directly since neither company is publicly traded. By wrapping a 15% stake into a fund, Tema effectively opens a side door for public market investors who want exposure to the prediction markets boom without waiting for an IPO that may or may not ever happen.

Regulatory Caution Shapes What the ETF Can Actually Hold

The SEC’s ongoing review of event contracts is the reason this fund stops short of offering direct access to prediction markets themselves. Event contracts — the actual betting instruments used on platforms like Kalshi — sit in a regulatory gray zone, and Tema chose not to build a product around assets that could face rule changes or restrictions down the line.

That decision reflects a broader pattern across the ETF industry right now: fund managers want in on prediction markets’ momentum, but they’re structuring products around the companies and infrastructure rather than the contracts themselves until regulators settle the bigger questions. It’s a workaround that lets Tema launch now instead of waiting on Washington.

What Happens If the SEC Changes Course

Because the fund’s private-company exposure is separate from the event contracts under review, a future SEC decision on those contracts wouldn’t necessarily force Tema to restructure the ETF. Still, any shift in how regulators treat Kalshi or Polymarket as businesses — rather than just their contracts — could ripple into how the fund is valued and marketed.

Fee Structure and What It Signals About Investor Demand

Tema set the fund’s fee at 75 basis points, a rate that sits in line with other specialized thematic ETFs rather than a bargain-bin index fund. That pricing suggests Tema expects investors willing to pay for niche, hard-to-replicate exposure rather than broad market beta.

Whether that bet pays off depends heavily on how much appetite exists for prediction markets as an investment theme rather than just a betting pastime. Balchunas’ announcement alone generated buzz across trading circles, hinting that a segment of investors is eager for a regulated, exchange-traded way to ride the sector’s growth — even if this particular Tema ETF launch doesn’t let them wager on outcomes directly.

What This Means for the Prediction Markets Sector

This launch arrives at a moment when the broader crypto and derivatives markets are sending mixed signals, with trader sentiment swinging depending on the asset. Against that backdrop, a fund tied to Kalshi and Polymarket gives institutional-style exposure to a sector that’s largely been the domain of retail bettors and crypto-native traders until now.

If demand holds up, this could nudge other fund managers to build similar products — perhaps expanding beyond a 15% allocation or finding ways to layer in exposure once the SEC event contracts review reaches a conclusion. For now, though, Tema’s approach is a hedge of its own: enough exposure to capture upside if prediction markets keep growing, without stepping into the regulatory uncertainty still surrounding the contracts that make those markets tick.

Traders and fund watchers will likely track two things going forward — how the SEC ultimately rules on event contracts, and whether investor interest in Kalshi and Polymarket translates into real inflows for this Kalshi Polymarket ETF once it starts trading.
