Plus500 Stock up 6% Since Kalshi Partnership
Fintech provider Plus500 announced a partnership with Kalshi on Tuesday.
Through that partnership, the company will offer event contracts through its U.S. platform, Plus500 Futures. Those event contracts are powered by Kalshi’s trading infrastructure. Plus500 is also the clearing member of Kalshi’s clearinghouse, Kalshi Klear.
Plus500 Group CFO Elad Even-Chen wrote on LinkedIn:
“This marks a pivotal moment for Plus500. Prediction markets are the fastest growing asset class in the world with demand accelerating from both retail and institutional. Like we’ve done in traditional assets, Plus500 intends to play a leading role in this industry as well.”
Plus500’s stock rose 9.72% over the past five days. On the day of Plus500’s announcement, the company’s stock rose 6% in the first hour of trading.
Prediction market frenzy continues
Plus500 isn’t the only company whose stock price has risen after a major prediction market announcement. High Roller saw a 577% increase in its stock price after announcing its Crypto.com deal in January 2026.
These stock impacts are part of a greater enthusiasm for prediction markets. Polymarket was valued between $12 billion and $15 billion in January 2026. Kalshi completed a $1 billion raise at an $11 billion valuation in December 2025.
Investors are flocking to prediction markets for their uses in hedging, forecasting, and the potential to reach many new retail traders.
Legal challenges haven’t slowed momentum
Prediction market platforms and brokers remain in conflict with state regulators over sports contracts. However, Circuit Courts have yet to release an opinion regarding state authority over sports contracts that appear to conflict with state sports betting law.
CFTC Chairman Michael Selig has expressed support for sports contracts and the CFTC’s exclusive jurisdiction over event contracts. During his joint appearance with SEC Chairman Paul Atkins, Selig announced his intention “reevaluate” the CFTC’s participation in event contract litigation.
The CFTC has not filed amici curiae briefs in Kalshi, Robinhood, or any other state cases against federally regulated prediction market platforms. That support seems to be giving investors confidence that prediction markets will remain above board regardless of state gaming regulators’ objections in the near-term.
