The global financial landscape has shifted into a new era of "Information Finance," or InfoFi, where the most valuable commodity is not gold or oil, but the "truth." As of February 5, 2026, the battle for dominance in this sector has narrowed down to two titans: Polymarket, the decentralized, crypto-native pioneer, and Kalshi, the regulated, Wall Street-compliant exchange. This rivalry, often dubbed "The Great Prediction War," has evolved from a niche betting experiment into a multi-billion-dollar infrastructure that now dictates the narrative of global politics and economics.

Current sentiment on Manifold Markets reflects the high stakes of this struggle. Traders are currently pricing Polymarket at a 47% probability to hold the title of the world’s leading prediction engine by the end of 2026, while Kalshi trails at 34%. This divergence highlights a fundamental debate among forecasters: whether the future of prediction markets lies in the permissionless liquidity of the blockchain or the structured safety of regulated finance.

The Market: What's Being Predicted

The central question currently captivating traders is which platform will claim the "Volume Crown" for 2026. For the week ending February 1, 2026, the combined trading volume across both platforms hit a staggering $6.32 billion, a record high that reflects the growing mainstream adoption of event contracts. While the market share is currently split nearly down the middle—with Kalshi holding a slight 51/49 edge in raw volume—the composition of that volume tells a different story.

Kalshi’s volume is heavily bolstered by its expansion into the sports betting sector, where it cleared over $43.1 billion in 2025. Conversely, Polymarket, which ended 2025 with $33.4 billion in volume, remains the undisputed king of "high-signal" events. Its markets on geopolitics, macroeconomic shifts, and scientific breakthroughs attract a different class of high-conviction traders. The Manifold Markets contract specifically excludes "pure sports betting" from its resolution criteria, which explains why Polymarket remains the favorite despite Kalshi’s larger total footprint.

Why Traders Are Betting

The 2024 U.S. Presidential Election was the "Netscape moment" for this industry, proving that prediction markets could provide more accurate, real-time data than traditional polling. Polymarket famously outpaced mainstream media in 2024, handling $3.7 billion on the election outcome alone. Since then, the platform has sought to solidify its lead by aggressively expanding its reach. In a major strategic move in late 2025, Polymarket completed a $112 million acquisition of QCEX, a CFTC-licensed exchange, allowing it to legally re-enter the U.S. market and compete head-to-head with Kalshi on American soil.

Meanwhile, Kalshi has leveraged its status as the "regulated incumbent" to integrate with mainstream brokerage giants like Robinhood (NASDAQ: HOOD). By early 2026, the Robinhood "Prediction Markets Hub" has become a massive funnel for Kalshi, processing billions of contracts for retail users who prefer the simplicity of a bank transfer over the complexities of crypto wallets. However, Kalshi has faced its own hurdles, most notably a recent preliminary injunction in Massachusetts that effectively banned it from offering sports-related contracts in the state, labeling them unlicensed gambling.

Broader Context and Implications

The prediction war is no longer confined to the platforms themselves; it has drawn in the largest players on Wall Street. The Intercontinental Exchange (NYSE: ICE), the parent company of the New York Stock Exchange, signaled its endorsement of the sector with a $2 billion investment into Polymarket in late 2025. Simultaneously, Interactive Brokers (NASDAQ: IBKR) has captured a significant portion of the institutional hedging market through its ForecastEx platform, which offers yield on open positions—a feature that attracts corporate treasurers looking to hedge against interest rate fluctuations or climate risks.

Regulatory sentiment has also shifted dramatically under the new leadership of the CFTC. The focus has moved from "prevention" to "oversight," as policymakers realize that these markets offer a public utility: an unbiased, real-time gauge of public sentiment. This "truth engine" model is increasingly seen as a necessary antidote to misinformation and the decline of traditional media credibility. However, the legal landscape remains a patchwork, with Polymarket facing recent bans in France and Singapore, highlighting the ongoing tension between global, decentralized protocols and national jurisdictions.

What to Watch Next

As we move toward the 2026 midterm elections, all eyes will be on how these platforms handle the influx of political volume. A key milestone to watch is the anticipated launch of a native prediction market by Coinbase (NASDAQ: COIN) in late Q1 2026. Coinbase’s entry could potentially disrupt the duopoly, as it possesses both the crypto-native user base of Polymarket and the regulatory licenses to operate within the U.S.

Additionally, traders are monitoring the "Nevada Restraining Order" against Polymarket, which was issued by the state's Gaming Control Board in late January. The resolution of this legal skirmish will likely set a precedent for how individual states interact with federally licensed prediction exchanges. If Polymarket can navigate these state-level challenges as effectively as it has the national ones, its path to the 2026 Volume Crown seems increasingly secure.

Bottom Line

The battle between Polymarket and Kalshi is more than a fight for market share; it is a clash of philosophies. Polymarket represents the "Bloomberg of the Blockchain"—a global, high-signal network that rewards conviction and expertise. Kalshi, meanwhile, is the "Robinhood of Events," aiming to democratize event trading by making it as safe and accessible as buying a share of stock.

While Kalshi currently holds the lead in raw numbers due to its sports-heavy volume, the market’s betting odds favor Polymarket’s dominance in the "Information Finance" space. As we approach the mid-point of 2026, the real winner may be the public at large, who now have access to a sophisticated, real-time mirror of the world's collective expectations. Whether the future is decentralized or strictly regulated, the prediction market has officially become the world's most vital source of truth.
