Top Prediction Markets Ranked Across Five English-Speaking Markets

Top Prediction Markets Ranked Across Five English-Speaking Markets

Blask has published a top 10 ranking of prediction markets across the US, Canada, the UK, Australia, and Ireland. The list uses BAP, short for Brand's Accumulated Power, a market share based metric designed to track brand strength within each geography.

The results show a highly concentrated sector. Polymarket leads in all five markets, while Kalshi sits in second place throughout. Beyond those two brands, the remaining field holds only marginal shares, signalling a market where scale and recognition matter far more than breadth of competition.

How The Rankings Break Down

In the US, Polymarket leads with 67.15%, followed by Kalshi on 28.04%. DraftKings ranks third on 2.67%, with Myriad, Manifold, Robinhood, Novig, PredictIt, IBKR, and Opinion completing the top 10.

Canada shows even stronger concentration. Polymarket reaches 90.02%, while Kalshi records 8.16%. Manifold and Myriad both remain below 1%, and the rest of the table holds only fractional shares.

In the UK, Polymarket stands at 94.2% and Kalshi at 4.44%. Manifold and Myriad follow with less than 1% each, showing that the market is overwhelmingly concentrated around one dominant brand.

Australia is the most competitive market after the US. Polymarket posts 67.49%, and Kalshi reaches 30.33%. Myriad and Manifold both stay near 1%, while the rest of the list remains negligible.

Ireland delivers the most decisive lead. Polymarket commands 95.07%, with Kalshi on 4.03%. Every other brand sits below 1%, including DraftKings, which only just enters the top 10.

What BAP Means For Industry Watchers

BAP measures Brand's Accumulated Power, which Blask describes as a composite indicator based on market share. In practical terms, it gives operators and suppliers a fast view of which brands have already secured attention and repeat usage in a given market.

That matters because prediction markets rely heavily on liquidity and trust. Users tend to prefer platforms where pricing feels efficient and contracts attract enough participation. Once a brand reaches critical mass, smaller rivals face a much harder path to visibility.

Why This Matters For Operators And Suppliers

The rankings point to a two tier market. Polymarket and Kalshi occupy the meaningful competitive space, while the rest of the field is fighting for very small slices of demand. For operators, that raises the cost of entry. For suppliers, it increases the value of differentiation in pricing tools, user experience, and market coverage.

The data also shows that geography still shapes opportunity. The US and Australia leave more room for rivalry between the top two brands, while Canada, the UK, and Ireland are far more concentrated. That gap can influence acquisition strategy, partnership priorities, and product localisation.

A Market Defined By Concentration

The headline from Blask's ranking is clear. Prediction markets across these five English-speaking geographies are not evenly distributed. One brand dominates every list, one challenger is consistently relevant, and everyone else remains at the edge of the category.

For B2B stakeholders, this creates a simple read on the sector. Growth will come from winning liquidity, retaining user trust, and tailoring products to the regulatory and cultural realities of each market. Brand power is already shaping the leaderboard.
