Why Did the WSOP Main Event Not Reach 10,000 Entrants?

The 2026 World Series of Poker Main Event attracted 9,208 entries, falling 792 players short of the 10,000 needed for “Yes” traders to win on one of Kalshi’s first major poker prediction markets.

Although the turnout represented a second consecutive annual decline, the tournament still generated an $85.6 million prize pool and became the fourth-largest Main Event in WSOP history.

The final result also concluded a prediction market that became significantly more popular as the WSOP approached. When I first examined the market in May for PokerNews, approximately $26,000 had been traded. By the time the market settled, total volume had reached $433,029.

Trading volume on this market increased by more than $407,000, or roughly 1,565%, since we first covered it in May.

How the Kalshi Market Went From Optimistic to likely “No”

Early traders were relatively optimistic. On January 27, the market assigned a 62% implied probability to the Main Event surpassing 10,000 entries, although only around $1,500 had been traded at the time.

The contract then experienced several significant swings as traders reacted to new information. When the complete 2026 WSOP schedule was released in February, “Yes” moved from approximately 48% to 53%. By early May, however, the average “Yes” price had fallen to around 46 cents, and it dropped toward 35 cents after registration opened through the WSOP+ app.

When PokerNews covered the market on May 11, traders gave the Main Event roughly a one-in-three chance of exceeding 10,000 entries.

The probability continued moving as registration figures from earlier WSOP events became available. Lower turnout across several comparable tournaments initially pushed the price down, although “Yes” briefly recovered above 30% shortly before the Main Event began.

That optimism disappeared once the four starting flights began reporting smaller fields than their 2025 equivalents. The implied probability crashed to approximately 4% before registration officially closed.

How Does 2026 Compare to Previous WSOP Main Events?

The Main Event broke the 10,000-entry barrier for the first time in 2023 before setting another record in 2024. Attendance has now declined in each of the two years since.

The 2026 field was 527 entries smaller than the 2025 tournament, representing a year-over-year decline of approximately 5.4%. It was also 904 entries below the record set in 2024.

Still, describing the tournament as poorly attended would be misleading. Before 2023, no Main Event had ever reached 10,000 entries. The 2026 field remained larger than every Main Event held before the recent record-breaking run.

The tournament has now surpassed 9,000 entries in four consecutive years.

Why Didn’t the Main Event Reach 10,000 Entries?

There is no single confirmed explanation for the decline, but the daily registration figures show that the tournament was behind last year from the beginning.

All four Day 1 starting flights attracted fewer players than their 2025 equivalents. The largest difference came on Day 1d, traditionally the most popular starting flight, which declined from 4,997 entries in 2025 to 4,694 this year.

Late registration on the two Day 2 sessions was stronger than last year, but it was not enough to erase the deficit created during the opening flights.

The decline was also not limited to the Main Event. Several major live poker tournaments experienced smaller fields earlier in 2026, including the WPT Seminole Hard Rock Poker Showdown, EPT Monte Carlo Main Event and MSPT FireKeepers Main Event.

Travel may have been another factor.

In my original analysis of the market, international travel, accommodation costs and geopolitical tensions were identified as possible risks to attendance. Players travel to Las Vegas from around the world, meaning even a relatively small reduction in international participation can remove hundreds of potential entries from the field.

Those concerns appeared to have at least some basis during the Series. A June 11th PokerScout analysis compared eight roughly comparable WSOP events from 2023 and 2026. It counted non-American players among each event’s top 100 finishers. Six of the eight events had fewer international top-100 finishers in 2026; one had more, and another was nearly unchanged.

It was also acknowledged that the top 100 may not represent the full field.

The report pointed to tighter travel restrictions, political tensions between the United States and countries such as Canada, and concerns among some international visitors about entering the country.

The 2026 FIFA World Cup may also have competed for international travelers’ attention and recreational budgets. The tournament overlapped with most of the WSOP, while increased demand for flights to the United States potentially made summer travel more expensive.

It is impossible to determine exactly how many poker players chose the World Cup over Las Vegas, but the unfortunate overlap created another obstacle for a tournament attempting to attract a record international field.

Poker Prediction Market Finds an Audience

The final entry count may have disappointed WSOP organizers hoping to return above 10,000, but the prediction market itself appears to have been a success in terms of engagement.

A $433,000 market remains small compared with Kalshi’s largest political and sports contracts, but it is substantial for niche markets outside of classic categories.

It seems likely more poker markets could follow in the future.
