European Club Football 2026-27

Four of Europe's biggest title boards traded today. On three of them, the busiest contract of the day was priced at half a cent.

Champions League: Como at 0.5% took $30,623—48% of the entire board's $64,283 day, more than twice Barcelona's $13,041 at 22.5%. Como holds $53,749 of open interest, on a board where the favourite holds $342,258.

La Liga: Deportivo de La Coruña at 0.5% took $6,567—50% of a $13,122 day. Barcelona at 61.5% took 21%.

Premier League: Kalshi sends 53% of its day to Liverpool at 6.5% and Chelsea at 14.5%, and Tottenham at 0.5% is its third-busiest name. On Polymarket's mirror, Hull City at 0.35% is the busiest contract on the board outright, taking 23% of the day, with Brentford at 0.45% second.

Bundesliga is the same shape at smaller scale: Dortmund at 8% took 87% of the day and Elversberg at 0.5% took 13%, while Bayern Munich—priced 87.5%—took 1%.

Serie A is the exception. Inter at 53.5% took 46% of the day and the rest of the flow follows the ladder down in roughly the right order. It is the only one of the five boards where the money behaves as the prices would predict.

Where the standing risk sits is a separate question. On Kalshi's EPL board, Chelsea at 14.5% holds the most open interest at $399,594, ahead of Manchester City at 23.5% ($345,875) and Arsenal at 50.5% ($316,537). Tottenham, at 0.5%, holds $291,693—within 8% of the favourite's.

The two boards with the most money behind them. The Champions League holds $1,511,205 and sums to 114%; the Premier League holds $2,496,887 and sums to 107%. Both are quoted sensibly at the top. Both send most of their daily volume somewhere else entirely.

Como against Barcelona on the Champions League board. Barcelona is 22.5% and holds $342,258. Como is 0.5% and took nearly half the board's volume today. Whatever this flow is, it is persistent enough to be the largest single number on the page.

La Liga and Serie A, the divergent pair. La Liga's busiest contract is Deportivo at 0.5%, taking half the day; Serie A's is Inter at 53.5%, the actual favourite. Same league structure, same exchange, opposite flow patterns.

Bundesliga, where Bayern at 87.5% took one percent of the day, and Polymarket's Premier League board, where the two cheapest contracts on the ladder took 36% of it. Polymarket prices Arsenal 48.5% against Kalshi's 50.5%.

The derived Premier League boards. Relegation is the one place a high price attracts the volume—Hull City at 58.5% took 81% of that board. Top goalscorer is orthodox too: Haaland at 63% took 59%. Both are Polymarket books, both sensibly shaped, which makes the title board's behaviour on the same venue harder to explain as a platform artefact.

The domestic seasons run to late May 2027; the Champions League final is June 5, 2027. Nothing on this page settles for eight months, which is precisely why the flow pattern is interesting: none of it is deadline-driven.

Three things to watch:

• Half-cent contracts as the busiest names. Como, Deportivo, Hull City, Tottenham, Elversberg—five boards, five different leagues, and in each the day's volume leader is priced at or near the exchange floor. Long-dated outright boards appear to attract systematically different flow from short-dated event books, and this is the clearest place in the catalog to watch it.
• Open interest versus price on the EPL board. Chelsea at 14.5% holds more paper than Arsenal at 50.5%. That gap has widened, not closed, since this workspace started tracking it.
• The Serie A control case. One board out of five where the money follows the odds. If it stays that way, it is worth asking what is different about it.
