800 000 000 злотых, в ценах 1971 г.
Two independent sources cite the final construction cost as approximately 800 million old Polish zloty (PLZ, pre-1995 redenomination), compared to an initial budget of 200 million zloty. The overrun was caused by an 18-month construction halt due to underground coal deposits threatening structural stability. The figure appears in the English Wikipedia infobox (~800 million zł) and is confirmed by whitemad.pl's 50th-anniversary article on the Spodek ("200 million PLN was earmarked for the investment, but the final cost was around 800 million PLN"). Both sources use the pre-redenomination zloty amounts.
