Before 2030: Resolves as soon as the underground station opens to the public or if it becomes clear that it will never open. Resolves to “2030 or later” in 2030.
I will not bet on this market.
Stuttgart 21 was officially announced in April 1994. Construction work began on 2 February 2010. In March 2013, total costs were officially estimated at €6.5 billion, the previous estimate being €4.5 billion in 2009. In March 2022, Deutsche Bahn estimated the total cost at €9.15 billion. Heated debate ensued on a broad range of issues, including the relative costs and benefits, geological and environmental concerns, as well as performance issues. In 2019, operations had been expected to start in December 2025, delayed from the initial estimation of 2019 (made in 2010). In 2024, the opening date for main elements of the project was delayed again, to December 2026.
