Trading in shares of the Nordic stock exchange OMX, which is being fought over by Nasdaq and Borse Dubai, were suspended Wednesday afternoon amid speculation that the rival bidders would announce a deal on Thursday. The FT reported Wednesday that Borse Dubai had emerged as a last-minute bidder for Nasdaq’s 31% stake in the London Stock Exchange. Nasdaq, which is trying to sell the stake to help finance its bid for OMX, was previously thought to be close to selling its stake to Qatar Investment Authority for about £14 a share, netting nearly £1bn ($2bn) on its purchase.
