SoftBank Group Corp.'s Vision Fund, according to a report from Forbes, is in negotiations to lead a new $150 million investment round into Missouri-based startup EquipmentShare. Forbes said it is basing its report on a review of prospectus documents. EquipmentShare, which is an equipment rental marketplace that also provides telematics and equipment utilization services, has had sales this year five times higher than the last and is expected to double that next year. A $150 million round would give the company a valuation of at least $1.5 billion and bring EquipmentShare's total fundraising to $220 million. One offer used a $1.7 billion valuation, but there is no indication whether that was from SoftBank or another investor, according to Forbes.
