Uber announced Wednesday it raised $3.5 billion from the Public Investment Fund of Saudi Arabia to fuel global expansion plans

Uber announced Wednesday that the Public Investment Fund of Saudi Arabia has pumped $3.5 billion into the ride-sharing giant, helping fuel its global expansion plans.

Terms of the investment give what was already one of the largest venture-funded startups a valuation, or implied value, of $62.5 billion, according to the company.

The deal comes as Saudi Arabia strives to diversify its economy away from reliance on oil production to include more entrepreneurship, open markets and productivity.

The new funding also helps Uber's global expansion, including in the Middle East and North Africa, which the company see as among its fastest-growing regions.

In addition to the investment, which will boost Uber's cash holdings to more than $11 billion, the head of the Saudi fund, Yasir Al Rumayyan, is joining the Uber board.

"We appreciate the vote of confidence in our business as we continue to expand our global presence," Uber chief executive Travis Kalanick said in a statement.

"Our experience in Saudi Arabia is a great example of how Uber can benefit riders, drivers and cities and we look forward to partnering to support their economic and social reforms."

Rumayyan said in a statement that the fund "is excited to have completed this important strategic investment with Uber, an extraordinary company with an inspiring mission."

He added that the plan fits with the kingdom's Vision 2030, the blueprint for diversifying its economy away from oil.

According to Uber, the company is committed to investing $250 million in the region, which includes Egypt, Saudi Arabia, United Arab Emirates, Israel, Jordan, Lebanon, Bahrain, Qatar and Morocco.

In Saudi Arabia, around 80 percent of Uber's riders are women, the company said, explaining that the service can help improve mobility for women, who cannot drive in the country and typically avoid public taxis.

Egypt tightens reins

Egypt in March said it will regulate ride-hailing services Uber and Careem after they sparked protests by taxi drivers in Cairo over allegations the smartphone apps bypass regulations.

Cab drivers contend that not only are they losing clients to Uber and Careem, but the two services use vehicles that are unregistered for ferrying commuters.

Egypt's cabinet said the authorities would take steps to regulate the two ride-hailing services.

Uber and Careem drivers would "have to pay taxes" and their apps would need to establish a "suitable framework for traditional taxi drivers to join them," the cabinet maintained.

San Francisco-based Uber has expanded to hundreds of cities worldwide, despite complaints from established taxi operators and regulators.

Eyes on oil

Saudi Arabia's push to diversify away from oil comes amid a significant global oversupply.

OPEC, which pumps about a third of the world's crude, has contributed to the chronic problem, led by kingpin Saudi Arabia.

Some OPEC ministers expressed hope that the oil market would improve in the second half of the year after prices took a beating from abundant supplies as the Organization of the Petroleum Exporting Countries prepared to open its biannual meeting Thursday in Vienna.

However most analysts do not expect the 13-nation cartel will announce any measure to reduce output, especially since prices have rebounded nearly 90 percent from February lows.
