1. Uber's CEO is out: Travis Kalanick has resigned as the chief executive of Uber.
The move comes after the co-founder failed to defuse a growing crisis over his leadership and demands from investors that he resign from the $68 billion startup.
"I love Uber more than anything in the world and at this difficult moment in my personal life I have accepted the investors request to step aside so that Uber can go back to building rather than be distracted with another fight," he said in a statement late Tuesday.
The startup had brought in former U.S. Attorney General Eric Holder to investigate allegations that its managers didn't adequately address reports of sexual harassment.
His recommendations, published last week, included reevaluating Kalanick's responsibilities at the company and boosting the board's independence.
2. Saudi shake up: Saudi Arabia's king has removed his nephew as crown prince and replaced him with his son, Mohammed bin Salman bin Abdulaziz.
Mohammed bin Salman, who has spearheaded the kingdom's economic reform plans, will now be first in line to succeed King Salman as ruler of the key U.S. ally.
His plan, dubbed Vision 2030, includes selling part of Aramco, the world's top oil producer.
The move comes amid a major diplomatic crisis in the Middle East that has seen Saudi Arabia and its allies seek to isolate the tiny Gulf country of Qatar.
3. U.K. parliament opens: Prime Minister Theresa May will set out her legislative priorities as part of the State Opening of Parliament on Wednesday.
May has been badly bruised after losing her majority in an election two weeks ago.
The prime minister called the election in hopes of strengthening her position, but she now depends on the support of a fringe party as crucial Brexit negotiations with the EU get underway.
Getting her legislative agenda through parliament will be a crucial test of May's leadership.
4. Oil jitters: Investors will be closely watching for new oil market data on Wednesday after crude futures slipped into bear market territory.
The main worry is continued oversupply.
"The challenge is well understood -- OPEC-led output restraint and the current price levels have not been sufficient to reduce global oil supply enough to make a dent into inventory levels," Kit Juckes, strategist at Societe Generale, wrote in a note to clients.
Data on crude inventories in the U.S. will be published at 10:30 a.m. ET. Oil declined 0.5% to trade at $43.30 per barrel.
5. Global market overview: U.S. stock futures were trading lower early on Wednesday.
European markets opened down, while markets in Asia finished the session mixed.
