Google has been moderating and removing employees’ internal election-related conversations, CNBC has learned. 

Ahead of Tuesday’s U.S. elections, Google executives warned employees to keep political opinions and statements away from a popular internal discussion forum called Memegen, according to correspondence viewed by CNBC. Despite the warnings, employees continued posting memes related to the election and criticizing the company’s policies on Tuesday.

The most recent leadership guidance shows the company is taking expanded action to temper internal political discussions. Google CEO Sundar Pichai on Monday sent a memo reminding employees that people turn to the company’s services for “high-quality and reliable information.” That includes through the company’s Google Search, Google News and YouTube services.

“Whomever the voters entrust, let’s remember the role we play at work, through the products we build and as a business: to be a trusted source of information to people of every background and belief,” Pichai wrote. “We will and must maintain that.”

As one of the most important tech leaders in the U.S., Pichai himself has been pulled into the broader political discussions of late. Republican nominee Donald Trump claimed to have multiple phone calls with Pichai in recent weeks.

Google has been cracking down on internal conversations since 2019 when the company introduced a policy barring employees from making statements that “insult, demean, or humiliate” their colleagues. The rules also discouraged employees from engaging in a “raging debate over politics or the latest news story.”

That policy signaled a significant culture shift for the company. Some employees pushed back against the restrictions, saying they were too broad, and in 2020, the company said it was expanding its internal content moderation practices, requiring employees to more actively moderate internal discussions, CNBC found at the time.

Since 2021, Google has dealt with internal dissent regarding Project Nimbus, which is a $1.2 billion joint contract with Amazon to provide the Israeli government and military with cloud computing and AI services. Google briefly shut down an internal message board this March after employees posted comments about the company’s Nimbus contract.

In a 2019 settlement, the U.S. National Labor Board ordered Google to post a list of employee rights at its headquarters that included the right to discuss workplace conditions. That came after a former Google employee filed a complaint alleging that the company restricted free speech and fired him for expressing conservative views, which Google refuted.

The company declined to comment.

Perplexity AI, the artificial-intelligence search engine startup, is in the final stages of raising $500 million in funding at a $9 billion valuation, a source familiar with the situation told CNBC.

The startup competes against the likes of Google and ChatGPT-maker OpenAI. Perplexity most recent valuation was $3 billion in June. Institutional Venture Partners, a Bay Area-based firm, is leading the new round, according to the source, who requested anonymity since the funding is not yet public.

Perplexity started the year with a roughly $500 million valuation. Since then, the company has continued to attract investor interest amid the generative AI boom, raising four funding rounds so far this year.

Last week, OpenAI launched a search feature within ChatGPT, its viral chatbot, that positioned it to better compete with Perplexity, as well as leading search engines like Google and Microsoft‘s Bing. OpenAI’s search feature offers up-to-the-minute sports scores, stock quotes, news, weather and more, powered by real-time web search and partnerships with news and data providers, according to the company.

Despite the AI boom, Perplexity has been embroiled in controversy due to accusations of plagiarizing content from media outlets. The New York Times last month sent Perplexity a “cease and desist” notice, claiming that the startup scrapes the news outlet’s content to generate answers. Perplexity has denied the allegations.

In July, Perplexity debuted a revenue-sharing model for publishers. Any time a user asks a question and Perplexity generates ad revenue from citing an article in its answer, Perplexity will share a percentage of that revenue with the publisher, the company said.

Media outlets and content platforms including Fortune, Time, Entrepreneur, The Texas Tribune, Der Spiegel and WordPress were among the first to join the company’s “Publishers Program.” Dmitry Shevelenko, Perplexity’s chief business officer, told CNBC in a July interview that if three articles from one publisher were used in one answer, the partner would receive “triple the revenue share.” Perplexity worked on its revenue-sharing model since January, and the company’s goal is to have 30 publishers enrolled by the end of the year, Shevelenko said.

Perplexity’s app has been downloaded more than 2 million times, and it answers more than 230 million queries a month, the company said in August. U.S. queries have increased eightfold in the past year, according to a pitch deck for potential advertisers that was viewed by CNBC.

The Wall Street Journal was first to report on the new funding round.

Cryptocurrencies were slightly higher Tuesday evening as investors waited for direction on the potential outcome of the U.S. presidential election.

The price of bitcoin was last higher by 2% at $69,105.03, according to Coin Metrics. Earlier, it rose as high as $70,522.84. It is currently 5% off its all-time high, after trading near it last week.

Stocks tied to the price of the cryptocurrency got a boost in earlier trading during regular stock market hours. Exchange operator Coinbase and MicroStrategy, which often trades as a high beta play on the price of bitcoin, advanced 4% and 2%, respectively.

Investors are expecting bitcoin trading to be choppy until a clear winner is declared. A victory for Vice President Kamala Harris is expected to bring risk of downside moves to the price of bitcoin, while traders anticipate a bump in price in the event of a win by former President Donald Trump.

“The election is having a massive influence on crypto,” said Ryan Rasmussen, head of research at Bitwise Asset Management. “Expect bitcoin – and crypto more broadly – to be choppy in the days ahead … until we have definitive election results.”

“If Trump wins, I believe we’ll see new all-time highs,” Rasmussen added. “If Harris wins, I expect a decent short-term sell-off, with prices taking a month or two to recover. But eventually, either way, I think we go higher.”

Bitcoin is widely expected to rise to a new record in coming weeks. In the 2012, 2016 and 2020 elections, bitcoin saw returns of roughly 87%, 44% and 145% in the 90 days following election day, respectively. That’s in part because election years happen to fall on Bitcoin halving years, when the supply of the cryptocurrency ratchets downward. Post election returns have also tended to align with major Federal Reserve policy shifts. This year, the market is looking forward to further interest rate reductions.

Earlier Tuesday, bitcoin wavered around the $70,000 mark, after hitting that level last week for the first time since March and approaching its record of $73,797.68. At about $69,000, bitcoin has been trading at its fair value price, according to CryptoQuant. That means that if the election proves to be a positive catalyst in the coming days, bitcoin can rally and is poised to establish a new record, CryptoQuant analyst Julio Moreno said.

“For now, everyone we’ve spoken to is keeping their powder dry,” said James Davies, CEO at crypto futures and options trading platform Crypto Valley Exchange. “I’ve heard from numerous leading market makers and traders and can say with conviction that almost everyone is set up to react. They don’t even know which way markets will go based on [the] result. There’s likely to be massive short-term volatility whichever outcome.”

This year’s presidential election has been called the most important one in the crypto industry’s lifetime. Many view a Harris win as a threat to crypto, the extent to which has been debated throughout this election cycle. Trump, on the other hand, is seen by many as a force for good in the industry after he presented himself earlier this year as the pro-crypto candidate and has been courting the industry more directly than Harris has.
