FTX founder Sam Bankman-Fried told jurors in his criminal trial on Friday that he didn’t commit fraud at his crypto exchange, which collapsed late last year.

Bankman-Fried addressed the New York courtroom a day after U.S. District Judge Lewis Kaplan sent jurors home early to consider whether some aspects of the defendant’s planned testimony, related to legal advice he got while running FTX, would be admissible in court.

On Friday morning, defense attorney Mark Cohen asked Bankman-Fried if he defrauded anyone.

“No, I did not,” Bankman-Fried responded.

Cohen followed by asking if he took customer funds, to which Bankman-Fried said “no.”

Bankman-Fried, 31, faces seven criminal counts, including wire fraud, securities fraud and money laundering, that could land him in prison for life if he’s convicted. Bankman-Fried, the son of two Stanford legal scholars, has pleaded not guilty in the case.

Prior to the defendant’s appearance on the stand, the four-week trial was highlighted by the testimony of multiple members of FTX’s top leadership team as well as the people who ran sister hedge fund Alameda Research. They all singled out Bankman-Fried as the mastermind of a scheme to use FTX customer money to fund everything from venture investments and a high-priced condo in the Bahamas to covering Alameda’s crypto losses.

Prosecutors walked former leaders of Bankman-Fried’s businesses through specific actions taken by their boss that resulted in clients losing billions of dollars last year. Several of the witnesses, including Bankman-Fried’s ex-girlfriend Caroline Ellison, who ran Alameda, have pleaded guilty to multiple charges and are cooperating with the government.

The judge’s decision to send the jury home on Thursday allowed Bankman-Fried and his defense team to audition their best legal material for Judge Kaplan.

‘Significant oversights’

On Friday, Bankman-Fried acknowledged that one of his biggest mistakes was not having a risk management team or chief regulatory officer. That led to “significant oversights,” he said.

Cohen walked Bankman-Fried through his background and how he got into crypto. The defendant said he studied physics at the Massachusetts Institute of Technology and graduated in 2014. He then worked as a trader on the international desk at Jane Street for over three years, managing tens of billions of dollars a day in trading. That’s where he learned the fundamentals of things like arbitrage trading.

In the fall of 2017, Bankman-Fried founded Alameda Research.

“This was when crypto was starting to become publicly visible for the first time,” Bankman-Fried testified.

He said people were excited about it, watching bitcoin, which had jumped from $1,000 to $10,000 in a two-month period. Banks and brokers weren’t involved yet and it seemed like there would probably be big demand for an arbitrage provider, he said.

“I had absolutely no idea” how cryptocurrencies worked, Bankman-Fried said. “I just knew they were things you could trade.”

The first Alameda office was in an Airbnb in Berkeley, California, he said. It was listed as a two bedroom but they used the couch in the living room as a third bed and the attic as a fourth.

He started FTX in 2019. Trading volume grew substantially on FTX from a few million dollars a day to tens of millions of dollars that year to hundreds of millions of dollars in 2020. By 2022, that number was up to $10 billion to $15 billion of dollars per day in trading volume, he said.

Bankman-Fried said Alameda was permitted to borrow from FTX, but his understanding was that the money was coming from margin trades, collateral from other margin trades or assets earning interest on the platform.

At FTX, there were no general restrictions on what could be done with funds that were borrowed as long as the company believed assets were greater than liabilities, Bankman-Fried testified.

Sam Bankman-Fried takes the stand

In 2020, a routine liquidation gone wrong led to some of the special borrowing permissions at Alameda, he said. The risk engine was sagging under the weight of growth. A liquidation that should have been in the thousands of dollars was in the trillions of dollars. Alameda was suddenly underwater because of closing the position.

The incident exposed a larger concern, that the potential of an erroneous liquidation of Alameda could be disastrous for users.

Bankman-Fried said he talked to FTX’s engineering director Nishad Singh and co-founder Gary Wang, both of whom testified earlier on behalf of the prosecution. They suggested creating an alert, which would prompt the user to deposit more collateral, or a delay, Bankman-Fried said. They later implemented a feature like that, he said, adding that he learned it was the “allow negative” feature.

Bankman-Fried testified that he wasn’t aware of the amount Alameda was borrowing or its theoretical max. As long as the net asset value was positive on the exchange and the scale of borrowing was reasonable, increasing the line of credit so Alameda could keep filling orders was fine, he said. Bankman-Fried added that he now believes what Singh and Wang did was increase the line of credit.

Tough sell

Convincing the jury will be a tall order for Bankman-Fried after a mountain of damning evidence was presented by the government.

Prosecutors also entered corroborating materials, including encrypted Signal messages and other internal documents that appear to show Bankman-Fried orchestrating the spending of FTX customer money.

The defense’s case, which consists of Bankman-Fried’s testimony along with that of two witnesses who took the stand Thursday morning, hinges largely on whether the jury believes the defendant didn’t intend to commit fraud.

On Thursday, under questioning led by Cohen, Bankman-Fried appeared to place much of the criminal blame on FTX’s chief regulatory officer, Dan Friedberg, as well as outside counsel Fenwick & West, which advised the crypto exchange. Bankman-Fried spoke about Friedberg’s active involvement in everything from the companywide auto-deletion policy on messaging apps like Signal, to the creation of Alameda’s North Dimension bank account, where billions of dollars worth of FTX customer money was funneled.

The former FTX chief also said that the hundreds of millions of dollars in personal loans to himself and other founders of the platform were structured through promissory notes drafted by his in-house legal team and discussed in concert with his general counsel and Friedberg. Having the blessing of his legal counsel was something that SBF said he “took comfort in.”

E-quipment highlight: Komatsu PC365-11 hybrid excavator

Thanks to a clever, fully electric swing system and “boom up” power assist features, the big PC365-11 hybrid excavator from Komatsu promises better performance and serious fuel savings compared to conventional diesel machines.

Komatsu says its PC365-11 hybrid excavator uses a “boom-up” power assist feature that captures and stores kinetic energy during different operation cycles, then taps into that power to provide an extra energy boost when needed. The result is 15% more productivity and a 20% improvement in fuel efficiency when compared to non-hybrid excavators in ~40 ton class.

“The PC365LC-11 was engineered for excellence in multifunction applications by leveraging its innovative electric powertrain system to boost job site productivity while reducing fuel consumption,” says Matthew Moen, Komatsu’s product manager. “To highlight these performance enhancements, we’re emphasizing the concept of ‘multifunction plus’ as the defining feature of this machine.”

How it works


Komatsu hybrid explainer; via Komatsu.

Komatsu’s hybrid system replaces the conventional hydraulic swing function with a fully electric swing motor that draws power from an ultracapacitor (as opposed to a battery) energy storage unit. As excavator slows or stops swinging, something like a regenerative braking system captures the kinetic energy that would normally be lost as heat and stores it in the capacitor. Once there, the stored energy can be quickly released to power the swing motor or assist the engine, delivering up to an extra 70 hp when needed to support heavy lifting or digging cycles.

And, thanks to Komatsu’s proprietary software, all of this energy capture and reuse happens automagically during normal work, without the need for external charging. The fuel savings happen because removing the hydraulic load from the ICE engine allows it to run at an ultra-low idle, while the productivity comes from the greater power and overall speed of the electric operations vs. conventional hydraulics.

Electrek’s Take

Trust me when I tell you that Komatsu didn’t wake up one day and decide to build a capacitor-based hybrid crane. One of their customers had the idea and came to them, promising orders. That’s what Komatsu does – from undersea remote control dozers to lunar mining rigs (above), if you bring Komatsu an order, they will absolutely find a way to fill it.

As for PC365-11 hybrid excavator, it’s packed with clever tech, overall – offering significant fuel, emissions, and TCO reductions without dramatically changing the operational logistics of an existing fleet’s operations. That’s all the sales pitch it needs.

Five for Five: Kia PV5 scores 5 star European safety rating

Five for Five: Kia PV5 scores 5 star European safety rating

For serious fleet buyers, safety isn’t a “nice-to-have,” it’s an absolute must – and Kia’s new PV5 electric van meets that need with a positively stellar, five-star safety rating on the tough European NCAP safety test.

The new “do-it-all” Kia PV5 showed strong performance across a number of key safety categories, including Occupant Protection, Safety Assist/Crash Avoidance, and Post-Crash Safety. The PV5’s robust suite of standard ADAS technologies that includes AEB, Lane Support System, and Speed Assistance System also helped the new electric work van to deliver top marks in the NCAP’s “real world” test scenarios.

The PV5 opens a new chapter in practical, electrified mobility, offering generous space and modular versatility for everyday use,” explains Sangdae Kim, Executive Vice President and Head of the (relatively) new PBV Business Division at Kia. “Achieving the top Euro NCAP five-star rating is clear validation of its safety performance and will serve as strong momentum as Kia expands its PBV lineup across Europe.”

The Euro NCAP tests highlighted the strong performance of a number of the PV5’s ADAS features, specifically calling out the following:

  • Demonstrated strong responsiveness in vehicle-to-vehicle scenarios
  • Provides additional protection for pedestrians behind the vehicle
  • Avoided collisions in most pedestrian and cyclist test cases

The Kia PV5 slots into familiar territory for US buyers, landing roughly in the same size class as the Ford Transit Connect or Ram ProMaster City, with ~180 cubic feet of interior cargo space available, which is plenty to make it attractive for last-mile delivery and trade work in tight urban markets.

Globally, the PV5 is offered with a number of battery options, including a smaller 43.3 kWh Lithium-Iron-Phosphate (LFP) pack, as well as larger Nickel-Cobalt-Manganese (NCM) packs at 51.5 kWh and 71.2 kWh. The longest-range versions are good for about 250 miles of estimated range – more than enough for Kia to make a case for it as a practical, city-focused alternative to much larger (and pricier) electric vans.

Larger vans, by the way, that may not have that 5 star Euro NCAP rating.

Waymo pauses robotaxi service in San Francisco after blackout chaos — Musk says Tesla car service unaffected

Waymo resumes robotaxi service in San Francisco after blackout chaos — Musk says Tesla car service unaffected

Alphabet-owned Waymo has suspended its driverless ride-hail service in the San Francisco Bay Area after blackouts plagued the city Saturday afternoon.

“We have temporarily suspended our ride-hailing services in the San Francisco Bay Area due to the widespread power outage,” a Waymo spokesperson tells CNBC. “Our teams are working diligently and in close coordination with city officials, and we are hopeful to bring our services back online soon. We appreciate your patience and will provide further updates as soon as they are available.”

As power outages spread yesterday, videos shared on social media appeared to show multiple Waymo vehicles stalled in traffic in different parts of the city.

San Francisco resident Matt Schoolfield said he saw at least three Waymo autonomous vehicles stopped in traffic Saturday around 9:45 p.m. local time, including one he photographed on Turk Boulevard near Parker Avenue.

“They were just stopping in the middle of the street,” Schoolfield said.

The power outages began around 1:09 p.m. Saturday and peaked roughly two hours later, affecting about 130,000 customers, according to Pacific Gas and Electric. As of Sunday morning, about 21,000 customers remained without power, mainly in the Presidio, the Richmond District, Golden Gate Park and parts of downtown San Francisco.

PG&E said the outage was caused by a fire at a substation that resulted in “significant and extensive” damage, and said it could not yet provide a precise timeline for full restoration.

San Francisco Mayor Daniel Lurie said in a 9 p.m. update on X that police officers, fire crews, parking control officers and city ambassadors were deployed across affected neighborhoods as transit service gradually resumed. “Waymo has also paused service,” Lurie said.

Amid the disruption, Tesla CEO Elon Musk posted on X: “Tesla Robotaxis were unaffected by the SF power outage.”

Unlike Waymo, Tesla does not operate a driverless robotaxi service in San Francisco.

Tesla’s local ride-hailing service uses vehicles equipped with “FSD (Supervised),” a premium driver assistance system. The service requires a human driver behind the wheel at all times.

According to state regulators — including the California Department of Motor Vehicles and California Public Utilities Commission — Tesla has not obtained permits to conduct driverless testing or services in the state without human safety supervisors behind the wheel, ready to steer or brake at any time.

Tesla is vying to become a robotaxi titan, but does not yet operate commercial, driverless services. Tesla’s Robotaxi app allows users to hail a ride; however, its vehicles currently have human safety supervisors or drivers on board, even in states where the company has obtained permits for driverless operations.

Waymo, which leads the nascent industry in the West, is Tesla’s chief competitor in AVs, along with Chinese players like Baidu-owned Apollo Go.

The outage-related disruptions in San Francisco come as robotaxi services are becoming more common in other major U.S. cities. Waymo is among a small number of companies operating fully driverless ride-hailing services for the public, even as unease about autonomous vehicles remains high.

A survey by the American Automobile Association earlier this year found that about two-thirds of U.S. drivers said they were fearful of autonomous vehicles.

The Waymo pause in San Francisco indicates cities are not yet ready for highly automated vehicles to inundate their streets, said Bryan Reimer, a research scientist at the MIT Center for Transportation and co-author of “How to Make AI Useful.”

“Something in the design and development of this technology was missed that clearly illustrates it was not the robust solution many would like to believe it is,” he said.

Reimer noted that power outages are entirely predictable. “Not for eternity, but in the foreseeable future, we will need to mix human and machine intelligence, and have human backup systems in place around highly automated systems, including robotaxis,” he said.

State and city regulators will need to consider what the maximum penetration of highly automated vehicles should be in their region, Reimer added, and AV developers should be held responsible for “chaos gridlock,” just as human drivers would be held responsible for how they drive during a blackout.

Waymo did not say when its service would resume and did not specify whether collisions involving its vehicles had occurred during the blackout.

Tesla and the National Highway Traffic Safety Administration did not immediately respond to requests for comment.
