Tech-inspired speculators from Elon Musk to ordinary retail investors have shaken up commodities, cryptocurrencies and stocks this year, forcing institutions and regulators to reassess how they may impact markets.

In the latest example, Tesla disclosed today it had invested $1.5bn in bitcoin and plans to begin accepting it for payment for its electric cars, creating a rally in bitcoin to a record high of $44,100. Tesla said it purchased the bitcoins after changing its investment policy last month to “diversify and maximise” returns on its cash. Elon Musk has promoted both bitcoin and Dogecoin in recent days.

Meanwhile, hedge funds Two Sigma Investments and DE Shaw are nursing significant losses after an army of retail investors on Reddit upended the markets buying stocks such as GameStop. There are also concerns in Washington about how Wall Street market makers paid almost $3bn to retail brokers such as the Robinhood app to supply them with orders from retail investors for shares or options last year. Lex says this “payment for order flow” could represent a conflict of interest. Robin Wigglesworth comments GameStop could be emblematic of an inflection point for financial markets, with a new era of retail trading emerging.

In her column, Rana Foroohar says claims that the markets have been “democratised” and that people trading on their phones somehow represent a more inclusive capitalism are simply false. She argues: “Markets and democracy are not the same thing.” Rather, the furore around GameStop reflects a fundamental shift in the American economy from one in which prosperity was based on secure employment and income growth, to one in which companies and many consumers focus increasingly on ever-rising asset prices as the most important measure of economic health.

Alphaville was entertained as usual by the slide deck, this time showing a goose laying golden eggs.

4. Renesas in deal for DialogRenesas Electronics is to buy Apple supplier Dialog for €4.9bn in the latest deal by the acquisitive Japanese group aimed at expanding its chip portfolio beyond cars. Lex says that Dialog — US-founded, UK-domiciled and Frankfurt-traded — is no national champion to be defended and the deal looks likely to go ahead, as part of a wider consolidation in the semiconductor industry.

5. Hyundai says no Apple car talksHyundai Motor and its affiliate Kia said they are not in talks with Apple about developing autonomous vehicles, disappointing investors who sent shares in both South Korean carmakers lower.

The British tech entrepreneur Mike Lynch will this week begin his fight against extradition to the US, in the biggest test yet of whether British courts are willing to block the transfer of executives to face justice.
