Many people thought that the close relationship between Donald Trump and Elon Musk would end badly, since they both have the hubris that comes from success and power.

One is arguably the most powerful politician in the world and the other the richest man.

That said, most people were not prepared for the rapid breakdown in their relationship and the slanging match that took place after Musk spectacularly fell out with the US president.

This was magnified by the fact that both have their own influential social media sites (X and Truth Social) and so the divorce was very, very public.

More recently Musk has rowed back on the comments he made about Trump after leaving his role as a “special government employee” of the administration, and says he went “too far”. But Trump might have a long memory for grievances, so it remains to be seen if the relationship can be patched up.

What do the American people think? The chart below shows the percentage of respondents with favourable and unfavourable opinions of Trump and Musk in the most recent US Economist/YouGov poll completed on June 9 after the row blew up.

It is clear that the most people think that Trump won the contest, giving him a favourability gap (percentage favourable minus percentage unfavourable) of -10 per cent compared with Musk’s gap of -23 per cent.

What Americans think of Trump and Musk after their row:

The demographics of these favourability judgments are particularly interesting.

After the fight, about 49 per cent of men thought favourably of Trump, compared with 38 per cent of women, continuing a trend that shows more male than female support for the President.

The gender gap for Musk is even wider with 43 per cent men and only 27 per cent women having a favourable view of the billionaire, making the gap 11 per cent for Trump and 16 per cent for Musk.

Another interesting demographic is age.

Some 35 per cent of 18-to-29 year olds favour Trump (the lowest number of any age group), compared with 30 per cent who favour Musk.

The equivalent figures for the over 65s are 45 per cent favouring Trump and 37 per cent Musk.

The age divide is wide, with young Americans disliking both more than older Americans, but it is not as wide as the gender gap.

The income figures and attitudes to both are also surprising.

A total of 38 per cent of those with incomes less than US$50,000 ($70,000) a year favour Trump, compared with 51 per cent of those with incomes between US$50,000 and US$100,000 ($140,000).

The surprise is that only 42 per cent of those with incomes greater than US$100,000 favour Trump, making affluent Americans closer to the low-income group than to the middle-income group in attitudes to the president.

The equivalent figures for Musk are 32 per cent favourable in the US$50,000 group, 39 per cent in the US$50,000 to US$100,000 group and 36 per cent in the US$100,000-plus group, which gives a similar picture.

If we look at the voting record of the survey respondents in the presidential elections last year, 86 per cent of Trump voters still have a favourable view of him, compared with only 5 per cent of Harris voters.

In comparison 67 per cent of Republican voters are favourable to Musk, compared with 10 per cent of Democrats. Equally, 81 per cent of Conservatives favour Trump compared with 67 per cent who favour Musk.

Looking at the overall picture, Musk is the loser in the breakup as far as the American public are concerned, and this may in part explain his apparent contrition.

The price of Tesla shares (US$) since the presidential election:

Overall though, Trump has gradually lost support on his job approval since last year’s US election and the polling shows that 43 per cent of respondents approve and 52 per cent disapprove of his performance as President.

We don’t have equivalent figures for Musk, but if we take the stock market price of Tesla shares as a guide to his approval ratings this has declined rapidly over time as the chart shows.

On December 17 last year the price was US$480 ($740) a share, compared with US$332 ($511) per share on June 11, 2025. This represents a fall of about 30 per cent.

The dramatic dip at the end of the series is an indicator of how markets have reacted to the spat between them.

Following his public break-up with Trump, Musk’s other major company, Space X, is also likely to face fallout. It is a private company and so does not have a share price, but it is heavily dependent on contracts from the US government to keep going.

It seems likely that the flow of contracts for space projects is likely to dry up following the row with Trump, as the President has suggested.

Overall, Musk has paid a heavy price for becoming such a visible Trump supporter and subsequently falling out with him. And, so far the public appears to be on Trump’s side.
